Quick answer (read this first):
The short answer: It depends and the IRS has not told you which answer applies.
What the question actually means: Whether prediction market profits are taxed as gambling income, capital gains, or ordinary income is not settled under current U.S. tax law. The IRS has issued no notice, ruling, or form instruction that directly addresses prediction market contracts. Taxpayers must apply existing legal frameworks to novel facts and reasonable professionals disagree on which framework controls.
Why characterization matters: The tax treatment is not cosmetically different across frameworks. It determines your effective rate, what you can do with losses, and whether a 2026 statutory change creates tax liability even when you roughly break even. Getting characterization wrong is not a filing error. It is a structural exposure that compounds across every year you are active in these markets.
The practical posture: In the absence of IRS guidance, a conservative, documentation-first approach built around defensible characterization,not rate optimization, is the professional standard. For a comprehensive analytical framework covering prediction market taxes across all platforms and contract types, see our complete guide.
The Question That Does Not Have a Clean Answer
Prediction markets have attracted significant trading volume, serious capital, and a growing population of active participants. What they have not attracted, at least not yet, is definitive IRS guidance on how the income should be taxed.
That gap is not incidental. It reflects a genuine structural problem which is that prediction market contracts do not map cleanly onto existing tax categories. They are not stocks. They are not futures in the traditional sense. They are not casino bets in the legal sense, despite looking like them to a casual observer. And the IRS has not yet published the analysis that resolves which category controls.
The result is that participants filing returns for prediction market activity must make a characterization decision without a statutory anchor, relying instead on analogical reasoning, existing frameworks, and their own risk tolerance. The decision is consequential, and the cost of getting it wrong depends entirely on which framework ultimately proves correct.
This article does not assert that prediction market winnings are or are not gambling income. The honest answer is that no one can assert that with authority under current law. What this article does is explain the four analytical frameworks currently in use, what each one means in practical tax terms, and why characterization is not an academic question for active traders.
What “Gambling Treatment” Would Actually Mean
Before evaluating whether gambling treatment applies, it is worth being precise about what gambling treatment actually produces. The framework is familiar in the context of casinos, sportsbooks, and racetracks. It is less familiar and far more consequential when applied to a trading-style activity generating hundreds or thousands of contract dispositions in a year.
Under gambling treatment, winnings are taxable as ordinary income in the year received. Losses are deductible only if the taxpayer itemizes, and only up to the amount of reported winnings for that year. Net losses cannot be carried forward. They cannot offset capital gains or other income. A trader who nets a loss for the year receives no tax benefit unless they itemize deductions, and even then, only to the extent of their gross winnings.
There is an additional compliance burden since the IRS requires gambling activity to be tracked on a per-session basis, not contract by contract. Within a given session, a taxpayer can net activity. But sessions cannot be netted against each other and gross winning sessions and gross losing sessions must be reported separately, with losses then deducted subject to the itemized cap. For casino gamblers, a “session” is a defined visit to a table or machine. For a prediction market trader with hundreds of contract openings, closings, and settlements occurring continuously across multiple platforms, the concept of a session has no established definition under current IRS guidance. That ambiguity is not a minor administrative detail. It creates a documentation and interpretation problem that does not exist under capital or ordinary income frameworks.
Beginning January 1, 2026, the consequences of gambling treatment became materially worse. Under the One Big Beautiful Bill Act, deductible gambling losses are now capped at 90 percent of losses, applied against winnings. It means that a taxpayer who wins $500,000 and loses $500,000 on prediction market contracts in the same year could face a federal tax bill on $50,000 of phantom income that was never economically realized. At a 37 percent marginal rate, the tax cost of breaking even under gambling treatment now exceeds $18,000.
That structural consequence is why characterization is not simply a question of rate. It is a question of whether activity that generates no economic gain can generate a tax obligation. For active prediction market traders, the 2026 loss limitation change makes this the most important tax question in the space.
Why the IRS Has Not Settled This
The IRS’s silence on prediction markets reflects the genuine analytical difficulty of the question.
Prediction market contracts defy easy categorization because they share structural features with multiple recognized categories without fitting squarely inside any of them. A prediction market contract is acquired at a price, has a market value that fluctuates before resolution, can be sold before the underlying event occurs, and settles based on a defined outcome. That lifecycle resembles a financial instrument. But the underlying event is not a price, rate, or index. It is a binary factual outcome such as an election result, a sports score, a macroeconomic threshold. That outcome-based structure has historically been associated with wagering.
Until the IRS publishes direct guidance, characterization analysis must proceed through analogical reasoning against existing Code provisions and that reasoning is unsettled.
The Four Analytical Frameworks
Current practitioner and academic discussion of prediction market characterization clusters around four frameworks. Each represents a defensible position under existing law. None is demonstrably correct to the exclusion of the others under current authority.
Gambling and wagering income. Under this framework, prediction market activity is treated as wagering. Gains are taxable as ordinary income. Losses are deductible only to the extent of winnings and only by itemizing, subject to the new 90 percent cap beginning in 2026. This framework is most commonly asserted for sports-outcome contracts on the theory that the underlying event looks like conventional betting. It is analytically weaker for macro-economic or political contracts traded on CFTC-regulated exchanges, where the exchange structure and regulatory posture cut against casino-style analogies.
Ordinary income from a contingent or non-equity contract framework. Under this framework, prediction market contracts are treated as contingent rights generating ordinary income or loss upon settlement. This is consistent with treating the contract as a non-capital asset, particularly where the taxpayer holds large positions, trades frequently, or is in a business of trading. The ordinary income characterization does not imply gambling treatment. Ordinary income from a financial contract and ordinary income from gambling are analytically distinct due to different loss rules, different reporting, different character. This framework is often underweighted in public commentary relative to its analytical coherence.
Capital gain or loss under general property principles. Under this framework, prediction market contracts are treated as property, and gains and losses are characterized under the capital asset rules. Contracts held for one year or less produce short-term capital gains and losses taxed at ordinary income rates. Contracts held longer than one year qualify for long-term rates. Net capital losses are subject to the annual $3,000 deduction limit against ordinary income, with excess losses carried forward indefinitely. This framework treats prediction markets like investment contracts, which is analytically consistent with their structure but unconfirmed by statute or guidance.
Section 1256 contract treatment. Under this framework, qualifying contracts are subject to the 60/40 blended rate with 60 percent of gains treated as long-term capital gain and 40 percent as short-term regardless of holding period. Contracts are also marked to market at year-end, with unrealized gains and losses treated as realized. Section 1256 is frequently discussed in prediction market forums as if it were an election or optimization choice. It is not. It is a statutory override that applies only when a contract satisfies the specific definitions enumerated in the Code. Whether event-based prediction contracts satisfy those definitions, particularly the regulated futures contract or nonequity option categories, remains unresolved. For a detailed analysis of whether Section 1256 applies to Kalshi and other prediction market contracts, see our dedicated analysis: Section 1256 and Prediction Markets.
Where the Gambling Risk Is Strongest
Not all prediction market activity carries the same gambling risk. The structural distinction that matters most is not the platform or the dollar denomination of settlement. It is the nature of the underlying event and the regulatory posture of the exchange. Sports-outcome contracts present the highest risk of gambling characterization. The underlying event is functionally identical to what conventional sportsbooks offer. Even where those contracts trade on a CFTC-regulated exchange rather than a state-licensed sportsbook, the analytical argument for gambling treatment is cleaner because the economic substance resembles wagering more than it resembles financial derivatives trading.
In January 2026, a Suffolk County Superior Court judge issued a preliminary injunction against Kalshi’s sports event contracts, holding that Massachusetts sports wagering licensing requirements apply to those contracts and are not preempted by Kalshi’s CFTC-regulated status. The court ruled that federal commodities oversight and state gambling licensing authority can coexist, and that Congress did not intend to strip states of their traditional power to regulate gambling when it passed the Commodity Exchange Act. Federal regulation does not preempt state gambling law in all circumstances, and the litigation landscape for sports-outcome event contracts remains genuinely contested across multiple jurisdictions. For tax purposes, the legal characterization battle at the state level is not binding on the IRS, but it is a data point about how courts are analyzing these contracts and it supports treating sports contracts as higher-risk for gambling characterization than macro or political contracts.
Macro-economic contracts present a weaker case for gambling treatment. The underlying event is a financial or economic variable, the parties are typically sophisticated traders rather than casual bettors, and the exchange structure is derivatives-facing. That does not mean it is unavailable to the IRS as a future argument, but the threshold for asserting it is higher. Political contracts sit between these two poles. The event is not a financial variable, but neither is it a sporting outcome. The CFTC’s eventual acceptance of political event contracts as federally regulated instruments cuts against gambling treatment, but state-level regulatory pressure against prediction markets as unauthorized gaming continues across multiple jurisdictions. The analytical risk is real and not fully resolved.
What Platform Reporting Tells You and What It Does Not
A common misunderstanding among prediction market participants is that the presence or absence of a tax form determines the characterization question.
Kalshi issues limited documentation including a 1099-INT for interest on cash balances, a 1099-MISC for referral bonuses, and a 1099-B only in limited circumstances tied to crypto transfers. Kalshi does not issue comprehensive broker-style reporting covering contract-level acquisition, disposition, cost basis, or annual profit and loss from event contract trading. For a detailed breakdown of what Kalshi reports and what it leaves unresolved, see our analysis: Kalshi Tax Reporting: What Your 1099 Leaves Out.
Polymarket issues no tax forms at all. The platform operates as a decentralized protocol without KYC, and no IRS-required reporting identifiers are collected. Polymarket participants are entirely responsible for self-reporting based on on-chain transaction reconstruction.
In both cases, the absence of comprehensive reporting does not simplify the characterization question. It makes it more consequential. A taxpayer who receives a 1099-MISC from Kalshi covering only a referral bonus and concludes that no further reporting is required has not resolved the question of how their event contract trading should be characterized — they have simply failed to address it. The obligation to report accurately exists regardless of what the platform provides.
The reporting gap also creates a documentation burden that is distinct from the characterization question. Even if characterization is ultimately resolved in favor of capital treatment, a trader with hundreds of contract dispositions and no platform-generated gain and loss summary must reconstruct their transaction history from raw exports, on-chain data, or account statements. Our prediction market tax reporting services are built around exactly this problem of platform reports that do not resolve character, incomplete transaction data, and the need for a defensible reporting architecture before the IRS’s matching processes surface the gap.
The Conservative Professional Posture
In the absence of IRS guidance, the most defensible professional posture for prediction market characterization is one that prioritizes documentation over rate optimization and does not treat statutory frameworks as freely available elections.
Section 1256 treatment in particular should not be treated as a default choice simply because Kalshi is CFTC-regulated. The regulated exchange status is a necessary precondition for exploring the §1256 question, not a sufficient one. Whether event-based binary contracts satisfy the specific statutory definitions, particularly against the backdrop of litigation asserting they are gambling instruments rather than financial contracts, requires factual analysis and formal position documentation, not a software checkbox.
For most prediction market participants, the current practical options are either ordinary income treatment under a contingent contract theory, or short-term capital gain treatment under a property theory. Both are analytically coherent. Both are currently defensible with proper documentation. Neither exposes the taxpayer to the phantom income risk that gambling treatment creates under the 2026 loss limitation.
The characterization decision should be made once, applied consistently across all contracts in a tax year, and documented in a way that explains the analytical basis for the position taken. An examiner reviewing a prediction market return is not bound by how the taxpayer labeled their income. They will evaluate the underlying contracts on their merits. A return supported by a formal analytical position memorandum is materially more defensible than one that treats characterization as self-evident.
This posture will remain the professional standard until the IRS publishes direct guidance. It may need to be revisited when that guidance arrives and potentially including amended returns if the IRS adopts a framework inconsistent with positions previously taken. That risk is unavoidable given the current state of the law. What is avoidable is filing without a documented position at all.
What This Means for Active Traders
For prediction market participants with material annual activity including multiple contracts, recurring dispositions, meaningful gain and loss positions the characterization is not a background question resolved at filing. It is a structural decision that shapes reporting methodology, loss treatment, and exposure management across every active tax year.
A trader who treats their activity as short-term capital gain can offset prediction market losses against capital gains from other positions, carry forward net losses, and is not exposed to the phantom income problem created by the 2026 gambling loss cap. A trader who takes a gambling position or whose return is later recharacterized by the IRS as gambling faces a materially different economic outcome, particularly if they have years where gross winnings substantially exceed net gains.
The practical starting point is a complete transaction history. Without a contract-level accounting of acquisitions, dispositions, and outcomes across the full tax year, characterization cannot be applied consistently, and no framework can be defensibly documented. Platform exports are often the beginning of that process, not the end of it. Where platform data is incomplete, on-chain records and secondary documentation must be used to reconstruct the full picture.
Working with a crypto CPA firm that has direct experience with prediction market contract mechanics, platform reporting gaps, and the current analytical landscape is the most reliable way to establish a defensible characterization position before IRS guidance arrives and before IRS matching creates pressure to respond rather than plan.
If your prediction market activity is material and your characterization has not been formally analyzed, the right time to address it is before your return is filed, not after it has been filed under an assumption that may not survive scrutiny.

Frequently Asked Questions: Prediction Market Gambling Income and Tax Characterization
Has the IRS issued guidance on whether prediction market winnings are gambling income?
No. As of 2026, the IRS has published no notice, revenue ruling, regulation, or form instruction that directly addresses how prediction market contracts should be characterized for federal income tax purposes. Taxpayers must apply existing statutory frameworks including capital asset rules, ordinary income principles, gambling provisions, and Section 1256 to contracts that do not map cleanly onto any of them. Until the IRS issues direct guidance, characterization requires analytical judgment, not a lookup.
Does Kalshi’s CFTC-regulated status mean my winnings are not gambling income?
Not automatically. Kalshi’s designation as a CFTC-regulated Designated Contract Market is relevant to the characterization analysis, and it is a meaningful distinction from state-licensed sportsbooks. But federal regulatory status under the Commodity Exchange Act does not determine federal income tax character. The IRS and the CFTC operate under separate statutory frameworks. A contract can be a federally regulated derivatives instrument and still be characterized as a wagering transaction for tax purposes. The CFTC’s jurisdiction is a factor in the analysis. It is not a dispositive answer.
What is the practical difference between gambling treatment and capital gains treatment for prediction market traders?
The difference is significant across four dimensions. First, loss treatment means capital losses can offset capital gains from other investments and carry forward indefinitely; gambling losses can only offset gambling winnings in the same year and require itemizing, with no carryforward. Second, the 2026 loss limitation under the One Big Beautiful Bill Act, deductible gambling losses are capped at 90 percent of winnings, meaning a trader who breaks even economically can still owe tax on phantom income. Third, short-term capital gains are taxed at ordinary rates, so the rate difference between capital treatment and gambling treatment may be modest, but the loss limitation asymmetry is not. Fourth, under gambling treatment the IRS requires activity to be tracked on a per-session basis, not contract by contract. Within a session wins and losses can be netted, but sessions cannot be netted against each other. For a prediction market trader with continuous contract activity across hundreds of dispositions, the definition of a session has no established meaning under current IRS guidance creating an interpretation and documentation burden that does not exist under capital or ordinary income frameworks.
If I receive no 1099 from Polymarket, do I still have to report my winnings?
Yes. The reporting obligation exists regardless of whether the platform issues any tax documentation. Polymarket does not issue 1099 forms because it operates as a decentralized protocol and does not collect the identifying information required to generate them. That does not affect the taxpayer’s legal obligation to report income from event contract dispositions. The IRS does not require a 1099 as a precondition for taxability. All income is reportable unless specifically excluded by statute, and no statutory exclusion covers prediction market winnings.
Are sports outcome contracts on Kalshi more likely to be treated as gambling than macro or political contracts?
The analytical risk of gambling characterization is materially higher for sports-outcome contracts. The underlying event, a game result, a score, a performance threshold, is structurally identical to what conventional sportsbooks offer, which creates a stronger analogical basis for gambling treatment. Macro-economic contracts such as Fed rate decisions or inflation thresholds involve financial variables more consistent with derivatives trading. Political contracts sit between the two. The exchange structure cuts against gambling treatment across all categories, but the nature of the underlying event is a relevant factor in the characterization analysis, and sports contracts present the least favorable profile.
What does the 2026 gambling loss cap mean for prediction market traders in practical terms?
Beginning January 1, 2026, gambling losses are deductible only up to 90 percent of gambling winnings for the year, even for taxpayers who itemize. For a trader with $500,000 in gross winnings and $500,000 in gross losses netting zero, gambling treatment would produce $50,000 of taxable income despite no economic gain. At a 37 percent marginal rate, the federal tax on that phantom income exceeds $18,000. The cap applies to the deductible losses, not the winnings, so it creates a structural tax cost that increases with gross trading volume regardless of net profitability. This consequence is specific to gambling treatment. It does not arise under capital or ordinary income frameworks.
Can I elect Section 1256 treatment for my Kalshi contracts to get the 60/40 blended rate?
Section 1256 is not an election. It is a statutory category that applies automatically when a contract satisfies the specific definitions enumerated in the Code including regulated futures contracts, foreign currency contracts, nonequity options, dealer equity options, or dealer securities futures contracts. Whether Kalshi event contracts satisfy any of those definitions is an unresolved analytical question. Kalshi’s CFTC-regulated status is a necessary precondition for exploring the regulated futures contract analysis, but it is not sufficient. A taxpayer claiming Section 1256 treatment is asserting that their specific contracts meet the statutory definition and must be prepared to defend that position under examination. Treating it as a default choice is not supportable under current law.
What happens if I file my prediction market income as capital gains and the IRS later determines it should have been gambling income?
If the IRS recharacterizes prediction market income as gambling on examination, the consequences depend on the magnitude of the adjustment and the taxpayer’s filing position. The recharacterization could disallow capital loss offsets, impose the gambling loss limitations including the 2026 cap, and generate additional tax, interest, and potentially accuracy-related penalties. The exposure is most significant for traders who used capital losses from other positions to offset prediction market losses, because those offsets would be unwound. A formal analytical position memorandum documenting the basis for the capital treatment taken reduces penalty exposure even if the underlying characterization is later disputed.
Do I have to itemize to deduct gambling losses from prediction market contracts?
Yes. Under IRC §165(d), gambling losses are an itemized deduction claimed on Schedule A. A taxpayer who takes the standard deduction receives no benefit from gambling losses regardless of their amount. For taxpayers who do itemize, losses are deductible only up to the amount of gross gambling winnings for the year, and beginning in 2026, only up to 90 percent of those winnings. There is an additional layer that active traders often miss, the IRS per-session rule requires gross winning sessions to be reported as income and gross losing sessions to be deducted separately. Activity cannot simply be netted before reporting. For a prediction market trader, where the concept of a session is undefined under current guidance, this creates both a reporting complexity and a potential for gross income inflation that does not arise under capital or ordinary income treatment. The practical effect is that a significant portion of the U.S. population, those for whom the standard deduction exceeds their itemized deductions, receives zero tax benefit from gambling losses under any circumstances, and even those who do itemize face a compliance structure materially more burdensome than any other characterization framework.
How should I approach prediction market tax reporting given that characterization is unsettled?
The professional standard in an unsettled area is to select a defensible analytical position, apply it consistently across all contracts in the tax year, and document the analytical basis for the position taken. Characterization should not shift from year to year without a substantive reason. The two most defensible current positions for most participants are short-term capital gain treatment under general property principles or ordinary income treatment under a contingent contract theory. Section 1256 treatment requires stronger factual support and formal analysis before it can be responsibly claimed. Gambling treatment, while analytically available for some contract types, carries the most adverse economic consequences under current law and should not be adopted without deliberate analysis. Working with a CPA experienced in prediction market contract mechanics before filing, not after, is the most reliable way to establish a position that holds under scrutiny.
