Do you pay taxes on Polymarket?

The short answer: taxable, even without a form

For a US taxpayer, money made on Polymarket is generally taxable, and the confusion almost always starts with the missing paperwork. A stock brokerage sends a 1099 that pre-fills much of a return, so many people assume that no form means no tax. That is not how the rule works. The IRS position is that income is income when it is realized, and the duty to report attaches to the actual gain or loss regardless of whether a platform issues a document. Polymarket does not currently issue one, so the burden of tracking and reporting sits entirely with the trader.

The genuinely unsettled part is not whether the profit is taxable but how it should be characterized. As of 2026 the IRS has issued no revenue ruling, private letter ruling, or FAQ that classifies event contracts for a CFTC-regulated prediction market, so tax professionals apply general frameworks by analogy. The rest of this page lays out those frameworks and the facts that decide which one an accountant reaches for. None of it is tax advice, and a licensed preparer should make the call for any specific return.

Does Polymarket issue a 1099 or report to the IRS?

As of 2026, no. The original on-chain market on Polygon has never sent US users a 1099-B, a 1099-DA, or a W-2G, and Polymarket has not committed to issuing one for event contracts on its CFTC-regulated US venue either. There is also no de minimis threshold that exempts small amounts: unlike some hobby-income rules, speculative and wagering income has no under-600-dollar carve-out, so the reporting duty applies even to modest profit. Because every trade is recorded on a public blockchain, the raw record exists; it simply has to be reconstructed by the filer rather than delivered on a form.

One consequence worth stating plainly: the absence of a 1099 is not a shelter. It shifts work onto the taxpayer, and it removes the automatic cross-check that a broker form provides, but it does not reduce what is owed.

The frameworks US filers use, at a glance

Because the IRS has not settled the question, accountants describe Polymarket profit using one of several established frameworks. The table sets them side by side, with the form each uses and the rate it implies, stated as of 2026. It describes the landscape; it does not endorse one route over another.

Frameworks reflect how tax professionals are filing prediction-market positions as of 2026. The IRS has issued no binding guidance, so the correct treatment for a given return is a judgment call for a licensed preparer.

Capital gains versus gambling versus catch-all

The most common approach treats each contract as a capital asset. Under it, the difference between what a position cost and what it returned is a capital gain or loss reported on Form 8949 and Schedule D. Since almost every Polymarket market resolves in days or weeks, the gain is usually short-term and taxed at ordinary income rates; the long-term rates of 0, 15, or 20 percent only reach positions held more than a year, which are rare here. A competing view applies the gambling framework, treating profit as wagering income on Schedule 1 and losses as an itemized deduction on Schedule A, capped at the amount of winnings.

A third, more conservative route reports net profit as other income on Schedule 1 without claiming a preferential rate and without the capital loss offset. Which of these an accountant chooses turns on how they characterize the instrument, and reasonable professionals disagree. That disagreement is the practical reason two people with identical trades can file them differently. The site does not tell anyone which to use; for context on why regulators themselves argue about whether these contracts resemble wagering, see is Polymarket gambling.

What changed in 2026: the loss cap and Section 1256

Two developments shape the 2026 picture. First, the One Big Beautiful Bill Act tightened the gambling framework: where losses could previously offset winnings dollar for dollar, only 90 percent of losses can now be deducted against winnings. For anyone using the gambling treatment, that means a year that nets to zero on paper can still produce a taxable amount, because a slice of the losing side is no longer deductible. Second, the argument that event contracts qualify as Section 1256 contracts became more prominent once Polymarket routed US activity through a CFTC-regulated designated contract market.

Section 1256 matters because it carries a distinctive 60/40 rule: 60 percent of the gain is treated as long-term and 40 percent as short-term, regardless of how briefly a position was held, and it is reported on Form 6781. Some professionals view the regulated US venue as a plausible candidate for that treatment while treating it as higher risk for the geoblocked on-chain market. The IRS has not confirmed that event contracts meet the statutory definition, so this remains contested rather than settled. It is one more reason the same trade history can be filed more than one way in 2026.

Reconstructing your records from on-chain data

Whatever framework applies, the filer has to supply the numbers, and this is where the public nature of the data helps. Every position, price, and resolution is recorded on Polygon under a wallet address, so a full transaction history can be exported rather than reconstructed from memory. Two things make the arithmetic fiddly. Balances settle in USDC, which the IRS classifies as property rather than cash, so disposing of a position is a taxable event even when no dollars leave the platform. And cost basis has to be tracked per contract, because a single market can be entered and exited several times.

Practically, most people pull their history either from the wallet itself or from Polymarket's public data endpoints, then hand the export to a preparer or a crypto tax tool. The same free endpoints that this desk reads to build the public leaderboard expose a wallet's positions and trades, so the raw material for a return is available without any special access. For what those endpoints return and how to reach them, see does Polymarket have an API, and for how we collect the figures on this site, see the methodology page.

Outside the United States

Everything above describes the US, because that is where the bulk of the public tax discussion sits and where the missing-form confusion is most acute. Tax on Polymarket profit is ultimately set by the country where a person is tax resident, and the treatment varies widely: some jurisdictions tax speculative or trading gains, some tax gambling winnings on a separate schedule, and a few tax certain wagering profit lightly or not at all. Polymarket does not withhold or report to foreign authorities on a user's behalf, so the same self-tracking burden applies. Anyone outside the US should confirm the rule with a local professional rather than assume the US framing carries over.
