Key Facts
- 1Prediction market bettors could deduct 100% of losses against gains (plus up to $3,000 against ordinary income), while sportsbook bettors can only deduct losses to the extent of winnings and only if itemizing.

- 4The 2026 FIFA World Cup, which began June 11, is driving a surge in betting, highlighting the tax disparity between platforms.

Analysis
For the crypto community, the World Cup isn't just about goals—it's a testnet for decentralized prediction markets' tax superiority. With the IRS yet to rule on whether on-chain event contracts are securities or gambling, users are potentially locking in 20% effective tax rates, a stark contrast to the 37% bite from fiat sportsbooks.
As the 2026 FIFA World Cup entered its knockout stage in mid-July, millions of Americans placed bets not only at traditional sportsbooks but also on emerging prediction market platforms like Kalshi and Polymarket. What many may not realize is that the tax treatment of those wagers could differ dramatically—potentially cutting the effective tax rate by 17 percentage points or more—because prediction market contracts are legally structured as financial instruments rather than gambling wagers. The Internal Revenue Service has remained conspicuously silent on the classification, creating a high-stakes tax arbitrage opportunity for bettors and a compliance headache for tax professionals.
In contrast, investment gains enjoy preferential capital gains rates: 0%, 15%, or 20% for long-term holdings, with the full deduction of capital losses against gains and an additional $3,000 allowance against ordinary income.
Under current U.S. tax law, gambling winnings are treated as ordinary income, subject to federal rates as high as 37% for top earners, plus state taxes. Losses can only be deducted to the extent of winnings and only by taxpayers who itemize deductions, making it a punitive regime for high-frequency bettors. In contrast, investment gains enjoy preferential capital gains rates: 0%, 15%, or 20% for long-term holdings, with the full deduction of capital losses against gains and an additional $3,000 allowance against ordinary income. Some tax practitioners argue that event contracts—standardized, exchange-traded products that pay out $0 or $1 based on the outcome of a future event—may qualify for the even more favorable Section 1256 mark-to-market rules. Under Section 1256, gains are taxed as 60% long-term capital gain and 40% short-term, regardless of the holding period, yielding a blended top rate of just 23.6% under current law. For a World Cup bettor in the highest bracket, this could mean an effective tax rate nearly 13.4 percentage points lower than on a sportsbook win—or up to 37 percentage points lower for lower-income filers who might owe 0% on the long-term portion.
The practical consequences are already visible. The 2026 World Cup, which began June 11 and runs through July 19, is expected to generate billions in betting handle globally. Prediction market platforms have seen a surge in trading volume on World Cup-related event contracts, from match winners to goal totals. Kalshi, the first CFTC-regulated prediction exchange, lists contracts that settle to cash based on verified outcomes. Polymarket, a crypto-native decentralized platform, facilitates similar trades using smart contracts on a blockchain, though it operates outside U.S. regulatory permission. Both promote the investment-like nature of their products, yet neither can guarantee the tax treatment. Tax preparers interviewed by Accounting Today say they are fielding inquiries from clients who want to report prediction market winnings as capital gains, but are advising caution. The IRS has historically employed the substance-over-form doctrine to recharacterize transactions that are economically equivalent to gambling, and a court challenge could upend any aggressive filing position.
What to Watch
The legal ambiguity is compounded by the political sensitivity around prediction markets. In recent years, high-profile figures like Elon Musk have reportedly explored prediction market ventures, and the CFTC has been both courted and criticized for its oversight. The IRS, which is already grappling with guidance on cryptocurrency staking, DeFi income, and digital asset basis tracking, may be reluctant to issue a ruling that either legitimizes or heavily restricts a politically charged product during an election year. That leaves bettors in a gray zone: they can claim the tax benefits but must weigh the risk of an IRS audit, accuracy-related penalties of 20% of the underpayment, and possible interest. For those who made substantial profits, the tax savings could be significant enough to justify the risk, but for average bettors, the administrative burden alone may be prohibitive.
Looking ahead, the outcome of this tax uncertainty could reshape the rapidly growing prediction market industry. If the IRS eventually blesses investment treatment, event contracts could become a staple of retail trading accounts alongside stocks and ETFs, further blurring the line between betting and investing. Platforms would attract capital not only for sports but for political and economic events, potentially competing with traditional derivatives exchanges. Conversely, a ruling that such contracts are gambling would dent the platforms’ value proposition, possibly forcing them to restructure or face a exodus of tax-conscious users. In the immediate term, tax advisors are urging clients to document their trades meticulously and consider filing protective refund claims. As the World Cup reaches its final, millions of dollars in tax liability hang on a question the IRS has yet to answer: when is a bet not a bet?

How we covered this story
Every story in our crypto coverage is assembled from multiple primary sources, cross-referenced for factual consistency, and scored along three independent dimensions: sentiment, operational impact, and source-cluster confidence. Single-source rumors and unverifiable claims do not pass our editorial gate. When a story shows "Verified by N sources" with N≥2, the development is independently corroborated; when N=1, we mark it explicitly so readers can weigh the signal accordingly.
Impact scoring uses a 1-10 scale weighted toward regulatory, financial, and operational consequence rather than coverage volume. A topic that runs in every outlet but moves no real decisions ranks lower than a niche regulatory filing that reshapes how operators in the crypto space have to behave. Read our full methodology for the scoring rubric, our glossary for term definitions, and our trends index for the longitudinal view across the beat.
