Bloomberg reported on 12 July 2026 that US-based participants in prediction markets stand to receive significantly more favorable tax treatment on World Cup winnings compared to traditional sportsbook users. The analysis hinges on a critical distinction in how the Internal Revenue Service categorizes proceeds from these platforms. Winnings from regulated prediction markets could be taxed as long-term capital gains, with rates capped at 20% for high earners, whereas sportsbook payouts are typically taxed as ordinary income, reaching rates as high as 37%.
Context — [why this matters now]
The 2026 FIFA World Cup, co-hosted by the United States, Canada, and Mexico, is projected to generate over $10 billion in total wagers from American citizens. This massive volume places unprecedented scrutiny on the tax implications of emerging betting platforms. The regulatory landscape for prediction markets has evolved since the Commodity Futures Trading Commission granted designated contract market status to platforms like Kalshi, which allows them to offer event-based contracts legally.
A key historical precedent was set in 2025 when a US Tax Court ruling on profits from a political prediction market case suggested that such activity could be framed as a form of speculative investment rather than pure gambling. The current US individual income tax system features seven brackets, with the top rate of 37% applying to taxable income above $609,350 for single filers. In contrast, the long-term capital gains rate for that same income level is 20%.
The catalyst for this specific analysis is the impending start of the World Cup group stage matches in June 2026. The event's scale and the involvement of a US host nation have accelerated regulatory and tax guidance from federal agencies. This has created a clear, time-sensitive distinction between the two primary channels for event-based wagering.
Data — [what the numbers show]
The potential tax savings are significant when comparing the two betting methods. A high-net-worth individual in the top tax bracket winning $100,000 on a sportsbook would owe $37,000 in federal taxes, leaving $63,000. The same win on a qualified prediction market, taxed at the long-term capital gains rate, would incur a $20,000 liability, netting the bettor $80,000—a 27% increase in after-tax proceeds.
| Betting Method | Payout | Tax Rate | After-Tax Value |
|---|
| Sportsbook | $100,000 | 37% | $63,000 |
| Prediction Market | $100,000 | 20% | $80,000 |
The distinction applies primarily to profits held for more than one year on prediction markets. Short-term gains are taxed at ordinary income rates, identical to sportsbooks. The US sports betting market handled an estimated $120 billion in wagers in 2025, with online platforms capturing nearly 85% of that volume. Prediction markets currently represent a fraction of this total but are experiencing rapid growth.
Analysis — [what it means for markets / sectors / tickers]
The tax advantage could redirect significant capital flows towards operators of legal prediction markets. Publicly traded sportsbook companies like DraftKings (DKNG) and FanDuel parent Flutter Entertainment (FLUT) may face increased competition for high-value, sophisticated bettors. Conversely, private platforms with CFTC approval, such as Kalshi, stand to gain market share, potentially enhancing their valuation ahead of anticipated initial public offerings.
The regulatory arbitrage also creates a new product category for wealth managers and tax advisors. Firms like Morgan Stanley (MS) and Charles Schwab (SCHW) may develop strategies for clients seeking to optimize after-tax returns from speculative activities framed as investments. A key limitation is that the tax treatment is not universally guaranteed; the IRS may challenge individual cases where prediction market activity is deemed to lack investment-like characteristics, such as a profit motive beyond mere recreation.
Institutional flow is likely to favor prediction markets for large, strategic wagers where the tax savings materially impact returns. Retail investors may be slower to migrate due to the complexity of the platforms and the long-term holding requirement for preferential rates. Broker-dealers facilitating these markets could see an uptick in transaction volume.
Outlook — [what to watch next]
The primary catalyst is the conclusion of the World Cup on 19 July 2026 and the subsequent tax filing season in early 2027. The first IRS rulings on World Cup prediction market winnings will set a critical precedent for future sporting events. Market participants should monitor for any public guidance from the IRS on the classification of event contract profits, expected by Q4 2026.
Key levels to watch are the trading volumes on platforms like Kalshi versus traditional sportsbooks for the World Cup final. A significant divergence would signal market sensitivity to the tax disparity. The 20% long-term capital gains rate is a critical threshold; any legislative proposals to increase this rate would diminish the prediction market advantage. The next major test case will be betting markets for the 2028 US Presidential election.
Frequently Asked Questions
How does the IRS distinguish between gambling and investing?
The IRS distinguishes based on intent and activity. Gambling involves wagering on events with an element of chance primarily for entertainment. Investing implies a sustained, profit-seeking enterprise. Factors include the frequency of transactions, the application of analytical skill, and the holding period. Prediction market activity that resembles trading—such as building a diversified portfolio of contracts over time—is more likely to be classified as investing for tax purposes.
What are the risks of using prediction markets for US bettors?
The primary risk is regulatory uncertainty. While some platforms are CFTC-regulated, the IRS has not issued blanket guidance, leaving room for case-by-case challenges. Bettors could face audits and potential reclassification of gains as ordinary income, plus penalties. There is also counterparty risk; using unlicensed offshore prediction markets offers no tax benefit and may be illegal. Liquidity risk is higher than with major sportsbooks, impacting the ability to enter or exit positions at desired prices.
Does this tax advantage apply to cryptocurrency-based prediction markets?
No, winnings from decentralized, crypto-native prediction markets like Polymarket do not currently qualify for capital gains treatment. These platforms operate in a regulatory gray area and are not designated contract markets. The IRS treats cryptocurrency as property, so gains from such platforms would likely be considered short-term or long-term capital gains based on holding period, but the underlying activity may still be deemed illegal gambling by other regulators, creating significant legal risk.
Bottom Line
The tax code creates a material after-tax return advantage for World Cup bets placed on regulated prediction markets versus traditional sportsbooks.
