Trade: Sports Prediction Markets taxed as gambling?
Resolution criteria on PolyGram: This market will resolve to "Yes" if, by April 15, 2027, 11:59 PM ET, the IRS or U.S. Department of the Treasury publishes formal guidance classifying losses from CFTC-regulated sports event contracts as subject to the 90% loss cap under Section 165(d) of the Internal Revenue Code, as amended by the One Big Beautiful Bill Act (Public Law 119-21). Otherwise, this market will resolve to "No". For purposes of this market, sports event contracts are contracts whose payoff is determined by the outcome, score, or statistical result of an athletic competition listed on a CFTC-designated contract market or swap execution facility.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

Market context
The core question is whether the U.S. Internal Revenue Service will issue formal guidance by April 2027 treating losses from CFTC-regulated sports betting contracts as subject to the 90% loss limitation under Section 165(d) of the Internal Revenue Code, a provision introduced in the One Big Beautiful Bill Act (Public Law 119-21). This hinges on whether the IRS classifies such contracts as "wagering transactions" under the amended statute. The current order book on Polymarket reflects a 37% implied probability of YES, suggesting traders assign meaningful but minority odds to formal IRS guidance arriving within the settlement window.
Historical precedent offers limited clarity. The IRS has historically treated sports betting losses as personal losses subject to standard deduction rules, whilst derivatives on sports outcomes have occupied ambiguous territory between gambling and financial instruments. The Treasury Department's treatment of CFTC-regulated contracts—which occupy a distinct regulatory space from traditional sportsbooks—remains unsettled. No comparable recent guidance on loss limitations for exchange-traded sports derivatives exists, leaving traders to extrapolate from broader tax policy trends and the legislative intent behind the One Big Beautiful Bill Act.
Key catalysts include Treasury Department rulemaking announcements, Congressional inquiries into sports betting taxation, and any IRS Chief Counsel guidance memoranda addressing the intersection of CFTC regulation and Section 165(d). The settlement window extends to mid-April 2027, meaning traders should monitor Federal Register notices and Treasury testimony throughout 2026 and early 2027. The absence of guidance to date, combined with the technical complexity of distinguishing CFTC contracts from traditional wagering, suggests the probability reflects genuine uncertainty rather than consensus expectation.

How active is this market?
$33K in lifetime turnover and $114K of resting liquidity puts this market in the around the median by volume for taxes contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.
Last 24 hours alone saw $5K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.

Risk and regulatory note
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
