Resolution criteria on PolyGram: This market will resolve to "Yes" if the Supreme Court of the United States grants certiorari in a case explicitly concerning the legality, regulation, or jurisdictional authority over sports event contracts by July 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No." A case qualifies if it addresses at least one of the following: (1) whether contracts based on sporting event outcomes constitute regulated derivatives under the Commodity Exchange Act; (2) whether federal regulation via the Commodity Futures Trading Commission preempts state-level gambling laws as applied to such contracts; or (3) whether sports event contracts offered by federally licensed markets may legally…
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 outcomes
| July 31 | 11% YES | 89% NO |
| December 31 | 24% YES | 77% NO |
The Supreme Court would need to grant certiorari in a case addressing sports event contract regulation—specifically whether such contracts fall under federal derivatives law or state gambling jurisdiction—by 31 July 2026. The current order book on Polymarket prices this outcome at 10% implied probability, reflecting substantial scepticism that the Court will take up this particular legal question within the specified timeframe.
The low probability reflects historical patterns: the Supreme Court receives roughly 7,000 petitions annually but grants certiorari to fewer than 70 cases. Sports betting and derivatives regulation have generated significant lower-court activity, particularly following the 2018 Murphy v. NCAA decision, which struck down the Professional and Amateur Sports Protection Act. However, cases addressing the intersection of sports contracts with Commodity Exchange Act definitions or CFTC preemption over state gambling regimes remain relatively sparse. The Court has shown limited appetite for granular regulatory disputes absent a clear circuit split or constitutional dimension.
Traders should monitor developments in ongoing litigation involving sports betting platforms and derivatives classification, particularly any cases advancing through federal appeals courts that might create the jurisdictional conflict necessary to attract Supreme Court attention. The Federal Circuit and Second Circuit have handled related regulatory questions, though none has yet crystallised into the precise legal question this market requires. Announcements from the CFTC regarding enforcement actions against sports-contract platforms, or significant state-level legislative changes to gambling frameworks, could alter the trajectory of pending cases and shift the probability materially before the July 2026 deadline.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "SCOTUS accepts sports event contract case by 2026?" are the same as any other PolyGram political event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$947K in lifetime turnover and $21K of resting liquidity puts this market in the top 10% by volume for politics contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.
Last 24 hours alone saw $174 in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for 11 months — long enough that the order book is mature and price is well-anchored to fundamentals.
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.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a 2-hour dispute window opens, and if uncontested the payout is final. Contested outcomes escalate to UMA token holders.
This prediction market is scheduled to close on 31 December 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

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.
