The certiorari grant must be publicly confirmed via the official SCOTUS docket or orders list, and verifiable through credible legal reporting or the Supreme Court’s official website. The case does not need to be heard, scheduled, or decided to qualify. 

The resolution source will be a consensus census of credible reporting.

If this resolution source is unavailable at check time, this market will remain open until the Kaito Info Markets page comes back online and resolve based on the first check after it becomes available.

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.

Qualifying guidance must be published in the Internal Revenue Bulletin or the Federal Register as a Revenue Ruling, Revenue Procedure, IRS Notice, IRS Announcement, final or temporary Treasury Regulation, or proposed Treasury Regulation that remains published without withdrawal for at least 30 calendar days after its Federal Register publication date. Guidance qualifies if it expressly applies Section 165(d) to such contracts or classifies them as wagering transactions for federal income tax purposes. Guidance classifying sports event contracts as wagering solely for purposes of Section 4401, Section 6041, Section 3402(q), or other Code sections that do not bear on the deductibility of losses does not qualify. Non-qualifying actions include Private Letter Rulings, Chief Counsel Advice, Tax Court decisions, IRS official statements, Congressional testimony, and web-based publications not appearing in the Internal Revenue Bulletin or Federal Register. A final and non-appealable decision of the U.S. Supreme Court holding that CFTC-regulated sports event contracts are subject to Section 165(d) also qualifies for resolution.

This market will resolve to "No" if qualifying guidance is withdrawn, modified into non-qualifying form, or superseded by non-qualifying guidance before April 15, 2027; if federal legislation repeals Section 165(d) or exempts CFTC-regulated sports event contracts from its application; if federal legislation establishes a tax treatment for sports event contracts incompatible with Section 165(d) prior to qualifying guidance being issued; or if the CFTC prohibits the listing of sports event contracts on all CFTC-designated contract markets before any qualifying guidance is issued.

The resolution source for this market is the Internal Revenue Bulletin (irs.gov/irb) and the Federal Register (federalregister.gov).
