SCOTUS timeline: ruling by June 2027 at earliest

A possible June 2027 decision

The US Supreme Court could rule on the dispute over sports prediction markets as early as June 2027, according to igaming.org, citing gaming attorney Daniel Wallach. That is his assessment of the earliest realistic outcome, rather than a confirmed court timetable.

Wallach’s accelerated scenario would involve the Court granting certiorari in December/January, hearing arguments in March/April and issuing a decision by June 2027. Each step remains conditional on the Court taking up the dispute.

New Jersey petition puts review in focus

New Jersey has already petitioned the Supreme Court to review a decision favoring Kalshi, according to igaming.org. Kalshi received an extension and has until November 9 to respond to that petition.

The dispute concerns whether state gambling laws apply to sports event contracts. According to igaming.org, disagreement among federal appeals courts has developed over the past six months. The Third Circuit sided with Kalshi in April, treating the contracts as swaps governed by federal commodities law.

What it means for prediction markets

• Timing remains conditional: June 2027 represents Wallach’s earliest realistic ruling date, not a commitment from the Supreme Court.
• The next identified deadline is November 9: Kalshi’s response to New Jersey’s petition precedes the December/January review window in Wallach’s scenario.
• Review and outcome are separate questions: The timetable does not indicate how the Court would resolve the dispute over state gambling laws and federal commodities law.
