The WSOP announced three rulebook changes for the 2026 Summer Series, which begins May 26 at the Horseshoe. One modification stems directly from last summer's scandal involving the 2025 Millionaire Maker and ClubWPT Gold, a sweepstakes poker platform that created controversy in the poker community.

The organization has not yet detailed all three changes in the available information, but the rule adjustments signal the series' commitment to addressing integrity concerns. The Millionaire Maker, traditionally one of the WSOP's marquee events, drew significant player interest but faced reputational challenges that prompted organizational response.

These modifications will affect every player entering 2026 events. The WSOP's decision to revise regulations based on documented problems demonstrates how high-profile incidents shape tournament standards. Players must review the updated rulebook before registration to understand new requirements and restrictions.

The May 26 start date gives the poker community time to digest these changes before the summer grind begins. Expect these rules to influence gameplay dynamics and player behavior throughout the series.
