Trader consensus pins "Yes" at 100% for any bracket surviving the NCAA tournament's first round, driven by the massive volume of entries—over 25 million across ESPN, Yahoo, and CBS pools—overwhelming even slim odds of perfection. Historically, every March Madness since 2005 has seen multiple perfect first-round brackets, with thousands often intact after 32 games despite upsets like No. 11s toppling 6-seeds. Recent 2024 developments, including early Cinderella runs by Oregon and Texas A&M, haven't derailed the math: chalk-heavy outcomes favor popular picks. A zero-perfect scenario would require unprecedented chaos across all regions, an extreme outlier given the wisdom of crowds in seeding consensus.

A perfect bracket is defined exclusively as a bracket that selects the correct outcome of every game during the First Round (Round of 64) of the 2026 Men's Basketball NCAA Tournament. A perfect bracket only qualifies for a completed First Round. Perfect brackets for incomplete or partially completed First Rounds will not be considered. No form of ‘second chance’ bracket will be considered. Only brackets that can be verified as having been submitted before the start of the first Round of 64 game will be considered.
If the 2026 Men's Basketball NCAA Tournament First Round is cancelled, postponed after April 20, 2026, 11:59 PM ET or the 2026 Men's Basketball NCAA Tournament matchups have not been declared within that timeframe, this market will resolve to "No".
The primary resolution source will be official information from ESPN, NCAA, CBS Sports, Yahoo Fantasy, Fox Sports, Sports Illustrated, USA Today, or Kalshi.
