This market will resolve to “Yes” if anyone completes a perfect bracket for the 2026 Men's Basketball NCAA Tournament on any of the following websites: ESPN, NCAA.com, CBS Sports, Yahoo Fantasy, Fox Sports, Sports Illustrated, USA Today, Kalshi. Otherwise, this market will resolve to “No”. A perfect bracket is defined exclusively as a bracket that selects the correct outcome of every game during every round of the 2026 Men's Basketball NCAA Tournament. A perfect bracket only qualifies for a completed tournament. Perfect brackets for incomplete or partially completed tournaments 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 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.Trader consensus prices "No" at 99.9% implied probability after all perfect brackets in major pools like ESPN Tournament Challenge, NCAA.com Bracket Challenge, Yahoo, and CBS Sports were eliminated during the second round of the 2026 Men's March Madness. The final holdout, which nailed the first 44 games, busted on March 22 when No. 6 seed Tennessee upset No. 3 Virginia 79-72, following earlier second-round shocks like No. 2 Purdue over No. 7 Miami and No. 5 St. John's over No. 4 Kansas. With Final Four matchups completed on April 4—including top-seeded Michigan Wolverines defeating Arizona and No. 2 UConn edging Illinois—and the championship looming April 6, over 60 of 63 games are done, rendering perfection mathematically impossible. No verified perfect bracket has ever existed in NCAA history, cementing trader certainty; no realistic scenarios remain to alter this outcome.
