Will there be a perfect NCAA bracket?

Prediction market · Polymarket

Overview

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.

Recent developments, including double-digit seeds like Oakland and NC State advancing, shattered early perfection paths. While a flawless favorites' run through Elite Eight and beyond remains mathematically possible, it would require unprecedented chalk outcomes amid mounting injury concerns and fatigue, keeping slim \"Yes\" hope alive but trader skepticism firm.",
