Trader sentiment for the NCAA Tournament national champion seed remains tightly contested, with the 9-seed edging out the 1-seed (47.5% vs. 44.5%) and 2-seed (43%) due to Cinderella momentum from mid-major upstarts like a surging 9-seed team on a hot streak through the Sweet 16 and Elite Eight. Bracket paths favor balanced regions where top seeds face injury concerns—such as questionable status for star players on multiple 1-seeds—and rest disadvantages after grueling conference tournaments. Recent developments, including upset wins by 6- and 4-seeds, underscore the tournament's volatility, where historical data shows non-1-seeds claiming 75% of titles since 1985, keeping the wisdom of crowds priced in a narrow band atop the market.
