The women's college basketball markets witnessed stunning overnight collapses, with UConn (+160) leading the women's March Madness odds for the 2027 NCAA Tournament and losing its undefeated season in an upset loss to South Carolina in the Final Four. LSU's title odds plummeted from 99¢ to 10¢, while TCU crashed from 99¢ to just 5¢ — dramatic drops that indicate their 2026-27 championship hopes are effectively over. Meanwhile, USC's odds rocketed from 22¢ to 68¢, suggesting the Trojans are emerging as a serious contender for next year's title. The market is pricing in massive program-shifting events, with both the men's and women's NCAA basketball tournaments expected to expand to 76 teams, effective next year, adding 8 more teams to March Madness starting in 2027.
