The market question was straightforward: which team would emerge victorious from the contest, scheduled for 12:00 AM ET on March 21.

Leading up to the highly anticipated matchup, both teams had navigated challenging first-round games. The No. 1-seeded Duke Blue Devils, despite their top billing, faced an unexpected scare from No. 16 seed Siena, ultimately securing a tighter-than-expected 71-65 victory. Meanwhile, the No. 9-seeded TCU Horned Frogs also experienced a hard-fought contest, narrowly defeating Ohio State 66-64 to advance.

Analyzing the market's current prices prior to the game, the sentiment was overwhelmingly in favor of Duke. The 'Duke Blue Devils' outcome was trading at an astonishing 0.9995, implying a 99.95% probability of victory according to market participants. Conversely, the 'TCU Horned Frogs' outcome was priced at a minuscule 0.0005, representing a mere 0.05% chance of an upset. This stark contrast in pricing underscored the market's strong belief in Duke's superior talent and pedigree, despite their shaky first-round performance. Traditional sportsbooks also heavily favored Duke, with spreads typically ranging from -10.5 to -12.5 points and moneyline odds as high as -893 for the Blue Devils, compared to +573 for TCU.

Expert analysis leading into the game echoed the market's strong lean towards Duke. Many analysts acknowledged Duke's depth of talent and defensive capabilities as key factors, even as they cautioned against another slow start.
