Viewership stats from March Madness are in, with the first two rounds of the 2024/25 NCAA women’s basketball tournament ranking as ESPN’s second most-watched on record across all platforms.
Trailing only 2024’s Caitlin Clark-fueled historic postseason, 2025’s slate of 32 first-round games averaged a 43% increase over 2023's edition, with ABC enjoying its second-highest first-round viewership ever.
ABC's first-round average of 1 million fans came in part because 1.1 million tuned into No. 2-seed UConn's 103-34 thrashing of No. 15-seed Arkansas State last Saturday, securing the network it's third-highest single-game first-round viewership on record.
In a non-championship round that saw the highest average margin of victory in March Madness history — a differential well over 26 points — last weekend's first round also gave ESPN its second-best viewership stats since 2008.

March Madness second round scores even higher
As the competition's temperature rose in last weekend's second round, so too did viewership, with ESPN's platforms snagging a 60% overall boost over the same round in 2023, earning an average of nearly 1 million viewers across the 16 games.
Yet again, the Huskies led the charge, with UConn's 91-57 blowout win over No. 10-seed South Dakota State drawing an average of 1.7 million fans to ESPN on Monday night — an audience large enough to rank as the fifth most-viewed second-round game in history.
Joining UConn's victory in the NCAA tournament's Top 10 most-watched second-round games are No. 1-seed South Carolina's 64-53 Sunday win over No. 9-seed Indiana and No. 1-seed USC's 96-59 defeat of No. 9-seed Mississippi State on Monday.
The defending national champion Gamecocks' second March Madness matchup jumped into that elite echelon by averaging 1.4 million viewers on ABC, with the Trojans's heartbreaking yet heroic win garnering 1.3 million average fans on ESPN.
All in all, while last year’s historic peaks won’t be easy to replicate, this year’s numbers indicate consistent year-after-year growth across a wider variety of teams — signaling that this season’s strength lies in its breadth of star power, as both superstars and unique storylines compete in every bracket quadrant.
