March Madness is here, and millions of basketball fans are tuning in to the frenzy. According to new Harris Poll research, a significant portion of the U.S. population plans to watch the 2025 NCAA Men’s and Women’s March Madness tournaments — more than half (54%) of U.S. adults say they plan to follow either the men’s or women’s tournaments this year.

Sports — whether it’s March Madness, the Super Bowl or a regular season match-up — have a unique ability to bring people together.

“March Madness is a prime example of how college basketball is becoming more than just a sport — it’s a powerful business and cultural force,” says Will Johnson, CEO of The Harris Poll. “It doesn’t just bring people together, it ignites conversations and creates real opportunities for advertisers to connect with diverse audiences. Whether you’re rooting for a team or hoping for an upset, the men and women’s tournaments drive engagement like few other events.”

Our polling shows that nearly 50% of Americans believe watching and playing sports helps them connect with people from different backgrounds. And what better way to bond than by cheering for the same team, whether it’s to win or lose?

Who’s Watching? The NCAA tournaments are particularly popular among younger adults and people of color. More than two-thirds of adults aged 18-34 (68%) plan to follow at least one tournament, while 64% of people of color expressed the same intent, compared to 48% of White U.S. adults. Meanwhile, 18% of viewers will follow both the men’s and women’s tournaments, signaling broad interest across the board.

The Teams Fans Want to See Win and Lose

Men’s Tournament:

When it comes to the men’s tournament, fans have strong opinions about who they’re rooting for — and against. A majority (84%) of those following the men’s tournament are excited to see at least one of the top 16 teams succeed.

Notably, fans are particularly invested in teams like Duke (26%), Florida (21%), and Michigan State (16%). However, the sentiment shifts when it comes to teams they’d like to see lose. Roughly 72% of fans have a team in mind that they’d like to see exit early. Duke, Kentucky, and Alabama were the most mentioned teams for a potential upset.

But similar to the men’s side, there’s no shortage of fans hoping for surprises. About 72% of viewers have teams they’d be pleased to see eliminated, with UConn, South Carolina, and LSU being the most commonly cited teams.

Interestingly, the rankings slightly shift among March Madness “superfans,” or those planning to watch both tournaments — but not by much. For the men’s tournament, Michigan State moves down the list of fan-favorites, replaced by Tennessee. For the women’s tournament, UConn becomes a top 5 team, unseating USC.

As the 2025 NCAA March Madness tournaments unfold, the drama is sure to captivate fans, with teams like Duke and UConn sparking strong reactions. While 29% of fans are cheering for Duke to win, 20% are hoping for an early exit, and UConn is equally polarizing. With such passionate and diverse opinions, this year promises plenty of surprises—whether it’s a blue-blood school or a Cinderella team making a run for the title.

This survey was conducted online in the United States by The Harris Poll from March 18, 2025 to March 21, 2025 among 2,064 US adults, aged 18+. Figures were weighted where necessary to align with actual proportions within the population. For additional information, please contact The Harris Poll.
