Taylor vs Serrano Shatters Records: 6 Million Viewers, MSG Sellout, Guinness World Record

Katie Taylor and Amanda Serrano just made boxing history — again.

On July 11, 2025, their epic trilogy fight broke records across the board, drawing a staggering 6 million global viewers and 4.2 million in the U.S. alone via Netflix’s global livestream. It wasn’t just a fight — it was a cultural moment.

The event completely sold out Madison Square Garden, setting the biggest global boxing gate ever for a women-headlined bout. Even more impressively, it earned a Guinness World Record® for the most championship belts contested in one event.

Viewership numbers topped the charts in the U.S., Ireland, Australia, and New Zealand — and the event landed in the top 10 in 43 countries. It now stands as the #1 highest-rated U.S. pro women’s sports event of the year.

This isn’t just a win for Taylor and Serrano — it’s a massive leap forward for women’s boxing. Their rivalry has redefined what’s possible for female athletes in combat sports, and the world is watching.
