Olivia Rodrigo's first Daisy Chain Fields festival drew roughly 45,000 people to Irvine's Great Park in Southern California, with proceeds supporting organisations focused on women's and girls' causes. Held in sweltering heat, the inaugural event ran smoothly and featured an all-women lineup, part of Rodrigo's broader push to combine music with charitable fundraising and highlight women-owned businesses at the site.

The single-day event featured 14 acts across two stages, including Mitski, Doechii, Chappell Roan, Santigold, The Breeders and Bikini Kill, alongside headliner Rodrigo. During her set, Rodrigo announced $10 million would be donated to charity, before Melinda French Gates joined her onstage to double that pledge to $20 million, with beneficiaries including Planned Parenthood, Baby2Baby and the Center for Reproductive Rights. Girl group KATSEYE largely withdrew after a member's ankle injury, though three members made a brief appearance, while a philanthropy village on site let attendees engage directly with the supported charities.
