Diaz will make his return to MMA at the Intuit Dome in Los Angeles, where he will face Mike Perry on the Ronda Rousey vs. Gina Carano card, broadcasting live on Netflix. The event is one of the most talked-about fight nights of the year, and Kalshi's signature green logo will be prominently displayed across the waistline on the back of Diaz's shorts, putting the brand front and center before a massive global audience.

The partnership spans multiple touchpoints, including NIL usage of the Nate Diaz name and likeness, billboard placements, a co-branded social media campaign, branded merchandise, and promotional posts. Kalshi's sponsorship of Diaz's shorts serves as the cornerstone activation for fight night.

"Nate Diaz is one of the most authentic, fearless competitors in sports," said Valeria Vouterakou, counsel at Kalshi. "He’s exactly who we want representing the brand."

“Kalshi came in and showed the love and support for me for this fight and the overall brand,” said Diaz. “It’s good to be in business with them.”

Financial terms of the deal were not disclosed. The partnership was brokered by Andrew Capucetti, Brad Baskin, and Zach Rosenfield.
