Carlos Alcaraz is bringing protein power to his endorsement portfolio.

Five-time Grand Slam champion Alcaraz has signed a multi-year deal to serve as brand ambassador for Oikos, America’s high-protein yogurt brand. Financial terms of the deal were not disclosed.

The 2022 US Open champion stars in campaign ads for the yogurt brand bearing the tagline “Stronger Makes Everything Better.”

“Strength is an important factor to me, both on and off the court. But it’s not just about how I train – it’s about how I fuel my body,” said Carlos Alcaraz. “That’s why I’m proud to partner with OIKOS. Its high-quality protein is one of the things that helps me maintain my strength.”

To celebrate the partnership with Alcaraz, Oikos has created the ultimate “drop kit” which will feature select gear, including a co-branded tennis bag and hat with Carlos Alcaraz’s signature, Oikos-branded socks, sweatbands, tennis balls, and a fan-favorite muscle recovery tool. 

The kits will debut on social media channels this month, just in time for the US Open, with more to come from Alcaraz in 2026.
