Beverage company Electrolit has strengthened its presence in tennis after striking a multi-year sponsorship deal with the hardcourt US Open grand slam.

The new agreement, struck with tournament organizer the US Tennis Association (USTA), will see Electrolit become the official electrolyte beverage of the US Open from the upcoming 2026 edition, which will run from August 30 to September 13.

Under the deal, Electrolit products will be made available to all US Open players via branded on-court coolers and other player-facing areas, with the brand to gain promotional space on the USTA Billie Jean King National Tennis Center grounds.

The partnership also features on-court branding that will be visible during domestic rightsholder ESPN’s coverage of the main draw.

The deal deepens Electrolit’s presence in tennis, having signed up two-time US Open champion Aryna Sabalenka and American Emilio Nava as athlete partners.

The brand also served as the official hydration sponsor of the Miami Open in 2024 and 2025, as well as the official sports drink of the Madrid Open in 2024.

The deal adds to the US Open’s growing commercial portfolio, having landed a five-year partnership with wearable tech firm Oura, which will serve as an official sponsor and wearable fitness device partner of the USTA and tournament.

Earlier this year, the USTA also announced a multi-year tie-up with law-focused AI platform Harvey, which was named the tournament’s official legal assistant partner.
