In a shocking twist ahead of the highly anticipated F1 2026 season, Williams has severed ties with Santander, the financial powerhouse that has been a stalwart sponsor of Carlos Sainz. This unexpected split comes as Sainz gears up for his second full year with the Grove-based team following a commendable performance in 2025, where he clinched two podium finishes in Azerbaijan and Qatar, propelling Williams to a remarkable fifth place in the constructors’ standings—their best outcome since 2017.
This dramatic change in sponsorship dynamics marks the end of a relationship that began when Santander followed Sainz from Ferrari, where they had supported him from 2022 to 2024. The Spanish bank had forged a multi-year partnership with Williams in December 2024, coinciding with Sainz’s first test drive for the team in Abu Dhabi. However, it appears that Santander is now shifting its focus, with insiders revealing that the bank is not pursuing partnerships with rival teams, but rather concentrating on sponsoring a series of races in the upcoming season.
In a strategic move, Williams has announced Barclays as their new official banking partner for 2026, officially concluding their partnership with Santander. Barclays is set to enhance its prominence within the sport, as Stephen Dainton, president of Barclays Bank PLC, expressed excitement over the collaboration, stating, “Our partnership with Atlassian Williams F1 Team will deepen our client engagement and elevate our brand across our key markets.” He emphasized the unique global visibility that comes with partnering one of F1’s most legendary teams.
As Santander shifts its sponsorship strategy, it will continue to back eight races in the F1 calendar, including key events in Spain, the UK, Mexico, Brazil, and the United States. A spokesperson for Santander reflected on the partnership with Williams, thanking the team for their professionalism and commitment over the past year, while wishing them success in their future endeavors.
In a world where sponsorship deals can make or break a team’s fortunes, this development raises questions about the financial landscape of Formula 1 and the implications for both Williams and Sainz as they prepare for the new season. With a promising driver lineup featuring both Sainz and Alex Albon, Williams is poised for a potential resurgence, but the loss of a major sponsor like Santander could pose challenges ahead.
As the motorsport community watches closely, Williams team principal James Vowles remains optimistic, stating that the partnership with Barclays will help the team capitalize on significant regulatory changes on the horizon, aiming for long-term success. With a storied history and a renewed vision, the upcoming 2026 season promises to be an exciting chapter for Williams—one that fans and pundits alike will be eager to follow closely.
