Williams replaces Santander with Barclays as banking partner for 2026 F1 season

Williams has concluded its partnership with Spanish bank Santander, a sponsor closely linked to driver Carlos Sainz, and has named British banking giant Barclays as its new official banking partner for the 2026 Formula 1 season. The change comes as Williams builds on a resurgent 2025 campaign and prepares for the sport's major regulatory overhaul.

Why it matters:

Sponsor stability is a critical component of a team's financial health and long-term planning, especially with the costly 2026 regulation changes on the horizon. Losing a partner like Santander, which followed Sainz from Ferrari, could have been a setback, but securing a replacement of Barclays' stature so swiftly demonstrates Williams's commercial momentum and provides crucial resources for its competitive ambitions.

The details:

• The partnership with Santander, announced in December 2024 alongside Sainz's first Williams test, lasted just over a year. The bank had previously sponsored Ferrari during Sainz's tenure there.
• Sources indicate Santander is not seeking a partnership with another team, instead choosing to focus its F1 investment on its role as a race sponsor for eight Grands Prix in 2026, including both Spanish rounds.
• Barclays enters the sport for the first time through this multi-year deal with Williams. Team Principal James Vowles stated the partnership is key to "seizing the opportunities of the new era" as the team invests for long-term success.
• The sponsor shift occurs as Williams enjoys an upward trajectory, having finished fifth in the 2025 constructors' championship—its best result since 2017—with Sainz securing two podium finishes.

What's next:

The immediate focus for Williams is integrating Barclays and leveraging the new partnership throughout the 2026 season. For Santander, its F1 presence continues through its extensive race sponsorship portfolio. The sponsor change underscores the dynamic nature of F1's commercial landscape, where driver movements and team performance directly influence partnership portfolios. Williams will hope its on-track progress continues to attract and retain major brands as it aims to climb higher in the standings.
