The FIA is internally divided on whether to permit multi-team ownership in Formula 1, according to recent statements from governing body leadership, while Christian Horner is widely expected to return to the grid by 2026 following his departure from Red Bull Racing. The timing is not coincidental.

McLaren CEO Zak Brown has sent a formal letter to FIA President Mohammed Ben Sulayem urging rule changes that would explicitly prohibit common ownership structures across multiple teams. The move follows growing speculation that Horner, who left Red Bull after fourteen years and six constructors' championships, could pursue an ownership or team principal role elsewhere on the grid. Brown's letter argues that allowing shared ownership would compromise competitive integrity and erode the independent governance structures that underpin F1's commercial model. The FIA has not yet responded publicly, but sources familiar with the deliberations indicate leadership is split between those who view multi-team holdings as a natural evolution of motorsport ownership and those who see it as existential risk to the sport's franchise value.

The governance question matters because the grid is already showing consolidation pressure. Andretti's protracted entry battle demonstrated how tightly the current ten teams guard their commercial share of F1's revenue pool, which exceeded $3.2 billion in 2024. If multi-team ownership were permitted, family offices and sovereign funds sizing grid stakes would immediately reassess valuations. A $1.5 billion minority position in a single team carries different risk than the same capital deployed across two teams with shared technical resources and sponsorship leverage. The FIA's internal split suggests no consensus exists on how to price that optionality, which means the rulebook remains open to negotiation. Brown's letter is a pre-emptive strike.

Horner's expected return adds a personnel dimension. He left Red Bull in March after an internal governance review that was never fully detailed in public filings, but which coincided with tensions over the team's 2026 power unit development and budget cap compliance. His next role will signal whether F1's labor market for senior leadership is tightening or fragmenting. If Horner joins an existing team as principal, it suggests the grid's operational talent is concentrating at the top. If he takes an ownership stake in a smaller outfit, it indicates capital is hunting for asymmetric bets on the 2026 regulation reset. Either outcome has implications for how sponsors and technical partners allocate budgets across the grid.

Meanwhile, the FIA's governance paralysis creates a window. If Brown's letter forces a formal vote before mid-2025, any prospective multi-team buyer loses the ambiguity that makes the play attractive. If the FIA delays, families and funds will continue quiet diligence on minority stakes in Alpine, Williams, and Haas, knowing the rules could shift in their favor. The $200 million anti-dilution fee for new entrants remains in place, but existing teams can be acquired without triggering that cost, which makes consolidation the cheaper path to grid expansion.

Watch for FIA World Motor Sport Council minutes in the next sixty days, which will indicate whether Brown's letter prompted a formal review. Horner's next paddock appearance, likely at the Canadian Grand Prix in June, will clarify whether his 2026 return is as team principal or owner. And any Alpine or Williams minority stake announcement before the summer break would confirm that capital is moving faster than governance.

The FIA's division is not a bug. It is the market working.
