McLaren's Zak Brown Files FIA Complaint Targeting Multi-Team Ownership Models

McLaren Racing CEO Zak Brown submitted formal correspondence to FIA President Mohammed Ben Sulayem requesting rule amendments to prohibit common ownership or control of multiple Formula 1 teams. The letter, filed directly with the governing body, argues that overlapping ownership threatens competitive integrity and creates conflicts unavailable under current sporting regulations.

Brown's move arrives as the grid prepares for two structural changes: Audi's 2026 factory entry through a majority stake in Sauber, and the lingering question of whether Andretti Global's application will resurface after Liberty Media's earlier rebuff. The timing is not subtle. Brown has spent 18 months consolidating McLaren's position as F1's third force—four podiums in the last six races, Lando Norris signed through 2027, a new technical campus in Woking absorbing £185 million in capital outlays. He is now moving to lock the regulatory perimeter before someone with deeper pockets tries to own two entries at once.

The letter does not name specific parties, but the concern is clear enough. Red Bull operates two teams—Red Bull Racing and AlphaTauri (soon RB)—under a shared ownership structure dating to 2005, grandfathered through regulatory evolution. That arrangement has drawn periodic scrutiny, particularly when AlphaTauri appears to function as a driver academy and aerodynamic testing bed rather than a truly independent competitor. Brown's argument is that no future ownership should replicate that model, and that the FIA should codify the prohibition before a Saudi sovereign fund, a Chinese automaker, or a consortium with ambitions in both powertrain supply and team operations decides two seats at the table are better than one.

The regulatory gap is real. Current F1 governance permits overlapping ownership provided teams maintain separate management, independent design operations, and comply with cost-cap audits. But "independent" is a term of art. If the same beneficial owner controls two teams, they control driver development pipelines, wind-tunnel allocation strategies, and the political bloc votes that determine everything from calendar expansion to sprint-race formats. Brown's letter essentially asks the FIA to treat team ownership like media rights: exclusive, non-overlapping, and subject to advance approval.

For sponsors and team investors, the implications are straightforward. If the FIA adopts Brown's proposal, future acquisitions become binary: one team, full control, no portfolio hedging. That raises the floor price for entry and eliminates the strategy of buying a backmarker for data access while running a flagship team for podiums. It also clarifies valuation conversations. McLaren is not for sale, but the market has been pricing teams assuming optionality—what if a buyer wants Haas for $850 million and also keeps a stake in Alfa Romeo? Brown is trying to collapse that optionality into a hard either-or.

The FIA's response timeline is unclear. Ben Sulayem's presidency has oscillated between aggressive governance interventions—banning jewelry in cockpits, threatening point deductions for procedural violations—and studied inaction on larger structural questions. The commercial-rights holder, Liberty Media, has its own views. Liberty likes competitive balance and narrative tension, but it also likes new investors and the valuation lift that comes from billionaires bidding against each other. A strict no-common-ownership rule makes the club smaller and the entry price higher, which Liberty will tolerate only if it believes the trade-off is worth the governance optics.

What to watch: FIA World Motor Sport Council meetings over the next 90 days, particularly any amendments to the International Sporting Code's conflict-of-interest provisions. Also, whether Andretti resurfaces with a cleaner ownership structure now that the regulatory window may be narrowing. And finally, who else writes a letter—Gene Haas, Lawrence Stroll, or Toto Wolff all have reasons to either support or oppose a common-ownership ban, depending on their own succession planning.

Brown is not drafting letters for sport. He is drafting them because McLaren's competitive resurgence has given him the credibility to set terms, and because he knows the next 18 months will determine whether F1's ownership landscape looks like the Premier League or the NBA. The difference is whether the same name appears twice on the entry list.
