McLaren CEO Zak Brown has sent a formal letter to FIA President Mohammed Ben Sulayem requesting elimination of regulatory pathways that permit common ownership structures across multiple Formula 1 teams. The letter, confirmed this week, revives Brown's 2024 position on team independence at a moment when grid expansion talk has returned and franchise valuations have crossed $2 billion for mid-pack constructors.
Brown's concern centers on scenarios where a single entity or related parties could hold stakes in more than one team, raising conflict-of-interest questions around strategy, driver movement, and technical collaboration. The current FIA governance framework does not explicitly prohibit shared ownership—Red Bull operates two entries, though under distinct corporate structures—but Brown's letter seeks a bright-line rule. No details on proposed thresholds or look-back periods have surfaced, but the timing suggests McLaren legal has been tracking recent paddock chatter about portfolio plays.
The letter lands as F1's commercial engine accelerates. Liberty Media's Vegas race cleared $500 million in economic impact its first year; Miami and Austin sponsorship inventory sells out eighteen months ahead. That momentum attracts non-traditional capital—sovereign funds, private equity, family offices sizing minority stakes or outright entries. Andretti's 2026 bid collapsed last year, but whispers of a second application persist, and any new slot opens valuation questions. If a billionaire or fund buys Team A at $1.8 billion, then takes a 15 percent position in Team B six months later, does that violate competitive balance? Brown's letter implies yes; the rulebook currently says maybe.
For sponsors and broadcasters, the ask matters because grid stability underwrites contracts. A $40 million annual deal assumes ten independent constructors with separate incentives. Shared ownership muddies that math: if two teams coordinate pit strategy or driver swaps, the spectacle shifts from zero-sum competition to managed outcome, and media rights buyers notice. McLaren's own sponsor pipeline—Google, OKX, Arrow—sits on multi-year commitments predicated on independent racing. Brown's letter functions as both governance push and brand-protection insurance.
The FIA has not commented on receipt or timeline. Regulatory changes of this scope require World Motor Sport Council approval, a process that stretches across quarters and involves ten member federations. Brown's move also follows his 2024 public criticism of team budget transparency and cost-cap enforcement, positioning him as the paddock's compliance hawk. That role carries risk: antagonize too many team principals, and McLaren finds itself isolated on other governance votes. But with McLaren Racing now a standalone entity under Bahrain's Mumtalakat sovereign fund—which bought out prior shareholders in 2023—Brown answers to investors who value clarity over clubhouse courtesy.
Watch for FIA acknowledgment by mid-February, likely a procedural note rather than substance. If the letter gains traction, expect counter-lobbying from Red Bull and any ownership groups exploring dual-entry structures. The next WMSC calendar session is scheduled for late March in Bahrain, one week before the season opener. By then, the 2026 engine regulations will dominate headlines, but ownership governance lingers as the longer game. Brown's letter ensures it stays on the docket, and his legal team will be watching who picks up the phone.
The takeaway
McLaren pushes FIA to ban multi-team ownership as F1 valuations climb and new capital circles the grid.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
