McLaren CEO Zak Brown sent a formal letter to FIA President Mohammed Ben Sulayem this week requesting immediate rule changes to prohibit common ownership structures across multiple Formula 1 teams. The communication, confirmed by three paddock sources, arrives as ownership patterns shift beneath the $135 million annual budget cap and sponsors begin pricing governance risk into renewals.
Brown's letter does not name specific entities but addresses what McLaren legal characterizes as "structural ambiguities" in the current sporting regulations. Under existing FIA statutes, team ownership concentration is governed by Article 5.5 of the International Sporting Code, which requires competitive independence but lacks bright-line ownership percentage thresholds. The gap matters because two categories of investors now circle the grid: sovereign wealth platforms seeking portfolio exposure across multiple entries, and private equity shops assembling roll-up structures around technical partnerships. Brown's intervention suggests McLaren views the former as imminent rather than theoretical.
The timing is not coincidental. Formula 1's enterprise value has doubled since Liberty Media introduced the budget cap in 2021, pushing franchise implied values past $1.8 billion for podium-contending operations. That compression makes multi-team stakes attractive to allocators who previously dismissed single-team exposure as subscale. Two family offices with Middle Eastern LP bases have held preliminary talks with three teams in the past six months, according to advisors briefed on the outreach. None progressed to term sheets, but the conversations established valuation frameworks that assume cross-team synergies in hospitality, sponsor activation, and technical supplier negotiation—the exact efficiencies Brown's letter seeks to foreclose.
What McLaren fears is not theoretical collusion but structural slippage in competitive tension. If a single ownership group controls 20 percent stakes in three teams, those entries face pressure to optimize portfolio returns rather than individual constructor standings. The edge cases write themselves: engine supply priorities during a parts shortage, aero data sharing masked as supplier convergence, coordinated driver market strategies that disadvantage independent rivals. Brown has spent eighteen months positioning McLaren as the grid's governance hawk; this letter converts that posture into regulatory pressure on Ben Sulayem, who faces reelection scrutiny in December and needs team principal consensus on governance reforms.
The FIA's response options are narrow. Amending Article 5.5 requires World Motor Sport Council approval, which means 26 member federation votes and material lead time before the 2026 regulatory cycle. A faster path runs through the Formula 1 Commission, where teams hold veto power but Liberty Media controls agenda sequencing. Liberty has stayed publicly neutral on ownership concentration, but three strategy-group participants say the commercial rights holder views diversified investor bases as stabilizing—particularly if geopolitical risk pushes sovereign funds toward racing as soft-power infrastructure. That creates a quiet tension: Brown needs FIA rule changes, but Liberty can slow-walk Commission calendar slots if it views ownership flexibility as a liquidity feature rather than a governance bug.
Brown's letter also exposes McLaren's own structural vulnerability. The team is 100 percent owned by Bahrain's Mumtalakat sovereign wealth fund, which has explored hospitality and activation partnerships with two other teams in the past year. Those conversations never touched equity stakes, but they established commercial overlap that rivals could weaponize if McLaren pushes ownership purity too hard. One team principal, speaking off-record at the last strategy group meeting, noted the irony: "Zak wants minority stakes banned while his majority owner runs a portfolio diversification mandate." The comment did not appear in meeting minutes but circulated widely enough to reach three sponsor renewals teams by end of week.
What to watch: The FIA publishes World Motor Sport Council agendas 45 days before each session; the next window closes in early June. If ownership reform appears, expect immediate sponsor calls to team CFOs pricing governance into activation ROI models. Also watch December's FIA presidential election—Ben Sulayem needs team principal endorsements, and Brown just handed him a wedge issue that splits sovereign-backed entries from independent operators. Finally, monitor which teams join McLaren's position publicly; silence from Red Bull, Ferrari, and Mercedes would signal they view ownership flexibility as optionality worth preserving.
Brown's letter will not kill multi-team ownership structures, but it does reset the price: anyone assembling cross-grid stakes now factors regulatory risk into basis. That raises hurdle rates, narrows the buyer pool, and shifts leverage back to sellers in any near-term processes. The grid just got harder to consolidate, which was always the point.
The takeaway
McLaren's ownership rule push forces FIA to choose between governance purity and investor flexibility as sovereign funds circle multi-team stakes.

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.
