McLaren Racing CEO Zak Brown submitted a formal letter to FIA President Mohammed Ben Sulayem requesting rule changes that would prohibit common ownership structures across multiple Formula 1 teams. The filing arrives as F1 separately drafts restrictions on immediate staff transfers between competing teams, following a series of high-profile technical and leadership departures in the paddock.
The letter targets scenarios where a single entity or investor group controls stakes in more than one constructor. Brown's language frames the issue as competitive integrity—shared ownership creates asymmetries in car development, data access, and sponsor conflicts that the existing governance framework does not address. No specific ownership structure was named in public summaries, but the timing follows years of private equity activity across the grid and the ongoing sale processes at Alpine and Williams, where consortia with cross-team exposure have circulated term sheets.
The governance gap matters because the 2026 power unit regulations reset technical hierarchies. Teams with dual ownership exposure could theoretically optimize one program at the expense of another, or conduct parallel R&D streams that dilute the cost cap's intent. Sponsors paying $25M-plus annually for primary branding expect clean separation; shared ownership muddies exclusivity clauses and complicates category conflicts when a backer appears on two liveries. The FIA's Sporting Code does not currently define ownership thresholds that trigger conflict-of-interest reviews, leaving enforcement to case-by-case interpretation.
F1's simultaneous effort on staff transfers addresses a different friction: senior personnel moving between teams and immediately applying proprietary knowledge. The proposed rule would impose waiting periods before departed engineers, strategists, or technical directors can join direct competitors. Recent examples include the migration of aerodynamics leads and performance directors between midfield teams, and the 2024 departure of a major powertrain executive to a rival manufacturer. The intellectual property exposure is acute in Formula 1 because design cycles compress into eight-month windows and CFD allocations reward institutional memory. A chief designer who leaves in March carries correlation maps and suspension philosophies that take rivals years to develop independently.
The staff transfer curbs will likely mirror cooling-off periods used in other engineering industries, ranging from six months for junior technical roles to 18 months for senior leadership. Enforcement mechanisms remain under discussion—teams want financial penalties for poaching, while driver managers and engineer agents argue that restrictive covenants limit career mobility in a paddock with only ten employers. The FIA will present draft language at the June 2025 World Motor Sport Council meeting in Geneva, with implementation targeted for the start of the 2026 season.
Brown's ownership letter and F1's transfer restrictions are separate workstreams but share a root concern: the cost cap era compresses competitive windows, and teams are protecting marginal advantages by tightening perimeter defenses. The budget ceiling at $135M per season forces constructors to choose between personnel retention and development velocity. Losing a technical director mid-cycle can cost two-tenths per lap in the following season as replacement staff recalibrate tools and philosophies. Shared ownership structures, meanwhile, create information leakage risks that no internal compliance wall fully contains when the same ultimate beneficial owner sees both teams' financial models and staffing plans.
The commercial tension extends to team valuations. Family offices and sovereign vehicles circling Alpine and Williams are modeling enterprise values between $800M and $1.2B depending on future prize money and cost cap appreciation. Buyers want portfolio optionality—the ability to hold stakes in multiple teams if returns justify it. Brown's letter would foreclose that strategy, forcing single-team concentration and reducing buyer competition. That dynamic benefits incumbent owners at McLaren, Mercedes, and Ferrari who want scarcity to support valuations north of $2B in a sport where only ten franchises exist and the FIA has shown no appetite for grid expansion beyond the rejected Andretti bid.
Watch for FIA technical working group minutes in April 2025 where staff transfer cooling-off periods will be stress-tested against real scenarios. Also watch Alpine's sale process—expected to conclude by May 2025—where bidder structures will clarify whether common ownership appetite persists despite Brown's public pressure. And watch for paddock conversations around the Monaco Grand Prix in late May, where team principals and FIA officials hold private governance sessions that often preview regulatory shifts six months before formal announcements.
The convergence of ownership restrictions and transfer curbs signals that F1's institutional memory is now a tradable asset class, and the paddock is building moats.
The takeaway
McLaren's FIA filing on ownership rules and F1's staff transfer curbs both aim to protect competitive IP as cost cap compression raises the value of institutional knowledge.

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.
