The FIA is reviewing whether Formula 1 should permit multi-team ownership after Mercedes were linked to a minority stake arrangement, with the governing body's leadership showing no consensus on the question. The debate surfaced publicly days after McLaren CEO Zak Brown sent a formal letter to FIA President Mohammed Ben Sulayem calling for explicit rule changes to block any future common ownership structures.

The uncertainty arrives as Formula 1 franchise values climb past $2 billion per team—Aston Martin was valued near that figure in its most recent capital raise, Williams sold at $725 million in 2020 before broader valuations reset upward—and as the Concorde Agreement's current commercial distribution model runs through 2030. The Mercedes scenario involves discussions around a partial stake that would not breach existing thresholds but could test interpretive boundaries around control and conflict-of-interest provisions embedded in the Concorde framework. No formal application has been filed; the FIA is examining whether existing language covers the arrangement or whether amendments are required.

Brown's letter, circulated internally before reaching Ben Sulayem, argues that even minority cross-ownership creates incentive misalignment in a ten-team championship where constructor standings directly determine $1 billion+ in annual prize fund allocation. McLaren finished fourth in 2024, collecting approximately $140 million under the current sliding scale; a team dropping one position forfeits roughly $15-20 million depending on final order. Brown's position is that any ownership overlap—regardless of voting control—compromises competitive integrity in a sport where aerodynamic data sharing, driver loan arrangements, and wind tunnel allocation disputes already strain governance mechanisms. His letter does not name Mercedes, but timing suggests coordination with teams who view the scenario as precedent-setting.

The internal FIA split is unusual. Ben Sulayem has not publicly endorsed Brown's view, and sources indicate at least two senior FIA officials believe the current rulebook already prohibits meaningful multi-team arrangements without requiring textual changes. The disagreement is partly procedural—whether the FIA unilaterally amends Concorde annexes or whether F1 Commercial Rights Holder Liberty Media must co-sign changes—and partly philosophical. Some officials note that MotoGP permits multi-team ownership under Dorna's structure, and that European football's multi-club models operate under UEFA rules without collapsing competitive balance. The counterargument, pressed by Brown and echoed by Red Bull's Christian Horner in separate remarks, is that Formula 1's ten-team grid and fixed revenue pool make cross-ownership materially different from football's promotion-relegation pyramid or MotoGP's satellite team economics.

What matters for allocators sizing franchise stakes: regulatory clarity on ownership structure is now a 2025 diligence item. Family offices evaluating minority positions in existing teams—several are in market, none naming sellers publicly—must model scenarios where ownership rules tighten mid-hold period, either blocking future buyers or triggering forced divestitures. The FIA has not set a timeline for resolution, but the Mercedes scenario and Brown's letter create pressure to clarify rules before the 2026 power unit regulation change, when new technical partnerships and potential entry applications (Andretti-Cadillac remains in correspondence with the FIA despite F1's prior rejection) will force the question again.

Watch for three developments: whether the FIA publishes a formal interpretation of existing Concorde ownership language by mid-2025, whether Liberty Media weighs in publicly (the commercial rights holder has remained silent), and whether any team files a formal application to test the current rules. The next FIA World Motor Sport Council meeting is scheduled for June; multi-team ownership is not listed on the provisional agenda but could be added if Ben Sulayem determines the issue requires full council vote rather than executive interpretation. Brown's letter, meanwhile, is circulating among team principals, and at least one additional team is preparing supporting correspondence.

The FIA's indecision is itself a signal: the governing body does not yet have the votes or the legal clarity to move decisively, and the Mercedes scenario—still unconfirmed in structure or participants—may collapse before rules are tested. If it proceeds, the sport's ownership rulebook rewrites in real time.
