McLaren CEO Zak Brown has intensified Formula 1’s growing political battle after publicly raising concerns about Mercedes potentially acquiring a stake in Alpine. The outspoken McLaren boss has reportedly sent a detailed six-page letter to FIA president Mohammed Ben Sulayem, warning that the sport risks serious conflicts of interest if manufacturers are allowed to control or influence multiple teams on the grid.
The controversy arrives at a sensitive moment for Formula 1, with the sport already facing major debates surrounding the 2026 regulations, competitive balance, and the future direction of team ownership structures. Brown’s intervention has now pushed another explosive issue into the spotlight — whether multi-team influence threatens the integrity of Formula 1 competition.
At the center of the discussion are reports suggesting Mercedes could acquire the 24 percent Alpine stake currently owned by investment group Otro Capital. While no deal has officially been confirmed, the possibility alone has triggered strong reactions across the paddock, particularly from McLaren.
Why Zak Brown Is Concerned About Multi-Team Influence in Formula 1
Zak Brown has repeatedly voiced discomfort over close alliances between teams, but his latest move signals a major escalation. According to reports, Brown believes Formula 1 risks creating an uneven competitive environment if major manufacturers begin directly or indirectly influencing multiple outfits simultaneously.
His concerns are not limited to ownership alone. Brown reportedly highlighted several key issues, including:
Potential sharing of technical resources
Conflicts during regulatory voting discussions
Reduced restrictions on staff movement
Possibility of on-track cooperation between affiliated teams
One example Brown referenced was Daniel Ricciardo’s controversial fastest lap during the 2024 Singapore Grand Prix, which many critics believed indirectly impacted the championship battle involving Red Bull and McLaren.
For Brown, these situations create dangerous gray areas that could eventually damage Formula 1’s credibility if left unchecked.
The Red Bull and Racing Bulls Model Remains a Key Talking Point
Although Brown stopped short of directly attacking Red Bull’s long-standing structure with Racing Bulls, his comments clearly point toward concerns over Formula 1’s existing satellite-team model.
The Red Bull system has operated for more than two decades, originally beginning with Toro Rosso before evolving into Racing Bulls. Over the years, the arrangement has allowed Red Bull to develop young drivers, share strategic alignment, and maintain close operational links between both organizations.
Brown appears willing to tolerate that historical structure because it predates modern Formula 1’s current commercial era. However, his fear is that similar models could rapidly spread if new regulations are not introduced soon.
If Mercedes were to establish influence over Alpine while Red Bull continues operating Racing Bulls, rival teams without partner organizations could feel increasingly disadvantaged both politically and competitively.
FIA Under Pressure to Address a Growing Problem
FIA president Mohammed Ben Sulayem has already acknowledged that Formula 1 currently lacks clear regulations specifically addressing these types of ownership complications. That reality places enormous pressure on the governing body to act before the situation escalates further.
The challenge for Formula 1 is balancing commercial freedom with sporting fairness.
On one hand, manufacturer partnerships can strengthen struggling teams financially and technically. On the other hand, excessive collaboration risks creating a two-tier championship where independent teams are left isolated against expanding manufacturer networks.
Other major sports already regulate this issue aggressively. European football leagues and American professional sports organizations generally prohibit owners from holding significant influence over multiple competing teams precisely because of competitive integrity concerns.
Formula 1 may now be approaching a similar crossroads.
Why the Mercedes-Alpine Rumors Could Reshape the Grid
The Alpine situation is particularly intriguing because the French team has struggled for consistency in recent seasons despite significant investment. A partnership with Mercedes could potentially provide stability, technical expertise, and stronger long-term competitiveness.
However, rivals fear such relationships could also create hidden advantages behind closed doors.
Mercedes already remains one of Formula 1’s most influential manufacturers, supplying engines and maintaining deep technical resources. Any additional influence over another team could shift the balance of power dramatically — especially under the complex 2026 regulations.
This also comes during a period of major driver-market instability involving Max Verstappen, Oscar Piastri, George Russell, and several other high-profile names. Political power within Formula 1 may become just as important as outright speed over the coming years.
What Happens Next Could Define Formula 1’s Future
Zak Brown’s decision to take the issue public guarantees that the debate will not disappear quietly. Formula 1’s leadership now faces mounting pressure to establish clear rules regarding ownership structures, alliances, and manufacturer influence before more controversial partnerships emerge.
If the FIA fails to act, tensions between independent teams and manufacturer-backed organizations could intensify rapidly.
At the same time, Brown’s aggressive stance may also strengthen McLaren’s position politically within the sport. By publicly defending competitive fairness, the McLaren CEO has positioned himself as one of the leading voices pushing for stronger governance during a period of enormous transformation in Formula 1.
The timing is critical. With the 2026 era already producing massive controversy around engines, technology, and sporting direction, ownership politics could become the next major battlefield shaping the future of Formula 1.
And as discussions continue behind closed doors, one thing is becoming increasingly clear: the fight for control of Formula 1 is no longer happening only on the racetrack.
