Fenway Sports Group Eyes Cadillac F1 Takeover at $3B+ Valuation Amid DOJ Probe

Fenway Sports Group, the private holding company controlling Liverpool FC and the Boston Red Sox, is conducting due diligence on a potential acquisition of the Cadillac Formula 1 team, according to sources familiar with the discussions. The talks value the operation north of $3 billion, though the exact structure remains fluid as federal investigators continue examining related entities.

The timing is precise. General Motors announced Cadillac's F1 entry in November 2023, joining the grid for the 2026 season alongside Andretti Global. That partnership fractured publicly six weeks ago when Liberty Media rejected Andretti's bid, leaving Cadillac's path forward murky. Fenway entered talks in mid-February, shortly after the Andretti rejection became final. The DOJ opened a separate antitrust inquiry into Formula 1's team entry process three weeks later, naming no targets but requesting documents from Liberty Media, the FIA, and at least two existing team principals.

For Fenway, the calculus is institutional appetite. John Henry's group manages $10 billion in sports assets, including LeBron James as a Liverpool minority holder and partnerships across MLB, NHL, and NASCAR properties. Formula 1 represents the only major global motorsport without a Fenway footprint. The U.S. market now supports three F1 races—Miami, Austin, Las Vegas—generating $1.2 billion in combined economic impact in 2024. Cadillac's manufacturing presence in Michigan and Tennessee offers sponsor alignment Fenway's existing portfolio lacks: automotive OEMs, industrial suppliers, Midwest corporate hospitality budgets.

The complication is Michael Andretti. His ownership stake in the proposed Cadillac team remains undefined publicly, but sources place it between 18% and 28%. Andretti has not returned calls from Fenway representatives since late February, according to one person briefed on the outreach. His silence extends to GM executives, who are operating under the assumption that any Fenway deal requires Andretti's exit. That triggers the question of valuation: Andretti's stake was worth roughly $400 million at the rejected Liberty bid's implied price. A forced sale at distressed terms invites litigation. A negotiated buyout at premium invites DOJ scrutiny over whether the transaction was structured to circumvent the original rejection.

Liberty Media's position is strategic patience. The commercial rights holder collected $3.2 billion in revenue in 2024, up 11% year-over-year, driven largely by U.S. broadcast and hospitality growth. Adding an 11th team dilutes the existing 10-team revenue pool by roughly 9% per entrant unless the new franchise pays a dilution fee. Liberty set that fee at $600 million for Andretti, who balked. Fenway has not formally accepted that figure but has indicated willingness to negotiate in the $450 million to $550 million range, contingent on commercial terms around sponsorship exclusivity and U.S. race weekend paddock access.

Watch for three pressure points. First, the DOJ's document production deadline expires April 18. If subpoenas follow, Fenway's appetite for a contested entry process will be tested. Second, Cadillac's engine supply agreement with Ferrari runs through 2028 as a customer, then transitions to a GM-built power unit in 2029. That $1.8 billion R&D commitment is already budgeted, but any ownership change resets partnership terms with the Scuderia. Third, Andretti's IndyCar operation announced a title sponsor renewal with DHL on March 3, suggesting his racing focus is shifting back to North America. If he exits F1 cleanly, expect a statement within 30 days.

The tell will be paddock sightings. Fenway executives attended the Miami Grand Prix in May 2024 as guests of McLaren. If they appear in Bahrain on March 14 without a McLaren host, the diligence is moving to term sheets.
