Could Horner Buy Mark Walter’s Cadillac F1 Stake Amid TWG Financial Pressure? – Christian Horner has been linked with several possible routes back into Formula 1 since leaving Red Bull in 2025. Now, following Mark Walter’s decision to sell his controlling stake in the Los Angeles Lakers for a record $12.5 billion, speculation is inevitably turning towards another major sports asset controlled by Walter: Cadillac F1.
There is no evidence that Horner is currently negotiating to buy Walter’s stake in Cadillac, and TWG Global has previously rejected suggestions that it is considering selling the Formula 1 team. However, the financial pressure surrounding Walter’s wider business empire has created a situation in which further asset sales cannot be completely ruled out.
That distinction is important. The possibility of Horner becoming involved with Cadillac is currently a scenario rather than a reported deal.
Mark Walter’s Lakers sale puts TWG assets under the microscope
Walter’s decision to sell his controlling interest in the Lakers just 14 months after acquiring it has intensified scrutiny of his wider investment empire.
The Lakers deal values the NBA franchise at $12.5 billion, compared with the approximately $10 billion valuation attached to Walter’s acquisition in 2025. The transaction with Josh Kushner and former Disney CEO Bob Iger still requires the necessary NBA approvals.
The timing is significant because Walter and businesses connected to his TWG Global empire are facing a federal investigation involving loans made by insurers he controls.
Reuters reported on August 18 that Delaware Life intends to replace up to $6.5 billion of investments linked to Walter’s business interests with equivalent unaffiliated assets as the company responds to regulatory concerns. The wider investigation involves allegations surrounding the disclosure and classification of related-party transactions. No charges have been filed against Walter.
Bloomberg has also reported that TWG Global has approached investment firms about raising capital and has been considering different ways of addressing the loans on its insurers’ books.
The Lakers sale therefore matters to Formula 1 not because Cadillac is known to be for sale, but because it demonstrates that Walter is prepared to dispose of highly valuable sports assets when the circumstances demand it.

Could Cadillac become another asset for sale?
Cadillac is particularly interesting because TWG Global holds the majority stake in the Formula 1 operation alongside General Motors.
The team made its competitive debut in 2026 as Formula 1’s 11th constructor, with Ferrari supplying its initial power units before GM’s own power-unit programme becomes part of the project.
TWG itself has publicly presented Cadillac as a long-term strategic investment. Its own material surrounding the team has stressed the ambition to build a successful operation rather than simply occupy a place on the grid.
There is also no indication that Cadillac itself has been implicated in the investigation surrounding Walter’s financial empire.
That makes the distinction between financial pressure on an owner and financial problems at the F1 team particularly important.
Andretti Lawsuit adds further intrigue
There is also another legal thread involving the wider TWG/Andretti operation. As TJ13 previously reported, Michael Andretti became involved in legal action surrounding his former racing organisation after TWG Global took control of Andretti Global and the project ultimately evolved into Cadillac F1.
That dispute is separate from the current investigation into Walter’s financial interests, and neither Cadillac F1 nor Andretti Global has been accused of wrongdoing in connection with that investigation.
Nevertheless, a Formula 1 team represents a potentially valuable asset. The sport’s commercial growth has pushed team valuations dramatically higher in recent years, while Cadillac’s position as an American manufacturer-backed project could make its ownership stake particularly attractive to prospective investors.
If Walter ultimately needed to raise additional capital, an equity sale could theoretically become one option.
But that remains hypothetical.
Why Christian Horner suddenly becomes an intriguing name
This is where Christian Horner enters the story.
The former Red Bull team principal has made little secret of his desire to remain connected with Formula 1 following his departure from Red Bull in July 2025.
Horner has already been linked with several possible projects.
In January, Formula 1 confirmed that Horner was part of a group of investors interested in acquiring a stake in Alpine. Alpine subsequently confirmed that preliminary discussions had taken place over the sale of the 24% stake held by Otro Capital.
Horner has also been connected with discussions involving Chinese automotive giant BYD over a potential future F1 project. Reuters reported in June that BYD was exploring ways of entering Formula 1, although sponsorship was considered a lower-risk route than creating an entirely new team.
Horner subsequently returned to the F1 paddock at Silverstone and acknowledged the speculation surrounding his future.
“There’s just so much speculation. I think I’ve been going to every team on the grid so far. I’m just here to enjoy the race,” Horner said, according to Motorsport Week.
That quote perhaps explains why the Cadillac theory needs to be treated carefully.
Horner has been linked with numerous opportunities because he remains one of the most experienced available figures in Formula 1. That does not mean every rumour represents an active negotiation.
Horner has the experience, but the numbers would be enormous
If Walter’s Cadillac stake ever did become available, Horner would theoretically bring qualities that could make him attractive to an investor group.
He spent more than two decades running Red Bull Racing and helped transform the team from a midfield operation into one of Formula 1’s dominant forces.
However, buying into Cadillac would be a very different proposition from returning as a team principal.
The financial requirement would likely be substantial, potentially requiring Horner to assemble a consortium or investment partnership rather than personally fund an acquisition.
There would also be the question of General Motors.
GM is not simply a commercial partner. Cadillac’s long-term F1 strategy is tied to the manufacturer’s wider automotive programme, including its planned power-unit involvement. Any significant change in TWG’s ownership position would therefore need to fit with GM’s strategic interests.
A prospective buyer would also have to satisfy Formula 1 and FIA requirements, while any transaction involving a significant team stake would need to comply with the sport’s commercial agreements.
In other words, even if Walter decided to sell, a Horner-led acquisition would not be straightforward.
The December question could become crucial
The most important development may therefore not be whether Horner has been linked with Cadillac, but whether Walter’s financial circumstances force TWG Global to consider additional disposals.
The Lakers transaction provides Walter with a substantial injection of capital, while Reuters has reported that Delaware Life is already restructuring billions of dollars of related investments.
At the same time, reports have indicated that Walter’s stake in Chelsea could also be the subject of discussions.
For Cadillac, however, the official position remains unchanged.
There is currently no confirmed sale process involving the F1 team and no confirmed approach from Horner to purchase Walter’s interest.
That means headlines suggesting Horner is about to take control of Cadillac would go considerably beyond the available evidence.
Yet the circumstances make the subject worth watching.
Walter has demonstrated with the Lakers that ownership of even the world’s most prestigious sporting properties is not necessarily permanent. Meanwhile, Horner is actively exploring routes back into Formula 1 and has already been involved in discussions surrounding team ownership.
If another major TWG asset were eventually placed on the market, Cadillac could attract considerable attention.
And if Horner is genuinely determined to return to F1 in an ownership or investment capacity, a stake in an existing team could provide a much quicker route than attempting to establish a completely new constructor.
For now, however, Christian Horner buying Mark Walter’s Cadillac stake remains speculation rather than a reported transaction.
The more immediate story is the financial pressure surrounding Walter’s wider empire and whether the $12.5 billion Lakers sale proves to be the beginning, rather than the end, of a broader restructuring of his sports portfolio.
If that process reaches Formula 1, Horner could suddenly become a very interesting name.
