NFL Team Valued at $9B in OpenAI Chair Stake Sale

49ers Soar Past $9 Billion Valuation with OpenAI Chairman’s Stake Acquisition

The San Francisco 49ers have exceeded a $9 billion valuation following an agreement for OpenAI Chairman Bret Taylor to acquire a stake in the National Football League (NFL) franchise. The investment signals a growing trend of tech and private equity interest in professional sports teams.

The deal, announced Tuesday, December 9, 2025, will see Taylor – also co-founder and CEO of AI firm Sierra and former board chairman of Twitter – purchase one percent of the team, which plays its home games at Levi’s Stadium. The stake sale by the York family values the five-time Super Bowl champions at over $9 billion (£6.8 billion), positioning them as the fourth most valuable NFL franchise.

Currently, the Dallas Cowboys lead the league in valuation at $12.8 billion, followed by the Los Angeles Rams ($10.43 billion) and the new York Giants ($10.25 billion). This latest valuation underscores the escalating financial power of NFL teams.

Did you know? – The 49ers have won five Super Bowl titles,their last coming in 1995. They have a long and storied history, dating back to their founding in 1946 as part of the All-America Football Conference.

The transaction follows a similar move in September when barcelona-based investor Sixth Street acquired a minority stake in the New England Patriots, also valuing the franchise at $9 billion. “These investments demonstrate the increasing appeal of NFL franchises as stable and perhaps lucrative assets,” noted one sports finance analyst.

If approved by NFL owners on Wednesday, December 10, 2025, the sale will add to a series of minority investments in the 49ers. Pete Briger of Fortress Investment Group, Will Griffith of Iconiq Capital, Indian-american billionaire Vinod Khosla, and Leeds United co-owner Byron Deeter have all previously invested in the team for minority stakes.

Pro tip: – NFL teams are increasingly open to minority investments as a way to raise capital without relinquishing control. This allows owners to fund stadium improvements and player acquisitions.

Levi’s Stadium is also slated to host six matches during the 2026 FIFA World Cup, though the teams assigned to play there are not currently considered global football powerhouses. The stadium will host teams including Qatar, Switzerland, Austria, Jordan, Paraguay, Algeria, and Australia during the group stages, and will stage one Round of 32 knockout match.

The NFL currently limits private equity stakes in franchises to 10 percent and maintains a pre-approved list of potential investors, making minority stake sales increasingly common. In October,the league approved private equity and individual stake sales for the New York Giants,New England Patriots,and San Francisco 49ers,collectively valuing the three franchises at $29 billion.

This influx of investment highlights the growing financialization of professional sports and the appeal of NFL franchises to a diverse range of investors. The trend is expected to continue as teams seek capital for stadium upgrades, player acquisitions, and broader business ventures.
