Quick Summary
An entity linked to Google cofounders Sergey Brin and Larry Page moved out of California at the end of 2025. The move occurred shortly before a proposed wealth tax targeting the state's richest residents.
T-Rex LLC converted into a Delaware-based entity on December 24, 2025. The proposed tax would require residents with assets exceeding $1 billion to pay a one-time 5% tax. If approved by voters in November, the tax would apply retroactively to the beginning of the year.
The T-Rex LLC Conversion
An entity tied to Sergey Brin and Larry Page moved from California to Delaware in late December. T-Rex LLC, formed in 2006, converted into a Delaware LLC called T-Rex Holdings on December 24, 2025. This conversion was documented in a California filing.
Prior filings over the past 20 years listed Brin and Page as managers of the LLC at a Palo Alto address. In the conversion filing, T-Rex Holdings listed an address in Reno, Nevada as its principal office. Brin and Page remain managers of the entity.
The filing describes T-Rex Holdings as a "management company." Like other ultrawealthy executives, Brin and Page have used LLCs as flexible vehicles to hold assets or manage investments. The LLC's name may be a reference to a bronze T. rex statue at Google's headquarters in Mountain View.

California's Proposed Wealth Tax
The move comes as California's wealthiest residents weigh whether to leave the state. A proposed ballot measure would make roughly 200 residents whose assets exceed $1 billion pay a one-time 5% tax. The measure attempts to address a projected multibillion-dollar state budget deficit.
If the proposal receives enough signatures, it will appear on the state ballot in November. If approved by voters, it will apply retroactively for residents living in California as of January 1, 2026. To avoid the tax, individuals would need to have been out of the state by the end of December 2025.
California law determines residency based on a variety of factors, including time spent in the state and any substantial business dealings. A letter from celebrity attorney Alex Spiro to California Governor Gavin Newsom urged the governor to stop the proposed tax.
Broader Relocation Trends
Larry Page recently severed ties with California by converting his family office out of the state and incorporating it in Delaware. He has also incorporated other entities in Delaware, including a vehicle used to fund influenza research and another for his flying car ventures. Sergey Brin is associated with several other entities in California, including the Sergey Brin Family Foundation and Bayshore Global Management.
Page and Brin are, respectively, the second and fourth-richest people on the planet, according to the Bloomberg Billionaires Index. Each has a net worth exceeding $250 billion. After stepping back from executive roles in 2019, Brin has returned to hands-on work at Google, while Page remains a controlling shareholder outside daily operations.
Conclusion
The conversion of T-Rex LLC highlights the financial strategies employed by the world's wealthiest individuals in response to potential tax legislation. As the proposed wealth tax moves toward a potential vote in November, the decisions of Brin and Page serve as a significant indicator of the concerns held by California's high-net-worth residents. The outcome of the ballot measure will likely influence future residency and investment decisions within the state.
