Google cofounder Sergey Brin has emerged as the biggest financial opponent of California’s proposed billionaire wealth tax, contributing more than $100 million to campaigns against the measure. Because public records from the Nevada Secretary of State’s office show he changed his voter registration to Nevada on December 10, the irony, Forbes noted, is that Brin himself will not get a say at the ballot box.
However, the tech billionaire will not be eligible to vote on the proposal next month after changing his voter registration from California to Nevada, according to a Forbes report. Brin has channelled his opposition to the tax through his Build a Better California PAC, making him the largest donor fighting the initiative.
Brin’s relocation appears to be part of a broader effort to avoid the proposed tax, which would apply only to California residents as of January 1, 2026, according to Forbes. Forbes reported that Brin’s Google cofounder Larry Page has likewise moved away from California, although he is not yet registered to vote in Florida, according to records reviewed by the publication.
“I fled socialism with my family in 1979,” he told The New York Times in April, adding that he does not want California to end up in the same place. Former Google CEO Eric Schmidt and PayPal cofounder Peter Thiel have also donated to groups opposing the measure. Brin has likened the proposal to the socialist society he left behind.
