At least half a dozen billionaires have left CaliforniaCalifornia governor Gavin Newsom during an interview in San Francisco, California, Jan 29, 2026. “The impact of a one-time tax does not solve an ongoing structural challenge,” Newsom said Thursday at a Bloomberg event in San Francisco. Newsom has said he supports a national wealth tax in principle but hasn’t made a specific proposal. Google co-founder Sergey Brin, a longtime friend of Newsom’s, has taken steps to leave California and has been linked to a recent Nevada mansion purchase. As for whether the wealth tax will make the ballot, Newsom said he was unsure.
