Quick Summary

Meta revealed in a recent SEC filing that CEO Mark Zuckerberg threatened to sell his $110 million home in Palo Alto and move out of California if Proposition 40, which would impose a 5% wealth tax on billionaires, passes. This could force him to liquidate stock worth approximately $250 billion, potentially reducing his voting interest in Meta to around 53%. Talks between Zuckerberg and the board about this issue began in July and involved discussions over how to revise his compensation agreement to provide better liquidity in case of such a large tax bill.

Story summary

Meta CEO Mark Zuckerberg has threatened to move out of California and potentially sell his $110 million home in Palo Alto if the state passes Proposition 40, a proposed 5% wealth tax on billionaires. According to a recent SEC filing by Meta, Zuckerberg expressed concerns during board meetings that such a tax could force him to liquidate significant portions of his stock, which would dilute his voting shares and control over the company he founded. Zuckerberg’s net worth is approximately $250 billion, meaning the proposed tax could amount to a bill of $12.5 billion. This filing marks the first time Meta has disclosed Zuckerberg's plans and concerns regarding Proposition 40, which voters will decide on in an upcoming election.
