- Mark Zuckerberg made a deal with Meta's board to help him pay a proposed California tax on billionaires without losing his ownership stake in the company he founded, according to regulatory filings published this week.

If passed by voters in the Nov. 3 election, the measure would levy a one-time 5% tax on the wealth of Californians whose net worth exceeds $1 billion.

Zuckerberg is the sixth-richest person in the world with a net worth estimated at more than $220 billion, according to Forbes.
