Silicon Valley Billionaires Launch $87 Million Ad Blitz Against California Wealth Tax
A coalition of billionaires, including Sergey Brin, has reserved about $87 million in California ad time to oppose Proposition 40, a proposed one-time wealth tax on residents with a net worth of $1 billion or more. The advertising campaign, set to begin next month, marks a high-profile clash over the measure and underscores the influence of Silicon Valley wealth in state politics as some billionaires have already relocated or spent heavily in related campaigns.
