California Billionaire Tax Battle: Ultra-Rich Spend $1M Daily to Fight 2026

California's billionaire tax battle has intensified as the ultra-rich spend over $1 million daily to defeat Proposition 40, a proposed one-time 5% wealth tax on the state's billionaires. Tech billionaires have raised more than $340 million to fight the measure, according to state financial disclosures, making it one of the most expensive campaigns in California history.

What Is California's Proposition 40?

Proposition 40, also known as the California Billionaire Tax, is a ballot measure that would impose a one-time 5% tax on the state's billionaires. The proceeds would primarily fund healthcare programs, with some allocation to education and food assistance. The measure has divided Democrats, with supporters like Senator Bernie Sanders and Congressman Ro Khanna arguing it's a necessary step to address inequality, while opponents claim it could lead to higher taxes for all Californians.

The Campaign Against the Wealth Tax

The opposition campaign, funded by tech billionaires and other wealthy individuals, is spending at a record pace. During the first 19 days of September, the campaign spent at least $21.2 million, surpassing $1 million per day. Voters are being inundated with robotexts, mailers, and advertisements warning that the tax would "expose all Californians to higher taxes."
