A significant financial battle is unfolding in California, as the state’s wealthiest residents are channeling considerable resources into defeating a proposed one-time tax on their net worth. This measure, Proposition 40, seeks to impose a 5% tax on individuals with assets exceeding $1 billion, with the proceeds earmarked for healthcare funding. The opposition campaign has quickly amassed a substantial war chest, reflecting the intense concern among those who stand to be directly impacted by such a levy.
Recent campaign finance filings reveal a surge in contributions to Building a Better California, a political action committee established specifically to oppose Proposition 40. Venture capitalist John Doerr, whose net worth is estimated at $22.6 billion, recently committed $7.5 million to the group. Following closely, Chris Larsen, executive chair of blockchain company Ripple and an individual with an estimated $11.4 billion fortune, added another $10 million to the PAC’s funds. These contributions are part of a broader effort that has seen the committee’s endowment swell to $110 million by late June, indicating a serious commitment to influencing the November ballot outcome. Other notable donors include John Hering, co-founder of cybersecurity firm Lookout, who contributed $946,000, and Neil Mehta, founder of Greenoaks Capital, with a $250,000 donation.
Despite the considerable financial push from opponents, public opinion remains divided. A recent survey conducted by UC Berkeley’s Institute of Governmental Studies found that 48% of likely voters support the billionaire tax, while 41% are against it. The poll, which surveyed over 4,000 registered voters, highlighted a partisan split: registered Democrats largely favor the proposal, while 80% of Republicans oppose it. Crucially, unaffiliated voters showed only 50% support, suggesting that the outcome will hinge on their sway. Eric Schickler, co-director of the Institute of Governmental Studies, noted that the initiative is shaping up to be a closely contested race, with opponents needing to make inroads among the state’s traditionally Democratic-leaning electorate.
In a multi-pronged strategy, Building a Better California has also backed two counter-initiatives, Proposition 41 and Proposition 42. Should either of these receive more votes than Proposition 40, they would effectively nullify the billionaire tax, even if the tax itself passes. Proposition 41 proposes requiring a state auditor review of any special tax proposal before it reaches voters, while Proposition 42 aims to ban new taxes based solely on asset ownership, a departure from the typical practice of taxing assets only upon sale. Awareness of these counter-measures remains low, with fewer than a third of voters familiar with them, compared to 72% who know about the billionaire tax. The PAC has further committed an estimated $87 million for advertising time leading up to the November election, a substantial investment aimed at shaping public perception.
The debate has drawn in prominent political figures and industry leaders. While Governor Gavin Newsom and Democratic gubernatorial candidate Xavier Becerra have expressed opposition to Proposition 40, the California Democratic Party recently endorsed the proposal, presenting a challenge for the tax’s opponents. Among the most vocal critics is Google co-founder Sergey Brin, who has reportedly moved significant assets out of California and contributed an additional $20 million to Building a Better California, bringing his total opposition funding to $102 million. Mark Cuban, the entrepreneur and investor, also weighed in, cautioning that such a tax could deter entrepreneurs and innovation in the state, a sentiment he shared in an exchange with Congressman Ro Khanna on X.
Conversely, national figures like Senator Bernie Sanders of Vermont have championed the billionaire tax, arguing it would demonstrate that a democratic society still empowers its people. Senator Sanders, alongside Representative Khanna, introduced federal legislation in March, the “Make Billionaires Pay Their Fair Share Act,” which mirrors California’s proposal by seeking a 5% wealth tax on America’s 938 billionaires. This federal bill aims to expand Medicare, reverse Medicaid cuts, and provide direct payments to lower and middle-income households. The California ballot initiative, therefore, serves as a significant test case, with implications extending far beyond the state’s borders.
