Silicon Valley Tycoons Invest to Counter California Wealth Tax
California's tech and venture capital billionaires are concentrating their funding through political action committees to oppose Proposition 40, which will be voted on in November. This proposition proposes a one-time 5% wealth tax on California residents with assets exceeding $1 billion as of the beginning of the year.
Chris Larsen, co-founder of Ripple, donated $5 million to the anti-Proposition 40 group Golden State Promise, with Ripple Labs contributing an additional $5 million. Google co-founder Sergey Brin, venture capitalist John Doerr, and Palantir co-founder Peter Thiel have also been revealed to support the opposition camp.
The organization Building a Better California, supported by Brin and other Silicon Valley billionaires, has publicly opposed Proposition 40 and donated $5 million to the anti-campaign backed by teachers and firefighters' unions. This organization has raised over $156 million in total, with contributions from Brin exceeding $100 million, Doerr over $17 million, Larsen about $12 million, and former Google CEO Eric Schmidt $3 million.
The organization has spent over $127 million promoting Propositions 41 and 42: Proposition 41 requires audits of new state-level special taxes and limits their exemption spending caps, while Proposition 42 prohibits the state government from imposing new taxes on personal property, intellectual property, and retirement accounts. If Proposition 40 passes but Propositions 41 or 42 receive more votes, the wealth tax will become ineffective.
Supporters of Proposition 40 estimate that the tax could raise about $100 billion over five years, with 90% intended for healthcare and the remaining funds for food assistance and education. Supporters include the California Democratic Party, the California Labor Federation, Bernie Sanders, and Ro Khanna.
In market mechanisms, buyers are super-rich individuals with high liquidity in equities and unlisted company interests, directing funds to political action committees, election proposal design, and advertising mobilization; sellers are not financial assets but the state's right to levy taxes on potential tax bases. The event is triggered by Proposition 40; if the tax system is implemented, founders and shareholders with large paper wealth but insufficient cash flow will be under pressure; the legal, tax planning, relocation services, and lobbying industries will benefit.

Peter Thiel previously severed ties with California in 2025, ahead of the proposed wealth tax; this continues his long-standing strategy of diversifying capital, company registrations, and political resources. Brin is also reducing his official and financial ties to California. Their actions indicate that the battle over the wealth tax is not only on voting day but also occurs in the restructuring of tax residency, asset locations, and legal connections.
The capital pathway has two layers: directly, Larsen and Ripple Labs have invested a total of $10 million in Golden State Promise; indirectly, Brin, Doerr, Larsen, and Schmidt have concentrated their funding in Building a Better California, which then invests to hedge against Propositions 41 and 42 and the opposition camp. The key is not merely to defeat a tax but to create a competitive ballot design that establishes a system where "even if the tax proposal receives majority support, it may still become ineffective."
This is similar to California's Proposition 10 on local rent control in 2018, and the long-term pattern of large industry associations in the U.S. using ballot initiatives and pre-legislation to reshape regulatory boundaries: the resource-rich side often bets not only on the outcome of the main proposal but also funds alternative rules to increase their chances of success. Currently, Silicon Valley is transitioning from "high valuations creating wealth" to "defending existing wealth pools," with unlisted tech stocks, founder control, and intellectual property valuations becoming targets in the tax base competition.
Essentially, it is a capital concentration defense triggered by regulatory changes. The wealth tax is based on net asset value, while tech wealth is highly concentrated in founder equity, private company interests, and intellectual property; these assets have high valuations and high monetization costs, yet tax obligations can require cash payment. Therefore, capital will first invest in political organizations, legal designs, and identity migration to lower the probability of policy implementation, rather than waiting to passively sell assets after a tax bill appears.

- Ballots determine policy, funding determines ballot environment.
- The larger the paper wealth, the sharper the cash flow constraints.
