- • Thiel has substantially escalated his political spending, having previously poured $102 million into Building a Better California, a group he co-founded with former Google CEO Eric Schmidt, demonstrating a sustained commitment to opposing wealth-tax proposals.

Summary
Peter Thiel, the venture capitalist and chairman of Palantir Technologies, has donated $3 million to the California Business Roundtable, a lobbying organization mobilizing opposition to California's proposed wealth tax initiative. The contribution signals significant financial backing for efforts to block what would become one of the nation's most aggressive wealth taxation measures targeting ultra-high-net-worth individuals.
The proposed California ballot measure, identified as Proposition 40, would impose a one-time 5% tax on any individual with a net worth exceeding $1 billion. The measure grants affected taxpayers a five-year period to pay the assessed tax, structuring the levy as a limited-duration rather than permanent wealth tax. For individuals with net worth between $1 billion and $1.1 billion, the tax rate would be reduced by 0.1% for each $2 million of net worth above the threshold, creating a graduated structure within the ultra-high-net-worth bracket.
Thiel's $3 million contribution to the California Business Roundtable represents a tactical investment in organized opposition infrastructure, though it sits below his broader political spending pattern. The venture capitalist has previously invested $102 million in Building a Better California, an advocacy organization he co-founded with former Google chief executive Eric Schmidt. This escalating financial commitment underscores Thiel's sustained focus on defeating wealth-tax legislation and shaping California's fiscal policy landscape.
The donation places Thiel among prominent billionaire voices actively funding ballot-measure opposition, positioning institutional opposition to the wealth-tax proposal as a coordinated effort rather than isolated resistance. The California Business Roundtable's focus on policies it views as anti-business suggests broader concerns among the wealthy-investor class beyond individual tax exposure, potentially framing the wealth tax as economically damaging to the state's business environment and investment climate.
