# Thiel California Wealth Tax Donation On January 14, 2026, Fortune reported that [[Peter Thiel]] had made what it called his "biggest donation in years" to help defeat a proposed California billionaire wealth tax: **$3 million** to the California Business Roundtable's opposition effort, in a contribution dated **December 29, 2025** (Fortune; Finviz). That clears the §7.1 $1M individual-donation threshold. The measure qualified in June 2026 as Proposition 40 on the November 3, 2026 ballot; see [[California Billionaires Tax]]. ## Significance Single largest personal political move by [[Peter Thiel]] in years and directly tied to the California Tech Exodus narrative documented elsewhere in the KB. The donation is a defensive move — California-based and California-adjacent tech billionaires (Thiel, [[Marc Andreessen]], [[David Sacks]], [[Larry Ellison]], etc.) face direct personal tax exposure under a wealth tax, making this a coordinated billionaire-class defense against state-level wealth taxation. Likely paired with other tech-billionaire contributions to the opposition campaign. ## See Also - [[Peter Thiel]] - [[Marc Andreessen]] - [[California Billionaires Tax]]
