El Paso, TX, September 29, 2026 —

San Francisco, CA – Sergey Brin, co-founder of Google, has made a substantial contribution of over $100 million to a campaign actively opposing California’s Proposition 40. This proposition, if passed, would introduce a one-time wealth tax specifically targeting billionaires within the state.

Proposition 40 proposes to implement a 5% tax on assets valued at more than $1 billion. The stated aim of the measure is to generate funding for various state programs. However, the initiative has encountered considerable opposition, primarily from ultra-wealthy individuals who have voiced concerns regarding the potential financial ramifications and the precedent such a tax could set.

The significant financial backing from Brin represents a major development in the ongoing debate surrounding wealth taxation in California. The opposition campaign, now bolstered by this substantial donation, is expected to intensify its efforts to inform voters about their concerns regarding Proposition 40.

Details regarding the specific financial impact on individuals or the projected revenue for state programs were not provided in the summary. The opposition’s arguments center on potential economic effects and the establishment of future tax policies. The proposal to tax assets exceeding $1 billion aims to address funding needs for state initiatives, but the debate highlights a broader discussion about wealth distribution and taxation among the nation’s wealthiest citizens.

The contractor or entity managing the campaign opposing Proposition 40 was not specified. The specific timeline for the proposition’s vote or further developments in the campaign were also not detailed in the provided information.
