Sergey Brin has given $102 million to defeat California's Prop 40, a one-time 5% billionaire tax that could cost him about $13 billion. The state's $100 billion estimate depends as much on how many of its 200 billionaires stay resident as on the November vote.
Reality
PPIC's September survey puts Prop 40 at 52%, Prop 41 at 51% and Prop 42 at 54%, and Prop 40 takes effect only if it outpolls both in yes votes. Every gap between the three sits inside a 3.8-point margin of error.
Reality
The San Francisco Democratic Party broke with its state party 17-4 to oppose Prop 40, but the six billionaires who have already ended their California residency are the only votes on this measure that are already counted.
Reality
Proposition 40 would take 5% once from anyone worth over $1 billion. August polling puts it at 48% among likely voters and 75% among 18-to-29s. The composition of the November electorate is the only number that decides it.
Reality
The CPA body opposes Proposition 40 on administrability grounds, then endorses Proposition 42, which would bar the tax outright. Approval votes, not a majority, settle it.
Reality
A 5% levy on about 200 people was costed against wealth that has already moved. Fortune counts roughly $29 billion gone, and the two men at the top were 28.5% of the base.
Reality
John Doerr put in $7.5 million and Chris Larsen $10 million against a one-time 5% wealth tax. Measured against what the measure would cost them, that is cheap insurance.
Reality
Mark Cuban and Ro Khanna spent a weekend arguing on X about California's Proposition 40. The operative question for founders is where the cash comes from.
Reality
California's billionaire tax faces a nine-figure defense built as ballot engineering: two counter-measures that only have to outpoll Prop 40, not beat it head-on.
