Overview
- This week Mark Cuban warned he would make leaving California a condition of some investments and said the 5% one-time tax misunderstands founders who are wealthy on paper but lack cash to pay it.
- Representative Ro Khanna defended Proposition 40 and proposed a state loan program secured by founders’ shares so illiquid owners could borrow to meet the tax and repay over time.
- Nonpartisan analysts and the Legislative Analyst’s Office say revenue estimates are uncertain, noting supporters’ $100 billion figure is likely far too high and out-migration could cut future income-tax receipts.
- Startup founders are divided about leaving California, with some planning moves to states like Florida or Texas and others citing the Valley’s talent and networks as reasons to stay.
- The public clash has sharpened fundraising and political mobilization ahead of the November vote, but unresolved valuation, enforcement and legal questions leave the measure’s real impact unclear.
