Founders split on leaving California if billionaire wealth tax passes

Mark Cuban warned that a proposed California wealth tax could drive startup founders away, and three founders gave mixed reactions when asked if they would relocate.

In response to Rep. Ro Khanna, Mark Cuban warned that a statewide "billionaire tax" slated for a November vote would push founders who are rich on paper but cash-poor to exit California, calling those who stay "idiots." Cuban later clarified that not every founder would be affected and noted other states offer incentives. One outlet asked three founders about their plans: Jesse Tinsley, who runs Mainstreet.com, said he would relocate to Florida, citing the Laffer curve and public backlash concerns.

Jaspar Carmichael-Jack, co-founder of the AI firm Artisan, said he would seriously consider a move if the tax passed, noting the difficulty for illiquid founders. By contrast, Jensen Huang expressed acceptance of any taxes, and HiJenny founder Michal Cieplinski argued that the Bay Area remains essential for AI talent and that companies and employees would stay even if founders move.

Why it matters
