California expected a tax bonanza from AI IPOs. Modern compensation structures may blunt the windfall.

What happened

California expects a major tax windfall from the impending IPOs of AI giants OpenAI and Anthropic, alongside SpaceX, which is valued at $2.5 trillion. All three companies have significant operations or headquarters in the state. Valuations for OpenAI and Anthropic are reportedly approaching $1 trillion each ahead of their planned public listings later this year. However, modern compensation structures like stock options and deferred equity could reduce the state’s tax take from these IPO events. Similar patterns were observed after Facebook’s 2012 IPO.

Why it matters

The potential tax revenue from these IPOs represents one of the biggest opportunities California has seen, coming from its position as a hub for AI innovation and high-value startups. Yet, it is not guaranteed because companies increasingly compensate key employees through equity that may not fully vest or be taxed during the IPO. This means California’s expected windfall could be smaller than headline valuations suggest, putting pressure on state budgets relying on capital gains and income taxes from tech exits. For investors, founders, and employees, this dynamic affects how wealth is realized and taxed post-IPO, changing incentives around compensation and timing.

What to watch next

Track the specific IPO structures OpenAI and Anthropic use, especially how they handle employee equity plans. This will determine how much capital gains tax revenue California can collect. Also watch for legislative or regulatory changes in California that might respond to these shifting compensation trends. Finally, monitor broader adoption of these modern pay schemes across tech firms, as they could reshape how states capture value from tech booms going forward.
