California expects a major tax boost from upcoming initial public offerings, particularly SpaceX, OpenAI, and Anthropic. These deals could generate substantial capital gains tax revenue when founders and early investors cash out their shares.
The state faces a complication, though. California's top capital gains tax rate sits at 13.3 percent, the highest in the nation. This aggressive rate may push wealthy IPO beneficiaries to relocate before selling shares, shifting their tax liability to other states.
SpaceX remains privately held but faces pressure to go public. OpenAI and Anthropic, both valued in the tens of billions, could launch IPOs within the next few years. Employees holding stock options and early venture investors stand to gain hundreds of millions or more when these companies list.
California's budget relies heavily on capital gains taxes from wealthy residents. In strong market years, this revenue can swing wildly. A single mega-IPO from a company like SpaceX could inject billions into state coffers. But the timing matters. If founders and major shareholders leave California before IPO lockup periods expire, the state loses that tax revenue entirely.
Experts note several other factors limiting the windfall. Not all shareholders live in California. Some proceeds flow to institutional investors and pension funds based elsewhere. Additionally, federal tax obligations take priority. After paying Uncle Sam, IPO beneficiaries may have less incentive to rush into California's 13.3 percent bite.
The state already struggles with tax competitiveness. Texas, Nevada, and Florida impose no state income tax. Even within high-tax states, New York's top rate is 10.9 percent. California's rate encourages relocation planning among the wealthy.
Governor Gavin Newsom has resisted lowering capital gains tax rates despite the flight risk. The state budgeted for continued strong IPO activity but hasn't factored
