SpaceX went public last week in what many called the largest initial offering ever. Its shares debuted at a valuation near $2 trillion. OpenAI and Anthropic filed confidentially for their own listings. Both AI leaders sit near $1 trillion marks. California officials saw dollar signs.
They still do. But the windfall looks different now. Less a sudden flood. More a slow trickle shaped by how tech pays its people.
Back in 2012 Facebook’s IPO handed California $1.3 billion in taxes. The social network carried a $104 billion valuation at the time. Simple math suggested much larger sums from today’s giants. Yet single-trigger restricted stock units change the picture.
These RSUs vest based on continued employment. Employees pay income tax each year as the shares vest. No massive bill hits all at once when the company lists. The state collects over time. The Next Web laid out how this structure spreads revenue and makes it harder to forecast.
Tender offers add another layer. SpaceX alone saw $6.6 billion in secondary sales at a $500 billion valuation. Employees and early investors cashed out before the IPO. They paid taxes then. The public listing generates less fresh taxable income.
But. The biggest leak may be loans against shares. Wealthy holders borrow instead of sell. They avoid capital gains. Interest payments replace tax bills. Elon Musk has used versions of this approach. The strategy known in some circles as buy borrow die lets fortunes grow while tax obligations shrink.
California’s Legislative Analyst’s Office calls the situation challenging. Revenue becomes less immediate. More unpredictable. Employee decisions drive the timing. So do market conditions. CNBC reported today that several factors complicate the equation for state budget planners.
Still the numbers tempt. Over 7,600 SpaceX workers live in California. Many in the Hawthorne area near Los Angeles. When they sell shares after the June 12 debut they face state taxes from 1 percent to 13.3 percent. That top rate kicks in for the highest earners. H.D. Palmer with the California Department of Finance told multiple outlets that exact collections remain impossible to predict.
Governor Gavin Newsom already adjusted his revised 2026 budget. He erased a potential deficit. Stronger income tax collections from tech and AI gains helped. Newsom’s team pointed to big share price increases across the sector. Forbes noted the effect should be positive even though SpaceX moved its headquarters to Texas.
The move stings in some ways. California lost the corporate headquarters. It forfeited future corporate tax base tied to the main office. Yet employee residency matters most for personal income taxes. Many longtime SpaceX staff stayed in the state. Former employees still hold shares too.
Ross Gerber runs Santa Monica-based Gerber Kawasaki. His clients include current and past SpaceX workers. He told Forbes the IPO would deliver a huge boost to California’s economy and tax coffers. Private conversations among investors echo that view.
Anthropic and OpenAI add to the mix. Both San Francisco companies filed recently. Anthropic moved first. Valuations hover near $1 trillion. Their employee counts run smaller than SpaceX. The tax impact per company may prove less dramatic. Combined they still matter.
State auditors stay aggressive. The Franchise Tax Board earns a reputation for tough enforcement. That helps capture what is owed. It cannot create revenue that modern pay structures push into future years.
Budget experts watch volatility. California depends heavily on personal income taxes from high earners. Stock-based compensation amplifies swings. A market dip could reverse gains fast. The Legislative Analyst’s Office warned in recent outlooks about structural deficits ahead despite current strength.
So officials temper expectations. They avoid locking in specific IPO revenue figures. Palmer said the Department of Finance sees upside but offers no precise forecast. Timing of sales matters too much.
History offers lessons. The dot-com boom brought massive surpluses followed by painful drops. Lawmakers remember those cycles. This time artificial intelligence powers the surge. Demand for chips data centers and talent looks sticky. Yet nothing guarantees endless growth.
Employees face their own choices. Some sell immediately to diversify. Others hold for years. Founders and early investors often face lockup periods. Their decisions shape when California sees the money.
The state’s top rate on capital gains matches ordinary income. That 13.3 percent figure exceeds most other states. It gives California an edge over Texas which has no personal income tax. SpaceX’s relocation highlighted the contrast. The IPO payday still flows largely to Sacramento.
Recent trading activity hints at broad interest. Charles Schwab reported one of its busiest days ever after the SpaceX debut. Retail and institutional buyers piled in. That liquidity could encourage more selling over time which feeds tax collections.
Yet complexity reigns. Private tender offers drained liquidity before the IPO. Many shares changed hands quietly. Taxes on those transactions already hit state books in prior quarters. The public event matters less than it once did.
Analysts at the LAO stress employee and investor behavior as the key variable. No model predicts perfectly how many people cash out in year one versus year five. Market performance adds another wildcard. Strong post-IPO performance encourages holding. Weakness forces sales.
California built its budget assuming continued tech strength. Newsom’s May revision removed the deficit projection for the next two years. AI enthusiasm and stock market records drove the improvement. The three pending or completed IPOs represent the next test.
Even without exact numbers the direction looks clear. Billions will flow. The question centers on concentration and timing. A one-quarter windfall that balances the books looks unlikely. A multi-year boost that supports ongoing programs appears more realistic.
Franchise Tax Board audits will catch aggressive avoidance. Loans against shares still generate interest deductions but face scrutiny. The state knows the tricks. It counters where it can.
Tech compensation evolved. What worked for Facebook no longer applies cleanly. Single-trigger RSUs became standard to manage tax burdens for employees. Companies adopted them to stay competitive in talent wars. The side effect hits state revenue timing.
Investors adapted too. Secondary markets matured. Tender offers let early backers exit without waiting for IPOs. That reduces the taxable event at listing. Everyone adjusts.
California adapts in its way. It counts on the sheer size of these deals. Even a diffused tax take from trillion-dollar companies dwarfs past events. The state just cannot bank on it arriving in one neat package.
SpaceX’s debut already delivered for workers and the state. OpenAI and Anthropic will follow. Their listings mark a new era for public markets and for California’s finances. The money comes. Just not exactly as first imagined.
