[California Bets on IPO Tax Windfall: SpaceX and AI Giants' Listings Could Bring Billions in Revenue] According to Deep Tide TechFlow, on June 18, CNBC reported that as potential IPOs for tech companies like SpaceX, OpenAI, and Anthropic approach, the state of California is expected to see a surge in IPO-related tax revenue. However, the actual scale and predictability of this increase remain highly uncertain. It is reported that SpaceX's IPO could become one of California's historic tax revenue sources. However, due to its unique employee equity incentive structure (RSU single-trigger vesting mechanism) and long-term prepayment tax arrangements, some of the tax revenue has already been realized prior to the IPO, weakening the traditional "concentrated tax explosion upon listing" model. California's Department of Finance and the Legislative Analyst's Office (LAO) pointed out that compared to Facebook's 2012 IPO, which brought approximately $1.3 billion in tax revenue, today's mega-IPOs theoretically have higher tax revenue potential. However, due to complex employee stock ownership structures, pre-IPO sales, and the increased use of tax avoidance tools, actual revenue may be more dispersed and harder to predict. Overall, while California is likely to benefit from a "super IPO cycle," the tax structure is shifting from a "one-time concentrated explosion" to "long-term dispersed realization," making fiscal growth more volatile and uncertain.
