At [SpaceX's IPO](https://www.businessinsider.com/spacex-ipo-10-largest-public-offerings-ranked-by-proceeds-2026-6) valuation, that grant is estimated to be worth more than $4 million, assuming it was held.\n\nAt [Anthropic](https://www.businessinsider.com/anthropic-rewriting-startup-pay-levels-2025-9), engineers who joined in 2023 may now be sitting on equity worth tens of millions of dollars after the AI company's valuation surge.\n\n[OpenAI](https://www.businessinsider.com/openai-1-million-pay-packages-tech-memo-2025-8) shows a similar pattern, with some 2022 and 2023 equity grants to engineers now valued at over $50 million.\n\nThese are not guaranteed windfalls: variables such as vesting, dilution, and lockups mean employees may end up with less. And don't forget those [huge tax bills](https://www.businessinsider.com/tech-employees-sell-stock-avoid-capital-gains-tax-spacex-ipos-2026-6).\n\nStill, these estimates give a real taste of the wealth that Silicon Valley has created — and [spread among workers](https://www.businessinsider.com/silicon-valley-version-capitalism-works-equity-ipos-tax-2026-6).\n\n*Sign up for BI's Tech Memo newsletter *[here](https://www.businessinsider.com/subscription/newsletter/tech-memo)*.
