Tom Lee says trillions in tech IPO supply won't crash the S&P 500

Tom Lee, chairman of Bitmine Immersion Technologies and co-founder of Fundstrat, does not expect the coming wave of mega IPOs to derail markets even if they could eclipse the entire dot-com boom in scale.

Lee recently discussed the potential effect of SpaceX, Anthropic, and OpenAI listing which could unleash trillions of dollars in new equity supply into public markets.

In inflation adjusted terms, Elon Musk's SpaceX alone could become the second largest IPO ever, seeking a market valuation above $1.5 trillion, behind only Saudi Aramco.

Lee acknowledged concerns about the amount of supply these listings could introduce into public markets, especially after the standard 90-day lock-up periods expire. He noted that SpaceX is likely the most anticipated IPO ever, Lee estimates the three IPOs could generate trillions in supply, equivalent to roughly 5% to 6% of the S&P 500’s total market capitalization.

Despite the scale, Lee does not believe the situation is necessarily outright bearish for the markets. He argues that family offices, pensions, and high net worth investors currently hold historically low allocations to public equities after years of favoring private markets and alternative investments.

There is significant capital available to absorb the liquidity as allocations rotate back toward U.S. public stocks, in Lee's view.

He also expects many early investors to hedge or borrow against holdings rather than immediately sell and trigger large tax events.

Lee also discussed cryptocurrency's underperformance against expectations despite growing institutional interest, highlighting how instant settlement and transaction verification are driving Wall Street’s push towards tokenisation, a point he previously made at Consensus Miami 2026.

Furthermore, Lee believes blockchain could provide a neutral framework for identity verification in an AI driven world. Banks are increasingly circling the industry because they recognize the significant revenue opportunities emerging from the convergence of crypto, AI, and finance, he added.
