A viral chart shows SpaceX, Anthropic and OpenAI now carry a combined $5.2T valuation, exceeding the $4.1T IPO-day value of 3,365 US tech companies since 1980 — AI is pulling trillion-dollar price discovery into private markets before IPO.

The author argues this isn't dot-com territory: median US tech IPOs traded at 43x (1999) and 49.5x (2000) sales after day one, while OpenAI sits near 30x ($1.2T vs $40B annualized revenue) and Anthropic around 31x ($2T vs $65B+ run rate).
