Nasdaq and NYSE debuts, S-1 filings and the American IPO pipeline.
A record SpaceX listing, a blockbuster Cerebras debut, and confidential filings from OpenAI and Anthropic have turned 2026 into the busiest US technology IPO year in half a decade.
SpaceX is said to be pursuing the biggest stock debut in history, built on a cash-generative Starlink unit attached to costly space ambitions. The reported scale, and the risks, are unusual.
Anthropic has confidentially filed for an IPO and OpenAI has cleared the structural path to one. The frontier model labs now face the gap between private valuations near $1 trillion and the cash burn of training their models.
The wafer-scale chipmaker priced far above its range and nearly doubled on debut. The harder question is whether a non-Nvidia AI silicon company, long dependent on a single Abu Dhabi backer, can keep public investors.
