Anthropic (maker of Claude) filed confidentially in June and, per The Information and Motley Fool, will publish its prospectus right after Labor Day for a late-September or early-October NASDAQ listing. Reported valuation targets range from ~$965B to $2T; either would eclipse SpaceX's June record. Morgan Stanley, Goldman Sachs and JPMorgan run the book. The deal may let existing holders sell into the IPO and carry a lock-up longer than the usual 180 days.

OpenAI filed confidentially in May at a valuation band of ~$852B to $1T+. In August, CFO Sarah Friar told employees the company 'will be a public company in 2027' or sooner and that it is 'running our own race' against Anthropic's fall debut. Polymarket odds of a 2026 listing collapsed on the comment. Still to finish: the ~$830B pre-IPO round and the conversion to a for-profit public benefit corporation.

The world's #2 memory maker (and ~60% of the HBM market) completed a ~$26.5B NASDAQ ADR listing, ahead of Alibaba's $21.8B in 2014. Shares rose 13% on day one and peaked near $195 in August. Proceeds fund the Yongin fab and advanced packaging. A direct NAS100-eligible rival for MU — the live price sits in the card above.

ChangXin Memory Technologies, China's only mass-production DRAM maker (#1 in China, #4 globally by capacity), soared ~466% on its STAR Market debut after raising ¥57.9B — Asia's biggest IPO of 2026 and enough to make it the most valuable company listed on mainland China. Not a NAS100 name, but the biggest supply-side threat to MU and SK hynix pricing. YMTC and UniIC are next in the pipeline.

SpaceX nearly tripled the largest-ever IPO capital raise, then gave back a large slice of the pop (see the live SPCX card in the Tech & AI section for today's distance from the high). The staggered insider lock-up schedule is the next supply event to watch, along with index-inclusion flows and its first earnings as a public company.
