Analysis
Anthropic's IPO is shaping up as the swing vote for 2026's entire exit market. One long-time investor told Fortune's Term Sheet newsletter they expect the company to price around $1.8 trillion -- below Anthropic's own roughly $2 trillion target, though still enough to push post-IPO trading as high as $2.4 trillion. Fortune reported Oct. 21 that Renaissance Capital's Matt Kennedy expects a filing could come "as soon as" this Friday, with the Wall Street Journal and Bloomberg both pointing to a November listing.
The stakes go well beyond Anthropic itself. Pulse previously covered the leaked S-1 showing $16.3 billion in first-half 2026 revenue against an $80.7 billion net loss -- a gap this IPO has to convince public investors to underwrite.
The 2026 IPO market took in roughly $137 billion in proceeds in the first half, driven heavily by SpaceX's record $75 billion offering and $2.1 trillion first-day market cap. But the back half has been rougher:
“- Kepuni Holdings -- withdrew a planned $15 million Nasdaq listing.”
- Oura -- shelved its IPO hours before pricing.
- Kepuni Holdings -- withdrew a planned $15 million Nasdaq listing.
- Gravitics -- cut its IPO size by 60%.
- Elice Group (South Korea) -- fell 32% on its trading debut, the country's worst first-day drop for a raise over $100 million, per Dealogic.
University of Florida IPO researcher Jay Ritter argues the common thread isn't business quality -- it's price. Companies are pulling deals rather than accepting valuations below what they wanted, not because public markets have lost interest in growth stories outright. That's a more forgiving read for Anthropic than "the IPO window is shut": if Ritter is right, the problem is calibrating the ask, not whether a loss-making AI lab can go public at all.
Room for disagreement: a successful Anthropic listing near $1.8-2 trillion would be a genuinely different proof point than Lycia Therapeutics pricing a $264.6 million biotech IPO or a SPAC clearing a modest raise -- it would show public markets will underwrite mega-scale, loss-making AI infrastructure spend, not just binary, near-term catalysts. Kennedy's own view is that a clean Anthropic print would be a major win for the broader market, large enough to carry benefits into 2027 even if the actual listing slips past year-end. If Anthropic prices well, the lesson flips: discipline wasn't about rejecting AI-scale burn, it was about rejecting mispriced AI-scale burn.
Whichever way it breaks, bankers on other pending listings are reportedly watching Anthropic's reception before committing to their own early-2027 timing -- which makes this the rare single IPO that other companies' go-public plans are actually waiting on.
