All eyes are on Anthropic now with their IPO heavily expected to hit the market in October.
Anthropic appears to be moving closer to its initial public offering (IPO), which undoubtedly is one of the most closely watched technology listings of 2026.
The emerging consensus is that Claude’s maker could reach the public markets this fall; however, there are still a few important caveats and clarifications.
Prediction Markets Lean Toward October
While in no way a certainty, prediction market traders are leaning heavily in the direction that the IPO will come in October.
As you can see on the Polymarket snapshot, the contract tracking whether Anthropic will go public by September 15 implies just a 2% chance, while the probability for September 30 stands at 10%. By October 31, however, the odds jumped to 70%, and the market shows an 83% chance of an IPO by the end of this year.
Notably, the October probability had increased sharply in recent trading sessions, suggesting that users are becoming more confident that the listing could happen during that month.
Reports Also Point to Fall Listing
Not surprisingly, that view is also largely supported by recent reporting. A report from the Wall Street Journal said that the firm’s executives have been meeting with prospective investors to strengthen confidence ahead of an IPO that could arrive in September or early October.
Anthropic has also taken a major procedural step: the firm confidentially filed for a US IPO in June, giving it flexibility to move once regulatory review and market conditions allow it.

But that’s not the only impressive part about the IPO. Another report outlined that some investors are targeting a valuation of $2 trillion or even more for an October debut. This would be more than double the $965 million post-money valuation that Anthropic received in its May funding round, although the company has not publicly confirmed either the IPO date or the valuation.
$2 Trillion Valuation?
Whether participants in the IPO and public investors will support such a massive figure is likely to depend on the confidence placed in Anthropic’s growth projections.
Reuters reported that the company is forecasting roughly $190 billion to $200 billion in revenue in 2028, compared with a $47 billion annualized revenue run rate disclosed in May. Bankers and investors are now looking unusually far into the future when they assess what the firm could be worth. They are attempting to account for the company’s rapid growth and the high costs of training and operating cutting-edge AI models.
