Key Points
1
Anthropic’s $65 billion Series H funding round closed on May 28 and valued the company at approximately $965 billion; the financing was described as the largest single venture round in history.
2
OpenAI entered the public-markets queue shortly after Anthropic, confidentially filing its own draft S-1 with the SEC about a week after Anthropic’s June 1 submission.
3
Prediction-market traders have heavily favored an October listing: Polymarket gave Anthropic roughly a 91% chance of trading publicly by October 31, compared with about 7% by September 30.
4
The offering could coincide with other major AI-related listings, including a possible OpenAI IPO; the report also compared the potential deal with SpaceX’s June public offering at a $1.77 trillion valuation.
5
Kalshi trading swung sharply after Reuters reported the delay: contracts tied to an IPO announcement before October 1 fell from as high as 50 cents to as low as one cent, while October-oriented contracts gained attention.
Anthropic is pushing its long-awaited IPO to mid-October at the earliest, with the AI giant potentially going public just before November's U.S. midterm elections. CNBC reports the company will file its public prospectus in late September, following a confidential SEC submission in June. The listing could value Anthropic near $2 trillion — making it one of the largest public offerings ever and a major test of whether AI companies' sky-high private valuations will survive public-market scrutiny.
Anthropic raised $65 billion in May at a $965 billion valuation, the largest venture round ever. Now the company is finalizing a roughly $15 billion credit facility while Morgan Stanley, Goldman Sachs, JPMorgan, and Citi prepare the offering. Crypto.news notes the prospectus release slips to late September and the investor roadshow moves to mid-October, a delay that has already roiled prediction markets tied to the IPO timing.
OpenAI Follows Anthropic Into the IPO Queue
Anthropic's IPO push is not happening in isolation. OpenAI filed its own confidential draft registration statement with the SEC about a week after Anthropic's June 1 submission, signaling it is also gearing up for a public debut. The two companies are now racing to become the first major AI powerhouse to trade publicly — a landmark moment for the entire sector that will signal whether private markets and public investors see eye-to-eye on AI valuations.
Prediction Markets Swing Sharp on IPO Delay News
Traders betting on Anthropic's IPO timing got whipsawed by Reuters' reporting of the delay. Polymarket had given Anthropic a 91% chance of trading by October 31, but only 7% by September 30. When the October shift was announced, Kalshi contracts tied to an IPO announcement before October 1 crashed from as high as 50 cents to just one cent, while October-focused contracts surged. The wild swings show just how closely investors are watching the AI IPO calendar.
The timing is intentional. By launching the roadshow in mid-October, Anthropic can complete the listing in early November — right before the midterm elections. This window aligns with other potential AI-related public debuts, including possibly OpenAI. Some analysts have drawn comparisons to SpaceX's June public offering at a $1.77 trillion valuation, underscoring the historic scale of what Anthropic is attempting.
A $2 Trillion Valuation Test for AI Economics
The real question is whether Wall Street will pay $2 trillion for Anthropic. The company's $965 billion private valuation in May was already stunning — nearly three times what it was worth two years earlier. But public markets are ruthless. They care about revenue, path to profitability, and competitive moat. Anthropic still faces intense competition from OpenAI, Google, and others. A $2 trillion asking price would make this one of the largest IPOs in history and signal that public investors believe the AI boom is just getting started — or it could signal a reality check on private-market exuberance.
