Anthropic IPO Delayed to November, Report Says
The listing slips to late October at the earliest and more likely November 2026, as Anthropic waits to show investors a stronger third quarter.
In short
Anthropic has reportedly pushed its planned October 2026 listing back to late October at the earliest and more likely November, so it can put a strong third quarter in front of investors first.
At a glance
- Listing reportedly slips to late October 2026 at the earliest, more likely November; October was the plan.
- Target valuation is about $2 trillion, with an offering of up to $100 billion.
- Q2 2026 revenue topped $11.5 billion, up from roughly $4.7 billion in the first quarter.
- Infrastructure spending rose from $3.4 billion to $5.6 billion, a 65% increase.
- The SpaceX capacity deal alone reportedly costs $1.25 billion per month.
Anthropic is holding off on its stock market debut. The listing, once aimed at October 2026, is now expected late October at the earliest and more likely in November. Advisors say the company wants to present strong third-quarter results before it goes public.
The size of the deal
Investors are working from a valuation of roughly $2 trillion, with the company looking to raise up to $100 billion. That would put it among the largest listings on record. OpenAI has already moved its own IPO to 2027, with Sam Altman pointing to safety concerns.
The case for waiting
Anthropic has a growth story worth timing well. Revenue climbed from about $4.7 billion in the first quarter of 2026 to more than $11.5 billion in the second, more than doubling. Adjusted operating margin moved from negative 13% to a positive single-digit figure over the same stretch.
Enterprise adoption tracks the same curve. The number of companies spending more than $100,000 a year went from 1,500 at the end of 2025 to 6,000 by the close of the second quarter. More than 1,000 now spend over $1 million, and more than 100 spend over $10 million.
The cost side keeps climbing
Infrastructure spending rose from $3.4 billion to $5.6 billion, a 65% jump. The capacity agreement with SpaceX accounts for $1.25 billion a month on its own, according to the report. Higher interest rates make the next build-out more expensive still.
Reporting also points to costs left out of earlier presentations, notably stock-based compensation, plus competitive pressure from OpenAI's Astra model and from cheaper open-weight rivals.
A risk nobody has priced
One item sits awkwardly in a prospectus: uninsured cybersecurity exposure traced to unintended hacks during safety testing, with Google and Meta reportedly caught up in similar incidents. How underwriters treat a liability of that shape is not yet clear.
What remains unconfirmed
Anthropic has not publicly committed to a date. The figures above come from Wall Street Journal and The Information reporting as summarized by the decoder. A second outlet we intended to check was not reachable during reporting, so its liquidity and cash-burn figures could not be verified and are deliberately left out of this piece.
