Anthropic’s planned initial public offering (IPO) will be a major test for an increasingly jittery Wall Street, but investors say the company has limited alternatives: simple arithmetic and scale mean Anthropic has outgrown private fundraising as its primary financing option.
Why it matters
Leading AI companies such as Anthropic and OpenAI are accumulating 12‑figure commitments for computing and infrastructure that strain the financial system. With private borrowing costs rising, investors see the deep liquidity of public markets as the most viable way to fund the next phase of capital‑intensive AI buildout.
State of play
A draft IPO prospectus seen by The Wall Street Journal indicates Anthropic’s computing commitments could reach $750 billion in the coming years. According to that draft, the company already faces more than $600 billion in future infrastructure costs and is negotiating additional deals that could add roughly $150 billion.
Financials present a mixed picture: Anthropic reported $16.3 billion of revenue in the first half of 2026, up from $1.1 billion a year earlier, but it also disclosed an $80.7 billion net loss for the same period. The bulk of that loss is tied to accounting charges related to fundraising, per the WSJ.
Why public markets
Investors tell Axios that these numbers create a funding gap only the public markets can bridge. OpenAI’s most recent capital raise — the largest in history — secured more than $120 billion but took months to arrange, underscoring how difficult it is to replicate that feat in the current market.
Demand for Anthropic shares is reportedly very high — an often‑cited anecdote notes an individual who offered nearly $5 million in personal real estate to get allocation — but deteriorating market sentiment raises the stakes for any IPO. If successful, a public listing could help assuage investor doubts about whether the AI expansion is investible at scale.
Follow the money
Private sources of capital are becoming harder and more expensive to access. The Financial Times reports Anthropic is offering Blackstone a yield exceeding 10% on $9 billion of junior debt as part of a record $60 billion chip‑financing package. That rate is higher than an earlier financing that carried an 8.5% coupon, suggesting private investors are demanding greater compensation for AI‑related risk.
Timing and delays
Anthropic had been widely expected to go public in September, but the timeline slipped after the departure of a researcher and a series of safety incidents that renewed public focus on AI‑safety issues. The company is now expected to IPO before Thanksgiving.
Broader market context
The IPO comes amid anxiety about the AI trade on Wall Street, particularly for companies that rent computing capacity or build data centers. Examples of recent market skepticism include:
- Nvidia‑backed Australian data center company Firmus canceling its planned IPO amid volatility.
- South Korean AI cloud provider Elice seeing its shares plunge 32% on debut despite rapid revenue growth.
- Rising concerns about AI infrastructure debt pushing borrowing costs higher for companies like CoreWeave, with yields on some bonds approaching 15%.
Reality check and conclusion
Anthropic is not a typical startup. One investor told Axios the company is ready for public markets given its scale and maturity and described its latest financial results as “spectacular,” countering worries about slowing revenue growth.
Although Anthropic may have to list under less‑than‑ideal conditions, investors view an IPO as the most pragmatic path to access the deeper pools of capital needed to sustain the AI boom and to subject that expansion to the market’s ultimate test.
