Investors bullish on Anthropic despite risks
Tech investors are cautiously optimistic about Anthropic's S-1 filing for its upcoming IPO, which is expected to revive the AI trade and value the company between $1.5 trillion and $2 trillion. Despite concerns about AI commodification and its public benefit corporation structure, Anthropic reported an adjusted operating margin of 10% for the first half, with significant cash reserves of $112.4 billion plus $19.3 billion in securities. Analysts noted small net losses excluding stock-based compensation. Hyperscalers like Amazon and Alphabet, and chipmaker Broadcom, are seen as beneficiaries, with Broadcom leasing up to $63 billion in chips and networking products. Neocloud providers CoreWeave and Nebius Group may also benefit. Funds like The Growth Fund of America and T. Rowe Price ETFs hold direct stakes. The IPO is expected in mid-to-late November, though some caution about post-IPO performance and market strain, as exemplified by SpaceX's volatility.
Anthropic's IPO filing is significant for the AI industry, providing financial transparency and signaling market confidence despite valuation concerns. The public benefit corporation structure and the AI commodification risks could influence how AI companies are valued and governed.

Anthropic: What the S-1 Proves
This report examines Anthropic’s S-1, the first full look at the financials behind the most closely watched AI company heading to the public markets. It explains what Anthropic’s filing confirms about growth and profitability, and where the risks lie for anyone weighing the IPO.
Anthropic IPO Prospectus Reveals Losses, Growth, AI Risks
Anthropic's IPO prospectus reveals significant financials and risks. In 2025, revenue soared 12-fold to $4.6 billion, but operating losses exceeded $8 billion, with a net loss of about $42 billion (including a $34 billion accounting charge). Independent research firm New Constructs has labeled the IPO the 'most ridiculous IPO of 2026,' valuing the company at $150 billion against its $2 trillion target valuation, and questioning its viability due to rising competition from open-source models and the need to double Nvidia's profit to justify the valuation. Despite losses, revenue growth outpaces costs. The company plans $518 billion in compute commitments over 7-10 years, $410 billion non-cancellable. Two clients accounted for nearly a quarter of revenue. IPO targets November after an October delay. Meanwhile, OpenAI delays its IPO to raise $30 billion at a $1.4 trillion valuation, and AMD and Salesforce made notable acquisitions.
Anthropic IPO Tests AI Boom Valuations
Anthropic confidentially filed an S-1 with the U.S. Securities and Exchange Commission, initiating a highly scrutinized IPO that will be the first major public market test of frontier AI company valuations. The company had been valued at $965 billion and reported a $47 billion revenue run rate toward the end of May. Analysts told CNBC that the critical disclosure to watch will be Anthropic’s gross margin, which determines how sustainable high private-market valuations are given the high costs of providing AI services. The filing is expected to reprice private competitors and provide enterprises insight into the future cost of AI. The article also notes broader context in the IPO window, citing SpaceX’s $1.77 trillion valuation and Anthropic’s recent product expansion (Mythos access to 150 additional partners).
