Anthropic IPO Filing Sparks Fierce Bull-Bear Debate
Anthropic filed its IPO prospectus on October 26, immediately drawing intense analysis from prominent commentators and investors: valuation, compute debt, and governance structure became the flashpoints, with bears and bulls clashing sharply.
Confirmed
- NYU valuation professor Aswath Damodaran published a long piece, "The Anthropic Prospectus Arrives," valuing Anthropic's equity at roughly $1.475 trillion and saying he would decide whether to buy or sell accordingly. He noted revenue grew about 14x year-over-year in the first half, but Q3 growth slowed, OpenAI is taking share, and the company is cash-constrained; he also blasted the governance structure—7 co-founders hold 50.1% of voting power through a single share, a design he said "would make Kim Jong-un blush" (m2/m3/m7/m8/m9).
- Tech commentator Ed Zitron published "Exit Liquidity," attacking the S-1 as "deliberate deception": commitments totaling over $800 billion are largely undelivered, results are dressed up with an "unusual quarter," worsening Q3 data was not disclosed, and investors are being used as exit liquidity (m1/m4).
- Michael Burry, citing the filing, warned the entire AI boom is "catastrophically fragile," pointing to roughly $537 billion in compute payment obligations that pending deals could push to $800 billion (m5).
- sweatystartup posted a long thread analyzing the IPO deal structure, which ramagetime endorsed: Google and Amazon together injected about $26 billion in cash into Anthropic, money that flows almost straight back via compute and chip purchases—ramagetime called it "the heist of the century" (m10).
- Investor Nic Carter commented on Zitron's stance: on the surface the S-1 data refutes Zitron's bubble thesis, but he expects Zitron won't stop posting—his content is essentially "a placebo for those who missed out," a narrative needed by people who skipped the biggest investment theme of the past century (m6).
Why it matters
- This is a rare, high-quality bull-bear showdown centered on the same prospectus: a distinguished valuation scholar puts a trillion-dollar price on the company while famous shorts (Zitron, Burry) point straight at compute liabilities and disclosure flaws—their disagreements mark exactly the watershed for how the market prices AI assets.
- If the $537 billion compute obligations and $26 billion in tech-giant "circular funding" hold up, Anthropic's growth narrative is deeply tied to a handful of cloud vendors, and its sustainability depends on whether those contracts convert into revenue.
