Anthropic's $30 Trillion Valuation Criticized

Investors Eye $2 Trillion IPO Valuation for Anthropic
Anthropic is reportedly preparing an autumn IPO after filing a confidential SEC application in early June and entering a quiet period, with investors and banks modeling valuations as high as $2 trillion. Reuters and other outlets say those valuations lean on aggressive multi-year revenue forecasts: the company reported a revenue run-rate of roughly $47 billion in May 2026 (up from about $9 billion at end-2025) and projects roughly $190–200 billion for 2028; Q2 2026 guidance included at least $10.9 billion in revenue and $559 million operating profit. Banks are using comparables such as Palantir, Cloudflare and SpaceX and high revenue multiples to price the deal. Anthropic faces regulatory and operational risks—U.S. export controls briefly halted distribution of Fable 5 and Mythos 5—and other challenges including a Pentagon legal dispute, competition from lower-cost Chinese models, infrastructure costs, and reported talks to acquire Decart for about $6 billion.
Anthropic Declines VC Offers Valuing It at $800B+
Anthropic has reportedly rebuffed venture capital offers that would value the company at $800 billion or more, according to Bloomberg and TechCrunch. The startup, maker of the Claude family of models, previously raised a $30 billion round at a $380 billion valuation and faces large capital needs — including reported commitments of $50 billion for data centers, $30 billion for Microsoft cloud services, and ongoing multi‑billion dollar AWS spend. Investors are reportedly encouraged by Anthropic’s rising revenue (cited as $30 billion by end of March, up from $9 billion at end of 2025) and strong secondary‑market demand for its shares. Anthropic declined to comment. The situation could change if Anthropic opts to raise capital on favorable terms that would potentially exceed its prior valuation or rival OpenAI’s $852 billion post‑money valuation from February.
Anthropic’s Rise Spurs Investor Doubts About OpenAI
TechCrunch reports that some investors are questioning OpenAI’s $852 billion private valuation as Anthropic’s rapid growth reshapes investor sentiment. According to the Financial Times, Anthropic’s annualized revenue rose from $9 billion at the end of 2025 to $30 billion by the end of March 2026, and the company carries a roughly $380 billion valuation. Secondary-market demand for Anthropic shares has reportedly outpaced demand for OpenAI, and one investor said justifying OpenAI’s latest round would require assuming an IPO valuation of $1.2 trillion or more. Iconiq Capital partner Roy Luo, who has invested heavily in Anthropic, contrasted positions; OpenAI CFO Sarah Friar pointed to the company’s $122 billion raise as proof of ongoing investor confidence.
