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.
Anthropic vs OpenAI: Pre‑IPO BigAI Showdown
The article analyzes the pre‑IPO competition between Anthropic and OpenAI, highlighting major funding rounds, growth trajectories and product cadence. It reports Anthropic closed a $30 billion round while OpenAI is nearing a reported $100 billion round; Nvidia is reportedly in talks to invest up to $30 billion in OpenAI at a $730–$850 billion pre‑money valuation. Revenue projections and customer metrics from third parties (Epoch AI, Ramp) suggest Anthropic may outpace OpenAI in ARR by late 2026, supported by faster historical growth and recent model releases (Anthropic Sonnet 4.6, Google Gemini 3.1 Pro). The piece cites Ramp data showing high customer overlap (79% of Anthropic customers were already OpenAI customers), low churn (~4%), and growing dual adoption (16% of businesses pay for both). It also discusses agentic AI, Model Context Protocol (MCP), and profitability timelines (Anthropic possibly profitable by 2028; OpenAI possibly by 2031).
Anthropic Overtakes OpenAI as Hottest AI Upstart
Anthropic has accelerated ahead of OpenAI in the frontier AI model race, more than doubling its revenue from Q1 to Q2 while OpenAI’s revenue rose about 18% and its operating margins worsened, the Wall Street Journal reported. Reuters reported that Anthropic projects as much as $200 billion in 2028 revenue versus OpenAI’s $47 billion run rate disclosed in May. Analysts say the shift could reshape partner and supplier dynamics: companies tied to OpenAI (Oracle, CoreWeave, Broadcom, SoftBank) may face downside while cloud and chip providers tied to Anthropic (Google/Alphabet, Amazon) could benefit because Anthropic sources most compute from Google and Amazon. Market observers note interoperability via open-weight models and the potential for commoditization of frontier AI, but most do not expect OpenAI to disappear. The story is framed as market analysis with implications for stocks and industry supply chains.
