Anthropic has declined venture capital offers valuing the AI startup at $800 billion or more, despite intense interest from investors eager to match or surpass its rival OpenAI's record-breaking $110 billion funding round. The Claude maker's decision comes as OpenAI recently secured an $852 billion post-money valuation, dwarfing Anthropic's previous $380 billion valuation after a $30 billion round. Analysts note Anthropic's reluctance may stem from its massive capital demands, including $50 billion allocated to building data centers and billions more spent on Microsoft and AWS cloud infrastructure.

While the company reports $30 billion in revenue by March 2026 — up from $9 billion in 2025 — investors argue its growth justifies higher valuations. Secondary markets show surging demand for Anthropic shares, with traders betting on a potential valuation leap if the startup accepts future funding. No official comment was issued by Anthropic, leaving the door open for a shift in strategy.

This standoff highlights tensions in the AI sector, where capital competition mirrors technological races.
