Share the canonical public link.
Anthropic expanded restrictions on secondary share purchases on May 18, 2026, jolting investor chatrooms and secondary markets that had priced shares above $900 billion. The company is in active talks to raise $30-50 billion at a valuation north of $900 billion, up from the $380 billion post-money valuation in its February 2026 Series G round led by GIC and Coatue. Secondary traders had marketed Anthropic shares at even higher implied valuations before the policy update. Anthropic eyes a 2026 IPO alongside OpenAI and SpaceX in a slate of trillion-dollar listings.
