Anthropic and OpenAI have launched a race for the public markets with confidential IPO filings.
Anthropic, the developer of Claude AI, submitted its filing on June 1, 2026. OpenAI, the creator of ChatGPT, followed with its own submission on June 8, 2026.
Both companies are targeting stock market listings in the second half of 2026. The firms are seeking valuations approaching $1 trillion.
The filings will test investor appetite for the capital-intensive AI sector. Both companies report massive revenue growth. Anthropic reportedly nears profitability faster than the currently loss-making OpenAI.
