Anthropic vs. OpenAI: IPO, Profitability & Enterprise Edge

Anthropic is gaining an edge over OpenAI, especially with enterprise customers. The company's rapid growth is speeding up its timeline for profitability. Both companies, behind ChatGPT and Claude, are valued at nearly one trillion dollars. They have filed confidential registration statements with the U.S. Securities and Exchange Commission, hinting at potential IPOs. ChatGPT initially dominated the AI market with one billion monthly active users. However, Anthropic focused on the enterprise segment, with approximately 80% of its revenue now coming from businesses using its API and developer tools. This focus has boosted Anthropic's annualized revenue run rate to $47 billion as of mid-2026, a significant jump from $9 billion at the end of last year. OpenAI, in contrast, generates only about 40% of its sales from enterprises. While both companies have been unprofitable due to investments in research and development, Anthropic reportedly achieved its first operating profit in the second quarter. OpenAI, on the other hand, had a net loss of about $38.5 billion last year and doesn't expect to be profitable until at least 2030. This rapid shift in profitability and market focus could impact future investment opportunities in the AI sector.
