TechCrunch reports Anthropic's revenue grew 5x in roughly six months—from $9B at end-2025 to $47B annualized—as it filed a confidential IPO S-1; the still-restricted Mythos model, which found thousands of high-severity software bugs, is the company's most significant near-term revenue wildcard.

TechCrunch provides the most detailed financial picture of the Anthropic IPO cluster: revenue grew from $9 billion annualized at end-2025 to $47 billion as of May 2026—more than 5x in roughly six months. The $65 billion Series H was co-led by Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital, Capital Group, Coatue, and D1 Capital Partners, with broad institutional participation clearly timed ahead of the IPO.\n\nThe Mythos model is the article's most notable detail. Anthropic previewed Mythos in April 2026 but has kept access restricted after the model reportedly identified thousands of high-severity software bugs across codebases that needed to be fixed before wider release. The EU cybersecurity agency was reportedly set to receive restricted access as of Monday. Mythos's public availability is treated by TechCrunch as a potential major revenue catalyst in the post-IPO period.\n\nThe article contextualizes Anthropic's rise: founded in 2021 by former OpenAI employees, it was long considered an underdog that has now 'landed top-tier enterprise customers' with a focus on API services and enterprise tooling rather than consumer chatbot use. That enterprise focus distinguishes it from OpenAI's more consumer-heavy portfolio heading into public markets.
