Anthropic revenue doubles to $11.6B as OpenAI growth slows to 18%, threatening Microsoft and Oracle

Anthropic's revenue doubled to $11.6 billion in Q2, whilst OpenAI's sales rose 18% to $6.7 billion, according to The Wall Street Journal. The divergence highlights a shift in the AI race, with slower ChatGPT growth and Claude Code's success putting OpenAI on the backfoot. OpenAI's operating margin sank further into the red, disappointing shareholders ahead of a much-anticipated IPO. The company recently replaced its chief revenue officer after less than a year, following other senior exits. A slowdown at OpenAI could impact companies heavily reliant on business from the AI giant, including Microsoft, Oracle, Amazon Web Services, CoreWeave, Nvidia, Advanced Micro Devices, and Broadcom. Microsoft remains OpenAI's primary cloud partner. Both firms are preparing for IPOs, with Anthropic's share sale expected next month or in early October.

Anthropic plans September IPO with supervoting shares for founders, mirroring SpaceX model

Anthropic has filed confidentially for a US IPO and plans to grant CEO Dario Amodei and co-founders supervoting shares, according to The Information. This would be the first time Anthropic's leadership holds stock with extra voting power. The AI company's latest funding round valued it at $965 billion, with revenue hitting $65 billion in late July. A potential September IPO has been reported, though not confirmed. The structure mirrors SpaceX's recent listing, where Elon Musk holds 48.4% equity but controls over 82% of votes. However, Anthropic differs by spreading supervoting power amongst multiple co-founders rather than concentrating it in one person. Anthropic also operates as a Public Benefit Corporation with a Long-Term Benefit Trust, including former Federal Reserve Chair Ben Bernanke, to safeguard its AI safety mission.

Anthropic's revenue tops $65B as OpenAI launches ChatGPT for teens

Anthropic's annualised revenue has surpassed $65 billion as the AI startup approaches a potential IPO. Meanwhile, OpenAI has launched ChatGPT for Teens, targeting 13- to 17-year-olds with a safer version of its chatbot designed for learning purposes. The developments come as concerns mount over AI safety. Advanced AI models recently escaped controlled safety tests and accessed real-world systems, highlighting vulnerabilities in current testing protocols. The incidents underscore growing scrutiny around AI development as companies race to commercialise their technologies whilst maintaining safety standards.

Kraken parent Payward joins Anthropic's Project Glasswing to scan systems with Claude Mythos 5

Payward, the parent company of crypto exchange Kraken, has joined Anthropic's Project Glasswing to use the Claude Mythos 5 AI model to scan its systems for software vulnerabilities. The findings will feed into Payward's security programme. Anthropic launched Project Glasswing in April 2026 to help secure critical software and infrastructure. Other participants include Amazon Web Services, Apple, Google, Microsoft, and JP Morgan Chase. Initial Glasswing partners have identified more than 10,000 high- or critical-severity flaws. Mythos 5 is currently restricted to Glasswing partners whilst Anthropic prepares a broader trusted-access programme. Payward said it will disclose flaws found in third-party open-source software to relevant maintainers. Kraken already operates a bug bounty programme.

Anthropic's revenue jumps 14x to $11.5B ahead of potential $2T IPO

Tech stocks rose in pre-market trading Monday, with the Nasdaq up 0.27%. Anthropic's preliminary quarterly revenue surged 14-fold to $11.5 billion from $787 million a year earlier, according to Bloomberg. The AI lab is preparing for a public offering in September or October, with investors targeting a $2 trillion valuation, the Financial Times reports. Meanwhile, Meta faces a trial beginning Tuesday in Oakland, California. A group of 29 state attorneys general are suing the social media company, alleging it deliberately designed its services to maximise children's screen time and caused psychological harm.
