Anthropic IPO live updates: AI lab lost $80.7 billion in first half of 2026
All the details from Anthropic's IPO prospectus with the Securities and Exchange Commission.
Anthropic, the artificial intelligence lab, reported a staggering loss of $80.7 billion in the first half of 2026, according to its IPO live updates. The company had previously announced a $5 billion investment from Microsoft in November of the previous year, which valued Anthropic between $350 billion and $965 billion. Microsoft's stake in Anthropic reportedly gained $3.2 billion in May.
The AI lab signed a deal with Microsoft that required Anthropic to spend at least $44.9 billion with the tech giant between November 2026 and May 2023. This agreement could not be terminated unless Microsoft breached the terms or failed to deliver the necessary computing power. However, Anthropic acknowledged that its relationships with Microsoft, Amazon, Google, and Broadcom could create dependencies and potential vulnerabilities.
Microsoft integrated Anthropic's Claude large language models into its GitHub Copilot coding tool, Foundry model garden, and Copilot Cowork, a productivity task management product. The tech giant also offered competing AI services through its cloud platform, Microsoft Azure. The prospectus revealed that Anthropic pays fees to Microsoft, Amazon, and Google to establish a direct relationship with customers.
Additionally, the company relies on these three companies for computing power, which raises concerns about potential vulnerabilities.
