Anthropic confidentially filed its IPO prospectus in June 2026, with a Nasdaq listing expected as soon as August 2026 and a potential valuation of up to $2 trillion.[^1]

The filing comes as the company's Intelligence Threat Report discloses that a cell in northern Yemen attempted to use the Claude model to develop military guidance software for rocket systems.[^2]

The September report details that this group used Claude Code to create software for guided rockets, a long-range ballistic missile, and a hypersonic glide vehicle.[^3]

Specifically, a Houthi-controlled cell in northern Yemen utilized Claude Code to develop guidance, navigation, and control software for a guided rocket, a multistage ballistic missile, and an R2000 hypersonic glide vehicle variant.[^4]

Anthropic stated that the Yemeni cell used Claude to replace specialized engineering teams for software guidance, navigation, and weapon control, but no operational device has been deployed.[^6]

The company's September threat report also identified misuses by a China-based actor pursuing an anti-torpedo weapons system alongside the Yemeni work.[^7]

Anthropic published its AI-Native SDLC Playbook, asserting that code generation is no longer the bottleneck in software development.[^5]

A Yemen-based weapons engineering cell used Claude Code to develop guidance, navigation, and control software for rockets and missiles, though they failed to field an operational device.[^8]
