Anthropic has confidentially filed its IPO prospectus with the SEC, as reported by CNBC on June 3, 2026 (source 9). The filing positions Anthropic among a wave of high-profile AI IPOs, including SpaceX and OpenAI. This move follows Anthropic's $65 billion funding round at a nearly $1 trillion valuation earlier in 2026 (source 17). Separately, Broadcom disclosed that Anthropic placed a $10 billion custom AI chip order (source 8), and Broadcom is expanding its AI compute initiative for Anthropic (source 1). These developments underscore massive demand for Anthropic's models. Additionally, Project Glasswing, which gives early access to Mythos, has been expanded to 150 organizations (source 5 and source 12). The IPO filing is a strong signal of market confidence and capital access, despite regulatory headwinds such as the DoD supply chain risk designation (source 2). Overall, Anthropic's aggressive scaling and IPO readiness point to upward momentum.
