Anthropic plans to invest more than $518 billion in AI infrastructure over the next 10 years, primarily through non-cancelable commitments with Google, Amazon, Microsoft and other partners, Reuters reported, citing a confidential filing. The strategy underscores the company’s effort to secure infrastructure for continued AI development and growth. The filing coincides with Anthropic’s release of Claude Sonnet 5.5 and comes as the company expands its model lineup ahead of a potential initial public offering (IPO). Market pricing suggests rising confidence that Anthropic’s valuation could reach $600 billion by the end of the year, reflecting the company’s reported financial backing. Market participants are watching its partnerships, potential funding and strategic announcements, including signals from Amazon and Google. Further IPO updates and product releases could affect market confidence and pricing, as well as the likelihood of reaching valuation targets by December 31.
