Chipmaker Micron Technology and AI company Anthropic have signed a deal to work together on the memory technology behind artificial intelligence, and investors liked what they saw.

According to Reuters and BNN Bloomberg, Micron said on Monday that the agreement covers the supply of memory and storage products, along with a strategic investment in Anthropic's latest funding round. BNN Bloomberg notes that Anthropic, the maker of the Claude chatbot, is considered IPO-bound.

The Decoder reports that Micron is investing in Anthropic's Series H round and securing a multi-year deal to supply memory for the infrastructure that powers Claude. The two companies also want to co-design AI memory architecture together. Anthropic co-founder Tom Brown describes memory as critical to both training and running Claude.

Markets reacted quickly. Crypto Briefing reports Micron shares rose 4% to a new all-time high, while BeInCrypto puts the jump at 5%, coming just ahead of the company's earnings. Analytics India Magazine framed the news as Micron both investing in Anthropic and partnering on AI memory infrastructure.

Not everyone is convinced. According to The Decoder, critics argue that "circular" deals like this one — where a supplier invests in a customer that then buys its products — are helping inflate an AI bubble.

Why it matters: memory chips are an often-overlooked bottleneck in AI, and this deal shows how chipmakers and AI labs are now tying their fortunes together — a strategy that is boosting share prices but also raising questions about how much of the AI boom is built on companies funding one another.
