What is driving the market?
Micron Technology’s shares hit a record high on Monday after the company announced a multi-year strategic agreement with artificial intelligence startup Anthropic, according to a company announcement. The deal excited investors ahead of Micron’s earnings report scheduled for Wednesday, according to the company’s announcement.
Anthropic has agreed to secure memory chip supplies from Micron Technology through a multi-year arrangement. Market analysts at Yahoo Finance said investors generally like long-term supply agreements because they reduce uncertainty about future sales.

The second reason for the positive reaction from investors is the partnership’s focus on product co-design. Anthropic not only buys memory products from Micron, but also works directly with the company to develop next-generation high-bandwidth memory (HBM) technology. Market analysts said investors viewed the tie-up as a sign that Micron Technology can solidify its position in the fast-growing artificial intelligence chip market.
The third reason investors cheered the deal was Micron’s investment in Anthropic itself. According to the company’s announcement, Micron participated in Anthropic’s Series H financing and became one of the investors supporting the artificial intelligence company.
As Yahoo Finance points out, some investors would see additional upside if Anthropic ends up IPOing at a very high valuation. This investment not only gives Micron Technology exposure to AI hardware demand, but also exposure to the growth of one of the leading AI model developers.
