On May 28, Astera Labs rose 4.63% in regular trading, trading at $336.925/share, with trading volume of approximately $182 million. The stock rebounded sharply after multiple sessions of pressure from a recent analyst downgrade.

On the news front, Anthropic signed a ten-year, $100 billion compute agreement with AWS to procure Trainium chips, Graviton processors, and 5-gigawatt computing capacity. JPMorgan analysts noted that Astera Labs is a key Amazon supplier, providing switches and signal conditioning products for Trainium 2, with Trainium 3-related products set to ramp in the second half of the year. The firm may also participate in Trainium 4 development, making it a direct beneficiary of this landmark deal.

Additionally, the company announced it will host press conferences, live demos, and technical sessions at Computex, showcasing advances in AI infrastructure connectivity. Management stated its chips and optical solutions are integrated into nearly 90% of global AI compute clusters, with the Scorpio X series entering production ramp. Despite Northland Capital previously downgrading the stock to Market Perform on valuation concerns and fears of hyperscaler AI capex cuts in 2027, the massive AWS-Anthropic commitment helped offset those headwinds.
