Astera Labs Inc. (ALAB) surged 5.28% in pre-market trading on Tuesday, driven by positive developments from the Computex technology exhibition and broader optimism in the AI semiconductor sector.

At Computex, the company's management highlighted that its chip and optical solutions have been integrated into nearly 90% of global AI computing clusters, with its Scorpio X series entering volume production ramp. Additionally, the previously announced ten-year, $100 billion computing agreement between Anthropic and AWS continues to bolster supply chain sentiment, with Morgan Stanley noting that Astera Labs supplies switches and signal conditioning products for AWS Trainium 2 chips and is poised for Trainium 3 product ramp in the second half of the year.

The broader AI semiconductor recovery, exemplified by Broadcom's 6.46% surge on the same day, provided additional tailwinds for the stock, contributing to the pre-market momentum.
