Marvell (MRVL) Surges as Amazon (AMZN) Plans External Sales of Trainium AI Chips

Marvell Technology (MRVL) shares surged 7.27% to close at $310.58 on Thursday, June 18, 2026, following reports Amazon (AMZN) plans to sell its custom Trainium AI chips to external companies for their data centers. This strategic shift signals a significant market expansion, directly benefiting Marvell as a core infrastructure partner for Amazon's Trainium platform. As a key design and manufacturing partner for Amazon Web Services (AWS) Trainium AI chips, Marvell stands to gain from the platform's external expansion. Marvell's trading volume on Thursday reached approximately 188 million shares, over five times its three-month daily average of 36 million shares. Amazon's stock also rose 2.89% to $244.37. This marks a strategic pivot for AWS, which traditionally kept its self-developed chips for internal cloud services. Amazon CEO Andy Jassy previously stated the chip business could generate around $50 billion in annualized revenue if operated as a standalone entity selling to AWS and third parties. This plan signals robust, expanding AI infrastructure demand.
