Nebius jumped 33.92% on reports of acquiring AI21 Labs, while CoreWeave gained 25.63% following deals with Anthropic, Meta, and Google.

Google's TurboQuant algorithm reduces AI memory requirements by 83%, negatively impacting memory chipmakers like Micron and SanDisk. However, three stocks could benefit: Qualcomm (mobile AI processors), Broadcom (data center networking), and TTM Technologies (circuit boards), as lower AI costs may increase overall demand and deployment across industries.

The author highlights three lesser-known AI stocks worth watching: CoreWeave (AI infrastructure/data centers), TTM Technologies (circuit boards for data centers), and Fastly (content delivery and cybersecurity). All three show strong revenue growth, but only TTM is currently profitable. CoreWeave faces high debt and operational costs despite impressive sales growth, while Fastly is reducing losses. The author is monitoring these stocks for potential price dips before investing.
