Qualcomm acquires Modular for $3.9 billion, bolstering its AI infrastructure stack and gaining tensor IR compilation technology for custom silicon.

Qualcomm has agreed to acquire Modular for $3.9 billion, strengthening its position in AI infrastructure development. The acquisition grants Qualcomm access to Modular's tensor IR compilation technology, which will be used to advance custom silicon development for AI workloads.

Separately, OpenAI and Broadcom have unveiled a custom AI chip, signaling continued efforts to build proprietary silicon for AI model training and inference.

The moves reflect intensifying competition in custom AI chip development among major technology players. As cloud providers and AI companies seek to optimize performance and reduce dependency on third-party processors, acquisitions like Qualcomm's of Modular—and new chip announcements from OpenAI and Broadcom—underscore the growing importance of vertical integration in AI infrastructure. Compiler and optimization technology such as Modular's tensor IR has become a key differentiator for companies developing custom silicon to handle the demands of large-scale AI workloads.
