Qualcomm to buy AI startup Modular in $3.9B stock deal

Qualcomm ↘ 0.52% announced on Wednesday that it has agreed to acquire AI software infrastructure startup Modular Inc. in an all-stock transaction valued at approximately $3.9 billion, marking one of the chipmaker's largest bets yet on artificial intelligence beyond its core smartphone business.

Deal Details

Under the terms disclosed in a regulatory filing, Qualcomm will issue up to 19.2 million shares to Modular's equity holders when the transaction closes in the second half of 2026, subject to customary regulatory approvals. The $3.9 billion valuation is based on Qualcomm's Tuesday closing share price. Bloomberg had earlier reported the companies were in advanced talks for a deal valued at roughly $4 billion.bloomberg+3

The announcement coincided with Qualcomm's Investor Day 2026 in New York City, where CEO Cristiano Amon called the acquisition "a pivotal moment not just for Qualcomm, but for the AI industry".qualcomm

What Modular Brings

Modular was co-founded by Chris Lattner, the engineer behind LLVM, the Clang compiler, and Apple's Swift programming language. The company built an AI-native software stack that enables models to run across CPUs, GPUs, NPUs, and custom ASICs without code rewrites for each accelerator. In an industry where Nvidia ↘ 1.47% dominates AI software through its CUDA ecosystem, Modular's hardware-agnostic approach offers developers the ability to build once and deploy anywhere.wikipedia+1

"Joining Qualcomm gives us the scale and platform reach to accelerate that mission," Lattner said in the announcement. "Together, we can make AI development more accessible and performant for developers".qualcomm

Strategic Implications

The deal deepens Qualcomm's push into data center AI and diversification away from smartphone chips. It follows reports that the company is separately negotiating to acquire AI chip startup Tenstorrent in a deal valued between $8 billion and $10 billion. If both transactions close, Qualcomm would commit upward of $14 billion to reshaping its AI portfolio within weeks.investing

Amon framed the acquisition as part of a broader industry shift "toward disaggregated, multi-vendor architectures that demand a more open and modern software foundation". Qualcomm shares fell following the announcement.qualcomm
