Qualcomm is nearing a deal to acquire Modular, an AI software startup, for roughly $4 billion, Bloomberg reported. The talks are at an advanced stage, according to the report, but neither Qualcomm nor Modular has confirmed the discussions, and the terms could still change.

The purchase would move Qualcomm, long known for the processors inside smartphones, deeper into the data-center market, where demand for chips that run generative AI is surging. Qualcomm has said it plans to ship AI accelerators and data-center chips by the end of this year.

What Modular does

Modular was founded in 2022 by Chris Lattner, its chief executive, and Tim Davis, its president. Lattner is widely known in software circles as the creator of the Swift programming language and of LLVM, a compiler toolchain that underpins much of modern software. The company builds two main products: the MAX inference platform, a suite of tools for serving AI models, and Mojo, a programming language pitched as a faster superset of Python aimed at machine-learning workloads.

The stated goal is portability. Modular's platform is designed to run popular AI models across different chips — Nvidia GPUs, AMD GPUs, CPUs and others — without forcing developers to rewrite their code for each piece of hardware.

Why software portability matters

"Inference" refers to the stage at which a trained AI model is actually used to generate answers, as opposed to the earlier, costlier "training" stage. As AI deployment scales, inference accounts for a growing share of computing demand — and of the market chipmakers are competing for.

Nvidia's dominance rests not only on its hardware but on CUDA, the proprietary software platform developers use to program its GPUs. Because a vast body of AI code is written for CUDA, customers face high switching costs, an effect often described as developer lock-in. Software that can move AI workloads across rival chips threatens that advantage, which is why the inference layer has become a competitive battleground among chipmakers.

Fit with Qualcomm's data-center push

The acquisition would pair Modular's software with Qualcomm's emerging accelerator roadmap. It follows Qualcomm's reported talks to supply custom AI chips to ByteDance, the owner of TikTok, for its data centers — a deal Boursel has covered. Buying a hardware-agnostic software layer would let Qualcomm offer customers a full stack rather than chips alone.

Funding and valuation

Modular has raised about $380 million in total, including a $250 million round in September 2025 that valued the startup at roughly $1.6 billion. At the reported price, Qualcomm would be paying more than double that valuation in well under a year — a measure of how strategically chipmakers now view the software that decides which hardware AI runs on.

The outcome will be watched as a test of whether challengers can chip away at Nvidia's software advantage. For now, it is reported talks, not a signed deal — and, as Bloomberg cautioned, the terms could still shift or fall through.
