Masayoshi Son's DigitalBridge push funds AI buildout as 3 US stocks lag

The article frames the current AI moment around one man's infrastructure bet. Masayoshi Son's push to fund huge AI infrastructure projects through DigitalBridge is presented as evidence of how quickly the race for chips, cloud capacity and large language models is scaling up. That sets the backdrop for a search for value: capital is chasing the picks and shovels of the ChatGPT era, yet many AI-linked businesses still trade on undemanding valuations, and the article points to three underpriced US AI stocks from a screener while noting the full screen flags 44 more.

NVIDIA and Broadcom are the two names the article develops. NVIDIA develops data center AI computing platforms and GPUs, supplying chips, software and systems that power generative AI and advanced graphics; it generates about US$275.4b from Compute & Networking and US$27.6b from Graphics, with most sales coming from the United States and Taiwan, and a market cap of US$5.6 trillion. Broadcom supplies high-performance semiconductor connectivity and infrastructure software, linking AI accelerators, data centers and private clouds that run large language models, generating about US$59.4b from Semiconductor Solutions and US$29.7b from Infrastructure Software, with a market cap of US$1.7 trillion.

The swing factor the article emphasizes is what happens if a single key assumption about future AI infrastructure spending starts to fray. It quotes the view that uptake of an open-source, cheaper or better platform than NVIDIA's CUDA would heavily undermine its moat, and that a $400b revenue figure assumes data center customers continue to find sufficient revenue and financing to keep investing at pace. For readers weighing these stocks, the stakes appear to hinge on whether that spending assumption holds and whether a rival platform gains traction; both are framed as open questions rather than settled outcomes.
