3 AI Infrastructure Stocks Retail Investors Are Researching After The OpenAI News

OpenAI’s latest model release has put fresh attention on every stock tied to AI and machine learning, and the commentary from Jim Cramer has only turned up the volume. This kind of spotlight can pull capital quickly toward companies that appear plugged into the trend, leaving slower movers watching from the sidelines. In this article you will see three stocks from our AI & Machine Learning Enablers screener that are squarely in the crosshairs of this news.

The three stocks that follow are only a starter set from this idea, since the full screen surfaced 69 more companies with equally compelling narratives that do not fit into one article. To see the rest, head straight into the Artificial Intelligence (AI) & Machine Learning Enablers screener to analyze, filter, and identify which AI and machine learning enablers deserve a spot on your watchlist.

Cerebras Systems (CBRS)

Cerebras Systems is one of the purest plays on AI infrastructure in this screener, supplying the wafer-scale chips and racks that power demanding generative AI and inference workloads for hyperscalers and enterprises worldwide.

Cerebras Systems generates about US$680.7 million from semiconductors tied directly to its AI compute platform and carries a market value of roughly US$49.9b, putting it among the larger pure-play AI infrastructure stocks.

"In late 2025, Cerebras signed a transformative Master Relationship Agreement with OpenAI, which is contractually bound to procure 750 megawatts of inference capacity through 2028, backed by a $1.0 billion working capital loan to fund Cerebras's manufacturing scale-up."

What happens to future margins and cash flow depends heavily on how a single concentrated customer relationship evolves from here.

That customer concentration cuts both ways, and the full narrative for Cerebras Systems shows how Cerebras Systems could turn it into accelerating scale, optionality, and bargaining power beyond this single contract.

Z.AI (SEHK:2513)

Z.AI builds and deploys customised large AI models for clients across China, matching the screener’s focus on real-world AI and machine learning enablers. It generated about CN¥500.9 million from on-premise deployment and CN¥986.5 million from cloud-based services, and carries a roughly HK$426.5b market value.

Z.AI sits directly in the flow of demand for large language models, selling both on-premise and cloud tools that help clients run and tune their own AI systems. Investors watching the OpenAI news may focus on how one unresolved funding and profitability trade off shapes pricing power, customer appetite and long-term growth potential.

That funding trade off is exactly what the 2 key rewards and 1 important major warning sign unpacks, so you can see where Z.AI’s opportunity could be accelerating or stalling next.

Teradyne (TER)

Teradyne plugs into the AI & Machine Learning Enablers theme by supplying the automated test systems that help qualify complex AI chips before they reach data centers, phones, and cars. This makes its recent momentum in AI hardware testing particularly important.

Teradyne designs automated test equipment and robotics, with about US$3.7b from Semiconductor Test, US$386 million from Product Test, and US$356 million from Robotics, and the stock carries a roughly US$55.8b market value.

"Teradyne expects significant future growth potential from AI accelerators, robotics, and semiconductor automation, which are being driven by long-term industry themes such as AI, verticalization, and electrification."

What happens if one key piece of AI testing demand does not grow as aggressively as the current expectations built into those plans?

If that AI testing demand rerates slower or faster than expected, the full narrative for Teradyne lays out how Teradyne’s automation story could still be quietly accelerating.
