Top 3 AI Stocks To Watch In September 2026

Bond markets are flashing a blunt message. Long term Treasury yields have climbed to levels last seen in 2007 as investors demand higher compensation for funding a historic wave of AI related investment. Higher discount rates can punish richly priced growth stories, which puts extra focus on companies helping power the ChatGPT driven AI buildout yet priced more modestly. This piece highlights three such undervalued AI stocks worth knowing about.

The stocks covered below are just a starter pack for the AI theme, and the wider screen surfaced 47 more companies with equally compelling stories that are not included in this article.

If you want to identify, compare and analyze the highest conviction AI plays powering ChatGPT and related infrastructure, head straight into the Undervalued Artificial Intelligence/ AI Stocks screener.

Adobe (ADBE)

Adobe has become one of the clearest software plays on the AI creative boom, weaving Firefly and other generative tools directly into the Creative Cloud workflows that designers, marketers, and enterprises already rely on worldwide.

Adobe Inc. is a US$91.6b software group best known for Creative Cloud, now embedding generative AI through Firefly across design, imaging, and document tools. The company reports revenue across regions including EMEA at US$7.1b and Asia-Pacific at US$3.6b.

"As professionals integrate AI into their daily workflows, their credit usage increases. When they hit the limits of their current plan, the path of least resistance is to upgrade to a higher Creative Cloud tier or purchase a credit pack, thereby driving Average Revenue Per User (ARPU) expansion."

What happens to Adobe’s earnings profile if a single assumption about how deeply enterprises embed these AI tools into everyday workflows breaks?

If that assumption matters to your thesis, read the full narrative for Adobe to see how different AI adoption paths could reshape Adobe’s risk and reward profile.

Broadcom (AVGO)

Broadcom is a heavyweight in the AI infrastructure story, supplying the plumbing that lets large models actually move data, talk to storage, and communicate across giant data centers.

Broadcom Inc. builds semiconductor hardware and infrastructure software that underpin AI data centers, with AI-linked networking chips and custom silicon housed in its Semiconductor Solutions division. That segment generated about US$59.4b, while Infrastructure Software added roughly US$29.7b, and the business is valued at around US$1.68t.

"Broadcom is generating substantial free cash flow, expanding its custom silicon business, strengthening its position in networking, and integrating software assets that further diversify earnings."

One potential risk is a quiet shift in AI customer appetite for custom chips that could influence how much Broadcom can keep turning that cash into future growth.

That quiet shift in custom chip demand is exactly where the story gets interesting, so read the full narrative for Broadcom to see how Broadcom’s AI cash engine could evolve next.

Oracle (ORCL)

Oracle is now widely watched for how Oracle Cloud Infrastructure can power large language models for enterprises, while still anchoring its business in core databases and business software that already sit deep inside corporate IT stacks.

Oracle runs a broad enterprise IT platform, from Fusion business applications and databases to hardware, with Cloud and software bringing in about US$62.8b, Services about US$5.8b, and Hardware about US$3.2b, and the group valued at roughly US$414.6b.

For this screener, Oracle matters because its Oracle Cloud Infrastructure and managed AI services give enterprises a way to run generative AI and ChatGPT style workloads next to the databases and applications they already trust, tying AI more directly to day to day business processes.

"In 2024, OpenAI made headlines by expanding its cloud footprint to include Oracle Cloud Infrastructure (OCI), a move described as strategic, reflecting the growing demand for massive compute power and the need for multi-cloud resilience."

What happens to Oracle’s AI story if one pressure on how fast that new cloud capacity turns into profitable, cash-backed usage shifts.

That pressure point is exactly where Oracle’s AI story can accelerate, so read the full narrative for Oracle to see how multi cloud demand may reshape the upside.
