Explore stocks on Coinbase

AI chip demand is surging, with Samsung and TSMC both reporting record figures tied to hardware for artificial intelligence. That kind of spending shows how quickly whole industries can open up when a powerful trend takes hold. Investors looking for companies that analysts expect to grow revenue and earnings strongly over the next 3 years may not want to sit on the sidelines. This article highlights 3 such stocks with solid balance sheets.

The three stocks below are just a starter pack. The full high growth screen surfaced 85 more companies with equally compelling stories that are not covered here. If you want to go straight to the source, use the Best high growth potential screener to identify, compare, and analyze the highest conviction ideas for your watchlist.

Credo Technology Group Holding (CRDO)

Credo Technology Group Holding plugs directly into the screener theme because its high-speed connectivity hardware and IP are built for the data traffic surge that AI and cloud workloads create, so the growth story hinges on how quickly customers upgrade to faster, lower power links.

Credo Technology Group Holding generates around US$1.6b from semiconductors, focused on high-speed connectivity solutions for Ethernet and PCIe, and has a market value of roughly US$41.4b.

"DustPhotonics' 1.6T platform directly enables Credo to compete in the CPO market, where chips and optical components are packaged together for maximum bandwidth and minimum power."

What happens to that growth profile if a single major buyer adjusts spending plans or pricing pressure shows up at the wrong moment.

If that concentration risk matters to you, the full narrative for Credo Technology Group Holding explains how Credo Technology Group Holding could keep accelerating even if one large buyer pauses purchases.

Ionic Digital (IOND)

Ionic Digital leans directly into the Best high growth potential theme through its high-performance computing and AI hosting, while still earning US$69 million from cryptocurrency mining and related activities, and it carries a market value of about US$3.7b.

Ionic Digital plugs into the same AI infrastructure story as the rest of this list, but from a different angle, renting out power and capacity rather than designing chips, which is why the long-term leasing side of the business matters so much for this screen.

"Conversion of 323MW at Ward County into a 10 year triple net lease with contracted rent of about US$183m a year and 3% annual escalators after year 5 sets up Ionic Digital for a larger share of revenue from long dated, high margin leasing income."

What really determines how much of that potential turns into durable earnings is one unresolved factor around how concentrated that lease stream remains over time.

That concentration question is exactly what full narrative for Ionic Digital unpacks, revealing how Ionic Digital could widen its earnings base while keeping that contracted lease income accelerating.

Lumentum Holdings (LITE)

Lumentum Holdings is plugged directly into the Best high growth potential theme through the high-speed optical components that sit behind cloud and AI data centers, while still running a broader photonics business that spans telecom networks, consumer sensing, and industrial lasers, generating about US$3b from its Integrated Enterprise segment on a roughly US$100.6b market value.

Lumentum Holdings gives this screener real teeth for AI infrastructure because its high-speed optics are the physical link that lets GPU clusters talk to each other at scale.

"The core submarket that matters most for long-term value is high-speed optical components for cloud and AI data centers, where bandwidth demand from GPU clusters is driving a rapid upgrade cycle to 800G and 1.6T optics."

What investors really need to watch is how one subtle shift in demand and pricing power shapes the gap between today's expectations and tomorrow's margins.

That margin gap is exactly what the full narrative for Lumentum Holdings unpacks, showing where Lumentum Holdings could see earnings power accelerating faster than headline demand suggests.
