Before the Next Nvidia-Style Run, Here Are 3 AI Stocks Worth Watching

The article highlights three AI infrastructure names—Astera Labs, Marvell, and Credo—positioned to benefit from rising demand for high-speed connectivity as AI spending shifts from training to inference and scale-up networking. Astera posted Q1 fiscal 2026 revenue of $308.4 million, up 93% year over year, while Marvell guides fiscal 2027 revenue to nearly $11 billion and Credo reported Q3 fiscal 2026 revenue of $407 million, up 201% year over year. The piece is broadly bullish on AI networking, but it is commentary rather than a new catalyst, so near-term market impact is limited.

Analysis

The market is still underpricing how quickly AI capex is migrating from compute to interconnect. Once clusters scale past a few thousand accelerators, bandwidth, power, and failure rates become the binding constraint, which shifts value from the obvious GPU layer into the less glamorous “picks and shovels” of connectivity. That creates a multi-year attach-rate expansion story for ALAB, MRVL, and CRDO, but also means the best phase of the trade may be when deployment intensity remains high while the market is still focused on chip revenue.

Among the three, ALAB has the cleanest operating leverage because its products sit directly on the critical path of each incremental AI server buildout, and its revenue per processor framing suggests a meaningful wallet-share expansion if NVLink-adjacent designs become standardized. MRVL is the more strategic but lower-upside-quality version of the same theme: its optionality is broader, but it is also more exposed to customer build-versus-buy decisions at hyperscalers, so the stock may trade more like a platform consolidator than a pure growth compounder. CRDO has the sharpest near-term velocity, but its economics are most vulnerable to customer concentration and product transitions; if one hyperscaler pauses spending, the multiple can compress much faster than fundamentals deteriorate.

The consensus is treating this as a simple “AI networking” growth basket, but the second-order winner is likely whichever company converts from point products into architecture lock-in. That favors firms that can become embedded in reference designs, because once a network topology is standardized, switching costs rise sharply and gross margin durability improves. The main risk is not demand collapse; it is a digestion phase in 2H26/2027 if hyperscalers pause to integrate prior capacity, which would hit the higher-multiple names first even if the secular trend stays intact.

Key Decisions for Investors

• Go long ALAB on any post-earnings pullback of 8-12% over the next 2-4 weeks; best risk/reward in the group if Scorpio adoption continues because the market is likely underestimating mix-driven margin expansion.
• Use MRVL as a 6-12 month relative-value long versus a basket of semiconductor names with less AI networking exposure; upside is slower but more durable if custom silicon plus optical scale into a standard platform role.
• Trade CRDO as a tactical momentum long only with a tight stop or via call spreads into the next 1-2 quarters; it has the fastest revenue growth but the highest multiple and customer-concentration risk, so position sizing should be smaller than ALAB/MRVL.
• Pair long ALAB / short a broad semiconductor benchmark for 3-6 months to isolate interconnect share gains from general AI capex beta; this should work if data-movement spend keeps outgrowing compute spend.
• Avoid chasing all three after a strong run; wait for guidance-driven resets because these names are most vulnerable to any hint of hyperscaler digestion even when long-term thesis remains intact.
