August is when institutional money quietly rotates. The Magnificent Seven trade is crowded, and the smart capital is moving one layer deeper into the AI stack: the fabricators, connectors, and power specialists that actually build the picks-and-shovels of the hyperscaler buildout. Goldman Sachs has flagged that AI-oriented companies were the most active issuers in the corporate bond market in 2025, and Morningstar estimates hyperscaler combined 2026 capex will be more than 4 times what the publicly traded US energy sector spends on exploration. That capital has to land somewhere. Here are three US-listed AI infrastructure names where institutional positioning is running well ahead of retail awareness.
Celestica (NYSE: CLS)
Celestica (NYSE:CLS | CLS Price Prediction) is the hyperscaler EMS story hiding in plain sight. The Q2 earnings report on July 27, 2026 was a decisive statement: revenue of $4.70 billion, up 62.4% year over year, with the Connectivity & Cloud Solutions segment posting $3.81 billion, up 84% year over year on hyperscaler AI demand. Adjusted EPS of $2.54 marked the fifth consecutive beat, and management raised full-year guidance to $20.5 billion in revenue and $11.30 in adjusted EPS, representing 65% revenue growth and 87% EPS growth. CEO Rob Mionis said, "Driven by our strong first-half performance, strengthening second half customer forecasts, and improved component supply, we are pleased to once again raise our 2026 annual outlook."
The setup is what makes this an August pick. Shares are at $331.44 after a 8.35% July pullback, yet the stock still trades 65.84% higher over the past year. Analyst positioning is lopsided: 95% bullish sentiment with 20 buy or strong-buy ratings versus one hold and zero sells, and a consensus target of $466.56 against a 52-week range of $173.23 to $474.02.
Risk: Customer concentration is real. If a single hyperscaler pushes an 800G or 1.6T program to the right, revenue can slip a quarter, and IEEPA tariff exposure remains an open question.
ON Semiconductor (NASDAQ: ON)
ON Semiconductor (NASDAQ:ON) is the post-trough recovery play with an AI kicker most investors still associate purely with autos. That perception gap is the opportunity. Q1 2026 delivered revenue of $1.513 billion, up 4.7% year over year, the first positive YoY print after a brutal cycle in which FY2025 revenue fell 15.35% to $6.00 billion. CEO Hassane El-Khoury was direct: "We exceeded expectations as demand strengthened through the quarter and we have moved beyond the cyclical trough on a path to recovery. Our AI data center business accelerated, growing more than 30% sequentially."
The AI data center line more than doubled year over year, and the Power Solutions Group posted $736.6 million, up 14% year over year. SiC and GaN traction is real: 900V EV architecture wins with Geely and NIO, plus GaN partnerships with Innoscience and GlobalFoundries for hyperscaler power delivery. Shares are $81.61, up 50.71% year to date but down 13.76% in July, offering a better entry than the June peak. Even the Polymarket crowd agrees the near term looks constructive, with a 95% implied probability of beating the next quarterly EPS report.
Risk: The rebuild has costs. Q1 2026 carried $329.3 million in restructuring charges, the Analog and Mixed-Signal segment is still down 5% YoY, and Barclays initiated at equal-weight with a $75 target citing China and auto exposure. Buybacks running 160% of free cash flow deserve scrutiny.
Astera Labs (NASDAQ: ALAB)
Astera Labs (NASDAQ:ALAB) is the purest AI connectivity bet in the market, and the Scorpio X-Series ramp is the catalyst investors should be watching this month. Q1 2026 revenue hit a record $308.36 million, up 93.4% year over year and 14% sequentially, with non-GAAP EPS of $0.61 marking the fourth consecutive beat. Operating cash flow surged 610.19% year over year to $74.6 million, and gross margins expanded to 76.3%. CEO Jitendra Mohan pointed to "robust demand for our PCIe 6 portfolio" as the growth engine.
The strategic story is bigger than one quarter. Astera is targeting the $20 billion merchant scale-up market by 2030, with the Scorpio X-Series 320-lane fabric switch entering production in the second half of 2026 and deep collaborations across UALink 2.0 and NVLink Fusion. Shares at $311.23 are up 87.08% year to date but down 27.77% in July, well off the 52-week high of $499.48. That drawdown, coupled with analysts lifting 2026 revenue forecasts roughly 13% to $1.3 billion, is the opening.
Risk: Valuation leaves no room for error. The P/E of 243, beta of 3.67, guided Q2 gross margin compression to roughly 73%, and $48.9 million per quarter of stock-based compensation mean any hyperscaler order slip gets punished quickly. Consider it a higher-beta expression of the same thesis CLS and ON offer at more grounded multiples.
What to watch in August: hyperscaler capex commentary during the tail end of Q2 earnings, any updated tariff guidance, and whether the July pullback in all three names finishes forming a base before institutional flows resume rotating down the AI supply chain.
