The densest AI racks need liquid cooling. Vertiv (VRT), nVent (NVT) and Modine (MOD) sell the infrastructure.
Vertiv, nVent and Modine all sell into the AI liquid-cooling shift, but their growth, margins and customer concentration are not the same. A sourced, company-by-company comparison.
AI GPU arrives in weeks. The power gear behind it takes years: GE Vernova (GEV), Vertiv (VRT), Eaton (ETN), Quanta (PWR) and Powell (POWL)
The chip is the easy part. Data centers are stuck waiting on turbines, transformers and switchgear that take years to build. Here's what GE Vernova, Vertiv, Eaton, Quanta and Powell each sell into that shortage, and how big their order books have gotten.
Nebius (NBIS) soars 27% as explosive AI demand burns Michael Burry's short
Nebius grew Q2 revenue 454% to $582 million, swung to a profit, and jumped about 27% as CEO Arkady Volozh said AI demand keeps growing exponentially. The whole data center trade rallied, and Michael Burry's fresh short went underwater.
The AI trade rallied Monday. Memory fell as much as 8% at the open even as chip prices kept rising.
Micron (MU) has lost a third of its value since June 25 and SanDisk nearly half. CoreWeave and Vertiv fell about half as far, and Nvidia rose. Memory contract prices never fell. What changed is the rate of increase, which went from 93-98% a quarter to a forecast 13-18%.
The new US import ban covers cotton, tomatoes, and the capacitor supply chain behind AI servers
DHS added 43 Chinese companies to the UFLPA Entity List on July 31, 2026. Two of them sit in the aluminum electrolytic capacitor chain, the parts that fill AI server power supplies. Nichicon and Nippon Chemi-Con had already raised prices in June, citing aluminum foil costs.
Micron (MU), SK Hynix and AMD just gave chip stocks their first back-to-back gain in two weeks (July 21, 2026)
Micron (MU) closed up about 12 percent, SK Hynix's ADR about 14 percent, and AMD 8 percent Tuesday, chip stocks' first back-to-back gain in two weeks. A Bank of America upgrade on memory demand and a new AMD-Microsoft Azure deal did the heavy lifting.
Jim Cramer's tech calls are still lagging the rest of his book. Intel is 1 for 5, and IBM crashed the day after his second buy call.
Jim Cramer's tech calls are still his weak spot. Intel is 1 for 5 since June, IBM is down nearly 30% since his back-to-back buy calls, and his tech picks trail the Nasdaq-100 by more than three points a call even after Tuesday's chip bounce.
I gave five AIs a pretend $10,000 to pick 5 tech stocks. Four bought Nvidia (NVDA). Claude went rogue.
ChatGPT, Gemini, Grok, Meta AI and Claude each picked five tech stocks to hold for six months. Four bought Nvidia. Claude went the other way. Every pick is here and the scoreboard runs monthly.
New York froze new data centers for a year, and TeraWulf just became the day's biggest loser because of it. Nebius, close behind, has nothing to do with New York.
Governor Hochul signed a first-in-the-nation moratorium on new hyperscale data centers today, and TeraWulf (WULF) fell 6.7%, the hardest hit in the group, because it owns exactly the kind of project the order targets. Nebius (NBIS) fell almost as much, and Digital Realty (DLR) also dropped on real New York exposure, but Nebius and CoreWeave (CRWV) have nothing to do with Albany.
Chips got smoked today. Tomorrow's CPI report at 8:30am decides what happens next.
Arm, Coherent, Micron, AMD and Nvidia fell between 3.5% and 7.5% Monday while Microsoft, Apple and Amazon finished green. The selling stayed inside crowded AI infrastructure names. Tuesday's 8:30am CPI report could send the same stocks sharply either way, and the real risk isn't even in the data yet.
We built a stock score tool. It gave Intel a D, and I bought the stock anyway.
One pick in every layer of the AI hardware stack, each one graded by the SEC-filings scoring tool we just built. Four picks agree with the tool: NVDA, WDC, TSM, VRT. Micron is a partial. INTC and COHR do not agree with the tool at all, and I am holding both anyway.
Inside the AI hardware stack, from Nvidia's chips to the grid that powers them
An AI data center is seven layers of hardware: GPUs, memory, storage, CPUs, networking, manufacturing, and power. Here's the full map, with the public companies behind each layer and where the bottlenecks actually are.
The AI stocks that led and lagged the first half of 2026
The first half of 2026 split the AI trade in two. Memory and chip-supply names like Micron (MU, +304%) and Intel (INTC, +278%) soared, while marquee names lagged and AI software fell, with Palantir (PLTR) down about 34%. Here is the full scoreboard and what it means.
AI's quiet winners: ASML, AMD and Vertiv VRT lead at the June 30, 2026 open
On the last trading day of the first half, the AI suppliers led again. ASML, Arm (ARM) and Vertiv (VRT) each rose about 4%, while Micron (MU) is up roughly 300% in 2026.
Data-center and bitcoin-miner stocks (CRWV, HIVE) sold off at the open on June 29 after a pre-market pop
AI data-center, neo-cloud, and bitcoin-miner stocks ticked up pre-market on June 29, then sold off hard at the open. Most are down 3% to 10% from the open and now slowly recovering. Nebius (NBIS) was the exception.
The AI shortage keeps moving: from GPUs to memory, and now to hard drives (STX, WDC)
The AI shortage keeps rotating down the supply chain: first GPUs, then compute and networking, now memory, and hard drives are the leg lighting up next. The pattern, the stock moves at each stage, and what could be next.
The AI stock map: every layer of the trade, from sand to software
A top-to-bottom deep dive on the AI supply chain, from the machines that make the chips down to the hyperscalers writing the checks, and how every layer pushes and pulls on the others.
