Trump Greenlights the Supercycle: 3 Stocks at the Heart of AI Infrastructure

The hook is a live phone call on stage at the All-In Summit. Donald Trump gets Jensen Huang on the line and describes data centers as the oil of the next 20 to 25 years, a force that makes states and people wealthy and even bigger than the internet itself, adding he will not let opponents of the buildout stand in the way. Huang answers on speaker and agrees. The presenter frames the exchange less as political theater and more as a green light for an industrial buildout at massive scale.

The Physical Bottleneck: Not Software

The core argument is that the brake is physical, not algorithmic. Hyperscalers are said to be deploying about 700 billion dollars of capital expenditure this year, and Moody's research cited by sector coverage puts the six largest US hyperscalers near that level, with demand outstripping supply and power availability plus build times constraining capacity through 2027. High-density AI clusters are described as drawing up to four times the power of legacy farms, turning thermal management into the top operational headache and making standard hardware inadequate as clusters scale to tens of thousands of GPUs and latency becomes the new wall.

From that diagnosis the video narrows to three layers: high-efficiency liquid cooling and critical power management to keep mega sites alive, baseload nuclear and clean-energy infrastructure to secure long-term purchase agreements for the grid, and high-speed interconnect silicon to keep data flowing across enormous server fabrics. The recent September pullback is cast as a temporary window into three under-the-radar names sitting at the center of what is called a 25-year economic engine, each presented as hard to bypass.

Astera Labs (ALAB) — Connectivity Silicon

Astera Labs focuses on the bandwidth and power choke that appears when clusters grow from a few thousand to tens of thousands of nodes and copper falls short. Its intelligent connectivity platform pairs Aries retimers, Taurus cable modules and Leo memory controllers with the Scorpio smart fabric switch family and the Cosmos software suite, spanning PCIe, CXL and active electrical cables plus 200G-plus Ethernet for scale-up and scale-out fabrics. While Nvidia dominates GPUs, the case made is that interconnect specialists trade at lower structural market caps relative to multi-year compound growth tied to the data-center build race.

In Q2 2026 Astera Labs posted record revenue of 392.4 million dollars, up 104% year over year and 27% sequentially, beating consensus by about 32 million dollars. GAAP gross margin was 73.3%, GAAP net income 153.1 million dollars and GAAP diluted earnings 0.83 dollars; non-GAAP diluted earnings were 0.80 dollars versus 0.69 expected and non-GAAP net income 145.8 million dollars. Guidance for Q3 2026 is 540 to 560 million dollars, roughly 40% sequential growth, with a 400 basis point lift in operating margin to 43%. Scorpio X is expected to become the largest product family early and to carry over 1,000 dollars of content per XPU in future platforms, with UALink platforms and high-density fiber-attached optics extending the 2027 pipeline. Valuation looks premium at 75.4 times year-one earnings and 43.4 times forward earnings, compressing to 47.6 times in year two and 37.6 times in year three on about 53% earnings growth, with roughly 27 times enterprise value to sales and a 1.44 times PEG. Consensus sketches a 320 dollar target on 2027 earnings of 6.39 dollars at a 50 multiple, with a second marker discussed around 0.88 dollars for 2028.

Vertiv (VRT) — Power and Liquid Cooling

Vertiv is cast as the backbone for power and thermal at a time when rack density is leaping from single-digit kilowatts to 300 kilowatts and even 1 megawatt per rack, forcing a move from air to end-to-end liquid cooling, 800-volt DC distribution and grid-to-chip integration. Its Cool Chip coolant distribution units, SmartRun modular units and the 1.45 billion dollar acquisition of Utility Innovation Group for microgrid and interconnection orchestration lift content per megawatt toward 3.25 to 3.75 million dollars.

In Q2 2026 Vertiv reported net sales of 3.274 billion dollars, up 24% year over year with 18% organic growth; operating profit was 638 million dollars up 44% and adjusted operating profit 738 million dollars up 51%, with adjusted margin 410 basis points wider at 22.6%. Adjusted diluted earnings were 1.52 dollars up 60% (diluted 1.27 dollars up 53%), beating guidance by 12%. Adjusted free cash flow was 925 million dollars up 234% with cash conversion above 150% and about 5.6 billion dollars of liquidity, ending in a net cash position. Backlog hit a record 15.0 billion dollars with a book-to-bill of 2.9 times and deferred revenue doubled to 3.63 billion dollars from 1.81 billion within six months. Full-year 2026 guidance was raised to about 14.0 billion dollars of net sales with about 37% growth, adjusted operating profit 3.325 billion dollars at a 23.8% margin, adjusted earnings 6.65 to 6.75 dollars with about 60% growth and adjusted free cash flow 2.5 billion dollars. Multiples sit at 38.16 times 2026 consensus of 6.71 dollars, 28.13 times 2027 on 9.10 dollars, 22.15 times 2028 on 11.56 dollars and 18.67 times 2029 on 13.71 dollars; the 1.01 times forward PEG is framed as a 35% discount to peers. The Wall Street target of 338 dollars implies about 26% upside, while the served data-center market is modeled from 31 billion dollars in 2026 toward 700 billion by 2034 at an 11% compound rate.

Constellation Energy (CEG) — Nuclear Baseload

Constellation operates the largest nuclear fleet in the United States, about 55 gigawatts, and the presentation stresses that rebuilding that fleet would cost more than three times current enterprise value, creating a scarcity moat. Around-the-clock carbon-free demand from hyperscaler campuses is tightening regional grids, making existing nuclear assets and grid-connected capacity hard to replicate. Federal nuclear production tax credits provide an inflation-linked floor up to 15 dollars per megawatt hour through at least 2032, with 25 million dollars recognized in the first half of 2026, and a 3% inflation path versus a 2% base is estimated to add about 0.30 dollars to 2030 base earnings.

In Q2 2026 Constellation reported GAAP earnings of 1.42 dollars per share and adjusted operating earnings of 2.55 dollars, up from 1.91 dollars a year earlier, about 34% higher. Full-year adjusted guidance was lifted to 11.50 to 12.50 dollars. Operating cash flow for the first six months was 1.55 billion dollars, with 697 million dollars of cash (1.08 billion including restricted) against 19.11 billion dollars of long-term debt. Catalysts include the Calpine acquisition adding 920 megawatts of contracted capacity worth 145 to 360 million dollars of annual premium revenue and 0.37 to 0.92 dollars of annual earnings, and the restart of the Crane Clean Energy Center at Three Mile Island in the second half of 2027 backed by a 20-year purchase agreement with Microsoft for roughly 835 megawatts of carbon-free power. The company targets over 20% base earnings growth from 2026 through 2029 and a sustained double-digit compound rate into the 2030s, with a 5 billion dollar buyback where 2.2 billion has been spent adding 0.20 to 0.75 dollars to 2029 earnings. The stock trades around 22.7 times the 2026 midpoint and 23.5 times forward earnings, and a 2029 model of 17.25 dollars at a 20 multiple sketches a 345 dollar target.

Portfolio Takeaway: Spine of a 25-Year Engine

The closing case is that the AI build is moving from software promises to physical reality, and that Astera Labs, Vertiv and Constellation together form the mandatory spine powering a quarter-century engine. The September volatility pullback is presented as a chance to position before Wall Street fully prices the next wave of deployment. My reading is to avoid collapsing the story into a single ticker and instead track each bottleneck separately, weighting balance-sheet discipline and contracted visibility rather than treating all three with the same brush.
