AI Data Center Infrastructure
All research in AI Data Center Infrastructure — 10 reports.
GDS Holdings is China's leading carrier-neutral third-party data center operator, packaging power, cooling, and operations into long-term capacity leases across domestic facilities and its overseas DayOne interest. Normalized Q1 2026 revenue grew only 7.9%, while RMB 2.137 billion of RMB 2.652 billion in net income came from DayOne gains and net leverage was about 4.7x. Research rating Hold: AI orders are accelerating and the capital recycling loop is opening, but leverage and execution leave the margin of safety too thin.
SiTime is the only scaled MEMS precision-timing player globally, replacing quartz crystal oscillators at the physical-material level with silicon-based oscillators. Its MEMS segment share exceeds 80%, while AI data centers drove Q1'26 revenue up 88% and FY26 guidance to at least 80% growth, though the $3.2 billion acquisition of Renesas's timing business adds leverage, dilution, and integration uncertainty. Research rating Watch: a real moat and real growth, but the current price leaves little margin for error.
The pioneer of the AI data center copper interconnect category (Active Electrical Cable, AEC) and the leader with roughly 75% share. FY2026 revenue tripled to $1.335 billion, with a 68% gross margin, 35% GAAP net margin, $1.4 billion in net cash, and almost no debt—a connectivity picks-and-shovels play that is top tier on both quality and growth. Rating Watch: a superb business bought at a price that has already prepaid years of flawless growth, with tail risks from customer concentration and geopolitics holding it down.
The purest play on the AI server connectivity bottleneck, spanning four product lines (PCIe/CXL retimers, smart cable modules, CXL memory controllers, and the Scorpio fabric switch) plus the COSMOS software layer. It holds a de facto monopoly in Gen5 retimers, PCIe Gen6 already accounts for one-third of total revenue, FY2025 revenue hit $850 million (+115%), Q1 2026 reached $308 million in a single quarter (+93%), non-GAAP gross margin runs at 76%, GAAP has turned positive, and net cash sits near $1.2 billion. The business is a textbook chokehold. Rating Watch: a first-rate chokehold business priced so richly it leaves no room for any misstep.
A capital-intensive platform combining crypto mining, in-house mining-rig design, and AI data centers. The 2025 swing to a paper profit came mostly from fair-value changes in derivative liabilities; operating cash flow is deeply negative, Q1 2026 returned to a gross loss, and borrowings sit at roughly 1.9 billion dollars. The AI pivot remains an unproven option and the stock is not cheap. Rating Watch: an understandable business that is neither high-quality nor currently inexpensive.
A fast-expanding, strongly executing Bitcoin miner with 50 EH/s of hashrate and a 1.8 GW power pipeline, but where AI/HPC remains an unsigned option and the current price of USD 14.69 sits above our fair-value range. Rating Watch: a capable operator in a tough industry, not yet a business a long-term value investor can hold with confidence.
A heavy-capital infrastructure company running a dual engine of Bitcoin mining plus GPU/HPC, with hash rate reaching 25 EH/s, but free cash flow has been negative for years, share issuance dilution is heavy, and at the current price of $3.35 the stock already sits near its optimistic valuation. Rating Watch: an asset-backed, high-volatility option rather than a proven long-term compounder, with no obvious margin of safety at today's price.
A compound option spanning Bitcoin mining, Texas power-and-land assets, and an AI/HPC data-center pivot. With 2025 operating cash flow of -570 million dollars and roughly 64% share-count expansion over three years, the current price already prices in much of the transition and leaves an insufficient margin of safety. Rating Watch: a resource-rich optionality story that has not yet proven durable, high-quality owner earnings.
A small AI infrastructure company running two businesses, GPU cloud plus AI/HPC data center colocation, with revenue scaling fast but capex scaling faster, deeply negative FCF, heavy customer concentration, and majority control by parent Bit Digital; at roughly 11.6x P/S there is no margin of safety. Rating Watch: a high-uncertainty growth infrastructure name to track rather than own at today's price.
The second landing point of AI CapEx is shifting from a chip-centric model toward a rack-and-facility-centric one: GPUs and HBM carry the largest value but their profit leverage is already priced in, while order leverage and the profit pool are moving toward rack-scale integration, liquid-cooling core components (CDU, cold plate, QD), power distribution (transformers, PDU, UPS), high-power connectors, and short-reach copper cables. Priority names to track are Vertiv, Eaton, Schneider, Amphenol, HPE, Supermicro, Wiwynn, Quanta, Hon Hai, and Delta. Rating Watch: durable order and profit leverage is migrating from the chip layer to the boundary between the system layer and the facility layer.
