Market research firm Dell’Oro Group reported that worldwide data center capital expenditure moved higher in the first quarter of 2026, attributing the increase to two forces working in tandem: continued buildouts of AI infrastructure and inflation in memory costs. The finding, published June 10, 2026, comes from the firm’s ongoing tracking of data center IT and infrastructure spending.

The headline pairing matters. It signals that the capex surge is being driven not only by more servers, accelerators, and facilities being deployed, but also by each unit of that equipment costing more — a distinction with real consequences for how the numbers should be read.

Executive Summary

Dell’Oro Group’s first-quarter 2026 reading extends a multi-year run of elevated data center spending tied to artificial intelligence. Capex — capital expenditure, the money operators sink into servers, networking gear, storage, and the facilities that house them — climbed again in the quarter, with AI infrastructure named as the primary engine and memory cost inflation as a significant amplifier.

The memory angle is the notable wrinkle. High-bandwidth memory (HBM) and conventional DRAM are essential inputs to AI servers, and when their prices rise, total spending rises even if unit volumes were flat. Dell’Oro’s framing suggests both effects are in play: operators are buying more, and paying more per unit of what they buy.

For the infrastructure industry, the read-through is that the AI spend cycle is broadening rather than cresting. Spending strength that persists into 2026 — after two years in which skeptics repeatedly called a peak — keeps demand signals strong for chipmakers, memory suppliers, server OEMs, colocation providers, and the power and cooling ecosystem behind them.

Broadening, Not Peaking

Every quarter of continued capex growth is a data point against the “AI bubble about to deflate” thesis — and a data point that must itself be scrutinized. A first-quarter increase in 2026 means the hyperscalers and large AI builders entered the year still accelerating, not digesting. Historically, capex cycles in IT infrastructure end with a visible plateau in quarterly spending before the decline; Dell’Oro’s reading indicates that plateau has not yet arrived.

The word “broadening” is doing real work here. Early AI capex was concentrated in a handful of hyperscale cloud providers. As the cycle matures, spending typically spreads to second-tier cloud operators, GPU-cloud specialists, enterprises building private AI capacity, and sovereign or national AI initiatives. A quarter in which growth continues at scale is consistent with that widening base of buyers, though the release headline alone does not break out who spent what.

Memory Inflation: Growth With an Asterisk

The second driver Dell’Oro names — memory cost inflation — deserves careful reading. Memory (DRAM for general computing, and especially high-bandwidth memory stacked directly alongside AI accelerators) has been in tight supply as AI demand outstripped what the small number of memory manufacturers could produce. When memory prices rise, every AI server costs more, and aggregate capex inflates mechanically.

That means dollar-denominated capex growth overstates the growth in deployed computing capacity. An analyst comparing 1Q 2026 spending to a year earlier is partly measuring more infrastructure and partly measuring more expensive infrastructure. For memory suppliers this is a windfall; for buyers it is margin pressure; for anyone using capex as a proxy for AI capacity coming online, it is a reason to discount the headline number somewhat. Dell’Oro’s decision to name inflation explicitly as a driver is a useful piece of intellectual honesty in a market prone to reading every big number as pure demand.

Winners Along the Supply Chain

The beneficiaries of this spending pattern are ordered by scarcity. Memory manufacturers sit at the top: rising prices on constrained supply flow almost directly to their revenue. Accelerator vendors and the server OEMs that integrate them continue to ride volume growth. Behind the IT equipment, the physical layer — data center developers, colocation operators, power equipment makers, and cooling specialists — benefits from every incremental megawatt the AI buildout requires, and their revenue tends to lag IT capex, meaning a strong 1Q 2026 for equipment implies continued facility demand into 2027.

The squeezed parties are buyers without pricing power. Smaller cloud providers and enterprises paying inflated memory prices face a worse cost position than hyperscalers, who negotiate supply agreements at scale. If memory inflation persists, it acts as a regressive tax on the smaller end of the AI market — one more force concentrating AI capacity among the largest players.

The Risk Ledger

None of this eliminates cycle risk. Capex is a leading indicator of expected demand, not proven demand: the spending only pays off if AI services generate revenue commensurate with the infrastructure behind them. Input-cost inflation adds a second risk — cycles fed partly by price increases can unwind sharply when supply catches up and prices normalize, as memory markets have done repeatedly across their history. And the physical constraints on the buildout, chiefly electric power availability, remain unresolved in many markets.

The balanced read: 1Q 2026 confirms the AI infrastructure cycle remains in its expansion phase, while the memory-inflation component is a reminder to separate dollars spent from capacity gained before drawing conclusions about either demand or durability.

Background

Data center capex has been the defining economic story of the AI era. Since large language models triggered an infrastructure race in 2023, the biggest cloud and AI companies have committed historically unprecedented sums to accelerated computing — spending that flows through chipmakers and server vendors into land, buildings, power, and cooling. Independent trackers like Dell’Oro Group, which has analyzed telecom and data center equipment markets since 1995, provide the industry’s scorecard for whether that race is accelerating or cooling.

Memory has emerged as the cycle’s chokepoint. Production of high-bandwidth memory is concentrated among a handful of manufacturers, and AI demand has kept supply tight, pushing prices upward across memory categories. That inflation now shows up directly in aggregate capex figures — making 2026 the year analysts must ask not just how much the industry is spending, but how much of that spending buys new capacity versus simply covering higher input costs.

S&P Global, the ratings and market-intelligence firm, reported that AI infrastructure results for 2025 topped its expectations and, on the strength of those results, has upgraded its forecast for the sector. The announcement, published May 7, 2026, signals that one of the most closely watched independent forecasters now sees more AI-driven data center, compute, and power investment ahead than it previously modeled.

Executive Summary

Forecast upgrades come in two flavors: those driven by sentiment and those driven by results. S&P Global’s revision belongs to the second category — the firm says actual 2025 outcomes in AI infrastructure exceeded what its prior models anticipated, and it has raised its outlook accordingly. That distinction matters. A results-based upgrade means the checks cleared: capital was deployed, capacity was delivered or contracted, and revenue showed up in reported financials rather than in investor-day slideware.

For the infrastructure ecosystem — data center operators, connectivity providers, power utilities, and the vendors that supply them — an independent forecaster moving its baseline upward extends the planning horizon for an already historic buildout. It also raises the stakes: the higher the consensus forecast climbs, the more painful any eventual shortfall in demand, power availability, or financing would be. The syndicated headline, however, carries no figures, so the size of the beat and the magnitude of the upgrade remain to be read in the underlying report.

An Upgrade Anchored in Results, Not Hype

Throughout the AI investment cycle, skeptics have argued that spending projections rest on circular enthusiasm — model builders forecasting demand for their own models. What distinguishes this announcement is its direction of inference: S&P Global is looking backward at 2025 actuals and concluding its earlier numbers were too low. When realized results outrun a forecast, the forecaster faces a choice between treating the beat as a one-time pull-forward of demand or as evidence the underlying trend is steeper. By upgrading, S&P Global has chosen the second interpretation.

That said, extrapolation is exactly how forecasters get caught at cycle peaks. Strong 2025 results confirm that money was spent and capacity absorbed; they do not by themselves prove that the returns on that spending will justify the next round. Readers should distinguish between the fact of the beat — which is evidence — and the upgraded projection, which remains a model.

What More Capex Means for Power and Land

AI infrastructure is shorthand for a physical supply chain: chips, servers, the data centers that house them, the fiber that connects them, and — increasingly the binding constraint — the electricity that powers them. A raised forecast implies more of all of it. For data center markets already contending with multi-year utility interconnection queues, transformer lead times, and community pushback on siting, an upgraded demand outlook translates directly into more competition for powered land and grid capacity.

For utilities and power developers, a higher independent forecast strengthens the case for generation and transmission investment that regulators must approve. For enterprise and colocation buyers, it points the other way: sustained demand above prior expectations tends to keep vacancy low and pricing firm, meaning tenants who deferred capacity decisions waiting for the market to loosen may be waiting longer than they planned.

Winners, Losers, and the Widening Gap

A rising forecast does not lift all boats equally. Operators with secured power, entitled land, and access to capital can convert an upgraded outlook into pre-leased expansion. Smaller players without those ingredients face the same rising input costs — power, equipment, construction labor — without the contracted revenue to offset them. The upgrade also sharpens the divide between markets: regions that can deliver megawatts on credible timelines will absorb a disproportionate share of the incremental demand the new forecast implies.

The risk ledger deserves equal attention. Every upward revision embeds assumptions about continued hyperscaler spending, stable financing conditions, and AI applications generating enough end-customer revenue to sustain the cycle. If any of those assumptions weakens, capacity ordered against the upgraded forecast could arrive into a softer market. S&P Global’s own ratings business exists precisely because leverage built in good times gets tested in bad ones — a useful lens to apply to its market forecasts as well.

Background

The AI infrastructure buildout accelerated sharply after generative AI reached mass adoption, with hyperscale cloud providers and AI developers committing historic sums to chips, data centers, and power. Throughout 2024 and 2025, a running debate pitted those who saw the spending as a durable platform shift against those who warned of overbuild, with independent forecasters like S&P Global serving as referees between the narratives.

S&P Global occupies an unusual vantage point in that debate: its ratings arm evaluates the creditworthiness of the utilities, data center operators, and technology firms doing the spending, while its market-intelligence arm models the demand itself. When a firm with exposure to both sides of the ledger raises its outlook based on realized results, it carries more weight than promotional projections — which is precisely why the details behind this upgrade merit close reading.

Data Center Knowledge published an analysis on May 1, 2026, arguing that the latest round of hyperscaler earnings reports tells a single consistent story: demand for AI computing is growing faster than the infrastructure — data centers, chips, power, and network capacity — available to serve it. According to the piece’s framing, capital expenditure (capex) guidance from the major cloud platforms continues to rise rather than plateau, signaling that the buildout is far from over.

Executive Summary

The analysis, as framed by its headline, synthesizes a quarter of hyperscaler earnings — the results reported by the largest cloud and AI platform operators, a group that conventionally includes Microsoft, Amazon, Alphabet, and Meta — into one thesis: AI demand is outrunning supply, and spending guidance shows no ceiling. “Capex guidance” here means the forward-looking spending plans these companies disclose to investors, most of which now flows into data centers, AI accelerator chips, and the power and land beneath them.

Why it matters: when every major buyer of digital infrastructure reports demand ahead of capacity in the same quarter, the constraint moves downstream. Data center developers, utilities, chipmakers, and network operators become the pacing items for the entire AI economy. That is a materially different market than one where cloud growth is decelerating and operators are digesting capacity — and it shapes pricing, lead times, and investment decisions across the sector.

When the Constraint Is Supply, Not Demand

For most of cloud computing’s history, the operative question was whether demand would materialize to fill the capacity being built. The thesis in this analysis inverts that: hyperscalers are reportedly selling AI capacity faster than they can stand it up. In that regime, revenue growth is gated by how quickly new data centers can be energized — a function of construction schedules, chip deliveries, and above all electrical power — rather than by customer appetite.

That inversion changes behavior across the supply chain. Buyers pre-commit years ahead, developers build speculatively with more confidence, and utilities face interconnection queues measured in years. It also concentrates risk: if capacity is the bottleneck, whoever controls powered land and grid access holds pricing leverage, from wholesale data center landlords down to regional colocation providers.

What ‘No Ceiling’ on Capex Actually Signals

Capex guidance is one of the few forward-looking, board-approved signals hyperscalers publish. Guidance that keeps rising — the piece’s “no ceiling” characterization — implies these companies believe the return on AI infrastructure still exceeds its enormous cost, and that under-building is the bigger risk than over-building. That is a bet on sustained AI monetization: model training, inference services, and AI features embedded across their product lines.

The counterweight, which any even-handed reading should hold onto, is that capex guidance measures conviction, not proof. Spending plans confirm what executives believe about future demand; they do not confirm that end-customer revenue will ultimately justify the outlay. Prior infrastructure cycles — telecom fiber in the late 1990s being the canonical example — show that synchronized, conviction-driven buildouts can overshoot even when the underlying technology trend is real.

Winners, Losers, and the Long Tail

If the thesis holds, the near-term beneficiaries are the picks-and-shovels layer: data center developers and REITs, power equipment manufacturers, cooling vendors, fiber and interconnection providers, and utilities positioned to serve large loads. Enterprises buying AI capacity face the flip side — tighter availability, longer lead times, and less negotiating leverage, which pushes some toward multi-cloud strategies, regional providers, or on-premises deployments where economics allow.

The long tail of the market matters too. When hyperscalers absorb the available supply of chips, transformers, generators, and skilled construction labor, smaller operators compete for what remains. A demand-outrunning-supply cycle at the top of the market tends to propagate scarcity, and therefore pricing power, through every tier beneath it.

Background

Hyperscaler capital spending has been the dominant force in digital infrastructure since generative AI reached mass adoption. Each earnings season, the spending plans of the largest cloud platforms — which fund data center construction, AI accelerator purchases, and power procurement — are scrutinized as a barometer for the whole sector, because these few companies represent an outsized share of global demand for data center capacity, advanced chips, and utility-scale power connections.

Through 2024 and 2025, successive quarters brought upward revisions to those plans, alongside recurring commentary that available capacity, not customer demand, was the limiting factor on AI revenue. The May 2026 analysis discussed here sits in that context: it reads the latest earnings cycle as continued confirmation of a supply-constrained market rather than an inflection toward moderation.
