State of the AI & Hyperscale Data Center Market — June 2026

June was the month the power question went formal. Federal and Texas regulators both moved to rebuild how large loads connect to the grid — FERC ordered all six organized markets to justify or rewrite their large-load interconnection rules, and Texas approved a batch process for an interconnection queue that now exceeds 438 GW. The demand signal, meanwhile, kept climbing: Oracle closed its fiscal year with $55.7 billion of capital spending and a $638 billion backlog, a 1 GW Stargate campus broke ground in Michigan, and CBRE recorded the tightest vacancy ever measured in the industry's largest market. Halfway through 2026, the buildout is not slowing. It is being re-plumbed.

The regulators arrived

On June 18, FERC issued show-cause orders to all six organized wholesale markets — PJM, MISO, SPP, CAISO, ISO-NE, and NYISO — directing each to justify its existing tariff treatment of large and co-located loads or propose reforms, with responses due within 60 days. The orders reach the questions this industry has been improvising around for two years: how loads above 20 MW get studied, how co-location with generation is treated, and how costs are kept off other customers' bills.

The same day, the Public Utility Commission of Texas approved ERCOT's "Batch Zero" process, which studies large-load requests of 75 MW and above in batches rather than one at a time. The queue it confronts has swelled past 438 GW of requested interconnection — nearly 90% of it data centers — and ERCOT will notify Batch Zero applicants of their classification in August. Neither action slows the buildout; both make it legible. Study processes that force real commitments will separate projects with genuine power from placeholders in a queue, and the published queue numbers should start shrinking toward the truth.

Oracle reset the capex bar

Oracle's June 10 fiscal-year results were the demand datapoint of the month. Fiscal 2026 capital expenditure came in at $55.7 billion — up 162% — with management guiding to $90–95 billion of gross capex in fiscal 2027. Remaining performance obligations reached $638 billion, up 363% year over year, with Bank of America estimating more than half of that backlog traces to OpenAI. Cloud infrastructure revenue grew 93% to $5.8 billion for the quarter, and the company said it expects to energize nearly a gigawatt of computing in the current quarter — roughly what it added in all of fiscal 2026.

The market's reaction was the more interesting signal: shares fell roughly 10% in extended trading, not on demand, but on the financing — plans for tens of billions of dollars in additional debt and equity on top of the roughly $48 billion raised in fiscal 2026. Contracted demand is no longer the question. Funded, powered delivery is, and capital markets have started underwriting the difference.

Ground broke, and vacancy fell

June opened with the groundbreaking of Stargate Michigan in Saline Township: a 1 GW campus developed by Related Digital with Blackstone-arranged funding — roughly $16 billion of development, approaching $56 billion once Oracle's compute is installed. CloudBurst broke ground on a 1.2 GW campus in Central Texas, and Microsoft's roughly 2 GW Pecos, Texas project surfaced with first power targeted for 2028.

Against that supply, CBRE's Global Data Center Trends report, published mid-June, described a market that cannot build fast enough. Northern Virginia vacancy fell to 0.3% — an all-time low for the largest market on earth — even as its inventory grew by 1,135.9 MW year over year, because absorption ran at 1,148.3 MW. Preleasing on new U.S. construction sits in the mid-70% range against a historical norm of 40–50%, and asking rents rose in every region. For first-half context: North American primary markets closed 2025 at a record-low 1.4% vacancy on record absorption of roughly 2,500 MW, and JLL projects the world needs nearly 100 GW of new capacity — about $3 trillion of investment — by 2030.

The pushback is now a market fact

On June 4, the New York legislature passed the Responsible Data Center Development Act, a one-year moratorium on state environmental permits for data centers of 20 MW and above — the first statewide pause to clear a legislature. As of this writing it awaits the Governor's signature. It did not arrive in a vacuum: trackers counted more than 300 data-center bills introduced across statehouses early this year, and local pauses accelerated through the spring in cities from Minneapolis to Baltimore. The skeptics' case sharpened too — June commentary focused on the widening gap between hyperscaler capex growth and AI revenue. These are real signals, and the industry earns its way past them with rate structures that keep data center load off residential bills and siting that communities can live next to — or it doesn't.

Where the market stands at the half

Six months in: demand is contracted before buildings exist, vacancy sits at record lows in every major market, rents are at record highs, and the big five hyperscalers' 2026 capex guidance totals roughly $700 billion. Construction costs keep climbing — JLL puts 2026 global build cost near $11.3 million per MW, with AI-grade fit-out up to $25 million — and grid connection waits exceed four years in primary markets. The binding constraint has not moved in eighteen months: powered, permitted land. What changed in June is that the referees showed up to formalize how that constraint gets allocated.

Where we see it going

First, interconnection reform bifurcates the queue. As FERC-driven tariffs and batch studies force deposits and real commitments, paper positions lose value and utility-confirmed capacity gains it. Expect published queue totals to shrink through 2027 — that is a healthy correction, not a demand signal.

Second, the landlord becomes the underwriting question. With hyperscaler balance sheets stretched and structured capital funding a growing share of delivery, tenants and capital will scrutinize who can actually energize on schedule — not just who controls a site.

Third, the community layer prices in. New York will not be the last state to formalize ratepayer protection and siting review. Projects engineered from day one to fund their own power and stay out of the viewshed will clear faster than projects that treat the host county as an afterthought.

Fourth, no glut in delivered capacity through at least 2027. Mid-70s preleasing and sub-1% vacancy are not the texture of overbuilding, whatever proves true of AI model economics. The risk worth watching is financial — the capex-to-revenue gap — not physical oversupply.

What we're watching in July

RTO responses to FERC's show-cause orders, due by mid-August, with positions forming in July. Whether New York's moratorium is signed. ERCOT's August Batch Zero classifications — the first honest read on the Texas queue. Hyperscaler Q2 earnings and any change to capex guidance. And the pace of data-center securitization against projections of $30–40 billion in annual issuance.
