Summary

  • Oracle reported delivering 850 megawatts of additional datacenter capacity in Q1 FY2027 (quarter ended August 31, 2026) — almost three times what it delivered in the whole prior quarter and 73% of its total capacity delivery for the previous fiscal year — alongside quarterly capital expenditures of $28.5 billion, up from $8.5 billion a year earlier.
  • The flagship Abilene campus has moved from announcement to delivery: six of its eight buildings, representing 618 megawatts or roughly 75% of campus capacity, were reported delivered to the customer by the Q1 earnings call, with 131,000 GPUs delivered there in the quarter.
  • The disputed 600-megawatt Abilene expansion was never a finalized lease; it was dropped in March 2026, while Oracle separately stated that leasing for the much larger 4.5-gigawatt OpenAI program had been completed — a distinction that resolves much of the March dispute on the record.
  • Concentration remains the load-bearing risk: the partnership with OpenAI, reported at more than $300 billion over roughly five years, links Oracle's delivery pace to a single counterparty's demand and financing health, which is now visible in credit-market scrutiny of Oracle's debt.

850 megawatts, and what it cost

The most concrete number in Oracle's fiscal first quarter of 2027 is a rate. The company's September 10, 2026 press release stated that total quarterly revenues increased 30% to $19.3 billion, "reflecting strong execution in our infrastructure business, with the delivery of 850MW additional datacenter capacity." https://www.prnewswire.com/news-releases/oracle-announces-q1-results-driven-by-triple-digit-growth-in-cloud-infrastructure-revenues-302875728.html The same release put IaaS revenue at $7.4 billion, up 121%, and remaining performance obligations at $664 billion, a $209 billion increase year-over-year. It also disclosed that Oracle booked more than $30 billion of additional AI cloud contracts in the quarter, structured, the company said, so as to require no incremental capital raise, and that more than 300,000 GPUs had been delivered to AI Cloud customers since the end of the prior quarter — nearly triple the Q4 FY26 volume. https://www.prnewswire.com/news-releases/oracle-announces-q1-results-driven-by-triple-digit-growth-in-cloud-infrastructure-revenues-302875728.html

The rate matters more than the level. On the earnings call, management characterized the quarter's 850 megawatts as almost three times the capacity delivered in all of Q4 FY26 and equal to 73% of the total capacity delivered across the entire prior fiscal year. https://www.fool.com/earnings/call-transcripts/2026/09/11/oracle-orcl-q1-2027-earnings-call-transcript/ In other words, a single quarter now delivers roughly three-quarters of what took Oracle a full year to build and hand over only two quarters ago. That is the single clearest quantitative evidence that the company's buildout has shifted from planning to execution at scale.

The capital behind that execution is equally concrete. CNBC reported Oracle's Q1 FY27 capital expenditures at $28.50 billion, up from $8.50 billion a year earlier. https://www.cnbc.com/2026/09/10/oracle-orcl-q1-earnings-report-2027.html Dividing capex by delivered megawatts yields a rough unit cost of about $33 million per megawatt for the quarter — not a precise construction accounting, but a useful order-of-magnitude check that the spending and the delivery claims describe the same program rather than two different ones.

Abilene: from site to delivered capacity

The flagship of the Oracle-OpenAI buildout is the Abilene, Texas campus developed by Crusoe. The earnings-call transcript is the most specific public source on what has actually been handed over: six of the eight campus buildings, representing 618 megawatts and about 75% of total campus capacity, "have now been delivered to the customer." https://stockanalysis.com/stocks/orcl/transcripts/689425-q1-2027/ Management also stated that 131,000 GPUs were delivered at Abilene in the quarter — 1.9 times the Q4 volume — and that the recently released GPT-6 Astra model was trained at the Abilene site. https://stockanalysis.com/stocks/orcl/transcripts/689425-q1-2027/

That last claim is worth pausing on. OpenAI's own posts have attributed earlier flagship training — GPT-5.5 — to Abilene operating on Oracle Cloud Infrastructure with NVIDIA GB200 systems. https://openai.com/index/building-the-compute-infrastructure-for-the-intelligence-age/ The two statements do not contradict each other so much as mark successive checkpoints: training successive model generations at the same campus is precisely what a delivered, customer-accepted capacity ledger looks like in practice. But the attributions come from different parties at different times, and neither constitutes an independent audit of where which model was trained.

OpenAI's July 2025 announcement records the origin of the program: an agreement to develop up to 4.5 gigawatts of additional Stargate capacity in the United States, with Oracle having begun delivering the first NVIDIA GB200 racks to Abilene in June 2025. https://openai.com/index/stargate-advances-with-partnership-with-oracle/ OpenAI's September 2025 five-site announcement extended the picture, stating the partnership exceeds $300 billion over roughly five years and naming three new Oracle-developed sites — Shackelford County, Texas; Doña Ana County, New Mexico; and a Midwest site — plus a potential 600-megawatt Abilene expansion, together over 5.5 gigawatts of planned capacity. https://openai.com/index/five-new-stargate-sites/

The 600-megawatt question, resolved and unresolved

In March 2026, Reuters — attributing Bloomberg News and unnamed sources — reported that Oracle and OpenAI had dropped plans to expand the flagship Abilene data center, a potential 600-megawatt expansion that would have pushed the campus from roughly 1.2 gigawatts toward 2 gigawatts, after negotiations over financing and OpenAI's changing needs dragged on. The report said the 600 megawatts would instead be fulfilled at one of the other campuses being built. https://www.reuters.com/business/oracle-openai-end-plans-expand-texas-data-center-site-bloomberg-news-reports-2026-03-06/

Oracle's response was emphatic but selective. In public posts the company called reports of problems at Abilene "false and incorrect," said it and developer Crusoe were "operating in lockstep" to deliver one of the world's largest AI data centers, confirmed two buildings fully operational, and stated that leasing for the additional 4.5 gigawatts "to deliver on our commitments to OpenAI" had been completed. https://finance.yahoo.com/news/oracle-hits-back-stargate-data-172802489.html What Oracle's rebuttal did not do was directly address whether the Abilene expansion lease specifically had been dropped — a gap that Bloomberg's Ed Ludlow effectively filled with a correction, stating that Oracle and OpenAI "are not moving ahead with the planned expansion lease" while the separate 4.5-gigawatt agreement "remains on track." https://finance.yahoo.com/news/oracle-hits-back-stargate-data-172802489.html

The most useful reconciliation on the record comes from technical and regional press: the existing eight-building Abilene campus is unaffected; what collapsed was a separate, never-finalized expansion lease that would have pushed the site toward 2 gigawatts. https://www.tomshardware.com/tech-industry/oracle-and-openai-scrap-planned-600mw-abilene-expansion The Houston Chronicle added texture to why: relations between Oracle and Crusoe had been strained by reliability issues, with data center buildings offline for days earlier in the year due to winter weather affecting liquid cooling machinery, even as both companies said the relationship remained strong. https://www.chron.com/business/technology/article/oracle-openai-end-plans-to-expand-flagship-data-21960804.php The Chronicle also reported that Meta was evaluating the space originally earmarked for OpenAI, with NVIDIA facilitating discussions. https://www.chron.com/business/technology/article/oracle-openai-end-plans-to-expand-flagship-data-21960804.php

Read together, the record supports a precise distinction that the March headlines blurred: a dropped expansion option at one site coexists with a contracted, larger multi-site program whose leasing Oracle says is complete. Neither fact vouches for the other. "Leasing completed" for 4.5 gigawatts means leases are signed; it does not mean buildings are energized or that customers have accepted capacity. The Q1 delivery figures — 850 megawatts company-wide, 618 megawatts at Abilene — are the only public evidence of what has actually converted.

What is not yet delivered

Between the announcement ledger and the delivery ledger sits everything still in motion. OpenAI's own aggregate claims — that it surpassed its 10-gigawatt U.S. commitment ahead of the 2029 target, with more than 3 gigawatts added in a recent 90-day window — are partner-side planning statements about OpenAI's total footprint, not Oracle-specific commissioned-capacity disclosures. https://openai.com/index/building-the-compute-infrastructure-for-the-intelligence-age/ The three new sites named in September 2025 remain, in public record, announced projects rather than verified operational capacity. https://openai.com/index/five-new-stargate-sites/

The financial structure compounds the asymmetry. The Wall Street Journal reported — via anonymous sources, without company confirmation on the record — that OpenAI signed a contract to purchase about $300 billion in computing power from Oracle over roughly five years. https://www.wsj.com/business/openai-oracle-sign-300-billion-computing-deal-among-biggest-in-history-ff27c8fe Oracle's own disclosures reinforce the concentration: RPO of $664 billion against $7.4 billion of quarterly IaaS revenue, with the majority of the newly booked contract value attributed in press reporting to a single customer. https://www.prnewswire.com/news-releases/oracle-announces-q1-results-driven-by-triple-digit-growth-in-cloud-infrastructure-revenues-302875728.html Secondary analyses in 2026 have documented rising credit-spread scrutiny of Oracle's debt tied to exactly this OpenAI contract concentration. https://nexfinitynews.com/oracle-debt-and-openai-contracts-what-rising-cds-spreads-signal-in-2026/

The delivery ledger, in short, shows real execution at unprecedented speed: 850 megawatts delivered in one quarter, a flagship campus three-quarters handed over, successive model generations trained on the delivered capacity. It also shows a company whose announced pipeline — 4.5 gigawatts leased, 5.5 gigawatts named, $300 billion contracted — remains several times larger than its delivered base, and whose conversion of that pipeline now depends on a single counterparty's demand curve holding for half a decade.
