DayOne Data Center IPO Filing Shows 2.3 GW in Bookings

DayOne Data Centers’ October 5, 2026 Form F-1 puts a clear number behind the AI infrastructure race: about 2.3 gigawatts of contracted capacity, with an estimated US$11.4 billion still required to complete those bookings. The Singapore-based operator’s proposed Nasdaq listing is an unusually direct look at the gap between signed demand and the capital needed to build it.

The filing, submitted to the US Securities and Exchange Commission on October 5, is a preliminary registration statement, not a priced deal. DayOne says it applied to list American depositary shares on Nasdaq under the symbol DODC, but the number of shares and expected price range remain blank. The company cannot sell the securities before the registration statement becomes effective. Those omissions matter: investors have operating data, but not the terms required to value the proposed offer.

DayOne describes an infrastructure model built around power, land and long-term customer contracts. Its filing says bookings, defined as capacity committed under legally binding contracts, were approximately 2.3 GW as of September 20, 2026. The company expects substantially all of that capacity to be delivered by December 31, 2028, based on current estimates. Bookings are not the same as operating capacity or recognized revenue. Construction schedules, customer installation and power availability still sit between a contract and cash generation.

The buildout is capital intensive. DayOne estimates approximately US$11.4 billion to complete its bookings, after spending through June 30, 2026, net of costs incurred through June 30, 2026. It says current capital resources should be sufficient to fund the existing bookings, but the F-1 also flags execution, financing and power risks. That estimate is a company projection, not a fixed-price commitment. Cost overruns, delays or changes in customer demand could change the amount and timing of required capital.

Revenue is growing quickly alongside the buildout. The filing reports US$512.0 million in revenue for the six months ended June 30, 2026, compared with US$151.5 million in the six months ended June 30, 2025, a 238.0% increase. DayOne attributed the growth to capacity deliveries in Johor, Batam and Thailand. Its billings measure rose from 213 megawatts at June 30, 2025 to 666 megawatts at June 30, 2026. These figures show deployment progress, but do not by themselves establish the returns on the capital being invested.

Costs also climbed. For the first half of 2026, cost of revenue rose 249.5% from the six months ended June 30, 2025 to the six months ended June 30, 2026, reaching US$375.6 million, faster than the increase in revenue. The company compared costs with the six months ended June 30, 2025, and cited higher power costs from greater customer consumption and higher depreciation as capacity in service expanded. Power costs are generally passed through to customers according to actual consumption, but the filing says DayOne typically commits to minimum power purchases. If customer usage falls short of those commitments, the operator may have to absorb costs. That leaves utilization and delivery milestones central to the margin story.

Customer concentration is the most immediate business risk disclosed. DayOne’s largest customer, described in the F-1 as a global technology company operating a leading short-form video platform, accounted for 69.2% of revenue in the six months ended June 30, 2026, compared with 69.4% in the year ended December 31, 2025. The second-largest customer contributed 15.1% in the six months ended June 30, 2026, compared with 12.3% in the year ended December 31, 2025. DayOne says it serves seven global hyperscale and leading technology customers across its bookings. The breadth of the contract book is therefore much narrower than the total customer count might suggest: one tenant represents most current sales.

Geographic concentration adds another exposure. Malaysia accounted for 87.0% of DayOne’s revenue in the six months ended June 30, 2026, up from 81.5% in the year ended December 31, 2025, according to the filing. The company says its Southeast Asian strategy links Johor, Batam and Singapore, with further projects planned in other markets. Regional power approvals, construction execution and local infrastructure will determine how readily that footprint can expand. The filing’s proposed offering does not yet provide a price at which investors can weigh those risks against the growth.

The bullish case is that contracted demand and rising billings can translate into a larger operating base before the expected 2028 delivery window closes. The countercase is that the same expansion requires heavy spending while revenue depends on a concentrated set of customers and power arrangements. The filing provides evidence for both: rapid first-half growth and a sizeable cost-to-complete estimate, plus an explicit warning that the company may not diversify its customer base successfully.

The next useful evidence is not a headline valuation from an unofficial source, but the next amended F-1. It should disclose the offering size, price range, share count and updated financial information. Until those terms are filed and the registration statement becomes effective, DayOne is a proposed listing with a reported operating footprint, not a completed IPO.
