DayOne Data Centers has filed to sell American Depositary Shares (ADSs) in a proposed US initial public offering, with a Nasdaq listing planned under the ticker DODC. The filing sets out the proposed listing structure, but leaves the number of ADSs and the price range undetermined. The IPO follows the company’s US$4.5 billion Series C financing, which closed in June 2026.

What DayOne’s IPO filing says
DayOne filed a Form F-1 registration statement with the US Securities and Exchange Commission for an IPO of ADSs representing its ordinary shares. It has applied to list the ADSs on the Nasdaq Global Select Market under DODC.

A report said DayOne could seek to raise as much as US$5 billion, but that figure was reported as a potential target—not as an offering amount disclosed in the initial filing.

How the IPO follows DayOne’s Series C
DayOne announced the final closing of a US$4.5 billion Series C on June 5, 2026. The round was led by existing investors Coatue and Hillhouse, with new participation from the Indonesia Investment Authority and Achi Capital Partners.

The company said the financing would support expansion in Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong, Finland and Spain.
14 This gives context to the scale of the business behind the IPO filing, but does not establish how much of the Series C—or any IPO proceeds—will be allocated to each market.
Data center scale in the filing-related figures
Reporting on the filing put DayOne’s customer bookings at about 2.3 gigawatts and its secured resources at 4.6 gigawatts across 10 markets, as of September 20, 2026. These figures describe bookings and secured resources, not the same thing as operating capacity.

What remains unsettled
The F-1 is a registration filing for a proposed offering, not confirmation that the IPO has priced or begun trading. The offering’s ADS count and price range were not yet set in the initial filing, and the reported US$5 billion fundraising figure should not be treated as a finalized deal size.
