According to Reuters sources that declined to be named, DayOne has tapped up new and existing shareholders for the series C fundraising. The global data centre operator, which is affiliated with GDS Holdings, could reportedly be valued at $4-5 billion in the funding round before new capital.

New investors, including global infrastructure funds and sovereign wealth funds in the Middle East, have been approached, according to the sources.

DayOne confirmed the equity fundraising via email last week and said its efforts were independent of GDS. It explained that the company operates under a distinct ownership and governance framework with its own management team, board and investors.

The company was previously known as GDS International and was rebranded as DayOne earlier this year after separating from its parent company. In 2024, the business raised roughly $1.8 billion from two funding rounds, according to GDS. Current investors consist of Hillhouse Investment, Boyu Capital, Coatue Management and the SoftBank Vision Fund, according to company statements.

DayOne has accelerated in the data centre sector this year, already boasting 480MW of data centre capacity in its portfolio of assets that are in service or under construction. It has an additional 590MW reserved for future development across strategic locations in Hong Kong, Singapore, Malaysia, Indonesia and Japan, according to GDS.

In Singapore, the company broke ground on its first data centre in Singapore, a 20MW site designed to support AI and other high-performance workloads. The facility is expected to go live in 2026.

In August, the company announced a $1.4 billion investment into a hyperscale data centre campus in Lahti, Finland – its first entry into Europe.
