In June 2026, DayOne closed a substantial US$4.5 billion Series C funding round led by Coatue Management and Hillhouse Capital, with new participants including Achi Capital Partners and the Indonesian Investment Authority [1, 2].
Investor interest in data center infrastructure has surged globally amid the rapid growth of artificial intelligence and cloud computing technologies [1, 2].
