# DayOne's $4.5B Series C: Asia's Data-Center Buildout Hits Mega-Scale

> Singapore's DayOne closed a $4.5B Series C in June 2026, led by Coatue and Hillhouse, to expand AI data centers across Singapore, Malaysia, and Indonesia.

DayOne's **$4.5B Series C** in June 2026 is the largest Asian venture deal of the period — and a vivid sign that **the AI economy runs on data centers.** The Singapore operator now anchors Southeast Asia's AI-infrastructure buildout.

### The problem this startup is attacking
AI demand is outstripping data-center capacity across Asia-Pacific. DayOne builds and operates the large-scale facilities — and secures the power — that AI workloads require.

### Why this is a live problem now
- AI compute demand is exploding regionally.
- Power and land for hyperscale capacity are scarce.
- Governments want sovereign, in-region data infrastructure.

### Competitive map
- Regional and global hyperscale data-center operators.
- Cloud providers building captive capacity.
- Telco and sovereign-fund-backed infrastructure plays.

### Market signal (the number to remember)
- **$4.5B final close, 1.5GW+ booked capacity** — Coatue and Hillhouse (now DayOne's two largest shareholders) plus the Indonesia Investment Authority signal sovereign-grade conviction. A Singapore/US dual listing is reportedly under consideration.

### Practical takeaway (operator + investor)
DayOne shows the **infrastructure layer of AI** commands the biggest checks in Asia. Founders in adjacent categories should anchor to contracted capacity and power access; investors should treat data centers as a core AI-era allocation.
