What are the latest funding news in the data center market? (June 2026)
Download our beautiful pitch about the data center market
In our data center market deck, you will find everything you need to understand the market
Funding in the data center market stayed highly active in June 2026, with the latest rounds spreading across hyperscale capacity, liquid cooling, power delivery, backup power, and alternative compute locations.
The largest checks went to companies building or operating physical AI-ready capacity, while smaller rounds targeted the power and cooling bottlenecks that now decide how fast new facilities can come online.
This list focuses only on companies tied to space, power, cooling, or facility-level infrastructure, rather than cloud software, GPUs, storage, or networking equipment.
And if you want to better understand this new industry, you can download our pitch covering the data center market.
Insights
- The 12 latest deals represented more than $5.1B in disclosed funding, but over 85% came from just three capacity-heavy rounds: DayOne, Nscale, and Firmus.
- Cooling startups raised at least $168M across ZutaCore, Accelsius, and Nine Labs, showing that thermal infrastructure has become a core data center market investment theme.
