The data centers powering your favorite AI chatbot are running low on helium, cash, and neighbors who don’t hate them, and that’s not even the worst of it.

According to reporting by Bloomberg, about half of the data centers slated to open in the US in 2026 will either face delays or outright cancellations.

The publication interviewed analysts at market intelligence company Sightline Climate, which in research first flagged by Ed Zitron last week noted that 12 gigawatts worth of power-consuming data centers are set to open in the US this year. But here’s the catch: they say only a third of those are actually under construction right now, with the rest in a liminal pre-production stage in which they could, and likely will be, canceled.

It’s not just a problem for data centers planned for 2026, either. Among data centers slated to open in 2027, only about 6.3 gigawatts worth of computing infrastructure are actually under construction, compared to 21.5 announced gigawatts.
