Meta is building out many gigawatts of compute.

True: as of mid-September 2026, Meta had announced or was actively building data center or compute capacity adding up to several gigawatts or more (for example multi-GW projects such as Prometheus or Hyperion, or announced plans and contracts totalling well over 2 GW), as shown by Meta announcements, filings or credible reporting. Mostly true: the projects are real and large but the capacity under construction is closer to 1–2 GW, with the rest only planned. Mixed: the gigawatt-scale capacity is mostly announced intentions with little construction under way. Mostly false: Meta's build-out is real but well under a gigawatt, or the projects were largely paused or cancelled. False: there is no gigawatt-scale build-out at all.

   “Meta’s $50 billion-plus, 5 GW Hyperion campus in Richland Parish, Louisiana, is under construction with three Entergy gas plants approved, while a second, seven-plant power buildout heard by state regulators Oct. 7 awaits a Dec. 16 Public Service Commission vote that consumer and environmental groups are contesting.”

   “The company’s internal Meta Compute organization — a top-level division established in 2026 — is planning to build tens of gigawatts of AI infrastructure this decade.”

4. E4 Inside Prometheus: Meta’s Journey to a Gigawatt-Scale Supercluster Meta Engineering (engineering.fb.com) · 19 October 2026 Own record

   “The first phase of Prometheus, our gigawatt-scale supercluster, is already complete and we’re working toward scaling it to comprise ~1 million GPUs.”

In July 2026, Meta announced that it is expanding its Richland Parish, Louisiana data center to 5 GW of compute capacity [E1]. An independent tracker describes this 5 GW Hyperion campus as under construction, with three gas plants already approved [E2]. Independent reporting from July 2026 also covers a 1 GW Alberta data center and Meta Compute plans for tens of gigawatts this decade [E3], and Meta's engineering blog says the first phase of its gigawatt-scale Prometheus supercluster is complete [E4]. Together these show that by mid-September 2026 Meta had announced capacity well over 2 GW, including the 5 GW Richland Parish expansion [E1] and plans for tens of gigawatts this decade [E3]. October reporting describes Hyperion as under construction [E2] and the first phase of Prometheus as complete [E4]. This meets the criteria for true, which accept announced capacity.
