In his pursuit to create “AI superintelligence,” Meta’s CEO Mark Zuckerberg is teasing plans to build not one, but several energy-hungry data centers dedicated to AI training. 

Back in January, Zuckerberg mentioned creating a data center so large it would cover large parts of Manhattan island if placed in New York City. On Monday, he indicated Facebook’s parent company Meta has been expanding on those plans by investing “hundreds of billions of dollars into compute to build superintelligence.”

The resulting data centers will not only feature hundreds of thousands of AI-focused GPUs, but also require over 1,000 megawatts of electricity, or what amounts to a gigawatt. 

“We're actually building several multi-GW (gigawatt) clusters,” Zuckerberg wrote in a Facebook post. “We're calling the first one Prometheus and it's coming online in '26. We're also building Hyperion, which will be able to scale up to 5GW over several years.”

But Zuckerberg isn’t just settling for two mega data centers. In the same post, he wrote: “We're building multiple more titan clusters as well. Just one of these covers a significant part of the footprint of Manhattan.” 

For perspective, the world’s leading supercomputer, El Capitan, uses only 30 megawatts, or about three times the amount of power used in the neighboring city of Livermore, California.  Meanwhile, Elon Musk’s xAI “Colossus” data center in Memphis has been estimated to use 150 megawatts, although that’s bound to grow as the facility expands. 

Zuckerberg’s post is the latest sign of how aggressively the largest tech companies are racing to build AI that promises to surpass human intelligence. In addition to the data center push, Meta has been offering huge compensation packages, at up to over $100 million, to poach the top AI researchers from companies including OpenAI and Apple. 

Meta's investment will raise questions about whether the bet pays off and if it takes an environmental toll. Zuckerberg didn’t mention how Meta plans on powering these upcoming mega data centers. But according to the research firm SemiAnalysis, the company is preparing to build natural gas plants to power the Prometheus data center, which is being built in Ohio.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
