SpaceX Unveils Memphis Supercompute Cluster: $90B Investment, 2GW of AI Power

On September 26, SpaceX launched a new official website disclosing its AI supercompute infrastructure footprint in the Memphis/Southport (Mid-South) region, listed among the world's most advanced AI training clusters and comparable in scale to top AI companies' datacenters. Shivon Zilis, resharing the news, remarked that even the "mini" facility is absurdly huge.

Confirmed

• The new site discloses over $90 billion in regional investment and roughly 7,500 local jobs, anchored by Colossus and Colossus 2
• Facilities span more than 2.5 million square feet, targeting millions of GPUs with total compute power exceeding 2 GW
• Tesla Megapacks will supply 3.3 GWh to Colossus 2 — enough to power Memphis for two hours — the largest grid-connected battery system in the US
• Blogger @XFreeze adds that the Colossus cluster is expanding into multiple giant facilities, with "Macrohard" infrastructure being built alongside

Why it matters

• 2GW-class compute and millions of GPUs place Musk's ventures in the top tier of the AI compute arms race
• The 3.3 GWh Megapack setup showcases a "datacenter + large-scale battery storage" power model relevant to future hyperscale datacenters
• $90B-scale investment and 7,500 jobs carry significant weight for the Memphis local economy
