Musk Plans Colossus 2 Chip Doubling as Nvidia Backs Nscale

Elon Musk aims to double the number of Nvidia chips in Colossus 2 by year-end, while iXBT reports that SpaceX will connect another 660,000 Nvidia GB300 GPUs. [1][3] iXBT describes Colossus 2 as the world's largest supercomputer and says its power consumption exceeds 1 GW. [3] Bloomberg's report specifically identifies Nvidia chips as the hardware Musk wants to double in Colossus 2. [1]

Nscale, a two-year-old London-based neocloud led by founder and CEO Josh Payne, filed for a New York listing at a valuation of up to $35 billion. [2] Nscale builds or finances AI-ready data centers and rents out their computing power. [2]

Its filing reported a $1.02 billion net loss for the six months ended June 30, 2026, while its proposed valuation rests on $103 billion in contracts converting into revenue on schedule, although much of that total is not yet firm. [2] Nvidia is Nscale's biggest supplier and an investor, and it committed $1 billion to a $3.1 billion financing round signed September 15 through convertible notes or non-voting shares. [2]

The two developments place Nvidia hardware and financing at the center of distinct AI infrastructure build-outs. Colossus 2 is described through GPU count and power demand, while Nscale is pitching investors on data-center capacity, contracts and future revenue despite a reported loss. The contrast is operational: Musk's plan is an accelerator expansion, whereas Nscale's is a capital-intensive public-market proposition in which its largest supplier is also an investor. What the sources don't address: whether Colossus 2's added GPUs will be connected on schedule or how much of Nscale's not-yet-firm contract pipeline will become revenue.
