Elon Musk has disclosed the most detailed timeline yet for the expansion of the Colossus 2 AI computing cluster, operated by his company xAI, which has been merged into SpaceX. According to a post on X, the cluster currently houses 110,000 Nvidia GB200 chips and 440,000 GB300 chips. Musk stated that 220,000 GB300 chips will come online next week, with an additional 220,000 expected in November. If conditions are favorable, another 220,000 chips could be deployed by the end of December, potentially more than doubling the current chip count. The business unit previously announced plans to equip the Memphis facility with one million GPUs by 2026. SpaceX completed its acquisition of xAI in February 2026 and has since signed cloud service agreements with Anthropic, Google, and Reflection AI to utilize the Colossus and Colossus 2 data centers.

Elon Musk has announced that the AI computing cluster Colossus 2, built by his company xAI, could more than double its number of Nvidia (NVDA.US) chips by the end of this year. xAI has now been integrated into SpaceX (SPCX.US).
The billionaire provided the most detailed timeline to date for the expansion of the cluster based in Memphis, as he accelerates efforts to scale up computing capacity.
Key Details from Musk's Announcement
In a post on X, Musk stated that Colossus 2 currently operates with:
- 110,000 Nvidia GB200 chips
- 440,000 Nvidia GB300 chips
He further outlined the following deployment schedule:
- Next week: 220,000 GB300 chips to come online
- November: An additional 220,000 GB300 chips expected
- End of December: Potentially another 220,000 chips, "if we get lucky"
Background and Context
The business unit had previously announced plans to equip the Memphis facility with 1 million graphics processing units (GPUs) by 2026.
In February 2026, SpaceX completed its acquisition of xAI in an all-stock transaction. In May, SpaceX signed a cloud services agreement with leading frontier AI company Anthropic, which will utilize computing power from both the Colossus and Colossus 2 data centers. Additionally, SpaceX has entered into computing power cooperation agreements with Google, Reflection AI, and other firms.
