xAI has announced the completion of its Series C funding round, raising $6 billion. The announcement comes alongside ambitious plans to expand its AI supercomputer infrastructure and accelerate the development of its next-gen AI model, Grok 3.
At the heart of xAI’s strategy lies Colossus, the company’s AI supercomputer that currently houses 100k NVIDIA Hopper GPUs. What’s particularly striking is the speed of deployment – while industry standards typically require 1-2 years, xAI managed to get Colossus running workloads in just 19 days after receiving the first servers.
The company isn’t stopping there. Plans are already in motion to double Colossus’s capacity to 200k NVIDIA Hopper GPUs, implementing NVIDIA’s Spectrum-X Ethernet networking platform to handle the increased computational demands.

xAI’s current flagship model, Grok 2, has established itself with advanced reasoning capabilities, but the company’s ambitions stretch further. The newly secured funding will support the development of Grok 3, which the company positions as its most sophisticated model to date.
The funding announcement reveals xAI’s expanding product portfolio:
- The xAI API offers developers worldwide access to the company’s foundation models
- Aurora, their proprietary image generation model, enhances Grok’s visual capabilities
- Grok on 𝕏 continues to evolve with features like web search and image generation
The $6 billion injection positions xAI to accelerate its research into what it calls “understanding the true nature of the universe.” The company’s rapid infrastructure deployment and ambitious model development suggest we’re watching a significant player emerge in the AI space.
