Investors participating in the round include Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX and Baron Capital Group, amongst other key partners. Strategic investors in the round include NVIDIA and Cisco Investments, who continue to support xAI in rapidly scaling our compute infrastructure and buildout of the largest GPU clusters in the world.

Not officially confirmed by xAI, but widely reported in the $230 billion+ range based on pre-round discussions and the upsized nature of the funding.

2025 xAI team key achievements including:

Data Centers: xAI continues to expand its decisive compute advantage with the world’s largest AI supercomputers at Colossus I and II, ending the year with over one million H100 GPU equivalents.

Grok 4 Series: our frontier language models are built on the best-in-class training infrastructure powered by Colossus. xAI has pushed reinforcement learning training to unprecedented levels, refining Grok’s intelligence, reasoning, and agency using pretraining-scale compute.

Grok Voice: the most intelligent voice agent driving real-time conversations in voice mode and available via agent API. Grok Voice delivers low-latency speech in dozens of languages, tool calling, and real-time data access, serving millions of users across the Grok mobile app and in Tesla vehicles.

User metrics: our reach spans approximately 600 million monthly active users across the 𝕏 and Grok apps.

Grok Imagine: our lightning-fast image and video generation models that brings state-of-the-art multimodal understanding, editing, and generation capabilities.

Grok on 𝕏: leveraging the 𝕏 platform to understand what’s happening in the world in real-time, utilizing xAI’s most powerful model to date.

Grok 5 is currently in training, and xai is focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play.

  2. I don’t know how he does it, but Elon seems to be a step ahead of everyone else. He sees where the future is heading and then acts decisively. Right now, it’s data centers in space, and using Twitter/X as training data for Grok AI.

    It’s become the most obvious of questions: How did he know that Integrating batteries, transportation, reusable rockets, satellite internet, Neurolink, tunnel-building, and AI – all to get humans to Mars – would be doable, and that it would make him the wealthiest man in history? Either he’s the luckiest man alive, or he’s a modern Nostradamus.

    Amazing.
