Qatar Investment Authority & UAE's MGX Join xAI’s $20B Series E Round
The investment comes as xAI exceeded its funding target to scale AI infrastructure and launch new tools.
Artificial intelligence startup xAI, founded by Elon Musk, has raised $20 billion in a Series E funding round, exceeding its original $15 billion target, as global sovereign and institutional investors doubled down on large-scale AI infrastructure.
The round included participation from the Qatar Investment Authority and the UAE-backed MGX, alongside Valor Equity Partners, StepStone Group, Fidelity Management & Research Company, and Baron Capital Group. NVIDIA and Cisco also joined through their investment arms to support the scaling of large GPU clusters.
xAI said the new capital will be used to expand its compute infrastructure, continue training its Grok 5 model, and support the launch of new consumer and enterprise products. The company reported around 600 million monthly users and more than one million GPUs supporting its models across 𝕏, voice-based tools, and multimodal applications.
During 2025, xAI said it scaled its Colossus I and II data centres to more than one million H100-equivalent GPUs, advanced Grok 4 reasoning and agent capabilities using large-scale reinforcement learning, and launched Grok Voice to enable real-time, multilingual interactions across applications and vehicles. The company also expanded Grok’s integration into X for real-time information access and introduced Grok Imagine for image and video generation and editing.
Looking ahead, xAI said it plans to accelerate infrastructure build-out, widen the reach of its products, and deepen research efforts as it continues to develop large-scale AI systems and applications.
