Artificial intelligence research company xAI officially announced the raise of its Series E round, bringing in $20 billion, well over its target $15 billion for this round. The raise saw participation from investors including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company and NVIDIA. The company is working toward building the world’s largest GPU clusters as it develops advanced AI solutions.

Its new capital will help xAI build out its infrastructure, develop new products and advance its AI research. The company is also currently hiring new talent to its team.
