A set of media reports surfaced claiming that xAI, the artificial intelligence company founded by Elon Musk, has raised about $15 billion in fresh capital.

The funding was described as a Series E round that would bring xAI’s total fundraising to roughly $25 billion since September, placing the company among the most heavily funded AI firms in the world.

The valuation tied to the report stood near $200 billion, an extraordinary figure for a two-year-old organisation.

The report circulated quickly across financial news outlets, with several publications citing anonymous sources and unpublished investment documents.

According to those accounts, the funds were earmarked for compute expansion, model training and construction of the company’s planned supercomputing facility known as Colossus.

Musk Rejects The Funding Claims

Elon Musk responded directly on X, calling the report “false”. When Reuters reached out to xAI for confirmation, the company replied with a single automated message stating: “Legacy Media Lies.” The firm has not provided clarification or documentation to counter or confirm the claims.

This contradiction has created a rare situation where one of the world’s most watched technology founders disputes the scale of a funding round reported by multiple outlets. Without an official filing or investor acknowledgement, the size and status of the round remain uncertain.

Why The Claim Matters

The reported figure is notable not only for its size but also because of xAI’s broader ambitions. The company is developing generative AI systems that directly compete with OpenAI, Anthropic and Google DeepMind.

Training such systems requires enormous compute resources, which in turn depend on access to high-end GPUs, custom networking equipment and dedicated data facilities.

If the funding were accurate, it would place xAI in a position to buy tens of thousands of additional compute units and speed up construction of Colossus, a facility that Musk has described as the most powerful computing cluster ever built.

That type of infrastructure underpins the next generation of large-scale models, making capital access a central competitive advantage.

At the same time, investors have been increasingly cautious about valuations in the sector. A $200 billion valuation for a company still in its early stages would draw scrutiny from analysts who are already questioning sustainability in the broader AI funding environment.

What Happens From Here

The next steps depend largely on whether xAI makes the round public through regulatory filings, investor announcements or disclosures from partners involved in the infrastructure rollout.

Any confirmation of GPU procurement, new construction timelines or model-training expansions would signal that the investment, or part of it, did occur.

Until then, the landscape remains ambiguous. Investors, competitors and regulators will continue watching for more evidence. Musk’s denial ensures the story will remain unresolved until documentation appears, making this one of the more unusual funding controversies in the current AI cycle.
