Memphis, USA — November 14, 2025:
Elon Musk on Thursday forcefully denied a CNBC report claiming that his artificial intelligence startup, xAI, had raised $15 billion in a Series E funding round. The report alleged that the new capital expanded a previously reported $10 billion raise, valuing the company at $200 billion—figures Musk dismissed as “false,” continuing a months-long dispute over how xAI’s financing is being portrayed in the press.
CNBC had earlier reported that xAI was pursuing a $10 billion raise, a story Musk also rejected at the time. In response to a Reuters inquiry about the latest claims, xAI issued what appeared to be an automated message: “Legacy Media Lies.” The blunt reply reflects rising hostility between the startup and major media outlets, as xAI positions itself not just as a competitor in the AI sector but also as an outspoken critic of institutional reporting.
Despite Musk’s denial, the renewed speculation points to persistent questions around how aggressively investors are backing xAI. The startup, founded in July 2023, has become one of the fastest-growing challengers to OpenAI and Anthropic, rapidly expanding its technical infrastructure to support next-generation model training. Much of the funding xAI is believed to be seeking—regardless of whether recent figures are accurate—would go toward purchasing advanced GPUs, the backbone hardware required to train large language models at scale.
Investor enthusiasm for artificial intelligence firms remains intense even as analysts warn of overheated valuations and unsustainable spending across the industry. AI infrastructure requires enormous capital; securing cutting-edge GPUs has become a competitive bottleneck, driving companies to pour billions into data centers, energy systems and specialized chips. Musk has repeatedly argued that xAI needs significant resources to catch up with competitors who have benefitted from years of head starts and early capital.
Beyond hardware, xAI is investing heavily in physical expansion. The company has been acquiring property in Memphis, Tennessee, where it plans to build the Colossus supercomputer. Musk has described Colossus as one of the most powerful AI systems in the world—an ambitious claim that underscores xAI’s intention to become a dominant force in advanced model training. Local development filings, equipment orders and early construction activity indicate xAI is moving quickly to build the kind of infrastructure typically associated with national research labs or big-tech hyperscalers.
The dispute over funding disclosures highlights broader tensions surrounding Musk’s approach to communication and transparency. While other AI firms willingly publicize fundraising totals and valuation milestones, xAI’s strategy has been to reject or mock reporting from legacy media, leaving investors and industry observers to parse conflicting signals. Musk’s outright dismissal of the alleged $15 billion round suggests either that negotiations remain private or that the company is aiming to control its narrative as it scales at breakneck speed.
As the AI arms race accelerates, the pressure to secure compute power, talent and capital has never been higher. Whether or not xAI has raised the sums claimed in recent reports, the company’s infrastructure push—from GPU procurement to the Colossus supercomputer—signals its intent to compete at the highest levels of the global AI industry. The question now is how much runway Musk can secure, and whether xAI’s rapid expansion will match the pace—and the spending—of its far more established rivals.
