Grok falters, SpaceX leases compute

DigiTimes reported on May 25 that xAI’s Grok has struggled to gain traction across U.S. government, corporate and consumer markets, and that SpaceX responded by leasing idle compute capacity to Anthropic. The report said Grok underused infrastructure that had been built out for Elon Musk’s AI push, leading SpaceX to reallocate capacity rather than leave hardware sitting idle. Separate reports in the past week, including Reuters and The Wall Street Journal, described weak U.S. federal adoption of Grok and a large Anthropic compute deal tied to SpaceX’s data-center footprint. ### How does the DigiTimes report fit with what others have already found? Reuters reported on May 21 that Grok had been a poor seller with the U.S. government, one of the biggest enterprise AI buyers. Its report said Grok showed up in only three of more than 400 federal AI use cases it reviewed, far behind OpenAI’s 234. Reuters said the finding undercut part of the growth story around SpaceX’s IPO and its artificial-intelligence ambitions through xAI. (digitimes.com) DigiTimes extended that picture beyond Washington. Its May 25 item said the weak uptake was not limited to government accounts but also showed up in corporate and consumer markets, and that the consequence was underused infrastructure inside the broader Musk ecosystem. The report, as surfaced in search results and aggregation pages, said SpaceX pivoted to leasing that compute to Anthropic. ### What exactly is SpaceX leasing to Anthropic? (usnews.com) The Wall Street Journal reported that Anthropic is renting compute capacity across SpaceX’s two large data centers for about $1.25 billion a month. The Journal said the agreement runs through May 2029, with capacity ramping in May and June at a reduced fee. Business Insider and Data Center Dynamics separately cited SpaceX IPO disclosures describing the same arrangement. (digitimes.com) Data Center Dynamics reported that SpaceX’s IPO filing said Anthropic would pay $1.25 billion a month over three years to rent space at xAI data centers. That framing matters because it suggests the infrastructure being leased was substantial enough to become a disclosed revenue line in offering materials, not a small overflow arrangement. (wsj.com) ### Why would a rival AI company rent Musk-linked capacity? Anthropic’s side of the deal appears to reflect demand for large-scale compute rather than any shift in product alignment. The Journal and Business Insider both described the agreement as a way for Anthropic to secure scarce data-center capacity for AI growth, while SpaceX monetized hardware that was not fully occupied by Grok demand. (datacenterdynamics.com) Ars Technica, citing the same broad set of IPO-era disclosures and reporting, wrote that SpaceX was pitching AI as a major future business even as customers often preferred models from OpenAI and Anthropic. That account lines up with the DigiTimes description of a mismatch between infrastructure buildout and customer adoption. (wsj.com) ### What does this say about Grok’s position in the market? xAI has continued to launch products around Grok, including coding and voice offerings cited in recent coverage, but the available reporting points to a gap between product velocity and signed demand. Reuters’ federal-use-case tally is the clearest independently reported evidence of that gap in one major customer segment. DigiTimes said the weakness also extended to enterprise and consumer markets, though that broader claim has been less fully detailed in public summaries than the federal numbers. (arstechnica.com) The next documents to watch are SpaceX’s IPO filings and any additional disclosures around the Anthropic contract, data-center utilization and xAI revenue. Reuters tied Grok’s federal adoption problem to SpaceX’s offering story on May 21, and the Journal said the Anthropic lease runs through May 2029 with ramp-up beginning in May and June 2026.
