Reid Hoffman does not think much of Elon Musk's AI portfolio.
In a public interview published June 24, Hoffman — co-founder of LinkedIn and an early backer of OpenAI — described xAI as a "complete train wreck" and pushed back on any framing of SpaceX as an AI company. The comments land as xAI's Grok competes directly with OpenAI and Anthropic for developer and consumer attention. Hoffman has financial and reputational ties to OpenAI, which puts him squarely in the rival camp.
The remarks matter because Hoffman carries real institutional weight in the AI investment world. When a prominent backer of one lab publicly torches a competitor's credibility, it shapes how limited partners, enterprise buyers, and recruits read the market. Whether the critique is accurate or strategic positioning is a reasonable question to ask.
For context: xAI raised at a valuation that made it one of the most expensive AI startups on paper, and Grok ships inside X to hundreds of millions of users — numbers most labs would not call a train wreck. Hoffman's opinion is informed, but it is also not neutral.
