Elon Musk is redirecting dozens of SpaceX's top engineers to build Grok, an AI model designed to compete with the censored, left-leaning machines coming out of Google and OpenAI—and he's backing the play with the full weight of a space empire that just printed $85 billion in its IPO.
This matters because the AI models that increasingly mediate what Americans can say, see, and search online are built by companies with a documented habit of suppressing disfavored viewpoints. OpenAI and Google have both been caught throttling outputs on everything from election integrity to gender biology. If the only AI tools available are trained to lie by omission, free speech doesn't survive the digital age.
Musk wrote on X that "a few dozen" top Starlink and Starship engineers are now dedicating much of their time to overhauling the Grok model. Engineers from Cursor—the AI coding startup SpaceX agreed to acquire for $60 billion this month—are also on the project, with Cursor's training data feeding the new foundation model. Grok 4.5 is currently in private beta at Tesla and SpaceX, and Musk says SpaceX will release new models "trained from scratch" every month this year.
The move doesn't happen in a vacuum. Musk's xAI, founded in 2023 to challenge OpenAI and Google, has lagged behind on coding benchmarks, and the last of its 11 cofounders departed during a sweeping reorganization earlier this year. Musk admitted in March that xAI was "being rebuilt from the foundations up." In February, he merged xAI with SpaceX, combining the AI effort with a company that now has the revenue to fund a serious war.
And what revenue it is. Starlink alone generated approximately $11.4 billion in 2025 revenue and $4.4 billion in operating profit, according to disclosures from SpaceX's IPO process. The satellite internet service has blown past 12 million active customers worldwide across 164 countries. Business Insider framed the engineering shift as SpaceX "playing catch-up in the AI race." Maybe—or maybe a company that just pulled in $4.4 billion in operating profit from Starlink alone is choosing its moment to go on offense.
The Barchart report, meanwhile, buried the AI angle entirely, focusing instead on Starlink's coming direct-to-consumer mobile service and the $17 billion-plus SpaceX spent acquiring EchoStar's wireless spectrum licenses. That's a big story in its own right—Verizon, AT&T, and T-Mobile should be nervous—but it also reveals the infrastructure play underneath the AI push. Musk has said he plans to use the IPO windfall to build up to a million orbital data centers, carried into space by Starship, running on Starlink technology. The same engineers now building Grok are the ones who built the delivery system for it.
Business Insider noted that Grok has trailed OpenAI and Anthropic on coding benchmarks. That's the honest assessment. But the competition's lead is built on models that gatekeep information. If Musk delivers an AI that doesn't, the market shift won't be about benchmark scores—it'll be about who gets to tell the truth.
The open question is whether you can build a free-speech AI inside a company chasing a trillion-dollar telecom convergence without the pressures of scale producing the same compromises that broke the last generation of tech platforms.
