SpaceX Projects $26.5 Trillion AI Market While Grok Struggles to Attract Paying Users

SpaceX has told investors that AI will be the tentpole of its future, describing its rocket launch and satellite businesses as a supporting role. The company acquired Elon Musk’s xAI earlier this year and now operates the Grok models under a new SpaceXAI division. In its S‑1 filing, SpaceX said AI represents most of what it calls the largest actionable total addressable market in history. The filing did not specify the timeframe for the $26.5 trillion estimate, but the figure is close to the US nominal GDP of roughly $32 trillion in the first quarter of 2026.

SpaceX’s internal estimate puts the AI opportunity at $26.5 trillion. An AppMagic survey of 260,000 US AI users found that only 0.174% paid to use Grok in the second quarter of 2026, compared with more than 6% who paid for OpenAI’s ChatGPT. Before the merger, Musk described xAI as the smallest of the AI companies during court hearings for his lawsuit against OpenAI. Third‑party researchers have projected far smaller numbers, with Gartner expecting worldwide AI spending to reach $3.3 trillion by 2027 and Citigroup forecasting a global AI market above $4.2 trillion by 2030.

The huge market figure shows SpaceX’s ambition to capture a slice of AI that rivals the entire US economy, but the low Grok conversion reveals a major hurdle in winning paying customers. Competitors such as OpenAI, Anthropic and Google’s Gemini already enjoy stronger brand recognition and higher payment rates. To close the gap, SpaceX will likely need to improve Grok’s capabilities, adjust pricing, or expand distribution channels, possibly leveraging its integration with the X social platform. Investors will watch whether the company can translate its bold market claim into actual revenue growth.
