Musk says AI could expand the global economy by 20% to 30%

By Daniel Okafor

Elon Musk said AI could expand the global economy by 20% to 30% and double white-collar productivity.

The Tesla and SpaceX CEO, whom Business Insider identifies as the world's richest man, spoke by webcast at Baron Capital's annual conference on Friday. Musk said: “Super intelligence will saturate all human needs by far.”

What does Musk's castle scenario mean?

Musk said: “You could wish for a castle, or whatever you want basically, and the digital superintelligence can make it for you as a side project.”

His thesis links cheaper energy, AI and robotics to much higher output. Musk has repeatedly said these advances will slash costs, supercharge productivity and boost growth. He expects goods and services to lose scarcity while money loses much of its force.

On April 18, 2026, Musk wrote on X: “Actually, AI/Robotics will mean everyone can have a penthouse if they want.”

He added: “The output of goods & services will be several orders of magnitude higher than today’s economy.” Musk also wrote: “Read the Iain Banks Culture books for the best imagining of how it will be.” He concluded: “Amazing abundance seems the best to me.”

Musk told Ron Baron, one of his biggest shareholders and a steadfast supporter, that progress could harness enough energy to “completely saturate anything anyone could ever wish for on Earth.” He said: “Our economy will seem quaint, and our money system will seem like exchanging seashells for currency.”

How do robots turn that forecast into output?

Musk's forecast rests on four linked numbers:

• 20% to 30% expansion in the global economy from digital superintelligence.
• 2x productivity in white-collar work.
• 5x productivity for humanoid robots compared with people.
• 20 million to 30 million robots matching the current output of working Americans.

Musk said robots would work faster and “be on the job 24/7.” He said they do not “take vacation, or bathroom breaks, or need to eat food, or anything like that.”

His scale estimate was equally aggressive. Twenty million to 30 million robots could match the current output of working Americans, Musk said. In his account, that robot labor supplies output while digital superintelligence raises white-collar productivity.

Musk paired the forecast with two social promises: “universal extremely high income” and “universal medical care that is better than the best medical care available on Earth today.” Those claims extend his productivity forecast into household income and medical access.

Can data centers deliver growth without a backlash?

Musk addressed public backlash against AI data centers over water use, power consumption and noise. He used Memphis, Tennessee, as his counterexample, saying SpaceX’s presence had made the city “booming.”

“The restaurants are full, the hotels are full. We’re paying at times twice the prevailing wage that people were earning before,” Musk said. “We’ve also helped out with local schools, and the tax revenue that the county and the city are earning is tremendous.”

Musk presented data-center expansion as a local economic engine. His Memphis example links fuller restaurants and hotels, higher wages, and county and city tax revenue to SpaceX's presence. The claim answers the infrastructure objections directly. Musk pairs SpaceX-linked benefits with the data centers' power, water and noise costs.

What could break the path to abundance?

Musk has faced intense skepticism over earlier claims that people should stop saving for retirement because wealth will become “irrelevant.” He has also proposed universal government checks as the best response to AI-driven job losses.

Bill Gates, Microsoft’s cofounder, recently made a related forecast. He said AI will usher in “true abundance,” while robots will “build houses, grow food, do surgery.” Gates warned that the 20-year transition will be hugely “tumultuous” because people will no longer be needed to make most goods and services.

Anthropic CEO Dario Amodei offered a more qualified version. He said AI promises to “raise the quality of life for everyone,” but there will be “unprecedented” disruption before it does.

The near-term business test is not whether AI can build a castle. It is whether AI, cheaper energy and robotic labor can scale together as job losses and data-center backlash complicate the transition. Gates’s 20-year warning and Amodei’s disruption forecast make that adjustment period the more immediate economic risk.
