‘SpaceX Will Be Worth More Than Earth’: Elon Musk Reveals Bold 1 Petawatt Power Goal for the Moon

Space Exploration Technologies Corp. (NASDAQ:SPCX) CEO Elon Musk reiterated his goal of reaching 1 Petawatt of power annually on Wednesday as the commercial spaceflight giant targets the Moon and Mars.

Elon Musk Touts 1 Petawatt/Year on the Moon

In a post on the social media platform X, user vittorio quoted Musk’s post about SpaceX sourcing solar manufacturing equipment for the Starmind AI compute satellite constellation, which the billionaire had said would help create a “sentient sun.” The user said that the move could help SpaceX generate a fifth of the U.S.’s annual power needs.

“Actually, we’re aiming for 1TW/year from Earth, rising to over 1PW/year from the Moon,” the billionaire said in his response to the user. “That’s why I say that if we achieve this outcome, SpaceX will obviously be worth more than Earth, because space is so staggeringly enormous!” he added.

That’s why I say that if we achieve this outcome, SpaceX will obviously be worth more than Earth, because space is so staggeringly enormous!

As stated above, this is not the first time Musk has targeted reaching a petawatt of power. However, the petawatt goal could be a part of the billionaire’s target of making humanity reach a Kardashev II civilization that will be capable of harnessing all of the Sun’s power. For reference, a petawatt is equal to 1,000 Terawatts (TW) or a million gigawatts (GW).

Elon Musk’s $10 Trillion Remark

On Tuesday, the billionaire made a bold claim that he could reach a net worth of $10 trillion sometime in the future after he had successfully reached trillionaire status earlier this year following SpaceX’s IPO in June. Musk has said that most of his wealth is tied to his stake in Tesla Inc. (NASDAQ:TSLA) and SpaceX.

In July, the SpaceX CEO had predicted that SpaceX could become more valuable than the entire planet if the company was successful in achieving its goals.

SpaceX’s ‘Actually Usable’ Compute

In a separate post on Wednesday, the billionaire also responded to user zerohedge, who shared a chart showcasing the credibility of compute buildouts touted by companies like Meta Platforms Inc. (NASDAQ:META), Alphabet Inc. (NASDAQ:GOOGL) (NASDAQ:GOOG), Amazon.com Inc. (NASDAQ:AMZN) and more.

“SpaceX has a chance of going about half the GW next year of actually usable compute,” Musk said in his response. He added that “actually usable” was an “important metric.”

Musk also said that SpaceX took roughly two months to get a compute cluster to work “reliably” after “working 24/7.” He added that rivals took close to six months to accomplish the same goal.

SpaceX has a chance of going about half the GW next year of actually usable compute.

"Actually usable" is an important metric. It takes us ~2 months working 24/7 to get a large compute cluster working reliably. I’d guess closer to 6 months for others.
