Elon Musk stated on Sunday that becoming a quadrillionaire is 'not impossible,' but suggested such a milestone would require the establishment of factories on the Moon and Mars. The Tesla and SpaceX CEO indicated that a future economy supporting this level of wealth would likely move away from dollars, relying instead on mass and energy as currency. The remarks followed a historic initial public offering (IPO) for SpaceX that significantly altered Musk's financial standing.

Musk responded to a post on X highlighting that he would need an additional $998.9 trillion to reach the quadrillionaire mark. 'Not impossible, but definitely requires factories on the Moon and Mars to achieve,' Musk wrote. 'By then, I don't think dollars will be used as currency. Just mass and energy.' This perspective aligns with his previous statements regarding the potential value of his SpaceX equity package and the long-term trajectory of human civilization.

SpaceX executed its IPO on the Nasdaq under the ticker SPCX on Friday, selling 555.6 million shares at $135 each. The offering raised $75 billion, marking the largest IPO on record. The stock opened at $150, peaked at $176.52, and closed its first session at $160.95, representing a 19% gain. This debut valued SpaceX at more than $2.1 trillion, positioning it as the sixth-most valuable public company in the United States.

Forbes estimated that the IPO pushed Musk's net worth to approximately $1.1 trillion, making him the world's first trillionaire. Earlier on Sunday, Musk also forecasted that SpaceX could achieve roughly $1 trillion in revenue by 2030. His vision includes the development of a 'Moon City' and off-Earth infrastructure for artificial intelligence and manufacturing, though these targets remain speculative and dependent on technologies like Starship's full reusability.

Space Exploration Technologies Corp. began trading on the Nasdaq at $150 per share, giving the company a nearly $2 trillion market cap and making CEO Elon Musk the world's first trillionaire. The IPO boosted Musk's fortune to an estimated $1.1 trillion as of Friday morning, with his net worth rising by $188 billion to an estimated $982 billion on Thursday evening when SpaceX priced the IPO at $135 per share. By midday Friday, shares rallied to $175, a gain of about 30% from the listing price, as the company debuted as the world's biggest IPO ever. The offering generated roughly $75 billion in gross proceeds from 555.6 million shares of Class A common stock, with demand topping $250 billion.

Market Reaction And Sector Rotation

The record listing prompted a sharp rotation in the space complex, as investors moved capital toward the new heavyweight. AST SpaceMobile Inc. plunged 14.6%, while Rocket Lab Corporation tumbled 10.1%. Smaller players faced steeper declines, with Firefly Aerospace Inc. sinking 17%, Velo3D Inc. falling 16%, and EchoStar Corporation dropping 15%. Exchange-traded funds tracking space stocks also sold off; the Global X Space Tech ETF fell nearly 8%, the VanEck Space ETF dropped 6.8%, and the Tema Space Innovators ETF lost 6.5%.

Financial Metrics And Valuation

Despite a $4.9 billion loss in 2025, investor appetite remains strong. Based on 2025 revenue of $18.7 billion, investors are paying nearly $80.2 for every dollar of revenue, a price-to-sales multiple exceeding that of NVIDIA Corp, Broadcom Inc, and all members of the Magnificent Seven. SpaceX's valuation exceeds the combined market capitalization of all 12 aerospace and defense companies on the S&P 500, including RTX Corp, Boeing Co., Northrop Grumman Corp, and GE Aerospace, which total roughly $1.5 trillion.

Segment Performance And AI Contracts

Starlink generated approximately $11.4 billion in revenue during 2025, accounting for 61% of SpaceX's total revenue. The satellite internet unit produced operating income of about $4.4 billion on margins of roughly 36%, supported by more than 10 million subscribers across 164 countries. SpaceX's launch services business generated an estimated $4 billion in revenue, while Starship development consumes about $3 billion annually in research and development spending. Newly disclosed AI data-compute contracts with Anthropic and Alphabet Inc's Google are expected to contribute significantly, with Anthropic paying about $1.25 billion a month and Google about $920 million a month.

Criticism And Political Commentary

The milestone drew criticism from economists and lawmakers. Economist Peter Schiff noted that while Musk surpassed J.D. Rockefeller as the richest private citizen ever, Rockefeller earned about $2 billion per year in real income adjusted for inflation, whereas "Musk earns nothing." Schiff attributed the wealth disparity to a market bubble. Economist Robert Reich criticized the IPO as the "universe's largest Ponzi scheme," arguing it forced participation. Democratic lawmakers, including New York City Mayor Zohran Mamdani and California Gov. Gavin Newsom, highlighted the wealth gap, with Mamdani citing the event as a reason to tax the ultra-wealthy.
