Musk: SpaceX Could Be Worth More Than the Rest of Earth

Elon Musk said SpaceX could eventually be worth more than the rest of Earth if the company hits its long-term multiplanetary goals. SpaceX shares are already trading around a $2 trillion market cap after the largest IPO in history, so the claim is landing in a market that is actively pricing the vision.

What Musk actually said

The comment came in reply to an X user questioning the strategic logic of the reported Anthropic and SpaceX AI compute deal. Musk wrote, “You don’t seem to understand that SpaceX will be worth more than the rest of Earth if we accomplish our goals.”

The post drew 2.4 million views within hours. It was not accompanied by a forecast, financial model, or estimated date.

The Anthropic compute deal behind the tweet

Anthropic signed a major compute leasing agreement with SpaceX in May 2026 for access to Colossus 1, the Memphis AI supercluster built by xAI to train Grok models, granting Anthropic access to more than 220,000 NVIDIA GPUs and over 300 MW of power at roughly $1.25 billion per month.

SpaceX filings described a multi-year ramp through May 2029, implying a possible $30 billion to $40 billion value, though Musk later said the base lease runs 180 days with a 90-day mutual termination notice afterward.

SPCX stock: from record IPO to pullback

SpaceX completed its IPO on June 12, 2026, pricing shares at $135, raising $86 billion, and reaching roughly $2.1 trillion in market value on its first Nasdaq trading day. Shares climbed 50% to an all-time high of $225.64 on June 16 before concerns grew over a bond offering, heavy Terafab data center spending, and upcoming insider lockup expirations.

SpaceX shares fell 26% from the high, touched $145.20, then recovered slightly to hover around $152, and the company also entered the Nasdaq-100 on July 7, triggering about $4.3 billion in passive inflows.

The revenue math analysts are using

Morgan Stanley put revenues at $330 billion by 2030, though Musk publicly pushed back and said $1 trillion is more realistic for that year, with analysts projecting revenues approaching $100 billion as early as 2028, driven by Starlink’s satellite broadband network, AI compute layered on top, and SpaceX’s vertical control of its own launch infrastructure.

Morgan Stanley’s Adam Jonas is bullish on SpaceX, predicting revenue of $3.3 trillion by 2040 and potential for growth in AI.

Starmind and the AI satellite angle

On Thursday, SpaceX also revealed renderings of its AI1 satellite, part of its Starmind constellation dedicated to AI compute, with a 150 kW peak compute payload, an average payload compute of 120 kW, a wingspan of 70 meters, and a 150 kW solar array.

The Starmind constellation will be interconnected via laser links, which will beam AI compute back to the Earth’s surface via its Starlink satellite internet service.

Options market and stocks to watch

Watch for continued volatility in SPCX as the market weighs Musk’s vision against lockup expirations and heavy capex on data centers.

Watch NVDA given the Colossus supercluster’s reliance on more than 220,000 GPUs and any read-through to hyperscaler demand.

Watch TSLA for spillover on any renewed Tesla and SpaceX consolidation chatter that analysts have floated.

Watch smaller space names like ASTS, which has been pressured as capital rotates toward SPCX. For related coverage, see other news.
