SpaceX Files $1.75 Trillion IPO: Everything You Need to Know About SPCX

SpaceX filed its S-1 registration document with the SEC on May 20, 2026, officially beginning the process for what analysts are calling the largest IPO in history. The company is targeting a $1.75 trillion valuation with a planned raise of up to $75 billion under the ticker symbol SPCX, set to trade on the Nasdaq in mid-June. Here's everything you need to know before the roadshow kicks off on June 8.

Key Numbers From the S-1

The filing reveals a company with serious revenue momentum but also significant complexity from recent mergers:

• 2025 total revenue: $18.7 billion, up 33% from $14.1 billion in 2024
• Starlink revenue: $11.4 billion — 61% of all SpaceX revenue
• Q1 2026 revenue: $4.694 billion
• Q1 2026 operating loss: $1.943 billion
• Q1 2026 adjusted EBITDA: $1.127 billion
• Target raise: $75 billion (more than doubling the previous IPO record)
• Valuation: $1.75 trillion
• Total addressable market: $28.5 trillion, spanning satellite internet, launch services, and space exploration

The $1.943 billion operating loss in Q1 2026 is largely attributable to xAI's operations — SpaceX merged with Elon Musk's AI company xAI in February 2026, which had already absorbed X (formerly Twitter) in March 2025.

Starlink Is the Real Business

The filing confirms what insiders have long suspected: Starlink is SpaceX's growth engine, not rocket launches. At $11.4 billion in 2025 revenue representing 61% of total revenue, the satellite internet service dwarfs the launch business in financial terms. Starlink has expanded aggressively to rural markets, maritime, and aviation customers, building the kind of recurring revenue base that traditional aerospace companies don't have.

The IPO is essentially a bet on Starlink's continued growth trajectory more than it is on future Mars missions or reusable rockets — even if those are the headline-grabbing parts of the S-1's narrative.

The xAI Complication

The February 2026 merger between SpaceX and xAI complicates the financial picture considerably. xAI was a rapidly growing but loss-making AI company, and its results are now consolidated into SpaceX's financials. This is the primary driver of the Q1 operating loss, even as adjusted EBITDA remains positive.

Investors need to evaluate SpaceX as a combined entity: a profitable satellite internet business subsidizing an AI operation that is burning cash to compete with OpenAI and Anthropic. The S-1 notes this explicitly as a risk factor. The xAI segment includes Grok (the AI assistant), the Colossus supercomputing cluster, and X's social platform.

How to Buy SpaceX Shares (SPCX)

For retail investors, SpaceX is specifically making shares available through five brokerages:

• Charles Schwab
• Fidelity Brokerage Services
• Robinhood Financial
• SoFi Securities
• E*TRADE by Morgan Stanley

The IPO roadshow begins June 8, with trading expected to start around June 12 on the Nasdaq. Shares will also dual-list on Nasdaq Texas, which offers certain regulatory advantages.

Interested investors should open or verify accounts at these brokerages ahead of time.

Valuation Context: Is $1.75 Trillion Justified?

For reference, at $1.75 trillion, SpaceX would rank among the five most valuable companies in the world. The valuation math relies heavily on Starlink's future growth:

• Starlink has roughly 7 million subscribers globally as of early 2026
• The satellite internet TAM is estimated to be in the hundreds of billions
• SpaceX's launch monopoly in reusable rockets creates barriers to competition

Bears will point to the xAI losses, Musk's divided attention across Tesla, X, and government roles, and the regulatory risk of being so intertwined with US government launch contracts. The $28.5 trillion total addressable market figure in the filing (which covers everything from space tourism to interplanetary colonization) is ambitious to put it diplomatically.

Risks Worth Knowing

The S-1 flags several key risks:

• xAI losses: The AI operation is loss-making and competing in an expensive sector
• Regulatory dependence: SpaceX relies heavily on government launch contracts and FCC licensing for Starlink
• Musk concentration risk: Elon Musk controls the company; his involvement in other ventures is cited as a distraction risk
• Launch economics: The business requires continuous successful launches to maintain revenue momentum
