SpaceX IPO: Inside the $75B Filing, Starship Flight, and Analysts’ Biggest Red Flags

For the first time, the filing forced SpaceX to open its books to public scrutiny. The numbers are staggering on both sides of the ledger. The company generated $18.7 billion in revenue in 2025, with Starlink accounting for $11.4 billion — or 61% — of the total . But SpaceX also posted a $4.9 billion net loss for the year, followed by a $4.28 billion net loss in the first quarter of 2026 alone. The company’s accumulated deficit now stands at $41.3 billion .

The deepest hole is in artificial intelligence. Following an all-stock merger with Elon Musk's xAI in February 2026, the combined entity is burning roughly $2.5 billion per quarter on AI-related expenses, with Q1 2026 capital expenditures on AI reaching $7.7 billion — far outpacing the $1 billion spent on its Space segment and $1.3 billion on Connectivity .

Starship V3: A Pre-IPO Confidence Signal

Two days after the S-1 filing, SpaceX launched the first flight of Starship Version 3 — a 408-foot-tall vehicle with upgraded Raptor V3 engines — from a newly constructed second launch pad at Starbase, Texas . The timing was critical. A successful test would serve as a powerful signal to institutional investors that the company’s core launch technology was maturing on schedule.

The flight met most of its primary objectives. The V3 Starship reached its intended suborbital trajectory, deployed 22 mock Starlink satellites, transmitted real-time video during the flight, and executed a controlled splashdown in the Indian Ocean . Elon Musk congratulated his team on "an epic first Starship V3 launch and landing" .

However, the flight was not flawless. Three Raptor engines on the Super Heavy booster failed at liftoff, and the booster itself did not complete a controlled boostback burn, instead splashing down uncontrolled in the Gulf of Mexico. Starship also lost one vacuum Raptor engine during ascent, and a planned in-space engine re-ignition test was not performed . The mixed results underscore that while Starship is advancing, it remains an experimental vehicle central to SpaceX’s long-term plans but far from proven in operational service.

Global Space Stock Rally

The gravitational pull of the SpaceX IPO has lifted the entire sector. In the U.S., retail-driven enthusiasm sent pure-play space stocks soaring, with Planet Labs surging 24% and Intuitive Machines gaining 24% over two trading days following the initial confidential filing in April .

The rally quickly crossed the Atlantic. On May 21, the day after the public S-1 filing, French satellite operator Eutelsat jumped 16% to 20%, while German manufacturer OHB gained 12% to 15% . Luxembourg-based SES rose 2.3% to 3.7%. By the end of the week, Eutelsat and OHB had each added roughly a third to their market value . British space investment firm Seraphim Space has surged nearly fourfold over the past year, trading at a 71% premium to its per-share asset value .

The rally reflects a convergence of forces: the landmark IPO, expanding global defense budgets, and a McKinsey projection that the global space economy will reach $1.8 trillion by 2034, up from $613 billion in 2024 .

What Analysts Are Flagging

Extreme Valuation vs. Fundamentals

A $1.75–$2 trillion valuation on a company that has never posted an annual profit is attracting comparisons to the most speculative peaks of tech IPO history. The implied multiple dwarfs every aerospace and satellite peer. One analysis calculated that only about 7% of the company’s implied valuation is backed by current tangible equity, given the massive accumulated deficit .

Elon Musk’s Governance Structure

The S-1 discloses that Musk holds 42% of the equity but commands 85.1% of the voting rights, giving him unilateral control over board composition, strategic direction, and any related-party transactions . Two performance-based awards tied to Musk could be worth roughly $737 billion if fully vested . For institutional investors, this concentration of voting power is a classic governance red flag.

Starlink Revenue Concentration

Starlink generated 61% of SpaceX’s total 2025 revenue, making the company’s financial health heavily dependent on a single product line that faces intensifying competition from Amazon’s Project Kuiper and other emerging low-Earth-orbit constellations . Any regulatory setback, spectrum dispute, or technical failure affecting Starlink would directly hit the company’s core revenue engine.

Starship Execution Risk

Starship is the vehicle on which SpaceX’s interplanetary ambitions and high-volume satellite deployment plans depend. The V3 test flight demonstrated progress, but the engine failures and booster control issues highlight that the system is still in development. Transitioning Starship from experimental flights to reliable commercial operations — particularly for missions involving human crews or high-value payloads — remains a significant technical challenge.

Narrow IPO Window

SpaceX is targeting a tight pricing and listing window in early June. The roadshow is compressed, and any macroeconomic disruption, volatility spike, or last-minute SEC comment between now and June 12 could force a delay or pressure the final pricing.

The next two weeks will determine whether the market is willing to price SpaceX as a $2 trillion company — or whether the weight of its losses forces a more conservative debut.
