3 Space Stocks To Watch Amid Elon Musk’s SpaceX IPO Hype

SpaceX’s anticipated $1.75 trillion initial public offering this summer will force institutional investors to reprice the entire commercial space sector against audited financial data for the first time, triggering material revaluations across publicly traded space stocks whose valuations currently rest on speculation rather than comparable benchmarks. The filing of SpaceX’s public S-1 document in late May and expected listing in late June or July will reveal launch economics, Starlink profitability, and cost structure that no competitor has yet disclosed at scale.

• SpaceX S-1 filing due late May 2026, with IPO listing slated for late June or early July at $1.75 trillion valuation
• Rocket Lab Q1 2026 revenue hit $200.3 million, up 63.5% year-over-year, with $2.2 billion backlog and Q2 guidance at $235 million
• RKLB stock fell 7.17% despite beating Q2 guidance, signaling profit-taking ahead of SpaceX disclosure of comparable operational metrics

• $1.75T SpaceX valuation in anticipated IPO versus prior private round pricing
• $200.3M Rocket Lab Q1 revenue, growing 63.5 percent year-over-year versus Q1 2025
• 63.5% Rocket Lab year-over-year revenue growth rate versus prior year quarter

The commercial space sector trades today without a single public company disclosing full launch economics or satellite constellation profitability at scale. SpaceX’s entry into the public markets will eliminate that opacity.

When the company files its S-1 with the Securities and Exchange Commission in late May, investors will see audited revenue figures for launch services, the cost structure behind Falcon 9 and Falcon Heavy flights, and the unit economics of Starlink, which has never published operational margins.

That disclosure will establish the first institutional-grade benchmark for pricing the entire supply chain beneath the space economy.

For portfolio managers holding space sector exposure through publicly traded equities, the timing creates a critical window. Valuations of launch providers, spacecraft manufacturers, and components suppliers are currently anchored to analyst estimates and management guidance rather than peer-to-peer comparison.

Rocket Lab, the only publicly traded company building launch vehicles and spacecraft in-house, sits at the center of that repricing. When SpaceX publishes real numbers, every metric Rocket Lab investors have relied on to justify current valuations will be tested against a more rigorous standard.

Rocket Lab’s Quarterly Earnings Crush Guidance but Stock Sells Off Ahead of SpaceX Disclosure

Rocket Lab reported first-quarter 2026 results that beat consensus on revenue and delivered upside guidance for the second quarter, yet the stock declined 7.17% to $78.58 immediately after earnings. The company posted revenue of $200.3 million against analyst estimates of $189 million, representing 63.5% year-over-year growth.

Backlog expanded to $2.2 billion, up 20% quarter-over-quarter, and the company signed 31 new Electron and HASTE contracts plus five Neutron launch agreements.

Q2 guidance of $235 million in revenue exceeded consensus expectations of $205 million by nearly 15%, a substantial beat on forward guidance. Earnings per share came in at negative $0.07 versus the negative $0.08 estimate, and gross margins reached 39% compared to the 40% consensus forecast.

By every fundamental measure, the quarter reinforced Rocket Lab’s operational trajectory and market positioning. The stock’s immediate selloff suggests investors liquidated positions into strength rather than allowing fundamentals to drive price appreciation.

The profit-taking reflects the stock’s 240% year-over-year performance entering the quarter, signaling institutional rotation rather than deteriorating business fundamentals.

Technical positioning shows RKLB held support at its 20-day exponential moving average near $78.96, with the 50-day EMA at $75.52 providing a secondary support level. The prior high of $94.40 was rejected at the 0.618 Fibonacci level, establishing a recent intermediate resistance zone.

A decisive break below the 20-day EMA on March 26 had triggered a 19.31% decline, and repeated violation would open downside targets at $70.71, $62.45 (the 200-day EMA), and $56.08 at the channel floor.

Options market positioning tilted bullish into the SpaceX filing window, with the put-call ratio at 0.53 versus 0.73 at the prior $0.07 earnings miss, indicating traders were buying call contracts despite near-term selling pressure.

SpaceX S-1 Disclosure Will Establish First Publicly Audited Benchmark for Space Sector Valuation

Rocket Lab’s position as the closest public proxy to SpaceX makes the IPO timing material to institutional crypto and venture investors who hold exposure through traditional equities or derivatives tied to space sector performance. The company competes directly with SpaceX in launch services, satellite manufacturing, and propulsion systems development.

When SpaceX publishes its S-1 filing, three categories of information will enter public record for the first time: launch revenue per flight, the cost basis for manufacturing and operating Falcon 9 and Falcon Heavy vehicles, and Starlink subscription revenue alongside subscriber acquisition costs and churn rates.

That disclosure framework will force a recalibration of how investors model launch provider margins, spacecraft production economics, and satellite constellation business models. Rocket Lab’s $2.2 billion backlog will be evaluated against SpaceX’s disclosed contract pipeline and pricing.

The company’s 39% gross margin on Q1 revenue will be benchmarked against SpaceX’s margin profile across its mixed revenue portfolio. For the first time, investors will have audited data rather than confidential management estimates to anchor valuation multiples.

The SEC-mandated disclosure of SpaceX’s audited financials eliminates the valuation arbitrage that currently benefits smaller public space companies trading on speculation.

AST SpaceMobile represents a different exposure vector within the space sector repricing. The company operates the only US satellite network that connects directly to standard smartphones without requiring special hardware, with anchor partnerships from AT&T, Verizon, and FirstNet.

This positioning addresses a market segment that SpaceX’s Starlink does not currently service, creating a non-overlapping business model. When SpaceX files its S-1, the market will assess whether satellite-to-smartphone connectivity represents a distinct value pool or a feature that SpaceX might commercialize as an add-on to its existing Starlink infrastructure.

SpaceX Public Financials Will Establish Valuation Ceiling for Competing Launch Providers and Supply Chain

The $1.75 trillion valuation SpaceX is expected to command at IPO establishes a critical reference point for pricing the broader space sector. A company valued at $1.75 trillion generates an implied revenue multiple that can be applied backward to Rocket Lab’s $200.3 million quarterly revenue run rate and $2.2 billion backlog.

If SpaceX trades at a multiple that reflects its Starlink growth trajectory and launch provider market position, that same multiple applied to Rocket Lab’s backlog and growth rate will produce a target valuation for institutional comparison.

The institutional capital flowing into SpaceX at the IPO will simultaneously validate or invalidate the investment thesis for publicly traded space companies. If SpaceX’s audited financials reveal higher margins than consensus estimates, public space stocks will likely reprice upward on the same thesis.

Conversely, if cost pressures or competitive intensity reduce SpaceX’s profitability below market expectations, valuations of smaller providers will compress. The repricing mechanism works bidirectionally, but the disclosure of real financial data creates a rational anchor point that speculation cannot sustain once the market sees actual numbers.

Rocket Lab management has signaled confidence in the company’s competitive position by maintaining Q2 guidance at $235 million despite the SpaceX IPO announcement. The company’s Neutron rocket program, currently in development, is designed to compete with medium-lift launch demand in a lower-cost envelope than Falcon 9. However, SpaceX’s disclosed cost
