Will SpaceX's $1.75 Trillion IPO Filing Ignite a Rally Across Aerospace Peers Like RKLB and LMT?
Multiple outlets reported on March 30, 2026, that Elon Musk's SpaceX has filed confidentially for an IPO, potentially valuing the company at $1.75 trillion in what could be one of history's largest public offerings. The news triggered immediate lifts in publicly traded aerospace and space stocks, with Rocket Lab (RKLB) jumping over 10% in a single session amid broader sector optimism. As SpaceX eyes a blockbuster debut—far surpassing the topic's $75B+ raise projection—this catalyst underscores the commercial viability of space ventures, but raises questions about how the windfall ripples through competitors and incumbents.
Rocket Lab's Launch Momentum Amid SpaceX Shadow
Rocket Lab, a leader in small satellite launches, stands as the purest public play on the burgeoning space launch market. With a market cap of $38.3 billion, RKLB trades at a lofty 59.7x trailing sales despite negative EBITDA margins of -28.5%, reflecting high growth expectations. Revenue grew 38% TTM, fueled by a $1.85B backlog including hypersonic tests and ESA missions. Recent news highlights include a $190M DoD contract for 20 HASTE launches and Q4 2025 revenue of $180M (up 38% YoY).
RKLB's Electron rocket has achieved 85 missions, positioning it as a reliable alternative to SpaceX's rideshare dominance. SEC filings consistently name SpaceX as a top competitor in dedicated launches, yet Rocket Lab differentiates via customization and rapid cadence from sites in New Zealand and Virginia. Since September 2024, RKLB shares have surged from ~$5 to $67, a 1,200%+ gain, with 1M return at +2% but 3M at +32%.
| Metric (TTM) | RKLB |
|---|---|
| Market Cap | $38.3B |
| PS Ratio | 59.7x |
| Revenue Growth | +38% |
| EBITDA Margin | -28.5% |
| Price Return 1M/3M/YTD | +2% / +32% / -6% |
Bull Case: SpaceX IPO validates the sector, boosting RKLB's valuation multiple as it scales Neutron (medium-lift) amid $2B+ backlog. Bear Case: SpaceX's scale crushes pricing power for small launches.
Lockheed Martin: Defense Anchor in Expanding Space Race
Lockheed Martin (LMT), with a $142B market cap, offers stability via its defense roots. Trading at 28.7x earnings and 1.9x sales, LMT boasts 11.6% EBITDA margins and 5.7% revenue growth TTM. YTD price return stands at +30%, with 3M gains of +36%.
LMT's space division benefits indirectly from commercial tailwinds, as seen in missile production ramps and hypersonic investments overlapping with Rocket Lab partnerships. While not a pure space play, SpaceX's Starshield (gov't Starlink variant) could pressure LMT's satellites, but diversified revenue (aero/defense) shields it.
| Recent Price Action (Daily, Apr 2026) | LMT Adj Close | Change % |
|---|---|---|
| 2026-04-01 | 617.73 | +2.2% |
| 2026-03-31 | 604.39 | +1.0% |
| 2026-03-30 | 598.57 | -2.8% |
Bull: IPO hype accelerates DoD space budgets. Bear: Budget cuts amid fiscal pressures.
Boeing's Tumultuous Recovery in Aerospace
Boeing (BA), at $165B cap, trades at 88.5x earnings (reflecting losses) but 1.8x sales with 34% revenue growth TTM and 8.2% EBITDA margin. Shares hover ~$210, down 13% 1M but up YTD amid Starliner delays.
BA's space arm competes via SLS/Starliner, but SpaceX's crewed missions (Crew Dragon) have won NASA contracts. FY2025 revenue hit $89B (up from $66B FY2024), with net income swinging to $2.2B from losses. Still, $43B net debt looms.
| BA Financial Trajectory (Recent FY/Q) | Revenue ($B) | Net Income ($B) | FCF ($B) |
|---|---|---|---|
| FY2025 | 89.5 | 2.2 | -1.9 |
| FY2024 | 66.5 | -11.8 | -14.4 |
| FY2023 | 77.8 | -2.2 | 4.4 |
Bull: SpaceX IPO spotlights commercial aero recovery. Bear: Ongoing quality issues cap upside.
Virgin Galactic: Tourism Laggard Facing Headwinds
Virgin Galactic (SPCE), micro-cap at $155M, epitomizes space tourism risks. PS ratio 100x with -78% revenue plunge TTM; shares ~$2.50, down 25% YTD. Delta flights paused, competing with Blue Origin (pausing too).
SEC notes SpaceX/Blue Origin as threats shifting to suborbital. No near-term profitability.
Bull: Sector halo lifts speculative plays. Bear: Cash burn and delays doom it.
Investment Thesis: Sector Tailwind with Selective Winners
SpaceX's IPO—potentially raising $75B+ at $1.75T val—affirms space's trillion-dollar potential, spilling into publics via sentiment and capex. RKLB leads as growth proxy (buy dips below 50x PS), LMT/BA as stables (LMT preferred). SPCE remains high-risk.
Market misprices RKLB's backlog execution; at 60x sales, it's rich but justified by 38% growth vs. peers' single digits.
Catalysts to Monitor
- SpaceX IPO Pricing: Success could add 20-50% to sector multiples.
- RKLB Neutron Debut: First flight H2 2026; backlog $1.85B (current: FY2025Q4 equiv.).
- DoD Budget: Hypersonics/space defense spend amid rivalry.
Stance: Overweight RKLB/LMT; underweight BA/SPCE. SpaceX unlocks the stars—for some.
