Space Stocks Selloff: Why $PL, $LUNR, $SATL, $ASTS and $RKLB Are Falling Together After June’s Rally

Planet Labs is not selling off because its latest operating update was weak. In fact, the most recent company data was strong. Planet reported first-quarter fiscal 2027 revenue of approximately $94 million, up 42% year over year, with remaining performance obligations increasing 81% year over year to roughly $816 million and backlog rising 72% year over year to more than $906 million. The company also reported cash, cash equivalents and short-term investments of roughly $731 million, up sharply year over year.

That is why the stock is a useful case study. If a company can report record revenue and still get pulled into a sector selloff, the problem is not a simple “bad earnings” story. The problem is valuation and timing. Planet has become one of the clearest public-market ways to play Earth observation and geospatial data, but after a powerful rally, investors are asking whether the company’s growth rate, government demand and backlog conversion are enough to defend the multiple.

What the market is probably discounting

• Planet has a real data platform, but investors want proof that backlog and RPO growth can translate into durable margins and free cash flow.
• Government and defense demand is supportive, but contract timing can be uneven and headlines do not always equal immediate revenue recognition.
• The stock had become a major space-data proxy. That helps during thematic inflows and hurts during thematic exits.
• At a market cap above $9 billion in the snapshot, the market is no longer treating Planet as a speculative microcap; it is demanding a growth-company standard.

Planet’s bull case is still straightforward: a large proprietary satellite-data archive, recurring annual contract value, defense/government relevance, crisis-monitoring use cases and machine-learning-ready data in a world where AI and national security increasingly need persistent Earth intelligence. The bear case is also clear: if growth normalizes or margin expansion disappoints, the stock can compress because the narrative premium had expanded too quickly.

Intuitive Machines has some of the strongest recent operating headlines in the group. In May, the company reported record first-quarter 2026 revenue of $186.7 million, nearly triple the prior-year period, driven by the Lanteris acquisition and continued execution across CLPS, OMES and NSNS programs. It also reported positive adjusted EBITDA of $2.7 million and ended the quarter with a record backlog of $1.1 billion.

The company then added more strategic depth. It announced a definitive agreement to acquire Goonhilly Earth Station and COMSAT, expanding its space-to-Earth network and communications infrastructure. Shortly after, Intuitive Machines announced two prime lunar reconnaissance contracts: a $15.5 million three-year cost-plus-fixed-fee contract for LROC operations and a $4.5 million three-year contract for ShadowCam operations.

Why the stock can still fall despite good news

LUNR has moved from “lunar mission story” to “space infrastructure platform.” That is attractive, but it also raises the execution bar. The market now has to judge whether acquisitions, NASA task orders, lunar data services and cislunar communications can be integrated into a scalable, margin-generating business. When the whole space basket sells off, LUNR’s positive headlines may not protect it because investors are also watching dilution risk, acquisition integration, contract concentration and insider-sale optics.

• Backlog is real and large, but investors will monitor the pace of revenue conversion and margin quality.
• NASA-related work validates the platform, but government contracts can be milestone-driven and politically sensitive.
• The company is expanding rapidly through acquisitions, which can create integration risk.
• Form 144 filings do not automatically imply bearish insider behavior, but in a volatile space stock they can damage short-term sentiment.

LUNR’s setup is therefore not “bad company, bad stock.” It is more nuanced: strong operational expansion, but a stock that became exposed to both space-sector de-risking and the market’s demand for cleaner proof that lunar infrastructure can become a repeatable business rather than a sequence of high-profile contracts.

Satellogic is the most fragile name in this basket because it combines a compelling narrative with smaller size, higher volatility and lower tolerance for uncertainty. The company’s latest developments are not negative. On June 23, Satellogic and SynMax announced a partnership to bring persistent global intelligence to defense customers, combining Satellogic’s high-resolution, high-frequency Earth observation with SynMax’s multi-source intelligence fusion.

Earlier in June, Satellogic appointed Lieutenant General (Ret.) Michael E. Williamson to its board, and in late May the company announced an $18 million contract for persistent Earth observation monitoring. Those developments all point in the same direction: Satellogic is trying to position itself as a defense/intelligence infrastructure company rather than simply an imagery provider.

Why SATL is being punished harder

When the market is in risk-on mode, a small Earth-observation name with defense exposure can move violently upward. When the sector reverses, the same characteristics become liabilities. Investors may like the direction of Satellogic’s strategy, but they will not treat partnerships and board additions the same way they treat recurring revenue, backlog visibility, cash runway and margin expansion.

• The SynMax partnership improves the defense/intelligence narrative but does not by itself define revenue magnitude.
• The $18 million contract is meaningful for a smaller company, but the market wants repeatability and scale.
• Liquidity risk makes SATL more vulnerable when space ETFs, momentum traders or retail holders exit the theme.
• Execution risk is higher because the company must prove it can turn satellite data into durable customer economics.

SATL may offer one of the most asymmetric narratives in the group, but it also carries one of the highest “prove it” burdens. In a June selloff, the market is not rewarding optionality; it is penalizing uncertainty.

AST SpaceMobile remains one of the most ambitious public-market space stories. The company’s mission is not incremental: it aims to build a space-based cellular broadband network that connects directly to ordinary smartphones. In June, the company achieved an important operational milestone when BlueBirds 8, 9 and 10 reached low Earth orbit aboard a SpaceX Falcon 9. On June 23, AST announced that BlueBirds 11, 12 and 13 are scheduled to launch in the first half of August, also aboard Falcon 9 from Cape Canaveral.

This is exactly the type of operational progress that should matter. The problem is that ASTS is no longer valued like an early speculative concept. With a market cap around $19 billion in the snapshot used here, the market is demanding execution consistency, not just proof of concept. The stock is vulnerable because its long-term value depends on launch cadence, satellite manufacturing throughput, network performance, regulatory clearances, commercial activation and partner monetization.

Why SpaceX is complicated for ASTS

SpaceX is a partner because Falcon 9 is launching AST satellites. But SpaceX is also a perceived competitor because Starlink’s direct-to-cell ambitions sit near the same investor imagination. The technologies, spectrum relationships and commercial models are not identical, but the market often simplifies the trade: if SpaceX dominates satellite broadband and launch, ASTS must prove why its operator-partner model and direct-to-device architecture can still command a major share of the opportunity.

• ASTS has strong telecom-partner visibility, including major mobile network operator relationships.
• The company must keep launching satellites on schedule to defend the commercial-service timeline.
• Q1 2026 revenue of $14.7 million was far below the company’s long-term ambition, so the stock is valued on future execution rather than current revenue.
• Any launch delay, satellite issue or competitor headline can have outsized impact because the valuation is already large.

In a bull market, ASTS is one of the cleanest “space connectivity” stories. In a de-risking market, that same purity becomes dangerous because the equity depends heavily on future milestones. The June selloff is the market forcing the story from “massive TAM” back toward “show me deployment.”

Rocket Lab has arguably the strongest operating base among the public space names in this report. The company reported first-quarter 2026 revenue above $200 million, surpassed guidance metrics, posted a backlog above $2.2 billion and guided for another record revenue quarter. It also signed a large number of new launch contracts, including a major launch agreement involving Neutron and Electron missions.

The company also delivered one of the strongest operational headlines in the sector in June: a U.S. Space Force tactically responsive space mission launched on Electron with only 16 hours and 42 minutes’ notice, surpassing prior records. That is a powerful defense-space validation signal. It shows Rocket Lab is not only a launch provider, but a vertically integrated space-systems contractor capable of fast-response national-security missions.

Why RKLB can fall despite strong execution

Rocket Lab has two valuation identities. It is an operating company with real revenue, contracts, launches and backlog. But it is also the most obvious public-market SpaceX comparison in launch and space systems. That comparison gives it premium status when investors are searching for SpaceX proxies. It also creates risk when SpaceX volatility or valuation reset spills into the rest of the sector.

• Electron continues to validate Rocket Lab’s launch execution, especially in responsive defense missions.
• Neutron remains central to the long-term bull case because it would move Rocket Lab into larger reusable launch competition.
• Any delay or technical uncertainty around Neutron can weigh disproportionately because the market sees it as the SpaceX/Falcon alternative angle.
• At a snapshot market cap above $49 billion, Rocket Lab must keep growing into a very large valuation.

Rocket Lab is not being sold because the operating story is weak. It is being sold because the market is resetting the price it is willing to pay for future dominance. The stronger the company becomes, the more investors compare it directly with SpaceX — and that creates both upside and pressure.
