The week the space trade cooled: SpaceX rotation, insider selling and the Planet Labs case

01The thesis: a reset, not a rupture

For most of 2025 and the first half of 2026, space stocks were one of the market’s loudest stories. Launch, satellites, defence and communications names ran hard, some of them multiplying in months. So when a cluster of them fell together this week – Rocket Lab down about 7%, AST SpaceMobile about 5%, Intuitive Machines about 3% – the instinctive question was: what broke? The honest answer is almost nothing broke at the business level. What changed was the price of the story.

This editorial argues that the pullback is best read as a reset of sentiment and valuation, layered on top of a structural event – the arrival of SpaceX on the public market – and amplified by scheduled insider selling. It is the classic behaviour of a young, high-beta sector after a vertical run: the direction of the tape changes faster than the fundamentals do. The one genuine exception is Planet Labs, whose fall has a specific corporate cause and should not be lumped in with the others.

02The run and the snap

Context matters, because the size of the fall only makes sense against the size of the climb. In the week ending July 2, Rocket Lab had risen roughly 25% and AST SpaceMobile roughly 30%. These are not the moves of sleepy blue chips; they are the moves of momentum names carried by narrative and by flows. A pullback of a handful of percent after gains like that is not a crash – it is gravity.

There was no confirmed stock-specific catalyst behind the broad move. That absence is itself the point: when a sector sells off with no bad news, the seller is usually the price, not the business. Profit-taking concentrated in the highest-beta names, some cooling in retail engagement – a widely shared social-media post celebrating Rocket Lab gains is exactly the kind of thing that marks local exhaustion – and the tape did the rest.

It is worth naming the levels, because they frame the drama. Rocket Lab slipped to around $93 from a stock that had been flirting with triple digits; AST SpaceMobile eased to about $80.6; Intuitive Machines to roughly $18.9. None of these are broken charts – they are strong charts taking a breath. In momentum names, the first sharp pullback after a vertical run is often less a reversal than a test of who bought for the story and who bought for the trade; the former tend to sit tight, the latter tend to sell first and ask questions later.

03The SpaceX factor: the IPO that changed the rules

The structural driver sitting underneath the week is SpaceX. On June 12, 2026, SpaceX completed the largest IPO on record: priced at $135 a share, it raised roughly $85.7 billion by selling about 638.9 million Class A shares, at an IPO valuation near $1.77 trillion. On its first full day it jumped about 20% and touched a market capitalisation around $2.1 trillion, making it one of the most valuable U.S.-listed companies in existence. Notably, roughly 30% of the offering was steered to retail investors, unusually high for a deal this size.

Why does this drag on the smaller names? Because for years, investors who wanted exposure to the space economy could not buy the crown jewel – SpaceX was private. So they bought proxies: Rocket Lab for launch, AST SpaceMobile for space-based connectivity, Planet Labs and Satellogic for Earth imaging. The proxies carried a scarcity premium. Now the real thing is buyable, with Starlink generating roughly 61% of SpaceX’s 2025 revenue – about $11.4 billion, up around 50% year over year – and more than 10 million active customers. Part of the capital that lived in the proxies is simply going home to the original.

Governance matters for the flow story too. After the IPO, Musk retains about 42% of the shares but roughly 82% of the voting power through super-voting stock, so control is not in doubt even with a vast public float. That combination – a founder firmly in charge and a huge, liquid, widely held stock – makes SpaceX both the reference asset for the sector and a magnet for the attention that used to spread across the smaller names.

04Insider selling: the CEO who sold into strength

There is a second, more concrete weight on Rocket Lab specifically, and it is the same detail that appeared in this week’s Merlintrader Insider Weekly: CEO Peter Beck sold roughly $286 million of stock across three days. In dollar terms it was the single largest insider sell cluster of the week across the whole U.S. market. These sales appear to be scheduled and pre-planned, the kind executives use to diversify after a stock has run – not a statement about the company’s prospects.

But the market does not always read nuance in real time. A very large CEO sale, printed while the sector is already cooling, reinforces the narrative of a top and gives momentum sellers a story to point to. This is the paradox of insider data that the Insider Weekly is built around: a sale can be perfectly benign in intent and still weigh on sentiment in the moment.

The broader pattern is worth watching across the sector, not just at Rocket Lab. After a vertical run, it is normal for founders, early venture backers and pre-IPO holders to trim – through scheduled plans or post-lock-up sales – simply because paper wealth has ballooned. That supply of stock is a headwind independent of fundamentals, and it tends to arrive precisely when prices are high and sentiment is hot. Reading insider activity means separating this mechanical, valuation-driven selling from the rarer, more meaningful signal of insiders buying with their own cash.

05The Planet Labs case: the exception that proves the rule

Not every name in this pullback is telling the same story. Planet Labs is down about 37% over the past month, far more than the sector move, and the reason is genuinely company-specific rather than a rotation effect. On its recent earnings call the company disappointed on two fronts at once. First, guidance: it guided full-year gross margin down from about 56% in the first quarter to a 52-54% range, flagged heavy capital investment of roughly $80-95 million for the year, and set full-year revenue at about $425-441 million – a picture of decelerating growth with adjusted EBITDA guided to breakeven at best.

Second, and more powerful, dilution: on the same call Planet Labs announced an at-the-market equity programme of up to $1.5 billion, allowing it to sell Class A shares over time to fund manufacturing capacity and Earth-imaging infrastructure. For a stock that had been up around 162% year to date into June – past $51 a share, helped by strong contract wins and a partnership with Nvidia – the combination of softer margins and a large potential share overhang was enough to trigger a violent de-rating. That is not the SpaceX rotation; that is a company resetting its own expectations.

06The Rocket Lab paradox: a mega-deal, and the stock still fell

If you wanted a single piece of evidence that this week was about sentiment and not fundamentals, look at Rocket Lab. Just days before the pullback, on June 29, it announced one of the most ambitious moves in the sector’s history: an agreement to acquire Iridium Communications for an enterprise value of roughly $8.0 billion, paying $54 per share ($27 in cash and the rest in stock), with about $3.6 billion of financing from Deutsche Bank and Wells Fargo and a targeted close in mid-2027.

Strategically, the deal is a landmark: it fuses Rocket Lab’s launch and satellite-manufacturing capabilities with Iridium’s global satellite-communications network, its L-band spectrum and its 500-plus partner ecosystem, creating a vertically integrated company that designs, builds, launches and operates its own constellations – a direct structural answer to SpaceX and Starlink. The stock jumped about 12% on the news. And yet, a week later, it was among the hardest hit in the pullback. A company does not become strategically weaker in seven days; the tape simply turned.

The Iridium deal is also a reminder that strategy and stock price run on different clocks. The acquisition is not expected to close until mid-2027, and it will take years for the vertically integrated model – launch, manufacture, operate, connect – to prove itself commercially; part of the consideration is stock, which is itself a form of dilution to weigh. A market focused on this week’s tape will discount none of that in either direction. That gap between a multi-year strategic thesis and a one-week price move is precisely where sentiment-driven volatility lives.

07Why these stocks move so violently

Underneath every one of these swings is the same structural feature: these are largely pre-profit companies. Most have little or no trailing earnings to anchor a valuation, so their prices are set by backlog, by expected future contracts, by news flow and by sentiment. When there is no earnings multiple to fall back on, the stock has no natural floor to return to – it floats on belief. That is wonderful on the way up and unforgiving on the way down.

Add thin liquidity for the smaller names – Planet Labs, Intuitive Machines, Satellogic, Redwire and similar – and a heavy retail ownership base, and you get amplification in both directions. A modest shift in flows moves the price more than the underlying news would justify. This is why the sector can be up 25% one week and down 7% the next without the companies themselves changing at all.

08The structural backdrop: the story is not over

None of this means the space economy thesis has broken. The forces that drove the multi-year run are still there: falling launch costs, a wave of government and defence spending on space-based capabilities, the build-out of low-Earth-orbit constellations for connectivity and Earth observation, and a genuine commercial market forming around data, communications and national security. SpaceX’s own numbers – Starlink past 10 million customers and $11.4 billion in annual revenue – are the clearest proof that the demand is real, not a story.

What has changed is the price of admission and the composition of the field. With a $2 trillion incumbent now public, investors will increasingly be asked to distinguish between companies with real, funded, differentiated positions – a launch and satcom champion like the Rocket Lab-Iridium combination, or a genuinely novel connectivity bet like AST – and companies that were mostly a way to own the theme. The maturation of a sector usually looks exactly like this: the easy, everything-rises phase gives way to selection.

The demand underneath is not only commercial. Governments are pouring money into space-based capabilities – communications, Earth observation, missile-warning and layered defence architectures – and that spending tends to be multi-year and contract-based rather than sentiment-driven. It is the part of the space story least visible in a weekly price chart and most important to the multi-year thesis, and it is exactly why the leaders with real government backlogs are structurally different from the names that were mostly a way to own the theme.

09The rest of the basket: what each name really is

Beyond Rocket Lab and Planet Labs, the pullback swept up a cluster of smaller names, and it is worth separating what each one actually is, because ‘the space sector’ is not one trade. AST SpaceMobile is a bet on direct-to-cell connectivity from space – ordinary phones talking to satellites without special hardware – a genuinely differentiated and capital-intensive story that had run about 30% in a week and simply gave part of it back. Intuitive Machines is a lunar-and-space-services play tied to NASA and government programmes, more milestone-driven and binary than the others: it moves on mission outcomes and contract awards.

Satellogic and Redwire sit further down the liquidity ladder: high-beta, thinly traded Earth-observation and space-infrastructure names that tend to move with the leaders’ sentiment rather than on their own news. When Rocket Lab and AST turn, these get carried along with amplified swings, up and down, precisely because a small change in flows moves an illiquid stock more than the underlying news would justify. That is not a flaw to be judged; it is a structural fact to be respected when reading their charts.

The practical takeaway is that a direct-to-cell operator, a lunar-services contractor, an Earth-imaging data company and a launch-plus-satcom champion have very different revenue models, funding needs and catalysts. Treating them as a single ‘space’ basket is convenient for a headline and misleading for analysis. The reset this week hit them together, but the recovery – if it comes – will not be uniform: it will favour the names with funded, differentiated positions over the ones that were mostly a vehicle for the theme.

10A parallel worth remembering: the 2021 space-SPAC wave

For anyone who watched the last cycle, this week carries an echo. In 2020 and 2021 a wave of space companies came public through SPACs at rich valuations on the promise of the space economy; when sentiment turned in 2022, many fell 70-90% as the market repriced pre-revenue promises against reality. It was a painful lesson in what happens when narrative outruns cash flow, and it left a generation of investors wary of the word ‘space’.

But the parallel is a warning, not a template. The 2026 cohort is, on average, further along: real revenue, real backlogs, government contracts, and – in Rocket Lab’s case – an operating launch business and an $8 billion strategic acquisition. This is a more mature version of the same enthusiasm, which is why a pullback here looks more like a valuation reset than the start of a collapse. The risk is not that the theme is fake; it is that even a real theme can be overpriced for a while, and that the market periodically forces that question.

There is one more difference between the two eras: the presence of an anchor. In 2021 there was no dominant public pure-play to benchmark against, so valuations floated on imagination. Today there is a roughly $2 trillion one. That anchor cuts both ways – it validates the sector’s scale and seriousness, while simultaneously drawing capital toward itself and away from the smaller names. A more grown-up market is also a more discriminating one.

11Flows, retail and the shape of the selloff

The mechanics of who owns these stocks explain the shape of the move. A large share of the float in the smaller space names sits with retail investors and momentum funds rather than long-term institutions. That ownership base is fast-moving: it chases strength and exits weakness quickly, which is why the same names can print double-digit weekly gains and then sharp reversals. It is not irrational – it is simply a different kind of holder, with a shorter horizon and a lower tolerance for a stalled chart.

SpaceX’s IPO added a twist here too. By steering roughly 30% of a record-breaking offering to retail, it gave individual investors a direct, headline-grabbing way to own space – potentially pulling some of the same retail attention and capital that had been spread across the proxies. When the marginal buyer of a thin stock steps away, the price does not need bad news to fall; it just needs the bid to thin out. Much of this week looks like exactly that: not selling into fear, but a quiet withdrawal of the marginal buyer.

12How do you even value a pre-profit space name?

If earnings multiples do not work, what does? For pre-profit space companies, analysts lean on a handful of imperfect tools. Backlog – the value of signed but not-yet-delivered contracts – is the most cited, because it hints at future revenue; Rocket Lab’s backlog above $2 billion is a genuine anchor. But backlog is a promise, not cash: what matters is the pace at which it converts into recognised revenue, and at what margin. A large backlog that converts slowly, or at thin margins, flatters the headline more than the business.

The other levers are the path to profitability and the funding gap. A space company burning cash to build constellations or factories must eventually reach breakeven before its balance sheet – or its shareholders, through dilution – runs out of patience. That is exactly the fault line Planet Labs exposed: guiding to breakeven-at-best EBITDA while announcing a $1.5 billion equity programme told the market the funding gap would be filled partly by issuing shares. Price-to-sales multiples fill the rest of the gap, but they are blunt: they say nothing about whether that revenue will ever be profitable.

This is why the sector trades on sentiment: the honest valuation range for most of these names is wide, and a wide range is another way of saying the market does not really know. In that vacuum, momentum, flows and narrative fill the price. It also explains why a piece of hard news – a contract, a launch, an acquisition like Iridium – can re-rate a stock so sharply: it narrows the range by replacing a guess with a fact.

13The European angle

For a European reader, the space story has an extra layer. Almost all the listed pure-plays that move on these headlines are U.S.-listed – Rocket Lab, AST SpaceMobile, Planet Labs, Intuitive Machines, and now SpaceX itself – so a European investor is taking on U.S. equity, U.S. sentiment and dollar exposure when following the theme. Europe has its own space champions in launch and defence, but the tradeable, high-beta ‘space economy’ basket that moved this week is overwhelmingly American.

That matters for two reasons. First, the dollar: a European holding U.S. space names sees returns filtered through the euro-dollar exchange rate, which can add or subtract from performance independently of the stocks themselves. Second, the strategic backdrop is increasingly a European theme too – the continent is raising defence and space spending and debating its own sovereign capabilities in launch, connectivity and Earth observation. The listed vehicles may be American, but the demand story is global, and Europe is now part of the buy side.

14How to read a sector reset without overreacting

When a whole sector falls together, the useful reflex is not to guess the bottom but to sort the causes. Three questions do most of the work. First: is there real bad news, or did the price simply run too far? A broad move with no confirmed catalyst – like most of this week – is a sentiment story, not a fundamentals story. Second: is this a sector move or a single-name move dressed up as one? Planet Labs looked like part of the sector selloff but was really a company-specific guidance-and-dilution event; conflating the two would lead to the wrong conclusion about both.

Third: is the cause reversible or structural? Profit-taking after a run reverses; a scarcity premium unwinding because a $2 trillion competitor went public is more durable and needs time to settle. Separating the fast, reversible causes from the slow, structural ones tells you whether you are looking at noise or at a genuine change in the sector’s centre of gravity. This week has both: reversible profit-taking on top of a structural SpaceX-driven repricing.

The last discipline is to resist the single headline. ‘Space stocks crash’ is a satisfying line and a poor analysis. The names inside that headline sell different things, are funded differently and face different catalysts; some fell on sentiment, one fell on its own guidance, and the strongest of them announced a landmark acquisition days earlier. A sector reset is a moment to tell the companies apart, not to blur them together.

15Two directions for the coming weeks

No forecast – just two plausible paths that the current picture makes possible, with the factors behind each.

Reality will probably sit in between, and it will depend on variables that are not yet settled: the pace of the SpaceX flow, the next earnings and guidance from each name, whether Rocket Lab executes on Neutron and the Iridium integration, and how much fresh government and defence money actually lands. In mid-2026, the most honest word for the sector is ‘selective’.

16Bottom line

This week the space trade cooled, and the temptation is to read a red screen as a verdict on the business. It is not. Rocket Lab announced an $8 billion strategic acquisition and still fell; its CEO’s large sale was scheduled, not a signal; AST gave back part of a 30% weekly gain. The common thread is a re-pricing of scarcity now that SpaceX is public, a sentiment reset after a vertical run, and the structural fragility of pre-profit names with no earnings floor.

The exception is Planet Labs, whose fall has a specific corporate cause – softer guidance and a $1.5 billion equity programme – and deserves to be read on its own terms. For anyone following the sector, the useful lesson is not ‘buy the dip’ or ‘sell the top’; it is that the easy phase is ending, and from here the space economy will reward telling the companies apart far more than owning the theme.

17Frequently asked questions

Did the space stocks fall on bad news?

For most of them, no. There was no confirmed stock-specific bad catalyst behind the broad move; it was profit-taking after a large run, plus capital rotating toward SpaceX now that it is public. Planet Labs is the exception – it fell on its own weak guidance and a large equity offering.

Does the SpaceX IPO really hurt Rocket Lab and AST?

Indirectly, yes. For years those names were proxies for a private SpaceX and carried a scarcity premium. Now that a roughly $2 trillion pure-play is buyable, some capital rotates into the original, compressing that premium. It is a re-pricing of scarcity, not a judgement that the proxies’ businesses got worse.

Is the CEO selling a red flag for Rocket Lab?

The roughly $286 million sale by CEO Peter Beck appears scheduled and pre-planned – a common way to diversify after a stock has run – rather than a statement about prospects. But a very large sale printed while the sector is cooling can still weigh on sentiment in the moment. Intent and market impact are two different things.
