Shares of leading space stocks are pulling back sharply on Monday, with the sector’s top performers giving up a significant portion of last week’s outsized gains.
Rocket Lab (NASDAQ: RKLB) is leading the decline, falling 7% to $93.28 as traders move to lock in profits after a blistering stretch of momentum-driven buying.
AST SpaceMobile (NASDAQ: ASTS) shares are down 5% to $80.61, while SpaceX (NASDAQ: SPCX) stock is off 3% to $157.43, and Intuitive Machines (NASDAQ: LUNR) shares are also 3% lower at $18.93.
There is no confirmed stock-specific catalyst behind Monday’s broad selloff, with the move appearing to reflect profit-taking concentrated in the sector’s highest-beta names.
Rocket Lab stock had climbed 25% in the week ending July 2, while AST SpaceMobile shares surged 30% over the same period, making a pullback of this kind entirely predictable given the pace of gains.
Retail sentiment also signaled a turning point, with a WallStreetBets post titled “RKLB 2900->29k” celebrating gains on July 2, a pattern widely viewed as a classic exit signal among active traders.
Polymarket’s daily direction market is currently pricing a 95% probability that Rocket Lab stock closes lower on the day, reflecting broad expectations that the selling pressure will persist into the close.
These are largely pre-profit, speculative names with no meaningful trailing earnings multiples to anchor valuation, meaning their prices trade on backlog, sentiment, and news flow, which cuts both ways.
The broader bull case for the space sector remains intact, with the commercial-space backlog recently crossing $500 billion and SpaceX’s NASDAQ debut on June 29 giving public investors direct access to the sector’s dominant player.
The U.S. FY2027 space budget totals $59.7 billion and funds 31 launches, a significant step-change from prior years that underpins revenue visibility for companies across the sector.
Rocket Lab’s $2.2 billion backlog and Intuitive Machines’ 2026 revenue guidance of $900 million to $1 billion both lean heavily on that government spending trajectory for near-term growth.
AST SpaceMobile has reaffirmed 2026 revenue guidance of $150 million to $200 million and is targeting approximately 45 BlueBird satellites in orbit by year-end, with constellation execution remaining the key swing factor.
Investors seeking diversified sector exposure without single-name risk can look to the Procure Space ETF (NASDAQ: UFO), a pure revenue-weighted vehicle that includes Planet Labs at 6% and Rocket Lab at 5% among its top holdings.
Traders are watching for updates on Rocket Lab’s Neutron rocket debut, AST SpaceMobile’s BlueBird launch cadence, and NASA CLPS award decisions for Intuitive Machines as the next potential catalysts for the group.
Polymarket’s week-of-July-6 market clusters Rocket Lab stock at $88 to $92, suggesting the crowd anticipates stabilization rather than a deeper, more sustained flush lower.
