Rocket Lab Corp (NASDAQ:RKLB) shares are trading lower Thursday afternoon, extending a volatile stretch for space-related equities as investors keep rotating out of the group. The pullback comes as the space trade shows renewed weakness and traders reassess financing risk across capital-intensive names.

Space Stocks Extend Weakness

Space stocks ran in 2025, but the sector has hit resistance in 2026 as speculation around a potential SpaceX IPO pulls liquidity toward a “wait-and-see” posture. That repositioning has coincided with broad declines across launch and satellite peers in recent weeks.

Rocket Lab News Adds Company-Specific Pressure

For Rocket Lab, recent volatility has also been tied to a key headline: Congress’ decision to withhold funding for a planned 2031 Mars sample-return mission, an overhang that has pushed investors to recalibrate the company’s longer-term opportunity set.

Meanwhile, Rocket Lab remains in build mode on its reusable Neutron rocket, and sentiment can swing quickly when the market is already de-risking the broader space complex.

Why AST SpaceMobile’s Capital Raise Still Matters For The Group

AST SpaceMobile Inc (NASDAQ:ASTS) late Wednesday announced a major capital raise, pricing $1.0 billion of 2.250% convertible senior notes due 2036 with an initial conversion price of about $116.30 per share (roughly a 20% premium to the prior close) and an option for buyers to purchase up to an additional $150 million of notes. ASTS also disclosed a registered direct offering totaling 6,337,964 shares.

Big financings like this can create an overhang across the space sector: traders worry about dilution if converts turn into shares and about technical pressure from convertible-arbitrage hedging. In a market already treating space names as higher risk, that combination can amplify downside moves in stocks like RKLB.

Rocket Lab Stock’s Volatile Year
