Much of the enthusiasm stems from the expected June 12 debut of Elon Musk’s SpaceX on public markets, an event investors believe could reshape valuations across the broader aerospace sector.
SpaceX IPO Momentum Lifts RKLB, RDW
Institutional investors have increasingly turned to publicly traded aerospace names in search of exposure ahead of the highly anticipated SpaceX listing.
Investors and retail traders view companies such as Rocket Lab and Redwire as alternative ways to participate in the expanding orbital economy before SpaceX shares become widely available.
Rocket Lab stock reached a new all-time high of $146 on Tuesday, gaining for two straight sessions after the company said it completed the acquisition of California-based spacecraft robotics developer Motiv Space Systems, broadening its capabilities in planetary exploration, autonomous systems, and orbital infrastructure.
The acquired business, now renamed Rocket Lab Robotics, is known for designing robotic arms, motion-control technologies, and precision spacecraft components used in several high-profile NASA missions.
Since Rocket Lab already supplies solar technologies to commercial, civil and defense customers, adding robotic and motion-control manufacturing internally strengthens its vertically integrated production model and could reduce dependence on outside suppliers.
Redwire posted one of the strongest moves in the aerospace sector on Tuesday, with shares soaring nearly 26% to close at a fresh 52-week high of $23.10.
Interest surged in Redwire’s potential as a strategic infrastructure provider supporting next-generation space platforms. The company’s Roll-Out Solar Array technology powers spacecraft and satellite systems requiring lightweight yet high-output energy generation.
Story Continues
As expectations grow for future orbital computing networks and larger satellite constellations, demand for efficient solar power systems has also become a major theme across the aerospace industry.
While Rocket Lab gained over 5% overnight on Tuesday, Redwire stock surged over 24%.
The planned public debut of SpaceX is being viewed as a landmark event for global equities, as the company is seeking a valuation between $1.75 trillion and $2 trillion and aims to raise as much as $80 billion.
FTSE Russell, the index division of London Stock Exchange Group plc (LSEG), announced changes on Tuesday to the criteria for inclusion in the Russell U.S. Index Series, introducing a faster pathway for large initial public offerings.
Under the new rules, newly listed companies large enough to pass the Russell Top 500 market value threshold may qualify for faster inclusion in Russell U.S. indexes.
Defense And Satellite Contracts Fuel Buying For SIDU
Sidus Space has emerged as a classic low-float momentum stock. Since early May, shares of Sidus Space have surged from roughly $3.10 to above $6 by May 26, marking a rapid breakout.
The company’s financial performance has also improved. Sidus Space’s fiscal first-quarter revenue surged by 51% from last year while cutting net losses. The company’s involvement in the U.S. Missile Defense Agency’s SHIELD initiative has also raised investors’ sentiment.
Sidus Space stock traded over 11% higher overnight, heading into Wednesday.
PL’s AI-Satellite Move Expands Space Economy Narrative
Planet Labs added to the rally as investors poured into the satellite imaging company following new advances in artificial intelligence processing.
Investors are seeing Planet Labs as a major beneficiary of the expanding market for AI-driven space infrastructure and real-time orbital intelligence. Unlike many space companies primarily focused on launch services, Planet Labs has gained attention for integrating AI directly into its satellite operations.
In March, the company said it is working with Nvidia to deploy Jetson computing modules aboard its Pelican satellite constellation. The onboard systems allow satellites to process imagery in orbit instead of transmitting large amounts of raw data back to Earth for analysis.
Planet Labs’ stock traded over 10% higher overnight, ahead of Wednesday.
So far this year, RKLB, RDW, SIDU and PL stock have gained between 97% to 190%.
