Space stocks, including Redwire (RDW), AST SpaceMobile (ASTS), and Momentus (MNTS), are ripping higher this morning in anticipation of SpaceX’s blockbuster IPO on June 12th.
Yet, institutional and retail investors are actually treating these three names quite differently based on the specific nuances of the behemoth’s S-1 filing.
SpaceX IPO isn’t just a generic headline; it contains specific business segments – launch services (Falcon/Starship), satellite hardware/component manufacturing, and satellite broadband (Starlink).
And each of the three stocks: RDW, ASTS, and MNTS maps to a different one of these segments, catching a unique fundamental tailwind from the S-1 disclosures.
Momentus stock: launch-sympathy and micro-cap beta play
Momentus is a space infrastructure company specializing in “last-mile” satellite delivery via its Vigoride orbital transfer vehicles.
On Tuesday, it’s catching the tailwinds of the Starship/Heavy Launch portion of the SpaceX filing, which highlights a massive, aggressive scaling of the Falcon 9 and Starship launch cadence.
More rocket launches mean more rideshare slots, which directly increases the addressable market for a company like Momentus that helps smaller satellites maneuver into custom, precise orbits once dropped off by the main rocket.
With a market cap hovering around $100 million, MNTS shares are a classic high-beta, thin-float vehicle.
When a macro thematic wave hits, retail and momentum traders often flood into the smallest, most volatile stock in the sector to maximize percentage gains.
Redwire stock: the component supply-chain benchmark
Redwire is an aerospace prime contractor that manufactures highly technical hardware – like solar arrays, docking mechanisms, and space-qualified 3D printers – mapping directly to the aerospace manufacturing multiples revealed in SpaceX’s S-1.
To justify an unprecedented $1.75 trillion IPO valuation, the SpaceX prospectus leaned heavily on the immense capital value of its industrial manufacturing, component supply chain, and government defense pipelines.
On Tuesday, investors are looking at RDW shares and realizing they are a direct public proxy for high-margin aerospace manufacturing.
Redwire’s strong Q1 metrics ($97 million in revenue, up nearly 58% year-over-year, and a record $498 million backlog) are attractive to funds that can’t buy SpaceX shares until June, as it trades at a huge discount to the luxury multiple Musk’s company has established for space hardware.
AST SpaceMobile stock: the Starlink direct-to-call validation
AST SpaceMobile is building a space-based cellular broadband network. It is rallying because of disclosures surrounding Starlink and its direct-to-cellular ambitions.
The S-1 filing highlights Starlink’s commercial traction and its plans to expand its “Direct to Cell” capabilities globally.
Instead of fearing this competition, investors are reading it as the “ultimate” proof-of-concept.
SpaceX’s filing proves that direct-to-device satellite telecom is a multi-trillion-dollar vertical – not science fiction.
ASTS shares are charging higher because the company has already locked down a domestic carrier alliance (AT&T, Verizon, T-Mobile) and formal FCC commercial approval.
It, therefore, stands as the primary, fully-funded public competitor to Starlink.
