In 2026, the commercial space sector continues attracting investor attention, with AST SpaceMobile (ASTS) and Firefly Aerospace (FLY) emerging as two of its most compelling — and volatile — plays.
AST SpaceMobile trades at $51.46 with a market cap of $15 billion and a 52-week range of $47.57 to $133.86, reflecting significant price volatility over the past year.
Firefly Aerospace trades at $19.37 with a market cap of $3.3 billion and a 52-week range of $16.00 to $62.17, offering investors a lower entry point with its own set of risks.
AST SpaceMobile is building a global cellular network designed to connect standard smartphones directly to satellites, a technology with enormous addressable market potential if successfully executed at scale.
Firefly Aerospace takes a different approach, providing launch vehicles, orbital services, and lunar landers to both government and commercial customers, including NASA and the Space Force.
In fiscal year 2025, AST SpaceMobile reported revenue of nearly $71 million, representing roughly 1,500% growth over the prior year, though it also posted a net loss of close to $342 million during the same period.
Firefly Aerospace reported Q2 revenue growth of 659% year over year, while simultaneously reporting a net loss of $92.3 million for the same quarter, underscoring how capital-intensive its operations remain.
Firefly now holds six contracted lunar missions, and its government partnerships with NASA and the Space Force provide a relatively stable pipeline compared to AST SpaceMobile’s more speculative commercial model.
Firefly made history in March 2025 when it became the only private company to execute a successful lunar landing, completing that milestone through its Blue Ghost Mission I.
Valuation differences between the two companies are stark, with AST SpaceMobile carrying a price-to-sales ratio of 149x compared to Firefly Aerospace’s far more modest 12.9x ratio.
AST SpaceMobile’s gross margin stands at a deeply negative 24,279%, while Firefly Aerospace carries a positive gross margin of 16.49%, suggesting Firefly has a more mature path toward near-term profitability.
AST SpaceMobile’s debt-to-equity ratio sits at approximately 1.2x as of its December 2025 balance sheet, reflecting meaningful leverage as the company continues expanding its satellite constellation.
A growing concern for AST SpaceMobile investors is competitive pressure from SpaceX, which is pursuing similar satellite-to-cellular technology with considerably more resources and brand recognition.
CEO Elon Musk’s profile continues drawing investor interest toward SpaceX-adjacent ventures, which may further reduce AST SpaceMobile’s appeal as a standalone investment thesis in the near term.
Firefly does not need to compete with SpaceX across every segment to build a valuable business, since capturing a meaningful share of launch, lunar, and national-security space contracts could prove sufficient for long-term growth.
Both companies burn cash aggressively and carry negative earnings-per-share figures — ASTS at -$2.14 and FLY at -$2.38 — reminding investors that profitability remains a distant target for each.
For investors with high conviction in direct-to-device satellite technology, ASTS offers transformative upside, while FLY suits those seeking more diversified space exposure at a fraction of the valuation premium.
