Firefly Aerospace Inc. shares closed 15.5% higher at $49.50 on Friday and ended the week up about 22%, as investors bought publicly traded space names after fresh SpaceX news pulled attention back to the sector. The move came on heavy volume for FLY and put the stock above its August IPO price.
The timing matters. U.S. markets are shut for the weekend and Nasdaq is closed Monday, May 25, for Memorial Day, leaving Tuesday as the next regular trading session for investors to decide whether Friday’s move was a durable bid or a late-week chase.
SpaceX is not yet a listed peer, but its planned initial public offering — an IPO, or first sale of shares to public investors — has become the sector’s price-discovery event. Reuters reported that SpaceX’s filing targets a possible $1.75 trillion valuation and a listing as early as June 12; Georgetown finance professor Reena Aggarwal called it a Musk “halo effect” and noted the difficulty of valuing a company with no clean peer group.

Friday’s Starship test added to that trade. Reuters reported that SpaceX deployed mock satellites and carried out a controlled splashdown, with Georgetown CSET’s Kathleen Curlee calling the flight “another meaningful step forward,” even as the test still had anomalies. Reuters
Firefly was not alone. Rocket Lab rose 8.2%, AST SpaceMobile gained 10.0% and Virgin Galactic advanced 17.8% on Friday, showing that the bid was broader than one company and tied to space-sector risk appetite.
The read-across was visible overseas too. OHB Chief Executive Marco Fuchs told Reuters that “big IPOs are good for the market,” while ODDO BHF analyst Stéphane Beyazian said investors had appetite for space exposure and potential valuation re-ratings — market shorthand for higher multiples. Reuters
Firefly also had a company-specific hook last week. On May 19, it said a new central Texas campus would double its Cedar Park footprint to 144,000 square feet, with a larger cleanroom — a controlled area used to build sensitive spacecraft hardware — and an innovation lab; Chief Operating Officer Ramon Sanchez said the company was “producing rockets and spacecraft at scale.” Firefly Aerospace
Earlier this month, Firefly reported record first-quarter revenue of $80.9 million, up 40% from the previous quarter, but also a first-quarter net loss of $96.7 million. The company kept full-year 2026 revenue guidance — management’s sales forecast — at $420 million to $450 million, and Chief Executive Jason Kim said “momentum defined Firefly’s first quarter.” Firefly Aerospace
But the risk case is still blunt. A quarterly filing listed delayed or failed launches, spacecraft performance problems, manufacturing shortfalls and the operational risks of space missions as threats to results; if Firefly misses launch cadence or the SpaceX-led sector trade cools, Friday’s rally could thin out quickly.
Investors have seen the stock move sharply since its debut. Firefly priced its IPO at $45 a share and raised $868.3 million last August; PitchBook analyst Ali Javaheri said at the time that responsive launch and a lunar payload were “proof points that matter,” while investors would watch backlog, margins and cash runway.

The scheduled item for the week ahead is Firefly’s appearance at the 5th Annual Virtual Jefferies Space Summit on Tuesday, May 26, at 10:00 a.m. EDT. Its annual meeting is listed for June 4.
Tuesday’s trade may come down to a simpler question: whether Firefly is being priced as a lunar, launch and defense contractor with room to scale, or as another volatile space name caught in SpaceX’s wake.
