Firefly Aerospace Inc (NASDAQ:FLY) shares are climbing sharply on Tuesday after last week's successful Starship V3 test flight and the release of SpaceX's massive IPO prospectus.

SpaceX's Starship V3 Test Flight Ignites Sector Momentum

According to the user‑provided details, SpaceX managed to pull off a rough but ultimately successful test of its upgraded Starship V3 on Friday. All 33 Raptor engines fired at liftoff, the vehicle reached space, and it deployed 20 Starlink mass simulators even after losing one of its upper‑stage engines.

Engineers also sent two functional Starlink satellites equipped with flashlights to capture footage of Starship's heat shield during separation, a key step in proving the rocket's reusability.

IPO Prospectus Fuels Broader Space Enthusiasm

The test flight landed just days after SpaceX publicly filed for what could become the largest IPO in history. The company is reportedly seeking up to $75 billion in fresh capital at a valuation that could approach $2 trillion. Prediction markets are treating a June listing as highly likely, with a Nasdaq debut expected around June 12 under the ticker SPCX.

The filing also confirmed that SpaceX's growth plan is "highly dependent on Starship," the same rocket that just completed its V3 test.

Sector Sentiment Lifts Firefly

Prediction markets are even assigning a 21% chance that SpaceX launches a crewed Starship mission to Mars before 2030, underscoring how ambitious the company's long‑term vision is and how much optimism is flowing into the space sector.
