SpaceX is about to test a heavily redesigned Starship at a crucial moment — just weeks before investors expect the company to go public. The flight will use dozens of new Raptor 3 engines and a revised booster fuel system, carry upgraded avionics and satellites, and include test fittings for an in-orbit refueling scheme that aims to extend Starship’s reach to the Moon and beyond.
The timing matters because the company’s upcoming initial public offering could raise tens of billions of dollars and place a valuation on SpaceX well into the hundreds of billions or more. Analysts have suggested the IPO could fetch as much as $75 billion and imply valuations approaching $1.5 trillion. For many observers, how Starship performs on this flight will be a visible demonstration of whether that future is plausible.
PitchBook researcher Franco Granda says the launch is especially important for the IPO. If the flight fails, he warns, investor enthusiasm could fade quickly. SpaceX itself has signaled the same stakes in recent financial disclosures: the company is investing billions annually in Starship development, and those costs are eating into the profits of its existing launch business. In the first quarter of 2026 the launch unit operated at a loss of roughly $662 million. SpaceX spent just over $3 billion on Starship in 2025 and another $930 million in Q1 2026.
Starship is unlike any rocket flown before. About 400 feet tall and built from stainless steel, the system pairs a massive Super Heavy booster — packed with dozens of Raptor engines — with the Starship spacecraft on top. After stage separation the booster is intended to return and land at the launch site, while Starship carries on using its own engines. Elon Musk has repeatedly said the goal is near-instantaneous reusability of the entire stack to slash launch costs.
Lower costs and much higher payload capacity are central to SpaceX’s strategy. Starship would let the company loft larger, more capable satellites for Starlink, serve as the lunar lander NASA contracted for Artemis missions, and eventually support Mars missions. Musk has also floated more speculative concepts, such as placing data centers in orbit powered by solar arrays to run energy-hungry AI chips.
Industry observers caution that success is far from guaranteed. The very first Starship launch in April 2023 failed to separate cleanly from its booster and ended in an uncontrolled breakup. It took several more attempts before the vehicle achieved a proper ascent to space. Iterations in 2025 saw multiple setbacks before the most recent flights performed as intended.
This third, heavily revised version incorporates many design changes: heat shield tiles appear more systematically installed, temporary field modifications have been folded into the engineering, and the new Raptor 3 engines are meant to deliver higher thrust while removing the need for heavy protective structures beneath the booster. Scott Manley, an engineer and longtime Starship analyst, says those updates make the vehicle look more refined, but notes the Raptor 3s, while extensively ground-tested, have not yet experienced flight conditions and their in-flight behavior remains uncertain.
Even a smooth demonstration flight will not resolve all questions. Key technologies still need proof of repeatable performance: the heat shield must survive multiple reentries, precision landings at the Texas pad must be achieved, and the full suite of reusability, turnaround cadence and operational reliability has yet to be demonstrated at scale. Tim Farrar, a satellite services analyst, says Starship presents a far more complex engineering and operational challenge than the company’s workhorse Falcon 9. Meeting those challenges is essential if investors are to justify the loftier valuations that hinge on Starship enabling much larger markets.
SpaceX’s financial filings bluntly acknowledge the risk: delays or failures in achieving required launch cadence, reusability and capabilities would slow or limit the company’s growth plans. For now, the upcoming flight is a high-profile test of engineering and of investor confidence. A successful mission would mark another step toward the ambitious vision SpaceX has outlined; a setback would underscore how much work remains before Starship becomes the dependable backbone of the company’s future.
