As SpaceX gears up for a crucial test of its largest rocket, Starship, the outcome could significantly impact its impending initial public offering (IPO). Scheduled for launch from Starbase, Texas, on Thursday, the redesigned version of Starship is equipped with dozens of new Raptor 3 engines and a novel fuel system. This 400-foot rocket will also feature upgraded avionics, satellites, and ports for future refueling systems, paving the way for missions to the Moon and Mars.
Analysts predict that SpaceX’s IPO could raise as much as $75 billion, potentially valuing the company at $1.5 trillion, making it one of the largest IPOs in history. However, the success of the upcoming launch is seen as pivotal for garnering investor confidence. Senior researcher Franco Granda from PitchBook noted that if Starship’s test fly experiences significant issues, the enthusiasm surrounding the IPO may wane.
Financial disclosures highlight the importance of this test. SpaceX has invested billions annually into Starship development, which has contributed to losses in its launch business—recording a loss of $662 million in the first quarter of this year. The Starship system, unlike any other rocket built to date, operates by utilizing an enormous booster named “Super Heavy,” which powers the launch with 33 Raptor engines. After separation, Starship can ignite its own engines for a continued ascent, while Super Heavy is designed to return and land at the launch site, contributing to a reusability model aimed at lowering overall launch costs.
Elon Musk has emphasized the critical nature of Starship for SpaceX’s long-term goals, including launching larger satellites for the Starlink internet service and serving as a lunar lander for NASA. Recently, Musk proposed using Starship to deploy data centers capable of harnessing solar power for AI operations in space.
The implications outlined in SpaceX’s financial documents reveal that any significant delays or failures in Starship’s development could restrain the company’s growth trajectory. In 2025, SpaceX’s investment in Starship exceeded $3 billion, with an additional $930 million spent in early 2026.
The latest iteration of the rocket is characterized by enhancements like improved heat tiles and integrated design changes intended to facilitate more reliable operation. Yet, despite these advancements, questions remain about the new Raptor 3 engines, which, while tested on the ground, have yet to prove themselves in actual flight.
Starship’s journey to reliable operations has been fraught with challenges. The previous version launched in April 2023 succumbed to failure before ultimately reaching space after three attempts. The subsequent version dealt with multiple setbacks, although its final launches performed successfully. Compared to earlier models, the newest version appears more streamlined and refined, suggesting a step forward in design philosophy.
However, as some experts caution, achieving a successful operational business model with Starship will entail overcoming substantial hurdles. Issues surrounding the heat shield’s durability, landing capabilities, and complex operational requirements stand as significant obstacles. Industry analysts stress that a valuation upward of a trillion dollars necessitates a strong belief in Musk’s ability to propel SpaceX to new heights well beyond its current capabilities.
