SpaceX plans to launch its Starship V3 on May 20, a single 65-minute test flight that could unlock the largest technology IPO in history and secure the company’s central role in NASA’s lunar ambitions.

SpaceX IPO worth $1.75 trillion hinges on 1 Starship flight
(P1) SpaceX will conduct the first test flight of its Starship V3 on May 20, a launch that serves as a critical gate for its planned $1.75 trillion initial public offering. The success or failure of the 408-foot rocket, the most powerful ever built, will directly inform investor appetite for an offering that could raise between $50 billion and $75 billion as soon as June 12.
(P2) "It’s very hard to care about anything other than the $3 trillion potential IPOs that, in theory, are going to happen in the next year," Sam Lessin, a partner at Slow Ventures, told CNBC, referencing the massive market anticipation for SpaceX, OpenAI, and Anthropic.
(P3) The launch precedes an expected public filing of SpaceX's IPO prospectus as early as the next day. The proposed valuation dwarfs recent blockbuster listings, including AI chipmaker Cerebras Systems, which raised $5.55 billion in May. A successful flight would validate the technological leap of Starship V3, which boasts a 100-ton payload capacity, full reusability, and systems for orbital refueling.
(P4) At stake is not only the largest IPO in history but also SpaceX’s multi-billion dollar contract with NASA to use Starship as the landing vehicle for the Artemis III and IV moon missions. A failure could delay the IPO, complicate its role in the Artemis program, and give a critical opening to competitors like Jeff Bezos's Blue Origin.
A 3x Leap in Capability
The Starship V3 represents a generational upgrade over its predecessor. The rocket’s Super Heavy booster, powered by 33 Raptor 3 engines, generates approximately 18 million pounds of thrust, enabling a near 3x increase in payload capacity from 35 tons to over 100 tons. This leap significantly reduces the cost per pound to orbit and the number of launches required for large-scale satellite deployments or building lunar bases.
SpaceX has also engineered the V3 for rapid reusability. The design includes an integrated hot-staging system, which reduces component loss during stage separation, and larger, stronger grid fins to improve the booster's landing accuracy. For this flight, the booster will attempt a soft splashdown in the Gulf of Mexico, while the upper stage is expected to land in the Indian Ocean after a 65-minute flight.
The Artemis Imperative
Perhaps the most critical new system is the one for orbital refueling. Starship V3 is the first version equipped with docking ports and propellant transfer systems designed to move cryogenic fuels between two ships in low-Earth orbit. This capability, never before demonstrated at this scale, is a mandatory requirement for NASA’s Artemis program, which plans to use a Starship variant to land astronauts on the moon, a mission currently scheduled for late 2027.
The test flight will be closely watched by NASA, which has seen its Artemis timelines slip. A successful demonstration of Starship’s core flight systems is the first step toward validating the complex refueling and docking maneuvers required to send humans back to the lunar surface. The IPO prospectus, potentially coming just hours after the flight, will give investors their first official look at the financials underpinning one of the world's most ambitious technology companies.
