SpaceX Prepares for Historic Starship Version 3 Test Flight After IPO Filing

A Make-or-Break Moment for SpaceX

SpaceX scrubbed its attempt to launch the 12th test flight of its Starship megarocket Thursday evening, after last-minute issues triggered a series of holds. The earliest SpaceX can attempt another launch is tomorrow evening at 6:15 p.m. ET, according to federal air traffic warnings. The mission, the Starship program's first in months, will mark the much-anticipated debut of an upgraded version of the vehicle, called Version 3 or V3. This test comes at a critical juncture for the company, which just filed for what would become the largest IPO in history.

The company is headed for a record-shattering initial public offering, and explosive, attention-grabbing mishaps, such as the kind that have resulted from previous Starship test flights, tend to make investors squeamish. There "are likely more eyes on this test launch than ever before for this company," noted Andrew Chanin, the CEO of the investment firm ProcureAM. The timing couldn't be more precarious—or more deliberate.

During two separate test flights in January and March, the vehicle exploded near populated areas east of Florida, creating debris that hit roadways in Turks and Caicos and washed up onto Bahamian islands. On another test flight in May 2025, the launch system performed notably better, but the Starship spacecraft ultimately spun out of control as it descended toward its landing site in the Indian Ocean.

Version 3 Brings Major Upgrades

The new launch vehicle stands slightly taller than the last model, for example, and both the Super Heavy booster and Starship spacecraft, often simply called "ship," are equipped with a new generation of Raptor rocket engines that pack a considerably heftier punch than their predecessors. Each of Super Heavy's 33 engines, for example, will deliver more than 50,000 additional pounds of force at liftoff, according to SpaceX. The company says the engines are also lighter, which should give them better efficiency and increased umph.

Ship 39 will deploy 22 Starlink simulators, similar in size to next-generation Starlink satellites, into the same suborbital trajectory as the Ship itself. The last two satellites deployed will scan Starship's heat shield and transmit imagery down to operators to test methods of analyzing Starship's heat shield readiness for return to launch site on future missions. As this is the first flight test of a significantly redesigned vehicle, the booster will not attempt a return to the launch site for catch.

Starship could be the lunar taxi used in NASA's Artemis 4 mission, which would see astronauts "travel to lunar orbit, where two crew members will descend to the surface and spend approximately a week near the South Pole of the Moon conducting new science before returning to lunar orbit to join their crew for the journey back to Earth," according to NASA. The agency aims to launch the mission in 2028.

The Trillion-Dollar Stakes

On May 20, 2026, Elon Musk filed paperwork to take one company public at $1.75 trillion, seventy times that cost, under a single stock ticker. SpaceX's IPO isn't just the biggest in history. It's the first time a public market has been asked to price a rocket company, a satellite internet empire, an AI lab, and a social network; all controlled by one person, all wrapped inside one filing.

The company targets a $1.75 trillion valuation with a planned $75 billion capital raise, which would set the all-time record for IPO fundraising. Nasdaq listing is scheduled for June 12, 2026, following pricing on June 11. At a $1.75 trillion IPO valuation, his ~42% equity stake alone is worth approximately $735 billion. Add his Tesla holdings and he crosses the trillion-dollar mark.

With less than 7% of the $1.75 trillion implied valuation backed by current profit, June 11 pricing becomes a referendum on Starship execution, AI-segment capital intensity, and a controlled-company governance structure at trillion-dollar scale. The success or failure of tomorrow's test flight could significantly impact investor confidence just weeks before the historic public offering.

What's Next for Space Commerce

The SEC filing explicitly states that SpaceX expects Starship to begin commercial payload delivery to orbit in the second half of 2026. This represents a compressed timeline with minimal margin for test failures. Starship's success is critical to SpaceX's long-term value proposition, as it promises to dramatically reduce launch costs and enable ambitious missions including lunar supply runs and eventual Mars transportation.

The test flight represents more than just another milestone in SpaceX's development program. It's a proving ground for technologies that could reshape how humanity accesses space, from routine satellite deployment to eventual Mars colonization. SpaceX's public debut will likely catalyze a secondary wave of
