From the SPAC craze to traditional IPOs—why is SpaceX accelerating its listing now?

The SpaceX IPO rumors have drawn massive attention this time, not only because of its $1.75 trillion valuation, but also because they signal a fundamental shift in Musk’s attitude toward capital markets. Over the past decade, he has repeatedly emphasized that “going public is a constraint,” but now Starlink needs to keep burning cash, Starship requires massive funding, and financing in the primary market has nearly hit its limit. So when will this IPO land at the earliest? Is June 12 really feasible?

To answer this question, let’s first look at the details of the IPO route SpaceX has chosen. According to reports, SpaceX plans to use a traditional IPO approach rather than a SPAC. A traditional IPO requires the following steps: confidential submission of the S-1 → the SEC’s first round of feedback → public submission of the S-1 → roadshow → pricing → listing. At the moment, there is no sign of a publicly filed S-1, suggesting SpaceX may still be in the confidential submission stage—or may not have submitted yet at all. The benefit of confidential submission is that it allows for early communication with the SEC, but even so, it usually takes 4-6 weeks to go from confidential submission to public filing. Assuming confidential submission on May 1, the public filing could be in early June, with roadshows in mid-to-late June, and the earliest listing could be no earlier than late June or early July.

In addition, SpaceX’s financial complexity is far beyond that of ordinary companies. It involves government contracts (NASA, the Department of Defense), the Starlink consumer business, Starship R&D investments, and more. The SEC will be even more cautious when reviewing this kind of “new economy + military-industrial” hybrid. Citing the Palantir listing process as a reference, it took nearly 3 months from confidential submission to listing. Therefore, the claim about June 12 seems more like the underwriters’ tentative trial balloon with the media, with the goal of testing market sentiment.

There is another key variable: Musk’s own lawsuits and his attention. He is simultaneously busy with Tesla, xAI, Neuralink, and integrating after the acquisition of X. An IPO requires the CEO to spend a large amount of time on roadshows and answering questions from analysts. Is Musk willing to set aside a week in mid-June to do roadshows? I think he is more likely to choose July or August, because by then Tesla’s Q2 deliveries have already passed, the earnings report has not yet been released, and he should have relatively more time.

From an investor’s perspective, a $1.75 trillion valuation requires strong subscription demand. The US IPO market has just started to warm up, and cases like Arm and Instacart show that mega-IPOs need at least a two-month ramp-up period. While SpaceX has its halo, it can’t be an exception. Putting all of the above together, I believe the earliest IPO is most likely in late July 2026 to early August. June 12 is almost impossible—unless Musk pulls off another “Twitter IPO” stunt.

On Polymarket, I recommend focusing on the “July” and “August” options. If the odds for “June 12” are extremely high (for example, more than 10x), then a small bet for entertainment is fine, but the main position should be placed in a more realistic time window. Remember: what prediction markets compete on isn’t who is more optimistic, but who assesses the process more calmly.

My conclusion: the earliest IPO time is after July 20, and the probability of June 12 is below 5%.
