SpaceX’s Record 74-Day IPO: Can OpenAI and Anthropic Replicate SpaceX’s Capital Miracle?

TradingKey - When the U.S. Securities and Exchange Commission (SEC) demonstrated an unprecedented review speed for SpaceX's (SPCX) IPO application.

The space exploration company founded by Elon Musk took just 74 days from confidentially filing its prospectus to its official listing, compressing the average cycle of recent major tech IPOs by more than one-third.

This record-breaking speed not only shattered the market's perception of the traditional IPO process but also provided a clear timeline reference for OpenAI and Anthropic, which have similarly filed confidentially.

SpaceX's IPO process was divided into two key phases: taking just 51 days from the confidential submission of its draft to the public disclosure of its prospectus, compared with the 70 to 95 days that previous major tech IPOs like Snowflake and Airbnb spent in this phase.

Furthermore, from the public disclosure of the prospectus to the official listing, SpaceX took only 23 days, setting a record as the fastest major tech IPO in recent years.

Data from law firm Latham & Watkins shows that the entire IPO process typically takes 117 days, whereas SpaceX compressed this timeline to 74 days, saving approximately 37% of the time.

Regulatory Shift and Demand-Driven Push

Several capital markets attorneys noted that the SEC's current review of disclosures has become noticeably more relaxed, with regulators more inclined to push large, well-known companies to complete their listings as quickly as possible.

Mike Blankenship, co-chair of the capital markets practice at law firm Winston Taylor, said: "This administration is moving much faster on SEC comment letters and genuinely wants to promote more capital formation, so they are not digging into the details of certain disclosures."

Notably, SpaceX's filing itself is not simple. The company completed its acquisition of Musk's xAI in February this year, turning it from a profitable enterprise into a heavily loss-making one. Three weeks after the confidential filing, SpaceX signed an option agreement to acquire AI programming startup Cursor for $60 billion.

During the roadshow, the company also signed multi-billion-dollar cloud computing contracts with Anthropic and Google, respectively. Furthermore, the company carries a heavy debt load, numerous related-party transactions, and a corporate governance structure heavily skewed toward Musk—factors that would typically trigger more scrutiny from regulators and investors in the past.

SpaceX's rapid path to listing is also inextricably linked to its strong market demand. The company already commands over 80% of the global rocket launch market, with more than 10,000 Starlink satellites in orbit, over 10 million global users, and 2025 revenue already surpassing $10 billion. The merger with xAI has further injected a new growth narrative of 'AI + space computing' into the company, which plans to use Starship to deploy orbital data centers.

The Front-Running Rivalry Between OpenAI and Anthropic

For OpenAI and Anthropic, the speed of SpaceX's listing provides an important benchmark. Both companies have already confidentially filed for an IPO. If the SEC maintains a review pace similar to its audit of SpaceX, their prospectuses could be publicly disclosed as early as mid-to-late July, followed by about three weeks to complete roadshows and officially list, meaning both companies are expected to debut on the capital markets by mid-August.

However, even if they are technically ready to list by mid-August, both companies may voluntarily delay their timelines slightly to avoid the summer holiday season for investors.

Capital markets attorney Julian Perlmutter explained that there is a clear commercial driver behind the accelerated IPO: "Your investors have billions of dollars in cash ready to put into your IPO. You need to get the deal done when they are ready."

He also pointed out that the longer the process drags on, the more time skeptics have to pick apart the company's narrative. For OpenAI and Anthropic, this logic applies equally. Both companies are seeking large-scale funding; if the listing process is delayed, large institutional investors may redirect their allocated capital elsewhere.

However, the SpaceX case also serves as a reminder to AI companies that a rapid listing does not mean risks can be ignored. SpaceX proved that hot mega-cap tech companies can compress the IPO timeline, but public markets do not reward speed alone. If AI companies also want to accelerate their listings, they must address losses, capital expenditures, related-party transactions, computing power contracts, and governance structures earlier, rather than just telling a growth story.

Currently, the SEC's specific comments on SpaceX's filing have not been made public; relevant correspondence is typically disclosed through the regulator's website about a month after the IPO is completed.

The real challenge facing OpenAI and Anthropic is not just how to accelerate the listing process, but more importantly, how to clearly demonstrate their long-term growth potential and sustainable business models to the market while listing rapidly.
