No pressure, SpaceX, but your blockbuster IPO could reshape the market as we know it

• SpaceX has filed to go public, and its IPO is expected in the next couple of months.
• The size and influence of the offering will be nearly unrivaled in the history of markets.
• Detailed below are three ways a SpaceX IPO could reshape markets as we know them.

Did you hear about the trend in markets that was red-hot until the Iran war came and threw cold water on it?

I could be talking about any number of things. But, in honor of SpaceX's recent filing to go public, I'm speaking specifically today about the IPO market.

On the surface, 2026 has started strong enough. The $24 billion in proceeds raised by IPOs in the first quarter is nearly double the same period in 2025. But after the start of the Iran war in late February, the IPO count and total capital raised were cut in half in March, Bloomberg data shows.

The fact that SpaceX is forging ahead with an offering during macro instability tells you how confident CEO Elon Musk is in the company's public-market prospects.

And, despite its immense size (the latest reports say SpaceX is seeking a valuation north of $2 trillion), the offering itself will pale in comparison to the wide-reaching impact it has on the IPO market and other companies overall.

Here are three major considerations as SpaceX prepared to reshape public markets:

1. It could reset valuations across the space economy

SpaceX going public is expected to add legitimacy to an industry that was previously treated as a high-risk frontier investment.

A re-rating of space stocks has already started occurring across multiple subsectors. Rocket Lab, the purest comp for SpaceX, is up 7% since reports of the IPO filing.

Other launch-adjacent names like Firefly Aerospace and Intuitive Machines have seen even bigger gains of roughly 25%, while satellite providers like Planet Labs and Viasat are up double-digit percentages over the period.

2. It could supercharge concentration risk in major indexes

One controversial development associated with the SpaceX IPO has been Nasdaq's proposed "fast entry" rule. Basically, Nasdaq wants SpaceX to be in the tech-heavy Nasdaq 100 index as soon as possible, so they're considering shortening the inclusion timeline from three months to 15 days.

While this would hasten the ability of everyday investors to buy exposure to SpaceX, it also could ramp up concentration risk. The argument goes: If a few market-cap titans can dictate the direction of a whole index, that's too much power, and leaves the gauge vulnerable. It's a dynamic investors have contended with for years amid the rise of the Magnificent 7.

3. It will set the tone for mega-IPOs to come

As SpaceX prepares for its public debut, other private juggernauts like OpenAI and Anthropic will be watching closely. How SpaceX fares could ultimately determine when they file to go public, how much they'll aim to raise, which banks they hire, and which exchange they list on.

The market and its assorted dynamics could feel very different once the holy trinity of private tech unicorns is fully public. Stay tuned for more updates on SpaceX's maiden voyage.
