SpaceX IPO Is 4x Oversubscribed, But What Happens to the Rest of Market

Even if you’re not involved with the $SPCX IPO, its massive size is causing market-wide fluctuations that could affect your investments. Many investors might be caught off guard by these changes.

Key Takeaways:
SpaceX drew $250B in IPO demand by June 12, pulling liquidity from crypto and tech markets.
Nasdaq-100 funds may buy $22B-$27B of SpaceX, forcing sales of Nvidia and other holdings.
OpenAI and Anthropic IPOs could follow in 2026, extending volatility and funding pressures.

I have to admit that the topic of SpaceX’s IPO is impossible to avoid at this point of time. The order book closed roughly four times oversubscribed at a $1.75 trillion valuation, which is peak FOMO by any definition. Yet at the same time, risk assets everywhere else have been getting hit. Crypto had one of its ugliest weeks of the year, and megacap tech hasn’t been spared either.

FOMO on one side, bear market on the other. That didn’t make sense to me, so I spent a few days trying to understand this IPO properly. The short answer: the two aren’t in conflict. The selling is what’s funding the FOMO. Once you see how the money moves, the rest of 2026 becomes easier to read, including for the AI-infra and mining names we follow here.

Basics

The basics first. SpaceX (SPCX) will list on Nasdaq June 12, selling shares at a fixed $135 to raise about $75 billion at a $1.75 trillion valuation. That’s more than double Saudi Aramco’s record 2019 raise, and it instantly puts SpaceX among the ten most valuable U.S.-listed companies.

Reported demand reached roughly $250 billion, about four times the shares available. Some institutions put in $10 billion orders on their own. Retail investors also got an unusually large slice: about 30% of the offering through Robinhood, Fidelity, Schwab, SoFi and E*Trade, when big IPOs typically reserve 5-10% for them.

That leads to a question no one discussing the fear of missing out appears to be asking: where did the massive $250 billion in interest for these new company offerings actually originate?

Someone Has to Sell First

People don’t typically hold large sums of money as cash. When investors want to buy something new, they usually sell existing investments, often those that have already increased in value. If thousands of investors do this at the same time for the same opportunity, it can cause money to flow out of other investments.

That’s the bridge between the two moods. Crypto lost over $180 billion in value the same week the order book filled up, and one research desk called it an “IPO tax” on the rest of the market. I’d be careful with that label, since rate-cut doubts and leveraged liquidations were doing damage too. No single deal explains a drawdown that broad. But the basic flow is hard to argue with: when the largest IPO in history closes its books, the cash comes from somewhere, and “somewhere” means whatever investors can sell quickly.

The FOMO and the bear market are the same trade, seen from opposite ends.

Index Funds Become Buyers

What sets this initial public offering apart from other major ones is that some of the purchases aren’t actually choices made by investors – they’re essentially required.

Nasdaq changed its index rules this spring, clearly with SpaceX in mind. A new listing that ranks in the top 40 by market cap can now join the Nasdaq-100 just 15 trading days after its debut. The old three-month waiting period is gone, and the minimum float requirement was scrapped entirely. FTSE Russell loosened its float rules too. Only S&P Dow Jones refused to follow: on June 4, it rejected its own fast-track proposal, which keeps SpaceX out of the S&P 500 until at least mid-2027.

In practice, this means that within about three weeks of listing, every fund tracking the Nasdaq-100 will buy SpaceX. Estimates put that automatic buying at $22-27 billion. And since index funds are always fully invested, they have to sell a little of everything else to make room. Nvidia, Apple, Microsoft, Amazon, and the AI-infra names that have made it into the Nasdaq-100 all get trimmed to fund the purchase of SPCX.

If you own QQQ or a similar fund that follows the Nasdaq index in your retirement account, you’re automatically part of this market situation, even if you didn’t intend to be. Those who invest in S&P 500 funds aren’t affected yet; the need for them to buy more won’t come up until 2027.

Then the Insiders Arrive

As we approach the public trading launch, there’s one key detail to understand: initially, only a very limited number of SpaceX shares – around 3-5% – will be available for trade. Considering that index funds will likely automatically purchase between $22 and $27 billion worth of stock, combined with anticipated activity from other traders trying to get ahead and strong demand from individual investors, this small float is almost guaranteed to create a significant initial price surge.

But supply is coming, and on an unusually fast schedule. Instead of the standard 180-day lockup, SpaceX negotiated a rolling one. Insiders can sell up to 20% of their holdings just two days after the first earnings report, with more unlocking through the fall. Musk and a few major backers accepted a full one-year lockup, but they’re the exception. The early money, investors who waited a decade for this exit, gets their first window within weeks.

As an analyst, I’ve been watching the potential impact of SpaceX becoming a publicly traded company, and it reminds me a lot of what happened with Tesla when it was added to the S&P 500 in December 2020. With Tesla, the stock price surged about 70% leading up to the inclusion, but then it stalled and even declined for weeks afterward as initial buying pressure subsided and investors moved on. I anticipate a similar pattern with SpaceX – a significant run-up followed by a potential leveling off, but potentially happening even faster due to SpaceX having fewer shares available.

Why This Matters for Our Corner of the Market

You might wonder why we’re featuring a rocket company on a site usually focused on mining and AI. The reason is this isn’t an isolated event – we expect to cover more companies like this in the future.

Anthropic filed confidentially for an IPO on June 1. OpenAI followed a week later, and its CFO has hinted at a listing as soon as Q4. If both happen, we get the three largest IPOs in history inside about six months, each one pulling tens of billions out of existing positions, each one repeating the same index mechanics and the same liquidity tax.

For the names we cover, that cuts two ways. The sector runs on outside capital. Every HPC buildout we’ve analyzed this year was funded by convertible notes, equity raises, or debt, and those deals price off market conditions. A market that keeps getting drained to feed mega-IPOs is a market where financing costs more and windows close faster. On the other hand, the money exiting SpaceX after the inclusion pop has to land somewhere, and AI infrastructure is the obvious nearby trade. Volatility in both directions, in other words.

Final Thoughts

After looking closely at everything, here’s what I think is happening: this isn’t primarily a story about space exploration, or even SpaceX itself. It’s mostly about a massive and rapid shift of wealth – more money moving around than the market can currently process – with even bigger changes already planned.

I expect the market will remain unstable and more volatile than current news reports indicate throughout the summer. Any periods of calm before the public offerings of OpenAI and Anthropic should be seen as short-lived. The initial public offering of SPCX will likely be very successful, due to limited shares available and strong demand. However, looking at Tesla’s performance in 2020, it’s better to be patient and avoid rushing to buy at peak prices.

If you’re thinking of investing right now, I’d suggest waiting a bit. The current market push needs time to settle down, shares from company insiders haven’t been released yet, and we often see better opportunities to buy *after* events like this, not immediately before.
