KEY POINTS
- SpaceX (NASDAQ:SPCX) joins the Nasdaq-100 before Tuesday's open, forcing every fund that tracks the index to buy the stock.
- J.P. Morgan estimates up to US$4.3 billion of buying from the QQQ fund alone, and as much as US$27 billion across all index funds.
- That demand hits a stock where only 3-5% of shares trade freely, a tight squeeze that could lift the price short term.
- The catch: locked-up shares start freeing up from 6 August, which could flood the market and reverse the pop.
SpaceX (NASDAQ:SPCX) officially joins the Nasdaq-100 before the market opens on Tuesday, and that single event forces every fund tracking the index to buy the stock. The scale is huge: up to US$4.3 billion from the QQQ fund alone, and as much as US$27 billion across all index trackers. Here is what makes it unusual. Only 3-5% of SpaceX shares actually trade freely, so this wall of forced buying is hitting a tiny supply. The real question for investors is whether that squeeze is worth chasing, or a trap.
Why Index Funds Are Forced to Buy SpaceX Today
Here is how this works. When a stock joins the Nasdaq-100, every fund that copies the index must add it, no matter the price. SpaceX qualified in record time, just 15 trading days after its June IPO, because Nasdaq loosened its rules to let giant new listings in fast.
In our view, that speed is the whole story: the buying is mechanical, driven by index rules, not by anyone deciding SpaceX is cheap.
The demand is enormous against the supply. With only 3-5% of shares in public hands, index funds are chasing a very small pool. That mismatch can push the price higher short term, which is why the stock has held firm near US$160 ahead of the event. But a price driven by forced buying tells you nothing about whether the business is worth US$2.1 trillion.

The Catch: A Lockup Cliff Is Coming in August
This is where investors need to be careful. The forced buying is a one-off. Once index funds finish rebalancing, that support fades, and a much bigger force arrives. Once SpaceX reports its first results, expected around 6 August, the first tranche of locked-up shares becomes saleable, letting insiders offload about 20% of their holdings.
That matters because the numbers are staggering. A former Nasdaq chief warned the unlock could eventually release up to US$800 billion in shares onto the market. The implication is clear: today’s tight supply is temporary. As locked shares free up between August and December, the squeeze lifting the stock now could quickly flip into selling pressure.
The Investor’s Takeaway for SPCX
So should you buy the hype? We would be cautious. SpaceX is a remarkable company, with Starlink now past 10 million subscribers and around US$27.8 billion a year in AI computing contracts.
But at a US$2.1 trillion value, it trades at roughly 54 times its forecast 2026 sales, and more than 100 times last year’s, while still losing money after a US$4.28 billion loss last quarter. That is a steep price for a stock this early in its public life.
The concern is that index buying is being confused with real demand. History shows these inclusion pops often fade once the forced buying ends. In our view, the smarter move is to wait for the 6 August results and the lockup wave to pass, rather than chase a price propped up by funds that have no choice but to buy. The business is world-class, but paying any price for it, right before a supply flood, is how investors get hurt.
