Space Exploration Technologies Corp. (NASDAQ:SPCX), widely known as SpaceX, enters a critical week as its stock faces a new test: whether index funds can absorb a massive wave of passive demand. The company's shares, which closed at $153.23 on Friday, are up 13.5% from the IPO price of $135 but remain roughly 32% below the 52-week high of $225.64. With a market capitalization of approximately $2 trillion, the stock's thin public float and heavy capital requirements are now center stage.
Index Fund Influx to Drive Near-Term Price Action
The primary catalyst for SpaceX stock in the coming days is the forced inclusion in major equity indexes. According to Reuters, Russell index funds are required to purchase over $4 billion worth of shares, while J.P. Morgan estimates Nasdaq-100 passive inflows will reach $4.3 billion. Combined, these inflows represent about 8.3% of the listed float, which stands at just $100 billion. Most shares remain held by founder Elon Musk, insiders, and employees, limiting the supply available for trading.
This index-driven demand is expected to overshadow fundamental factors in the near term. The stock jumped 0.15% on Friday ahead of its addition to Russell U.S. indexes after the close, with roughly $19 billion in shares changing hands—nearly half of that in the final minutes of trading. The Russell rebalancing, which took effect Monday, June 29, forces funds like the iShares Russell 1000 ETF (NYSEARCA:IWB) to hold SpaceX before the market opens.
Nasdaq-100 Entry and ETF Impact
Looking ahead, Nasdaq Inc. (NASDAQ:NDAQ) will add SpaceX to the Nasdaq-100 index before the open on July 7. This move will place the stock in popular exchange-traded funds such as the Invesco QQQ Trust (NASDAQ:QQQ) and the Invesco Nasdaq 100 ETF (NASDAQ:QQQM). For these funds, the purchase is mechanical—dictated by index rules rather than valuation analysis. “Clearly, there’s a lot of demand, that’s why they fast-tracked the integration into the index,” said Michael Field, chief equity market strategist at Morningstar Inc. (NASDAQ:MORN). “A lot of people will be happy with it. Some fund managers, and the skeptics, us included, are less so. We think the stock is overvalued.”
Valuation Concerns and Financials
Bearish arguments persist despite the index-driven buying pressure. SpaceX reported a net loss of $4.9 billion last year, and its shares trade at roughly 107 times expected 2025 sales, a steep multiple compared to Nvidia Corp. (NASDAQ:NVDA), which trades at about 21 times sales. The company’s capital needs remain substantial, as it recently launched a five-part notes sale aiming to raise at least $25 billion—its first foray into investment-grade dollar bonds. Proceeds will be used to pay off bridge loans and fund general spending, including tens of billions for AI-related data centers, hardware, and power. The bond offering reportedly attracted nearly $85 billion in orders, according to a source cited by Reuters.
IPO Details and Market Reception
SpaceX priced its IPO at $135 per share on June 11, selling 555.56 million shares for a total of $75 billion, giving it a valuation of $1.77 trillion—the largest U.S. IPO on record. “The real test will be how the market digests the IPO over the next several weeks, not just one day,” said Adam Sarhan, chief executive at 50 Park Investments. IPO expert Jay Ritter, a professor at the University of Florida, noted, “There’s a long way to go to catch up with the profitability” of larger tech names, while Matthew Kennedy at Renaissance Capital added, “Some stocks are expensive and stay expensive.”
Index Inclusion Timeline and S&P 500 Outlook
S&P Global Inc. (NYSE:SPGI) has confirmed it will not fast-track SpaceX into the S&P 500, sticking to its rule that requires at least one year of trading before eligibility. As a result, the immediate focus remains on the Russell rebalancing this week and the Nasdaq-100 inclusion on July 7. These events are expected to be the next clear catalysts for the stock, as passive fund flows continue to dictate near-term price action.
