Space Exploration Technologies Corp (NASDAQ:SPCX) is set to join the Nasdaq-100 index before the market opens on July 7, a move that will force an estimated $8.3 billion in passive buying from index-tracking funds. This influx represents approximately 44% of Friday's trading volume and over 8% of the company's total listed share pool, which stands at roughly $100 billion.
The addition comes less than a month after SpaceX began trading on June 12, following its highly anticipated initial public offering. Nasdaq Inc (NASDAQ:NDAQ) confirmed the index change, noting that the Nasdaq-100 has more than 200 tracking products with over $800 billion in combined assets under management.
Passive Buying Pressure
J.P. Morgan Chase & Co (NYSE:JPM) estimates that Nasdaq-100 inclusion alone could drive $4.3 billion in passive inflows. Separately, Stephens analyst Melissa Roberts projects that Russell index rebalancing, which occurred Friday, will require an additional $4 billion in buying. Combined, these passive flows total over $8.3 billion for a stock that saw only about $19 billion in turnover on Friday, with nearly half of that activity concentrated in the final minutes of trading.
The concentrated buying pressure is exacerbated by SpaceX's limited free float. Most shares remain locked up with founder Elon Musk, insiders, and employees, leaving only about $100 billion in shares available for trading. This scarcity amplifies the potential market impact of index-driven demand.
Stock Performance and Valuation
SpaceX shares closed Friday at $153.23, approximately 32% below their June 16 intraday high of $225.64. While still above the IPO price of $135, the stock has cooled considerably after a 67% surge in its first days of trading. At current levels, SpaceX trades at roughly 107 times estimated 2025 sales—a stark contrast to Nvidia Corp (NASDAQ:NVDA), which recently traded at 21 times sales.
The company posted a $4.9 billion loss last year, raising questions about its valuation. "Clearly, there's a lot of demand," said Michael Field, chief equity market strategist at Morningstar Inc (NASDAQ:MORN). "We think the stock is overvalued."
Index Constraints and Risk Transfer
Funds like the Invesco QQQ Trust (NASDAQ:QQQ), Invesco Nasdaq 100 ETF (NASDAQ:QQQM), and iShares Russell 1000 ETF (NYSEARCA:IWB) must buy SpaceX shares regardless of valuation to track their benchmarks. This dynamic shifts risk from active stock pickers to passive index investors who may not have chosen to own the stock otherwise.
The S&P Global Inc (NYSE:SPGI) has not updated its S&P 500 admission requirements for megacap IPOs, still requiring profits in both the latest quarter and the trailing four quarters—a threshold SpaceX does not meet.
Debt Market Developments
SpaceX bonds weakened following the company's launch of a $25 billion debt deal, as reported by the Financial Times. The yield on the 10-year notes approached 6%, with spreads over Treasuries exceeding 1.6 percentage points. The new debt refinances a $20 billion bridge loan tied to the xAI acquisition, and additional capital will be needed for AI-related data centers, hardware, and power supply.
Russell reconstitution activity added to the drama. "This week's reconstitution could mean a really massive trade," Steven DeSanctis, equity analyst at Jefferies Financial Group Inc (NYSE:JEF), told Reuters. Roberts noted that Friday marked a "key liquidity day," with reconstitution-day trading estimated to hit nearly $150 billion.
