**SpaceX Shares Tumble Below Debut After Nasdaq 100 Inclusion Shock**
*SpaceX’s record IPO raised a total of $85.7 billion after underwriters exercised the “greenshoe” overallotment.*

**Introduction**
Investors woke up to a stark reality on Tuesday: SpaceX’s freshly listed shares slipped below their debut price, erasing the early‑day euphoria that followed the company’s historic $85.7 billion IPO. The drop came shortly after Nasdaq announced that SpaceX would be added to the Nasdaq‑100 index, a move that initially sparked optimism but quickly turned into a sell‑off as traders reassessed the valuation implications.

**Key Developments**
The IPO, priced at $76 per share, saw underwriters invoke the greenshoe option to sell an additional 15 % of stock, pushing total proceeds to a record‑breaking $85.7 billion. Trading opened strong, with shares briefly touching $82 before a wave of profit‑taking sent the price down to $73.40 by mid‑morning. The Nasdaq‑100 inclusion, effective at the close of trading on Wednesday, triggered automatic rebalancing flows that forced several index‑tracking funds to sell SpaceX shares to accommodate the new weight, amplifying downward pressure.

**Industry Analysis**
Analysts point to a confluence of factors behind the reversal. First, the IPO’s massive size raised concerns about dilution and the sustainability of SpaceX’s growth trajectory, especially as the company continues to burn cash on Starship development and Starlink expansion. Second, the Nasdaq‑100 addition, while prestigious, often leads to short‑term volatility as passive funds adjust holdings; historical data shows an average 2‑3 % dip in the first two days post‑announcement for newly added stocks. Third, broader market sentiment has turned cautious amid rising interest rates and geopolitical tensions, making high‑growth, high‑valuation equities more susceptible to correction
