SpaceX (SPCX) fell to $151, erasing most IPO gains after its fast‑track Nasdaq‑100 inclusion, prompting traders to watch passive buying and upcoming lock‑up

SpaceX shares dropped to about $151 on Tuesday, a 3% decline that wiped out nearly all the gains made since its historic IPO, as the company’s fast‑track entry into the Nasdaq‑100 triggered a wave of profit‑taking and speculation about the durability of the rally [2].

| At a glance | |
|---|---|
| Price | $151 (down ~3%) |
| IPO price | $135 (opened at $150) |
| Post‑IPO high | $225 |
| Nasdaq‑100 weight | ~1.3% (≈$75 bn market cap) |

## Profit‑taking after a blistering debut  
SpaceX’s IPO was the largest ever, pricing at $135 per share and opening at $150, before surging to an intraday high of $225 as investors chased the company’s launch and Starlink ambitions [2]. By midday on the day of its Nasdaq‑100 inclusion, the stock was trading around $151, barely above the opening level and erasing almost all of the post‑IPO upside. Analysts attribute the pullback to early investors locking in profits, heightened valuation concerns, and the absence of a fresh operational catalyst beyond the index addition [2].

## Index inclusion and its limited boost  
The Nasdaq‑100 addition makes SpaceX the fastest newly public firm ever to join the benchmark, assigning it an estimated 1.3% weight based on a $75 bn market cap—roughly the 21st spot in the index [3]. This modest weighting means passive funds that track the Nasdaq‑100 will need to buy only a limited share of the tradable float, tempering any sustained price lift. Market participants expect a short‑term tailwind from mandatory purchases, but analysts warn that once this mechanical buying subsides, the stock will revert to scrutiny of revenue growth, cash flow, and valuation fundamentals [2][3].

## Valuation concerns remain front‑and‑center  
Morningstar argues that even after the decline, SpaceX’s shares remain priced at a premium that could be “less than half its IPO price” in intrinsic value terms, suggesting limited upside if growth expectations are not met [2]. The company still faces execution risks in scaling Starlink, delivering Starship, and balancing commercial, government, and defense contracts, all of which will shape future investor sentiment.

## What to watch  
- **Lock‑up expirations** – Upcoming unlock periods could add selling pressure as insiders and early investors unload shares.  
- **Starlink subscriber growth** – Quarterly updates on subscriber numbers and revenue will test the premium valuation.  
- **Passive fund buying** – Tracking the actual inflow into Nasdaq‑100 ETFs will indicate whether the index inclusion provides any lasting support.

SpaceX’s rapid price swing underscores how high‑beta, headline‑driven stocks can swing sharply on mechanical forces like index inclusion, leaving the longer‑term investment case dependent on concrete operational performance rather than market hype.
