SpaceX went public on June 12 under the ticker SPCX on the Nasdaq, raising between $75 billion and $86 billion. This marked the largest initial public offering in history by both valuation and capital raised.
Shares opened at $150 and closed near $161, a roughly 19% gain on debut. More than 500 million shares traded hands on the first day, pushing the company's market valuation to approximately $1.75 trillion.
The IPO triggered the fastest entry into the Nasdaq-100 Index in history. SpaceX earned its spot on July 7, just 15 trading days after going public, aided by a new "fast entry" rule for mega-cap listings.
This forced major Nasdaq-tracking ETFs like Invesco's QQQ to rebalance significantly, buying SpaceX shares to match the updated index. The resulting activity made June 2026 the busiest month for the exchange's largest ETFs in six years, with record inflows from investors seeking exposure.
