SpaceX shares rose approximately 20% on Monday after the company announced its initial public offering proceeds reached $85.7 billion [1].

The surge marks a historic milestone for the space industry, signaling massive investor confidence in the company's commercial viability and its role in global infrastructure.

The increase in capital followed the decision by underwriters to exercise a “greenshoe” overallotment option [2]. This mechanism allowed underwriters to purchase an additional 83.3 million shares [2], which pushed the total funds raised to the record $85.7 billion [1].

Market activity on the Nasdaq exchange saw SpaceX shares climb 19.7 percent [3] during Monday trading. By the end of the session, the closing share price reached $192.8 [3].

This financial trajectory has pushed the post-IPO market valuation of the company to $2.5 trillion [4]. The scale of the offering reflects the unique position of the company in the launch and satellite markets, a dominance that few competitors can currently match.

While some reports estimated the total haul at $85 billion [5], the higher figure of $85.7 billion is supported by financial news outlets monitoring the overallotment process [1].

SpaceX shares rose approximately 20% on Monday

The exercise of the greenshoe option indicates that demand for SpaceX stock far exceeded the initial offering. By reaching a valuation of $2.5 trillion, SpaceX has transitioned from a private disruptor to one of the most valuable corporate entities in the world, providing the company with unprecedented liquidity to fund ambitious projects like Starship and the Starlink satellite constellation.
