SpaceX says its IPO raised another $10.7 billion after underwriters exercised the greenshoe option

SpaceX said underwriters fully exercised the greenshoe, or over-allotment, option tied to its initial public offering, adding 83.3 million shares and increasing total proceeds by another $10.7 billion.

The company’s total IPO proceeds now stand at about $85.7 billion, up from roughly $75 billion in the original offering, according to reporting on the June 15 disclosure.

The added sale came after strong demand for the stock. A greenshoe option allows underwriters to buy additional shares at the IPO price when demand is strong enough to absorb more supply.

How the deal expanded

Coverage from the Wall Street Journal and MarketWatch said SpaceX disclosed that the full over-allotment option had been used. Barron’s reported the same underlying development and said the extra sale added about $11 billion to the deal.

The full exercise means the underwriters sold the maximum amount allowed under the offering terms. In this case, that meant an additional 83.3 million shares.

The reports described SpaceX’s offering as the largest IPO in history. The company’s first-day trading had already pushed its valuation above $2 trillion in cited coverage.

Market reaction

The stock rose again on its second day of trading, with coverage citing gains of roughly 19% to nearly 20% and a price around $192 per share.

The move suggested demand remained strong even after the enlarged share count was added to the market.

The company traded under the ticker SPCX in the reports.

What comes next

Further disclosure could still clarify allocation details, lockup terms, or any later corrections to the final share count or total proceeds.

For now, the public record points to an already historic offering that became even larger after underwriters used the full greenshoe option.

Investors will be watching whether trading stabilizes as the additional shares settle into the market and whether major holders begin disclosing positions.
