SpaceX raised $54 billion in its IPO on June 12, marking the largest valuation for a newly-traded U.S. company, but analysts say the firm left about $17 billion in potential proceeds on the table. Shares opened at $135 and closed at $160.75, a 19% gain, which some view as a modest first-day pop given the company’s capital needs for its AI expansion, according to fortune.com.

The offering was hailed for balancing a strong valuation with gains for institutional and select retail investors, avoiding an excessive first-day price surge that could have penalized SpaceX. However, the sizable immediate profits for investors who bought at the IPO price highlight the opportunity cost for SpaceX, which requires substantial funding to support its AI growth initiatives. The allocation process also generated lucrative 'soft dollar' trades for bankers involved, fortune.com reported.

This IPO is notable as the largest U.S. enterprise debut by valuation, yet the $17 billion left on the table is unprecedented. The funds could have significantly bolstered SpaceX’s capital expenditures, especially for its AI franchise, which CEO Elon Musk has identified as the company’s main growth engine. The balance between raising capital and rewarding early investors remains a key tension in mega-IPOs like this one, fortune.com noted.

SpaceX’s shares closed at $160.75 on June 12, with the company’s valuation exceeding $300 billion. The next major financial update will come with the company’s quarterly earnings report, which investors will scrutinize for progress on its AI projects and capital deployment.
