Balyasny Asset Management has disclosed ownership of 3.4 million shares in SpaceX, a position worth roughly $459 million at the company's IPO price of $135 per share. The Chicago-based multi-strategy hedge fund manages about $77 billion in assets, making the stake a meaningful but still modest allocation of around 0.6% of assets under management. The disclosure arrived weeks after SpaceX, trading as SPCX, went public on Nasdaq on June 12, 2026, in one of the largest IPOs in history. The stock jumped nearly 20% after listing and later climbed to around $226 before settling into more volatile trading. The filing does not say when Balyasny bought the shares or whether the fund entered at the IPO or in the secondary market, leaving its cost basis and unrealized gain unclear. Attention now shifts to an insider lockup (restriction on early share sales) expected to expire in early August 2026, when millions of shares held by employees, early investors and insiders may become eligible for sale on the open market.
