SpaceX's Stock Sits Below Its June IPO Open. Is That a Warning Sign for Anthropic?

Anthropic has filed its S-1 with the U.S. Securities and Exchange Commission, a key step ahead of a possible IPO, drawing investor attention to the AI lab. The article argues that the stock-market path of SpaceX may offer a cautionary template. SpaceX began trading on June 12 at $150 a share, jumped above $225 in its first days, then slid to around $108 before partially rebounding—still below its opening price. The comparison is not about SpaceX specifically, but about common IPO dynamics: concerns over heavy AI infrastructure spending, first-year lock-up expirations that can add selling pressure, and sector or market cyclicality. Competitors like OpenAI and Alphabet face massive adoption, too.
