What happened
SpaceX priced its IPO on 2026-06-11 at $135 per share for 555,555,555 shares, raising $75 billion - the largest IPO in history. Shares began trading on Nasdaq under SPCX on 2026-06-12, opened around $150 and closed at $160.95, roughly 19% above the offer price, with more than 500 million shares changing hands.
Why it matters
Because SpaceX had absorbed xAI earlier in 2026, this was also effectively the first public listing of a frontier AI lab. It gives xAI/SpaceXAI access to public capital to fund Colossus-scale compute and Grok training, and puts Grok’s progress under quarterly public-market scrutiny.
