SpaceX remained sharply above its IPO price in continued post-listing trading, with U.S. overnight trading putting the shares at $212 versus a $135 IPO price and valuing the company at about $2.77 trillion. That move placed SpaceX in the global top five by market value after surpassing TSMC and Amazon, while a Polymarket contract on the world’s most valuable company at the close of Dec. 31, 2026 assigned SpaceX an 8% chance, with volume above $257,000. The rally follows heavy IPO demand, strong retail participation, underwriters’ exercise of an option for 83.33 million additional shares that lifted proceeds to about $85.7 billion, and Elon Musk’s statement that annual revenue could reach $1 trillion by 2030. The stock’s debut has also driven unusually strong activity in crypto-linked products tied to SpaceX, including SPCX perpetual futures and SPCXON, as traders used tokenized and derivative markets to gain round-the-clock exposure to the company’s price.
