Explained: SpaceX's IPO includes a 'greenshoe' option. Here's what that means

SpaceX's record $75 billion IPO includes a greenshoe option, allowing for the sale of an additional 15% of shares. This standard feature, designed to stabilize trading, could raise SpaceX an extra $11.2 billion if demand remains strong. The greenshoe option, named after a 1960 IPO, helps manage volatility for newly listed stocks.
