Thursday's announcement that Alibaba Group raised $21.8 billion in its initial public offering made it the largest U.S. IPO of all time, topping Visa's $17.9 billion deal in 2008.
The firm priced 320.1 million shares at $68 per share, raising a total of $21.77 billion, “assuming the underwriters do not exercise their option to purchase additional American depository shares.”
Rounding out the top largest five U.S. IPOs in history are utility ENEL SpA ($16.5 billion in November 1999), Facebook ($16 billion in May 2012) and General Motors ($15.8 billion in November 2010).
