On what date did LinkedIn go public?

LinkedIn went public on May 19, 2011, when its shares began trading on the New York Stock Exchange under the symbol LNKD.

The company priced its initial public offering at $45 per share and sold 7.84 million shares. The IPO gave LinkedIn a public market valuation and provided capital for expanding its professional network, products, and international operations.

The first trading day became one of the most dramatic technology IPO debuts of its era. LinkedIn's stock surged during the session and closed at $94.25, more than doubling its offering price. That performance led to comparisons with other high-profile internet offerings, although the stock's early volatility also fueled debate about whether investors had pushed its valuation too high.

A common mix-up is May 18, the date LinkedIn announced its IPO pricing and the SEC declared its registration effective. Trading itself began the following day, May 19.
