The company, officially known as Space Exploration Technologies Corp., will trade under the SPCX ticker symbol.

While IPO pricing typically works itself out as markets open, SpaceX took an unusual approach in setting the price well in advance. The company was testing its $135 share target with investors before its official roadshow started, the Financial Times reported. And that offering, which eschewed traditional IPO pricing practices, attracted four times the available shares, per Bloomberg.

As active trading gets underway tomorrow, SpaceX’s share price may sink or rise. But anecdotal reports suggest that big institutional investors and individual buyers are lining up to purchase shares in the 24-year-old technology company.

If the sale is as oversubscribed as the talkative bankers make it out to be, they have an option to bring an additional 83.3 million shares to market, which would raise another $11 billion at the company’s opening price.
