Richard Branson’s Virgin Galactic Holdings Inc. became the first space-tourism business to go public as it began trading Monday on the New York Stock Exchange with a market value of about US$1 billion.

The listing, carried out through a merger with shell investment company that was already trading, secures vital new funding for Branson as the British entrepreneur competes with fellow billionaires Jeff Bezos and Elon Musk in what’s been dubbed “the new space race.”

Investors are being asked to back a project that’s already been running for 15 years without yet achieving a first commercial launch, and which came close to folding following a fatal crash during a 2014 test flight.

Virgin Galactic combined last week with the investment firm, Social Capital Hedosophia, rather than conduct an initial public offering. That avoided a costly investor roadshow and the challenge of selling shares in such a company likely to be perceived as high risk by many.

The new entity climbed 5.3 per cent to $12.41 at 9:32 a.m. in New York on Monday, its first day trading under the ticker SPCE. The shares rose 11 per cent Friday after the combination was completed, handing Virgin Galactic more than US$450 million in primary proceeds.

Virgin Galactic is one of a trio of billionaire-backed space startups, each tapping different technologies. Branson is using an aircraft to carry a spaceship to high altitudes, where it blasts away, while Amazon.com Inc. founder Bezos’s Blue Origin relies on more-conventional rockets and Tesla Inc. chief Musk’s Space Exploration Technologies Corp. deploys reusable launchers.

While transporting satellites has been a focus for SpaceX, Branson is chasing the tourism market, planning a first commercial flight next year. Blue Origin plans to take payloads and tourists to the edge of space on an 11-minute flight, while Musk has joined the race with a pledge to send passengers to the moon, Mars and beyond.

Branson said last week that Virgin Galactic also is interested in developing hypersonic airline flights after Boeing Co.’s future-technologies arm pledged US$20 million for a minority stake. That could mean linking U.S. cities in a matter of minutes and, ultimately, the U.S. and U.K. with Australia in just a few hours.

Social Capital Hedosophia founder, Sri Lanka-born Chamath Palihapitiya, will contribute US$100 million to the venture and become its chairman. Virgin Galactic has raised more than US$1 billion since it was founded in 2004, initially from Branson, with an Abu Dhabi investment company taking a stake in 2010.
