SpaceX has hurtled to the top of the launch industry over the past decade, last year bringing in more revenue than any other rocket company, according to Jefferies on Sunday.

"While SpaceX is newer to the market, their lower price point has allowed them to outpace peers in estimated annual launch revenues," Jefferies analyst Sheila Kahyaoglu wrote in a note to investors, in a "deep dive" report.

Jefferies broke out the estimated 2018 revenues for eight "heavy launch" companies, which compete in the most expensive part of the rocket market. The massive rockets, standing as tall as skyscrapers, cost anywhere between $62 million to $350 million. Jefferies charted last year's launch revenues for SpaceX, United Launch Alliance (also known as "ULA," a joint venture of Boeing and Lockheed Martin), Northrop Grumman, Europe's Arianespace, Russia's Khrunichev, India's ISRO and Japan's Mitsubishi Heavy Industries. Jefferies also included Blue Origin as a competitor, although its New Glenn rocket is not expected to launch before 2021.

SpaceX logged $2 billion in launch revenue last year, the report said. In total, Jefferies estimated these companies' rockets brought in about $8 billion in revenue in 2018.

Jefferies said SpaceX, as a relatively new entrant, has helped introduce "a level of price competition, which is a positive for launch market customers." These rockets largely cater to "a government market," where ULA and the internationally-backed companies have previously dominated.
