Musk believes that the "star chain project" is "a key way for SpaceX to generate revenue" and estimates that the "star chain" can generate revenue of $30 billion a year, with a potential market size of up to $1,000bn.

SpaceX said its "Starlink" satellite Internet service project could enter the US stock market in a few years' time.

The company's CEO Elon Musk reiterated on Twitter on Monday: "We may IPO the Star chain project, but only if revenue growth is stable and predictable over the next few years, because the open market does not like erratic cash flow. "

Musk believes that the "star chain project" is "the key way for SpaceX to generate revenue." He estimated last year that the "star chain" could generate $30 billion a year. Earlier, he said that the potential market size of the "Star chain Project" is as high as $1 trillion and is expected to generate income from this year.

At one point, the SpaceX leadership discussed the idea. Gwynne Shotwell, president of SpaceX, said in February that the company might spin off the Star chain project. However, Musk said a month later that the company did not focus on the listing of the "star chain project", but was committed to keeping it "not bankrupt", and stressed the scarcity of satellite Internet service companies in early 2000. This statement played down market expectations.

The so-called "star chain project" means that SpaceX plans to build a "star chain" network of about 12000 satellites in space between 2019 and 2024 to provide high-speed Internet access to Earth from space.

According to the SpaceX plan, 12 batches of rockets will be launched to put 720 "star chain" satellites into orbit. Each launch mission consists of 60 satellites, each weighing about 260 kilograms. In November last year, the first batch of satellites were successfully launched, and so far more than 700 satellites have been successfully launched.

SpaceX told the Federal Communications Commission (FCC) in July that it was building a ground station and subscriber terminal system to connect users directly to its network, with 120 satellites and thousands of small terminals going into production each month.

This summer, SpaceX conducted a private Beta test. The company recently said that test results showed that the network was fast enough to support online videos, games and streaming movies. SpaceX said there was already a lot of potential demand for Star chain, with "nearly 700000 people" across the United States expressing interest in the company's upcoming service.

After further public testing, the company plans to provide "star chain" as a commercial service in the northern United States and southern Canada by the end of this year, and plans to "cover the world in 2021."
