[Into the World of AI] Ahead of IPO, a Closer Look at SpaceX’s Cash Cow 'Starlink'

Starlink Reaches 10.3 Million Subscribers as of March This Year

Massive Space Launch Losses Offset by Starlink’s Profits

With SpaceX set to be listed on the US Nasdaq on June 12 next month, the company's financial structure has been disclosed for the first time, drawing attention to its only profitable business: the satellite internet service 'Starlink.' More than half of SpaceX's revenue comes from Starlink, which now serves as the company's effective 'cash cow.' This reveals that SpaceX is aiming to be not just a 'rocket company,' but rather a 'satellite communications company.'

According to SpaceX's initial public offering (IPO) filing submitted to the US Securities and Exchange Commission (SEC) on May 20 (local time), the company's revenue for the first quarter of this year was $4.7 billion, but it posted a net loss of $4.276 billion. Given that the net loss for the same period last year was $528 million, the deficit has widened significantly.

Specifically, the 'Connectivity' segment, which includes the Starlink business, recorded $3.257 billion in revenue and $1.188 billion in operating profit in the first quarter, accounting for 69% of the company's total revenue. In contrast, the 'Space' segment, which includes launch vehicles, posted $619 million in revenue and an operating loss of $662 million. This clearly shows that while rocket launches help to bolster SpaceX's technology and brand, Starlink is the driver of real cash flow. With the space launch business and AI chatbot Grok incurring significant losses, revenue from Starlink is effectively offsetting these deficits.

Mountainous, Maritime, and War Zones Possible... Huge Market Expansion Potential

Global investors are focusing on Starlink because it is the overwhelming leader in low-Earth orbit satellite internet. Starlink provides internet services using a vast number of satellites orbiting in low-Earth orbit instead of terrestrial base stations. Not only does it offer global coverage, but it is also available in mountainous, maritime, and war zones—areas where traditional telecom carriers have struggled to penetrate. It is expanding into aviation and maritime internet, military communications, and internet services in developing countries, making its market expansion potential a particularly attractive investment point.

Earlier this year, SpaceX submitted an application to the US Federal Communications Commission (FCC) to launch up to one million low-Earth orbit satellites. Its subscriber base is also growing rapidly: Starlink had about 4.6 million subscribers in 2024, up from about 9 million last year. As of March this year, the number of subscribers had increased to 10.3 million.

In particular, the military and defense sector is expected to be the most profitable area. SpaceX's close partnership with the US Department of Defense is seen as a strategic move with this in mind. Industry observers note that Starlink's exclusive low-Earth orbit satellite network presents extremely high barriers to entry, and that it is likely to become the backbone of global communications infrastructure in the long term, providing strong growth prospects. Competitors are also entering the market in response to this growth potential, with Amazon, Blue Origin, and Viasat among those cited as rivals to SpaceX.

Starlink is accelerating its entry into the Korean market as well. The Korean government officially approved Starlink's domestic satellite internet service in May last year. Recently, SpaceX has been strengthening cooperation with companies such as KT SAT and SK Telink, and is pursuing partnerships with the shipbuilding and maritime industries. In the current domestic market, Starlink's competitor is OneWeb, operated by France's Eutelsat, while the Korean government is also working on developing its own low-Earth orbit satellite network. The Ministry of Science and ICT and the Ministry of National Defense are discussing strategies for low-Earth orbit satellite communications and a 6G-based integrated network.

An industry insider from the Korean telecommunications sector commented, "Korea's internet infrastructure is among the world's best, and because telecommunications are a key infrastructure directly linked to national security, the impact of Starlink could be somewhat limited. Instead of the consumer market, Starlink is more likely to target the B2B sector and is expected to expand its influence in the enterprise market for shipping, aviation, and defense."

Experts forecast that if Starlink expands beyond satellite internet to become a platform encompassing direct-to-device communication (D2C) and even space data centers, inevitable changes will come to the domestic mobile telecommunications market. Although the impact remains limited for now, if direct-to-device communication becomes mainstream in the future, the revenue base of domestic telecom operators could be undermined. As a result, there are calls for Korea to raise its level of response, with close attention being paid to SpaceX’s next moves as it secures significant funding through its IPO.
