CAPE TOWN, July 7 — For a man whose fortune is built on rockets, electric cars and satellite internet, the numbers that define Elon Musk’s empire are often staggering. But one figure stands apart this week, as analysts and policymakers take stock of the billionaire’s sprawling business interests: the more than $20 billion in federal contracts and subsidies his companies have received from the United States government.
That sum, which includes funding from NASA and the Department of Defense, underscores a relationship that has grown increasingly symbiotic over the past two decades. Musk’s companies have become indispensable partners for American space and defence agencies, even as the entrepreneur himself has drawn criticism from environmental groups and political opponents alike.
The story of Musk’s rise begins in Pretoria, South Africa, where he was born on June 28, 1971. He founded SpaceX in 2002, a private aerospace manufacturer that has since developed the Falcon 9 rocket, the Dragon spacecraft, and the massive Starship launch system. Under his leadership as CEO and chief engineer, SpaceX has transformed the economics of spaceflight, reusing rocket boosters and driving down launch costs in ways that were once considered impossible.
Yet it is a more recent venture that Musk has described as critical to his long-term ambitions. He conceived the Starlink project in 2014, envisioning a constellation of low Earth orbit satellites that could deliver broadband internet to virtually any point on the globe.
The first Starlink satellites were launched in May 2019. Today, the network has grown into the world’s largest satellite constellation, with thousands of spacecraft orbiting the planet.
Revenue for Mars
Musk has been vocal about why Starlink matters beyond connecting remote homes and schools. He has stated that revenue from the satellite internet service is critical to funding SpaceX’s plans for colonising Mars. The logic is straightforward: Starlink generates cash flow that can be reinvested into developing the Starship system and the infrastructure needed to establish a human settlement on the Red Planet.
For Musk, Mars is not a distant fantasy but a concrete goal that requires a profitable business to sustain it. As of 2025, Musk’s net worth is estimated at $210 billion, placing him among the wealthiest individuals in the world.
That fortune is tied largely to his stakes in Tesla, Inc., where he serves as CEO, and in SpaceX. He also owns X Corp., the company that operates the social media platform formerly known as Twitter. The federal contracts and subsidies that have flowed to Musk’s companies — exceeding $20 billion — have drawn scrutiny from lawmakers and competitors.
NASA has contracted SpaceX for crew and cargo missions to the International Space Station, while the Department of Defense has used Falcon 9 rockets to launch national security payloads. These contracts have provided a steady revenue stream that has helped SpaceX weather the high costs of research and development.
Environmental concerns
But the rapid expansion of Starlink has not come without controversy. Environmental groups have criticised Musk over the atmospheric impact of satellite deorbits. When Starlink satellites reach the end of their operational lives, they are intentionally brought down to burn up in Earth’s atmosphere — a practice that some scientists warn could release pollutants and affect the upper atmosphere.
Musk has defended the practice as necessary for maintaining a modern satellite network. He has argued that the environmental impact is minimal compared to the benefits of global connectivity, and that Starlink’s constellation must be constantly refreshed with newer, more capable spacecraft.
The debate reflects a broader tension between the promise of space-based services and the environmental costs of operating thousands of satellites in low Earth orbit. The Starlink system itself is designed to provide broadband internet to regions that lack reliable terrestrial infrastructure. In conflict zones and disaster areas, the service has proven valuable for maintaining communications.
But the sheer scale of the constellation — with plans for tens of thousands of satellites — has raised concerns among astronomers about light pollution and interference with scientific observations.
A complex legacy
Musk’s companies have received over $20 billion in federal contracts and subsidies, including funding from NASA and the Department of Defense. That figure, while large, represents only a portion of the total investment that has flowed into the private space industry. Yet it highlights the degree to which Musk’s ventures have become intertwined with US government priorities.
For patients and families following these developments — and I say this as someone who typically writes about cancer research and health policy — there is an encouraging parallel. Just as early findings in medicine require careful validation before they can change practice, the promises of space-based technologies demand rigorous scrutiny.
The encouraging part is that independent oversight and public debate continue to shape how these systems are deployed. As of mid-2026, Starlink continues to expand its coverage, and SpaceX presses ahead with Starship development. Musk’s vocal advocacy for space exploration remains undimmed, and his companies show no signs of slowing their pursuit of contracts and revenue.
The path to Mars, it seems, runs through low Earth orbit — and through the federal budget.
