Since Donald Trump first expressed interest in taking over Greenland, several of the world's richest men have made major investments in the island. Amazon boss Jeff Bezos, Microsoft billionaire Bill Gates and Meta CEO Mark Zuckerberg have invested in the American mining company Kobold Metals, which extracts rare earths underground, since 2019. Why Trump wants to own Greenland Since 2022, OpenAI CEO Sam Altman has done the same. They are therefore among the people who have the prospect of a financial gain if the US president implements his plan to take control of Greenland and boost mineral extraction. Because while Donald Trump repeatedly highlights national security concerns as the primary reason for his great interest in making Greenland American, there are also many other interests at stake. The United States has openly stated that Greenland's subsoil is an important part of Donald Trump's interest. - It's about critical minerals. It's about natural resources. It's oil and gas. It's our national security, Trump's former national security adviser, Mike Waltz, told Fox News a year ago. The goal is, among other things, to become independent of countries like China in the supply of rare earths, which are used in the development of advanced technology such as electric cars, AI infrastructure and defense technology.

A previous analysis by The Guardian showed that tech moguls with investments in mining companies in Greenland, as well as oil executives and crypto billionaires with other interests in Greenland, collectively contributed at least $243 million to Donald Trump's 2024 election campaign. Several of the tech billionaires were also on the guest list for Trump's inauguration in January last year. According to Emily DiVito, an advisor at the economic think tank Groundwork Collaborative, there is a "closed loop" between the billionaires and Trump and Greenland. - These donations are investments, and they were made with specific results in mind, she told The Guardian. Minister's ties to mining company Along with Kobold Metals, another American mining company, Critical Metals Corp, is also in the process of establishing itself in Greenland. This is happening, among other things, with investments from the financial house Cantor Fitzgerald, whose chief executive for four decades was Howard Lutnick - that is, until he resigned from his post last year to become Trump's treasury secretary.
