Top tech leaders Elon Musk, Jeff Bezos and Mark Zuckerberg are set to attend the inauguration of US President-elect Donald Trump on January 20, according to people involved in planning the event, NBC News reports. Their attendance at the ceremony included them among prominent political and business figures, indicating the importance of their relationships to the incoming administration.

Tesla and SpaceX CEO Elon Musk expressed his excitement over his prominent position at the event, saying on social media platform X that he felt “honored” to be a part of the proceedings. Musk has been an open supporter of Trump, contributing more than a quarter billion dollars to help his campaign and being closely aligned with the president-elect’s policies. He is also co-leading a new advisory body, the Department of Government Efficiency, in which Musk will likely play a major role in shaping the new administration’s approach to business and governance.

Meta CEO Mark Zuckerberg is also actively engaging with the Trump administration after years of strained relations. Meta contributed $1 million to Trump’s inaugural fund, and Zuckerberg is co-hosting a reception with Republican megadonor Miriam Adelson. This change in stance is major, as Zuckerberg previously banned Trump from Facebook and Instagram in 2021 following the January 6 Capitol riots. However, they have revamped Meta’s lobbying and content moderation policies to better align with the incoming Republican government.

Amazon founder Jeff Bezos will also attend the inauguration, despite past tension between Trump and his The Washington Post, which has refrained from endorsing a candidate during the 2024 election. Amazon contributed $1 million to the inaugural fund, also highlighting Bezos’ desire to build rapport with the new administration, awarding his company major federal contracts through its cloud computing arm, Amazon Web Services.

These three tech giants—Musk, Zuckerberg, and Bezos—have reportedly amassed vast wealth and global influence through their respective companies, with a combined net worth of $885 billion. Their attendance at Trump’s inauguration signals a strategic alignment with the incoming administration, as each of their businesses will benefit depending on how U.S. policies around technology, trade and regulation evolve during Trump’s second term. Or will have to face challenges.

With Meta facing an antitrust case, Amazon relying on federal contracts, and SpaceX’s space ambitions closely tied to government projects, these business leaders’ involvement in Trump’s inauguration is a consideration for their companies’ growth.
