In a notable divergence from tradition, several billionaire business leaders, including Meta CEO Mark Zuckerberg, OpenAI's Sam Altman, and Uber's Dara Khosrowshahi, have opted to attend Donald Trump's inauguration in Washington, D.C., on January 20 instead of the World Economic Forum in Davos, Switzerland.

U.S. President Trump is to speak to an international audience for the first time after returning into the White House with a speech and Q&A by video conference to the World Economic Forum’s annual event in Davos on Thursday.
