Elon Musk is exploring mergers between Tesla and SpaceX to fund his ambitious AI projects, which are driving up costs across his companies. At the World Economic Forum, he shared his futuristic ideas but did not clarify how he plans to finance them.

Elon Musk has become the first person in history to achieve a net worth of $500 billion, driven primarily by a rise in Tesla's stock price and the growing valuations of his other companies, including SpaceX and xAI. This milestone highlights Musk's position as the world's richest person, just under a year after surpassing $400 billion.
