THE FUSE

Elon Musk's net worth has hit $1.4 trillion on the Forbes real-time billionaires tracker, four days after SpaceX completed the largest initial public offering in stock market history and confirmed his status as the world's first and only trillionaire. Bloomberg's Billionaires Index, which uses a different methodology and updates at the daily close of New York trading, put the figure at $1.27 trillion as of June 15. Both numbers agree on the fundamental reality: no human being in the history of recorded commerce has ever been this rich.
