Elon Musk is officially the richest he’s ever been (and the wealthiest person ever), according to Forbes’ calculations, as the planet’s richest person grew much richer as shares of the Musk-led publicly traded electric vehicle company Tesla soared after the election win of Musk’s close ally Donald Trump.

Musk’s net worth was a record $321.7 billion at market close Friday, getting a $7 billion boost as Tesla stock climbed 3.8% to a new 3.5-year closing high of $352.56 per share.
