Elon Musk has become a dollar trillionaire again: his net worth exceeded $1 trillion, increasing by about $30.6 billion in a single day as shares of SpaceX and Tesla rose.

After peaking in June, Musk's wealth had dropped by more than half—from $1.45 trillion to less than $700 billion—due to a decline in SpaceX shares. Now, with the rise in SpaceX and Tesla stock, his total wealth has climbed back above the $1 trillion mark.
