Elon Musk's fortune rose by $65 billion to $1.04 trillion on Monday as shares of SpaceX and Tesla climbed, Bloomberg reported.

SpaceX shares have gained 13% since the start of October, while Tesla shares are up 6.7%, according to Bloomberg.

Musk's stakes in the two companies account for more than 98% of his net worth, the report said.

Musk's fortune last reached trillionaire status in June after SpaceX's initial public offering, but later fell as the company's shares declined, Bloomberg reported.
