Elon Musk's fortune increased by $65 billion on Monday to reach $1.04 trillion according to the Bloomberg Billionaires Index.
The rise in net worth was driven by climbing values in his stakes in SpaceX and Tesla Inc., with SpaceX shares up 13% since October start.
The gains mark the first time in three months that the tech mogul's fortune required 13 numerals, supported by renewed optimism at both companies.
