In May, SpaceX experienced a historic first: the company successfully launched two NASA astronauts into space.
"This is a dream come true for me and everyone else at SpaceX," Musk said at the time. "I didn't even dream that this would come true."
Meanwhile, Musk's other venture, Tesla, has hit all-time highs in the stock market in recent weeks, particularly after the company reported blockbuster second-quarter earnings. Earlier this month, Musk became the fifth-wealthiest person in the world with a net worth of over $74 billion.
Bezos remains the richest person in the world. On one day earlier in July, Bezos added $13 billion to his net worth, nudging his wealth to over $189 billion.
While Bezos is facing government scrutiny over Amazon's potentially anticompetitive behavior, Amazon continues to thrive — the company reported a huge beat for its second-quarter earnings after a surge in demand during the coronavirus crisis.
Regardless of where Bezos' and Musk's rivalry stands, the two moguls won't stop being competitors anytime soon: these days, their companies are both submitting designs for lunar landers to NASA for a mission to return humans to the moon by 2024.
