Thanks to skyrocketing share prices, yesterday was a very big payday for Tesla founder Elon Musk. The already wealthy businessman added another $1.1 billion, ten percent of his net worth, to his overflowing wallet yesterday after Tesla's shares hit $248. This time last year, TSLA was trading at roughly $34 per share.

Tesla's latest jump in a year that has already seen share prices climb 65 percent is thanks to positive reports from Consumer Reports on the company's Model S electric sedan, and some kind words from Morgan Stanley about the brand's plans for a battery factory.

Despite all the good news for Tesla yesterday, not all of the $1.1 billion Musk earned came from his automotive pursuits. SolarCity, which Musk is also the largest shareholder in, saw its share prices jump 3.1 percent, as part of a 43-percent jump in 2014.

According to Bloomberg, Musk's latest stock earning makes him the second largest wealth earner among US billionaires this year, behind Facebook's Mark Zuckerberg.
