Elon Musk’s net worth just got a big boost as he added $33.8 billion to his wealth in a single day.

The bump came as the businessman saw Tesla (TSLA) break records and beat Wall Street estimates for fourth-quarter and year-end vehicle deliveries.

This sent the electric automaker’s stock soaring 13.5% to $1,199.78 a share on Monday and added $144 billion to Tesla’s market value.

Tesla delivered 308,600 vehicles for the quarter, crushing analysts’ estimates for 267,000 units. Year-end deliveries were 936,172 units, up 87% over 2020, and beating Wall Street’s prediction of 897,000 vehicles for the year.

An analyst from Wedbush Securities called Tesla’s stock performance “jaw-dropping,” especially amid the auto industry's chip shortage and other logistical issues that are plaguing other manufacturers, Business Insider reported.

Tesla’s stock first reached a $1 trillion valuation in October as Hertz announced an order for 100,000 Model 3 EVs, which took Musk’s wealth to $340 billion, according to Business Insider.

However, Tesla’s stock dropped in November as Musk sold 10% of his stake to pay off an $11 billion tax bill. The stock rebounded in December, staying above $1 trillion.

Musk, who was already the richest person in the world, now has a net worth of $304 billion, according to Bloomberg's Billionaire Index.

He has surpassed the second-richest person in the world, Jeff Bezos, by a large margin. Bezos has a net worth of about $196 billion.

This year has proven to be a significant year for Musk, who was named Time Magazine’s 2021 Person of the Year. He also marked 2021 by appearing on “Saturday Night Live.”

As of Tuesday at 12:24 p.m. ET, shares of Tesla were trading at $1,149.88, down $49.90, or 4.16%.
