No billionaire has done more than Elon Musk to help Donald Trump win the US presidential election. The boss of both Tesla and SpaceX will soon find out whether his actions will bring rewards or backfire.

Expanding political connections have long proven Musk's courage, but this time he is getting more than just a White House ally. Trump has promised to give him an official role responsible for cutting government spending, giving Musk the power to influence policies and regulatory agencies of his vast business empire.

"He's very unique, different, a super genius," Trump said of Musk in a speech to supporters the night before. "We have to protect our geniuses. We don't have that many like him."

In any case, Tesla's stock price has been soaring. Due to investors hoping to profit from Trump's return to the White House, the stock surged 15% during the US session. Musk also posted a chart Wednesday morning, claiming record usage of his social network X.

Watch: Trump wins, Tesla's stock price surges. Will Musk's political gamble continue to pay off? Ed Ludlow reports.

"Enjoy it," he wrote in another post, along with a photo parodying him carrying a sink into an oval office, a nod to when he carried a sink into Twitter's headquarters after taking over Twitter.

In the past few months, Musk has been Trump's most ardent agent. The world's richest man has campaigned for Trump on X, hosted town hall meetings in crucial battleground state Pennsylvania, and appeared at Trump's rally in Madison Square Garden, overshadowing Trump's running mate JD Vance.

To support Trump and fiercely contest Republican congressional seats, Musk has contributed over $0.13 billion, making him one of the top donors in this election cycle. On election day, Musk flew from voting in Texas to Florida on a private jet to watch the election results at Mar-a-Lago with Trump and his family. Musk's political action committee released a photo of him sitting alongside Trump and UFC president Dana White.

"Elon Musk may be new to politics, but as a billionaire and technology tycoon, his full support for President Trump is significant," said Jondavid Longo, head of the organization 'Early Vote Action' dedicated to registering Republican voters in Pennsylvania. Trump's victory in Pennsylvania is crucial for his overall win; he won the state during his first presidential campaign in 2016 but lost in 2020. Musk donated 1 million USD to 'Early Vote Action'.

Musk stands to gain significant economic benefits from the incoming Trump administration. Managing a business empire consisting of six companies, some of which have close ties to the US federal government. SpaceX has become an increasingly important partner for NASA and the US Department of Defense, with contracts worth billions of dollars. Tesla has staked its financial future on developing self-driving taxis, a high-risk business facing significant regulatory hurdles.

According to the billionaire index, Musk's personal wealth fluctuated significantly during the four years of Biden's presidency, reaching as high as 340 billion USD and as low as 124 billion USD. Overall, it has been on an upward trend. As of election day, his net worth is 263.8 billion USD.
