Tesla’s share is rising on Monday, as Ilon Musk bought more than 2.5 million shares worth about $ 1 billion (850m euros) of his company.

Mask bought different quantities of shares at different prices on Friday, according to a document deposited with the regulators, Euronews notes.

This move can be regarded by markets as the billionaire’s belief for the future of the company.

What should happen to become a trillionaire

Earlier this month, Tesla published a proposed remuneration package for MASK, which would probably make him the world’s first trillionaire if he achieves a series of extremely aggressive goals for the company the next decade.

Tesla said in a deposit to the regulators that it will give MASK shares up to 12% of the company in twelve separate packages if the company achieves certain performance targets, including mass increases in car production, stock price and operating profits.

If approved by shareholders, the new remuneration package could make Musk the first executive in the world with property over one trillion dollars.

To get his first share package equivalent to 1% of the company, Musk would have to convince investors on the Stock Exchange that Tesla is worth a total of $ 2 trillion (1.70 trillion euros), twice as much as the value of it today, and also to achieve it.

In order to receive all the shares offered and to make the first person in the world of trillion dollars, it would require its market value to increase to $ 8.5 trillion (7.21 trillion euros), twice the value of the most valuable company in the world.

Tesla has seen this year’s sales fall, mainly due to the reactions to Musk’s relationship with Donald Trump. Tesla is also facing increasing competition from Detroit’s major automakers and especially China.

Investors are increasingly worried about the company’s course, as Musk spent so much time in Washington this year.

Tesla is set to hold the annual General Assembly of its shareholders on November 6, where investors will vote for the new remuneration package.
