Musk may be the richest man in the world in theory, but he is not.

Who does that?

The CEO of the company says that the Russian President is also a CEO.

According to the website, Musk told the CEO of Business Insider that he thinks Putin is wealthier than him.

Late last year Musk overtook Jeff Bezos to become the richest man in the world. According to Forbes, Musk was worth $270 billion.

How much is Putin worth?

No one knows.

According to the Kremlin, Putin earns an annual salary of $140,000. His publicly disclosed assets include an apartment, trailer, and three cars.

He may be the wealthiest man in the world according to some experts.

Putin is rumored to be the owner of a mansion that sits atop a cliff overlooking the Black Sea. This coastal property is reputed to be the largest private residence in the country and serves as his private palace.

It is estimated to be worth over $1 billion.

The palace is owned by a wealthy businessman, according to the Kremlin. Russian analysts say that no businessman can have properties guarded by the FSB with a no-fly zone over them.

He also owns 19 other houses and 700 cars, as well as a $716 million plane called The Flying Kremlin that has a toilet made of gold. He owns a megayacht that was designed by a nuclear submarine maker from the Russian navy.

The Panama Papers revealed a network of secret offshore deals and loans worth $2 billion and pointed to Putin.

Putin admits that he is the wealthiest man in Europe but in the whole world. The people of Russia have twice given me the leadership of a great nation such as Russia. He said that he believed that was his greatest wealth.

Musk said that he couldn't let Putin take over Ukraine.
