If you want to know who is the richest person in the world in 2026, the answer is Elon Musk. Forbes currently ranks him at number one on its Real Time Billionaires list. His estimated wealth was about $862.4 billion on August 26, 2026.
Billionaire wealth can rise or fall each day because much of it links to company shares and private company values.
Who Is the Richest Person in the World in 2026?
Elon Musk is the richest person in the world. His main sources of wealth are listed as Tesla and SpaceX. Forbes also identifies him as a co-founder of several companies, including Tesla, SpaceX and xAI.
His wealth has changed at a very fast rate in 2026. In June, he became the first person to reach a trillion-dollar fortune, according to Forbes. That milestone did not last for long. His wealth later fell below that level as the value of SpaceX and Tesla changed.
Did Elon Musk Become the First Trillionaire?
Yes. According to Forbes, he became the world’s first trillionaire on June 12, 2026, after SpaceX became a public company.
However, this milestone should be understood carefully.
A trillion dollar net worth does not mean that he had one trillion dollars in cash. Net worth is an estimate of the value of assets after accounting for liabilities.
His wealth later fell below one trillion dollars as the value of SpaceX and Tesla changed. Forbes estimated his wealth at $690 billion on August 1, 2026.
Why Does His Net Worth Change So Fast?
A large part of his wealth comes from companies whose values can change. When the value of those assets rises, his estimated wealth can rise too. When their values fall, his wealth can drop.
This is why a billionaire can gain or lose billions of dollars on paper without receiving that amount as cash.
For example, Forbes reported that his fortune declined by about $363 billion in July 2026 after SpaceX and Tesla shares fell.
So, when you read that someone gained $10 billion in one day, it does not mean that person received $10 billion in a bank account.
SpaceX and Its Role in His Wealth
SpaceX has become a major part of his fortune. According to Forbes, SpaceX became a public company in June 2026. It opened trading at a valuation close to $2 trillion. Forbes reported that he owns about 38 percent of the company, including options.
This was a major event for his wealth.
Before this change, SpaceX had been privately held. Once the company went public, its value became measurable through its share price.
As a result, changes in SpaceX’s market value can have a major effect on his estimated wealth.
Tesla and His Business Empire
Tesla remains another major source of wealth.
He has led Tesla as its CEO since 2008. Forbes says he owns nearly 11 percent of Tesla.
However, his business interests are much wider than electric cars.
His companies and projects have included SpaceX, Tesla, xAI and X. Forbes also reports that SpaceX acquired xAI in February 2026 in a deal that valued the combined company at $1.25 trillion.
Therefore, his wealth now connects to several areas, including cars, space technology, artificial intelligence, and social media.
