Elon Musk has taken another step toward becoming the world's first trillionaire.

According to the latest data from Forbes, his net worth has reached $677 billion (approximately 4.78 trillion yuan), making him the first person in history to surpass a net worth of $600 billion—no one has previously reached the $500 billion threshold.

This leap is primarily due to the significant increase in SpaceX's valuation. Earlier this month, SpaceX initiated a share buyback, pushing the company's valuation to $800 billion (approximately 5.65 trillion yuan), doubling from $400 billion in August this year. Musk owns about 42% of SpaceX, and this valuation increase has added approximately $168 billion to his personal wealth. As of noon on Monday Eastern Time, his net worth officially rose to $677 billion.

SpaceX is preparing for its IPO in 2026, at which time its valuation could reach $1.5 trillion, and if achieved, it will directly propel Musk into the trillionaire ranks. Currently, SpaceX shares have become Musk's most valuable asset, worth approximately $336 billion, surpassing his 12% stake in Tesla (approximately $197 billion, excluding disputed options).

In the past five years, Musk has created multiple wealth records:

•March 2020: Net worth was only $24.6 billion;

•August 2020: Tesla's stock price surged, becoming the fifth person in history to surpass $100 billion;

•January 2021: Ranked as the world's richest for the first time with nearly $190 billion;

•September 2021: Third person to exceed $200 billion (the first two were Bezos and Arnault);

•November 2021: Surpassed $300 billion;

•December 2024: Surpassed $400 billion;

•October 2025: Surpassed $500 billion.

Now, Musk leads the second richest by over $400 billion, with an unprecedented wealth growth rate, largely relying on the soaring valuations of Tesla, SpaceX, and xAI among other enterprises.
