This year, the combined wealth of the world's more than 3,100 billionaires increased by $3.6 trillion from the beginning of the year, reaching a total of $18.7 trillion. Elon Musk's pursuit of a trillion-dollar net worth is no longer just talk; at the beginning of the year, his net worth was $421 billion, and by October he became the first person in history to surpass $500 billion, making him arguably the biggest winner of the year. His net worth increased by over $333 billion throughout the year, equivalent to an increase of $935 million per day. Most global stock markets performed well in 2025, driving up the wealth of the super-rich. The S&P 500 index returned 17% for the year, while major stock indices in Germany, Japan, and Canada performed even better, with gains of 22%, 26%, and 30% respectively. Of course, compared to others, some billionaires fared even better: the ten biggest winners, already incredibly wealthy, saw their net worth surge by over $729 billion in the past year. Of the top ten wealthiest individuals, six are American billionaires, accounting for over 85% of the total wealth increase. This data clearly shows that a new wave of wealth creation is highly concentrated in this country governed by a billionaire president and whose cabinet members are all extremely wealthy. With surging investment in artificial intelligence and the US striving to gain a leading position in the AI race, the top five wealthiest individuals this year are all giants in the American tech industry.
