DeepSeek Founder Liang Wenfeng Becomes World's Fastest-Growing Billionaire
According to a report by BestBrokers based on Forbes data, DeepSeek founder Liang Wenfeng's net worth surged by 3,850% in a single year, rising from $1 billion in 2025 to $39.5 billion in 2026. This explosive growth makes him the fastest-growing billionaire globally by percentage. This massive wealth accumulation highlights the immense financial impact of the AI boom, which has rapidly elevated founders of AI startups into the ranks of the world's wealthiest individuals. Conversely, it reflects shifting market sentiments, as legacy tech giants face scrutiny over heavy AI infrastructure spending. While Liang Wenfeng led in percentage growth, Elon Musk recorded the largest absolute wealth increase, adding $319.5 billion to reach a net worth of $725.1 billion. Meanwhile, Oracle CEO Larry Ellison suffered the largest wealth decline, losing $138.7 billion due to investor skepticism over the company's aggressive AI spending and rising debt.
