Who is Zhang Yiming, Chinese tech billionaire now richer than Mukesh Ambani?

For years, Mukesh Ambani was the face of Asian wealth. His rise mirrored India's economic growth, telecom revolution and consumer boom. But this week, the billionaire rankings got a surprising shake-up.

A software engineer who started a company from a modest apartment in Beijing has overtaken Ambani to become Asia's second-richest person.

His name is Zhang Yiming, the founder of ByteDance, the company behind TikTok.

According to the Bloomberg Billionaires Index, Zhang's net worth has climbed to $92.8 billion, pushing him ahead of Ambani, whose wealth is estimated at $86.9 billion. Only Gautam Adani, with a fortune of $117.4 billion, now stands above him in Asia's rich list.

FROM A SMALL APARTMENT TO A GLOBAL TECH EMPIRE

Born in Longyan in China's Fujian province, Zhang's story does not begin in a luxury boardroom. Unlike many billionaire founders who dropped out, Zhang completed a degree in Software Engineering from Nankai University, one of China's leading universities.

During his college years, he developed a strong interest in technology and programming, skills that later helped him shape ByteDance's AI-driven approach, which became the backbone of products like Toutiao and TikTok.

He went on to work at several technology firms, including Microsoft. Like many tech entrepreneurs, he saw an opportunity where others saw a crowded market.

In 2012, he launched ByteDance from a small apartment in Beijing.

His original idea was simple but powerful: use artificial intelligence to understand what people want to read, watch and consume online. The company's first breakthrough came with Toutiao, a news recommendation platform driven by algorithms rather than traditional editors.

That AI-first thinking would later help create one of the world's biggest digital products.

THE APP THAT CHANGED SOCIAL MEDIA

ByteDance's biggest success arrived with TikTok.

The short-video platform exploded across the world and today serves more than one billion users. It reshaped entertainment, marketing, music promotion and even news consumption.

For millions of young users, TikTok became not just an app but a daily habit.

The platform's success transformed ByteDance into one of the world's most valuable private technology companies and turned Zhang into one of the richest entrepreneurs on the planet.

AI IS NOW MAKING HIM EVEN RICHER

TikTok may have built Zhang's fortune, but artificial intelligence is now accelerating it.

ByteDance's AI chatbot Doubao has emerged as one of China's most popular AI products, reportedly attracting more than 300 million monthly users.

Investors are increasingly viewing ByteDance not only as a social media giant but also as a serious AI contender.

That confidence has had a direct impact on Zhang's wealth.

Bloomberg estimates that his fortune jumped by more than $24 billion after updated company valuations from major investors such as BlackRock, Fidelity Investments, T Rowe Price and General Atlantic.

The company is reportedly considering spending as much as $70 billion this year to strengthen its AI capabilities and compete with major American technology firms.

WHY INVESTORS ARE BETTING BIG ON BYTEDANCE

Another factor boosting ByteDance's valuation is improved confidence about TikTok's future in the United States.

For years, fears of a possible US ban weighed on the company's valuation. Recent restructuring efforts and greater involvement from US-based investors have eased some of those concerns.

At the same time, ByteDance's financial performance remains extraordinary. The company reportedly generated around $50 billion in profit during 2025, giving it immense resources to fund ambitious AI projects.

For investors, the message is clear: ByteDance is no longer just the company behind TikTok. It is becoming one of the world's biggest AI players.

A SIGN OF HOW WEALTH IS CHANGING

The rise of Zhang Yiming says something bigger about today's economy.

A generation ago, Asia's richest people often built fortunes in oil, real estate, manufacturing or infrastructure. Today, software, algorithms and artificial intelligence are creating wealth at an unprecedented pace.

Zhang stepped away from day-to-day management years ago. Yet the company he built continues to grow, and so does his fortune.

From a small Beijing apartment to a $93 billion fortune, his journey is a reminder that in the AI era, the next billionaire may not own factories or oil fields. They may simply own the algorithm everyone uses every day.
