Xavier Niel Net Worth

Xavier Niel has an estimated net worth of $14 billion, according to Forbes Real-Time Billionaires, Xavier Niel profile (figures as of October 20, 2026). That is up from $4.1 billion in 2019.

Xavier Niel is a French entrepreneur and investor best known for building Iliad, the telecom group behind Free. He founded Iliad in 1999 after earlier work in France’s internet business. Before that, Forbes notes that he started WorldNet in 1993 and that it was France’s first internet provider. He later exited that venture for $50 million. Over time, he became a major telecom owner in France and then expanded into other markets and investments.

His wealth comes mainly from telecom assets and a wider investment portfolio. Forbes notes that he owns Iliad, the parent of Free, one of France’s largest internet service providers. He also owns Monaco Telecom and Orange Switzerland, which he bought in 2014 for $2.9 billion and later renamed Salt. Beyond telecom, he holds stakes in Le Monde, Vodafone, and Unibail-Rodamco-Westfield. Forbes put his net worth at $14 billion on its real-time tracker as of October 20, 2026.

How Xavier Niel built his fortune

Niel’s money story starts with early internet access in France. Forbes says his WorldNet venture was the country’s first internet provider. He started it in 1993 at age 25 and later sold out for $50 million. He then built Iliad and launched Free, which became a major internet service provider. That gave him a large stake in the French telecom market and became the core of his wealth for years after.

His business later spread well beyond a single company. Forbes says he owns Monaco Telecom and Orange Switzerland, which he acquired in 2014 for $2.9 billion and renamed Salt. His portfolio also includes stakes in Le Monde, Vodafone, and Unibail-Rodamco-Westfield. Wikipedia background also notes that he launched Free Mobile in 2012, expanded into Italy in 2018, and that Iliad bought Play in 2020. Those moves widened his telecom reach across several markets.

Forbes net worth over time

Forbes valued Niel at $4.1 billion in 2019. That climbed to $8.9 billion in 2022, then dropped to $6.7 billion in 2023. By 2025, Forbes put him at $10.6 billion. Those changes fit a fortune tied to telecom and major equity stakes, including Iliad, Vodafone, Le Monde, and Unibail-Rodamco-Westfield. When the value of big holdings moves, a billionaire estimate can rise or fall with it.

The latest Forbes annual estimate is $14.6 billion in 2026, much higher than the figures from the earlier years listed above. Forbes also showed $14 billion on its real-time billionaires tracker in October 2026. His wealth is still centered on internet and telecom businesses, with Iliad at the heart of it. Ownership in operating companies and listed firms can shift in value, which helps explain why Forbes estimates have changed over time.
