As of April 2020, his net worth is estimated at US$6.7 billion.

In 2014, Cable & Wireless Communications (CWC) sold its 55% economic interest in Monaco Telecom to NJJ Capital, an investment vehicle controlled by Xavier Niel for US$445 million.

In 2013, Niel created a school named 42, which is a free tech school with no teachers, no books, no tuition for 1000 people every year.

Xavier Niel born in a middle class family, his father is a jurist in a pharmaceutical laboratory, and his mother is an accountant. He studied in the 12th arrondissement of Paris at the Saint-Michel-de-Picpus Catholic private high school.

In 2012, he created Free Mobile, which revolutionizes mobile telephony in France, with a 25 US$ plan, including unlimited voice calls, text and data (3G/4G).

In March 2010, Xavier Niel cofounded with Jeremie Berrebi Kima Ventures, a fund dedicated to invest in 50 to 100 startups a year everywhere in the world. Kima Ventures already invested in 330 companies from February 2010 to August 2014 in 32 countries. Business Insider described Xavier Niel and Jeremie Berrebi as almost certainly the most active angel investors in the world.

In late 2010 Niel was a member of a group of investors which acquired a controlling stake in the newspaper Le Monde.

On 28 May 2004, Xavier Niel was indicted and detained for a month for alleged procuring and misuse of company assets, which occurred in several sex shops in which he was a shareholder. On 30 August 2005, a Nolle prosequi was pronounced for the procuring part of his indictment, while on 13 October 2006, he was given a 2 years suspended prison sentence for the misuse of company assets.

In 1999, he created Free, a French Internet service provider. The name came from the fact that modem access was really free, which caused some stir among other (non-free) French Internet providers, as well as it raised some questions about Free's business model. In 2002, Free launched a broadband package at a low price (€29.99 per month), which became the benchmark in the market. At the same time, Free developed and launched the Freebox: the first triple-play multi-service box in France. The free modem service had brought to the company a strong potential customers portfolio, many of them switching to the broadband for the sake of comfort.

In 1999, he founded Online, a French hosting company.

After taking over a company subsequently renamed Iliad SA, Xavier Niel launched in 1996 the 1st reversed directory service on the Minitel. This service was responsible for 1 million euros of revenue per year for Iliad until the end of the minitel in France in 2012. Niel remains Iliad's majority shareholder, holding 63.93% of the share capital.

In 1995, he invested in the first Internet Service Provider in France, World-NET, created the previous year by Sébastien Socchard, Philippe Langlois and Pierre Séguret. This company was sold the year before the internet bubble burst.
