Simon Nixon Net Worth

Simon Nixon has an estimated net worth of $2.1 billion, according to Forbes Real-Time Billionaires, Simon Nixon profile (figures as of October 20, 2026). That is up from $1.1 billion in 2019.

Simon Nixon is a British entrepreneur best known for helping build MoneySuperMarket. He cofounded the business in 1993 with Duncan Cameron while he was still a student at the University of Nottingham. It began as Mortgage 2000, giving off-line mortgage information to independent financial advisors. In 1999, the company launched moneysupermarket.com and moved online, later adding credit card and personal loan information as the business grew.

Most of Nixon's fortune came from MoneySuperMarket, according to Forbes. The company went public in 2007, and he sold all his shares by 2016. After that, he kept backing private companies, including Airbnb, Robinhood and Wise before they went public. He also runs Simon Escapes, a luxury holiday rental site built around homes he owns in places such as Malibu and Barbados. Forbes put his wealth at $2.1 billion in October 2026.

How Simon Nixon built his wealth

Nixon made the bulk of his money from the price comparison website MoneySuperMarket, Forbes says. He started the business in 1993 with Duncan Cameron, first serving financial advisors with off-line mortgage information under the name Mortgage 2000. A few years later, the company launched online and expanded beyond mortgages. It added areas such as credit cards and personal loans, turning a narrow service into a broader consumer finance platform.

His money story did not stop with one company. Forbes says he took MoneySuperMarket public in 2007 and had sold all his shares by 2016. He then invested in dozens of private companies, including Airbnb, Robinhood and Wise before they went public. Nixon also owns luxury homes around the world and rents some of them through Simon Escapes, his holiday rental site with listings in destinations including Malibu and Barbados.

What Forbes says about his net worth

Forbes placed Nixon at $1.1 billion in 2019, then $1 billion in 2020. The estimate later rose to $1.2 billion in 2021 and $1.4 billion in 2022. By 2023, Forbes had him at $1.9 billion, followed by $2 billion in 2024. Those changes fit the picture of a founder whose wealth came first from a public internet business and later from a wider portfolio of private investments and property.

The latest Forbes figure is $2.1 billion on its real-time billionaires tracker as of October 20, 2026. Forbes also listed him at $2.1 billion on the 2026 World's Billionaires List. Its profile notes point to the same main engines behind that estimate: the fortune he built from MoneySuperMarket, his stakes in private companies, and his property holdings, including homes used for private holiday rentals through Simon Escapes.
