British-Nigerian boxing champion Anthony Joshua has built a business empire valued at more than ₦309 billion, according to newly released financial records ahead of his return to the ring.

Joshua’s company, Sparta Promotions Ltd, has been valued at £166.06 million, which translates to approximately ₦309.8 billion based on the current official exchange rate between the pound and naira.

The company’s latest accounts for the financial year ending March 2025 showed that Sparta Promotions recorded a turnover of £41.5 million and posted a pre-tax profit of £35.7 million after expenses.

The financial statement also revealed that the company maintained cash reserves of about £36.3 million, worth roughly ₦67.7 billion, alongside investments valued at £8.8 million, estimated at about ₦16.4 billion.

Joshua’s growing business portfolio comes as the former heavyweight champion prepares for his return to professional boxing against Albanian fighter Kristian Prenga in Saudi Arabia next Saturday.

The 36-year-old has remained one of boxing’s biggest global attractions since winning Olympic gold at the 2012 London Games and later becoming a two-time unified heavyweight world champion.

The latest financial figures were released before the fatal road accident in Nigeria last December that claimed the lives of two of Joshua’s close friends.

Joshua survived the crash and received medical treatment for injuries sustained during the incident.

His upcoming bout against Prenga marks his return to competitive action after a period away from the sport and is expected to launch his attempt to rebuild momentum in the heavyweight division.

The comeback has also renewed talks of a potential blockbuster fight against fellow British heavyweight Tyson Fury, with boxing supporters continuing to hope for a meeting between the two former world champions.
