Russian billionaire Mikhail Prokhorov is reportedly looking for a buyer for the NBA basketball team he bought five years ago, amid speculation that the his country’s shrinking economy may have squeezed his finances.

The 49-year-old businessman, worth roughly $11.1 billion, wants to unload the Brooklyn Nets, Bloomberg reports. A spokesman for Prokhorov told Bloomberg that the team is open to sale offers.

There are many reasons that Prokhorov, the first foreign owner of an NBA team, could be considering a sale. The team has suffered a dismal start to the season after a poor record last year, sinking his plans for a spot in the championships within five years. The team has also lost about $144 million in the last year, according to ESPN.

The billionaire may also be capitalizing on an apparently hot market for NBA teams after former Microsoft CEO Steve Ballmer bought the Los Angeles Clippers last year for a record $2 billion. The Nets have been valued at around $1.3 billion, which means a sale could net Prokhorov nearly $1 billion in profits from his original, $220 million stake.

But as the Russian economy crumbles under falling oil prices and tough Western sanctions, the nation’s business elite are feeling the pressure. Last month alone, Russia’s richest 20 people — Prokhorov included — lost a combined $10 billion as the value of the ruble tumbled. They lost a combined $62 billion across the year, according to the analysis by Bloomberg.

And Prokhorov’s not alone. Russian billionaires have snapped up marquee items in Europe and the U.S., from sports teams to properties. There are growing fears that the downturn in Russia may prompt some of them to sell off their properties to cover losses.
