George Soros may be getting rich on an implosion in British markets — again.

The landmark vote in the U.K. to leave the European Union has rocked global markets, sending the British pound GBPUSD, +0.09% to its lowest level in more than 30 years. Futures for the Dow Jones Industrial Average DJIA, -0.87% plunged as much as 700 points at one point, and Europe’s benchmark stock index SXXP, -0.66% was facing its worst one-day plunge since 1987.

It is precisely the scenario of which Soros, writing in Britain’s Guardian newspaper last week, warned. The global financial carnage and Friday’s tumble could be adding to the wealthy investor’s bankroll, if reports are true.

Soros is famous for breaking the Bank of England — and lining his pockets — in 1992 with a bet against the British pound, which resulted in sterling’s ejection from the European exchange-rate mechanism.

Soros Fund Management, which manages some $30 billion for Soros and his family, has been scooping up gold assets and placing wagers that stocks will tumble, according to a Wall Street Journal report earlier this month.

In early electronic trade Friday, gold futures US:GCQ6 stampeded to their highest level in two years. Although they’ve cooled somewhat, the yellow metal was still at $1,328.20 an ounce. It has drawn safe-harbor bids due to investors’ worries that the so-called Brexit, as a British exit from the EU has come to be known, could destabilize Europe’s trade bloc.

Soros bought some 19 million shares in gold miner Barrick Gold Corp. US:ABX in the first quarter, according to recent public filings. He also bought a large stake in the silver-focused mining operation Sliver Wheaton Corp. US:SLW.

And Soros may not be the only prominent investor making out like a bandit.

Duquesne Capital’s Stanley Druckenmiller, a former Soros associate, and Paul Singer, head of the hedge fund Elliott Management, have been advocating buying gold to guard against market shocks.

Soros’s exact positioning isn’t known because his public fillings only offer a snapshot of his long investments. The SEC requires any institutional investment manager with positions of at least $100 million to reveal all long stock positions held at the end of each quarter.
