Cramer: Stocks say UK vote will be a ‘non-event’

Financial markets are leaning heavily toward thinking the United Kingdom will remain a part of the European Union, CNBC's Jim Cramer said Thursday.

"The stocks are telling that this is going to be a non-event," Cramer said on "Squawk on the Street."

Opinion polls taken before Thursday's vote indicated the outcome was too close to forecast, although two polls published late Wednesday suggested a swing toward remain.

Polls will close at 10 p.m. London-time (5 p.m. Eastern), and then the official returns are expected to start coming in around 1 a.m. Friday local time (8 p.m. Eastern). About 50 percent of the returns will be counted within the next three hours, according to most expectations.

U.S. equities jumped about 1 percent Thursday, while European stocks advanced more than 1 percent.

"They're going to stay, and we're going to be looking at the next thing," Cramer said.
