Global equities markets seemed optimistic heading into the U.K. vote on its European Union membership, despite polls showing a neck-to-neck race, CNBC reports.

“I think the market’s already voted. … It looks like they’re looking for the stay vote to prevail,” Adam Sarhan, CEO of Sarhan Capital, said told CNBC.

In two surveys conducted June 21 and 22, the “remain” camp was shown to be in the lead, Bloomberg reports. Voters have until 10 P.M. London time, or about two more hours as of writing, to cast their ballot in the referendum. First results are expected around 7 P.M. New York time, with the final tally due at about 2 A.M. Friday.

“I think the market jumped the gun,” Gennadiy Goldberg, an interest-rate strategist at TD Securities LLC, told Bloomberg. “Today’s market move is what I would have expected from a ‘Remain’ win tomorrow.”
