1. U.K. election jitters: The British pound was under pressure Wednesday after a new election projection showed that Prime Minister Theresa May could lose her majority in parliament.

Investors had been counting on a big win for May in the June 8 election, but the YouGov projection suggests that her party could lose a sizable number of seats. The result might be political gridlock.

Kallum Pickering, an economist at Berenberg Bank, said that unreliable polling data and an uncertain political landscape make the election result especially difficult to predict.

"To put it one way, we would not be very surprised if there was surprise!" he said.

The pound was trading 0.5% lower on Wednesday at just below $1.28. The currency has fallen 14% since the day of the Brexit referendum.

2. ExxonMobil meeting: Exxon (XOM) will hold its annual shareholder meeting on Wednesday, and climate change will top the agenda.

The event will feature a vote on a proposal that requires for Exxon to stress test its assets for risks posed by curbs on carbon emissions and new technology like electric cars.

The vote is seen as ground zero for efforts to get fossil fuel companies to acknowledge the ground is shifting beneath them.

3. Global market overview: U.S. stock futures were flat early on Wednesday.

European markets were mixed in early trading. Asian markets ended the session mixed.

The Dow Jones industrial average shed 0.2% on Tuesday, while the S&P 500 and Nasdaq declined 0.1%.
