The annual Allen & Co conference, gathering some 300 media and tech CEOs, plus some of the most powerful investors in the world, comes on the heels of a shocking vote in favor of a Brexit.
With the markets on a roller coaster in the wake of the U.K's decision to exit the European Union (EU), CEOs at Sun Valley are evaluating the potential implications for their businesses and the economy as a whole.
WPP CEO Sir Martin Sorrell says there's no question that the vote is bad for the economy.
"On the question of the economy I think even the leavers thought it was best to stay in," says Sorrell in an interview on CNBC. But Sorrell is optimistic that "the game's not over yet," with another two-year negotiation period to start when Article 15 is triggered.
