PwC's 21st CEO Survey asked 1,293 CEOs from around the world what's on their minds.
The rest of the world is cautiously optimistic, but North American CEOs never have been more sure of their companies' near-term prospects, according to the report. In 2017, only 39 percent reported that they were "very confident;" that number jumped to 53 percent in 2018. The report also ties North American confidence to the Trump economy.
The last time North American CEOs were this exuberant was in 2007 — the year before the global financial crisis.
