PwC's August 2026 CEO survey reveals that AI adoption sentiment has shifted, with global revenue growth confidence rising to 42% (12-month outlook) and 51% (3-year outlook). However, only 39% of organizations report sustained positive AI impact, while 16% report negative returns. For Thai CEOs specifically, confidence is markedly lower (24% on revenue growth vs. global average), reflecting economic caution. The critical shift: AI must move from efficiency tool to strategic mechanism that connects early-warning signals to real business decisions—especially in cost management, demand forecasting, and identifying disruption-driven opportunities. Winners won't be those who invest most, but those who read markets and pivot fastest.
