EY exec: only 10% of clients can show real AI ROI

EY executive Dan Diaso said businesses are still not seeing substantial revenue gains or cost cuts from AI. Only one in 10 of EY's clients can actually show where the ROI is happening, even as AI spending keeps growing on enthusiasm rather than evidence.

• Only 1 in 10 EY clients can show AI ROI in their income statements
• AI spending is still driven by enthusiasm, not evidence of returns
• Usage-based pricing from Anthropic and others led to much higher bills
• Companies use AI tools more carefully and adopt open source models more
