Omnicom CEO John Wren just said the quiet part out loud: nobody’s actually priced AI yet.

The admission came on the holdco’s Q2 earnings call yesterday, in response to an analyst question on where AI is driving the biggest cost savings, and, more pointedly, whether those savings are flowing back into client marketing budgets or leaking out elsewhere. Wren’s answer focused less on savings and more on cost.

“The marketplace hasn’t seen what the cost of this AI is,” Wren said. “That’s going to weigh into the equation as well.”
