Will the S&P 500 ex-financials aggregate trailing-twelve-month operating margin reported for Q4 2026 exceed the Q4 2025 level by at least 50 basis points?

Broad AI adoption in administrative, support, engineering and coordination work lowers opex per unit of revenue fast enough that aggregate index-level operating margins expand by at least half a point year over year, rather than being reinvested into headcount.

Firms expand margins from AI

Firms route repeatable coordination, support, coding and back-office work to AI agents and owned or rented inference capacity, holding SG&A and R&D growth below revenue growth. Aggregate operating margin for the large-cap corporate sector steps up measurably, confirming that AI savings are harvested as margin rather than recycled into hiring.

AI savings get reinvested into growth, not harvested as margin

Firms that spend AI-driven efficiency gains on serving more customers rather than cutting headcount grow faster, so heavy adopters hire more across engineering and the functions AI was supposed to replace, keeping opex growth in line with revenue growth. Voice-based AI costs roughly as much per day as a human agent, making wholesale automation of customer-facing labor uneconomical in many cases and limiting the SG&A savings that could flow into margin. Under this view, aggregate operating margin in Q4 2026 comes in flat or lower versus Q4 2025 rather than stepping up by 50 basis points or more.
