Slok says AI has no payoff outside tech; DeLong challenges his measure

Case period:

Published by The Dispute Index editorial teamPublished Updated

Overview

Torsten Slok says AI has delivered no financial payoff outside tech, citing revenue, margins and productivity measures. Brad DeLong accepts the flat corporate series but argues that user benefits and new firms may matter more. He also questions whether those benefits justify current valuations.

Read the full background

On October 24, 2026, Apollo chief economist Torsten Slok argued that AI's payoff should be judged by whether it improves revenue and margins beyond the largest technology companies. His charts compare the Magnificent Seven with the other 493 S&P 500 companies, which are not a pure sample of nontechnology businesses.

Brad DeLong responded the same day. He accepts that the cited revenue and margin measures are flat, but argues that benefits reaching users, new businesses and changes in platform power are important channels that those measures miss. He remains skeptical that these channels justify current market valuations.

The disagreement concerns what the measures can establish about AI's economic payoff. It is not a disagreement over a rival profit series or an unqualified claim by DeLong that AI has already produced a broad productivity boom.

    Why this label?

    The case scrutinizes Slok's interpretation of AI payoff. He expressly endorses that same interpretation and argues for the S&P 493 as its test, which is defense of the position under scrutiny.

    This label describes the statement's response within the context above.

  2. Brad DeLongEconomist responding in his own newsletterDirectly involved

    Full statement and sources

    Torsten Slok Beats the AI-Bear Drum: Charts of the DayDeLong's own user-surplus discussion after the Slok quotation

    Why this label?

    The case scrutinizes Slok's interpretation of payoff. DeLong challenges the yardstick, rather than its profit figures. Agreement on those figures does not endorse the interpretation; his valuation doubts are a separate assessment.

    This label describes the statement's response within the context above.
