AI Bubble Debate: Economists vs. the Boom

Episode 1 · Apollo's Chief Economist Says AI Yields Zero Payoff Outside Tech, Sparking Debate (2026-10-25, 13 posts)

Torsten Slok, chief economist at Apollo, published a note in The Daily Spark—amplified by Bloomberg—that has become the focal point of the latest "AI bubble" debate: despite massive corporate spending on AI in the US, the technology has so far produced zero financial payoff outside the tech sector.

Confirmed

• Slok's core data: revenue per employee and profit margins keep rising for the Mag 7 but are flat for the S&P 493; productivity growth, including TFP near 0%, shows no improvement, leading him to expect limited macro impact from AI
• Slok also argues mainstream companies neither need nor will pay for the latest models, and—seeing no bottom-line benefit—have begun treating token spend as a margin-eroding cost center
• Gary Marcus shared the report on Oct 25, arguing the AI-skeptic case grows stronger daily and noting that even Sam Altman admits the problem is serious with no obvious fix
• Rohan Paul shared the report while listing counter-evidence against its bearish conclusion
• JHochderffer relayed investor Hossein Mohebbi's critique that the report's statistical methods are flawed and cannot support the zero-payoff claim
• Prediction market Polymarket lists "AI bubble bursts by year-end" at only 9%, suggesting markets do not expect an immediate unwind

Why it matters

• The report gives AI-bubble arguments heavyweight data support from a major financial institution's chief economist, moving the debate from opinion to corporate financial metrics
• If the Mag 7 vs. S&P 493 divergence persists, it will directly shape market views on the sustainability of AI capex; the opposing takes from Marcus, Rohan Paul and Mohebbi show skeptics and AI practitioners read the same data very differently
• Polymarket's low 9% odds indicate traders are not betting on an imminent bust despite the zero-payoff warnings

Episode 2 · Goldman, Apollo Warn AI Boom Nears Peak With Little Payoff Outside Tech (2026-10-27, 2 posts)

华尔街两大机构经济学家最新研判给 AI 热潮泼冷水。高盛首席经济学家 Jan Hatzius 认为 AI 对美国经济增长的拉动将在 2026 年末或 2027 年初见顶；Apollo 首席经济学家 Torsten Slok 则指出，AI 迄今未给科技行业之外的大公司带来任何利润改善，聚焦科技巨头之外的「S&P 493」企业，其财务回报几乎为零，质疑 AI 投资的广泛经济效益。
