AI earnings face a bond-market speed limit
UGO13: How Much Longer Can AI Carry the Market ft. Christian Mueller-Glissmann
The episode examines whether AI-driven growth can withstand higher yields, debt-financed investment, cheap volatility, and a less predictable policy regime.
- 1AI earnings may remain durable, but investors have already priced in much of the expected growth.
- 2Higher yields and debt-financed investment could constrain the market even if technology companies keep delivering strong results.
- 3Cheap equity, bond, and FX volatility makes diversification more important than trying to time an elusive market peak.

Mueller-Glissmann rejects simplistic peak-timing and explains why diversification may be more reliable than predicting how geopolitical shocks hit markets.
The brief
Christian Mueller-Glissmann of Goldman Sachs joins Cem Arslan to assess whether AI-driven earnings can keep supporting markets as inflation and higher yields reshape the regime.
The central distinction is between an earnings bubble and a valuation bubble: technology profits may keep growing, but investors have already discounted much of that expansion.
Debt-financed AI investment raises the test for upcoming results: adoption must spread beyond the initial beneficiaries quickly enough to justify the capital cycle.
Market signals are unusually uneven, with subdued equity volatility alongside greater stress in credit, rates, commodities, and foreign exchange.
Rather than calling the peak, Mueller-Glissmann argues for diversification and disciplined allocation as politics, inflation, and policy intervention make old assumptions less reliable.
