This is a weekly read of what the largest hedge funds and asset managers are saying in public: letters, earnings calls and published outlooks. It paraphrases their views by asset class and links to the source. It is commentary on their commentary, not a view of my own on any security.
The short version: the big funds broadly agree on the risk and disagree on what to do about it. Several describe AI equities as bubble-like, but only some are positioned for a fall. Underneath the views, positioning is doing the talking.
By asset class
| Asset class | Who | What they said |
|---|---|---|
| Equities | Elliott (Paul Singer, Jonathan Pollock; October letter as reported) | Compares today with the speculative years before the Great Depression; warns crowded positions could unwind fast; hedged and holding cash. Says sentiment could flip from FOMO to 'fear of getting obliterated' |
| Equities | Citadel (Ken Griffin, 20 Oct) | Calls AI 'almost certainly' a bubble with uneven value capture, but is not betting against it long term |
| Equities | BlackRock Investment Institute (2 Nov) | Neutral on US equities; selective within AI, favouring infrastructure and bottlenecks; overweight emerging markets led by Asian chipmakers |
| Equities | Ray Dalio, Bridgewater founder (7 Oct) | Describes AI as a 'classic bubble' |
| Rates | BlackRock (2 Nov) | Expects structurally higher yields as AI investment competes for capital |
| Rates | Apollo (Torsten Slok, 15 Oct) | Rising inflation with weakening spending looks like stagflation; no recession call; Fed likely higher for longer |
| Rates | Pimco (Cyclical Outlook, October) | Constructive on high-quality intermediate bonds with yields near 20-year highs; likes inflation-linked bonds and commodities as protection |
| Credit | Pimco (October) | Selective; spreads are tight and AI-related credit risk may be underpriced |
| Credit | BlackRock (2 Nov) | Credit markets are the gauge of how much more AI spending can be debt-financed |
| Private credit | Apollo (Marc Rowan, Q3 results, 3 Nov) | Record origination; a mark-to-market loss at its insurer as rates stayed high |
| Private credit | Blackstone (Jon Gray, Q3 call, 22 Oct) | The feared private-credit losses have not materialised |
| Real assets | Blackstone (Q3 call, 22 Oct) | Compute demand accelerating with very tight supply; data-centre deals mostly long-term contracted; higher rates slow the property recovery |
| Multi-asset | Bridgewater (Greg Jensen, 14 Oct) | AI and 'modern mercantilism' reinforce each other; different markets are pricing different futures |

What the positioning says
Crowding, not valuation, is the near-term risk. PivotalPath estimates the ten largest multi-strategy firms run about $2.2 trillion gross on $360 billion of capital, and their US equity books overlap more with each other than with the rest of the industry. When the same holders share the same risk limits, a shock forces selling in the same names at once.
The de-grossing has started. Goldman's prime book showed the fastest hedge-fund tech selling in at least a decade in the week to 15 October; short positioning is near a five-year high; and fundamental long/short funds lost 2.9% in a week as the crowded AI trade unwound. Net leverage is down, but gross leverage remains high.
Private markets tell a calmer story than public ones. Apollo and Blackstone report record deployment and no wave of credit losses, while Elliott and Pimco flag AI-linked credit risk. Marks in private vehicles move slowly; listed proxies, such as business development company discounts, move first.
