Named investors called AI-era markets a bubble: Ray Dalio saw 'classic signs' of one reminiscent of 1929 and 2000 and agreed with Jeremy Grantham that this is 'the biggest investment bubble in American history'; Goldman Sachs's Peter Oppenheimer partly dissented — 'there does not appear to be a valuation bubble … there may be an earnings bubble' — while Apollo's Torsten Slok declared 'the 60/40 portfolio is broken.'

The speakers set no fixed date; this standing bubble call is tracked against its named indicator, the equity-issuance and IPO surge — SpaceX (public and trading below its first-trade price), Anthropic and OpenAI (both reported eyeing near-$1 trillion listings). The 2027-12-31 resolveBy is a charitable concrete reading, not the speakers' own. Unverified at capture.
