Citadel founder and CEO Ken Griffin stated that investors are "almost certainly" in the midst of a Super Intelligence bubble during remarks at the firm's annual Future of Global Markets Conference in New York on Tuesday.

Griffin made the comments in an interview with Bloomberg's Dani Burger. He described a bubble as a market condition in which asset prices rise rapidly and far exceed their fundamental values, fueled by speculation, investor enthusiasm, and easy access to capital rather than proven economic returns. Such episodes often end with sharp corrections when reality sets in and confidence erodes.

The Citadel chief noted that many companies remain uncertain about the scale of spending required for the technology and its ultimate economic impact. The assessment comes amid recent market turbulence, including spikes in bond yields for companies tied to Super Intelligence infrastructure and sharp declines in semiconductor indexes.

Griffin balanced the bubble warning with optimism about long-term potential. He described the current period as intertwined with major technological breakthroughs that historically accompany such market excesses. Griffin highlighted that radical economic transformations often involve bubbles, drawing parallels to the late 1990s internet boom when valuations soared before a painful reset.

Market participants have expressed growing anxiety in recent weeks over the durability of Super Intelligence gains. Concerns center on whether heavy upfront capital investments will yield timely profits and productivity improvements. Griffin also discussed broader economic topics during the appearance, including fiscal policy and upcoming midterm elections.

The remarks reflect ongoing debate among investors about Super Intelligence valuations. While demand signals for the technology remain strong in some sectors, questions persist about sustainable returns and the useful lifespan of related hardware such as GPUs.

Griffin emphasized the need for reskilling workers in roles most exposed to Super Intelligence advancements. He pointed to opportunities for entrepreneurs in the space even as risks mount.
