In laboratory asset markets, subjects trade shares of a firm whose profits in a linked product market determine dividends. Treatments vary whether dividend information is revealed once per period or in real time and whether the firm is controlled by a profit‐maximizing robot or human subject. The latter variation induces uncertainty about firm behavior, bridging the gap between laboratory and field markets. Our data replicate well‐known features of laboratory asset markets (e.g., bubbles), suggesting these are robust to a market‐based dividend process. Compared to a sample of previous experiments, both real‐time information revelation and endogenous uncertainty impede the bubble‐mitigating impact of experience.
