Wanna bet (on science)?: Several studies about corporate prediction markets mention the companies studied or those known to be testing prediction markets. See Cowgill, Wolfers, and Zitzewitz, “Using Prediction Markets to Track Information Flows.” Some studies also refer to some of the companies anonymously. For an example of a study doing both, see Cowgill and Zitzewitz, “Corporate Prediction Markets, Evidence from Google, Ford, and Firm X.” Both citations appear in the Selected Bibliography and Recommendations for Further Reading.
