After the launch of Wall Street Journal’s Political Market (powered by intrade, coverage here and here) and CNN’s Political Market (powered by inkling), McCluskey and Hanson also debuted Presidential Decision Markets.

Today, Cowgill, Wolfers and Zitzewitz just released a full-fledged draft studying markets at Google, which is absolutely exceptional, definitely the most massive enterprise prediction markets application and study ever conducted! (coverage by the NY Times here.) I may return to comment further on this soon.

All of these in just 7 days. Who’s next? ;-)
