(This is my top web page on idea futures. Go here to find my publications on idea futures.)The Idea Our policy-makers and media rely too much on the "expert" advice of a self-interested insider's club of pundits and big-shot academics. These pundits are rewarded too much for telling good stories, and for supporting each other, rather than for being "right". Instead, let us create betting markets on most controversial questions, and treat the current market odds as our best expert consensus. The real experts (maybe you), would then be rewarded for their contributions, while clueless pundits would learn to stay away. You should have a free-speech right to bet on political questions in policy markets, and we could even base a new form of government on idea futures.
One can subsidize a market on a question, offering extra rewards to those who bet right on this question. This subsidy is an "information prize", offered to those who first provide information on a question, in contrast to an "accomplishment prize", given to those who first accomplish some task. Instead of patronizing academic basic research via proposal peer-review, we should use prizes more.
Publications Idea Futures has been described in many publications by myself and others, including both academic journals and popular media.
Web Games There are many web sites which let one bet on sports, but the Foresight Exchange (FX, previously called Idea Futures) was the first general web betting game, and was the first to allow users to introduce new claims to bet on. Begun by Sean Morgan, it won the 1995 Prix Ars Electronica Golden Nica for world's best web site. Over 1500 players now bet play money on over 200 questions of their choosing. Check out the current betting odds, an independent 'Zine, and m o r e. The game's developers once formed a business, Ideosphere (now wholely owned by Kumo Software) that now seems defunct. Recently other play-money markets have appeared, such as Hollywood Stock Exchange, Invisible Hand Electronic Market, Fanatasy Futures, and NewsBet. (I have no relation with or stake in any of these ventures.) I think the odds in these markets are often too optimistic, but they do pretty well considering, and a real money market would do much better.
(Another web market, Java Idea Futures, isn't really an Idea Future in the above sense; they trade perhaps-not-yet-written Java Applets.)
To get an Idea Futures market approved as a security in the US, you'd need CFTC approval. But they require expensive review, require you to set up a physical pit for trading there, and are sure that there is no point to markets where there is not substantial hedging demand. (Respected academics can sometimes get exceptions though.)
Betting is illegal in most of the world (including Nevada), with exceptions carved out over the years by special interests, such as for horse bets, lotteries, and casinos. Only the UK, to my knowledge, allows non-sports betting. Some off-shore gambling places are now soliciting folks citizens to bet with them by phone (e.g., 1-800-I-CAN-BET) or internet (e.g., Internet Casino). It will be interesting to see how strongly U.S. police and legislators react to discourage U.S. citizens using the web to bet in these foreign markets. See also these discussions of legal issues.
Close, but not enough
