There are several prediction markets that allow legal wagers on political, economic, technological, ..., events.
The Wikipedia page at - en.wikipedia.org/wiki/Prediction_market - lists and describes them: "Prediction markets (also known as predictive markets, information markets, decision markets, idea futures, event derivatives, or virtual markets) are speculative markets created for the purpose of making predictions. The current market prices can then be interpreted as predictions of the probability of the event or the expected value of the parameter. For example, a prediction market security might reward a dollar if a particular candidate is elected, such that an individual who thinks the candidate had a 70% chance of being elected should be willing to pay up to 70 cents for such a security. People who buy low and sell high are rewarded for improving the market prediction, while those who buy high and sell low are punished for degrading the market prediction. Evidence so far suggests that prediction markets are at least as accurate as other institutions predicting the same events with a similar pool of participants...." High profile media have covered LENR. Would a prediction market in LENR also attract enough participants to be liquid? Perhaps with a wager like - 'A Fortune 500 company announces an LENR product by 2015'?
