Predict tomorrow, today. Join scientists, engineers and technologists from around the world in the largest collaborative science and technology forecasting effort, ever. This is your opportunity to make real-time predictions on future innovations and significant events in science and technology. Show off your mental prowess with forecasts in topics that interest you. Earn recognition when you’re correct. Publish your own questions and access prediction market trading data for your personal research. Sign up at www.SciCast.org. SciCast is a combinatorial prediction market, enabling probabilistic forecasts that can depend on assumptions about the outcomes of relevant events. Market forecasts are updated in real-time using state-of-the-art computational Bayesian inference techniques. You can also participate in online experiments that compare different forecasting techniques. This is a non-profit federally-funded research project run by George Mason University. We will never expose or share your personal data.
