> What ends up happening is that people on these sites don't get any value from betting on events that are 90%+ likely. Sure they do. Even if you never reinvest your money and pay the entire withdrawal fee, it's still worth betting on a sure-thing when PredictIt is selling you dollars for 92 cents. This profitability threshold keeps increasing the more you're willing to stay on the site and let the money ride - a bettor on PredictIt can consistently get minor returns just betting on events that have essentially already happened. The $850 cap per market and research required make it a bit of a tedious endeavor, however, which is why there's still pennies to pick up so often.
