The newest integration with the Interactive Brokers Prediction Market includes contracts settled through Kalshi and the CME Group in addition to ForecastEx. This Thursday’s initial unemployment claims print provides an example of an indicator listed by two different exchanges with ForecastEx preceding each threshold with “above,” while Kalshi uses “at least” before the statistic. The simple difference amongst the trade opportunities is that the former must arrive ahead of the number chosen to be profitable while the latter can come in equal to the figure to pay out $1.00. Additionally, the spreads across the venues can vary significantly, as you can see below, offering potential arbitrage possibilities for participants. Overall, though, this June 4 release is expected to land between 210k and 220k, which is in the same ballpark as the 213k median estimate in the monthly Reuters poll of 39 forecasters who have minimum and maximum projections of 205k and 225k.
