Each event is compared on its lead outcome. Past co-movement is not a forecast. Moved together, moved opposite · Themes · Known limitations.
Over the past 30 days, the two markets’ 6-hour price changes (in log-odds) had a positive correlation that passed the checks; “opposite” means a negative one.
Not necessarily. A past correlation can vanish when news hits one market and not the other, and both can resolve against you.
With thousands of pairs tested, a few will pass by chance or through a shared driver that is not obvious. The false-discovery control limits this to an expected 5% or so, not zero.
Prices are the crowd’s estimates, not forecasts by Nimb, and nothing here is advice. Prediction markets are risky and you can lose your whole stake. Risk disclosure.
