How to use this
- The partners at the top of the table are the books worth keeping open next to Predict.fun: that is where discrepancies show up most often.
- A median life of 2.0 s means you need your stakes ready in advance; the calculator does the maths, and in the scanner card it is already done for you.
- The share of surebets lasting over a minute (6.6%) is what a browser notification from a background tab can still catch.
- An exchange does not limit players, but the volume at the price you need is capped by the order book; the scanner has a minimum-depth filter. More on the page about surebets with prediction markets.
FAQ
Why are some well-known books missing from the Predict.fun pairs? Either they share a feed (see the “Feed” row), or there were fewer surebets than the threshold in the window. The table is recalculated daily.
What is the median peak ROI? Each surebet records the highest ROI it reached during its life; the median is the value with half of surebets above it and half below. See the term ROI in the glossary.
Why are the numbers different from yesterday? The window is rolling, 30 days: tournaments, night hours and weekends change the picture. A snapshot for a specific date with the method is in the blog.
