Why
- The market says 42%, and it's well traded, so it gets most of the say
- Things like this happen about 35% of the time, by our estimate, which pulls us down 2 points
- The market swung between 42% and 79% over the past month, so we allow a wide range
The range
In 9 of 10 simulations, the chance lands between 14% and 74%.

How we got this number
- We start from the Polymarket price (42%) and blend in a base rate of 35% on the log-odds scale. Here the market carries 78% of the weight: a deep, fresh market earns more, a thin or stale one less.
- Why 35%: the arena crown changes hands most quarters; with three labs in contention, 35% is the forecaster's judgment call.
- Then we run 40,000 simulations. Their spread comes from how far the market moved over the past 30 days, the time left, and a small shock shared by every question (news that moves many markets at once). Our number is the middle of the runs (the median); the range is the middle 90%.
- One-off questions can't be backtested, so the ranges are wide on purpose. We grade every question when it resolves.
