What does 40.0% mean?
The market is currently pricing the Before 2027 outcome at about 40.0%: a contract that pays $1 if the market resolves that way costs roughly 40.0% of its payout to buy. That number is the market-implied probability, the aggregated judgment of traders with money at stake, not a forecast by PredictionBubbles.
When the price moves, the market has repriced the question. The 24-hour figure on this page is that move in probability points, not percent. Markets can be early, late or wrong; what keeps the number honest is that anyone who disagrees can trade against it.
