Understanding Implied Probability on Polymarket

When you look at Polymarket odds, you're essentially seeing an implied probability, similar to how options pricing reflects probability. If a market shows 'Yes' at 0.75, that means the market is pricing in a 75% chance of that event occurring. This is derived directly from the last traded price. A 'No' at 0.25 on the same market means a 25% chance.

Now, the crucial part for your trading edge is comparing this implied probability to your own assessment of the true probability. If you believe the real probability of the 'Yes' event is 85%, but the market is only offering 75% implied probability, you might have an edge. Conversely, if you think the event has a 60% chance, but the market is at 75%, it's likely overvalued from your perspective. This divergence between market-implied probability and your analysis is where profit potential lies, much like finding mispriced assets in traditional markets. Always calculate your expected value.
