Historical Price (Probability)

Outcome probability
Date
The price chart for this market shows a dramatic upward trend, characterized by a single, massive price spike on May 14, 2026. The market opened with a YES probability of just 1.0% but surged 68 percentage points to a high of 70.0% within the same day. The current price is stable near this peak at 69.0%. The provided context indicates that there is no identifiable news, social media activity, or other market factor that explains this sudden and significant re-pricing of the odds in favor of Mateo Del Pino.
Total trading volume is low at 88 contracts, suggesting a relatively thin market. Notably, volume was nonexistent at the initial low price levels, with trading activity only appearing as the price reached its peak. The volume of 18 contracts at the 69.0% level indicates some market participation and conviction at this new, higher probability. The key price points are the floor at 1.0% and the current plateau around 69.0-70.0%. This price action suggests a sudden and decisive shift in market sentiment, moving from viewing Del Pino as a near-certain loser to a strong favorite. The lack of a clear catalyst for such a drastic change is the most defining characteristic of this market's behavior.
