Historical Price (Probability)

Outcome probability
Date

The market experienced a massive 46.0 percentage point spike on July 14, lifting the contract's probability from a 1.0% floor to 47.0%. The provided information does not contain a specific catalyst for this initial repricing. This sharp increase established a temporary ceiling in the mid-40s before the contract's subsequent collapse.
On July 16, the price fell 43.0 percentage points, dropping from 44.0% back to 1.0%. This was a direct result of the match being suspended for rain during the third set. The suspension made a 2-0 victory for Bublik impossible, rendering the contract valueless. The 1.0% level has acted as a firm price floor, representing the market's assessment of a nullified outcome. The total volume of 19,301 contracts was concentrated around these sharp moves, indicating the market was not trading on evolving sentiment but reacting to a single, decisive news event that resolved the question.

📉 July 16, 2026: 43.0pp drop

Price decreased from 44.0% to 1.0%

Outcome: Alexander Bublik wins 2-0

What happened: The primary driver of the 43.0 percentage point drop was the interruption and non-completion of the Alexander Bublik vs. Quentin Halys match on July 16, 2026, due to rain [^]. The match was halted with Halys serving at 5-6 in the third set, confirming that a 2-0 victory for Bublik was not possible on that date [^]. This official update from the ATP Tour directly invalidated the prediction market outcome, leading to the significant price decline [^]. No social media activity was found to be a primary driver or contributing accelerant; based on the available information, it was irrelevant.

📈 July 14, 2026: 46.0pp spike

Price increased from 1.0% to 47.0%

Outcome: Alexander Bublik wins 2-0

What happened: The provided web research does not contain any information regarding social media activity, traditional news, or specific market structure factors that occurred on July 14, 2026, which could explain the 46.0 percentage point spike for the "Alexander Bublik wins 2-0" outcome.
