Notable price changes detected in the chart, along with research into what caused each movement.

📈 July 01, 2026: 28.0pp spike

Price increased from 21.0% to 49.0%

Outcome: Carlos Alcaraz

What happened: The primary driver of the 28.0 percentage point spike in Carlos Alcaraz's price for the 2026 ESPYS: Best Tennis Player market on July 1, 2026, was a surge in social media interest [^][^][^]. This activity coincided with the release of video footage showing Alcaraz resuming right-handed training after being sidelined by a wrist injury [^][^][^]. This positive development, indicating his recovery and potential return to form, likely improved sentiment regarding his chances for the award. Therefore, social media was a primary driver of this price movement.

📈 June 30, 2026: 20.0pp spike

Price increased from 1.0% to 21.0%

What happened: Based on the available information, there is no identifiable primary driver for the 20.0 percentage point spike in the "Carlos Alcaraz" outcome for the 2026 ESPYS: Best Tennis Player market on June 30, 2026.
