Speaking at the Fortune Most Powerful Women Summit in Santa Barbara, she emphasized that these platforms create hostile environments. The vitriol directed at players significantly impacts their mental well-being and professional performance. ## Regulatory Loophole in Markets Platforms like Kalshi and Polymarket operate as financial exchanges rather than traditional gambling sites. This classification allows them to bypass standard sports betting regulations and restrictions. By positioning themselves as financial tools, these entities avoid the oversight typically applied to online sportsbooks, creating a unique regulatory gray area for athletes. ## Record Trading Volumes Reported Prediction markets are seeing massive growth, with Kalshi and Polymarket reaching a combined weekly volume of $22.2 billion last week. This surge is largely attributed to increased trading activity surrounding NFL and NCAA games. Such high financial stakes correlate directly with the rising intensity of harassment reported by professional athletes. ## Harassment Among College Athletes The 2025 NCAA study on student-athlete experiences reveals alarming trends regarding social media abuse. Over half of Division 1 men’s basketball players reported receiving online abuse linked to their performance. Notably, 46% of these athletes identified bettors as the primary source of the most threatening and negative messages they received. ## NBA and WNBA Response In response to growing concerns, the NBA and WNBA launched a responsible gaming campaign this Tuesday. They are partnering with the National Council on Problem Gambling to educate fans about the risks associated with sports betting. This initiative aims to address the behavioral consequences that stem from the intersection of gambling and sports. ## Limitations of Current Resources While the WNBA and the players association provide resources to mitigate abuse, Ogwumike notes these measures are insufficient. Many safety issues remain hidden from the public eye, preventing comprehensive solutions. Existing support systems struggle to stop the persistent harassment that continues to affect players' daily lives and their on-court performance. ## Performance and Safety Impact The psychological toll of targeted harassment directly influences how athletes perform during games. Ogwumike stressed that the current environment is not safe for professionals, as the pressure from bettors manifests in violent or abusive communication. This dynamic creates a barrier to maintaining a healthy and focused professional sports environment for all. ## Need for Further Mitigation Addressing the negative consequences of prediction markets requires more than just educational campaigns. Ogwumike advocates for increased efforts to protect athletes from the vitriol inherent in these high-stakes betting platforms. Without systemic changes, the intersection of financial speculation and sports will continue to jeopardize the safety of professional and collegiate athletes. ## Sources covering this story - https://fortune.com/2026/10/16/wnba-player-threats-prediction-market-users/ — --- _Summary written by Brifing from the original reporting.
