In 2025, sportsbooks, financial platforms, and even media outlets like CNN partnered with existing markets or launched their own, further legitimizing the space. As shown in the chart, weekly notional volume has surged over the past year, with sports wagers accounting for the lion’s share of activity. With the Super Bowl just weeks away, spending on sports-related contracts is poised to hit record highs, underscoring how event-driven speculation is entering the mainstream. This momentum shows how prediction markets are moving toward widespread adoption, increasingly resembling structured markets where speculation meets investment.
