Key Takeaways
  • • Kalshi Research hosted its inaugural Research Conference in late March 2026, signaling maturation of the prediction market industry with attendance from academics, Wall Street executives, former politicians, and professional traders.
  • • Sports trading reached nearly $3 billion in weekly volume at the time of the conference, representing approximately 80% of Kalshi's total trading volume, driven largely by March Madness activity.
  • • Sports trading's share of total volume hit an all-time low despite absolute volumes reaching record highs, indicating that non-sports prediction market categories are expanding faster than sports betting.
  • • Prediction markets have evolved beyond their initial perception as viable only during major election cycles and sports events; Kalshi has documented significant growth across multiple sectors beyond elections and sports.
  • • Global prediction market trading surged more than 400% year-over-year to nearly $64 billion, with industry projections suggesting potential growth to $1 trillion in annual trading by 2030.
Summary
The prediction markets industry reached an inflection point in March 2026, marked by Kalshi Research's inaugural Research Conference in New York. The event brought together a cross-section of institutional participants—academics, Wall Street executives, former politicians, and professional traders—reflecting what industry observers characterized as the sector's maturation from niche novelty to established financial vertical.

Co-founders Tarek Mansour and Luana Lopes Lara, speaking with Bloomberg's Katherine Doherty, outlined key dynamics reshaping the industry's composition and growth trajectory. A critical reframing emerged around the perception that prediction markets exist primarily for elections and sports betting. While major news cycles—including the 2024 election, Super Bowl, and March Madness—have historically dominated headlines and trading volumes, the underlying data reveals a more complex picture of sectoral growth.

At the time of the conference, sports trading had just reached nearly $3 billion in weekly volume, accounting for roughly 80% of Kalshi's total trading activity. However, the most significant metric was not the absolute volume but its relative share: despite sports hitting an all-time high in absolute terms, its proportion of total volume had contracted to an all-time low. This inversion indicates that every other market category—including non-election political events, financial outcomes, and other real-world forecasting categories—is expanding at materially faster rates than sports trading alone.

The broader market context underscores the scale of industry expansion. Global prediction market trading volumes surged more than 400% year-over-year to approximately $64 billion, with industry projections suggesting annual trading could reach $1 trillion by 2030. This growth has been facilitated by relaxed regulatory frameworks and increased platform accessibility, positioning prediction markets as a serious institutional forecasting and risk management tool rather than a seasonal or event-driven betting novelty.
