Prediction Markets Hit $28 Billion as States Test Federal Control of U.S. Gambling

Prediction markets have soared to $28 billion in value, driven by a surge in wagers on sports such as the NFL and NBA. As bets skyrocket—more than $6 billion in December alone—states are challenging federal control over the gambling industry.

Key Takeaways:

  • U.S. prediction markets reached a total of $28 billion.
  • More than $6 billion was moved in just one month (December).
  • About 70% of bets come from major sports events.
  • States are testing federal authority over gambling.
  • Platforms like Kalshi and Polymarket are pivotal to this growth.

The Rise of Prediction Markets

U.S. prediction markets hit a notable milestone, surging to a combined $28 billion in total value. According to data from The Block, December was particularly lucrative, with Kalshi and Polymarket together moving over $6 billion in that month alone.

Sports Betting’s Influence

The popularity of sports wagers remains a key driver in this arena, with approximately 70% of bets coming from events like the NFL and NBA. Big games, including major championships and playoff matchups, reportedly draw the largest share of activity, showcasing how sports-driven enthusiasm fuels a considerable portion of the market’s growth.

State vs. Federal Oversight

Even as wagers climb, so do questions about gambling regulations. States are increasingly exploring their own rules for hosting wagers, which puts them on a collision course with federal authorities. Whether federal agencies will tighten their grip or allow states more leeway remains to be seen, but the ongoing regulatory tension is poised to shape the market’s next phase.

Market Players at the Helm

Kalshi and Polymarket have emerged as key forces behind this expansion. By collectively handling billions of dollars in December, these platforms underscore the public’s appetite for prediction markets. Their continued innovation could further propel the industry’s metrics, influencing how both casual and experienced bettors approach the market.

Future Considerations

As the U.S. prediction market charges ahead, observers wonder just how high these figures can climb. The tug-of-war between state autonomy and federal oversight will likely dictate the pace of innovation. With multi-billion-dollar monthly flows in sports betting alone, industry analysts are watching closely to see how rules evolve—and whether the $28 billion milestone signals the beginning of even greater shifts in American gambling.
