While traditional sports betting is restricted in many areas, prediction markets like Kalshi are often regulated as commodity markets. This arbitrage allows them to legally offer wagering on sports outcomes in most states, effectively operating as back-door sportsbooks and reaching a national audience.

The explosive growth of prediction markets is driven by regulatory arbitrage. They capture immense value from the highly-regulated sports betting industry by operating under different, less restrictive rules for 'prediction markets,' despite significant product overlap.
New platforms frame betting on future events as sophisticated 'trading,' akin to stock markets. This rebranding as 'prediction markets' helps them bypass traditional gambling regulations and attract users who might otherwise shun betting, positioning it as an intellectual or financial activity rather than a game of chance.
Kalshi argues its market-based system for sports events is superior to traditional sportsbooks because anyone can be a price maker, not just a price taker. This results in better odds and a user win/loss ratio closer to 50/50, framing it as an equitable financial market rather than a house-always-wins model.
Though functionally similar to users, prediction markets and sports betting operate under different regulatory frameworks. Prediction markets are lightly regulated by the federal government, while sports betting is heavily regulated state-by-state. This distinction allows prediction markets to legally operate in jurisdictions where sports betting is banned, fueling rapid growth.
While often promoted as tools for information discovery, the primary business opportunity for prediction markets is cannibalizing the massive sports betting industry. The high-volume, high-engagement nature of sports gambling is the engine to acquire customers and professional market makers, with other "informational" markets being a secondary concern.
Prediction markets have existed for decades. Their recent popularity surge isn't due to a technological breakthrough but to success in legalizing them. The primary obstacle was always legal prohibition, not a lack of product-market fit or superior technology.
Kalshi’s key strategic move was getting its prediction markets regulated by the federal CFTC, similar to commodities. This established federal preemption, meaning state-level laws don't apply. This allowed them to operate nationwide with a single regulator instead of seeking approval in 50 different states.
While gaining traction, prediction markets are on a collision course with regulators. Their expansion into domains resembling sports betting is unsustainable without government oversight and revenue sharing. The current "lawless" phase, where they claim not to be gambling, is unlikely to last, leading to a stalled 2026.
After a long regulatory battle, Kalshi expanded its event marketplace through a series of 'small p pivots.' They started with current events, moved to economic indicators, then elections (which required suing their regulator), and now sports. This shows a methodical approach to market expansion in a regulated space.
Donald Trump's idea to eliminate taxes on gambling winnings has an overlooked nuance. Due to an existing tax law that limits deducting gambling losses, professional bettors on sportsbooks are disadvantaged. Making winnings tax-free would disproportionately benefit traders on prediction markets where losses can be fully deducted, shifting activity to those platforms.
