The primary challenge for prediction markets comes from state governments protecting their lucrative sports betting monopolies. States earning billions in tax revenue are unlikely to allow unregulated prediction markets to siphon off that business. This creates a powerful financial incentive for a state-level crackdown, a more immediate threat than federal oversight.

This distinction allows prediction markets to legally operate in jurisdictions where sports betting is banned, fueling rapid growth.
Prediction markets are cannibalizing the traditional gaming industry by framing gambling as an intellectual activity.

While often promoted as tools for information discovery, the primary business opportunity for prediction markets is cannibalizing the massive sports betting industry.

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.

While praised for aggregating the 'wisdom of crowds,' prediction markets create massive, unregulated opportunities for insider trading. Foreign entities are also using these platforms to place large bets, potentially to manipulate public perception and influence political outcomes.
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.
