The best prediction markets promos in 2026 include those from Polymarket, FanDuel Predicts, Kalshi, Novig and ProphetX.
Polymarket Prediction Markets Bonus
The newest Polymarket promo code SIBONUS unlocks a $20 trading bonus. New users can claim the Polymarket offer by depositing $10 or more to trade on the world’s largest prediction market and CFTC-regulated platform.
Kalshi Prediction Markets Bonus
The welcome bonus from Kalshi allows new users to get up to $500 just by trading $25 using promo code ROTOWIRE during sign-up. The up to $500 bonus stands out compared to typical offers, and given that Kalshi’s markets are highly liquid and many contracts resolve intraday, hitting $25 in trades is far more accessible than it sounds.

The Regulatory Battle and $1 Billion in Lost Tax Revenue
The American Gaming Association (AGA) has said this week that it estimates that U.S. states have missed out on up to $1 billion in gaming tax revenue due to the rise of event contracts offered by prediction market platforms.
“It’s about states and tribes that are losing literally a billion dollars today in state and tribal revenue that would otherwise go to fund important community projects,” said AGA President and CEO Bill Miller.
Prediction market platforms are offering illegal sports betting nationwide outside the state and tribal regulatory frameworks that protect consumers. They override voter decisions, bypass key consumer protections, ignore state and tribal laws, and avoid licensing and taxes.
In 2025: nearly 1 in 5 (15%) digital sports betting ads did not include responsible gaming messages. In early 2026: nearly half (43%) of digital sports betting ads did not include responsible gaming messages.
According to the survey, 81% of gaming executives viewed prediction markets as a “very significant threat” to the regulated gaming industry.
Court Rulings and CFTC Oversight
In 2024, Kalshi achieved a historic milestone by becoming the first fully regulated platform in over a century to offer legal election trading in the United States. This development followed a federal appeals court ruling that upheld Kalshi’s right to list contracts on political outcomes, including congressional control and presidential elections.
The court determined that the Commodity Futures Trading Commission (CFTC) had not provided sufficient evidence that such contracts would harm public interest or the agency. Consequently, Kalshi’s election markets operate in strict compliance with U.S. laws and regulatory standards.
