Kalshi — US-Regulated Alternative
Kalshi holds the distinction of being the sole prediction market platform with CFTC authorization within the United States. American residents, who cannot participate on Polymarket, have access to this venue and it has experienced considerable expansion. Trade-offs include reduced market selection relative to Polymarket, and regulatory constraints that restrict certain forecast categories from being offered.
Manifold Markets — Social Prediction
Manifold operates using virtual currency ("mana") in place of actual funds. This platform serves as an excellent venue for honing forecasting abilities and engaging in group-based prediction exercises — yet it does not appeal to those seeking monetary returns. The ecosystem encompasses more than 10.000 user-generated forecast categories.
Metaculus — Forecasting Platform
Metaculus functions as an aggregator of forecast estimates from its community of professional forecasters. While no monetary stakes are involved, it excels in establishing forecast performance records and analyzing global political scenarios. The platform enjoys recognition in scholarly literature examining forecast quality.
Betfair — The Legacy Exchange
Betfair represents the original peer-to-peer wagering exchange, processing enormous sums across athletic competitions and electoral contests on an annual basis. Strengths include conventional payment methods, regulatory approval from the FCA, and substantial liquidity in sports-related markets. Limitations encompass commissions ranging from 2 to 5 % on net returns, absence of blockchain-based asset markets, and narrower political market offerings in comparison to Polymarket.

For participants outside the United States and those seeking maximum market depth and selection: Polymarket through PolyGram emerges as the superior option.
