Kalshi vs Polymarket (2026)
Both are now legal CFTC-regulated US prediction markets. The real question is device + market mix — Kalshi is universal, Polymarket is iPhone-only with a bigger bonus and the deepest political market in the world.
Both are legal in the US in 2026. Pick Kalshi (code MIAPREDICTS, $25 bonus) if you're on Android or desktop, or want US sports / weather / macro depth. Pick Polymarket (code MIAPREDICTS, $50 trading bonus) if you have an iPhone and want the deepest political and cultural markets. Most active US traders run both.
Florida-specific: both are legal in all 67 counties for residents 18+. Kalshi lists Miami Heat, Dolphins, Marlins, Panthers, Inter Miami, and Atlantic-basin hurricane contracts; Polymarket dominates FL gubernatorial and US election markets.

- You want a real $25 trading credit at signup

The bottom line for a Florida trader
Florida traders now have two legitimate CFTC-regulated options. Kalshi is the everyday workhorse — works on every device, broadest US-domestic catalog, easiest tax flow. Polymarket is the politics specialist with a bigger welcome bonus and the deepest liquidity on US elections and global political markets, but only if you're on an iPhone.
The smart move for active traders is running both. Use Kalshi for sports, weather, and macro; use Polymarket for politics and culture; arbitrage when both list the same event. If you're forced to pick one, pick by device first (Android or desktop → Kalshi) and market mix second.
