- Kalshi: trade $25 and get a $25 trading credit with code MIAPREDICTS
- Polymarket US: $50 trading bonus (Deposit $10, Get $50 Trading Bonus) + skip the waitlist access
The Short Answer
For most Florida traders: Use both. But if you're starting with one, choose Kalshi — it's more established, offers the full range of markets (including politics and hurricanes), and has the deepest liquidity for Florida-relevant events. Once Polymarket expands its US app beyond sports, the balance may shift.
How We're Comparing These Platforms
- 1.Sports (limited Hard Rock Bet competition = huge demand)
- 2.Florida politics (governor race, Senate, congressional)
- 3.Hurricane markets (uniquely relevant)
- 4.Ease of use for new traders
- 5.Fees and bonuses
Platform Backgrounds
Kalshi
Founded in 2018, CFTC-approved as a Designated Contract Market in 2021. Raised $1 billion in December 2025 at an $11 billion valuation, then was reportedly raising another $1 billion at a $22 billion valuation in March 2026. Has partnerships with CNN, CNBC, the NHL, Robinhood, and Coinbase. Over $5 billion in monthly notional trading volume. Has been operating in Florida since day one.
Polymarket
The largest prediction market in the world by overall volume ($44B+ in 2025). Was forced out of the US in 2022 after a $1.4M CFTC fine, relaunched via acquiring QCX (a CFTC-registered exchange) in November 2025. Currently in limited US mobile beta — sports only as of May 2026. The $2 billion Intercontinental Exchange (ICE) investment in 2025 gives it extraordinary institutional backing. Politics, economics, and other categories are expected on the US app later in 2026.

Liquidity
Kalshi: Over $5 billion in monthly notional volume. Deepest domestic liquidity. Tight spreads on major markets.
Polymarket: Largest prediction market in the world globally, with deep liquidity on its global platform. US app is newer and liquidity is still building.
Advantage: Kalshi for domestic markets. Polymarket globally.
User Experience
Kalshi: Clean trading interface. Shows order book, price history, and market depth. Feels like a financial platform. Some newcomers find it slightly technical.

Security and Regulation
Kalshi: CFTC-regulated DCM. One of the strictest regulatory classifications available for financial exchanges in the US. Customer funds held separately.
Polymarket: Also CFTC-regulated via its QCX acquisition. The Intercontinental Exchange investment adds institutional credibility. Its global (non-US) platform has faced criticism over outcome dispute resolution.
Advantage: Kalshi on track record. Polymarket's US regulatory standing is newer but backed by serious institutional infrastructure.
