The global benchmark
Polymarket is the deepest prediction market on the planet. The 2024 US election alone saw billions of dollars in volume on Polymarket contracts, which were frequently quoted by mainstream financial media.
The US relaunch
Polymarket re-entered the US through a CFTC-regulated pathway. The US offering is iPhone-only — there is no Android app or US web checkout yet. New US signups can claim a $50 trading bonus with code MIAPREDICTS after a $10 deposit.
What to expect
Polymarket's catalog will likely lead with politics, geopolitics and culture — categories where it has historically had no equal. Sports coverage is expanding rapidly. UX-wise, the app and web client are excellent, with TradingView-style charting on every market.
Fees and pricing
Polymarket's US offering uses an order-book model with low maker/taker fees — typically a fraction of a percent per fill. Deposits via the in-app funding flow are free; withdrawals route back to your funding source in 1–3 business days.
Safety and regulation
The US Polymarket app operates under CFTC oversight. Customer funds are segregated at US banks. The international Polymarket protocol is a separate entity — your US account is governed by the US-regulated structure with its own KYC.
Polymarket vs Kalshi
Kalshi has broader device support (iOS + Android + web), a wider sports catalog and instant debit withdrawals. Polymarket has historically deeper political markets and a larger global trader base. If you have an iPhone, run both; if you're on Android in the US, start with Kalshi.
Should you wait?
If you're on iPhone in Florida, sign up today with code MIAPREDICTS, deposit $10 and claim the $50 trading bonus. If you're on Android, use Kalshi (code MIAPREDICTS, trade $25 get $25) until Polymarket ships an Android app.
