What Makes a Good Prediction Market App
Not all prediction market platforms are created equal. When evaluating apps, we focus on five criteria that directly impact your trading experience and fund safety:
Regulation and Fund Safety
The most important factor. A CFTC-regulated exchange means your funds are held in segregated accounts, trading is monitored for manipulation, and the platform must follow strict transparency rules. Unregulated platforms carry counterparty risk — if the company goes under, your funds may not be protected.
Market Coverage
The best apps offer markets across multiple categories: sports, politics, economics, weather, science, and culture. More markets means more opportunities to trade on topics you understand. Look for both breadth (number of categories) and depth (number of contracts within each category).
App Quality and UX
Mobile-first design, fast execution, real-time price updates, clean portfolio tracking, and intuitive market discovery all matter. A clunky app costs you time and can lead to missed opportunities or execution errors. App store ratings above 4.5 generally indicate a polished experience.
Fees and Pricing
Exchange fees typically range from 1 to 7 cents per contract. Lower fees mean more of your profit stays in your pocket. Also compare deposit and withdrawal fees, since some platforms charge for bank transfers or debit card funding. For context on how fees compare to traditional betting, read our comparison guide.
Liquidity and Volume
Higher trading volume means tighter spreads (smaller gap between buy and sell prices) and faster order execution. Low-liquidity markets may have wide spreads that eat into profits, or you may not be able to exit a position at a reasonable price. Check daily trading volume before committing significant capital.

Kalshi is the clear market leader among US prediction market apps. As the only exchange holding a CFTC Designated Contract Market (DCM) license, Kalshi offers the strongest regulatory protections available — the same oversight framework that governs the Chicago Mercantile Exchange and other major derivatives markets.
Market Coverage
Kalshi offers the broadest market selection of any US prediction market platform. You can trade event contracts across politics (elections, policy decisions, Supreme Court rulings), economics (Fed rate decisions, CPI data, GDP reports, unemployment figures), sports (championship winners, game outcomes, award races), weather (hurricanes, temperature records, rainfall), science and tech (FDA approvals, SpaceX launches), and culture (awards shows, viral events).
During the 2026 FIFA World Cup, Kalshi attracted over 3 million users to its sports event markets — demonstrating both the platform's ability to handle massive volume and the growing mainstream appeal of prediction market trading. For a full explanation of how these contracts work, see our prediction markets guide.
App Experience
The Kalshi mobile app (iOS and Android) carries a 4.7/5 rating based on tens of thousands of reviews. The interface is clean and intuitive: browse markets by category, tap to view price charts and order books, and execute trades in seconds. Portfolio tracking shows your open positions, P&L, and trade history in a single view.
The desktop web experience is equally polished, with advanced charting, price alerts, and the ability to place limit orders at specific prices. Power users appreciate the API access for algorithmic trading strategies.
Fees and Deposits
Kalshi charges 1 to 7 cents per contract in exchange fees, depending on trading volume and market type. There is no minimum deposit. Funding options include ACH bank transfer (free, 1-2 business days), debit card (instant, small fee), and wire transfer (same day for large amounts). Withdrawals via ACH are free and typically processed within 1-3 business days.

Trade on KalshiHow Other Platforms Compare
Beyond Kalshi, a few other prediction market platforms exist. None carry CFTC regulation, and most target different audiences or geographic regions. Here is a brief overview for context.
Polymarket
Polymarket is a crypto-based prediction market platform built on blockchain technology. It offers markets on politics, crypto events, and cultural topics. Deposits and withdrawals use USDC (a stablecoin). Polymarket is popular among crypto-native users and international traders, but it does not hold CFTC regulation and has faced regulatory scrutiny in the United States. US residents should carefully review the platform's terms and legal standing before trading.
PredictIt
PredictIt operated under a CFTC no-action letter as an academic research platform run by Victoria University of Wellington. The CFTC withdrew the no-action letter in 2023, and PredictIt wound down most of its operations. While the platform still technically exists in limited form, it is no longer accepting new markets and has severe position limits ($850 per contract). PredictIt is not a viable option for most traders in 2026.
Metaculus & Others
Several platforms focus on forecasting rather than real-money trading. Metaculus, Manifold, and Good Judgment Open let users make probability predictions and build forecasting track records, but they do not involve real-money contracts. These can be useful for developing prediction skills before committing capital on a regulated exchange like Kalshi.
Our Recommendation
For US-based traders, Kalshi is the only platform we recommend. CFTC regulation provides critical fund protections and market integrity guarantees that unregulated platforms cannot match. If you want to practice forecasting without real money, free platforms like Metaculus and Manifold are worth exploring. For real-money prediction market trading, Kalshi is the standard.
Key Features to Look For
When evaluating any prediction market app, focus on these features that directly impact your experience and profitability:
Limit Orders
The ability to set a price and wait for the market to come to you. Instead of buying Yes at the current 42 cents, you can place a limit order at 38 cents and get filled if the price drops. This is essential for patient traders seeking optimal entry points. Kalshi supports full limit order functionality on all markets.
Real-Time Price Charts
Price history charts show how market sentiment has shifted over time. A contract that has steadily climbed from 20 to 60 cents over three weeks tells a different story than one that spiked from 20 to 60 cents overnight on a single news event. Charts help you identify trends, support levels, and potential entry points.
Portfolio Analytics
Tracking your positions, unrealized P&L, win rate, and return on capital across all markets helps you refine your strategy. The best apps show at-a-glance portfolio performance and detailed per-trade analytics. Kalshi's portfolio view tracks all open and settled positions with full history.
Push Notifications & Alerts
Price alerts notify you when a contract crosses a threshold you set. Settlement notifications confirm when events resolve and funds are credited. Market launch alerts tell you when new contracts become available in categories you follow. These keep you informed without constantly checking the app.
API Access
Advanced traders build algorithmic strategies that automatically place trades based on data feeds, price movements, or model outputs. API access lets you connect your own tools to the exchange. Kalshi offers a well-documented REST API for programmatic trading. This is a power-user feature, but it is increasingly important as prediction markets mature.
