1 Kalshi — Best Overall Prediction Market App

Kalshi App Overview

iOS & Android CFTC-regulated USD deposits $0.02/contract fee No minimum deposit

Kalshi is the top-ranked prediction market app for 2026 and the gold standard for regulated event contract trading in the United States. As the first CFTC-regulated prediction market exchange, Kalshi lets you trade on hundreds of real-world events — from elections and economic data to weather and pop culture — using real US dollars.

The Kalshi app is available as a native download on both iOS (App Store) and Android (Google Play). The mobile experience mirrors the desktop platform closely, with a clean interface for browsing markets, placing orders, and managing your portfolio on the go.

Key Features

Fee Structure

Kalshi charges a flat fee of $0.02 (2 cents) per contract on every trade, whether you are buying or selling. There are no deposit fees (ACH), no withdrawal fees (ACH), no settlement fees, and no account maintenance fees. For a detailed breakdown, see our Kalshi fees guide.

Example trade on Kalshi:

Buy 100 "Yes" contracts on "Will the Fed cut rates in June?" at $0.45 each
Contract cost: 100 × $0.45 = $45.00
Trading fee: 100 × $0.02 = $2.00
Total cost: $47.00

If Yes wins: 100 × $1.00 = $100.00 payout → +$53.00 profit
If No wins: $0.00 payout → -$47.00 loss

Pros

  • CFTC-regulated (highest legal protection)
  • Native iOS and Android apps
  • USD deposits via bank transfer (no crypto)
  • 1099 tax forms issued automatically
  • Hundreds of diverse markets
  • Simple, transparent 2-cent fee
  • No minimum deposit
  • Clean, intuitive mobile UI

Cons

  • 2-cent fee is higher than Polymarket
  • US-only (not available internationally)
  • ACH deposits take 1-3 business days
  • Fewer markets than Polymarket
  • Spreads can be wide on less popular markets

2 Polymarket (PWA) — Lowest Fees & Deepest Liquidity

Polymarket PWA Overview

PWA (iOS & Android) Offshore USDC deposits ~0% maker fees Not available in US

Polymarket is the largest prediction market by trading volume and offers the deepest liquidity on major events. While it does not have a native app in the App Store or Google Play, Polymarket works as a Progressive Web App (PWA) that you can install on your phone's home screen for an app-like experience.

Polymarket uses USDC (a stablecoin pegged to the US dollar) on the Polygon blockchain for trading. This means near-zero trading fees but requires users to own or purchase cryptocurrency to trade. For a full walkthrough, see our how to bet on Polymarket guide.

Key Features

Fee Structure

Polymarket offers the lowest trading fees of any real-money prediction market. Maker orders (limit orders) are essentially free, and taker orders cost approximately 0.01%. There are no deposit or withdrawal fees beyond minimal Polygon gas fees (typically under $0.01). See our Polymarket vs Kalshi comparison for a detailed fee analysis.

Pros

  • Near-zero trading fees
  • Largest market selection
  • Deepest liquidity on major events
  • PWA works on any device
  • No minimum trade size
  • Fast settlement
  • Active community and comments

Cons

  • Requires cryptocurrency (USDC) to trade
  • Not available to US residents
  • No native app store listing
  • No 1099 tax forms (self-report)
  • Not CFTC-regulated
  • PWA lacks push notifications on iOS

Try Polymarket

Lowest fees and deepest liquidity. Thousands of markets on every topic.

3 Robinhood — Best for Stock Traders

Robinhood Event Contracts Overview

iOS & Android CFTC-regulated USD deposits $0 commission US only

Robinhood added event contracts to its popular stock trading app, making it the easiest way for existing Robinhood users to start trading prediction markets. With zero explicit trading commissions and a familiar, polished mobile interface, Robinhood lowers the barrier to entry for prediction market newcomers.

However, Robinhood's event contract selection is significantly more limited than Kalshi's or Polymarket's, and the platform earns revenue through wider bid-ask spreads and payment for order flow (PFOF). For a deep dive, read our Kalshi vs Robinhood comparison.

Key Features

Fee Structure

Robinhood charges $0 in explicit commissions on event contract trades. However, the platform makes money through wider bid-ask spreads and PFOF, so your all-in trading cost may be comparable to Kalshi's 2-cent fee. Deposits and withdrawals are free.

Pros

  • Zero explicit commission
  • Best-in-class mobile app design
  • Instant deposits for Gold members
  • Integrated with stocks and crypto
  • CFTC-regulated
  • 1099 tax reporting
  • Huge existing user base

Cons

  • Very limited market selection
  • Wider bid-ask spreads (hidden cost)
  • PFOF may result in worse execution
  • No order book transparency
  • Fewer market categories
  • Event contracts are an add-on, not the core product

Should You Use Robinhood or Kalshi?

If you already have a Robinhood account and mainly want to trade high-profile events (elections, major economic indicators), Robinhood is convenient. If you want access to a wider variety of markets, deeper order books, and a platform built specifically for event contracts, Kalshi is the better choice. Read our full Kalshi vs Robinhood comparison.

4 Manifold Markets — Best Free Prediction Market App

Manifold Markets Overview

iOS, Android & Web Play money Free to use User-created markets Global

Manifold Markets is a free, play-money prediction market platform where anyone can create markets on any topic. It is the best way to practice forecasting without risking real money. With native apps for both iOS and Android, Manifold offers a polished mobile experience and one of the most active prediction market communities online.

While Manifold uses play money (called "mana"), the platform serves as an excellent training ground for developing your forecasting skills before moving to real-money platforms like Kalshi or Polymarket.

Key Features

Fee Structure

Manifold is completely free to use. There are no trading fees, no deposit fees, and no withdrawal fees because all trading is done with play money. Users receive free mana daily and can earn more by making accurate predictions.

Pros

  • 100% free — no real money risk
  • Native iOS and Android apps
  • Anyone can create markets
  • Great for learning and practice
  • Active community
  • Available worldwide
  • Multiple market types

Cons

  • Play money only — no real profits
  • Market resolution depends on creators
  • Less serious liquidity than real-money platforms
  • Some markets are poorly defined
  • No regulatory oversight

5 Metaculus — Best for Forecasting & Calibration

Metaculus Overview

Web (mobile-responsive) Reputation-based Free to use Expert community Global

Metaculus is a forecasting platform that focuses on calibration and accuracy rather than trading. Users submit probability estimates for questions about science, technology, politics, and more, then track how well-calibrated their predictions are over time. It is not a traditional prediction market app with buying and selling, but rather a forecasting tournament platform that attracts serious forecasters and researchers.

Metaculus does not have a native app but offers a mobile-responsive website that works well on both iOS and Android browsers.

Key Features

Fee Structure

Metaculus is completely free. There is no real money or play money involved. Users forecast by submitting probability distributions, and their accuracy is tracked over time through a scoring system.

Pros

  • Free to use
  • High-quality, well-defined questions
  • Excellent calibration tracking tools
  • Respected by researchers and institutions
  • Available worldwide
  • Great for building forecasting skill
  • Forecasting tournaments with prizes

Cons

  • No real money trading
  • No native mobile app
  • Not a traditional prediction market
  • Steeper learning curve
  • Smaller community than Polymarket or Manifold

6 PredictIt — Best for Politics-Only Markets

PredictIt Overview

Web (mobile-responsive) CFTC no-action letter USD deposits 5% profit fee + 5% withdrawal fee US available

PredictIt is one of the longest-running prediction market platforms in the United States, operating under a CFTC no-action letter since 2014. The platform focuses almost exclusively on political markets — elections, legislation, and government policy. PredictIt does not have a native app but offers a mobile-responsive website.

PredictIt has faced regulatory uncertainty in recent years, with the CFTC withdrawing its no-action letter. The platform's future is uncertain, but it continues to operate and maintains an active community of political forecasters.

Key Features

Fee Structure

PredictIt charges two fees that add up to a significant cost:

These combined fees make PredictIt significantly more expensive than Kalshi or Polymarket. For example, a $10 profit would cost you $0.50 in profit fees, and withdrawing $100 costs $5.00.

Pros

  • Real money trading available in the US
  • Deep political market expertise
  • Long operating history
  • Active community of political junkies
  • Low minimum trades ($1)

Cons

  • High fees (5% profit + 5% withdrawal)
  • No native app
  • Limited to political markets
  • $850 position limit per contract
  • Uncertain regulatory future
  • Outdated interface

7 Polymarket.com (Desktop) — Best Browser-Based Experience

Polymarket Desktop Overview

Web browser Offshore USDC deposits ~0% maker fees Not available in US

While we covered Polymarket's PWA above, the desktop browser experience at Polymarket.com deserves its own mention. The full website offers features that the mobile PWA cannot match, including advanced charting, deeper order book views, and multi-market portfolio management.

If you primarily trade from a computer, Polymarket.com provides the most comprehensive prediction market trading interface available. It is essentially the "Bloomberg Terminal" of prediction markets.

Key Desktop-Only Features

Pros

  • Best desktop trading interface
  • Advanced charting and analytics
  • Full order book visibility
  • API for automated trading
  • Near-zero fees
  • Deepest liquidity

Cons

  • Desktop only (PWA for mobile)
  • Requires cryptocurrency
  • Not available in the US
  • No regulatory protection
  • Self-report taxes

Our Recommendation

For most US-based traders, we recommend starting with Kalshi as your primary prediction market app. It offers the best combination of regulation, market selection, mobile experience, and ease of use.

What Are Event Contracts? How Prediction Market Apps Work

If you are new to prediction markets, here is a quick primer on how these apps work under the hood.

Event contracts (also called binary options or prediction market contracts) are financial instruments that pay out based on whether a specific real-world event happens or not. Each contract is a simple yes-or-no question:

How Contracts Work

The basics of event contracts:

1. Each contract trades between $0.01 and $0.99
2. The price represents the market's implied probability (e.g., $0.65 = 65% chance)
3. If the event happens, "Yes" contracts pay out $1.00. If not, they pay $0.00
4. You profit by buying low and having the event resolve in your favor
5. You can also sell your position before the event resolves to lock in profit or cut losses

The beauty of prediction market apps is that contract prices naturally reflect the crowd's collective wisdom about the probability of events. If a contract for "Will Candidate X win?" trades at $0.72, the market believes there is roughly a 72% chance that Candidate X wins.

This makes prediction market apps useful not just for trading, but also for getting accurate probability estimates about future events. Research has consistently shown that prediction markets outperform polls, pundits, and expert panels at forecasting outcomes.

Frequently Asked Questions About Prediction Market Apps

What is the best prediction market app?

Kalshi is the best overall prediction market app in 2026. It is CFTC-regulated, offers native iOS and Android apps, accepts USD deposits via bank transfer, issues 1099 tax forms, and has hundreds of markets across politics, economics, weather, and culture. For the lowest fees, Polymarket is the top choice (if you are outside the US and comfortable with crypto).

Is there a prediction market app for iPhone (iOS)?

Yes. Kalshi has a native iOS app available on the App Store for real-money event contract trading. Robinhood also offers event contracts within its iOS app. Polymarket can be installed as a PWA from Safari. Manifold Markets has a native iOS app for play-money trading. All of these work well on iPhone.

Is there a prediction market app for Android?

Yes. Kalshi and Manifold Markets both have native Android apps on the Google Play Store. Robinhood's Android app includes event contracts. Polymarket works as a PWA on Android Chrome. All major prediction market platforms are accessible on Android devices.

Are prediction market apps legal in the US?

Yes, certain prediction market apps are legal in the US. Kalshi is fully regulated by the CFTC as a Designated Contract Market (DCM). Robinhood offers CFTC-regulated event contracts. PredictIt operates under a CFTC no-action letter. Polymarket is not available to US residents for real-money trading because it operates offshore. Manifold and Metaculus are legal everywhere since they use play money or reputation points.

Which prediction market app has the lowest fees?

Polymarket has the lowest explicit trading fees (~0% for maker orders, ~0.01% for taker orders). Robinhood charges zero commission but earns through wider spreads. Kalshi charges a flat 2 cents per contract. PredictIt is the most expensive with 5% on profits and 5% on withdrawals. Manifold and Metaculus are free but do not use real money.

How much money do I need to start using prediction market apps?

Most prediction market apps have very low minimums. Kalshi has no minimum deposit, and contracts cost as little as $0.01 each. Robinhood has no minimum for event contracts. Polymarket requires USDC but has no minimum trade size. Manifold and Metaculus are completely free. You can realistically start with as little as $5-10 on real-money platforms.

What is the difference between prediction market apps and sports betting apps?

Prediction market apps let you trade on non-sports events (elections, economics, weather, culture) using event contracts regulated by the CFTC as financial instruments. Sports betting apps focus on athletic events with traditional bet formats and are regulated by state gaming commissions. Key differences: prediction markets let you sell your position before resolution, use an order book for price discovery, and are treated as financial products rather than gambling.

Can I use multiple prediction market apps at the same time?

Yes, and many experienced traders do. Using multiple apps lets you compare prices across platforms and find the best odds for each trade. For example, you might use Kalshi for regulated US markets, Polymarket for the deepest liquidity on major events, and Manifold for practice. Use PredScope to compare prices across platforms in real time.

Do prediction market apps report to the IRS?

Kalshi and Robinhood both issue 1099 tax forms for US traders, making tax reporting straightforward. Polymarket does not issue tax forms since it operates offshore; you must self-report crypto gains. PredictIt issues 1099s. Regardless of which app you use, you are legally required to report prediction market profits on your US tax return.
