Gemini Predictions App Review October 2026 The Complete Guide for US Users

Gemini’s prediction market is federally regulated. Its affiliate, Gemini Titan, LLC, was designated by the CTFC as a Designated Contract Market in December 2025. If you're wondering how regulation applies to event contracts across the country, you can read our breakdown on whether prediction markets are legal in the US.

But regulatory credentials alone don’t make a prediction market platform worth trading on. That’s why in this Gemini Predictions review, we’ll show you how Gemini works, which event contracts are available, what trading and transaction fees apply, and how easy it is to manage positions. We’ll also assess whether Gemini has what it takes to challenge established brands in the space like Polymarket and Kalshi.

Gemini Predictions Bonuses and Incentives

Gemini's welcome offer is a 50% trade match on pro football contracts, worth up to $100 in Predict Cash for new users. It sits alongside a referral program and several incentives for market makers. If you want to see how this deal compares to other top offers, explore our guide to the best US prediction market bonuses.

Welcome Offer: 50% Trade Match up to $100

New Gemini users get a 50% match on their pro football trades, paid as Predict Cash and capped at $100. No promo code is needed, and the match applies automatically to eligible pro football contracts priced between 20¢ and 80¢. Trade $50 to get $25, $100 to get $50, or $200 to get the full $100.

Predict Cash can't be withdrawn or transferred, so you use it on future trades. The offer runs through February 14, 2027, and trades on other sports or markets don't count toward it.

Referral Program: $50 in Crypto for Both Users

You and your friend can get $50 in cryptocurrency of your choice via Gemini's referral program. All the other person must do to qualify is register at Gemini with your invite and trade $100 within their first 30 days on the platform.

Incentives for Market Makers

Gemini has several incentives for market makers:

• Maker fee-free trading promo: This is a time-limited promotion running until the end of the year, waiving maker fees on eligible executed trades.

• Maker rebate program: The program calculates rebates as a percentage of the taker fees generated by eligible executions. Rates vary by market, and qualifying orders must execute within the specified price range of $0.20 to $0.80. Rebates are paid daily in USD.

• Liquidity rewards program: Users can receive USD rewards for maintaining qualifying resting orders, even when they don't execute.

• Taker rewards program: This is a volume-based program with daily rewards and monthly bonuses. The daily reward rate scales with a user's trailing 30-day taker volume and can range between 0.05% and 1.50%, while monthly bonuses can reach up to $50,000.

Sign up to Gemini Exchange

Gemini Predictions User Experience

Gemini is a broader cryptocurrency exchange with multiple services and products, but its Predictions section is well organized and simple enough for beginners. The layout makes it easy to browse event contracts, compare prices, analyze charts, and find markets without getting lost in the exchange's wider features. Understanding how to read prediction market odds and share prices makes navigating these listings and evaluating payout probabilities even easier.

You can access Gemini’s predictions on desktop or download the iOS and Android apps.

Desktop

The site uses a horizontal top menu to categorize its prediction markets across politics, sports, crypto, tech, currently trending events like Midterms, and more.

Featured events appear in a carousel at the top of the page, so popular markets have immediate visibility. There are also sorting options that let users organize contracts by Featured, Volume, 24h Volume, Newest, and Expiry Date, making it easy to track popular US prediction market events or narrow the selection based on personal preferences. The search bar also adds a few filters like Live, Trending, and Ending Soon and keeps track of your recently viewed events.

A prominent Create Combo button next to the search button introduces Gemini's new combo builder that was added in September. This means you can now combine multiple event outcomes into a single position.

When opening an event, you can see "Contract Intelligence" and "About" sections for additional information about the underlying event. It’s a neat feature, as these details help you understand the contract better instead of relying solely on the headline and Yes/No prices.

Gemini App

The Gemini Predictions app is available at both the App Store and Google Play. The iOS app has a 4.8-star rating from around 110,000 ratings, while the Android app holds 4.0 stars from approximately 55,000 reviews.

The app runs fluently and makes the prediction market section easy to access. A bottom navigation bar includes a dedicated Predict button, so you can jump straight into event markets without navigating through multiple menus. The interface feels responsive, and browsing and opening contracts is quick and straightforward.

Gemini Predictions Markets Available

Gemini Predictions covers sports, politics, crypto, commodities, economics, technology, business, weather, and culture, with depth varying widely by category.

Sports Markets

Sports prediction markets at Gemini include football, baseball, basketball, hockey, soccer, golf, motorsports, MMA, and chess. The platform offers several market types, including game winners, spreads, totals, futures, and player props, though the latter are more prominent in football and rarely appear in other sports.

The league coverage is a bit limited. For example, basketball markets exclusively focus on the NBA and WNBA, while Polymarket offers options across a much wider range with over a dozen international leagues and competitions. If you want to learn more about how trading these contracts differs from traditional sportsbooks, check out our detailed guide on prediction markets and how to use them to bet on sports.

Politics and Elections

Political markets cover US presidential andcongressional politics, local elections, court-related developments, and international events. US politics remains a major focus, with markets on which party will control the House or Senate and who will win individual elections. International coverage includes events such as Brazil's presidential election and France's 2027 presidential race.

Also, Gemini may give extra visibility to currently trending political events like Midterms with a separate shortcut in the main menu.

Crypto Markets

Gemini offers price-based contracts on several cryptocurrencies, including Bitcoin, Ether, Solana, Hyperliquid, XRP, and Zcash. Both short- and long-term price targets are included, with five-minute, 15-minute, hourly, daily, weekly, and monthly contracts, depending on the asset.

However, there is a lack of broader crypto-related questions that I’ve seen on the best prediction markets, like when Bitcoin will cross $100k again or whether a Mag7 company will launch a stablecoin by the end of the year.

Commodities and Economics

The commodities section covers six options: WTI crude oil, Brent crude oil, natural gas, gold, silver, and copper, with contracts focusing on whether prices reach specified levels by a specific time.

Economic markets add Federal Reserve decisions, inflation, employment, and other macroeconomic indicators.

Technology, Business, Weather, and Culture

Gemini also branches into topics beyond traditional sports and financial markets. Technology markets cover developments in the tech sector like AI and space, while business markets include company-related questions and potential IPO timelines. Weather markets focus on daily temperature predictions across the country, and culture covers entertainment outcomes for film releases, video games, and awards.

These categories add welcome variety, but they don’t show much depth. Some events attract several related contracts, while others have only a handful of outcomes or no active markets at a particular time. The interface is broad enough to appeal to users with varied interests, but once you check out each of these categories, you can see that doesn't necessarily translate into a deep inventory within each one.

Market Volume and Liquidity

As expected, liquidity at Gemini is strongest around high-profile sports events and major political stories. However, the activity drops off drastically for less widely followed markets. For example, I found only $12 total volume on a daily copper price contract just 13 hours before closing.

Low trading volume on some of these markets can mean fewer available counterparties, wider spreads, and more difficulty executing a larger order at the displayed price. In turn, traders prioritizing extensive coverage and deeper liquidity across niche subjects will find more to explore on larger platforms. Understanding basic trading strategies for prediction markets and event contracts can also help you manage risk and execute orders more effectively in low-volume markets.

Gemini Predictions Banking & Fees

Gemini uses separate maker and taker fee formulas to calculate the cost of making predictions. Meanwhile, US users can deposit and cash out funds using ACH, wire transfers, and PayPal.

Gemini Predictions Trading Fees

The maker rate at Gemini is 1.75%, and the taker rate stands at 7% of the contract's price-weighted fee base. The fee is then calculated using the following formula:

• Maker fee: 0.0175 × number of contracts × price × (1 − price)

• Taker fee: 0.07 × number of contracts × price × (1 − price)

This means that the fees are highest when a contract is priced at $0.50, while they decrease toward either price extreme. Here are a few examples:

Fees are always rounded up to the next cent. Gemini doesn't charge a fee for canceling an unfilled maker order, and there are also no settlement or membership fees. However, bear in mind that contracts listed before March 18, 2026 are subject to the previous fee schedule.

Another thing to consider is that Gemini is currently running a maker-fee-free promotion through December 31, 2026. Qualifying executed maker orders across eligible event contracts incur no maker fee during this period, but taker fees still apply under the applicable schedule.

Gemini Predictions Deposits & Withdrawals

US users can generally fund their Gemini accounts using ACH bank transfers, domestic wire transfers, or PayPal. Debit cards, Apple Pay, and Google Pay are available for eligible crypto purchases on the platform, but they aren’t accepted as direct deposit methods for funding your prediction trading account.

ACH and PayPal deposits usually go through instantly. ACH withdrawals can take up to five business days, while wire transfers go through in one to three days both ways.

Gemini Predictions Customer Support

Gemini Predictions customer support is open 24/7 and available through live chat, email, and a resourceful Help Center.

• Live chat: Support starts with an automated bot that directs users to relevant information from the Help Center. If this doesn't resolve the issue, users can request further assistance from a human rep.

• Email: You can contact support through direct email at cryptopediasupport@gemini.com or by filling out a contact form on the website.

• Help Center: Gemini's searchable Help Center contains detailed articles covering account management, identity verification, deposits and withdrawals, security, and trading.

Gemini Predictions Quick Overview

Gemini Predictions Final Verdict

Gemini Predictions is a credible option for US traders. The platform has a clean interface, functional mobile apps, a transparent fee structure, and a good mix of markets overall.

However, it still has ground to make up against Polymarket and Kalshi. Its sports inventory is comparatively very thin, with niche markets that can have limited trading volume. Its welcome offer, a 50% trade match worth up to $100 on pro football contracts, gives newcomers a reason to start, though it only rewards football trading. The maker rewards program is certainly a positive for active liquidity providers.

I would use Gemini if I already use its exchange or value keeping my crypto activity and event-contract positions under one account. If extensive market coverage and liquidity across less popular events are your priorities, I'd rather switch to Polymarket, Kalshi, or some other top platform.

Responsible Risk Management

WSN encourages informed decisions and responsible risk management. Prediction markets involve financial risk, and traders can lose their entire investment on an unsuccessful position. Contract prices fluctuate as market expectations change, while low liquidity can make it harder to exit a position at a favorable price. Review each contract's settlement rules, fees, and potential loss before trading and use only the money you can afford to lose.

Gemini doesn’t have loss-limit or deposit-limit controls, so users are left on their own to manage their spending. 

How We Rate Prediction Markets

Our standard review methodology uses a $1,000 testing budget over two weeks. For this review, I deposited all $1,000, made around $750 worth of trades, and ended up with $880 in my account before initiating a withdrawal.

During the testing period, I was able to assess the platform’s bonuses and UX features, comb through various markets, study the fee structure, explore the banking options, and talk to support.

Testing also considered how easily users can find contract details and understand the conditionsrelated to settlement.

Why You Should Trust Us

WSN focuses on the details that may affect your real trading decisions. It’s not enough to say that a platform covers a wide range of markets and has a nice app. Regulatory status, contract terms, market liquidity, fees, funding methods, and the practical usability of the platform all matter, as well. Instead of spewing out promotional claims, our approach is fully hands-on, as we make observations wherever testing is possible.
