Is Gemini legit? Our Gemini Predictions review

Is Gemini Predictions legit?

Yes. Gemini Predictions is a federally regulated exchange, owned by a Nasdaq-listed company. The Commodity Futures Trading Commission designated Gemini Titan, LLC as a contract market on December 10, 2025.

Gemini had first applied in 2020. Predictions went live five days after approval, in all 50 states. At first, trades cleared through QC Clearing, which does business as Polymarket Clearing. Since August 2026, Gemini's own clearinghouse, Gemini Olympus, clears them. The CFTC registered Olympus on April 29, 2026.

That settles “legit.” It covers less than most people assume. Regulation tells you who supervises the exchange. It does not settle state law. New York calls Gemini's markets illegal gambling, and Connecticut says the same of Gemini's sports contracts. See the lawsuits.

Is Gemini Predictions safe? How your money is held

Three Gemini companies touch your money, so it helps to know which does what. Most US accounts sit with Gemini Moonbase, LLC, a Florida-based licensed money transmitter. Customers in New York and Idaho stay with Gemini Trust Company, a New York trust company.

Idle dollars in that account may be held at partner banks, including Cross River Bank and Customers Bank. Gemini says they may qualify for FDIC pass-through insurance, subject to limits.

Trades happen on Gemini Titan, the exchange. Cash backing an open position sits at Gemini Olympus, the clearinghouse. Olympus told the CFTC it will treat that money as member property and keep it apart from its own.

Every trade is fully collateralized, so there is no margin and no default fund. Olympus may invest that collateral in US government debt and keep any profit it does not pay members. FDIC insurance covers bank deposits, not trading positions. SIPC covers securities, and event contracts are not securities.

Getting in takes ID. Gemini asks for a government photo ID, a biometric selfie and your Social Security number. Two-factor login is mandatory and cannot be switched off. Passkeys, authenticator apps and hardware security keys all work.

Is Gemini Predictions gambling?

Legally, Gemini says no. Its contracts trade on a federally regulated exchange, overseen by the CFTC rather than state gaming boards. In your wallet, the line is thin. You risk money on an outcome, and if you are wrong you lose all of it.

The real difference is who takes the other side. A sportsbook sets the odds and takes your wager itself. On Gemini, prices come from an order book, and another account takes the trade. Some are professional market makers, who can earn reduced fees and other benefits from Gemini Titan.

States see it differently. New York's attorney general calls Gemini Predictions an unlicensed gambling business. Connecticut says the same of sports contracts sold to its residents. Both say these platforms let 18- to 20-year-olds trade, where licensed sportsbooks require 21.

Federal appeals courts are split on the same question in Kalshi's cases. Every case is on our prediction market legal tracker.

Gemini Predictions lawsuits and complaints

Search for Gemini and you will find two kinds of trouble. One is the prediction market itself, which two states call illegal gambling. The other is the parent company's history, from the Earn collapse to a CFTC penalty. Here is each, with its status.

• Feb 28, 2024
  Gemini Earn and New York's banking regulator Earn lent customers' crypto to Genesis, which defaulted on about $1 billion in November 2022. New York's financial regulator fined Gemini $37 million. Gemini committed to return at least $1.1 billion to Earn customers. The SEC's Earn case against Gemini ended in January 2026, after customers recovered their crypto. Source
• Jan 6, 2025
  A CFTC penalty, later disowned A federal court ordered Gemini Trust to pay $5 million for misleading the CFTC about a 2017 bitcoin futures product. In May 2026, the CFTC and Gemini jointly asked the court to vacate that order. The CFTC now says the case should not have been filed. We found no ruling on that request yet. Source
• Mar 18, 2026
  A shareholder class action Investors sued the parent company, Gemini Space Station, in federal court in Manhattan. They say its September 2025 IPO documents misled them. The case concerns the stock, not customer accounts. Source
• Apr 21, 2026
  New York's lawsuit New York's attorney general sued Gemini Titan, calling Predictions unlicensed gambling. The state says it lets 18- to 20-year-olds trade and lists games involving New York college teams. It seeks restitution and penalties of three times Gemini's gains. Gemini moved the case to federal court, and New York wants it sent back. Source
• Sep 10, 2026
  Connecticut's cease-and-desist Connecticut ordered Gemini and eight other platforms to stop offering sports contracts to its residents. The order also tells them to let Connecticut residents withdraw their funds. Source

None of these challenges Gemini Titan's CFTC registration. We found no customer class action over Gemini Predictions in federal court records.

How Gemini Predictions works

Every market is a yes-or-no question about a real event. Contracts trade between 1¢ and 99¢, and a winning one pays $1. A losing contract pays nothing, so the price doubles as the market's probability.

You trade from your USD balance, around the clock, and can sell any time before the market closes. Each market names a third-party data source for its result. If that result is late or disputed, Gemini holds off. It decides, at its sole discretion, when the answer is reliable.

Combos join 2 to 6 contracts, and every leg must go your way to pay. There is no margin: you pay the full cost up front.

Gemini Predictions fees, with the arithmetic

0.07 × contracts × price × (1 − price) for takers; 0.0175 for makers, waived on qualifying trades through December 31, 2026. On $100 at 50¢, which buys 200 contracts, that comes to $3.50.

Notice the shape. The fee peaks at 50¢, where the outcome is least certain, and shrinks toward either end. Gemini rounds it up to the next cent. There are no settlement or membership fees.

Two programs cut the cost. Makers pay nothing on qualifying trades from September 2 through December 31, 2026. Takers with $500,000 or more in 30-day volume can earn daily USD rewards.

Moving money has its own costs. ACH and wire deposits are free, while PayPal deposits cost 2.5%. ACH withdrawals are free, and wire withdrawals cost $25.

Does Gemini Predictions pay out? Withdrawal times and holds

Yes. When a market resolves, each winning contract pays $1, added to your balance automatically. Every payout shows in your transaction history.

Getting cash out is narrower than getting it in. Withdrawals go only to a linked bank account in your name, by ACH or wire. Cards and PayPal cannot receive withdrawals. ACH withdrawals are capped at $100,000 a day.

The holds trip people up. You can trade an ACH deposit at once, at Gemini's discretion. It becomes withdrawable only after 4 to 5 business days. A password reset also freezes withdrawals for 72 hours, and an email change for 24.

What you can trade on Gemini Predictions

Gemini lists all six categories we track: sports, politics, economics, crypto, culture and weather. It adds commodities, tech and business. Some crypto contracts run as short as five minutes.

Prices are public: Gemini's API serves live market data without a key. We do not yet carry its quotes in our live prediction market odds.

Gemini said in February 2026 that more than 10,000 users had traded over $24 million since launch.

Where Gemini Predictions is available

Gemini says Predictions is available in all 50 states, to US residents only. It publishes no list of blocked states. That default is under attack in two places.

In New York, the attorney general wants a court order to stop it; no judge has ruled. In Connecticut, a September 2026 order tells Gemini to stop offering sports contracts. We found no statement from Gemini on whether it has complied.

Gemini runs its own exchange, so rulings against Kalshi do not name it. They do show where states are winning. Check your state's page before you trade.

The Gemini app and support

On the App Store, Gemini Predictions rates 4.8 from 109,786 ratings. On Google Play it rates 4.0 from 55.3K. Both were read on September 25, 2026.

Those scores cover the whole Gemini app, not just predictions. The Gemini Markets app also covers crypto trading and the Gemini credit card. Predictions is one section of it, on iOS, Android and the web.

Support runs through an online request form and email, staffed 24/7. Gemini says it never calls or texts customers unless you arrange it by email. Treat any other call as a scam. Developers also get a free API and a demo sandbox.

Gemini Predictions pros and cons

Gemini Predictions vs the alternatives

Gemini Predictions ranks second of 15 apps in our ranking of prediction market apps, at 4.7 out of 5. It suits people who already keep crypto or cash at Gemini.

Kalshi is the closest match. It also runs its own exchange and clearinghouse, charges the same base fee rates and takes debit cards. Polymarket US runs its own regulated exchange too, funded by card, bank or wire.

Our verdict: is Gemini Predictions worth it?

Gemini Predictions is legit. It is regulated at the exchange and the clearinghouse, both run by Gemini. Its fee formula is published, and makers pay nothing on qualifying trades until December 31, 2026.

The trade-offs are specific. Cards cannot fund it, and cash leaves only by bank transfer. New York is suing, and Connecticut has ordered its sports contracts stopped. As on any market here, you can lose everything you put in.

If you already hold a Gemini account, it is a short step from your balance. Check whether it is legal in your state first.
