OG.com Prediction Markets Review 2026: Markets, Contracts, Fees, and Trading Experience

My opinion on OG

Before you go through the full review, the table below will give you the most important highlights that you need to know about OG.

How does OG work? Trading simply explained

OG is a marketplace where users trade contracts that are tied to the future result of a real-world event, such as a tournament. The value or price of an event contract moves up and down, depending on the confidence of marketplace participants in the outcome of the event.

OG has event contracts for different kinds of events related to politics, sports, entertainment and the economy. The platform works by defining specific events with a yes or no outcome. It also creates a space for buyers and sellers to transact, based on demand and supply. OG is a regulated prediction markets platform, and like all event contracts, trading on OG involves risk, and you can lose the amount you pay for a contract.

Contract prices range from $0.01 to $0.99. You can read this contract price as the implied market probability, so $0.80 means the market believes there is a 80% probability of that happening. When the event ends and the outcome is known, the event contract can’t be traded again. The correct contracts will settle at $1, while wrong contracts will settle at $0.

How it all works in practice

If you are new to prediction markets, I will show you an example to explain how trading on OG works. Let’s assume that you purchase 100 “yes” contracts at $0.40.

Total price of contracts = 100 x $0.40 = $40

Taker fee = 0.07 x number of contracts x P x (1 – P); P = contract price

Taker fee = 0.07 x 100 x 0.40 x (1 – 0.40) = $1.68

Outlay = Total price + taker fee = 40 + 1.68 = $41.68

If you are right about the event’s outcome, you get a net profit of $100 – $41.68 = $58.32. If you are wrong about the event’s outcome, you will lose $41.68.

If the price rises to $0.65, the new calculation will become:

Total price of contracts = 100 x $0.65 = $65

Taker fee = 0.07 x number of contracts x P x (1 – P); P = contract price

Taker fee = 0.07 x 100 x 0.65 x (1 – 0.65) = $1.5925 = ~ $1.60

You will receive a net amount of $65.00 – $1.60 = $63.40.

Contract types on OG

There are three major contract types on OG:

• Binary contracts (Yes/No): A binary contract has a yes or no outcome. It will pay $1 if the event comes to pass and $0 if it does not. For example, a binary contract for basketball is on the event “Will Boston win their next game?”
• Multi-outcome contracts: A multi-outcome contract usually has more than two outcomes. If there are three teams competing for a championship, a multi-outcome contract will be “which team will win the trophy”.
• Range-style contracts: This type of contract deals with a numerical range of outcomes, rather than a yes/no answer. An example could be the value of tomorrow’s temperature by 2:00pm in the afternoon. There could be three possible results with temperature ranges given by 20-24°C (paying $0.25), 25-29°C (paying $0.55), and 30-34°C (paying $0.20).

OG prediction markets: What you can trade

The OG prediction markets cover a wide range of activities like sports, entertainment, cryptocurrency, economics, politics and more. Let me show you each category in greater detail:

Sports

OG’s main focus is the sports predictions category. I saw football, boxing, sailing, basketball, soccer, tennis, motorsport, baseball and hockey with up to 300 competitions across these categories. The soccer section included major leagues like the top-flight leagues in Germany, Spain, England and Italy. OG also has its dedicated football hub tab.

Some of the market types available in OG sports category include total, winner, spread and player props. Live in-game trading is available for certain events. The event contracts for sports usually settle after official results. For soccer, that will be after the 90 minutes plus stoppage time. Keep in mind that overtime counts in basketball, football and hockey markets.

Cryptocurrency

There are more than 10 cryptocurrencies with prediction markets on this platform, with the likes of Bitcoin, XRP, DOGE, Solana, Ethereum, etc.

OG gives you the chance to trade one-time, 5-minute, 20-minute, 2-hour, and weekly crypto prediction markets. For example, a one-time prediction market could be based on a specific “Yes” or “No” event such as “Will Bitcoin close over $100,000 on December 31, 2026?”

Financials and commodities

OG allows you to trade major stocks, commodities and financial instruments. You get to trade major FOREX pairs like GBP/USD and EUR/USD. I also traded my fair share of stock market indices like NASDAQ 100, Russell 2000 and S&P 500. Commodities such as crude oil, gold and silver are also available. Under this category, the taker fee is a flat $0.02 per contract.

Economics

OG economics prediction market is not as extensive as its sports category. If you follow US economic activity related to inflation, US recession statistics, and Federal Reserve decisions, you can try out the OG economics market.

Politics

The politics market is where you mainly trade the outcomes of the US state governorship election, US presidential election and the selection of US house of representative members.

The prediction markets related to international politics are few. One trade contract that I found in the sphere of international politics is the question “Which G7 leader will leave office next?”.

Culture and Entertainment

There are prediction markets for music and video games. Examples that I found include:

• Top artist on Spotify 2026
• Dancing with the Stars Season 35 winner
• TIME’s Person of the year 2026
• Next James Bond film: Actor cast as James Bond
• Top song on Spotify 2026

Climate

OG’s climate section contains a market that you will see on most top market prediction sites. That is “Will 2026 rank among the hottest years on record?”

OG fees: What trading actually costs

In the table below, I will show you the maker and taker fees for event contracts based on category. The OG taker fee applies when you place an order that matches an existing order immediately, meaning that you are taking liquidity from the market.

As for the maker fee, it applies when you make an order or trade that is waiting for another trader, meaning you are adding liquidity to the market.

The taker fee in dollars peaks at a $0.50 contract price, while the fee as a percentage of your contract cost falls as the price rises. I have done some examples to give you an idea of the taker fees based on different contract prices. I also showed the results on the taker fee for 100 contracts.

The flat fee for commodities, equity indices, cryptocurrency and Forex pairs are a disadvantage for low-priced contracts. The $0.02 fee is 20% of a $0.10 contract, but just about 2.2% of a $0.90 contract.

OG welcome bonus and other promos

Let’s have a look at the OG welcome bonus and other promotions:

OG welcome bonus

OG offers up to $50 reward to new players. I like that this promo applies to all contract types across politics, sports, culture and other categories. To be considered eligible, register an OG account and verify your identity.

You will then need to complete $25 in qualifying trades within 7 days of verifying your account. The contract price must be below $0.80 with no sign of manipulative trading involved.

Using OG: Alpha AI and overall website features

I checked OG’s official website, and I will say that it is well-designed and user-friendly. There is a sign up/log in button on the top right for both new and registered users.

The top of the homepage contains navigation tabs that lead you to OG prediction markets related to economics, politics, commodities, climate, culture, financials and other categories. The home page contains a preview of the event contracts from the different categories and the probabilities of the potential outcomes.

I also noticed the presence of an AI assistant called Alpha. Alpha can explain price movements and building combos. It can also give you the latest information on lineups, team form and injuries in the sports category. However, it can make mistakes and should not be a substitute for your personal research.

There is a menu beside the sign up/log in button that contains links to access OG’s APIs, help center, customer support mobile apps and VIP program. You can change the website’s theme from light to dark, depending on your preference.

OG app review: iOS and Android

OG has apps for both Android and iOS. The OG’s mobile app offers the same functionalities as the desktop website. You can check for the platform’s Android and iOS apps on Play Store and App Store respectively.

In the table below, I give a detailed overview of the payment methods available on OG, as well as their minimum and maximum limits:

While OG does not charge fees for ACH transfers, fees apply to card and digital wallet deposits.

OG customer support: Getting answers fast

OG has two major sources of customer support via its help center and live chat service. I checked the help center and saw articles related to things like onboarding, funding, trading, account and security and rewards. Under each article, you will see answers to some frequently asked questions.

For the live chat, an AI chatbot will answer your questions. If need be, it will hand over your questions to a human within a few minutes.

OG is offering a ton of prediction markets across a wide range of categories in 40 US states.
