Prediction markets let participants take positions on the outcome of real-world events, with market prices reflecting the collective probability assigned to each outcome. Opinion is a high-performance prediction exchange that brings this concept on-chain, combining a live trading exchange with AI-driven market resolution and decentralized finance (DeFi) composability. This article explains what Opinion is, how the platform works, what the OPN token does, and how OPN is available on Binance.
What Is Opinion?
Opinion is a decentralized prediction exchange designed to transform economic and real-world insights into tradable markets. The platform allows users to create, trade, and resolve markets on outcomes including macroeconomic indicators, news events, and sports results. To date, Opinion has processed over $23.6 billion in cumulative prediction volume.
The platform is built around a layered architecture called the Opinion Stack, consisting of four components.
Opinion.Trade
Opinion.Trade is the live exchange where all trading and market creation takes place. It uses a central limit order book (CLOB) for real-time order matching, a dedicated Sports trading interface, real-time dashboards, and social features that let you follow other traders. The platform offers a 50% maker rebate paid daily in USDT, and competitive fees designed to reduce friction for active participants.
Opinion AI
Opinion AI is described as the first decentralized multi-agent AI oracle capable of resolving complex, unstructured data. Rather than relying on a single data source, Opinion AI uses a network of agents to parse real-world information and determine market outcomes via smart contracts. Opinion AI also assists with market creation: it helps users generate clear, objective rules and verifies whether a proposed topic is resolvable before the market goes live, supporting permissionless market creation at scale.
Opinion Metapool
The Opinion Metapool is a unified liquidity infrastructure that pools capital across markets rather than isolating it in separate pools. By aggregating liquidity across prediction venues, the Metapool is designed to support deeper order books and more reliable market resolution.
Opinion Protocol
The Opinion Protocol is a universal token standard that enables interoperability between Opinion and other prediction platforms. It is designed to allow OPN to function across a broader ecosystem of prediction venues rather than remaining confined to a single platform.
Using Opinion.Trade
To access opinion.trade , you’ll need to connect a compatible Web3 wallet.
You can do this by clicking on the [Connect Wallet] button on the top right of the homepage.
Once connected, you can browse open markets, view live order books, and take “Yes” or “No” positions on event outcomes. Market prices run from 0 to 1, representing the collective probability that a given outcome will occur. A price of 0.7 on a “Yes” position, for example, indicates the market currently prices that outcome at 70% likely.
You can also create a market by proposing an event along with a set of resolution rules. Opinion AI reviews the rules for clarity and resolvability before the market goes live, reducing the likelihood of ambiguous or unresolvable outcomes.
If you believe a resolved outcome is incorrect, the platform's Dispute System lets you stake OPN to challenge the result. Staking OPN to accurately defend or dispute an outcome creates a community-driven verification layer for market resolution.
What Is the OPN Token?
OPN is the native utility token of the Opinion ecosystem. It has a fixed total supply of 1 billion tokens and serves three core functions: governance (voting on protocol upgrades and parameters), incentives (earning rewards as a trader or liquidity provider), and dispute resolution (staking OPN to verify or challenge market outcomes).
The token allocation at launch breaks down as follows:
Community/Airdrops: 23.5% (235M OPN), with 3.5% released at Token Generation Event (TGE) and the remainder vesting over seven months.Investors: 23% (230M OPN), subject to a 12-month cliff followed by 24-month linear vesting.Team and Advisors: 19.5% (195M OPN), on the same 12-month cliff and 24-month linear vesting schedule.Foundation: 12% (120M OPN).Ecosystem and Incentives: 11.1% (111M OPN), with a partial unlock at TGE.Marketing: 8.9% (89M OPN).
Approximately 19.85% of the total supply (198.5M OPN) was unlocked at TGE. Investor and team allocations are subject to a 12-month cliff, meaning those tokens are not released until approximately Q1 2027, followed by a 24-month linear vesting period.
