What Is OPINION?

​

Quick Answer

​

Key Takeaways

• OPINION is the ecosystem; Opinion.trade is its live prediction-market application.
• A market price can be read as the market’s current implied probability, not as a guaranteed forecast.
• Most markets currently use Opinion AI as the primary oracle, but the exact resolution method is written into each market’s rules.
• The official architecture describes four connected layers: Trade, AI, Metapool and Protocol.
• OPN is described as a utility token. Token status, supported contracts and available features should always be checked through current official channels.

​

OPINION, Opinion.trade and “Opinion” Are Not Three Different Products

The naming is easiest to understand as a hierarchy: This distinction matters for search and security. Someone looking for the “Opinion prediction market” usually wants the trading app, while someone researching “OPN” may be looking for token information. Start with the verified list of official Opinion links, especially before connecting a wallet.

​

How the Opinion Prediction Market Works

A prediction market turns a question about a future event into tradeable outcomes. For a binary market, traders typically choose Yes or No. A Yes share priced at 0.65 can be interpreted as the market collectively assigning roughly a 65% probability to Yes at that moment. The price is not Opinion’s editorial prediction. It changes as participants place and fill orders. The basic lifecycle is:

1. A market is published with a question, closing time, resolution rules and source criteria.
2. Traders buy or sell outcome shares through an order book.
3. Prices move as orders are matched and information changes.
4. A trader can sell before resolution or continue holding the position.
5. The market is resolved using the method stated in its rules; winning outcome tokens settle according to those rules.

The Four Layers of the Opinion Stack

The current OPINION Docs and the February 2026 whitepaper describe a four-layer stack.

​

1. Opinion.trade: the exchange

Opinion.trade is the user-facing application. It provides markets, charts, rules, an order book and portfolio controls. Markets cover real-world events across categories visible in the live app. The exchange uses a central limit order book model. A market order can execute immediately against available liquidity; a limit order waits for another participant to accept the chosen price. Current fees and minimums can change, so the order confirmation and official fee page should be treated as authoritative.

​

2. Opinion AI: market creation and resolution

Opinion AI is described as a decentralized, multi-agent AI oracle for complex or unstructured information. It has two related jobs:

• help turn a topic into precise, objective and resolvable market rules;
• evaluate evidence when the market reaches resolution.

The official resolution page says most markets currently use Opinion AI as the primary oracle. That does not mean every market follows one universal process: users should read the named sources and resolution method on the specific market page. See How the Opinion AI Oracle Works for the full explanation.

​

3. Opinion Metapool: unified liquidity infrastructure

Opinion Metapool is the stack’s liquidity layer. The stated goal is to reduce fragmentation across individual markets or venues and support deeper liquidity and shared resolution trust. It is useful to distinguish architecture from live user features. The official materials describe the role of Metapool in the stack; they do not imply that every planned cross-market capability is already available in the app today.

​

4. Opinion Protocol: interoperability

Opinion Protocol is described as a universal token standard intended to make prediction-market positions interoperable across venues. In plain language, the goal is for outcome assets and market infrastructure to be usable beyond one isolated interface. As with Metapool, readers should separate the protocol’s design goal from the set of integrations currently shipped.

​

What Is OPN?

OPN is the utility token described for the Opinion ecosystem. The February 2026 whitepaper specifies a fixed total supply of one billion and describes Ethereum Mainnet and BNB Chain support through LayerZero’s OFT standard. The utility areas described in official materials include:

• access to certain data products, dashboards or oracle feeds;
• product privileges, account tiers or fee-related features;
• participation in protocol and oracle governance mechanisms;
• alignment of incentives across ecosystem participants.

These descriptions are not a promise that every utility is active in every product. The whitepaper itself was published before issuance and captured the status at that time. For current token availability, the correct contract address and live utilities, use only up-to-date links from the official website, Foundation or documentation. A ticker symbol alone is not enough to identify an authentic token. OPN is not an equity interest in Opinion Labs, and this guide does not assess its value or provide investment advice.

​

What Makes Opinion Different?

Opinion’s clearest architectural distinction is the attempt to connect three things in one stack:

• a tradeable market for expectations;
• AI-assisted rule formation and resolution for questions that may involve unstructured evidence;
• on-chain assets and infrastructure intended to support composability.

That combination broadens the kinds of questions a prediction market can attempt to list, but it also makes careful market wording and transparent evidence especially important. An AI oracle does not remove ambiguity automatically; good resolution begins with a question that can be answered under explicit rules.

​

Is Opinion.trade Legit?

Opinion.trade has a live application, public documentation, published technical materials and linked third-party smart-contract audits. These are useful verification signals, but none eliminates trading, liquidity, smart-contract, wallet, resolution or jurisdiction risk. Our separate due-diligence guide explains whether Opinion.trade is legit and what users should verify.

​

Where Opinion Fits

Opinion sits at the intersection of prediction markets, AI oracles and on-chain financial infrastructure. The live exchange is useful to traders who want to express a view on an event or read market-implied probabilities. The wider stack is relevant to developers, market creators and applications that want prediction data or conditional assets. The blog explains concepts and use cases; docs.opinion.trade remains the authoritative source for current product instructions and developer details.

What to Watch

• Which Metapool and Protocol capabilities move from architecture into live production.
• How market-specific resolution rules and dispute processes evolve.
• Which OPN utilities are live, and where they are documented officially.
• Changes to supported networks, fees, minimums and account methods.
• New OpenAPI, WebSocket and CLOB SDK capabilities for builders.
