The Shortest Useful Answers

​
Product and Account Questions

Opinion.trade is the live prediction exchange within the broader OPINION ecosystem. Users buy and sell shares tied to possible outcomes of real-world events. The wider stack also includes Opinion AI, Opinion Metapool and Opinion Protocol. Start with What Is OPINION? for the full entity map.
Not exactly. OPINION refers to the wider ecosystem and technology stack. Opinion.trade is the user-facing exchange. Opinion AI is the market-definition and oracle layer. OPN is the utility token described for the ecosystem.
The verified live application is app.opinion.trade. The main domain is opinion.trade, the product documentation is docs.opinion.trade and this learning center is blog.opinion.trade. Use the maintained official-links directory before connecting a wallet or account.
Current official Docs describe two routes: connect a Google or X social account, or connect a supported Web3 wallet. Follow the options displayed in the verified app because supported methods can change. Never provide a seed phrase or private key to log in.
Not necessarily. The current social-account guide also describes Google and X connection. If you use a wallet, review every connection and signature request and verify that it comes from app.opinion.trade.

Trading and Price Questions

A market defines a question, possible outcomes, closing time and resolution rules. Traders place orders to buy or sell outcome shares. Prices change as orders match and information changes. After the event, the market is resolved under its published rules and the winning outcome settles accordingly.
It is commonly interpreted that way. The official price guide says a Yes share at 65c suggests an implied probability of about 65% based on current trading activity. It remains a market signal—not a promise that the event will happen.
A market order prioritizes immediate execution against available liquidity. A limit order specifies the price you will accept and may wait, fill partially or never fill. In both cases, review the order preview, spread, depth, quantity, fee and maximum loss before confirming.
Yes. Official Docs state that a filled position can be bought or sold before the market closes. The price you can obtain depends on available liquidity and the order book, so an early exit is not guaranteed at the displayed last price. Read Trade Before Resolution.
Yes. If you hold a losing outcome through final resolution, its settlement value may be zero. Selling earlier may reduce or realize a loss, but depends on liquidity. Use only an amount you can afford to lose.

​
Fees, Minimums and Liquidity

The current official policy charges takers while makers are generally not charged. The taker rate follows a market- and price-sensitive curve and can be affected by discounts and a minimum fee. Read Opinion Fees Explained, then verify the live order preview and official fee page.
As reviewed on September 2, 2026, official Docs list a 5minimumorder∗∗,∗∗5 minimum order**, **0.5 minimum fee and $5 minimum withdrawal, subject to change during abnormal network conditions. The live interface is the current source of truth.
The displayed or last-traded price does not guarantee that enough shares are available there. A market order can fill across several prices. The spread and order-book depth determine the actual execution cost. See Order Books, Spreads and Liquidity.

​
Resolution and Opinion AI

Each market page specifies its own resolution method, evidence and exceptional-case rules. Current official Docs say most markets use Opinion AI as the primary oracle. Read the exact market rules rather than assuming every market follows one universal process.
Opinion AI helps at both ends of the market lifecycle: it can assist with precise, resolvable market rules before trading and evaluate relevant evidence when an outcome must be determined. The public architecture also describes multiple models or agents, trusted execution environments and human review. See How the Opinion AI Oracle Works.
The current product documents a time-limited dispute process after a result is proposed. A user should read the market page and current resolution and dispute guide before the window closes; old screenshots or summaries may not reflect the controlling process.

​
Safety, Availability and Access

Opinion.trade has a live product, public documentation, technical materials and linked third-party smart-contract audits. Those are meaningful verification signals, but they do not remove trading, liquidity, wallet, smart-contract, resolution or jurisdiction risk. Use the evidence-based Is Opinion.trade Legit? checklist.
No trading platform should be described as risk-free. Verify the domain, review current audits and Terms, understand the account or wallet model, read every market’s rules and confirm each transaction. The custody and fund-safety guide separates platform controls from user responsibilities.
Availability depends on current Terms, age requirements, product controls and jurisdiction. Do not infer eligibility from whether a webpage loads. Check Where Is Opinion.trade Available? and the controlling Terms before using the product.
Developers should use docs.opinion.trade for the current Open API, WebSocket and CLOB SDK documentation. This Blog explains concepts for users; the developer Docs are authoritative for endpoints, authentication, models and integration details.
