At a high level, Opinion is a onchain central-limit-order-book prediction exchange. Listed outcome formats are binary and categorical, with BNB Smart Chain supplied as the chain or hosting context; neither field answers questions about execution quality. The venue entered this dataset with a live status hint rather than a continuously monitored uptime claim. The retained research status reads "live": Official documentation describes production wallet onboarding, active CLOB trading, fees, and market resolution.

https://opinion.trade/ is the cited primary source for Opinion. Current documentation there should override any status or classification hint in this generated profile. The claims below remain limited to what the cited material supports.

For Opinion, this record preserves only the classifications binary and categorical, clob, and BNB Smart Chain. It does not convert taxonomy into claims about launch maturity, regulatory treatment, liquidity, or product quality. This boundary keeps unknown attributes visible instead of smoothing them into confident prose.

Opinion has researched access information rather than a presumption of global availability, and the official wording remains controlling. Research summary: Trading is prohibited in sanctions jurisdictions and in the United States, United Kingdom, France, Ontario, Singapore, Poland, Thailand, South Korea, China, Taiwan, and Hong Kong.

Opinion's live label should be tested against its official notices. If eligibility language is absent or ambiguous, the conservative conclusion is that access is not confirmed. KYC summary: No routine KYC process is established by the reviewed official sources; access uses wallet signatures, while the terms reserve compliance restrictions.

The mechanics snapshot for Opinion lists clob, serving markets described as binary and categorical. A label such as AMM, CLOB, or sportsbook is too broad to determine actual fills or payouts.

Opinion's market title is not enough for due diligence. Read definitions, edge cases, postponement language, resolver authority, and appeal timing before taking a position. Settlement and resolution summary: Each market page specifies its method; most markets currently use Opinion AI as the primary oracle.

Fee evidence is available for Opinion, but users should calculate total execution, funding, conversion, gas, and withdrawal cost for their exact workflow. Retained fee evidence: Takers pay a price-dependent 0%-1% fee with a $0.25 minimum; makers pay zero. The official page states a $5 minimum order and gas sponsorship for matching/settlement.

The retained material gives a custody outline for Opinion, which should be reconciled with current contracts, wallet permissions, and withdrawal documentation. Retained custody evidence: Non-custodial wallet architecture; users control signer keys and assets are held in user-controlled Safe wallets.

Opinion should be approached as a risk-bearing venue, not a source of guaranteed probabilities. Its live hint can become stale and must be reconciled with current official notices. Documented limitations include: Broad regional exclusions, $0.25 minimum can dominate small trades, and Most resolutions depend on a proprietary AI oracle.
