At a high level, Ideosphere is a human-versus-AI forecasting research platform. Listed outcome formats are binary, categorical, and scalar, with Base 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": The official site describes recurring monthly epochs, curated questions, market resolution, leaderboards, and published results.

https://ideosphere.io/ is the cited primary source for Ideosphere. 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.

A careful comparison should keep Ideosphere's three supported dimensions separate—formats (binary, categorical, and scalar), mechanics (futarchy), and chain context (Base). None supplies evidence about profitability, legal availability, depth, or security. This boundary keeps unknown attributes visible instead of smoothing them into confident prose.

Ideosphere may apply geographic and account restrictions that are not captured here. Eligibility should be established from current official terms before any identity, wallet, or payment information is provided. Research summary: No geographic eligibility rules are published.

Ideosphere'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: Unknown; reviewed sources did not establish KYC requirements, so consult current onboarding and legal terms.

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

Primary rules control outcomes on Ideosphere. Save the version reviewed and note the named data source, decision authority, challenge process, and timing before committing funds. Settlement and resolution summary: Questions are curated and markets resolve during monthly epochs; exact sources, scoring, appeals, and payout rules are not published on the cited page.

Ideosphere may change fees, limits, and verification requirements by product or jurisdiction. Because those conditions were not verified, the conservative values in this record remain "check official source." Retained fee evidence: Unknown; reviewed sources did not establish current fees or total transaction costs, so consult the official schedule.

Ideosphere's custody and settlement arrangements are also unknown. The Base chain label does not prove self-custody, identify deployed contracts, name collateral, or explain who controls withdrawals and final settlement. Retained custody evidence: Unknown; the public page does not establish deposits, prize custody, or withdrawal mechanics.

Ideosphere 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: Not established as a conventional cash prediction exchange., Fees, prizes, and custody are unclear., and Question-level resolution and appeal rules are not public..

Revisit https://ideosphere.io/ before acting on Ideosphere. Preserve relevant terms and market rules, confirm support contacts, and use a small test only after the custody and settlement path is understood. Priority evaluation checks include: Confirm whether participation uses real money, prizes, or points., Read epoch scoring and leaderboard rules., Inspect each question's resolution source., and Confirm data access and reuse terms..
