As of Oct 23, 2026Measured from Sep 23 to Oct 23, 2026

We publish a grade once this market has 30 days of observed data.

Grade limits apply: D from the weaker of liquidity and integrity, C+ from trading evidence.

Rates how well this market trades, from A+ (best) to F: how much you can trade near the price, and how many different traders take part. Not a forecast of the outcome.

Liquidity and integrity

The two measures behind the grade.

Liquidity

Shown with the grade

How easily the market trades: the depth of buy and sell quotes, the cost of a typical trade, and how steadily trading happens.

Integrity

Shown with the grade

How broad and orderly trading is: how many different traders take part, and how often quotes are missing, one-sided, or crossed.

It screens for concentrated trading. It is not proof that a market can’t be manipulated, since many accounts can belong to one trader.

Both are recalculated daily over the same 30-day period. The overall grade moves more slowly: a change has to hold before it counts.

How grades are calculated ↗

Market Grades are in beta. Grades are live, and the methodology is being validated in public on a published schedule. Validation roadmap ↗

Disclosures

Market Grades measure market quality – liquidity, integrity – not the likelihood of any outcome.

Market Grades are unsolicited: no graded party requests, pays for, or previews a grade. Belief Systems holds no positions in graded markets.

A grade is not a recommendation to buy, sell, or hold any position, and is not a substitute for a user's own assessment.
