The Reliability Layer for Prediction Markets

Know which prediction markets to trust.

Prediction-market prices are becoming public signals — used by funds, journalists, analysts, and risk teams. But a market price is not automatically reliable. Beatpoly adds the missing layer: resolution risk, liquidity quality, cross-venue equivalence, and market integrity, scored per market.

Built for funds, compliance teams, media desks, research firms, and data platforms using prediction-market signals professionally.

Reliability profile example
Will X happen before June 30?
Polymarket · Macro · 64%
C
Resolution Risk
Elevated (72)
Execution Risk
Medium (48)
Cross-Venue
Not equiv. (41)
Abnormal Flow
Elevated (69)
Key risk: Subjective resolution wording; large move without confirmed public catalyst; thin depth near mid-price.

Score convention:   Risk scores (resolution risk, abnormal flow) run 0–100 where higher = more risk.    Quality scores (liquidity quality) run 0–100 where higher = stronger quality.    The composite A–F reliability rating converts all dimensions into one directional signal.

The problem

Raw odds are not enough.

A market showing 64% does not necessarily mean the world has a reliable 64% probability of that outcome.

The price may reflect shallow liquidity. It may be moved by one wallet. It may depend on a single data source. It may resolve under wording that looks simple but creates edge-case risk. Or it may be reacting to information that is not yet public.

Professional teams need to know more than the price. They need to know whether the price can be trusted.

Beatpoly turns market prices into reliability intelligence.
Resolution ambiguity
Vague wording, subjective criteria, or single-source dependency can make settlement contested regardless of the price.
Insider information flow
Markets can move before public announcements. A price spike without a public catalyst is a signal — but not the one most users think it is.
Fake cross-venue arbitrage
Similar markets on different platforms often resolve against different sources, dates, or criteria. Apparent arbitrage is usually not arbitrage.
Execution cost destruction
Taker fees, spread, and slippage can consume the entire edge. A 4-point opportunity with 5-point friction is a losing trade.
The Beatpoly Reliability Engine

Four dimensions. One reliability rating.

Every monitored market is evaluated across four practical dimensions. Each score is machine-readable, explainable, and API-accessible.

📋
01 — Resolution Risk

Does this market resolve cleanly?

Measures whether the contract can settle without ambiguity, dispute, or source failure. We evaluate wording, oracle mechanism, settlement timing, source fragility, and the potential for data-source manipulation.

Resolution Risk Score Source Fragility Flag Ambiguity Flag Oracle / Data Source Notes
Example: Two markets may both ask whether a city reaches a certain temperature. If one resolves against an airport station and the other against a city-centre station, they are not the same market — and the risk profiles differ significantly.

📈
02 — Liquidity & Execution Quality

Does the edge survive execution?

Measures whether the displayed price is actually usable. We evaluate spreads, order-book depth, recent trade concentration, estimated slippage, fee sensitivity, and maker/taker friction at professional position sizes.

Liquidity Quality Score Spread Risk Estimated Slippage Execution Cost Estimate
Example: A 62% market with a wide spread and shallow depth may be less useful than a 59% market with deep liquidity. The price is not the only input to usability.
Execution cost methodology →
03 — Cross-Venue Equivalence

Are two similar markets the same bet?

Measures whether similar-looking markets across Polymarket and Kalshi are actually equivalent. We compare wording, resolution source, cutoff date, dispute process, oracle design, and category-specific edge cases.

Equivalence Score Arbitrage Safety Flag Wording Differences Source Differences
Example: A price gap between Kalshi and Polymarket is not automatically arbitrage. If the markets resolve under different rules, the gap is compensation for hidden basis risk — not free money.

🔎
04 — Market Integrity & Abnormal Flow

Is the market showing abnormal activity?

Measures whether market movement looks unusual, concentrated, or disconnected from public information. We monitor sudden moves, new-wallet concentration, pre-announcement behavior, liquidity shocks, and clustered trades.

Abnormal Flow Score Concentration Flag Pre-Catalyst Alert Integrity Risk Summary
Example: If a market moves sharply before a public announcement and the activity is concentrated in a small set of wallets, the price may reflect information that is not yet broadly public — which carries both intelligence value and integrity risk.

Example output

From raw market price to reliability intelligence.

Beatpoly does not just return the latest price. It explains whether the market is usable, risky, distorted, or worth monitoring.

The reliability rating answers

AHigh reliability — clear rules, strong liquidity, clean flow
BUsable with context — some limitations present
CCaution — meaningful weakness in one or more dimensions
DHigh risk — price may be distorted, thin, or ambiguous
FUnreliable — severe resolution, liquidity, or integrity risk

Why now

Prediction markets are becoming infrastructure.

Prediction-market data is moving beyond retail trading. It is being used by journalists, analysts, investors, builders, and risk teams as a real-time signal for politics, macro events, culture, weather, and public decision-making.

As the category grows, the question is no longer only "What is the market price?" The more important question is: Can this market price be trusted?

The regulatory surface is also expanding. Enforcement cases involving insider trading, candidate self-betting, and alleged classified-information use have made prediction-market integrity a live compliance issue.

Prediction-market data is now embedded in mainstream media workflows via API. Reliability context is essential for responsible editorial use.
The CFTC issued an enforcement advisory identifying insider trading, market manipulation, and abusive practices as active concerns in regulated event-contract markets. Earlier, in January 2022, the CFTC settled charges against Polymarket (Release No. 8478-22).
Three U.S. congressional candidates were fined and suspended by Kalshi for wagering on their own election outcomes — a compliance case with direct institutional implications. (AP, April 2026)
Weather market source-fragility risk
Weather markets can carry single-source data risk when a contract resolves against one station, one measurement method, or one official feed. Beatpoly treats this as source-fragility risk inside the Resolution Risk dimension.
FAQ

Common questions

What is prediction-market reliability?+

Prediction-market reliability measures whether a market price is useful and trustworthy for professional use. A reliable market has clear resolution rules, sufficient liquidity, low distortion, clean information flow, and limited settlement ambiguity. Beatpoly scores each dimension separately so teams understand exactly where risk is concentrated.

Does Beatpoly provide trading signals or investment advice?+

No. Beatpoly provides market reliability intelligence, risk scoring, and data-quality analysis. It is designed to help professional teams evaluate markets — not to provide personalized investment advice. A high-reliability rating does not mean a market is a profitable trade. It means the market's price is clean enough to use as a professional signal.

Which prediction-market platforms does Beatpoly cover?+

Beatpoly currently covers Polymarket and Kalshi, with additional venue coverage expanding as the platform matures. Cross-venue equivalence analysis requires at least two venues and is most useful where similar markets exist on both Polymarket and Kalshi simultaneously.

Does a C or D rating mean the market is wrong?+

No. A lower reliability rating means the market price is harder to use or defend in a professional context — not that the market's directional information is necessarily incorrect. A thin, ambiguous, or abnormal market can still contain real information. The rating tells you how much caution to apply when relying on it.
