How PlayPicks compares prediction markets

Contract identity, timestamps, costs, and human review are the basis of a useful comparison.

Match the contract before comparing its price

A similar title is not a match. Each comparison records the underlying event, outcome, threshold, timeframe, resolution source, and material cancellation rules. Stable provider IDs identify the records. A named reviewer records the equivalence decision and its evidence.

A lowest-price claim has a narrow meaning

Only executable quotes for the same side and stated size can support a lowest-price claim. The comparison must include fees, bid/ask spread, available depth, and the named venues checked at the displayed time. Missing fees or depth make the comparison incomplete.

Prices stay in stable source order. Affiliate compensation does not set the order. Dollar turnover and contract counts remain separate, and routed liquidity is not counted twice.

How we label out-of-date prices

If an update fails, the page keeps the last recorded value with its original time and labels it as out of date. A value is never shown as live when it is not.

How we build price history

A price history chart uses only recorded values with a known source. Gaps stay as gaps: no value is filled in or estimated. Resolved events keep their page, final result and settlement source.

Documentation, observations and testing answer different questions

Product documentation tells us what a provider describes. A recorded market observation records what the source displayed at a particular time. A hands-on test describes what a named tester experienced under stated conditions. We identify these evidence types instead of presenting one as another.

Source-based research can explain a documented charge or account restriction. It cannot establish how consistently a service performs or how quickly a different person will receive funds. Third-party test observations retain their original attribution and circumstances.

What happens when a comparison is incomplete

Missing values remain unavailable. We do not estimate an unknown fee from another product, infer a current quote from an older capture or treat no observation as a zero. Related contracts remain related until their material settlement conditions match.

Readers should be able to follow a conclusion back to its evidence. Source links, observation times and the reasons for excluding a comparison therefore belong next to the finding rather than in an unexplained score.

Important information

In the United States, certain event contracts are offered through Designated Contract Markets (DCMs) subject to oversight by the Commodity Futures Trading Commission (CFTC). Regulatory arrangements and product availability differ between platforms and jurisdictions. CFTC oversight does not constitute approval or endorsement of any particular contract. Event contracts are derivatives products, not sports betting or gambling products, and are not licensed by any state gaming or gambling regulator.

Trading event contracts involves substantial risk of loss. You may lose some or all of the funds you use to trade. Past results do not guarantee future outcomes.
