How Polymarket BTC 5-Minute Markets Settle

The title identifies the question; the rules decide it

Fast crypto markets often have nearly identical titles. The safe starting point is the full rule text attached to the exact market identifier. It defines the eligible window, source, comparison and treatment of edge cases.

Polymarket’s general resolution documentation makes the same distinction: the title describes the market, while the resolution rules define how it resolves. A five-minute tool should therefore preserve the rule source beside the live observation rather than hiding it in a separate page.

Four fields that must agree

1. Start time: when the reference or comparison window begins.
2. End time: when the outcome becomes eligible for determination.
3. Reference source: the named feed, index or rule source.
4. Comparison: whether the ending value must be above, below or otherwise compared with the opening reference.

Timezone conversion is part of the market identity. A correct price attached to the wrong five-minute boundary is not a small timing error; it describes another round.

What “price to beat” means

The price to beat is the baseline that separates the outcomes under the rule. BTC distance is then calculated as the current eligible reference minus that baseline. A positive distance does not by itself guarantee UP, because the window is not finished and the reference may change before the boundary.

The reference value should carry both its source timestamp and quality state. A cached number without age can look live long after it has stopped being useful.

Why exchange prices and reference values can differ

A Binance trade, an exchange midpoint and a Chainlink feed answer related but different questions. They can update at different times and use different aggregation methods. A source that is useful for market context may not be the source named in the resolution rule.

That is why a decision workspace should label provenance. It can show exchange pressure and cross-market movement as supporting evidence without silently substituting them for the official settlement reference.

How to handle uncertainty

A disciplined system uses visible states such as VERIFIED, PROVISIONAL, STALE, CONFLICT and UNAVAILABLE. It should never turn a missing reference into zero or preserve a last-known value without showing its age.

• Verified: identity, timing and source agree.
• Provisional: useful but awaiting an independent check.
• Stale: the value is older than the decision permits.
• Conflict: independent observations disagree.
• Unavailable: the required fact cannot be supported.

Settlement checklist before reading direction

• Confirm the condition or market identifier.
• Confirm start, end and timezone.
• Read the complete resolution rule.
• Identify the named reference source.
• Verify the opening reference and its precision.
• Check the current source timestamp and quality.
• Keep contextual exchange prices separate from the deciding reference.

Only after these checks should distance, contract prices, flow or wallet activity influence the directional case.
