How to verify official settlement sources

Event-contract prices move on rumors, polls, and dashboards. Settlement usually hangs on a narrower object: the official source named in the rules. This SoftCta guide is a verification checklist so you can confirm that source before treating a mid as meaningful. Informational only — not pick-selling.

Core companions: resolution criteria checklist, self-reported data vs official print, and dispute windows.

Step 1 — Find the named source in the rules

Open the venue’s market page and locate resolution criteria. Highlight:

• the organization or feed named as authoritative,
• any URL, dataset name, or document title,
• fallback sources if the primary is unavailable,
• and the timestamp or “as of” language.

If the UI summary is shorter than the full rules, open the full rules. UI chips are not a complete contract.

Step 2 — Open the primary page yourself

Do not stop at a screenshot in comments. Navigate to the agency, league, court, or data vendor page. Confirm:

• you are on the official domain (watch for look-alike sites),
• the release matches the vintage the contract names,
• and the metric definition matches the Yes condition.

For oracle-mediated crypto venues, also read how proposals and challenges work — oracles and UMA-style resolution.

Step 3 — Match definitions, not vibes

A CPI market that settles on a specific index and seasonality is not “inflation vibes.” An election market that settles on a named call or certification is not “who people think won on social media.” Write the Yes condition in one sentence using only words from the rules, then check that the official page speaks those words.

The glossary quiz helps if settlement vocabulary is unfamiliar.

Step 4 — Check revisions, corrigenda, and timing

Many official prints revise. Courts amend dockets. Leagues correct box scores. Contracts differ on whether the first print or a later revision binds. Read settlement timing and payout windows alongside the market’s own clock.

Record the retrieval time in a consistent zone (Asia/Nicosia works for ChanceWire notes) and keep the URL.

Step 5 — Know the dispute path

If the source is ambiguous, venues may offer a dispute or clarification window. That process is part of verification literacy: know who decides, on what timeline, and what evidence they accept. Unofficial tallies can be early and wrong relative to the final named print.

A short verification template

Copy this into your notes:

• Market title and venue URL
• Exact Yes sentence
• Named source + link
• As-of / revision rule
• Dispute window (yes/no + link)
• What I observed on the official page (quote or figure, with time)

SoftCta close

ChanceWire does not choose settlement sources and does not execute trades. Verifying the official source is slow on purpose. That slowness is the point: prices are fast; rules are precise. SoftCta only.

Cross-venue source mismatch

Two venues can cover the same headline with different named sources. One may settle on an agency print; another may settle on a secondary data vendor or a media call. Before you call prices “the same market,” verify both source lines. A gap between mids can be a definition gap, not an inefficiency story.

If you maintain notes across Polymarket and Kalshi-style products, keep separate source fields. SoftCta comparison media does not merge them for you.

Where ChanceWire fits

ChanceWire helps readers browse, compare, and learn. It does not execute trades or turn a literacy note into a personal recommendation. Review markets, then verify the operator’s current rules, fees, eligibility, and settlement source before making any decision. Informational market literacy is useful even when you do nothing with the quote.

A calm SoftCta checklist

• Read the venue rules before comparing a price.
• Treat displayed probability as an estimate, not a promise.
• Account for fees, spread, liquidity, and settlement timing.
• Confirm age, location, and product eligibility on the venue.
• Use ChanceWire to browse and compare; it does not execute trades.
