Approval rating markets and aggregator sources

Some event contracts ask where a leader's approval rating will stand on a date — above a threshold, or within a bracket. These usually settle on a named polling aggregator, not on any one poll. SoftCta literacy starts with the aggregator's methodology and the snapshot rule. Pair with prediction markets vs opinion polls.

Why aggregators differ

Polling averages from different publishers can disagree on the same day because they:

• Include different polls. Some exclude pollsters with poor track records or undisclosed methods.
• Weight differently. By recency, sample size, pollster rating, or population (adults vs registered or likely voters).
• Adjust for house effects. Some correct for pollsters that lean consistently one way.
• Update on different schedules. Some refresh several times a day; others less often.

A contract that names one aggregator settles on that aggregator alone. Another venue's similar contract may name a different source — compare definitions before comparing prices.

Snapshot timing and rounding

Read the as-of rule closely (timezone and as-of rules):

• At what exact time and timezone is the figure taken?
• Is it the figure displayed on a page, a downloadable dataset, or an archived copy?
• How many decimals count? A 44.95 displayed as 45.0 can decide a bracket (strike prices on brackets).
• What happens if the page is unavailable or the publisher changes its method mid-window?

How a new poll moves an average

An average moves when polls enter or leave its window. A single outlier poll may shift a simple average more than a weighted one. Readers sometimes look at which polls are scheduled to release before the snapshot, but publication times are not always announced, and the aggregator decides whether to include them.

Revisions and late polls

Aggregators occasionally add a poll after the fact or correct an entry. Whether that counts depends on the contract — see data revisions and restatements and verifying official settlement sources. Screenshots with timestamps help you document what the source showed at the snapshot.

Reading the price

Convert bracket prices with the implied probability tool and check that adjacent brackets sum sensibly. A price is a view on where the aggregate lands, which blends opinion about polls with frictions; it is not itself a poll.

A worked example

Imagine a contract on whether a named aggregator's approval figure is at or above 45.0 at noon Eastern on a Friday. On Thursday evening the displayed figure is 44.9. Overnight, a new poll is added and the average shows 45.1 by morning; at 11:50 a.m., another poll enters and the figure returns to 44.9. The snapshot rule decides the result, not the morning reading. If the aggregator later adds a poll dated before the snapshot, the contract's revision rule determines whether the outcome changes. Saving timestamped records at the snapshot helps you follow the settlement later.

Failure modes

Comparing one poll with a contract that settles on an average. Ignoring the rounding rule near a boundary. Assuming two venues' approval contracts use the same aggregator. Substantial risk of loss.

Closing SoftCta checklist

• Re-read the venue definition in your own words before reacting to a price.
• Convert prices with fee and spread awareness; verify live cents on the operator.
• Prefer primary settlement sources over secondary headlines and social summaries.
• Treat ChanceWire hubs, movers, and tools as orientation — not order entry.
• Confirm age, location, and product eligibility; SoftCta pages will not suggest location spoofing.
• If clarity is incomplete, watching is a complete SoftCta outcome — no pick-selling urgency required.

SoftCta habits

• Name the aggregator before reading the price.
• Note snapshot time, timezone, and decimals.
• Check how late polls and revisions are treated.
• ChanceWire does not execute trades.
• Verify live prices and rules on the operator.
