Highest temperature in Toronto on August 12?

Platform comparison

Market context

On 12 August 2026, the highest temperature recorded at Toronto Pearson International Airport will fall into one of several defined ranges, measured in degrees Celsius and sourced from Weather Underground's Daily Observations table rather than the Day High & Low summary. Toronto's August climate typically ranges from 20–27°C, though heat waves can push readings above 30°C. The settlement window closes at midday UTC on that date, meaning observations recorded after the market's cut-off will not affect resolution.

Historical August temperatures at Toronto Pearson show considerable year-to-year variation. The station recorded 31.5°C on 12 August 2012 and 29.1°C on 12 August 2019; conversely, cooler years such as 2015 saw a high of only 22.8°C on that date. This volatility explains why the crowd currently assigns zero probability to any single outcome—the range of plausible outcomes is genuinely wide. Comparable weather prediction markets typically see probability mass distributed across three to five adjacent temperature bands rather than concentrated in one, reflecting genuine meteorological uncertainty two years in advance.

Traders should monitor Environment and Climate Change Canada's seasonal forecasts and any announced changes to Toronto Pearson's weather station instrumentation or relocation. The resolution source's specificity—Daily Observations rather than the summary table—matters operationally; discrepancies between the two have occurred historically and will determine settlement. Under German GlüStV regulations, this market may face restrictions depending on the operator's licensing status. US CFTC oversight applies if the platform operates with US customers; most no-KYC thresholds (typically $1,500 USD equivalent) would permit entry into this single-event weather market without identity verification, though aggregate exposure across multiple markets may trigger compliance requirements.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Is Kalshi Legal in California has a different geo footprint.

Do I need to KYC for Is Kalshi Legal in California?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
