Trade: Highest temperature in Karachi on June 2?

Market context

Karachi will experience peak temperatures on 2 June 2026, with the highest reading recorded at Masroor Airbase Station determining the settlement outcome. The market currently shows 0% implied probability across all temperature ranges on Polymarket's order book, indicating either minimal trading activity or a technical issue with pricing. Settlement will reference historical weather data from Weather Underground, the designated resolution source, with the settlement window closing at midday UTC on the resolution date.

Karachi's June temperatures typically range between 38–42°C, based on thirty-year climate normals from the Pakistan Meteorological Department. The city experiences pre-monsoon heat during early June before the southwest monsoon arrives, generally in mid-to-late June. Historical data from 2015–2024 shows June peaks consistently exceeding 38°C, with several years recording maxima above 42°C. The 0% probability across all ranges suggests traders have not yet engaged with this market or are awaiting clearer atmospheric forecasting models as the settlement date approaches.

Traders should monitor Pakistan Meteorological Department advisories and monsoon onset timing, which influences early-June heat intensity. Urban heat island effects at Karachi's airport station and any unusual atmospheric patterns—such as early monsoon arrival or heat wave conditions—will shape actual temperatures. Current seasonal forecasts and real-time weather models from international centres will become increasingly relevant in May 2026 as traders reassess probability distributions ahead of settlement.

Resolution source

This market settles from the official outcome published at https://www.wunderground.com/history/daily/pk/karachi/OPKC. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.

How to trade this market step by step

The mechanics for trading "Highest temperature in Karachi on June 2?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.

1. Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
2. Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
3. Pick a side. Buy YES if you believe the event will happen; buy NO if you think it won't. The current YES price reflects the market's collective probability.
4. Size your position. If you stake 100 USDC at 50% YES, you'll receive shares that pay $200 if YES resolves true — a 100% gross return. If NO resolves, your shares are worth $0.
5. Set risk controls (optional). Stop-loss, take-profit, and limit-order types all supported. Use the trade ticket's slippage box to cap your maximum entry price.
6. Wait for resolution. When the event resolves on-chain via the UMA optimistic oracle, the winning side settles to 100¢ automatically and USDC hits your balance within seconds. Withdrawable to any wallet you control.

How active is this market?

$25K in lifetime turnover and $0 of resting liquidity puts this market in the around the median by volume for weather contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.

Last 24 hours alone saw $15K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.

The market has been open for under a month — fresh enough that information asymmetry remains a real factor.

Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.

Key terms

YES / NO share

A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.

CLOB

Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.

Liquidity

USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.

UMA optimistic oracle

The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.

Slippage

The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.

Conditional token

ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Frequently asked questions

Risk and regulatory note

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.

Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
