Trade: Highest temperature in Tel Aviv on June 1?

Market context

On 1 June 2026, the highest temperature recorded at Ben Gurion International Airport will fall within one of several defined ranges. The market settles based on NOAA's official temperature reading from that date, with resolution data sourced directly from the National Weather Service's time-series database for station LLBG. The settlement window closes at 12:00 UTC on 1 June, though final resolution requires data confirmation from the following day.

Early June in the Tel Aviv region typically sees temperatures between 28–32°C, with occasional peaks above 33°C during heat waves. Historical patterns from the past decade show that June 1st temperatures at Ben Gurion average around 29–30°C, though extremes have ranged from 26°C in cooler years to 35°C during anomalous heat events. The current 0% implied probability on Polymarket's order book suggests traders are pricing in either a specific temperature threshold that appears unlikely based on seasonal norms, or minimal liquidity formation around this particular date and location combination. The probability distribution reflects typical early-summer Mediterranean conditions rather than exceptional weather scenarios.

Traders monitoring this market should track Mediterranean weather patterns and any anomalous heat systems developing in late May 2026. Regional meteorological forecasts typically become reliable 7–10 days before the settlement date. Sea surface temperatures in the eastern Mediterranean and upper-level atmospheric patterns will influence whether June 1st experiences typical seasonal conditions or a heat spike. Current order book positioning suggests limited trading activity, meaning early-season weather model consensus from established forecasters will likely anchor market expectations as the date approaches.

How this market resolves

Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.

How to trade this market step by step

The mechanics for trading "Highest temperature in Tel Aviv on June 1?" 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?

$32K 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 $6K 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.
