Trade: Highest temperature in Munich on May 5?

Market context

On 5 May 2026, the highest temperature recorded at Munich Airport Station will determine which temperature range resolves as correct. The settlement window closes at 12:00 UTC that day, with resolution sourced from Weather Underground's historical data for the airport station. Current order book activity on Polymarket shows 0% implied probability across all temperature bands, indicating either minimal trading volume or a technical state where no positions have yet formed consensus pricing.

Munich's May weather typically ranges between 15–22°C for daily highs, though late spring can produce warmer conditions as continental air masses move northward across Bavaria. Historical May 5th temperatures at the airport station show variability; the city experiences transition weather between spring and early summer, with occasional warm spells driven by high-pressure systems moving from the south. Comparable years suggest most outcomes cluster in the 18–24°C range, though extremes in either direction remain possible depending on synoptic patterns.

Traders should monitor European weather forecasting updates in late April and early May, particularly from the German Meteorological Institute (Deutscher Wetterdienst), which publishes extended forecasts 10–14 days ahead. High-pressure ridges building over Central Europe or Atlantic low-pressure systems tracking eastward will be the primary catalysts affecting May 5th conditions. The current zero probability across all bands suggests the market awaits initial price discovery; early traders establishing positions will effectively anchor subsequent order book depth and implied probabilities.

Resolution source

This market settles from the official outcome published at https://www.wunderground.com/history/daily/de/munich/EDDM. 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 Munich on May 5?" 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?

$43K 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.

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.
