Weather markets have quietly become one of the most consistent and data-driven niches on Polymarket.
While most traders chase politics and crypto, a group of sharp players are quietly making serious money on daily highest temperature markets for cities around the world. These markets resolve frequently, are based on verifiable real-world data, and often contain pricing inefficiencies.
Here’s a breakdown of the Top 7 most profitable weather traders on Polymarket, ranked by PnL, consistency, and strategy:
1. ColdMath (The Champion – Bot-Driven Edge)
PnL: +$124,896 | Win Rate: 81.7% | Biggest Win: $12,400
ColdMath runs a sophisticated automated trading bot built on Clawdbot (Claude-powered AI agent framework). The bot constantly scans real-time weather data from multiple sources, compares it against market prices 24/7, and executes trades with precision.
Key strength: It buys Yes/No shares at extremely low prices (often 0.01¢–0.02¢) when it detects even tiny mispricings. This turns small entries into massive ROI.
This is currently the cleanest example of systematic, AI-powered weather trading on the platform.
2. VibeTrader
PnL: +$132,854 | Win Rate: 37.7% | Biggest Win: $21.3K
Highly versatile trader who dominates city-specific temperature markets (especially New York and Miami) while also crushing high-volatility side bets (like Elon Musk tweet counts).
Strong combination of weather analysis and opportunistic trading.
3. BeefSlayer (The Sniper)
PnL: +$62,064 | Win Rate: 68.2% | Biggest Win: $4,103
Specializes in buying extremely cheap, mispriced outcomes — sometimes for just a few dollars — and turning them into massive percentage gains.
Excellent at spotting when the crowd has over- or under-reacted to forecasts.
4. HenryTheAtmoPhD (The Professor)
PnL: +$55,838 | Win Rate: 36.5% | Biggest Win: $4,944
A retired professor of atmospheric science who brings real meteorological expertise to the markets.
Uses deep knowledge of atmospheric patterns and historical data instead of just short-term forecasts. A great example of domain expertise beating retail intuition.
5. HondaCivic (The Precision Buyer)
PnL: +$55,408 | Win Rate: 84.2% | Biggest Win: $15,000
One of the best at entering positions at incredibly low prices. He has turned tiny investments into enormous percentage returns by buying when the market significantly underprices certain temperature outcomes.
Highest win rate in the top tier.
6. russell110320 (The Global Macro Player)
PnL: +$43,936 | Win Rate: 64.3% | Biggest Win: $10,300
Focuses on broader global temperature and climate record markets (monthly anomalies, “hottest on record,” etc.) rather than just city-level daily highs.
Takes larger, high-conviction bets based on long-term climate data.
7. Maskache2
PnL: +$34,106 | Win Rate: 33.5% | Biggest Win: $7,639
Specializes in specific cities (Seoul, Hong Kong, Wellington, New York). Relies on historical data + forecast analysis to find mispriced thresholds.
Lower win rate but excellent at scaling into high-conviction setups and delivering big individual wins.

Weather markets on Polymarket are still relatively under-the-radar compared to politics and crypto, but they’re becoming one of the cleanest niches for systematic and expert traders.
Would you rather trade weather markets manually with deep analysis, or build/run a bot like ColdMath?
