I rebuilt my Polymarket weather bot Launched a simulation... with $1,000 An hour later, it was already $1,250. Another hour later - $680 The problem was simple: the forecast changed, but the bot didn't know about it and continued to hold its position That's exactly what I'm fixing in version v2 What I'm adding: 1. Expected Value EV = (p · b) − (1 − p) Before every entry the bot calculates expected value. Negative EV - no trade. But EV is useless if p comes from nowhere 2. Kelly Criterion f* = (p · b − q) / b Determines exactly how much to bet based on real edge Small edge → small position. Large edge → larger. Fixed sizing can't do this 3. Brier Score BS = (1/n) · Σ(fₜ − oₜ)² Measures how accurate our probabilities actually are. If the bot assigned 80% but the outcome won 40% of the time - Brier Score catches that 4. Calibration on own data After each trade the bot saves city, month, bucket, forecast at entry, final result History accumulates → bot calculates Brier Score on its own trades → if Chicago in March is consistently off - p for that city and month gets adjusted automatically 5. Adding new data sources Instead of relying on a single source, the bot will draw on several sources at once, and if the forecasts match, it will enter into a trade Every cycle of v2: - scan markets - check station forecast - apply calibration - calculate EV - apply Kelly - enter or skip - monitor every minute - close if forecast changes Btw, here's a short video clip showing the terminal in action A major update is coming soonshow more

How to build your own weather trading bot Every... weather trader making money on Polymarket follows the same 7 steps. Free data. Simple formula. Repeat daily Traders making $20k-$180k all started here free APIs, basic math the crowd ignores, and patience Here's the playbook: Step 1: Pick 2-3 cities Don't try to trade everything. Start with NYC, Chicago, and one international city. Learn how the forecast behaves for those exact locations. Fewer cities = faster feedback loop Start copy-trading any trader even with $10 → Step 2: Pull free forecast data Open-Meteo API free, no API key, updates every 6 hours. NOAA official US government forecasts, 85-90% accurate at 1-2 days. Windy / Ventusky, visual model viewers to sanity-check your data These are the same data sources the top weather traders use. All free. All public Step 3: Turn forecasts into probabilities The market shows 8-12 temperature buckets (25°C, 26°C, 27°C). Your job: calculate the real probability for each bucket based on the forecast Simple method: > take the forecast daily max > assume ±1.5°C error range > simulate 50,000 scenarios > count how many land in each bucket > that's your probability per bucketshow more

I launched a weather trading bot on Polymarket with... $100 -> $8,000 here is how it works and how to copy it most people on polymarket price weather markets randomly based on vibes or a phone app but there is NOAA - a government agency that publishes free forecasts with 94%+ accuracy the result? you regularly see something like this: > NOAA gives a 94% probability that NYC will reach 74°F on Saturday > polymarket prices it at 11¢ the bot buys at 11¢ sells when the market corrects to 45¢ that is 4x on an almost guaranteed outcome how to launch it in 5 steps: > install OpenClaw on your pc > connect it to ChatGPT Plus + a telegram bot > create an agent on simmer markets deposit $100 > install the weather trading skill with: clawhub install simmer-weather > send the config to the bot and it starts trading the bot scans 6 cities every 2 minutes non-stop example of a real trader: profile: +$75,055 just from weather markets zero emotions. fully automated the window is still open but not forevershow more

avg $1,230/day on Polymarket. it comes from changes in... the weather forecast, which is free and open to everyone. the setup guide is in this post the market already prices the forecast itself pretty accurately. the money shows up the moment the forecast changes and the price hasn't yet. how it works in practice: when a new forecast for the next day comes out and the temperature in it moved by at least 0.5°C, you buy the option one degree closer to the new forecast. say the morning forecast promised 16.8°C in London, so the 17°C option is the priciest. in the afternoon a new forecast comes out with 15.8°C. your job is to buy 16°C while it's still cheap. the buy range where the EDGE holds: 5¢ to 60¢. the faster you do it, the higher your ROI how to set it up: 1 - get forecasts for free on Open-Meteo. it has the american GFS model and the european ECMWF. use the airport coordinates, that's where Polymarket measures the temperature. 2 - the bot should check on a timer whether a new forecast is out, and if it is, compare it to the previous one. 3 - if tomorrow's high moved by 0.5°C or more, the bot buys the option one degree closer to the new forecast. 4 - keep each trade under $25. cheap sellers on these markets are thin, and more size will eat the edge. one bot trades these forecast shifts across 50 cities every hour. in september that's avg $1,230/day here's the profile:show more

Found a trader who turned $8 into $56,000 trading... weather on Polymarket his strategy looks dumb until you see the math His profile: How he does it: -> only trades weather markets (temperature in London, Milan, Paris, Sao Paulo) -> waits until the day before resolution when the forecast is locked -> buys outcomes at 99c that resolve at $1 = +1c per trade -> 4,103 predictions, mostly micro-trades -> compounds tiny edges into 5 figures The part most people miss: his edge isn't predicting the weather -> it's noticing that on resolution day, the market still trades at 99c instead of $1 The math behind this is in the article below: the script from the article + free NASA data lets you run the same logic on any monthly weather, CPI or temperature market 👇 Copy him with me:show more

I’m making $2,200/weekly from Weather Arbitrage. I’m not posting... this as clickbait. If you can’t replicate it, feel free to unfollow me. About a month ago, I found a Polymarket Account using a clever strategy: Weather Arbitrage. It caught my attention. After digging into how it works, I saw that this trader focuses only on daily temperature markets for cities like NYC, LA, Atlanta, Denver, Chicago, Seoul, London, Shanghai, San Francisco, and Munich. The key insight is that each Polymarket weather market resolves based on a specific airport weather station, for example NYC = LaGuardia / KLGA, Dallas = Love Field / KDAL, while most retail traders rely on city center data. The temperature difference between those can be 3–8°F. According to his profile: > He built a bot that profits from this gap between official weather data and uninformed retail traders. I figured I wasn’t skilled enough to build something like that myself, so I set up a copy trading bot with 0% fees and 100 ms latency: > This copy trading bot is the best solution on the market, at least because it doesn’t charge any fees. Now I copy his trades exactly and made almost $10,000 in a month. It actually works, guys. Check it out. This isn’t clickbait or a joke.show more

+$8,500 IN 30 SECONDS. THIS FUCKING GENIUS BUILT HIS... OWN TRADING BOT WITH AI 🤯 He didn’t spend months learning how to code. He used an AI tutorial to build a bot that analyzes the market, finds setups, and executes trades based on his strategy. Now that tutorial is basically helping him automate his trading. Here’s how he did it ↓ → Picked one simple trading strategy → Used AI to turn the rules into a trading bot → Added entry + exit conditions → Backtested the strategy → Automated the execution → Let the bot scan for setups The key part: He didn’t ask AI to magically “make money.” He gave it a clear strategy and used AI to turn those rules into an automated system. One trade reportedly made him +$8,500 in around 30 seconds. Obviously, this doesn’t mean every trade will look like that. But the idea is powerful: You don’t necessarily need to become a programmer to start building your own trading tools. AI can help turn a trading idea into something you can actually test and automate. Here’s the full strategy + how he built the botshow more

Claude and a free weather API will earn you... $100k+. Success rate for beginners: 80%. Complete guide and algorithm for building Polymarket weather trading bot. Simple logic, a low entry budget and high ROI -that’s why weather bots are so clean. Onchain proof these bots exist: 1st bot: 2nd bot: I verified their profitability by myself copying every trade - each bot's win rate over time ranges from 80 to 90%. I grew my starting capital by +40% in just one week. You can copy their trades and see for yourself in two clicks through this bot: The alpha is simple: you're not trading weather. You're trading other people's ignorance. Gap between what the crowd prices and what 51 ensemble models say. Polymarket asks: "Will Atlanta hit 95°F tomorrow?" Normies bet on vibes. You bet on math. The core tool: Open-Meteo API. Free. No key needed. 51-model ensemble. Clean JSON. Cooked and ready. Update every 30 min. Hardcode your city coordinates - don't waste time on geocoding at runtime. This single endpoint beats most paid tools for what Polymarket actually needs. The edge in one sentence: Market is heavy on 16°C. Your 51-model ensemble points at 19°C. That's your trade. Find that gap systematically across every city market, every day - and you have a scanner. That's what separates consistent traders from gamblers. How to start: - Week 1: Open-Meteo + tropicaltidbits. Pick one city market. Track model vs market price daily. Don't trade yet — just watch where you'd have been right. - Weeks 2–3: Automate the pull. Log ensemble divergences. Build the scanner. - Week 4: Now you have an edge. Trade it. Most people want to skip to week 4. That's exactly why most people lose. Now you have the algorithm framework plus a complete guide to get started. All that's left is to actually do it.

$1,500 → $33,000 on 5min BTC markets in 2... days This is the new reality. It stops being gambling the moment you define an exact algorithm. Here are the recommendations on how to create the same trading bot: → Write your code in Rust – it offers C++ level speed, and there’s an official polymarket-client-sdk available. → Minimize Latency – your trading bot must be deployed in the same data center as Polymarket: AWS eu-west-2 (London). This ensures the lowest possible execution lag. → Price Discovery – Polymarket pulls prices from Chainlink, but Chainlink doesn’t "create" the price; it simply aggregates and broadcasts it. Use Binance – as the largest spot exchange, it is the primary source of price discovery. → Apply the Black-Scholes Model for binary options – this is exactly what will help you identify +EV opportunities by calculating all necessary Greeks and variables. → Don’t turn it into a casino – use the Kelly Criterion. It acts as your risk manager, calculating the optimal % of your bankroll for every single position. If you want to earn like trading bot devs – you need to think like them.show more
