Rainmaker is an autonomous signal engine that scans Polymarket weather markets every cycle. It pulls live forecasts from NWS and OpenMeteo, runs a multi-model consensus algorithm, compares predicted probability against current market odds, and fires a prediction to Telegram whenever it detects a statistically significant edge.
Hit the ▶ JOIN GROUP button anywhere on this page. You'll be directed to our Telegram Bot. Once inside, select your subscription model and follow through. Signals include the city, direction (YES or NO), edge score, Kelly fraction, and the direct Polymarket link.
Each signal includes a Kelly % — a mathematically optimal fraction of bankroll to risk, derived from the edge and probability of the signal. For example, Kelly 12% means risking 12% of the trading bankroll. We recommend using half-Kelly or less when starting out to manage variance.
A Rainmaker signal contains:
CITY · DATE — the market location and resolution date SIGNAL: [YES/NO] — which side has the statistical edge Edge +X.XXX — probability vs market odds (higher = stronger) Kelly X% — recommended bankroll fraction Conv X% · HIGH/MED — model consensus confidence level NWS+OM: agree/disagree — whether both forecast sources align
Rainmaker only fires a signal when the math clears all hard filters: minimum 4% edge, minimum 80% model consensus, valid spread ratio, and entry price within acceptable range. On average you can expect 1–5 signals per day. No edge, no signal.
Every signal posted in the group has a Polymarket link attached. Once the market resolves, the outcome is public and on-chain — there is no way to fake it. The 81% win rate is calculated from all signals broadcast since launch, including misses.
Yes, absolutely. An 81% win rate means roughly 1 in 5 signals loses. Weather is inherently uncertain — even the best model can be wrong. Never allocate more than you can afford to lose. Rainmaker is a tool for statistically-informed trading, not a guarantee of profit. This is not financial advice. Always DYOR.
To use Rainmaker's Telegram group: zero technical knowledge needed. Just Telegram. To trade on Polymarket you'll need a wallet — but Polymarket supports email login and card deposits via their embedded wallet. The learning curve is a 10-minute setup, not a computer science degree.
RainmakerBot is Phase 02 — a private automated trading bot that executes positions on Polymarket autonomously, with your custom risk parameters. Projected for Q4 2026. Signal group members get whitelist priority access.
