What PolyMM does
Open-source Python bot for Polymarket's sports and esports markets, released by the person who ran it. It strips the margin from sportsbook odds to get a fair price, posts limit orders a cent above the best bid where the gap is large enough, and when one side fills, tries to buy the other outcome so both sides cost under $1. The code is free under the MIT licence, and its author says it is a foundation to build on, not a plug-and-play earner: the private odds scrapers are left out and it needs your own wallet, a paid the-odds-api key and a Supabase project.
Features- De-vigs bookmaker odds into a fair probability for each side
- Quotes a cent above the best bid when the edge clears a minimum, 7% in the pre-match config
- Hedges a fill by placing the opposite outcome, to hold both sides for under $1 a share
- Fill and order-book websockets, with an edge-lost event that cancels resting orders when fair value moves
- Starts at 10 shares per order
- Most bot repos come with a promise. This one comes with a public wallet and an autopsy. The author's write-ups put the January to April 2026 run at about $5k net: +$8,293 on completed arbitrages and -$3,184 on the forced directional bets left when a hedge did not fill. We checked the wallet @b00k13 against Polymarket's data: position P&L stood at $4,960 on May 1, 2026, matching the $4,960.77 on the author's profile screenshot. The total was $5,904 on Nov 5, 2026, but the author says the bot running now is a Rust rewrite, which is not in this repo.
- The candid part is why it faded. Those directional bets each carried at least a 7% edge on paper and still lost, and the author traces that to adverse selection: odds up to 30 minutes old meant the edge was often gone by the time a quote filled. In the author's words the bot “got too slow” to defend its edge, and running it unchanged means donating to quicker bots. The scrapers that the author calls half the edge are not included, so what you get is the stale-odds version of the problem, unless you bring faster data.
- Treat the code as a study piece. The author says it was built almost entirely with AI in spare time and that bugs are likely. It ships with a test suite, but the history is three commits, the last from Aug 16, 2026, so it is a one-off release rather than a maintained project; the repo has 117 stars and 39 forks. The README gives a 5% default minimum edge, while the config sets 7% before a match, 8% for live play and 5¢ only for a separate weather-market spread bot.
What PolyTraderBot does
Six self-hosted Polymarket bots from one developer, sold separately at $10 a month each and delivered as full source with a browser dashboard, tests and a Docker setup for your own PC or VPS. CopyBot follows wallets you choose, or candidates it ranks from Polymarket's public leaderboard, with fixed, proportional or Kelly-fraction sizing, ten-plus individually switchable guards and exits that follow the leader out. Crypto5min and Crypto15min trade the 5- and 15-minute up/down windows on BTC, ETH, SOL, XRP, DOGE, BNB and HYPE from tree-based models retrained every 60 or 90 minutes. ARB scans the order books for binary YES and NO asks that sum to less than $1 after fees. WeatherBot prices temperature buckets from a weighted blend of Open-Meteo models, NWS, NOAA and Met.no forecasts and compares the result with the live asks. PolyLiq rests two-sided quotes in the markets that pay Polymarket's liquidity rewards, or takes over the resting orders you placed yourself. Every bot starts with real orders switched off, keeps the wallet key in a local env file and, from the current releases, updates itself from its own dashboard. The vendor advertises no returns; a free Polymarket terminal from the same developer is in beta on the same domain.
Features- CopyBot — follow wallets you add or candidates ranked from Polymarket's public leaderboard by past results, settled history, activity and copyability; fixed, proportional or Kelly-fraction sizing; separate toggles for price-drift, spread, volume, extreme-price, duplicate-market and wash-trade guards; leader-exit detection with a 5-minute minimum hold
- Crypto5min and Crypto15min — seven assets each; tree-based models retrained every 60 and 90 minutes; maker-first, taker-only or maker-only orders; fixed, percent or fractional-Kelly sizing; confidence threshold, daily-loss limit and losing-streak pause; paper, dry-run and live modes switched from the dashboard
- ARB — WebSocket scan of up to 4,000 token books for YES + NO asks under $1; a minimum net profit after taker fees; fill-or-kill entries with retry-and-shrink and a fill-and-kill fallback; millisecond limits on book age and leg skew; daily loss limit and position caps
- WeatherBot — Open-Meteo global and regional models, NWS and NBM, NOAA TAF and METAR, HRRRCast and Met.no, each with its own weight; settlement station read from the market's rules; source disagreement lowers confidence; bias calibration applied only when it beats the raw blend on a recent holdout; best-bucket, adjacent-bucket ladder and low-probability NO approaches
- PolyLiq — Automatic Mode ranks reward markets by the share of the daily pool its own score would win and quotes both sides of YES inside the incentive band; Manual Mode takes over GTC orders you placed, rechecks prices every 30 seconds and restores unfilled size; inventory cap; Polymarket's published scoring formula
- Six products, not one suite: each bot is its own subscription, its own download and its own dashboard. What $10 buys is a Source Access licence — read the code and modify it privately, run it on two machines, no redistribution — tied to a licence key in a local file. The bot checks that key against PolyTraderBot's entitlement service, sending the product, the key, its version and a one-way hash of a machine fingerprint, and runs on signed leases with a limited offline window. When a subscription lapses the bot stops opening new or larger positions but, by the licence's own wording, can still cancel orders, close or reduce positions, redeem settled markets and withdraw, and the vendor undertakes not to delete your files remotely.
- “Paper mode by default” holds for five of the six. Crypto5min, Crypto15min, WeatherBot and PolyLiq start in paper mode and ARB in the dry-run it uses for paper trading; CopyBot starts with live buying switched off and paper trading as a separate toggle, and in that state it may still cash out winners and redeem resolved positions already in the wallet. The wallet key sits in an env file on your machine, and the privacy policy says the bots send no keys, trades or telemetry to the vendor — a statement we could not test without the source. Two cautions come from the vendor's own guides. The dashboard updater needs the Docker socket mounted, so anyone who reaches a dashboard can control Docker on that machine: WeatherBot and PolyLiq bind to localhost by default, while CopyBot and ARB listen on every interface unless told otherwise. And the AI Setup Assistant guide suggests pointing a coding assistant at the bot folder to read the env file — with a cloud assistant that passes the wallet key to the assistant's provider, whatever the prompt says about redacting it; the same guide's local-model route avoids that.
- Where the landing pages and the guides disagree, the guides are the more careful document. The ARB page sells complement and negative-risk baskets, while its guide says customer releases ship with negative-risk execution locked off behind an explicit experimental acknowledgement, leaving binary complement arb as the live default. The Crypto5min page leads with a CNN-LSTM network; the guide says the default is a lighter LightGBM and CatBoost stack and calls the CNN-LSTM an older backend kept for testing. The Crypto15min page's comparison table marks its delta-first mode as the default, while that page's own FAQ and the guide both have it off. The late-window entry mode the same page labels “Higher hit-rate” is, in the guides, off by default and assumes no fixed win rate, and the delta-first variant built on it “is not treated as validated until your own settled results show positive net performance”.
