Free Polymarket bots & tools
Everything in the catalog that you can start using without paying, sorted by what "free" actually means here — because an open-source bot you self-host, a free tier with a Pro plan behind it and a terminal that takes 1% of every trade are three different deals.
Completely free
44No price, no paid tier named, or open-source under a free licence. The author may still charge for something later — check the pricing note on each listing.
Up or Down BTC
Call Bitcoin up or down and find out in five minutes. A round is one public Binance BTCUSDT candle — its open is the price to beat, its close decides it — so there is nothing to install, no wallet to connect and no bot to keep alive: you tap a side and watch the chart. Prices move with the market while the round runs, so a side that falls behind gets cheap and pays multiples if the last minutes turn, and the exact payout sits on the button before you tap. Start on a 25 USDT welcome balance without even making an account, stake from 1 USDT, and top up later in about 200 coins.
Kalshi AI Trading Bot
Open-source Python toolkit for automated trading on Kalshi, built around the question most bot repos skip: do you actually beat the book? An LLM reads each candidate market with a news summary, scores a probability through any model on OpenRouter, and the trade is sized at quarter-Kelly under a risk governor with a daily-loss limit and a drawdown kill switch. Every decision goes into a local journal; the edge harness then pulls Kalshi's own settlements, scores your settled trades by Brier score, log-loss and realised win rate against the price you paid, and refuses to call it an edge on fewer than ten trades that resolved after you bought. A policy step turns that record into a pre-trade gate that blocks categories you have lost money in. Ships a paper mode, a Streamlit dashboard, a Claude skill and an MCP server; MIT-licensed at github.com/ryanfrigo/kalshi-ai-trading-bot.
Pulse Market
Web terminal for Polymarket's own markets and order books, built around the way in and the record after rather than any strategy: sign in with an email code or Google, fund a Polygon trading account with USDC or USDT from six networks from $10, and trade with no gas to pay. The Screener puts every tradable market into one table — price, 1h and 24h change, spread, 24h and all-time volume, depth, close time and match start — with range filters on each column, a topic filter and five presets: All markets, Undecided at 40–60¢, Top movers, Live now and Closing soon. The trade panel takes market orders and a beta limit mode with an expiry, shows the book and spread underneath and folds the fees into the total before you confirm. Analytics covers your own trades: realized and unrealized P&L by day, win rate, average stake, time in trade for wins and for losses, best and worst trade, and a Price vs. win block that sets your entry prices against how often you actually won. Pulse Points accrue per trade; rule-based automation, an AI assistant and API trading are marked coming soon. A verified Polymarket builder, paid through Polymarket's builder-fee registry at 0.5% per fill.
CloddsBot
Open-source AI trading agent that runs on your own machine and takes orders in natural language over Telegram, Discord, WebChat and eighteen other channels. Powered by Claude, it covers ten prediction markets — Polymarket, Kalshi, Betfair, Smarkets, Drift, Manifold, Metaculus, PredictIt, Opinion.xyz and Predict.fun — plus perpetual-futures exchanges and Solana and EVM DeFi. The Polymarket layer is real code rather than a wrapper: an EIP-712 order signer with unit tests, a CLOB client exposing 60-plus methods, real-time data and user WebSocket feeds, a large-trade tracker, and round-based discovery of the 5-minute BTC and the 15-minute, hourly, 4-hour and daily crypto windows with four automated strategies, alongside cross-venue arbitrage detection, copy trading and DCA bots. MIT-licensed at github.com/alsk1992/CloddsBot: 2,700 stars, 460-plus commits from one primary author, v1.9.1 released Sep 12, 2026, installed with one npm command on Node 22.
Kairos
Cross-venue trading terminal that merges Kalshi, Polymarket and Predict.fun into one order book. Matching contracts on different exchanges are shown as a single instrument with a composite ladder and a global best bid and offer, so you can see which venue is actually cheapest before you send, and an order to the NBBO endpoint routes to whichever book shows that price. Feeds are ingested next to the venues and merged in the browser with no polling interval; the ticket carries GTC, GTD, FOK, FAK and IOC time-in-force, post-only and slippage caps, with batch cancel and a per-venue kill switch. A bots panel runs parameterised templates — market making, cross-venue arbitrage, dip buying — against recorded books first and promotes the same config to live. The same engine is exposed as a REST and WebSocket API with scoped keys, IP whitelisting and a free read-only market-data tier. Built by a team from high-frequency trading firms and exchanges and backed by a $2.5M seed led by a16z.
Kreo
Telegram bots for Polymarket and Kalshi built around copy trading. Each copy task follows one wallet with its own buy mode — fixed amount, exact copy, a percentage of the leader's size or portfolio-weighted — under minimum and maximum buy, daily, total and per-market spend caps, category and price-range filters, slippage tolerance, stop-loss and take-profit, a monitoring mode that watches without buying, and a schedule; bulk settings edit dozens of tasks at once. Auto Trade runs rule-based entries on the crypto Up/Down windows and on sports, with presets, an auto-hedge that takes the other side when the pair is net-positive after fees, and up to 10x on selected markets. Around it: a wallet tracker, unusual-activity and new-market alerts, charts, parlays, and a backtest and portfolio lookup. Polymarket wallets are Gnosis Safes secured by Privy enclaves with the owner key exportable; deposits by crypto or card. Fees follow a bell curve per share, from 0.3¢ at the extremes to 1.75¢ at 50/50, with cashback tiers.
POLYDESK
Desktop click-trading cockpit for Polymarket from itereon GmbH in Vienna: a one-click price ladder and a grid view in the style of exchange trading tools, with stake presets, quick take and quick cancel, hotkeys, live depth minimaps, cash-out and exposure figures, position and P&L tracking and a session log. It runs on your own Windows or Apple Silicon machine and talks to Polymarket directly — the signer key is generated and stored locally and signs every order on-device, with no itereon server in the path. An ARMED / DISARMED toggle and a red CANCEL ALL sit in the top bar, and paper mode trades the full cockpit against live data with simulated fills. Free for life with live trading included under size caps — $25 stake, $100 exposure and five open orders per market — and no builder fee; a flat Plus licence will lift the caps. Open beta since September 2026, closed-source, shipped as checksummed GitHub releases.
PredictEngine
No-code bot builder that hosts and runs Polymarket strategies for you. You describe a rule in plain English — “buy BTC UP when it dips below $0.40” — or pick a template, and the platform writes the bot, provisions a dedicated Polygon wallet, signs the orders and keeps it running 24/7 on its own infrastructure, with a dashboard, a Discord bot and a mobile terminal to watch it. Templates cover single-side entries, cross-market arbitrage, copy trading that mirrors chosen wallets, market making and sports value against bookmaker lines; a marketplace lets users publish bots for others to run. The free plan runs five live bots; $9 a month unlocks the AI builder, 25 bots and backtesting; $49 adds an unlimited builder and 25% lower trading fees. The docs list Limitless and Predict.fun alongside Polymarket. The wallet is generated and encrypted on their side and the private key is exportable at any time.
Sonist
Mention-market trading software that listens to a live broadcast and buys the contract the moment a tracked word is said. Sonist pulls the mention markets from Kalshi and Polymarket onto one board — 53 approved events the day we checked it, 36 on Kalshi and 17 on Polymarket — each contract already carrying its keywords, its aliases and the count that settles it. Point a session at a stream URL, your microphone or your device audio and Sonist transcribes word by word; when a keyword clears its threshold it fires an immediate-or-cancel order on your own exchange account, under a contract cap and a maximum price in cents that you set before the session starts. The board re-marks over a websocket as the book moves, every detection and every skipped signal is logged with its reason, and one control flattens the position. Pro adds local speaker diarization, so a mention only counts when the voice that matters says it — the Fed governor rather than the anchor quoting him.
EventArb
Free cross-platform arbitrage calculator for event contracts. Punch in YES/NO prices for the same event on Polymarket, Kalshi or Robinhood and it does the math each venue's fee schedule implies — whether buying opposite sides locks in a profit, what the spread nets after fees, and the opportunity cost of parking capital until resolution. Supports binary and multiple-choice markets, side-by-side venue comparison, shareable links and free email notifications when opportunities open.
Kuest
Open-source white-label infrastructure for launching your own Polymarket-style exchange — the team calls it the Shopify for prediction markets. A guided no-code flow takes a branded site live in about 15 minutes on your own domain, with shared liquidity synced from live Polymarket order flow so the books aren't empty on day one, and a 0.5–3% per-trade fee you set yourself, paid straight to your wallet. Runs on Polygon with USDC settlement, ships Python and Rust SDKs compatible with existing Polymarket tooling, and the entire TypeScript stack is public on GitHub with 1,000+ stars.
Polymarket Markets Data
Community Dune dashboard that tables every Polymarket event, market and answer — USD volume by month and by day, active-wallet counts, and full drill-down tables — sourced from Polymarket's Gamma API through a materialized view refreshed daily. Dune's own blog featured it as the showcase for LiveFetch queries. Every underlying SQL query is public: fork it on Dune and build your own screens on top.
Virae AI
AI trading terminal for Polymarket, in private beta: market discovery with live trending topics and order-book prices, a whale leaderboard ranking tracked wallets by PnL, volume, win rate and Sharpe with one-click copy tasks, and seven trading Agents across four strategy types — end-of-round BTC/ETH price-distance, pre-market maker ladders, weather-model probabilities and Musk tweet counts. Agents watch every eligible round and only place orders when sizing, liquidity and entry rules all pass; each ships with recorded paper performance clearly labelled as simulation, and the strategy-evaluation core is open source on GitHub. Turnkey-backed non-custodial wallets, web app plus Telegram bots, and a separate Solana memecoin terminal.
Ratio
Social prediction-market app for iOS and Android built around copying Polymarket traders. Browse markets, follow forecasters from a global leaderboard, mirror their positions with your own sizing, and read the reasoning they post next to each trade. Wallet tracking, alerts and portfolio analytics sit alongside the feed. The wallet is self-custodial — you hold the keys and can export them — and every trade settles on Polymarket itself, not on Ratio's infrastructure.
Infinity
A full trading terminal inside Telegram, covering two venues at once: Polymarket prediction markets on the live CLOB order book, and Hyperliquid perps and spot — plus copy-trading on top. There is no baked-in strategy; Infinity is the execution layer, so you decide and it fills. Each account gets its own dedicated wallet per venue, AES-256-GCM encrypted at rest and exportable at any time. Written in Rust, translated into 8 languages, and running on mainnet with on-chain fills anyone can verify.
Almanac
Prediction market that pays for being right early. Almanac routes yield to traders who commit to positions well before resolution — time-weighted scoring gives higher multipliers the earlier the call, consistency premiums reward accuracy held across horizons. Covers macro, policy, regulatory and election outcomes, with an institutional signal API on the way.
Poly Helper
Browser extension that upgrades Polymarket without leaving its interface — 25+ context panels: live crypto and stock stats, sports intel with live scores, bookmaker odds comparison across 19 sportsbooks with automatic edge detection, polls vs market price on election events, top-holders PnL, a tracker to follow top traders, breaking-news X feed, LP-rewards calculator and TradingView-style charts.

Installs into Claude Code, Cowork, Codex and other agents.

No subscription — a fee per trade
13Nothing up front; the tool takes a cut of each trade or of profits. Free to try, not free at volume.
Miramarket
No-code builder for conditional Polymarket strategies: lay out markets, conditions and actions on a canvas or describe them in plain English, simulate, then Run Live. Conditions watch a price, ROI or P&L threshold, a time before close or a date, or how a market resolves; actions buy a YES or NO side, hold, or send their share back to the wallet, with allocations that must add up to 100%. Eleven templates cover take-profit and entry ladders, bracket and reversal exits, barbells that pair a conviction leg with a protective one, and bolt-ons that trade one market off a catalyst or a move in another; a recurring filter keeps an action pointed at the live window of a repeating market series. The AI assistant drafts, explains and edits the tree, and a CLI on npm posts the same strategies as JSON from a terminal or an AI coding agent. Accounts run on Privy wallets you delegate to Miramarket, so a live run can sign while you are away.
Olympus
Polymarket web terminal built around copy trading that keeps running on Olympus's servers after you close the tab. Every followed wallet gets its own ratio, trade and market caps, odds, liquidity and volume filters, a price-deviation guard and a limit mode that buys at the leader's own fill price, with stop-loss, take-profit, counter-trading and combo copying; a backtest replays the leader's history through those exact settings first, and separate trading wallets keep strategies apart. Around the copier: a manual terminal with a sports hub, crypto price windows, combos and TP/SL on any position; Bonds, which ranks every outcome priced 97¢ or more by what it pays after fees, and Autobond, which buys them inside a budget and a loss limit; an LP Rewards desk that places maker orders on Polymarket's reward markets; Polymarket Perps to 20x and Dimes Multiply positions to 10x; and a REST trading API with wallet-scoped keys. The base fee is 0.75% per executed trade, sliding toward zero at extreme prices. Built by the team behind SOL Decoder and Valhalla.
PolyCop
Telegram copy-trading bot with a public smart-money radar behind it. In the bot, Copy Trade mirrors any target wallet's buys and sells under your sizing, price and amount filters, with a sub-wallet per target if you want each leader trading from isolated funds; Sniper Mode rests limit orders at your price; AFK Auto Trade scans markets every five minutes and fires when your trigger conditions line up, with templates to start from; an AI wallet check grades any address you paste. PolyCop.fun, the web side, ranks wallets by copyable P&L, win rate, slippage and recent-20 record, and its Copy Backtest replays a wallet's history against your capital, copy percentage, slippage and filters, with a time-machine view of the equity curve. Fees are a flat 0.5% per transaction with gas covered, including auto-redeem of settled markets. Polymarket's own builders Data API puts PolyCop at $360M attributed all-time across 12,661 users, $19.4M in August and $6.0M in the first half of September, rank 12 for the month when we checked.
PolyGun
Telegram bot for trading Polymarket without a browser: browse markets, buy and sell instantly, set limit orders, copy wallets and track the portfolio from one chat. On /start the bot generates a Polygon wallet for you, and deposits auto-bridge from Polygon, Solana, Ethereum and BNB. Copy trading follows any wallet and mirrors its entries and exits under your own settings, a Smart Wallets tab lists the most-copied addresses, and shareable P&L cards are built in. PolyGun charges a flat 1% on every buy and sell, sponsors gas, and pays referrers a share of fees. It sits on one of the larger Telegram communities in the space — the Prediction Desk group behind it had 25,635 members when we checked — and Polymarket's own builders Data API attributes $117.6M to it all-time across 9,905 users, though the monthly run rate has fallen from $18.3M in April to $2.6M in August and $0.8M in the first half of September.
PolyWin
Telegram bot that puts the whole Polymarket workflow in one chat: copy trading, two snipers, backtests and AI trader discovery. Copy Trade mirrors — or counter-trades — any wallet you pick, sized as a fixed USD amount, a percentage of the leader’s stake, or portfolio-weighted so your allocation matches theirs with a 0.01–10× multiplier, under category, price-range, market-volume and daily-spend limits with take-profit and stop-loss on every copied fill. Final Snipe fires a market order the second your entry conditions pass; Reversal Snipe ladders limit orders into an overreaction and cancels unfilled rungs about five seconds before resolution — both across BTC, ETH, SOL, XRP, BNB, DOGE and HYPE on 5m, 15m, 1h and 4h. Every snipe strategy can be backtested against a pre-computed pool of parameter combinations first, returning Most Profitable, Fast and Safest variants. AI Picks re-scores Polymarket traders every six hours, discarding wallets that show wash trading or leaderboard farming. Non-custodial: a Polygon wallet is deployed on first start, keys are encrypted per wallet and exportable, and TOTP 2FA gates withdrawals and key exports. No KYC, and deposits from ten chains auto-bridge to USDC.
PredMart
Margin account for prediction markets. Open a position on any of 10,000+ markets with up to 5x leverage, or post prediction-market shares you already hold as collateral and borrow up to 80% of their value in USDC without selling them. USDC lenders supply the other side and earn the borrow interest. Non-custodial smart contracts on Base, audited by Hashlock, with no KYC and no account creation — you connect a wallet and trade. Still labelled beta.
Betly
Mobile-first social prediction-market app. Bets show up as posts you can react to, reply to and re-bet in one tap; discover trending and breaking markets, build a profile and climb leaderboards. Routes orders through Polymarket and settles on Polygon, with fee discounts for BETLY token holders.
Betmoar
Web trading terminal and Discord bot on top of Polymarket, and the largest third-party interface by Polymarket's own count: rank 1 on the Builders leaderboard, with $2.2B attributed since the program began in October 2025, $137M in August and $63.7M in the first half of September. It is not an exchange — you connect the wallet you already trade with, orders go into Polymarket's book carrying Betmoar's builder code and settle on Polygon — but the screen shows what polymarket.com does not: top holders and position delta per market, profit analysis that separates winners from wash traders, a real-time news terminal sourced from X and Truth Social with text-to-speech alerts, a live UMA dispute dashboard with vote reveals and large unrevealed voters, a resolution calendar, and a bookmaker-style sports grid with moneyline, spread and total prices in cents or decimal odds. The Discord bot puts the same trading and market cards inside community servers; Betmoar says it powers Polymarket's official server and 100-plus others. It adds no builder fee, so trading through it costs what the native site costs.
Overdog
Telegram bot that shows smart-money positioning on every Polymarket event — which side the profitable wallets are on and how much capital backs each outcome — then lets you trade from the same screen. Browse sports and politics, set limits and stop-losses, or copy top traders automatically.
PolyBot
Telegram trading bot for Polymarket. Copy top wallets automatically, or build custom strategies with trigger prices, take-profit, stop-loss and trailing stops — orders route through your own non-custodial Safe wallet at a flat 1% fee.
Polycool

Precedence
AI trading terminal for Polymarket. Estimates true probabilities, detects mispricing and shows where the edge is across thousands of markets — with gasless Smart Wallet execution on Polymarket's order book and UMA-verified settlement.
Stand
Advanced trading terminal and aggregator for prediction markets. Pulls Polymarket and Kalshi into one trade-first interface with live volume, liquidity and open interest, whale copy-trading, TP/SL and stop orders, and an Octobox that watches up to eight markets at once. Non-custodial via Privy, no fees on manual orders.
What "free" means on Polymarket
Free comes in three shapes here, and the groups above keep them apart. Fully free tools — open-source bots you run yourself and web apps that don't charge — come first. Then the freemium tier: a usable free plan with the features that matter behind a subscription. Last, tools that cost nothing up front but take a percentage of every trade or of profits; those are free to try and anything but free once you trade size.
Most free entries are analytics, screeners and copy-trading terminals rather than automated bots: the hosting is the product and the business model is the paid tier or the per-trade fee. Fully automated bots that are free tend to be open-source repositories — which means you supply the server, the API keys and the operations, and nobody is on call when it breaks.
Listings whose pricing isn't published ("see site", "waitlist", "custom") are deliberately not counted as free. We only file a tool under free when the author says so.
How to pick a free tool
Ask what the free plan actually does. Many free tiers show data but gate execution, alerts or the strategies you came for. Check the feature list on each card against what you would actually use, then read the pricing note on the detail page for the catch.
Per-trade fees add up faster than a subscription. A 1% fee on every fill is $10 per $1,000 traded each way; trade actively and a flat monthly plan can be the cheaper "free" option. Work out your monthly volume before you call anything free.
Free still costs you your keys. Only connect wallets and API keys to tools you have checked, prefer non-custodial setups, and with open-source bots read the code before you fund it — the point of having the source is that you can.
Frequently asked questions
- Are there completely free Polymarket bots?
- Yes — the open-source ones. They are published under free licences (MIT) and cost nothing to use, but they are free software rather than a free service: you host them, you supply the API keys, and you operate them. The "Completely free" group above lists them alongside free web tools.
- Is a free tier enough to actually trade?
- Sometimes. Free tiers on terminals and trackers usually cover research — screening, wallet tracking, alerts — and gate execution, automation or the higher-value signals. Read the pricing note on each listing; it says what the free plan leaves out.
- What is the difference between free and open-source?
- A free tool costs nothing to use; an open-source bot also lets you read and change the code, and keep running it if the author disappears. Every open-source bot here is free, but most free tools are not open-source. They have their own page: open-source Polymarket bots.
- Do free bots publish performance?
- Rarely. Most free tools are research products without a trading record to publish, and most free bots are open-source repositories that ship no live results. Every listing shows the author's published 30-day ROI or N/A; POLBOTS does not verify performance either way.
- Why isn't a tool I know is free on this page?
- Because its listing doesn't say so. Tools that publish no pricing ("see site", "waitlist") are not filed as free, and tools with a per-trade fee are in their own group. If a listing is out of date, tell us and it gets fixed.
