Automations that keep watch.
Each one waits for its own setup, trades by its own rules and keeps its own record. Switch on the ones you want.
Bitcoin
Trades Bitcoin's 15-minute Up or Down markets around the clock. It watches Polymarket against Kalshi's identical contract and the live index, buys when they disagree, and holds to settlement.
- Every 15-minute window, day and night
- Priced against Kalshi and the live index
- Its own size and loss limits
Sweeper
Buys the team that has all but won, late in the game, once the score and the market agree. Then it holds to settlement.
- NBA, NHL and MLB
- Late in the game, with the score backing the price
- Its own entry size and a cap on what's open at once
Prop maker
Makes markets in NBA player props before tip-off. It quotes both sides around a fair price taken from the sportsbooks, moves with their lines, and steps away before the game starts.
- Points, rebounds, assists and threes
- Fair value from sportsbook lines, margin removed
- Maker orders only, so no fees
Weather
Makes markets in each city's high temperature for the day. Kalshi lists the same buckets, so Polly quotes around Kalshi's price and moves when it moves.
- New York, Chicago, Miami, Los Angeles and San Francisco
- Quotes that follow Kalshi as the forecast changes
- Maker orders only, so no fees
Scanner
Watches for positions that can't lose but are still for sale, and records how big they are and how long they last. It places nothing.
- NBA, NHL, MLB and NFL
- Games in play and just after the final
- Every find on record, with its size and how long it lasted
Paper trading
Every automation starts on paper against live prices and keeps its record either way, so you see how it does before a dollar is at risk.
Two switches for real money
The desk in live mode, and the automation armed. Saving its settings never arms it.
Limits that end the day
Each automation stops at its own daily loss limit. A limit they share turns the kill switch on.
Your orders still go through
The kill switch stops every automation and cancels their orders. The ones you place yourself are never blocked.
See the edge before you trade.
Pro-level pricing on every game. Polly lines up Polymarket's price beside Kalshi's and the sportsbooks' for the same outcome, takes out their margin, and shows your edge after Polymarket's fee.
- Kalshi's live price beside Polymarket's, so you see who moves first
- FanDuel, Pinnacle, DraftKings and BetRivers, margin removed
- The edge after the fee on the desk and on the ticket
Know the game before you bet.
Every team the exchange lists, on one page: the next game priced against the books, the last meetings, injuries, headlines, rest and weather, and your own record betting on them and against them.
Read the room.
Every game's chat, beside the price, with what each poster holds. Filter to the holders or the whales, sort by the biggest positions, and press Summarize to have Claude tell you which way the talk and the money lean, and what's changed.
- Names in the color of the side they hold, with the size of it
- Whales from $1,000, sorted by the biggest positions
- Summaries only when you press, on your own Anthropic key
The numbers Polymarket doesn't show you.
Polly reads your whole exchange history, trades you placed by hand included, and keeps real books: realized P&L after commission, a curve for each automation, and which sports actually pay.
Every fill, in Telegram.
Fills, wins and losses arrive as they happen, with the cost, fees and payout. A recap lands every night. Ask how the week went in plain words, or stop everything with one press.
- Stop is one press. Arming and resuming take two.
- Switch an automation on or off, or change its settings, from the chat
- Questions answered from your own data, on your Anthropic key with a monthly cap
Every day, on a calendar.
Settled P&L by day, split between you and each automation. Set a monthly goal and Polly paces it against your normal swings, so one bad day reads as one bad day.
- Each automation's record, live and on paper
- Win rate, edge against the price paid, profit factor and drawdown
- Realized edge, calibration and fill quality before you arm anything
Trade toward something.
Name what you're trading for, the rent, a trip, a new console, and Polly funds each goal in order from your settled P&L. Drag one up to make it next. Your streak counts the green days.
- A list of goals in your order, or one number for the month
- Funded from settled P&L, counted from the day you pick
- Your streak, your best run and your pace on Home
The rest of the desk.
Flip a position
Sell a side that's turning and back the other in one press. Pick where you want to end if it wins, cash out or even, and Polly sizes both orders.
Every sport
25 sports and 388 leagues, from the NFL and the Premier League to tennis, UFC, cricket and esports. New leagues are followed as they list.
Your whole portfolio
Every position you hold, placed in the app or on the desk, with its value and P&L as prices move and your resting orders beside it.
On your phone
Installs as an app, with its own iPhone layout for the desk, the ticket and your portfolio.
The rules, game by game
The exchange's own settlement text for every game, with what happens on a tie, a void or a postponement.
Ready for tax time
Every deposit, fill and settlement with the fee on each, a CSV of any range, and a tax report with Form 8949 for your accountant.
Your server. Your keys.
Polly is software you host yourself, on a small cloud server or a computer of your own. It trades through your accounts with your own API keys, and nothing passes through us.
Your own server
One small server runs the desk, the automations and your records, around the clock. Open it from your laptop or your phone.
- Your keys and your history stay on it
- The automations keep watch while you're away
- Never holds your money or trades for anyone else
Polymarket US

- Orders from the desk, the ticket and every automation
- Fills, positions and balance as they change

- Weather: Kalshi's price for the same temperature bucket
- Read only. Polly never trades on Kalshi
