Kalshi traders have public records and a bot can copy them
Kalshi is unusual among prediction markets in that many traders are visible by name. Rivo tracks those traders continuously, records every trade we see them make, and scores each position when the market settles. A trader's profile shows a real profit curve, a win rate measured against the odds they paid, results by bet size and by category, the markets they trade most, and a simulator that replays copying them at $25, $100 or $250 a trade over the last 7, 30 or 90 days.
That record is what a copy bot is built from. Open a trader on the Kalshi whale tracker or the ranked traders, read the record, and hand them into the builder. The bot then trades every time that trader opens a position, in the market they chose, on the side they chose, at the size you set. Two or more traders can share one bot.
Or build a signal from incoming Kalshi trades
Kalshi prints a steady stream of large trades across sports, politics, economics and weather, and a signal picks out the ones you want: a category or league, a minimum size, a keyword in the market title, a specific market, an entry price band, and whether the trade opened a position, added to one or flipped sides. A signal does not care who placed the trade. Four templates, from sports whales to longshots, give you a working signal in one click, and every field is editable before you save.
The bot proves itself before it spends
The second screen replays the trader or the signal at your size on Kalshi markets that already settled. For a signal it splits the last 90 days into an older training window and a recent validation window and flags a signal that only worked in the past. Then the bot runs on paper, recording every trade it would have made with virtual money and scoring it on settlement. When the record earns it, you promote the bot to live from its own page. One Kalshi detail: the entry price band in a signal is the YES price, so a trader buying NO paid the complement, and the backtest scores the trade at the price they actually paid.
Live through your own Kalshi key
A live Kalshi bot is non-custodial. You connect your own Kalshi API key, it is encrypted at rest, and every order the bot places is placed by your key on your account. There is no Rivo balance to top up, no pooled wallet, and no path by which Rivo can move your money out. Disconnecting the key in settings wipes it and stops execution immediately.
- Entries only. The bot opens positions. Closing stays your decision, or a stop-loss and take-profit rule you arm per position.
- Two ceilings, both yours. A maximum per trade and a maximum per day. The bot stops at both, and presets start small.
- It sizes to the book. A Kalshi bot sizes down to the depth available inside your slippage boundary rather than pushing an order through a thin book.
- It skips rather than chases. A trade past the copy window or a price that has already decided the outcome is skipped and logged with the reason.
- It stops itself. Three consecutive execution failures pause the bot. A thin book does not count.
What a Rivo bot is not
It is not an arbitrage bot. Rivo does not run cross-venue arbitrage between Kalshi and Polymarket, market making, or latency strategies against the order book. It is not a plain-English strategy generator either: a Rivo signal matches what incoming trades can actually answer, which is what keeps every backtest honest. If you want an arbitrage bot, a market-making bot or a hosted Python runner, the Kalshi trading tools comparison names a few.
