What is a Kalshi trading bot?

A Kalshi trading bot takes the trade for you the moment your setup appears. When a winning trader opens a position or a large trade fits the signal you built, the bot buys the same side on your own Kalshi account within seconds. It watches every Kalshi market around the clock, so the trade you were waiting for never happens while you are asleep.

You build it without code and prove it before it spends a dollar. Rivo has every Kalshi trade on its tape, so you replay your idea on markets that already settled, run it on paper against live trades, then switch it live inside a per-trade and daily limit you set. Your money stays in your Kalshi account the whole time.

The Kalshi trader to build a bot on in each market

The most profitable named trader with an A or B copy grade in each of Kalshi's busiest markets over the last 30 days. Point a bot at one of them, narrowed to the market they win in.

Rebuilt every hour from Rivo's record of every named Kalshi trader. The copy grade rewards a long record of wins, not one lucky month: methodology.

Copy bot: trade alongside Kalshi's winners

The copy bot puts a winning Kalshi trader's next move on your account. Pick a trader from the table above or from any profile, and every time they open a position the bot takes the same side of the same contract within seconds, at your size. You never have to be watching when they bet.

It is the fastest way to put a proven record to work. Every named Kalshi trader is scored bet by bet as their markets settle, so you back what someone actually did, and you can replay copying them at $25, $100 or $250 a bet before the bot spends anything.

What you set

  • Who it copies. One trader, or several traders in one bot.
  • How much. A fixed stake on every trade, or a share of the trader's own size with a dollar cap.
  • When it gets out. Sell when the trader sells, or your own stop-loss and take-profit on each position.
  • How much it can spend. A maximum per trade and a maximum per day. The bot stops at both.

Signal bot: act on the big money as it lands

A signal bot follows a kind of trade instead of a person. Describe the trades you want, such as large NFL buys between 30 and 70 cents or serious size on a longshot, and the bot acts on every one that prints on Kalshi, whoever placed it. It reads the whole Kalshi tape at once, every market, every minute, which no person can.

Four templates get you a working signal in one click: Sports Whales for big money on NFL, NBA, MLB and NHL games, Longshot Hunters for serious size on outcomes the market has written off, Politics Desk for elections and policy, and Big Money for only the trades that move a market. Every field stays editable.

What you set

  • Where it looks. A category, a league or specific markets, narrowed further by keywords in the market title.
  • What counts. A minimum trade size, and new positions, adds or flips.
  • What price. An entry range, such as 20 to 60 cents for value or under 20 cents for longshots.
  • What it does. Alert you, trade on paper, or place real orders on your own Kalshi account.

Market bot: trade the price on autopilot

A market bot runs your price rule on one Kalshi market, all day. Tell it to buy when Yes drops to a level or falls a set number of points, and to sell a set number of points above or below your entry. It never gets tired, never hesitates and never chases.

It shines on Kalshi's 15 minute crypto markets. Point it at the Bitcoin series and it moves to the next market every time one settles, running the same rule round after round. Market bots trade on paper and message you in the app and on Telegram on every buy and sell, so you watch your rule play out live before you trade it yourself.

What you set

  • Which market. One market, or every market in its series, such as Bitcoin every 15 minutes.
  • When it buys. Yes reaches your price, or falls a set number of points.
  • When it sells. A set number of points above your entry to take profit, or below it to cut the loss.

Prove it before it trades

Every bot earns its record before it spends a dollar. The builder replays your trader or your signal at the size you will actually use on Kalshi markets that already settled. A signal is scored on every matching trade from the last 90 days and then checked on a recent stretch it never trained on, so an idea that only worked in the past gets flagged before it runs.

Then the bot runs on paper against live Kalshi trades, filled at the price and fee a real order would get, and scored as each market settles. When the record earns it, you promote the same bot to live from its own page, without rebuilding anything. How paper orders fill is covered in Kalshi paper trading.

Live on your own Kalshi key

A live bot places orders through your own Kalshi API key, encrypted at rest and revocable from settings, inside a maximum per trade and a maximum per day. Your money never leaves your Kalshi account. The bot sizes down to the depth in the book rather than pushing through a thin market, and every trade it takes or skips is logged with the reason. What happens in the seconds after a trade prints is on prediction market Autopilot.

Drive a Kalshi bot from code or an agent

A signal you build here is also a strategy in the Rivo REST API and a tool call away in the MCP server, so an agent can draft a Kalshi signal, backtest it and read the result in one conversation. If you would rather write the whole bot yourself in Python against Kalshi's own API, the walkthrough is how to build a Kalshi trading bot.

Frequently asked questions

What is a Kalshi trading bot?

A bot that makes Kalshi trades for you when something happens. In Rivo it trades when a Kalshi trader you chose opens a position, or when an incoming trade fits a signal you built. It can alert you, trade on paper at your size, or place a real order through your own Kalshi API key.

Do I need to write code or host anything?

No. The builder is three screens and the bot runs on Rivo's side. If you do write code, the same bots are available through the REST API and the MCP server with the guardrails already built.

Is this an arbitrage bot?

No. Rivo does not run cross-venue arbitrage, market making or latency strategies. A Rivo bot copies a trader or trades a signal over incoming trades. If you want a Kalshi arbitrage bot you want a different product.

How does a live Kalshi bot place orders?

Through your own Kalshi API key, which you connect in settings and can revoke at any time. The key is encrypted at rest and wiped when you disconnect. Funds stay in your Kalshi account, Rivo cannot withdraw them, and there is no Rivo wallet to fund.

Can a Kalshi bot trade the 15 minute crypto markets?

Yes, as a market bot. Point it at a 15 minute series such as Bitcoin, set the price that makes it buy and the move that makes it sell, and it rolls to the next market each time one settles. A market bot keeps a paper record and messages you on every buy and sell.

What does the backtest show for a Kalshi trader?

It replays their recorded trades at your chosen size over the last 7, 30 or 90 days, a year, or their whole record with us, and shows the record, the return and the risk. For a signal it scores every matching Kalshi trade from the last 90 days and splits the window into a training part and a validation part, so a signal that only worked in the past is flagged before it runs.

How much does it cost?

Everything, including live bots, is part of the $15 a month subscription. Just one trade can pay for it. There is no charge per bot, no cut of your trades, and no compute billed separately. Kalshi's own trading fees apply and are paid to Kalshi.
