What Rivo does that a venue's own app does not

A venue's app shows its own markets and your account on that venue. Rivo shows every venue side by side and adds the research the venues do not build.

  • Whale trades across venues

    One live tape of large trades on Kalshi, Polymarket, Polymarket US and Gemini, grouped by market, with the money on each side and the trader behind the newest trade.
    Kalshi whale tracker
  • Trader research and leaderboards

    Ranked traders with a profit curve from settled markets, win rate against the odds they paid, results by bet size and a simulator that replays copying them.
    Polymarket leaderboard
  • One market search

    Search every venue at once, open a market's full detail and compare how each venue lists the event.
  • One order ticket

    Market and limit orders on every venue from the same ticket. The ticket walks the venue's order book and shows the fill price, the venue's exact fee, the total and the payout before you send.
  • Parlay slip

    Build parlays from Kalshi, Polymarket and Polymarket US markets. The contract picker offers only legs the venue allows in a combo.

  • Bots with backtests

    Copy a trader or build a signal without code. Replay it at your size on settled markets, run it on paper, then go live on supported venues with per-trade, per-day and loss limits.
    Bot builder
  • Portfolio across venues

    Positions, open orders, balances, exits and copy history for every connected account in one place.
  • Alerts

    In-app and Telegram alerts when a trader you follow opens a position or a bot's signal matches.

  • API, streams and MCP

    A REST API, live SSE streams, outbound webhooks and a remote MCP server for Claude, ChatGPT and Cursor, included in the subscription.

What can you do with a prediction market terminal?

Feature lists all look alike, so here is how people actually use the terminal, step by step. This is what you get for $15 a month.

1. The morning scan in five minutes

  • Open the terminal. The whale tape in the middle groups last night's large trades by market. Each row shows the money on Yes against No, the current Yes chance, the total and the trade count.
  • A market with $80,000 on Yes and $5,000 on No from four different traders tells you more than any headline. Click the chevron to see each trade and who placed each one.
  • The Markets rail on the left ranks what traded most in the last hour. The Traders rail on the right lists who was active, with win rate, return and profit on every row.
  • Narrow the tape with the filters at the top: category, venue, trade size, odds and entry type. Save the filter set you use every morning.

2. Research a trader before you copy one

  • Click any trader's name. A workstation opens with the whole observed record.
  • The profit curve comes from settled markets only, so a trader who is up big on open positions doesn't get ranked on hope.
  • Win rate sits beside the average price paid. A 40% win rate on 20 cent longshots is a winning record. A 70% win rate on 85 cent favorites is a losing one.
  • Results by bet size show whether the trader wins on the big bets or only the small ones. Categories show where the edge lives: sports, politics, crypto or macro.
  • The heatmap shows when in the week the trader trades, in Eastern time. The simulator replays copying them at $25, $100 or $250 a trade over 7, 30 or 90 days.
  • Similar traders open in place, so you compare three candidates in a minute.

3. Build and backtest a bot in three steps

  1. Trigger. Pick one trader, several traders or a signal. A signal filters incoming trades by category, size, keyword, market, entry price and whether the trade opened, added to or flipped a position.
  2. Backtest. Pick a fixed amount per trade or a percentage of the source trade with a dollar cap. The builder replays the trigger at your size on settled markets. Signal bots split 90 days into a training window and a holdout window and flag a signal whose two halves disagree.
  3. Mode. Alerts only, Paper or Live. Paper records every entry at the trader's own price. Live places real orders through your account inside a per-trade limit, a per-day limit and an optional loss limit.

A live bot stops itself when your account runs out of money or a venue key disconnects, sends you one message, and resumes once the problem is fixed. On Kalshi, a live trader bot also sells your share when the trader sells.

4. Place a parlay across one venue's markets

  • Open the search in the header. The market explorer lists every venue's markets on the left.
  • Each row has a + leg button. The contract picker offers only legs the venue allows in a combo.
  • The slip on the right builds the parlay. Parlays run on Kalshi, Polymarket and Polymarket US, one venue per parlay, because the venues do not share accounts.

5. Check your whole book across venues

  • Portfolio lists positions, open orders and balances for every connected account.
  • Open orders cancel or amend from the same screen on venues supporting amend.
  • Copy history shows every trade a bot took and every trade a bot skipped, with the reason, such as a price move past your slippage or a daily limit reached.

What works on each venue

Research, backtesting and paper bots run on every venue. Live trading follows how each venue lets outside software connect.

Account readiness, venue permissions and the limits you configure still apply to every live action.

The venue apps still win on one thing: the venue itself. Deposits, withdrawals, identity checks and account settings stay on each venue. Rivo sits on top of your accounts. It doesn't replace them.

Who uses a prediction market terminal?

  • Kalshi sports traders who want to see which named traders are loading up before a game, and copy the good ones through their own API key.
  • Polymarket wallet watchers who follow a handful of wallets and want a Telegram ping the moment one of them buys.
  • Bot builders who want to test an idea on settled markets at their own size before risking a dollar.
  • Multi-venue traders with money on Kalshi, Polymarket US and Gemini who are tired of three apps and three fee formats.
  • Developers and AI users who want one API key, live streams and an MCP server covering every venue.

If you trade one market a month on one venue, the venue's own app is enough. Rivo pays off when you trade often, across venues, or want to copy people who are better at this than you.

What Rivo does not do

  • Rivo is not an exchange. Rivo holds no funds and takes no side of your trade. Every order goes through your own account on the venue.
  • No live Autopilot on polymarket.com yet. Manual trading from your wallet works today. Automated live trading there is coming soon.
  • No routing between Polymarket and Polymarket US. They are separate companies with separate accounts. Rivo never moves an order from one to the other.
  • No full order-book history product. Rivo records large trades and tracked traders, not every order on every venue.
  • No cross-venue arbitrage scanner. Rivo shows every venue's book in one place. Matching one event across venues is on you. See prediction market arbitrage.
  • No guarantees. A trader's past record does not predict the next trade. The simulator and backtests show what happened, not what happens next.

How Rivo connects to each venue

  • Kalshi: your own API key. It can trade and read your account, but it can't withdraw money.
  • Polymarket US and Gemini: your connected account credentials.
  • Polymarket: your wallet, signing each order in your browser.

Venue fees and venue eligibility still apply on every order.

How much does Rivo cost?

$15 a month, charged at checkout. That covers every venue, bots, alerts, the REST API and the MCP server. The venue's own trading fees stay separate. See Kalshi fees and Polymarket fees for what each venue charges.

How Rivo compares with other tools

Trackers, research sites, terminals and bot builders each cover part of this. The Kalshi trading tools comparison and the bot builder comparison set Rivo beside the alternatives using each tool's own pages. For the venues themselves, see Kalshi vs Polymarket.

Frequently asked questions

What is a prediction market terminal?

One screen for researching and trading prediction markets across venues. Rivo's terminal shows live large trades, markets, ranked traders and your portfolio for Kalshi, Polymarket, Polymarket US and Gemini, and places orders through your own accounts.

What is the best app to trade Kalshi and Polymarket in one place?

Rivo trades Kalshi, Polymarket, Polymarket US and Gemini from one terminal for $15 a month. You connect your own account on each venue, search every venue at once and place orders from one ticket showing each venue's exact fee.

How much does Rivo cost?

$15 a month for the whole terminal, including bots, alerts, the REST API and the MCP server, charged at checkout. Venue trading fees are separate and go to the venue.

Does Rivo hold my money?

No. Rivo is not an exchange or a broker. Orders go through your own venue account: a connected Kalshi API key, a connected Polymarket US or Gemini account, or your own Polymarket wallet in the browser. Your funds stay on the venue.

Does Rivo trade automatically?

Yes, on Kalshi, Polymarket US and Gemini. A bot copies a trader or matches a signal, and live Autopilot places orders through your own account inside per-trade, per-day and loss limits. On polymarket.com Rivo supports manual trading from your wallet, and live Autopilot there is coming soon.

Which venues does Rivo support?

Kalshi, Polymarket (polymarket.com), Polymarket US and Gemini Predictions. Polymarket and Polymarket US stay separate accounts with separate balances. Rivo never routes an order from one to the other.

Does Rivo show who is trading?

On Polymarket and Kalshi, yes. Polymarket wallets are public, and Kalshi shows some traders by name. The Polymarket US and Gemini public feeds carry no trader identity, so Rivo shows those trades without a name.

Is Rivo live or delayed?

Live for subscribers. The terminal streams new trades as they print. The public pages on rivo.markets, such as trader profiles, show the record on a 24 hour delay.

Is there an API?

Yes. A REST API, live server-sent event streams, outbound webhooks and a remote MCP server for Claude, ChatGPT and Cursor come with the subscription. Keys carry read, write or trade scopes and an optional daily spend cap.
