Polytrage

Polytrage is an automated arbitrage bot rather than a manual trading interface. Its own product page describes a single engine that ingests order book and tick data by websocket from Polymarket, Kalshi, Opinion Labs, Probable and Predict.fun at once, then uses semantic and rule-based matching to link identical questions priced differently across those venues. When it finds a gap, the system is built to execute the trade itself, at machine speed, rather than surface the opportunity for a human to click.

The site itself is marked coming soon: the only action available to a visitor is leaving an email address for early access, with no dashboard, sign-in or funded account to inspect yet. Despite that, Polymarket's own attribution data ties an all-time volume of $707K to its builder code, placing it #152 on the leaderboard, while the last seven and thirty days both show $0 and $0. A trader evaluating it today is really evaluating a waitlist, not a working terminal.

Trading happens inside the engine, not on a screen a trader operates. Continuous websocket feeds pull order book and tick data from every exchange it watches, and rule-based plus semantic matching links markets asking the same question across platforms. Once a gap between two venues clears whatever threshold the system uses, it fires both legs of the trade itself, aiming to close the position before the price gap does. Orders that touch Polymarket route through Polymarket's own central limit order book like any other order, tagged with Polytrage's builder code for attribution.

What the operator has not published yet is how a trader gets in. The public page collects only an email address for early access; there is no sign-in, no wallet connection flow and no statement of whether the bot holds trading capital itself or trades out of a wallet the trader controls. Anyone signing up today is registering interest in a system whose custody model is still undisclosed.

• Cross-exchange order book scan

  One engine ingests order books from Polymarket, Kalshi, Opinion Labs, Probable and Predict.fun together, so a gap has to open on any one of five venues before it's missed.

• Automated question matching

  Semantic and rule-based matching links the same prediction question when it's listed on different platforms at different prices, without a trader manually pairing markets by hand.

• Tick-level automated execution

  The bot fires both legs of a spotted gap itself over a live websocket feed, aiming to close the trade before the mispricing corrects, with no manual confirmation step.

Automated arbitrage seekers

Fits a trader who would rather have code close a spotted price gap across five exchanges than watch order books and trade it by hand.

Multi-venue prediction market traders

Fits someone already active on Kalshi, Opinion Labs, Probable or Predict.fun who wants one feed comparing prices instead of five separate browser tabs.

Early access testers

Fits a trader comfortable joining a waitlist and testing a system before it publishes fees or a track record beyond its all-time attributed volume of $707K.

Traders needing custody clarity

Fits someone who will not fund a bot until it states plainly whether it ever holds trading capital, since Polytrage has not said so yet.

Polytrage publishes no fee schedule of its own. Attributed volume over the last seven and thirty days sits at $0 and $0, with 0 fills counted in that window, so there is no recent trade flow to measure what trading through it actually costs today. An automated strategy like this typically stacks its own costs on top of anything the tool itself charges: network gas for each leg, Polymarket taker fees, and slippage between the two venues being arbitraged. A spread that looks wide on screen can shrink once every leg is paid for, so anyone signing up should ask directly what cut, if any, the bot takes before funding it.

• Automates the tedious work of watching five prediction market venues for the same question priced apart.
• Pulls order flow from Kalshi, Opinion Labs, Probable and Predict.fun into the same engine as Polymarket, instead of leaving a trader to tab between them.
• Matches identical questions across platforms with rule-based and semantic logic rather than asking a trader to pair markets by hand.
• Aims to execute both legs of a spotted gap immediately over a live feed, which matters for a strategy that depends on speed.
• Carries a rank of #152 and all-time attributed volume of $707K under its builder code, so it is not an entirely untested piece of order routing.

• The product page itself reads coming soon: there is no live dashboard, no funded account and no way to test execution today.
• Publishes no fee schedule, so a trader cannot compare its cost against a stated number before signing up.
• Shows no attributed volume in the last seven or thirty days ($0 and $0), so recent order flow cannot be checked.
• Says nothing yet about whether it holds trading capital itself or trades from a wallet the trader controls.
• Depends on execution speed across five exchanges it does not operate, so a delay on any one leg is outside its control.

Polytrage does not say whether it takes custody of trading capital or executes from a wallet the trader keeps control of, and with the product still gated behind an email signup, there is nothing running yet to inspect for an answer. It carries a verified profile and an all-time attributed volume of $707K tagged to its builder code on Polymarket, which at least confirms the routing has touched the chain before. Operationally, an automated bot trading across five exchanges at once concentrates a lot of exposure in code a trader cannot see, so the custody question is the one to get answered before funding it.

Polytrage is a bet on execution speed and coverage across five prediction market venues, built by traders who would rather let code close a spotted gap than click through it themselves. What is live today is an email signup, not a funded terminal, and the operator has not said what it will charge or whether it ever touches a trader's capital directly. Anyone drawn to automated cross-exchange arbitrage should join the waitlist and ask those questions before funding anything. Traders who need a working product right now, or who want to see recent fills before trusting a bot with capital, should wait for a live release.

• Is Polytrage safe to use?

  Polytrage does not state whether it holds trading capital or trades from a wallet the trader controls, and the product itself is not live yet, so there is nothing running to test that claim against.

• What is Polytrage?

  Polytrage is an automated arbitrage bot that scans Polymarket alongside Kalshi, Opinion Labs, Probable and Predict.fun for the same question priced apart, then executes the trade itself instead of showing it to a trader.

• How does Polytrage work?

  A single engine ingests order book and tick data from every exchange it watches, matches identical questions across platforms, and fires both legs of a spotted price gap automatically over a live feed.

• What fees does Polytrage charge?

  The operator publishes no fee schedule, and with no recent fills to measure a real rate from, a trader has to ask directly what cut the bot takes before funding an account.

• Is Polytrage live yet?

  Its own site is marked coming soon and only collects an email address for early access, even though its builder code already carries an all-time attributed volume of $707K on Polymarket.

• What are the alternatives to Polytrage?

  Predicts.guru ranks every Polymarket builder by attributed volume and recent fills, which lets a trader compare options directly since Polytrage has no live product to test against yet.
