Matchr.xyz

Matchr.xyz is a cross-platform terminal built to aggregate liquidity from Polymarket, Kalshi and other prediction market venues into a single interface, rather than a Polymarket-only tool. Its own documentation frames the product as an aggregation layer: an AI matching engine identifies equivalent events trading on different platforms, and a routing layer sends an order to whichever venue prices it best at that moment. A trader browses Markets, Matches, Vaults, Rewards and Portfolio panels from one screen instead of holding separate tabs open for every venue.

On Predicts.guru's own index, Matchr.xyz carries a leaderboard rank of #62 by all-time attributed Polymarket volume, with $7.6M routed through its builder code to date. That figure sits alongside a cohort of 0 wallets counted over the last thirty days and 0 fills in the last seven, so a reader should weigh the historical total against how much of that flow is still moving through Polymarket right now.

Matchr's own quickstart reduces onboarding to three steps: connect a wallet, fund it, then trade. A trader can link an existing wallet directly, which keeps signing under their own control, or sign in with Twitter or email, a path the documentation describes only as Matchr handling the complexity on the trader's behalf. The two routes are not the same trust arrangement, and the docs do not say which one a first-time visitor lands on by default.

Once connected, a trader browses matched events across Polymarket, Kalshi and other listed venues in a single Markets and Matches view. The matching engine flags pairs it considers equivalent and the routing layer sends the order to whichever venue it scores as the better price at that moment, which means a trade opened through Matchr's interface does not always settle on Polymarket's own order book. Only the slice that does clear through Polymarket's CLOB under Matchr's builder code shows up in $7.6M and the more recent $0 and $0 figures on this page.

The product pages do not describe Matchr holding trader funds itself between trades; a Portfolio panel reads positions from the connected account rather than a separate in-app balance the operator controls. Matchr's own documentation does not state whether that boundary holds for the Twitter or email sign-in path as well.

• Cross-platform market matching

  An AI engine flags equivalent events trading on Polymarket, Kalshi and other venues, surfacing price gaps a trader would otherwise have to spot by checking each platform separately.

• Smart order routing

  Orders can execute on whichever connected venue the routing layer scores as best at that moment, rather than always filling on Polymarket's own order book.

• Unified markets dashboard

  Markets, Matches, Portfolio and Watchlist sit in one interface, so a trader tracks positions and scans opportunities without switching between separate platform tabs.

Cross-platform spread hunters

They want the Polymarket versus Kalshi price gap the docs describe surfaced automatically, rather than checking each venue by hand.

Twitter or email onboarders

Traders who don't want to manage a wallet directly can start from a social login, trading setup friction for a custody question the docs leave open.

Multi-venue portfolio watchers

Anyone holding positions across several prediction market platforms gets one Portfolio and Watchlist view instead of separate tabs per venue.

Wallet-first Polymarket traders

Traders who prefer linking their own wallet keep signing under their own control, which matters more given the docs stay quiet on the email path's custody.

Matchr publishes no fee schedule of its own. Its documentation frames the product around capturing the price gap between platforms rather than charging a stated commission, so a trader has to infer the real cost from whatever Polymarket's own trading fees and network costs add on top of a fill. That leaves the burden on the trader to judge whether a given match is worth the trade before clicking execute, since the pitch is a good price rather than a posted rate, and there is no rate card here to check that against.

• It puts Polymarket, Kalshi and other prediction markets on one screen, saving a trader from tab-switching to compare prices.
• Its matching engine automates the search for equivalent events across platforms instead of leaving that work to the trader.
• Signing in with Twitter or email lowers the barrier for someone who doesn't already run a Polymarket-ready wallet.
• It carries a leaderboard rank of #62 by all-time attributed Polymarket volume, so the builder code has a track record to check rather than none at all.
• Linking an existing wallet keeps signing under the trader's own control rather than handing it to the app.

• It publishes no fee schedule, so a trader can't price a trade against a stated rate before routing an order.
• Orders can settle on Kalshi or another connected venue instead of Polymarket, so a trade opened here doesn't automatically add to this builder's attributed Polymarket volume.
• The documentation doesn't say whether the Twitter or email sign-in path keeps custody with the trader the way linking a wallet does.
• Attributed volume over the last seven and thirty days reads $0 and $0 against 2026-09-14, so a trader should confirm the builder code is still actively routing before relying on it.

Linking an existing wallet keeps signing with the trader; the Twitter or email path is described only as Matchr handling the setup, and the documentation doesn't say what custody model sits behind that account. The operator publishes no fee schedule, which limits how much a trader can check before routing an order. Because the platform matches and routes across multiple venues, a fill can land somewhere other than Polymarket, so the operational exposure extends beyond whatever $7.6M and #62 on this page measure under Matchr's own builder code.

Matchr.xyz is built for traders who think in spreads across platforms, not just within Polymarket, and its matching engine does the cross-referencing that would otherwise mean checking Kalshi and Polymarket by hand. The catch is that neither its fee structure nor its custody model for social sign-ins is fully spelled out, and the routing logic means a click here doesn't guarantee a Polymarket fill. A trader weighing a leaderboard rank of #62 and $7.6M in history should also check $0 before assuming the flow is active today. Use it for cross-platform opportunity spotting; skip it if a stated fee and full custody are dealbreakers.

• What is Matchr.xyz?

  Matchr.xyz is a cross-platform terminal that aggregates Polymarket, Kalshi and other prediction markets, matches equivalent events with an AI engine and routes orders to the venue it scores as best.

• Is Matchr.xyz safe to use with Polymarket?

  Linking your own wallet keeps custody with you; the Twitter or email sign-in is only described as Matchr handling setup, and the operator doesn't spell out what custody model applies to that path.

• How much does Matchr.xyz charge in fees?

  The operator publishes no fee schedule and instead frames the product around capturing cross-platform price spreads, so trading fees and network costs on the executing venue determine what a trader pays.

• Does Matchr.xyz only trade on Polymarket?

  No. It aggregates Polymarket, Kalshi and other venues, and its routing layer can send an order to whichever platform prices it best, so a trade here doesn't always fill on Polymarket's own book.

• What are alternatives to Matchr.xyz for Polymarket trading?

  Other builders tracked on this leaderboard, ranked by attributed Polymarket volume, are the direct comparison; Matchr.xyz's own position here is #62, worth weighing against how each tool routes orders and what it charges.

• How does order routing work on Matchr.xyz?

  A matching engine flags events it considers equivalent across connected platforms, then a routing layer sends the order to whichever venue scores best at that moment, which can be Polymarket or elsewhere.
