0xc64954680ca66b254563d200fe68065471fd68acd52191b0e4ad3df8b2c8ca94 What is Matchr.xyz?
Matchr (matchr.xyz) is an Arbitrage builder for Polymarket — a cross-platform prediction-market aggregator that searches and compares 1,500+ matched markets across Polymarket and Kalshi, lets users find arbitrage opportunities, compare odds in real time, and execute trades from a single UI. The product also offers USDC-deposit 'Vaults' that run automated strategies across Polymarket and Kalshi. As of May 2026 Matchr ranks #33 all-time on the Polymarket builder leaderboard with $7.63M cumulative routed across 46 users — making it the largest arbitrage-category builder by volume even though daily/weekly/monthly leaderboard ranks are blank (concentrated lifetime activity rather than continuous flow). The single public social handle is @matchrxyz on X. Founders, funding stage, launch date, and pricing are not publicly disclosed. The builder is Polymarket-verified (✓) on builders.polymarket.com.
Matchr (matchr.xyz) is a cross-platform prediction-market aggregator and arbitrage tool. The product searches 1,500+ matched markets across Polymarket and Kalshi — the two dominant prediction-market venues that together account for 97.5% of total prediction-market share — and lets users compare odds in real time, find matched markets, identify risk-free arbitrage opportunities, and execute trades through a unified interface with smart routing.
Its second major surface is Vaults: users can deposit USDC into managed vaults that run automated strategies across Polymarket and Kalshi simultaneously. Matchr is also developing agentic trading infrastructure, with the stated goal of human oversight today and full autonomy in the future — a roadmap consistent with the broader 2026 AI-agent-on-prediction-market trend.
On-chain Polymarket traction: ranked #33 all-time with $7.63M cumulative routed across 46 users — the largest arbitrage-category builder by volume on Polymarket. Notably, the day/week/month leaderboard ranks are all null, meaning recent flow has been minimal and the all-time volume is concentrated in earlier periods. This is consistent with arbitrage opportunities: they tend to come in bursts as new markets launch and spreads converge.
Founders, team composition, funding stage, launch date, and pricing tier are not publicly disclosed on the site. The product is competitive with related arbitrage tools — Dome (YC-backed unified API), ImMike/polymarket-arbitrage (open-source Python bot scanning 10,000+ markets), and Prediedge (real-time analytics) — but Matchr's vault layer is its distinguishing feature.
The only confirmed public channel is @matchrxyz on X. No Discord, Telegram, GitHub, LinkedIn, or Medium links were located on the homepage or in WebSearch.
