A quick look at the desktop web interface used to monitor opportunities, search markets, and configure alerts.
Arbomen monitors Polymarket and Kalshi simultaneously, identifies equivalent contracts, and alerts you the moment a profitable spread appears — before it disappears.
Join the Beta WaitlistPolymarket and Kalshi list contracts on the same events. Prices diverge regularly. But capturing those inefficiencies requires infrastructure, not attention.
A profitable spread between platforms can close in under a minute as other traders act. Manual monitoring means you are always too late.
Watching two platforms at the same time while calculating cross-platform spreads is not a workflow — it is noise.
The same event is listed under different names and formats on each platform. Identifying equivalences requires semantic analysis, not just text comparison.
Real profitability depends on the full order book. Without bid/ask depth and available liquidity, most signals are false positives.
Connect simultaneously to Polymarket and Kalshi feeds. Ingest quotes, volumes, and order books in real time via WebSocket and REST polling.
A semantic similarity engine identifies equivalent contracts across platforms using token overlap, keyword matching, and date recognition.
For each confirmed pair, compute the spread in both directions using real bid/ask data with three levels of depth and available liquidity.
When the spread exceeds your configured threshold, deliver an instant alert through Telegram, Slack, webhook, or the web dashboard.
No need to register pairs manually. The algorithm identifies equivalences between contracts from different platforms even when names and formats differ.
Spread calculations use real bid/ask data with three price levels. Illiquid markets are filtered out, eliminating false positives before they reach you.
Each monitored pair has its own spread threshold and its own notification channels. A liquid pair at 1%, a thin market at 5% — you decide.
Scripts loaded at startup receive all system events in real time. Implement position sizing, integrate execution APIs, or add custom filters — without touching core code.
Arbomen runs entirely on your machine — no server to deploy or maintain. It connects directly to Polymarket and Kalshi, processes all data locally, and delivers alerts without any intermediary infrastructure. The only external call is for account authentication.
Full-text market search, connection status per platform, pipeline latency, opportunity history, and pair management — all in one web interface.
A quick look at the desktop web interface used to monitor opportunities, search markets, and configure alerts.
Configure any combination of channels. Each monitored pair can have its own set of active notifications.
HTML-formatted messages with full spread details and order book snapshot.
Post directly to any channel via incoming webhook with rich message formatting.
JSON POST to any endpoint. Integrate with trading bots, spreadsheets, or internal tools.
Real-time in-browser toast notifications while the dashboard is open.
You already trade on Polymarket or Kalshi. Arbomen adds a continuous background watch across both platforms and surfaces real opportunities so you can focus on decisions, not data.
Deploy capital in prediction markets with institutional-grade infrastructure. Real order book data, configurable thresholds, multi-user access, and full alert history.
Load JavaScript agents that receive every market event in real time. Build custom filters, position sizing logic, or integrations with your own execution stack — without forking the core.
