Claw Arbs is an automated arbitrage platform that both detects and executes trades: its membership page lists automatic two-leg arbitrage execution, three detection engines and paper and live modes per agent. It launched around April 2026 — the same timeframe as Arbitrage Agent.
The platform uses WebSocket connections for fast odds detection (~20ms) and a 14-step validation pipeline before executing trades. It lists 12 pre-installed venues and lets you add your own bookmakers with point-and-click calibration.
Claw Arbs sells a single membership: a membership; when we last read its membership page the early rate was €250/month (€300 standard), excluding VAT, with a 7-day free trial. We could not confirm the current price on 4 November 2026, so check its pricing page. It offers a suite of free calculators (odds converter, EV calculator, Kelly calculator, hedge calculator, arbitrage calculator) and has an active blog and YouTube channel.

Arbitrage Agent monitors thousands of binary event markets across Polymarket and Kalshi continuously. AI-powered semantic matching — every pair validated before it goes live — links identical events across platforms — even when titles differ completely.
When a price gap creates an arbitrage opportunity, the opportunity appears in your live feed with both legs ready to place. Automated parallel execution (with a circuit breaker that auto-unwinds if one leg fails) is in final testing and rolls out to Operator subscribers first. The agent is fully non-custodial — your capital stays on Kalshi and Polymarket at all times.
Difference 1
Arbitrage Agent publicly documents how its matching works — AI semantic matching with resolution-criteria checks, and validation of every pair before it goes live. Claw Arbs does not disclose how many markets it monitors or its matching accuracy. When choosing an automated trading tool, transparency about what the system actually does matters.
Difference 2
Both platforms have safety mechanisms, but they work differently. Arbitrage Agent includes Kelly criterion sizing, and its automated execution (in final testing) is designed with a circuit breaker that auto-unwinds if one leg fails, to limit directional exposure, plus a kill switch. Claw Arbs uses a 14-step validation pipeline that checks trades before execution.
Difference 3
Arbitrage Agent is explicitly non-custodial — your capital stays on Kalshi and Polymarket at all times, and the agent only has trade-execution API permissions. Claw Arbs' custody model is not publicly documented.
Difference 4
Claw Arbs ships with automatic execution today, at a membership price that was €250/month (early rate, unconfirmed today) excluding VAT. Arbitrage Agent Starter is $29/mo, $99/mo Operator (Operator is coming soon) — with 0% take on your P&L, but it guides your orders rather than placing them for you; automated execution is in final testing.
