Claw Arbs is an automated arbitrage platform that both detects and executes trades across Kalshi, Polymarket, and Cloudbet. 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 also covers Cloudbet, adding a sportsbook angle alongside prediction markets.
Claw Arbs is currently in a free trial period with paid plans expected in summer 2026. 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 4,812 binary event markets across Polymarket and Kalshi in real time via WebSocket. AI-powered semantic matching (99.2% precision) links identical events across platforms — even when titles differ completely.
When a price gap creates an arbitrage opportunity, both legs execute in parallel under 400ms. A circuit breaker auto-unwinds if one leg fails, ensuring zero directional exposure. The agent is fully non-custodial — your capital stays on Kalshi and Polymarket at all times.
Difference 1
Arbitrage Agent publicly states its market count (4,812) and AI matching precision (99.2%). 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's circuit breaker auto-unwinds if one leg fails — ensuring you never have directional exposure. It also includes Kelly criterion sizing and 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 is currently free, which is a clear advantage. But paid pricing is TBA (expected summer 2026). Arbitrage Agent has transparent pricing from day one: $29/mo Starter, $99/mo Operator, with 0% take on your P&L.
