Overview
When evaluating arbitrage tools for prediction markets, the ArbBets vs Eventarb comparison is a relevant one for traders looking to capitalize on pricing inefficiencies across platforms like Polymarket and Kalshi. Both tools are currently in a coming soon stage, meaning they have not yet launched publicly, but each appears to be taking a distinct approach to helping users identify and act on arbitrage opportunities in prediction markets.
ArbBets positions itself as an AI-driven platform focused on surfacing both arbitrage and positive expected value (EV) opportunities, suggesting a more sophisticated analytical layer beyond simple price discrepancy detection. Eventarb, by contrast, markets itself as a free, accessible tool designed to calculate and alert users to cross-platform arbitrage opportunities. Both tools target the growing community of prediction market participants, but they differ in scope, pricing model, and apparent methodology.

When to Choose ArbBets
ArbBets may be the better fit for traders who want more than just arbitrage detection — specifically those interested in identifying positive expected value opportunities using AI-driven analysis. If you are willing to potentially pay for a more feature-rich platform and want a tool that could offer deeper market intelligence across Polymarket and Kalshi, ArbBets appears to be building toward that use case, though its full capabilities and pricing remain to be confirmed at launch.
- You want AI-assisted analysis that goes beyond simple price difference detection to include positive EV opportunities.
- You are comfortable waiting for a potentially premium-tier product and evaluating its pricing once it launches.
- You trade actively enough on Polymarket and Kalshi that a more sophisticated analytical layer could meaningfully improve your edge.
When to Choose Eventarb
Eventarb stands out as the more accessible option, particularly because it is explicitly described as a free tool. For traders who are newer to prediction market arbitrage or who simply want a cost-free way to receive cross-platform alerts without committing to a paid subscription, Eventarb appears to be designed with that audience in mind. Its focus on calculating and alerting makes it a practical starting point, assuming it delivers on its promises at launch.
- You are looking for a free, no-cost entry point into prediction market arbitrage tooling across platforms like Polymarket and Kalshi.
- You prefer a tool focused specifically on cross-platform arb calculations and real-time or near-real-time alerts rather than broader EV analysis.
- You want to test an arbitrage tool without any financial commitment before considering more advanced paid options.
Verdict
Since both ArbBets and Eventarb are currently listed as coming soon with no live websites or confirmed feature sets, any comparison must be treated as preliminary and based solely on their stated descriptions. That said, the two tools appear to serve overlapping but distinct needs: Eventarb has a clear advantage for cost-sensitive users given its free positioning, while ArbBets hints at a more advanced, AI-powered offering that could justify a price tag if it delivers meaningfully deeper analysis. Until both tools launch and can be evaluated hands-on, the honest recommendation is to monitor both, sign up for updates from each, and make a final decision based on actual performance rather than pre-launch positioning.
