Why Look for Eventarb Alternatives?
Eventarb is a promising free tool designed to calculate and alert users to cross-platform arbitrage opportunities across prediction markets like Polymarket and Kalshi. However, since Eventarb is currently coming soon and not yet publicly available, traders who need active arbitrage tools today must look elsewhere. Whether you are a casual prediction market participant or a serious trader running automated strategies, finding a working solution now is a practical necessity rather than a preference.
Beyond availability, different traders have different requirements. Some need fully automated execution bots that operate around the clock, while others simply want alerts delivered to a messaging app. Budget, technical expertise, and the specific platforms you trade on all influence which tool fits your workflow. Exploring Eventarb alternatives ensures you are not waiting on the sidelines while arbitrage windows open and close across prediction markets every day.
Best Eventarb Alternatives in 2026
ArbPoly
ArbPoly is a comprehensive, actively available arbitrage platform that continuously scans Polymarket, Kalshi, PredictIt, and other prediction markets for pricing discrepancies, then executes both sides of a trade simultaneously through automated bots. Built on Solana and integrated with Jupiter, ArbPoly achieves execution speeds of around 400 milliseconds, allowing it to capture spreads that slower blockchain-based tools would miss. It operates as a non-custodial platform, so users retain full control of their USDC in connected wallets like Phantom or Solflare, and a real-time dashboard tracks profit, win rate, and execution history.
Best for: Traders who want a fully automated, high-speed arbitrage bot with multi-platform coverage and are comfortable with a paid, infrastructure-grade solution that runs 24/7 without manual intervention.
ArbBets
ArbBets is an AI-driven platform focused on identifying both arbitrage opportunities and positive expected value (EV) bets across Polymarket and Kalshi. By combining traditional arbitrage detection with EV analysis, it targets traders who want more than just risk-free spreads and are also interested in edges based on mispriced probabilities. ArbBets is currently in a coming soon phase, so it is not yet publicly accessible, but its dual focus on arbitrage and EV makes it a differentiated option to watch.
Best for: Prediction market traders who want AI-assisted identification of both pure arbitrage spreads and positive EV opportunities across major platforms once the tool launches.
Polytrage
Polytrage delivers automated arbitrage opportunity signals through a Telegram channel, sending alerts every 15 minutes with detailed bid-ask spread data and direct trading links for relevant crypto markets. This lightweight, notification-based approach makes it accessible to traders who prefer to evaluate opportunities themselves before acting rather than handing execution off to a bot. Like several other options in this space, Polytrage is currently listed as coming soon, meaning it is not yet available for active use.
Best for: Traders who prefer a simple, alert-driven workflow via Telegram and want to make their own execution decisions based on regularly delivered arbitrage signals rather than relying on fully automated bots.
How to Choose the Right Alternative
Selecting among Eventarb alternatives comes down to matching a tool's capabilities to your actual trading needs, technical comfort level, and how much time you can dedicate to monitoring markets. A fully automated bot is not always superior to a well-timed alert service if you are selective about the trades you take. Consider the following criteria before committing to any platform.
- Availability and status: Prioritize tools that are actively live, like ArbPoly, if you need to start trading immediately rather than waiting for a coming soon launch.
- Automation level: Decide whether you want fully automated trade execution or prefer to receive alerts and execute manually based on your own judgment.
- Platform coverage: Confirm that the tool monitors the specific prediction markets you trade on, such as Polymarket, Kalshi, or PredictIt.
- Custody and security: For tools that touch your funds directly, verify whether they are non-custodial and how wallet connections and transaction signing are handled.
- Cost structure: Compare free tools against paid platforms by estimating whether the arbitrage returns realistically justify any subscription or fee cost at your trading volume.
