Why Look for OddPool Alternatives?
OddPool is a cross-market odds comparison and arbitrage discovery tool that helps traders identify pricing inefficiencies across prediction markets, including Kalshi. If you are actively trading on Kalshi — the CFTC-regulated US prediction market exchange — OddPool can surface moments where the same event contract is priced differently across platforms, giving you a potential edge. Traders searching for OddPool alternatives are often looking for tools that fit more naturally into their specific workflow, whether that means a browser extension they can use without switching tabs, an automated scraper they can schedule, or a calculator that helps them size positions once an opportunity is found.
Beyond workflow preferences, the right arbitrage tool depends on how you access Kalshi's Trading API, how frequently you need real-time data, and which other prediction markets you want to monitor alongside Kalshi. Some alternatives specialize in a narrower pair of markets and therefore return cleaner, lower-noise signals. Others offer broader coverage but require more manual interpretation. Evaluating these tools side by side helps Kalshi traders find the setup that matches their trading style, technical comfort level, and time availability.
Best OddPool Alternatives in 2026
PolyArbitrage (Chrome Extension)
PolyArbitrage is a Chrome extension that runs directly in your browser and surfaces arbitrage opportunities between Polymarket and Kalshi without requiring any external setup or API configuration. Unlike OddPool, which operates as a standalone web tool, PolyArbitrage integrates into your browsing session, making it convenient for traders who already monitor markets through a browser. Its focused scope — specifically the Polymarket-to-Kalshi pair — means the signals it surfaces are tightly relevant to that specific cross-market relationship.
Best for: Kalshi traders who frequently compare prices on Polymarket and want a lightweight, no-install-required browser tool.
Polymarket–Kalshi Arb Finder
This Apify actor automates the scanning process by running as a scheduled or on-demand cloud task that checks for arbitrage opportunities between Polymarket and Kalshi. Where OddPool requires you to visit the platform and interpret results manually, the Apify actor can be configured to run at set intervals and export structured data, making it more suitable for systematic or automated trading approaches. It is a developer-friendly alternative for traders comfortable working with cloud automation platforms.
Best for: Technical traders and developers who want to automate arb scanning and integrate results into their own workflows or alerting systems.
ArbBets
ArbBets is a dedicated arbitrage tool built for prediction markets, including Kalshi, and is accessible through the Polymark.et ecosystem. It offers a focused arbitrage-finding experience that complements or competes directly with OddPool's core function of identifying cross-market pricing gaps. Traders who find OddPool's interface or coverage insufficient may find ArbBets offers a useful alternative perspective on the same opportunities.
Best for: Prediction market traders who want a straightforward arb finder with coverage that includes Kalshi as part of a broader market scan.
EventArb
EventArb is purpose-built for event-contract markets, making it a particularly well-aligned alternative for Kalshi traders since Kalshi's markets are structured as event contracts. It scans across multiple event-contract platforms and highlights discrepancies, similar to OddPool but with an emphasis on the event-contract category specifically. Traders who feel OddPool casts too wide a net across different market types may prefer EventArb's more focused approach.
Best for: Kalshi traders who primarily trade event contracts and want an arb scanner that is optimized for that specific market structure.
DeFiRate Prediction Market Calculators
DeFiRate provides calculators and analytical tools tailored to prediction market traders, including those active on Kalshi. Rather than surfacing live arbitrage opportunities like OddPool does, DeFiRate's calculators help traders evaluate odds, size positions, and assess potential returns once an opportunity has already been identified. It functions as a complementary analytical layer rather than a direct replacement for a live arb scanner.
Best for: Kalshi traders who already identify arbitrage opportunities manually and need calculation tools to assess profitability and position sizing.
How to Choose the Right Alternative
Selecting the best OddPool alternative for Kalshi trading comes down to matching the tool's delivery method, market coverage, and update frequency to your actual trading process. A tool that surfaces great signals but doesn't fit your workflow will go unused. Consider the following criteria before committing to any alternative:
- Market pair coverage: Confirm the tool explicitly monitors Kalshi alongside whichever other prediction markets you trade on.
- Delivery method: Decide whether you prefer a browser extension, a web dashboard, a cloud-automated actor, or standalone calculators based on how you currently monitor markets.
- Update frequency: Arbitrage windows on Kalshi can close quickly, so prioritize tools that refresh data in near real-time if you are executing trades manually.
- Technical requirements: Some tools like the Apify actor require configuration and cloud accounts, while browser extensions work out of the box — match complexity to your technical comfort level.
- Complementary vs. standalone use: Tools like DeFiRate calculators work best alongside a live scanner rather than as a replacement, so consider whether you need one primary tool or a combination.
