Prediction Markets Pro Alternatives (2026)

Independent analysis and quant tooling for Kalshi, Polymarket, DraftKings Predictions and FanDuel Predicts, published by the analyst collective The 7 Oracles. 25 quant tools on the site, most of them free: EV calculator, Kelly sizing, probability/odds conversion, Bayesian updater, base-rate scanner, a fully-free combo edge builder with a 7-tier verdict ladder, KL-divergence, a cross-platform Kalshi/Polymarket arbitrage scanner, a daily mispricing scan, commodity and metals edge signals driven by options-implied volatility, NFL power ratings and win probability, and a state-by-state legality map. The same engine is exposed to AI agents as a Model Context Protocol server — 23 tools callable from Claude, ChatGPT and Cursor, 16 of them with no API key. Coverage is numbers-first and calibrated: model-vs-market reads, a published graded track record on every signal feed, and explicit methodology on every tool. Prediction markets are treated as event derivatives rather than as a sportsbook — trader, position, contract. Free tier includes the newsletter, daily movers and email-gated tools. Pro is $14.99/mo or $150/yr.

OVERROUND

Profit leaderboards mostly reward bankroll and luck. OVERROUND asks a narrower question: which Polymarket wallets are actually worth watching? It rebuilds the leaderboard from the complete on-chain fill history (488 million fills, more than 700,000 wallets scored across 60+ categories as of July 2026), collapses correlated markets into independent events, removes the structural longshot premium, shrinks small samples toward the category baseline, and ranks wallets within their domain of expertise. Each ranked wallet gets a public calibration record, and every featured alert (the alert stream subscribers receive) is graded in public on the receipts page, losses included. The methodology is published in full, including its limitations. OVERROUND is an information product: it does not execute trades, hold funds, or recommend transactions.

WinWeatherBot

WinWeatherBot is a Windows desktop app that trades Polymarket weather markets automatically. It blends a 138-member forecast ensemble across GFS, ECMWF, ICON and HRRR, weights each model by recent accuracy, and places correlation-sized orders on the CLOB in under 200ms. Self-custody and Microsoft-signed: your Polymarket key stays in Windows Keyring and never leaves your machine.
