Sonist 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.
