Prediction Markets Picks, published under The 7 Oracles brand, describes its tools page as 26 quant tools for Kalshi, Polymarket and DraftKings traders. The free set covers the pre-trade math (EV, Kelly, Bayes updating, Kalshi fees, probability conversion, combo building); the Pro set adds model-driven edge screens and a cross-platform arb scanner.

The feature that separates it from other calculator sites is a hosted MCP server. Claude, ChatGPT, Cursor, Copilot and Gemini can call the free calculators as tools with no API key.

What it does

The tools page groups its inventory into Bread and Butter, Advanced, Utilities and live data widgets. The calculators in the strict sense are free: EV Calculator, Kelly Criterion Calculator, Kalshi Fee Calculator, Probability Converter, Bayes Updater, Kalshi Parlay Calculator, Combo Edge Builder and Conflict Hedge Calculator.

The rest are model outputs rather than calculators: Bitcoin, Gold, Silver and Oil Edge (model-implied probability against Kalshi YES prices, with free 15-minute-market versions), Weather Edge, Base Rate Scanner, KL-Divergence Arb Detector, Theta Edge, Polymarket Mispricing Scanner and the Cross-Platform Arb Scanner across Kalshi, Polymarket and DraftKings.

  • MCP endpoint: https://predictionmarketspicks.com/api/mcp/mcp (Streamable HTTP)
  • Free MCP tools: calculate_ev, kelly_size, bayes_update, convert_probability, base_rate_gap, combo_edge, fed_rate_odds, NFL power ratings and win probability
  • Pro MCP tools: edge_alerts, find_arbitrage, market_pulse, commodity_edge, scan_mispricings, nfl_edge, nfl_prop_edge
  • Rate limits: 300 requests per minute per IP on the free tier, 5,000 requests per hour per key on Pro

Pricing

The tools page and MCP page quote Pro at $14.99 per month; the pricing page quotes $12.50 per month on the $150 annual plan and a $7.50 first-month promotion. Pro unlocks all 26 tools, the Cross-Platform Arb Scanner, Thee Oracle AI picks, the KL-Divergence detector, Weather Edge, Discord edge alerts and an embeddable widget API key.

Enterprise is $4,999 billed annually ($416.58 per month) for API access, multi-domain widget embedding and the option to hide the Powered by The 7 Oracles attribution. Checkout for that tier is by contacting sales.

Venues and data

Kalshi is the center of gravity: the fee calculator, parlay calculator, 15-minute commodity contracts (the page cites the KXGOLD15M series) and Fed rate tracker are Kalshi-specific. Polymarket appears in the mispricing scanner and the arb scanner; DraftKings and FanDuel Predicts appear in the arb scanner and the state availability map.

Where it falls short

The tool count includes trackers, forecasts and picks. If you only want calculators, the free tier already has them and Pro buys you opinions.

The edge tools publish a model's probability against a market price. The page does not publish the models' out-of-sample track record next to the outputs, so you have to calibrate them yourself.

The arb scanner finds the spread. Executing it means opening Kalshi and Polymarket separately, or a cross-venue terminal.

Who should use it

A Kalshi trader who wants Kelly, EV and fee math available inside an AI assistant, and is willing to treat the Pro edge screens as one more input rather than a signal.
