# BetImpact

> The book knows what you've lost. Now you do too. BetImpact is a betting transparency terminal that puts your action across DraftKings, FanDuel, Kalshi, and Polymarket on one board, shows the cut the book takes on every line before you tap, and keeps the real up-or-down number, not just your win rate.

BetImpact puts every platform's quote for the same outcome on one board. It strips the vig with a standard devig calculation (fair probability = your side's implied probability divided by the market overround), shows the expected value of any bet in dollars, and flags when platforms disagree; a 4.2 point spread on the same moneyline is common. It records your true profit and loss net of all fees, not your win rate, and detects tilt patterns such as chase sequences and late-night loss clustering before they get expensive. The product never sells user betting data to sportsbooks or data brokers.

Pricing is free during beta with the full terminal included. Waitlist members lock beta pricing when paid plans arrive. No card is required to join, and the product is pre-launch with early access opening in waves.

BetImpact serves recreational bettors who want receipts on what betting costs, serious high-volume bettors who line shop, prediction market users on Kalshi and Polymarket, sports fans, data analysts, concerned family members, and researchers studying betting behavior.

For AI agents, BetImpact exposes a Model Context Protocol (MCP) server over streamable-HTTP transport with no authentication (the tools are public). The server is mounted at /mcp, so the JSON-RPC endpoint lives one level deeper, at https://betimpact.app/mcp/mcp; point streamable-HTTP clients at that full path. Two tools are available via the standard tools/list call. `get_product_info` returns the product name, tagline, description, benefit list, pricing, and launch status. `submit_interest` joins the waitlist on a user's behalf (email, name, persona, message); valid persona values are recreational_bettor, serious_bettor, prediction_market_user, sports_fan, data_analyst, concerned_family, researcher, and other.
