# Connect ChatGPT To Live Prediction-Market Edge Data (One URL, No Install) *By The 7 Oracles, The PredictionMarketsPicks Oracles — The 7 Oracles at PredictionMarketsPicks* ChatGPT can call a prediction-markets quant desk directly — 25 tools for Kalshi and Polymarket analysis, including a combo grader that renders its own card inside the chat. One URL, 18 tools callable with no key. - Source: https://predictionmarketspicks.com/articles/connect-chatgpt-to-prediction-market-edge-data - Published: 2026-08-02 --- Most people use ChatGPT for prediction-market research the slow way: paste a price in, describe a situation, get an answer that *sounds* quantitative, and hope the model did the arithmetic right in its head. Sometimes it did. You will not reliably know which times. There is a better wiring. ChatGPT supports remote MCP connectors — the same open standard Claude uses — which means it can call our quant desk directly. Twenty-seven tools, the same models behind our public [tool pages](https://predictionmarketspicks.com/kalshi-analysis), answering inside the conversation. This is the setup guide, with real output from the live server. ## One URL In ChatGPT, custom connectors live behind developer mode (a paid-plan feature — Free accounts can't add them yet): 1. **Settings → Connectors** — enable developer mode under advanced settings. 2. Add a custom connector with this URL: ``` https://predictionmarketspicks.com/api/mcp/mcp ``` That's the entire install. It's a hosted Streamable HTTP endpoint — no download, no local process, no key to start calling. We're on the official MCP registry as `com.predictionmarketspicks/quant`, and the identical URL works in Claude and Cursor if you run more than one assistant. ## The showcase: a combo that grades itself The tool built for ChatGPT specifically is `combo_edge`. It ships as an MCP App — the result can render as a card inside the chat, not a wall of numbers. Here's a real exchange, real output: > **You:** Three legs at 62, 55 and 70 cents. Correlation-aware, I make the joint probability 28 percent. The platform is quoting me +320. Worth it? ChatGPT calls `combo_edge` and gets back: ```json { "verdict": "SMASH", "ev_pct": 17.6, "fair_american": "+257", "fair_band": { "low_american": 228, "high_american": 291 }, "offered_american": "+320", "negative_correlation_trap": false } ``` Fair value on your 28% is +257, the acceptable band tops out at +291, and the venue is paying +320 — a 17.6% expected-value overlay, with the correlation-trap flag explicitly clean. That's a seven-tier verdict (SMASH / PLAY / LEAN / RISK / NO_VALUE / PASS / RUN) computed against the quote your platform actually pays, never against the naive product of the leg prices — which no venue pays, and which is the mistake that makes most multi-leg positions look better than they are. Note the division of labor: *you* brought the correlation judgment (the 28%). The server brought the pricing math. ChatGPT just carried the conversation. ## What "live" means here The calculators are stateless — they compute from your inputs, free, instantly, no key. The *live* layer is different, and we'd rather explain it straight: - **`edge_alerts`** is the feed our models write on Kalshi — weather, bitcoin, silver, gold, oil, mispricings. Every alert carries feed, tier (SPECULATIVE / MODERATE / STRONG), side, price in cents, model probability, edge in percentage points, and a market link. **No key: the identical feed, delayed 24 hours, thesis stripped.** That delay is deliberate — it lets you audit whether the signals were any good before paying for them to be fresh. - **The fantasy draft tools** sit in between. Every one answers with no key, and `player_outlook` / `compare_players` are never capped. The list-shaped ones return a genuinely useful slice anonymously — the top 12 of the board, the top 3 available, 3 sleepers and 3 busts — and a [free key](https://predictionmarketspicks.com/mcp/unlock) lifts those to 50, 10 and 10 for an email, no card. - **A Pro key** turns the feed real-time and unlocks the live model tools: `find_arbitrage` (cross-platform gaps), `market_pulse` (macro composite), `commodity_edge`, and the NFL edge models. Everything returned is derived output — edges, tiers, model probabilities, sizing. Analysis, not a data feed, and every result links back to its tool page so you can check the working. ### Prompts worth stealing - *"Any edge alerts on Kalshi in the last day? Weather only, MODERATE or better."* — `edge_alerts` with filters. - *"Contract at 62 cents, I say 71 percent. Edge and half-Kelly size on $2,000."* — `calculate_ev` then `kelly_size`, chained in one breath. - *"How often does a market priced like this actually resolve yes?"* — `base_rate_gap`, the tool that argues with you. - *"Grade this quote against fair value before I touch it."* — `combo_edge`, every time, no exceptions. ## The honest limits **Probability inputs are percentages.** Pass `71`, not `0.71`. The server rejects fraction-looking inputs with a correction rather than guessing at what you meant — a wrong-but-confident answer is worse than an error. **The delayed feed is genuinely delayed.** If you ask for alerts on a quiet stretch, you may get zero back. That's the honest shape of a real feed, not a malfunction — and it beats a feed that invents signals to look busy. **ChatGPT still picks the tools.** It decides what to call and what to pass. It's good at this and not perfect; if a number looks strange, ask it to show the tool call. The inputs are usually where the problem is. ## Why this exists We think of it as the first prediction-markets quant desk your AI agent can call. The people who win in these markets are the ones who run small arithmetic consistently — every market, every time. Wiring the desk into the assistant you already talk to removes the last excuse not to. The endpoint is live: `https://predictionmarketspicks.com/api/mcp/mcp`. Full tool list and per-client setup on the [MCP page](https://predictionmarketspicks.com/mcp), and the free feed is browsable at [/alerts](https://predictionmarketspicks.com/alerts) if you'd rather look before you connect. *Trade responsibly.
