PoliticalPredictions.APP with Grok: read the post and the markets it may move side by side

Political posts tend to appear on X first, and Grok lives on X. Add PoliticalPredictions.APP as a custom connector and you can ask which of your prediction markets a post could move, without leaving the conversation.

Key takeaways

The short version.

  • PoliticalPredictions.APP reads public political posts on X and tells your assistant which Polymarket and Kalshi markets you follow could move.
  • Grok's documentation says anyone can add a custom connector by entering an MCP server URL, and this app's connector address is https://politicalpredictions.app/mcp.
  • The app's site says the connector needs no key and no OAuth, so setup is a URL and a name.
  • Matches are conservative: the app prefers no match over a stretch, and every result links back to the post.
  • It is informational only. It never places bets or trades, and it does not say what to buy or sell.

Who it is for

Who is this for?

It is for people who already follow prediction markets on Polymarket or Kalshi and want to understand why a price just moved. If you are the kind of person who sees a political post, then opens two other tabs to find the markets it touches, this saves you the second step.

It also suits reporters, researchers and students of politics who want the post, the matching public contract and a plain-language note in one place. Nothing here needs a login to X, Polymarket or Kalshi: the app reads public posts, not your feed or your follows.

Use cases

4 ways people use PoliticalPredictions.APP + Grok.

  1. Post to markets

    1. Which of my markets could that post move?

    PoliticalPredictions.APP watches public posts from @realDonaldTrump and @WhiteHouse, plus a short list of mapped political accounts such as cabinet members and congressional leaders. For each post it can return the link, the matching public contract with its last price, the recent move and an as-of time, and a short answer.

    Grok is useful here because it is already where you read the conversation. Ask the question in plain words and Grok calls the connector, so the post and the list of markets arrive in the same reply.

  2. Your own list

    2. Keep a list of what I follow

    The app's site shows that you can tell your assistant which topics or markets you follow, and later ask about them in one go. That turns a vague question like what happened today into a ranked answer about the markets you actually watch.

    Because the list lives with the connector rather than in a single chat, you do not have to repeat yourself every time you open a new conversation.

  3. Last 24 hours

    3. What did the White House post today?

    One of the example prompts on the app's site is checking what the White House posted in the last 24 hours. It is a good morning habit: one question, and you see the posts that matched a public market, with links to read each one yourself.

    If nothing matched, the app says so. A named topic has to appear in both the post and the contract, which means a quiet answer is a real answer, not a gap filled with guesses.

  4. Reaction vs record

    4. Check the reaction against the source

    Grok can search X live, so it can show how people are reacting to a post. The app supplies the other half: the post itself, the contracts that share its topic and the price movement with a time. Together you can see what was said, what the markets did and what people made of it.

    Keep the roles separate. The reaction on X is opinion; the app's contract data is the record. It reports both and leaves the judgment to you.

How to

How do I add it to Grok?

  1. Step 1

    Go to grok.com/connectors (see Grok's [connectors documentation](https://docs.x.ai/grok/connectors)).

  2. Step 2

    Choose New Connector, then Custom.

  3. Step 3

    Enter the connector address https://politicalpredictions.app/mcp. The app's site says it needs no key and no OAuth.

  4. Step 4

    Tell Grok which markets or topics you follow, then ask about any post.

Grok's documentation says the server must be reachable on the public internet, which this address is. On Grok Business and Enterprise, a team admin may need to provision connectors first. PoliticalPredictions.APP has no partnership with Grok and is not listed in a Grok catalog; you add it yourself as a custom connector.

FAQ

Frequently asked questions.

Does Grok have this app built in?

No. There is no official listing or built-in integration. You add the app yourself as a custom connector using its MCP address.

Does it tell me what to buy or sell?

No. It is informational only. It is not a sportsbook, pollster, broker or investment adviser, and it never places bets or trades.

Does it read my X feed or my accounts?

No. It reads public posts from a set of political accounts. It never reads your X, Polymarket, Kalshi or brokerage login, and it never posts or sends messages for you.

What if a post matches no market?

You get no match. The app prefers that to a stretch, so a topic must appear in both the post and the contract.

Can I get alerts without Grok?

The app's site describes a free daily email when a Trump or White House post matches a Polymarket or Kalshi market, with one-click unsubscribe. Text alerts are described as rolling out soon.
