How Can I Get a New Prediction Market Listed on Polymarket or Kalshi?

This article describes the public submission guidance available on 28 August 2026. Venue interfaces, review criteria, geographic access, and applicable law can change. A proposal is an intake request for a venue’s market team; it is not a legal opinion, a regulatory approval, or a promise that the market will be created.

1. How to propose a market to Polymarket

Polymarket’s current Help Center says that users cannot create their own markets directly. Markets are created by the markets team with input from users and the community. Its guidance says that a proposal should include the market title, the resolution source, and evidence of demand, and that the best way to propose one is on X by tagging @polymarket. See Polymarket’s market-creation guidance.

To make each requested detail useful to Polymarket’s markets team:

1. Check for duplication. Search existing markets and related events. Explain what is genuinely new: perhaps the date, threshold, jurisdiction, outcome set, or source is different.
2. Market title. Put the proposed market title first. Make it short, neutral, and specific about the event, subject, and timeframe. Avoid slogans and vague wording; use the same terms as the proposed resolution source so the title describes a question the source can actually answer.
3. Resolution source. Name the specific official source that should determine the outcome and include the relevant official link. Identify the exact publication, page, dataset, or field that will provide the decisive result, rather than linking only to a general homepage or a secondary summary.
4. Evidence of demand for trading that market. Include concrete evidence of expected demand or trader interest, such as relevant discussion, a decision deadline, a recurring event, or a clearly identifiable audience. Explain why that evidence points to interest in this specific market; it is not the same as claiming that the market is guaranteed to be popular.

Polymarket’s public guidance describes this as a suggestion to its markets team, not a self-service creation flow. Do not confuse it with Polymarket’s separate resolution process: after a market already exists and its event is complete, resolution is handled under the market’s pre-defined rules and oracle process. The Polymarket resolution documentation concerns that later step, not new-market intake.

Market title: Will [specific event] happen by [date]?
Resolution source: [exact official source and page/data field]
Evidence of demand for trading that market: [relevant discussion, decision context, or identifiable audience]

2. How to propose a market to Kalshi

Kalshi’s current Help Center directs users with an entirely new market idea to its market suggestion feed. For the market definition itself, Kalshi’s Market FAQs are the clearest current reference: a suggestion should include a clear, objective event definition and settlement criteria, reliable settlement data sources, a proposed timeframe or expiration, and why traders would find the market valuable. The separate Suggesting a New Market page explains the submission route and confirms that Kalshi reviews ideas for CFTC compliance, manipulation risk, and user interest; not every suggestion will be listed. See also the current Help Center guidance above.

For a practical Kalshi submission:

1. Check for duplication. Search Kalshi for existing markets and related questions. Explain what is genuinely different, such as the date, threshold, jurisdiction, outcome set, or source.
2. Use objective, testable language. Define the event or measurement so the outcome is not dependent on a reviewer’s opinion about what “counts.” Specify thresholds, units, dates, and geographic or categorical boundaries.
3. Describe settlement before describing the story. Lead with the source agency or publisher, the exact data point, the publication schedule, and the rule for a correction or delay. A compelling topic does not compensate for an unclear settlement rule.
4. Give a realistic expiration. State the proposed close or expiration date and allow time for the source to publish a finalized result. The displayed close time and the later determination time may differ, so do not treat them as interchangeable.
5. Explain the trader value. Identify why the question is timely, who may follow it, and what information would make it useful. Keep this separate from a promise about trading volume or price.

Kalshi’s older official explanation of its market-creation process describes a proposal being researched and reviewed by a Contracts Team, with a Product Certification setting out detailed terms if the idea passes review. That description is useful background, but the current Help Center is the better source for the submission route and the information to include. See Kalshi’s explanation of where markets come from.

3. What “listed” does—and does not—mean

A venue’s decision to create or list a market is not a general determination that the idea is lawful everywhere. Polymarket and Kalshi operate under different structures, rulebooks, access conditions, and compliance processes. A venue may decline a question because it is difficult to resolve, vulnerable to manipulation, duplicative, outside its product scope, or not useful to its audience. Those reasons are not interchangeable with a legal opinion.

Before submitting a proposal, separate four questions:

• Can the event be defined precisely?
• Can an independent reader determine the outcome?
• Would the venue consider the question suitable and useful?
• What legal, regulatory, tax, access, and trading rules apply to the specific venue and participant?

This article addresses the first three as a specification and venue-intake matter. It does not answer the fourth. Legal, regulatory, tax, and market-access questions require review by the responsible organization and qualified advisers.
