Build a Clone App Like Kalshi
A forecasting interface concept in which members see questions, record a forecast with sample points and review how a question was resolved. It is a non-monetary design exercise, not a trading product.
Original UI concept, not a finished product or a reproduction of Kalshi.
What this concept is
Use this to explore question design, probability history views and the resolution and dispute flow without handling money. It suits research, education and community forecasting ideas. Any scope that involves real money is a different project that begins with legal feasibility, not with screens.
This page outlines a custom approach to prediction market app development: a narrow first release you can put in front of real users, then extend once the core loop is proven.
Original narrow MVP flow
One path through the product, in order. Everything else waits until this works.
- Member browses open questions with clear closing times.
- Member records a forecast using sample points only.
- The question page shows how the group view changed over time.
- At close, the stated resolution source decides the outcome.
- Members can read the resolution note and raise a dispute.
Original concept screens
Illustrative UI concept images for a custom build, with sample content. They are not screenshots of any existing app and do not show a working product.

What drives the cost
A written quote starts with an agreed scope. These are the main decisions that shape the estimate for this kind of app.
Question and resolution tooling
A disciplined authoring and resolution workflow is most of the back-office effort.
Data provenance
Linking each question to a trustworthy source, and storing evidence, adds design and storage work.
Audit and dispute handling
An audit trail and review queue are needed for credibility.
Moderation
Question wording and community content need review.
Dependencies and risks
Things outside the interface that decide whether this kind of product works.
Legal feasibility comes first
Real-money prediction or trading is regulated and varies by jurisdiction. This concept includes no real money, no trading and no claim of legal clearance. Take legal advice before any real-money scoping.
Resolution disputes
Ambiguous questions cause arguments. Wording rules and sources must be agreed in advance.
No returns implied
Sample points have no monetary value and nothing here suggests profit.
Data quality
A wrong or late source undermines trust in every result.
Questions buyers ask
Is this a trading or betting app?
No. The concept is a non-monetary forecasting interface with sample points. It involves no real money, no trading and no returns.
Can you build a real-money prediction market?
That would be a separate scoping exercise that starts with legal feasibility and licensing review in your jurisdiction. This page makes no claim that it is permitted anywhere.
Why do resolution sources matter so much?
Every result depends on a named source and a clear rule. Storing the source and an audit trail is what lets members trust and challenge outcomes.
What drives the cost of a forecasting app?
Question and resolution tooling, data source integration, audit and dispute handling, and moderation. These are scoped on a discovery call.
