What Is a Polymarket Clone Script?
A Polymarket clone script is ready-to-deploy software for a prediction market: users trade shares in the outcome of a real event, each share paying out one unit of stablecoin if that outcome occurs and nothing if it does not. Share prices therefore read directly as probabilities, and the market itself becomes a live forecast.
The trading engine is the easy half. The hard half is resolution: deciding what actually happened, in a way participants accept when money is on the line. A platform is only as credible as its worst-resolved market, and one bad resolution destroys more trust than a hundred clean ones build. For the wider category, see our prediction market development page.

Get a Free Live DemoResolution Is the Whole Product
Every prediction market platform eventually lists a market whose outcome is genuinely contested: an ambiguous rule, a source that changes its wording, an event that half-happens. What you do in that moment determines whether traders come back.
Ambiguity is not an edge case; it is the normal case at scale. Markets that were obvious when they were written become disputable once real money sits on both sides, and the only defence is rules written before the fact and a process nobody can quietly override.
Precise rule text with the resolution source, timing and edge cases named in the market itself, not implied.
Named resolution sources committed at creation, so nobody chooses a favourable source after the fact.
Bonded disputes so challenges cost something and frivolous disputes do not clog the process.
Escalation with a clock a defined challenge window, adjudication step and final settlement deadline.
Invalid and void handling a defined path for markets that cannot be fairly resolved, with collateral returned.
Public audit trail every resolution, dispute and decision recorded and inspectable.
We build the resolution and dispute system as a first-class part of the platform, with the rule template library and adjudication tooling included. Getting this wrong is the failure mode that no amount of trading volume recovers from.

Request a Feature PlanHow Polymarket Clone Script Is Put Together
The modules above map onto these layers. Each one ships with its own tests, documentation and runbook, so nothing arrives as a black box you inherit without an explanation.
Requests flow down, settlement and events flow back up. Every boundary carries logging, so a failure is traceable to a layer instead of guessed at.
Chains and Assets We Work With
Settlement asset and chain choice follow oracle availability and cost per resolution. A market that cannot be settled cheaply and verifiably is a dispute waiting to happen.
How We Build Your Platform
Resolution design leads the build, because it constrains everything from market templates to contract structure.
Market and resolution design
Categories, rule templates, resolution sources, dispute mechanics and limits.
Output → market rulebook and resolution specification
Regulatory scoping with your counsel
Where you can operate, what you can list, what verification each tier needs.
Output → jurisdiction and feature restriction matrix
Contract and engine development
Outcome tokens, collateral, matching layer and settlement written and tested.
Output → contract suite plus matching engine with load tests
Independent audit
Third-party contract review plus penetration testing on the off-chain layer.
Output → audit report with critical and high findings remediated
Launch and market operations
Deployment, seeded launch markets, liquidity plan, monitoring and adjudication rota.
Output → live platform with runbooks and escalation paths
Settlement chains and assets
Development Timeline
| Scope | Timeline | Includes |
|---|---|---|
| White label prediction market | 5 to 7 weeks | Rebranded platform, standard categories, single chain |
| Standard custom platform | 10 to 14 weeks | Custom markets, order book, resolution and dispute flow |
| Platform with full compliance | 4 to 6 months | KYC tiers, geo-fencing, reporting, audit cycle |
| Multi-chain platform with mobile apps | 6 to 9 months | Several settlement chains, native apps, market operations tooling |
What extends the timeline: compliance depth, which is the single largest variable; oracle and dispute infrastructure; the matching layer, which needs load testing rather than functional testing alone; and audit remediation, which is not compressible.
Revenue Models
| Model | How It Works |
|---|---|
| Trading fees | Taker or spread fee on matched volume |
| Settlement fee | A cut of winning payouts at resolution |
| Market creation fees | Charges for listing user-proposed markets |
| Market maker programme | Rebates funded from fee revenue to deepen books |
| Premium features | Advanced analytics, higher limits, API access |
| Data licensing | Selling probability and volume data feeds |
| White label licensing | Licensing the platform to other operators |
Fee design interacts directly with market quality: fees that are too high widen spreads and destroy the forecasting signal the platform exists to produce. We build fees as configurable per-category parameters.

What Our Clients Say
Operators who launched with us, in their own words. Hover to pause.
A members-only NFT marketplace for Digital Freemasonry
Digital Free MasonryNFT marketplace · delivered and liveNext phase in progress: the ODFT Token and the MasonicVerse platform.
Working with Coinsclone has been one of the best professional experiences I have had in the blockchain industry.
From the very beginning of our NFT Marketplace project until its successful completion, the entire team demonstrated exceptional technical expertise, professionalism, patience, and commitment. Every stage of development was handled with great attention to detail, and every challenge we encountered was approached with a solution-oriented mindset.
Read the full client note
Our project was far from a standard NFT Marketplace. It included custom blockchain architecture, Polygon integration, ERC-721 and ERC-1155 standards, royalty implementation, token-gated access through Masonic Passport, multiple payment methods, marketplace customization, advanced testing, and many unique business requirements. Throughout the entire process, the team consistently delivered high-quality work while maintaining clear communication, transparency, and a strong commitment to excellence.
I would especially like to express my sincere appreciation to Mr. Jeeva, Mr. Bala, Mr. Saravanan, Mr. Veeramani, Mr. Akshay, and the entire development team for their outstanding support, professionalism, responsiveness, and dedication throughout the project. Their technical expertise, patience, and willingness to understand even the most complex business requirements gave us complete confidence during every phase of development.
What impressed me the most was not only their excellent blockchain development skills, but also their ability to understand our vision and transform it into a secure, scalable, and highly professional NFT Marketplace.
For me, Coinsclone is not simply a software development company — they are a trusted long-term technology partner. After successfully completing our NFT Marketplace, we are now preparing to continue our collaboration on the next major phase of the Digital Freemasonry ecosystem, including the development of the ODFT Token and the future MasonicVerse platform.
I highly recommend Coinsclone to anyone looking for a reliable, experienced, and highly professional blockchain development company. They have earned my complete trust and respect, and I sincerely look forward to working with them again on future projects.

Frequently Asked Questions
What is a Polymarket clone script?
Ready-to-deploy software for a prediction market platform where users trade shares in real-world event outcomes. Each share pays one unit of stablecoin if the outcome occurs and nothing otherwise, so prices read directly as probabilities.
How does event contract pricing work?
A share that pays one dollar on a yes outcome trading at 62 cents implies a 62% probability. Traders buy and sell those shares like any other asset, and the price moves as opinion and information change. The market price is the forecast.
How are markets resolved?
Against a resolution source named in the market rules at creation, machine-read where possible. Contested outcomes go through a challenge window with bonded disputes and an adjudication step, with a defined void path for markets that cannot be fairly settled.
Why is resolution the hardest part?
Because at scale, ambiguity is the normal case, not the exception. Rules that looked obvious become disputable once real money sits on both sides. Precise rule text, named sources committed up front and a process nobody can override quietly are the only defences.
Do you use an order book or an AMM?
Usually a hybrid: an off-chain order book for matching speed and price granularity, with on-chain settlement so positions and payouts stay verifiable. AMM-based pricing is simpler to launch and gives worse spreads on low-volume markets.
How do you get liquidity into new markets?
Through seeded positions and a market maker programme funded from fee revenue. This matters more here than on a spot exchange: an event market with no depth produces no meaningful probability, which is the product itself.
Is a prediction market legal to operate?
It depends entirely on jurisdiction, market category and how contracts are structured, and in several countries event contracts are regulated as derivatives or as gaming. We build the technical compliance layer — geo-fencing, KYC tiers, category restriction, reporting — to the specification your legal counsel provides. Licensing and legal opinions remain with them.
What settlement asset should I use?
A stablecoin, typically USDC, on a low-fee chain such as Polygon, Base or Arbitrum. Volatile collateral makes payouts unpredictable and turns every position into two bets instead of one.
Can users exit a position before the event resolves?
Yes. Positions trade continuously, so users can sell at the current probability, and outcome shares can be merged back into collateral where the full set is held.
How does the platform make money?
Trading fees on matched volume, a settlement fee on winning payouts, market creation fees, premium analytics and API access, data licensing and white label licensing. Fees have to stay low enough not to widen spreads and degrade the forecast.
How long does it take to build?
A white label platform launches in 5 to 7 weeks. A standard custom build takes 10 to 14 weeks. Adding full compliance takes 4 to 6 months, and multi-chain platforms with native mobile apps take 6 to 9 months.
Will I own the source code?
Yes. Contracts, matching engine, front end and infrastructure transfer to you on delivery, with no licensing dependency on Coinsclone.
