Prediction marketplaces are no longer niche they have become powerful tools for decision-making, where users trade on real-world outcomes such as elections, sports results, crypto movements, and global events.
Polymarket showed that crowd intelligence combined with financial incentives can generate highly accurate forecasts. For entrepreneurs and companies, this opens a major opportunity but building such a platform from scratch involves complex technology, long development cycles, and high costs.
A polymarket clone script solves this challenge. It provides a ready-made, tested framework that allows businesses to launch their own prediction marketplace quickly, securely, and at a controlled budget without compromising quality or scalability.

How Does a Polymarket Clone Script Work?
A Polymarket clone script is where users trade on real-world events. It uses blockchain, smart contracts, and data oracles to automate trading, settlement, and rewards. Here's the process:
Step 1: Market Creation
Who creates it: Admins or authorized users.
What happens: A prediction market is defined around a specific event. For example:
Will Candidate X win the 2026 election?
Will Bitcoin reach $100K by June?
Key details included:
Event title and description
Outcome options (Yes / No or multiple-choice)
Start and end date/time of the market
Oracle or data feed that will verify the outcome
Market fees (if applicable)
Behind the scenes:
Smart contracts are automatically created for each market. These smart contracts hold funds, manage trades, and enforce rules without manual intervention. This ensures trust and transparency.
Step 2: User Participation (Trading Begins)
Who participates: Traders, crypto enthusiasts, or anyone with access to the platform.
What happens: Users deposit funds into the platform via their crypto wallet.
How trading works:
Users buy “Yes” or “No” shares based on their prediction.
Each share represents a stake in the outcome.
Prices change as more users buy shares, reflecting market sentiment.
Behind the scenes:
Smart contracts track each user’s trade in real time. The contract also ensures users cannot withdraw funds before market closure if the platform rules require it.
Step 3: Real-Time Trading & Price Updates
Price dynamics:
If many users buy “Yes,” the price of “Yes” shares increases.
If demand drops, the price falls.
User strategies:
Users can sell shares before the event ends to lock profits or cut losses.
Others can enter new trades as prices fluctuate.
Behind the scenes:
The platform automatically updates prices based on supply and demand algorithms coded into smart contracts. No manual intervention is needed, and the market is transparent for all users.
Step 4: Event Settlement
When it happens: Once the event ends or the outcome is confirmed.
How it happens:
Oracles fetch verified data from trusted external sources (like sports APIs, election results, or financial data providers).
The smart contract receives the outcome and determines winning shares.
Behind the scenes:
Smart contracts validate the oracle data and prepare payouts for winning users. This prevents disputes and ensures that outcomes are fair and tamper-proof.
Step 5: Automated Payout
Who gets paid: Only users who purchased shares aligned with the correct outcome.
How much: Payouts are proportional to the shares owned and the market price at the time of settlement.
User experience:
Winners see funds credited directly to their wallets.
No manual processing or delays.
Behind the scenes:
Smart contracts calculate profit distribution automatically:
Total pool = all losing + winning funds
Winners’ share = (winning shares / total winning shares) × total pool
Fees (if any) are deducted automatically by the platform.
This automation ensures accuracy, speed, and trust.
Step 6: Reporting & Analytics (Optional)
Platforms often include a dashboard for users and admins:
Users can track past markets, profits, and performance.
Admins can monitor active markets, trading volume, liquidity, and fees collected.
Behind the scenes:
The clone script collects data in real-time and generates analytics without affecting trading performance.
How Much Does It Cost to Build a Prediction Marketplace Like Polymarket?
The cost of building a prediction marketplace like Polymarket can vary widely depending on the features, technology, security measures, and regulatory compliance you want to include. A basic MVP (Minimum Viable Product) can cost anywhere between ₹20,00,000 – ₹70,00,000. This version includes essential features such as market creation, simple Yes/No trading, wallet integration, and basic smart contracts. It is ideal for startups looking to test the market, engage early users, and validate their business idea without spending heavily.

Adding these features increases development time, requires more experienced developers, and often involves multiple rounds of testing to ensure smooth operation under high traffic conditions.
For an enterprise-grade solution, designed to handle a global audience with thousands of users trading simultaneously, advanced security audits, regulatory compliance across multiple jurisdictions, and premium features like subscription-based markets, costs can exceed ₹2,00,00,000.
