Building the Next Polymarket or Kalshi: A Guide to Launching Custom Prediction Markets in 60 Days

Build a Polymarket or Kalshi-style prediction market in 60 days. Get white-label software, full source code, AMM trading engine, settlement ledger, and scalable architecture by Vinfotech.

If you are evaluating a white-label prediction market software provider, searching for a prediction market platform development company, or considering whether you should buy prediction market source code, you are likely discovering that this isn't just about building a website.

You are looking for an end-to-end system that can perform reliably under pressure: Create markets → Take trades → Manage balances → Resolve outcomes → Settle winnings → Stay secure → Scale.

We spent months refining our Prediction Market core so you can launch in just 60 days. Here is the engineering view of how we do it.

What a Modern Prediction Market Platform Actually Includes

This category is not only about UI. It is about the full market lifecycle and trading experience. Whether you are building a Polymarket clone (crypto-native) or a Kalshi-style platform (regulated/fiat), the underlying engine needs to handle these critical flows:

1. Market Lifecycle
  • Market Creation: Categories, outcomes, rules, cutoffs, and metadata.
  • Trading Window: Continuous trading with live price updates.
  • Market Close: Automated trading freeze and final checks.
  • Resolution: Final outcome selection, approvals, and audit trails.
  • Settlement: Crediting winners, closing the ledger, and generating reports.
2. Trading Experience
  • Fast Order Placement: Instant confirmations.
  • Real-time Data: Live prices and interactive charts.
  • Trust Elements: Rules, deadlines, and clear resolution sources to reduce disputes.

If you are comparing vendors, the fastest way to judge depth is to see a working system. Vinfotech can set up a dedicated sandbox for your brand where you can:

  • Create markets and place trades.
  • Test resolution workflows and settlement behavior.
  • Validate the AMM configuration approach for your use case.

Why a 60-Day Launch is Realistic

(When Engineered Correctly)

A 60-day launch becomes realistic when you start with a proven prediction market core and focus your time on what actually blocks launches:

  • Trading reliability under load.
  • Wallet and ledger correctness.
  • Operator tooling and audit trails.
  • Integration readiness for payments and KYC.

Many teams approach this space with a “clone script” mindset and underestimate the hard parts. The winning approach is to start from a refined core, then customize aggressively without breaking correctness.

At Vinfotech, you get a head start on
  • Wallet & Settlement Ledger: Pre-tested for financial accuracy.
  • Admin Console: Mature workflows for market operations.
  • Monitoring: Built-in operational readiness.

You get the benefit of this core plus a dedicated delivery squad.

The 60-Day Engineering Roadmap

A successful launch works when two tracks run in parallel: Core Product Customization and Deployment Readiness. Below is how we typically structure delivery.

Weeks 1-2: Requirements, Sandbox, & AMM Configuration

1) A Dedicated Delivery Squad is Assigned This is not a "single developer" build. We assign a full team that acts as an extension of your company:

  • Project Manager
  • Backend & Frontend Engineers
  • DevOps & QA Engineers
  • UI/UX Designers

2) The Sandbox Environment We create a sandbox environment exclusively for you. This becomes your daily feedback loop where you can experience the product as a real operator.

3) AMM Setup: How we configure it for you At Vinfotech we’ve developed our own Automated Market Maker (AMM) so prices can move even when early volume is low. We don't just give you a generic AMM; we configure it based on your risk tolerance

  • Starting Liquidity: Defining the baseline depth.
  • Price Sensitivity: ensuring large trades don't break the market.
  • Spread & Slippage: Controls for a healthier trading experience.
Weeks 3-6: Customization That Drives Adoption

This is where we make the product "yours" while preserving platform reliability.

Product & UX Refinements
  • Market Catalogue: Categories, search, filters, and trending sections.
  • Trust Elements: Market detail layouts with clear rules and timestamps.
  • Trading Flow: Optimized buy/sell flows and error handling.
Operator Workflows
  • Fast market creation with templates.
  • Clear resolution checklists and approval flows.
  • Risk controls (limits, suspicious activity signals).
Weeks 7-8: Production Readiness & Integrations

Payments & KYC Integration A platform is "launch ready" only when funds move safely. We typically:

  • Integrate the payment gateway of your choice.
  • Link with the KYC provider required for your target region.
  • Validate wallet ledger behavior (deposits, holds, withdrawals).
Hardening & Launch
  • Security: Review of authentication, sessions, and APIs.
  • Load Testing: Simulating peak traffic behavior.
  • App Deployment: We prepare final builds and help you publish to Play Store and App Store.

What You Get at Delivery

At the end of 60 days, you are not just getting a login; you are owning the asset.

  • Full working prediction market platform (Web + Apps).
  • Complete Source Code Handover.
  • Technical Documentation & Deployment Guides.
  • Admin & Operational Training.

This is why many teams that start by searching for a “script” eventually choose a real build and handover instead.

Tech Stack (Typical & Adaptable)
  • Web: React or Next.js
  • Backend: Node.js, Java, or Go (based on performance needs)
  • Realtime: WebSockets for live pricing
  • Database: PostgreSQL (Core Data) + Redis (Caching)
  • Infrastructure: AWS or GCP with Kubernetes

FAQ

How long does it take to build a prediction market?

If you build from scratch, timelines can extend to 6-12 months due to the complexity of settlement and security. With Vinfotech's refined core, a production-ready launch in 60 days is realistic.

A clone script often fails under load or lacks necessary security. Serious operators need a robust engine. With Vinfotech you get a refined core platform, the speed of a script along with the depth of a custom build.

Polymarket vs. Kalshi architecture: Which do you support?

We support both architectures. If you want a crypto-native, decentralized feel (Polymarket style), we use blockchain-based settlement. If you want a regulated, fiat-based approach (Kalshi style), we implement a centralized ledger with robust audit trails.

Will you provide source code?

Yes. Source code is handed over with documentation and training. You own the IP required to run your business.

Do you provide ongoing development after launch?

Yes. We don't just ship and disappear. We work as an extension of your team for ongoing features, new market types, and 24/7 support.
