Probo was one of India’s most popular opinion trading platforms. Users traded predictions on sports and events. The concept was simple. You predicted whether something would happen. You bought yes or no positions. If your prediction was correct you made money. If it was wrong you lost money.
The platform grew rapidly. Millions of users joined. They predicted cricket match outcomes. They predicted stock movements. They predicted political events. The engagement was high because results came quickly. You did not wait weeks for outcomes. You got results within hours or days.
Then everything stopped. India’s new Online Gaming Bill banned money based games. The government classified these prediction activities as illegal gambling under the law. Probo’s real money gaming operations were suspended. The platform that millions used was no longer legal. Users looked for alternatives.

How To Build App Like Probo
1. Market Research and Legal Compliance
Building an app like Probo starts with understanding the market and the law. You must identify whether your target market allows real money prediction trading or only free to play models. Laws differ by country and by state. What is legal in one place might be illegal in another.
Consult legal experts to determine whether opinion trading fits as skill based gaming, prediction market, or falls under gambling law. This classification matters enormously. Skill based gaming is legal in many places. Gambling is heavily restricted or banned. The line between them is often unclear. Legal experts help navigate that ambiguity.
Build in age restrictions from the start. Minors cannot participate in real money gaming. KYC verification confirms user identity and age. Geofencing ensures the app does not operate in restricted locations. These compliance features are not optional. They are required.
2. Prediction Engine
The prediction engine is the heart of the app. Users should be able to trade yes or no or event outcome contracts using virtual currency or tokens. The system must implement real time odds or pricing models driven by user demand and probability algorithms. As more people buy yes the price of yes increases. As more people buy no the price of no increases. The market adjusts constantly.
Settlement logic must work automatically. Once the event outcome is final the system resolves predictions and distributes rewards to winners. This process must be transparent and fast. Users want to know if they won immediately after the event ends.
3. User Accounts and Wallet
Secure signup with email, phone, or social login makes registration easy. The wallet functionality handles deposits, internal tokens, and withdrawals where legal. Users must be able to add money easily. They must be able to withdraw winnings easily. Any friction in these processes drives users away.
Transaction history and clear status of all trades build trust. Users should see every deposit, withdrawal, and trade. Transparency prevents disputes and builds confidence in the platform.
4. Real Time Data Integration
The app needs accurate real time data. Integrate with data APIs to fetch sports scores, financial indicators, crypto prices, or other relevant feed data. The quality of this data determines the quality of the platform. Wrong data leads to wrong settlements. Wrong settlements destroy trust.
The system must update markets and resolve predictions accurately. When a cricket match ends the app must know immediately. When a stock reaches a certain price the app must know immediately. Speed and accuracy matter equally.
5. UI and UX Design
Clear dashboards show active markets, odds, and user portfolio. Users should see at a glance what is available and how their predictions are performing. One tap prediction execution makes trading fast. Summaries of potential payouts show users what they can win before they commit.
Live ticker or feed showing the latest market movements creates excitement. Users see activity happening in real time. That activity encourages them to participate.
6. Backend and Scalability
Use microservices architecture for trading engine, user management, and data feeds. This separation allows each component to scale independently. Build robust databases and cache layers for fast access under high load. During major events millions of users might access the app simultaneously. The system must handle that load without crashing.
