Sports betting apps have become a major part of this expansion, offering users the ability to bet from anywhere at any time. These apps provide a seamless experience with real-time betting options, live streaming, and secure digital payments. Live betting, in particular, enhances engagement by allowing users to place wagers during live events and adjust their bets as the game progresses.
Top platforms like FanDuel, DraftKings, BetMGM, and Caesars have solidified their positions in the market by offering innovative features and forming strategic partnerships with major sports leagues like the NFL and NBA. These collaborations, along with data partnerships like those with Genius Sports, have helped these platforms build trust and maintain a strong, competitive edge in the growing industry.
What are Sports Betting Apps?
A sports betting app is a digital platform that allows users to place bets on sporting events through their mobile or web devices. These apps function as online bookmakers, providing odds, managing bets, and processing payouts, all while maintaining a secure and user-friendly environment for users.
Types of Bets Supported
| Type of Bet | Description | Example |
| Moneyline Bets | A simple wager on which team or player will win the game. | Betting $100 on the Lakers with +150 odds returns $250 ($150 profit + $100 stake). |
| Point Spread Betting | Betting on a team to win by a specific margin or lose within a certain margin. | Patriots -3.5 vs. Jets +3.5. |
| Parlays (Accumulators) | Combining multiple bets into one for a higher payout, but all must win. | A 3-team parlay at +600 odds. |
| Live/In-Play Betting | Wagering on events as they happen, with odds that change in real time. | Betting on the next goal scorer in a soccer match. |
| Prop Bets (Proposition Bets) | Wagers placed on specific events or occurrences within a game. | “Will LeBron James score over 25.5 points?” |
| Futures | Long-term bets on outcomes like championships or individual player awards. | “Chiefs to win the Super Bowl 2025 at +800.” |
| Over/Under (Totals) | Betting whether the combined score of two teams will be over or under a set number. | “NFL game total points over 48.5.” |
How Does the FanDuel App Work?
FanDuel has cemented its position as a top contender in U.S. sports betting by blending advanced technology, a sleek user experience, and sharp marketing tactics. This breakdown dives into the platform’s inner workings, exploring the features that make FanDuel stand out in an increasingly competitive market.
1. User Experience: Clean & Engaging Interface
At the core of FanDuel’s success is its user-friendly design that appeals to both casual and seasoned bettors alike.
- Simplified Bet Slip: Bettors can place wagers in a single click, with clear odds displayed for easy decision-making.
- Live Betting Hub: The platform offers real-time updates, ensuring odds and stats are always current.
- Quick Deposit/Withdrawal: With support for Apple Pay, PayPal, and instant bank transfers, users can quickly manage their funds.
- Dark Mode & Custom Themes: Designed for comfort, especially during long betting sessions.
Why It Works: Unlike many traditional sportsbooks, FanDuel’s layout is clean and accessible, allowing new users to easily navigate the platform and make informed bets without feeling overwhelmed.
2. Same Game Parlay
FanDuel revolutionized sports betting with the introduction of Same Game Parlays, giving users the ability to create custom bet combinations from a single game.
For example, you could bet on Patrick Mahomes throwing over 300 yards, Travis Kelce scoring a touchdown, and the Chiefs winning all in one parlay. It’s a fun way to increase your potential payout by combining different bets from the same game.
Impact:
- 30% of FanDuel’s bets now come from Same Game Parlays.
- This innovation drives higher engagement as users enjoy the challenge of building personalized, high-reward bets.
3. Cross-Product Integration
FanDuel seamlessly combines multiple gambling verticals into one cohesive platform, offering a broad range of betting options for users:
| Product | Key Feature |
| Sportsbook | Live betting, props, futures |
| Daily Fantasy (DFS) | Draft teams, win cash prizes |
| Online Casino | Slots, blackjack, live dealers |
| Horse Racing | Fixed-odds & pari-mutuel betting |
| FanDuel TV | Free sports content with betting integration |
Advantage: By offering all these products in one app, FanDuel ensures that users stay within its ecosystem, improving retention and encouraging cross-product engagement.
4. Fast Payouts & Trust-Building Mechanisms
Trust is key in betting, and FanDuel gets it right by offering quick and transparent payouts. Most withdrawals are processed within an hour, and you can choose from options like debit cards, PayPal, or Play+ prepaid cards. Plus, the payout limits are crystal clear, so there’s no confusion when it comes to withdrawing your winnings.
Result: FanDuel boasts one of the lowest complaint rates among U.S. sportsbooks, largely due to its fast and reliable payout process.
5. Aggressive Promotions & Gamified Engagement
FanDuel knows how to keep things exciting with great bonuses and promotions. You can score risk-free bets like “Bet $5, Get $150 in Bonus Bets,” or compete in leaderboard challenges for cash prizes. Plus, they offer odds boosts for select games and VIP rewards for the high rollers, so there’s always something to keep you coming back!
Outcome: These promotions create a dynamic and rewarding betting experience, leading to higher user engagement and loyalty.
6. Geolocation & Regulatory Compliance
FanDuel ensures that users only place bets in legally authorized regions, while preventing users from bypassing restrictions using VPNs.
- Multi-Layer Geo-Verification: Uses GPS, Wi-Fi, and IP triangulation to confirm user locations.
- KYC Checks: ID verification is mandatory before betting.
- Real-Time Compliance Alerts: Flags suspicious activity to ensure legal operations.
Result: FanDuel operates legally in over 18 states without any major compliance violations.
7. Player-Centric Personalization (AI/ML)
FanDuel takes personalization to the next level using AI and machine learning. By tracking your betting patterns and preferences, it suggests bets tailored just for you, even adjusting offers mid-game to keep things fresh. These personalized boosts have been shown to increase engagement by 25%, making the experience feel more dynamic and rewarding.
Benefits of Developing a Sports Betting App for Businesses
Developing a sports betting app opens up new revenue streams like in-app ads, commissions on bets, and premium memberships. It also boosts customer loyalty through personalized experiences and keeps users engaged with features like live betting.
Business Benefits
1. New Revenue Streams
Sports betting apps create diverse income channels, including commissions on bets (vig/juice), in-app advertising, premium memberships, and cross-selling opportunities with casino games or fantasy sports. For instance, DraftKings generated $2.24 billion in revenue in 2023, largely driven by its sportsbook and iGaming operations.
2. Increased Customer Loyalty & Retention
By offering a personalized betting experience, gamification elements like leaderboards, and live in-play betting, sports betting apps can significantly boost user retention. In fact, betting apps see three times higher retention rates compared to traditional gambling platforms, thanks to these engaging features.
3. Brand Expansion & Market Penetration
Developing a sports betting app allows businesses to tap into younger, tech-savvy demographics and expand into new geographic markets as sports betting becomes legal in more regions. For example, ESPN’s partnership with Penn Entertainment to launch ESPN Bet illustrates how media brands are entering the market to leverage their existing audience.
Technical Advantages
1. Scalable Cloud Architecture
Modern betting apps are built using scalable cloud infrastructure that handles traffic spikes, especially during major events. Features like microservices, serverless computing, and edge computing ensure seamless user experiences. FanDuel’s infrastructure, powered by AWS, supports over a million concurrent bets during events like the Super Bowl.
2. Data-Driven Personalization
Sports betting apps can leverage AI-driven odds optimization and predictive analytics to personalize users’ experiences. By analyzing betting patterns and user history, apps recommend tailored bets, ensuring users receive real-time notifications for favorable odds. Technologies like machine learning models (e.g., TensorFlow) and Apache Kafka for real-time data enhance these capabilities.
3. Secure & Fast Payment Processing
To ensure fast and secure transactions, sports betting apps use multi-layer encryption (PCI-DSS compliance) and blockchain for provably fair bets. Additionally, instant payouts via digital wallets and Open Banking APIs enhance the user experience. BetMGM, for example, processes $500M+ in monthly transactions with 99.99% uptime.
How to Develop a Sports Betting App Like FanDuel?
When developing a sports betting app, we follow a clear step-by-step process to ensure that the app meets both user needs and regulatory requirements while offering a high-quality experience.
1. Research Legal Markets
The first step in creating a sports betting app is to thoroughly research the legal landscape. We analyze the regulations, licensing requirements, and compliance standards like KYC/AML in the target jurisdictions. This ensures that your app adheres to the necessary legal frameworks and can operate smoothly across different regions.
2. Build Core Backend
To support real-time data and ensure a smooth betting experience, we develop a secure and scalable backend architecture using microservices. This allows for flexibility, easy scaling, and resilience, ensuring that your app can handle high traffic during major events while maintaining performance and security.
3. Create Engaging Frontend
The frontend of your app is designed with a focus on cross-platform compatibility, ensuring a seamless experience on both iOS and Android. We create a user-friendly, intuitive UI/UX, allowing users to easily navigate the betting platform. Engaging design elements and smooth interactions help enhance user retention and satisfaction.
4. Integrate Real-Time Sports Data
For an effective sports betting app, integrating live data is crucial. We connect the app to sports APIs that provide real-time scores, odds, and player stats, ensuring that users always have access to up-to-date information for making informed bets. This feature keeps the experience dynamic and engaging.
5. Add Payment Systems
A seamless payment system is essential for any betting platform. We integrate secure payment gateways, supporting traditional payment methods as well as cryptocurrencies for added flexibility. Fast withdrawal options and a smooth deposit process ensure that users can easily manage their funds without delays or issues.
6. Personalize User Experience
To enhance user engagement and retention, we integrate AI-driven recommendations and personalized content. Loyalty programs and social features create a community-driven experience, motivating users to return to the app. Tailoring the app’s offerings to individual preferences fosters a more engaging and dynamic betting environment.
Key Challenges to Developing a Sports Betting App
Having worked with numerous clients on sports betting apps, we understand the challenges that often arise during development and how to tackle them. Here’s a look at the most common hurdles and effective solutions.
1. Regulatory Fragmentation
Sports betting laws differ significantly across countries, states, and even sports leagues. For instance, New Jersey allows online betting, while Utah bans it altogether, and some leagues restrict certain types of bets, like prop bets. An example is a bettor in New York who can wager on the NFL but not college games played within the state.
The Solution
To address this, we partner with gambling compliance firms like GLI and eCOGRA to ensure full legal adherence. Multi-layered geofencing (GPS, IP, Wi-Fi triangulation) helps restrict access based on location, while adaptive rule engines adjust betting markets in real-time depending on the jurisdiction.
Pro Tip: FanDuel uses GeoComply to prevent cross-border betting fraud.
2. Data Latency in Live Betting
Live betting relies on real-time data, requiring sub-second updates during games, synchronized across millions of devices, with no discrepancies between the backend and user interface. Even a slight delay can cause significant losses—just 10 milliseconds can result in costly arbitrage errors.
The Solution
We use WebSockets and Server-Sent Events (SSE) for faster data transfer than traditional REST APIs. Edge computing, through providers like Cloudflare and AWS Lambda@Edge, ensures that data is processed closer to users, minimizing latency. Direct integrations with data providers like Sportradar and Genius Sports help further optimize live data feeds.
Tech Stack Used by Bet365: Kafka (real-time data streaming), Redis (in-memory caching).
3. Security Risks & Fraud Prevention
Security remains a major concern, as sports betting apps are vulnerable to account takeovers (ATO), bonus abuse, and money laundering. In fact, 30% of betting fraud is attributed to bonus exploitation, where users exploit free bets across multiple accounts.
The Solution
We implement multi-factor authentication (MFA), combining SMS and biometrics for added security. AI-powered fraud detection helps track suspicious patterns, such as bettors who always win or make abnormal betting activity. Additionally, blockchain auditing ensures an immutable transaction log for transparency and fraud prevention.
Example: DraftKings uses Sift’s machine learning to detect arbitrage bettors.
4. Scalability During Peak Traffic
High-traffic events like the Super Bowl lead to a 10X surge in user activity, with a spike in concurrent bets and significant server load risks. FanDuel, for example, handles over 1 million bets per minute during March Madness.
The Solution
To handle these massive surges, we use a microservices architecture that isolates critical functions like payments and odds engines. Cloud auto-scaling with AWS EC2 and Kubernetes allows us to dynamically allocate resources based on traffic. Load testing simulates traffic from hundreds of thousands of users before launch to ensure a smooth user experience.
Essential Tools & APIs for Building a Sports Betting App
Creating a sports betting app like FanDuel requires a robust technology stack to ensure high performance, security, and scalability. Below are the essential tools, APIs, and frameworks that will help you build a seamless, cutting-edge sports betting platform.
1. Sports Data APIs (Real-Time Odds & Stats)

| OddsAPI | Affordable option for startups |
Why It Matters:
- Live odds updates are crucial for in-play betting.

Integration Tip: For real-time data streaming, use WebSockets instead of REST APIs to reduce latency and improve performance.
2. Payment Gateways (Deposits & Withdrawals)
Payment processing is a key part of any betting platform. You need a secure and fast system for deposits and withdrawals. The best solutions include:
| Provider | Supported Methods |
| Stripe | Credit/debit cards, Apple Pay, Google Pay |

| Skrill | Popular in Europe, low fees |
| Coinbase Commerce | Bitcoin, Ethereum, crypto payments |
Key Considerations:

Pro Tip: Use tokenization (e.g., Stripe, Braintree) to securely store payment details and enhance data security.
3. Geolocation & Compliance Services
Ensuring that users can only place bets in legally approved regions is essential for compliance. Key tools for geolocation and user verification include:
| Service | Use Case |
| GeoComply | U.S. geofencing, fraud prevention |

| Jumio | KYC/AML identity verification |
Why It’s Critical:

4. Cloud Hosting & Scalability
A reliable cloud platform is essential for scalability, especially during peak traffic. Here are the best options:
| Provider | Best For |
| AWS | Auto-scaling, global reach |

| Microsoft Azure | Enterprise hybrid deployments |
Key Services Needed:
- EC2 (AWS) / Compute Engine (GCP) for virtual servers.
- Lambda / Cloud Functions for serverless processing.
- Kubernetes for container orchestration in microservices.
Example: FanDuel uses AWS to handle over 1 million concurrent users during major events like the Super Bowl.
5. AI/ML Tools (Personalization & Fraud Detection)
AI and machine learning are vital for personalizing the user experience and detecting fraud. Recommended tools include:
| Tool | Application |
| TensorFlow/PyTorch | Custom odds models, churn prediction |
| AWS SageMaker | Pre-built ML for betting patterns |
| Sift/Fraud.net | Detect bonus abuse and money laundering |
Use Cases:
- Dynamic Odds Adjustment: React to changing betting volumes.
- Personalized Promotions: E.g., “You usually bet on NBA—here’s a Celtics boost!”
6. Security & Compliance Tech
Security is a top priority in sports betting. Essential tools and solutions include:
| Tool | Purpose |
| Auth0/Okta | Secure login & multi-factor authentication (MFA) |
| Elliptic | Crypto transaction monitoring |
| Smart Contracts (Ethereum/Solana) | Transparent, tamper-proof payouts |
Critical Measures:
- End-to-End Encryption (TLS 1.3) to protect user data.
- Regular Penetration Testing to identify and fix vulnerabilities.
Use Case: Enhancing a Gaming Platform with Sports Betting
Our client, a fast-growing fantasy sports platform with over 500,000 active users, wanted to expand into real-money sports betting without disrupting their existing ecosystem. They needed seamless integration, live betting features, and regulatory compliance for a state-by-state U.S. rollout, all while offering a unified wallet for both fantasy entries and sports bets. We successfully delivered these solutions, enhancing their platform’s user engagement and revenue.
Our Solution: A Hybrid Sports Betting Integration
We integrated real-time odds and live betting features alongside the existing fantasy contests, creating a unified wallet system for both fantasy entries and sports bets. This ensured seamless user experience while maintaining regulatory compliance across multiple states.
Live Odds Feed Integration
We used the Sportradar API to integrate real-time pre-match and in-play odds for major leagues like NFL, NBA, and MLB. The “Bet Now” feature during live fantasy contests allowed users to place bets on the spot, keeping them engaged. This led to a 35% boost in session duration, as users stayed active throughout the events.
Unified Wallet System
We used Stripe Connect for fiat transactions and Fireblocks for crypto deposits, creating a unified wallet for both fantasy entry fees and sports betting. This allowed for instant withdrawals via PayPal and streamlined the user experience. As a result, we saw a 50% increase in deposit volume, making it easier for users to manage all their funds in one place.
Geolocation Compliance Engine
We used GeoComply for real-time location checks to ensure users were in legal betting states and Jumio for KYC/AML verification. This helped us enforce state-specific rules, like banning college prop bets in New York, while also detecting VPN or spoofing attempts. The result was zero regulatory violations across 12+ states where the platform operates.

| Odds Display | React.js + WebSockets | Real-time updates without page refresh |
| Bet Processing | Node.js microservices | Handle 10K+ bets per minute at peak |
