What is PredictionHunt?

Prediction markets have exploded in popularity. From presidential elections and geopolitical events to crypto prices and pop culture, platforms like Polymarket, Kalshi, and PredictIt have become the go-to venues for forecasting the future. However, this ecosystem is deeply fragmented. Each platform operates with its own order books, liquidity pools, fee structures, and, critically, varying odds for the exact same underlying event.

Enter PredictionHunt, the Bloomberg Terminal for prediction markets.

PredictionHunt is an advanced analytics platform and developer tool that aggregates data from every major prediction market. It pulls live odds, order book snapshots, and trading volume into a single, unified interface and API. By normalizing this chaotic data, PredictionHunt empowers traders to instantly compare prices across platforms, unearthing inefficiencies that are impossible to spot manually.

At its core, PredictionHunt serves two distinct audiences:

1. The Discretionary Trader: Through its intuitive web dashboard, retail traders can browse trending markets, view real-time cross-platform odds comparisons, and receive live alerts for arbitrage opportunities and “Smart Money” movements.
2. The Algorithmic Developer: Through its robust API infrastructure (REST and WebSockets) and its innovative MCP server for Claude and Cursor, PredictionHunt allows developers to build high-frequency trading bots, automated arbitrage scanners, and custom AI trading terminals.

Whether you are trying to find a 2% arbitrage between Kalshi and Polymarket on the outcome of an election, or you want to track the wallet of a historically profitable “whale” to mirror their trades, PredictionHunt is the definitive software stack for prediction market dominance.

Who Should Use PredictionHunt? (Use Cases & Why Choose It)

PredictionHunt is not a traditional sports betting tool like OddsJam; it is purpose-built for the unique mechanics of event-driven prediction contracts. You should choose PredictionHunt if you fit into one of the following profiles:

1. The Cross-Platform Arbitrageur

If you understand the math of arbitrage—locking in a risk-free profit by betting on all possible outcomes across different exchanges—PredictionHunt is mandatory. Because Polymarket (crypto-native) and Kalshi (fiat-native US regulated) serve entirely different demographics, their odds frequently diverge. PredictionHunt’s Arbitrage Scanner constantly scours these discrepancies. If Donald Trump is trading at 55¢ on Polymarket and 45¢ on Kalshi, an arbitrageur can buy “Yes” on both sides, guaranteeing a profit. PredictionHunt calculates the exact sizing and execution parameters for you.

2. The Algorithmic Quantitative Developer

Building integrations for five different prediction markets is a nightmare. Each has different API limits, data schemas, and WebSocket architectures. PredictionHunt abstracts all of this away. With a single API call (GET /api/v2/search), you can pull normalized odds from every platform simultaneously. Furthermore, PredictionHunt offers an MCP (Model Context Protocol) Server, allowing AI assistants like Claude and Cursor to directly interact with prediction market data. If you are building a trading bot, the $49/mo Dev plan saves hundreds of hours of infrastructure engineering.

3. The “Smart Money” Tracker (Copy Trader)

In prediction markets, especially on transparent blockchains like Polymarket (Polygon), wallet addresses are public. PredictionHunt’s Smart Money feature tracks accounts that have historically demonstrated high ROI. By scanning for whale activity and high-volume trades from these “sharp” accounts, you can mirror the positions of insiders and professional syndicates before the broader market reacts.

4. The Political & News Junkie

If you actively trade elections, geopolitical outcomes, or macroeconomic data (like CPI prints or Fed rate cuts), PredictionHunt is your command center. The Trending section highlights markets experiencing rapid volatility or surging volume, ensuring you never miss an opportunity when breaking news hits the wire.

5. The Beginner (Via Paper Trading)

Prediction markets operate differently than traditional sportsbooks (they use an order book model with limit/market orders, rather than fixed odds). PredictionHunt’s Paper Trading feature allows you to simulate trades with a virtual portfolio using real-time data. It is the perfect sandbox to test your strategies before risking actual capital.

Deep Dive: Core Features and Trading Functions

PredictionHunt is defined by its five core pillars: Smart Money, Arbitrage, Trending, Paper Trading, and its API ecosystem. Let’s break down how each works and how to extract maximum value from them.

1. Smart Money Feed: Tracking the Whales

The Smart Money feed is arguably PredictionHunt’s most unique feature. Prediction markets are often driven by asymmetric information—someone knows something before the public does.

PredictionHunt algorithms constantly monitor the blockchain and exchange data to identify “historically profitable accounts.” When these accounts make significant, high-volume trades, the Smart Money feed instantly alerts you.

How to use it:

• Monitor the Feed: Keep the Smart Money dashboard open during major events. When you see a sudden influx of $50,000+ buys on a specific outcome (e.g., “Will OpenAI release GPT-5 by December?”), it strongly indicates insider knowledge or a sharp syndicate taking a position.
• Fade the Public: Often, the public reacts emotionally to news, while the Smart Money acts rationally. The feed helps you identify when sharp bettors are taking the opposing side of a popular narrative.
• WebSocket Integration: On the Pro plan, you can subscribe to the Smart Money WebSocket channel to algorithmically execute trades the millisecond a tracked whale wallet initiates a position.

2. Arbitrage Scanner: Finding Risk-Free Profit

Arbitrage is the holy grail of trading. The Arbitrage Scanner compares identical markets across Polymarket, Kalshi, PredictIt, and ProphetX to find pricing inefficiencies.

What Works & Crucial Caveats:

• Speed is Everything: Arbs in highly liquid markets close quickly. A 3% discrepancy between Kalshi and Polymarket might only last 15 seconds. This is why PredictionHunt is essential; human eyes cannot scan fast enough.
• The Resolution Trap: PredictionHunt explicitly warns: “Always double-check resolution criteria and betting rules before placing a trade.” This is critical. Polymarket might resolve a political question based on Associated Press calls, while Kalshi might require official congressional certification. If the criteria differ slightly, it is not a true arbitrage—it is a correlation trade with risk. PredictionHunt links the markets, but you must read the fine print.
• Execution Strategy: Keep funded accounts on all supported platforms. When the scanner flags an arb, use limit orders to ensure you get the exact price displayed. PredictionHunt’s matching engine handles the math, telling you exactly how many shares to buy on each side to guarantee the return.

3. Trending Markets: Capitalizing on Volatility

The Trending dashboard is your heat map for the prediction ecosystem. It aggregates data to show which markets are experiencing the highest velocity of trades, the largest percentage price swings, or the highest overall volume across all platforms.

How to use it:

• Discover Unknown Events: You might be focused on the US Presidential Election, completely missing that an obscure FDA approval market is seeing massive volume spikes. The Trending page acts as an alert system for breaking news.
• Liquidity Hunting: For traders with larger bankrolls, the Trending page highlights where the liquidity is concentrated, ensuring you don’t get trapped in a low-volume market with wide bid/ask spreads.

4. Paper Trading: The Ultimate Sandbox

PredictionHunt’s Paper Trading suite is a fully-featured simulation environment. It uses real-time, live data from the exchanges but allows you to execute trades with “fake” money.

Use Cases:

• Strategy Backtesting: Have a theory that fading early polling data is profitable? Test it over a month in the Paper Trading environment before deploying real fiat/crypto.
• Learning Order Books: If you are used to the fixed-odds model of DraftKings, the bid/ask spread and order book mechanics of Kalshi and Polymarket can be confusing. Paper Trading teaches you the difference between crossing the spread (market orders) and providing liquidity (limit orders) without financial risk.

5. The Developer API & MCP Server

For institutions, quantitative traders, and AI developers, PredictionHunt’s API is the star of the show. Instead of managing OAuth, WebSocket connections, and disparate JSON schemas for five different exchanges, developers use PredictionHunt as a single source of truth.

Core Endpoints:

• Events · Markets · Search: Find any market via keyword across all platforms.
• Cross-platform matching: Programmatically find identical markets.
• Prices & price history: Pull historical data to train machine learning models.
• Orderbook snapshots: Get deep liquidity metrics.

The MCP Server (Claude/Cursor Integration): PredictionHunt includes an MCP (Model Context Protocol) server. This means you can hook PredictionHunt directly into your AI coding environment (like Cursor) or chatbots (like Claude). You can literally type: “Claude, analyze the current arbitrage opportunities between Polymarket and Kalshi for the 2026 Midterms and write a Python script to execute the trades.” The MCP server provides the AI with live data, dramatically accelerating AI-driven algorithmic trading.

Step-by-Step Setup: Getting Started with PredictionHunt

Ready to extract value from the prediction markets? Follow this optimal path to get started.

Step 1: Secure Your Exchange Accounts

PredictionHunt is an analytics engine, not an exchange. To execute the trades it finds, you must have funded accounts.

1. Polymarket: Connect a crypto wallet (like MetaMask or Phantom) and fund it with USDC on the Polygon network.
2. Kalshi: Create an account, verify your identity (US only), and fund it via ACH or wire transfer.
3. PredictIt / ProphetX: Create and fund these accounts to maximize your arbitrage surface area.

Step 2: Sign Up and Explore the Dashboard (Free Tier)

Navigate to Prediction Hunt’s Web App and create a free account.

• Spend your first 48 hours purely observing.
• Click on the Trending tab to see how breaking news impacts prices.
• Open the Smart Money feed and watch how large wallets react to political polling data or crypto price movements.

Step 3: Utilize Paper Trading

Before risking a single dollar, navigate to the Paper Trading portfolio.

• Identify an arbitrage opportunity on the dashboard.
• Execute the trade in the Paper Trading simulator.
• Wait for the event to resolve to ensure you understand how the mechanics, fees, and order book slippage work.

Step 4: Upgrade and Automate (Dev/Pro Plan)

Once you are comfortable with the mechanics, it’s time to leverage the API.

• Upgrade to the Dev ($49/mo) or Pro ($249/mo) plan to unlock WebSockets and higher rate limits.
• Generate your API key in the developer dashboard.
• If you use Claude or Cursor: Install the PredictionHunt MCP server. This allows your AI to directly query the API and help you write your trading scripts in Python or Node.js.
• Build a simple script that queries GET /api/v2/search for a specific keyword (e.g., “Interest Rates”) and logs the cross-platform odds.

Step 5: Execute the Arbitrage Workflow

When your script (or the web dashboard) flags an arbitrage:

1. Verify the resolution criteria on both platforms immediately.
2. Check the liquidity (Orderbook depth) to ensure your desired stake size can be filled without severe slippage.
3. Execute the “buy” orders on both platforms simultaneously.
4. Hold until resolution, collecting the guaranteed risk-free profit.

Technical Reference: Rate Limits & API Architecture

For developers, understanding PredictionHunt’s architecture is crucial for maintaining uptime.

• Rate Limits & 429 Handling: The API enforces burst limits and monthly quotas. If you exceed your limit, the API returns a 429 Too Many Requests status. PredictionHunt strictly adheres to Retry-After headers. Your bots must implement exponential backoff to handle these grace periods without getting temporarily IP-banned.
• WebSocket Inbound Throttle: Across all paid plans, inbound messages are throttled to 10/sec to maintain server stability.
• SDKs and Quickstarts: PredictionHunt provides extensive code samples. You can theoretically make your first API call in under 2 minutes.

PredictionHunt vs. The Competition

While tools like OddsJam, BetBurger, and Outplayed dominate traditional sports betting, the prediction market aggregator space is much newer and far less crowded.

PredictionHunt is currently the undisputed leader in this specific niche.

• Traditional Odds Scanners (OddsJam) vs. PredictionHunt: OddsJam is incredible for DraftKings and FanDuel, but it does not interface with Polymarket or Kalshi order books. If you trade events, PredictionHunt is the only viable option.
• Building In-House: A developer might think, “I’ll just connect to the Kalshi and Polymarket APIs myself.” While possible, maintaining WebSocket connections, handling distinct API rate limits, normalizing completely different JSON structures, and building a cross-platform matching engine will take hundreds of developer hours. The $49/month Dev plan is vastly cheaper than the opportunity cost of building this infrastructure from scratch.

Our Verdict: Is PredictionHunt Worth It?

Prediction markets are the fastest-growing sector in finance and betting. However, because the ecosystem is immature, the pricing inefficiencies (arbitrage and +EV opportunities) are massive compared to highly efficient traditional sportsbooks.

PredictionHunt provides the shovel for this gold rush.

For the casual user, the Free tier and intuitive web dashboard provide a fantastic way to browse odds and track whales without spending a dime.

For the serious trader and developer, the value proposition of the Dev ($49/mo) and Pro ($249/mo) plans is exceptional. The ability to pull unified odds, track smart money via WebSockets, and utilize the MCP server for AI-assisted coding gives users an institutional-grade toolkit at a retail price.

What Works Best: The Arbitrage Scanner is the most immediate way to ROI your subscription, provided you have the bankroll and the accounts set up to execute quickly. Furthermore, the MCP integration is a game-changer for developers who want to rapidly prototype trading algorithms using Claude or Cursor.

Final Thought: If you are actively trading on Polymarket, Kalshi, or PredictIt and you are not using an aggregator like PredictionHunt, you are trading blind. You are missing cross-platform arbs, and you are flying without the radar that the Smart Money feed provides. Start with the free tier, run some Paper Trades, and watch how quickly the platform proves its worth.
