Predictefy Overview
Predictefy is a data and trading terminal built for people who trade on prediction markets. It does not run its own markets or contracts. Instead, it pulls live prices, liquidity, order books, and volume from platforms like Polymarket, Kalshi, Hyperliquid, Limitless, and others, then lines them up in one screen. You get one place to check odds, compare markets, and place trades instead of ten browser tabs.
This tool is for traders who already split their capital across more than one platform. If you only ever use Polymarket and never check prices anywhere else, Predictefy will not change much for you. But if you want the best price on an election, sports, or crypto market and hate manually comparing spreads, this is built for that exact job. Market makers use it to spot cross-venue gaps. Developers use it to build bots and trading agents on top of the same feed through the API, SDK, and MCP server.
The core of Predictefy is market matching. It finds the same event listed across different platforms and shows side-by-side prices, implied probability, and available size. A live arbitrage feed flags price gaps between matched markets and shows if the spread is big enough to cover fees. When you find a trade you like, you place the order right inside Predictefy, and the system routes it to whichever venue has the better price and depth. For Kalshi trades, you connect your own API key, and the signing happens in your browser, so the platform never holds your credentials. A portfolio view then tracks your open positions and balances across every connected venue in one dashboard.
What sets Predictefy apart is the mix of live routing and historical depth. Most terminals give you a live feed or historical data, not both. Predictefy has multi-year OHLCV data going back to 2020 for research and backtesting, alongside the live arbitrage tools for active trading. It charges no platform fees of its own, so you only pay what the destination venue charges. Add in the developer tooling for building agents and bots, and it works as much as market infrastructure as it does a trading app.
Predictefy Key features
-
Cross Venue Market Comparison
Predictefy matches the same event across different platforms and shows prices, probabilities, and liquidity side by side. Traders no longer need to check odds format by format on each site.
-
Real Time Arbitrage Detection
A live feed tracks price gaps between matched markets and shows the spread size and liquidity on each side. Traders can quickly check if a gap covers fees and slippage before acting.
-
Unified Trading and Routing
Users place orders directly inside Predictefy, and the system routes each order to the venue with the better price and liquidity. Kalshi orders use a locally signed API key and RSA key, so Predictefy never holds private keys.
-
Market Analytics Dashboards
Dashboards show 24 hour volume, trending contracts, and top movers across venues. Users can filter by category or volume to find opportunities faster than browsing each platform alone.
-
Historical OHLCV Data
Predictefy stores multi year open, high, low, close, and volume data for research and back testing. Traders can test a strategy before they risk real capital.
-
Unified Portfolio View
Balances, open orders, and positions from every connected venue appear on one screen. This helps traders avoid missing an open position when their capital sits across multiple platforms.
-
Developer SDK and MCP Server
Developers install the SDK through npm and use the MCP server to let AI agents query markets, spot arbitrage, and place orders under set limits. Full API access is currently open through private beta.
-
Customizable Trade Layout
Traders can rearrange trade panels, order books, and data columns to match their own workflow. Each user sets up the interface the way they actually trade.
Predictefy Fees
-
Platform trading fee Predictefy charges zero platform fees on trades executed across its supported venues.
-
Destination venue fees Users still pay each venue's own fees, such as Polymarket's category dependent taker fees or Kalshi's contract based schedule.
-
Gas costs Gas can be sponsored on several connected venues, so end users pay zero gas on those routes.
-
Subscription cost No subscription fee is currently required for the core trading interface, though advanced API access may involve waitlist or enterprise arrangements.

Predictefy Review
Our verdict
Predictefy earns its place for one clear reason: it fixes the pain of trading prediction markets across many platforms at once. Instead of juggling tabs between Polymarket, Kalshi, Hyperliquid, and others, you get one screen with matched prices, live arbitrage gaps, and order routing that stays non custodial since your keys never leave your browser. The zero platform fee policy and the SDK/MCP tools for developers add real weight, and the historical OHLCV data going back to 2020 makes it useful for research too. It falls short in a few places: the team is small, full API access sits behind a waitlist, and there is no mobile app yet, so bugs and slow support are fair trade-offs for an early product. If you already split capital across two or more venues, or you build trading bots and need clean normalized feeds, Predictefy saves real time and effort. If you only trade on one platform and never compare prices, you will not get much from it.
Is Predictefy safe & legit?
Predictefy is built by a small, bootstrapped team led by co-founder Tafcir Majumder, who has past work at Token Metrics, Genzio, and Betu. It has earned some trust in the space through a grant from Superteam Malaysia and data mentions in Business Insider and Messari Solana reports. The tool is non-custodial, meaning your private keys and API credentials never leave your device, and no major red flags exist beyond the usual caution of using a newer platform, so start with small amounts and double check the site URL before you log in.

Some of the prediction market bots we’ve been building using our API/SDK are unreal
- Arbitrage bots operating across 14 venues
- Market-making bots with advanced parameters
- Backtesting tools that let us test strategies before deploying capital
- Live sports and esports arbitrage bots
We’ve said this before, but we genuinely believe the next billion traders will be agents, not humans, and everything we’re building continues to strengthen that conviction
We’ve already laid the groundwork, built the infrastructure and tested these bots internally
Now we’re starting to deploy real capital
Backtested results are one thing, but the next step is proving these strategies in live markets
