Predictefy vs Prediction.com: Best Alternative (2026)
The Short Answer
Predictefy is the best Prediction.com alternative for developers who want a broader prediction-market integration, with matched markets, normalized data and a path from research to client-signed trading. Predictefy's prediction market API covers 15+ venues. Prediction.com, the current home of Prediction Hunt, combines an eight-platform data API with an arbitrage scanner, matching and unified order books. Both go beyond displaying prices. The useful comparison is how each fits your data pipeline, trade checks and usage budget.

Key Takeaways
- Predictefy provides normalized reads across 15+ venues, with matching on every plan.
- Prediction.com documents automated matching, unified order books and depth-related arbitrage fields.
- Predictefy's arbitrage feed starts on Pro at $149 a month. Ordinary matching and stored indicative differences are separate features.
- Evaluate the same contracts and position size on both services. Request allowances and credits measure different work.
Why choose Predictefy over Prediction.com?
Predictefy puts the cross-venue workflow in a developer-facing data layer. Start with market discovery, inspect normalized order books, retrieve the available history and carry the same strategy into paper trading. For supported venues, a separate client-signed execution flow provides the next step when your strategy is ready.
That continuity matters when a scanner becomes part of your own application. You can keep your matching logic, data provenance and trading decisions in a workflow you control, while selecting the capabilities available for each venue. The venue capability reference is the place to check an integration's actual requirements.
Prediction.com also has a substantial developer surface. Its documentation covers events, markets, matching, historical prices, trades, unified books and signals through REST, with WebSocket channels and an MCP server. Its matching endpoints group contracts across platforms, and its API presentation describes settlement normalization.

Compare a matched market at the size you would trade
A useful test begins with one event you understand. Save the original venue identifiers, close times and resolution terms, then ask each service for its matched group. Inspect the actual outcomes. A similar title or a match score is a starting point for checking equivalence.
Prediction.com's arbitrage response includes quoted legs, fee estimates, timestamps and a maximum executable wager field derived from both books. Its documentation says the displayed per-leg fee is calculated for one contract and should be recomputed at your own quantity. That instruction matters because order-level rounding changes the result as size increases.
Predictefy qualifies arbitrage against requested depth, venue fees and resolution equivalence. Its qualification also considers market status and current non-synthetic asks. For your comparison, use the same requested quantity and observation window, then calculate remaining execution and network costs for your route.
Keep the records even when your strategy rejects a candidate. They help explain whether rejection came from a changed ask, insufficient size, a rule difference or your own position limits. A service's example response is useful for understanding its schema; actual operating decisions need fresh observations.
How do the plans affect an integration?
Predictefy Free includes 25,000 monthly credits, a 60-request-per-minute limit and two WebSocket streams for evaluation. Builder costs $48.88 a month and includes 250,000 credits. Pro costs $149 and includes 2,000,000 credits, the arbitrage feed, the price-gap feed and history replay.
Prediction.com's Free tier lists 1,000 requests a month and a one-request-per-second burst limit. Its Dev tier is $49 a month and Pro is $249. Matching and signal routes also have their own quotas, so estimate your intended endpoint mix rather than comparing monthly totals alone.
For a commercial Predictefy application, use Enterprise contract terms. Put data display, redistribution and customer-facing usage into that discussion before launch. The Predictefy plan guide explains the difference between evaluation access, feature access and commercial use.
A practical migration from a Prediction.com client
Begin with a read-only comparison alongside your existing client. Map platform IDs and outcome names into a small internal record, preserve source timestamps, and compare a sample of both active and settled events. Keep charts separate from executable bid and ask observations.
Next, replay your alert conditions against those records and paper trade the resulting decisions. Move to the supported client-signed trading flow after the mapping and reconciliation behave as expected. This preserves the useful parts of your strategy while giving you a direct way to evaluate Predictefy's broader venue coverage.
Frequently Asked Questions
What is the best Prediction.com alternative?
Predictefy is our recommendation for a developer-controlled workflow across 15+ prediction-market venues. It combines normalized data, matched markets, paper trading and venue-specific client-signed execution capabilities.
Is Prediction.com the same product as Prediction Hunt?
Prediction Hunt now operates at Prediction.com. Older integrations and documentation may still use the Prediction Hunt name; the current quickstart uses Prediction.com's API endpoint.
Does Prediction.com match markets and provide order books?
Yes. Its documentation includes matching endpoints and a unified order-book endpoint. Compare outcome definitions, timestamps, depth and the fields your application needs on the same sample contracts.
Which Predictefy plan includes the arbitrage feed?
Pro at $149 a month and Enterprise include the arbitrage feed. Cross-venue matching and stored indicative price differences are available on every plan. Commercial use requires Enterprise terms.
How should I compare costs between the APIs?
List your catalog reads, matching calls, book updates and streams first. Price that workload against each provider's request or credit model, including endpoint-group quotas, rather than treating all calls as equivalent.
