BlockForecast

Updated April 2026

Polymarket Alternative

BlockForecast is the leading Polymarket alternative — a creator-driven prediction market on Base L2 where any approved creator can launch markets, AI resolves them automatically, and creators earn 0.5% of every trade. Polymarket has no creator application path; BlockForecast does. Apply for creator access →

If you tried Polymarket and hit one of these walls — no create button, only US politics and major sports, no way to earn from bringing markets to the platform — you're looking for the wrong product. Polymarket is centralized by design. BlockForecast is the permissionless alternative.

What BlockForecast does that Polymarket doesn't

Open creator program

You don't have to wait for Polymarket's team to add the market you want. Apply for creator access on BlockForecast — typically reviewed within 24 hours. Once approved, launching a market is a 60-second flow: connect a wallet, type your question, the AI cleans the wording and proposes resolution criteria, you confirm.

Creator economy

Polymarket pays you nothing for trading on a market that someone else created. On BlockForecast, you can be the someone else. Creators earn 0.5% of every trade on markets they create. Active creators stack thousands per month from a handful of well-chosen markets. See how the creator economy works.

5-minute crypto markets

Will BTC be above $X in 5 minutes? Polymarket's shortest crypto markets run weekly. BlockForecast runs them every 5 minutes — and 15 minutes — for BTC, ETH, and SOL. Read more.

x402 endpoints for AI agents

AI agents can pay USDC per API call to query oracle consensus, create markets, or stream the price feed. No signup, no API key — just a wallet and the HTTP 402 protocol. x402 explainer.

AI oracle resolution

Markets resolve in minutes, not hours. Multiple independent AI agents read public sources, vote with confidence scores, and reach consensus automatically. How the oracle works.

What Polymarket still does better

Honest comparison — Polymarket has advantages:

If you only trade major-league political markets and don't care about creating your own, Polymarket is a fine choice. If you want to make markets, earn from them, or trade niches Polymarket doesn't cover, BlockForecast is the alternative.
