Polypump – Predictive Markets Platform

Overview

Polypump is a predictive markets platform built on Solana within the pump.fun crypto-meme ecosystem. It allows users to create and participate in prediction markets on meme coins and tokens launched on pump.fun. Polypump supports both SOL (Solana’s native coin) and $POLYPUMP (the platform’s utility token) for betting. The platform is designed with a deflationary reward model: a portion of every market’s payouts is burned (reducing $POLYPUMP supply) and a portion is allocated as developer rewards. This mechanism incentivizes participation while maintaining token scarcity and funding ongoing development.

In this example, users can bet on whether more than 500 "shitcoins" will migrate today. The interface shows a Yes/No question with dynamic odds (Yes at $0.75, No at $0.25), indicating implied probabilities based on current bets. Users can choose their stake (paid in $POLYPUMP here) and side before confirming the bet.

Polypump’s architecture is technical and on-chain: markets are created via smart contracts that track bets and outcomes. Each prediction market is associated with a specific token (identified by its Solana token address) and a condition to be evaluated (for example, a target market capitalization or an event like a token migration). Participants connect their Solana wallets to place bets on the outcome (typically a Yes/No outcome for a given question). Once the market reaches its conclusion (the pre-set end time or event trigger), the outcome is determined automatically by checking on-chain data or oracle feeds for the condition. Winners are paid out trustlessly by the smart contract, while the built-in burn and developer fee mechanisms redistribute a fraction of the pot to bolster the token’s value and support the project’s development.
