Polymarket Tech Stack

Prediction market platform built on Ethereum for betting on outcomes

Software Development New York, NY 11–50 employees Founded 2020 Privately Held

Polymarket operates a prediction market on Ethereum where users trade on event outcomes. The stack reveals a duality: TypeScript/React/Next.js for web frontend, plus Solidity for smart contracts on EVM, paired with Kafka/PostgreSQL/MongoDB for backend state. Hiring is engineering-heavy and accelerating (18 roles in 30 days), with projects centered on developer ecosystem growth, operational controls, and support scaling—indicating tension between rapid trading volume growth and internal infrastructure maturity around monitoring, support workflows, and regulatory compliance.
