BroadChain News, Polymarket, a prediction market platform, is reportedly planning a migration from Polygon, sparking competition among multiple public chains. Josh Stevens, Polymarket's new Vice President of DeFi Engineering, publicly stated on April 25 that the platform's business growth has far exceeded the capacity of its existing infrastructure, and the team is advancing a series of technical upgrades to address pain points in high-frequency trading. Among these, the most market-focused solution is "chain migration." Stevens pointed out that the platform requires larger block space, lower gas fees, and shorter block times to achieve instant settlement.
Polymarket initially chose Polygon due to its low transaction fees, relatively fast settlement speeds, and mature EVM ecosystem. However, as platform trading volumes continue to rise, especially with a surge in high-frequency trading demand, issues such as increased transaction latency, poor order cancellation experiences, and reduced execution efficiency during network congestion have gradually emerged. Previous analysis indicated that attackers exploit the time gap between Polymarket's off-chain matching and on-chain settlement to repeatedly cause transaction failures at minimal cost, thereby clearing market maker orders and arbitraging. A single address could earn tens of thousands of dollars daily, with attack costs nearly zero. This mechanism flaw directly forces market makers and automated trading bots to face forced order cancellations, passive exposure of positions, or even direct losses, with no official solution currently available.
This is not the first time Polymarket has been rumored to migrate. Late last year, community discussions suggested the team planned to launch its own L2 server and gradually move away from Polygon. Now, Stevens' public statement is seen by outsiders as the plan moving from internal discussions to the implementation phase. Following the announcement, public chains such as Sui, Solana, Sonic, Algorand, and Sei have extended olive branches to Polymarket, citing reasons including lower fees, faster transaction confirmation times, high throughput, and friendly support for transaction-intensive applications.
For Polygon, Polymarket's migration would result in significant revenue losses at the ecosystem level. Dune data shows that Polymarket currently contributes approximately 56.3% of Polygon's transaction fees. Based on the latest daily fee structure, for every $100 in fees generated by Polygon, about $56 comes from Polymarket. So far this year, Polymarket has contributed approximately $72.9 million in transaction fees, accounting for 61.3% of Polygon's total transaction fee revenue (about $119 million). Polymarket has become Polygon's core economic engine, and if its migration plan is implemented, it would directly lead to a substantial decline in Polygon's revenue.
