@devjoshstevens @Polymarket Sui is the only chain that makes sense. - no block space - parallelized sequencing of all independent market transactions - 400ms finality, no reorgs - extremely cheap, especially since RGP was reduced by 80% - battle tested fully onchain CLOB as living proof Josh, let’s chat

@devjoshstevens @Polymarket Respect for the transparency. You’re hitting on challenges we’ve seen businesses at your scale run into when real-world traffic meets the blockchain. Our team has been heads-down with leaders across the space on how an L1 can fine-tune the execution environment around what

Steady attention without excessive speculation.
Josh Stevens, VP of Engineering (DeFi) at Polymarket, posted a detailed public thread on X on April 24. He outlined the platform’s infrastructure challenges and explicitly listed “chain migration” as a priority on their engineering roadmap.
Stevens joined the company just weeks earlier. Still, his thread marks the first official acknowledgment that Polymarket’s current home on Polygon cannot sustain its growth trajectory.
Polymarket’s volume has strained Polygon’s infrastructure significantly. As a result, Stevens highlighted several pain points in his thread. These include insufficient block space, higher gas fees, slow block times, and unexpected transaction cancellations during peaks.
The platform now accounts for $2.5M to $4M in weekly fee revenue on Polygon. Because of this dominance, Polymarket represents 50 to 70% of Polygon’s total transaction fee revenue. It also occupies multiple spots among Polygon’s top gas-consuming contracts.
Stevens stated the goal clearly: “more block space, cheaper gas and much smaller block times so settlement is instant.”
Polymarket runs entirely on Polygon mainnet (Chain ID 137). According to official documentation, all contracts, trading, and collateral live there since launch.
Meanwhile, a separate upgrade called CLOB V2 goes live on April 28 at approximately 11:00 UTC. This upgrade introduces new contracts, a rewritten backend, and pUSD as the new collateral token. The team expects roughly one hour of downtime.
The V2 upgrade happens on Polygon. So it is separate from the chain migration, which targets longer-term scalability.
This is not the first time Polymarket signaled intent to leave Polygon. In December 2025, the team prioritized building its own Ethereum L2 called “POLY” after earlier network outages disrupted trading.
At the time, the custom L2 served as a top priority. The goal was full control over infrastructure without relying on third-party chain performance.
The April 2026 statement takes a broader approach. Stevens referenced “chain migration” without confirming whether POLY remains the plan. He did not specify whether they will fork an existing chain or move to a different network entirely.
The Polymarket team has not officially named or shortlisted any specific chains. Despite this, speculation runs heavy across crypto communities.
Discussions on X and crypto forums center on Solana as a potential destination. Polymarket recently built a Rust-based perps backend, and Solana offers ultra-fast settlement with low fees. Because of this overlap, many view it as the frontrunner.
Some community members also noted a test “Polymarket” chain appearing on Avalanche. There is no confirmed link between that sighting and the official team. In the meantime, Polygon reportedly works with Polymarket on interim fixes.
No immediate action is required today. The Polymarket chain migration has not happened yet, and consequently no timeline exists.
When the migration eventually occurs, users will likely need to bridge funds to the new chain. This includes USDC, pUSD, or open positions. A short planned downtime window is also expected during the transition.
Polymarket has a track record of smooth user-facing transitions. For example, the current USDC.e to pUSD collateral shift in V2 requires minimal user friction. The team will almost certainly provide a guided migration experience.
The immediate priority for users is the CLOB V2 go-live on April 28. Bots and integrations must upgrade SDKs before then. Users should also close positions or migrate balances ahead of the one-hour downtime window.
Beyond V2, the Polymarket chain migration remains early-stage. The team confirmed it as a priority, but they have not announced a target chain or launch date. As the team evaluates options, the crypto community watches closely for further details.
This is not financial advice. Users should monitor official Polymarket channels for migration updates.
