#预测市场 Polymarket migrates from Polygon to a self-built L2, and this move is worth paying attention to. The Polygon outage on December 18 directly affected the platform's operations, and it now appears to be the trigger point.

Several signals worth tracking:

**On-chain fund transfer signals** — How tokens and liquidity move to the new L2 will leave obvious on-chain traces. Large cross-chain bridge transactions during migration can be tracked through these contract operations to gauge the scale of funds.

**The practical significance of infrastructure improvement** — Abandoning third-party providers (GoldSky, Alchemy) and launching its own L2 POLY indicates that Polymarket aims to establish an independent tech stack. This is not only for stability but more importantly to control data flow and user experience. Prediction markets demand high real-time performance and data accuracy, and building its own infrastructure can address this pain point.

**5-minute markets as a new trading vector** — Ultra-short cycle markets will attract high-frequency traders. Coupled with L2 scalability, this is a typical strategy to compete for liquidity and trading volume.

In the short term, there may be liquidity gaps during migration, but once completed, the trading efficiency and costs of prediction markets are expected to improve significantly, which is a substantial benefit for ecosystem expansion. It is worth paying attention to the fund inflow data after the new L2 goes live.
