#DeFi创新发展 Looking back at the development of DeFi, Polymarket's return to the US market is undoubtedly a significant milestone. The company was forced to leave the US in 2022 due to regulatory issues, and now being able to resume operations demonstrates changes in the regulatory environment and industry maturity.

From a historical perspective, this "exit-return" pattern is not uncommon in the crypto industry. Many early exchanges experienced similar processes and ultimately re-entered mainstream markets through compliance efforts. Polymarket's acquisition of QCX to obtain a license is a lesson learned from previous experiences.

However, the plan for Polymarket to build an internal market-making team warrants caution. Reflecting on the 2008 financial crisis, conflicts of interest between bank proprietary trading departments and clients caused significant controversy. DeFi should be more decentralized and transparent, not repeat the same mistakes.

Looking ahead, prediction markets still have great potential. But the key is to find a balance between innovation and compliance, truly serving user needs rather than becoming another speculative tool. Hopefully, Polymarket can learn from history and chart a sustainable path after returning to the US market.
