Hiro emphasizes that with the adoption and increasing transaction volume of sBTC, reliable tools like Chainhooks are crucial for the development of the ecosystem.

The decentralized prediction platform OracleX will officially launch its global public beta on December 1.The platform adopts a community-driven inclusive prediction mechanism, where the core mechanism Proof-of-Contribution (POC) views users' prediction behaviors as contributions (based on prediction frequency, accuracy, and scale weighting), and automatically distributes OEX rewards daily, allowing users to transition from participants to co-builders.In terms of the token model, OracleX employs a dual-token structure of OEX (governance) + USDX (stable), and introduces a dynamic ratio mechanism of 10%--50% along with a value stabilization system to reduce the potential risks of traditional algorithmic stablecoins.The team points out that in the increasingly crowded prediction space, "behavioral contribution proof" may become an overlooked important source of value, achieving a positive cycle where everyone can participate and contributions yield benefits. Meanwhile, Polymarket is valued at $12 billion, creating 35,000 markets monthly, but its long-tail market trades infrequently; OracleX aims to address this issue. OracleX positions itself as an inclusive prediction ecosystem and has planned a development path of cold start → multi-category expansion → building decision-making infrastructure.

According to Bloomberg, the decentralized prediction market platform Polymarket has quietly relaunched in the U.S. in Beta mode. Founder Shayne Coplan reportedly stated at Cantor Fitzgerald's cryptocurrency conference that the U.S. platform is "live and running," allowing selected users to bet on real contracts.The platform is said to be in the final stages before officially opening in the U.S. This soft relaunch marks a milestone for Polymarket after resolving a 2022 enforcement case with the Commodity Futures Trading Commission (CFTC), which forced the company to move overseas and resulted in a $1.4 million fine. In July 2025, Polymarket acquired the licensed derivatives exchange and clearinghouse QCX, laying the regulatory groundwork for its return to the U.S.After moving overseas, Polymarket experienced significant growth, especially during last year's U.S. presidential election. Last month, the platform set records with monthly trading volume, active traders, and the number of newly listed markets all reaching historic highs. However, its licensed competitor in the U.S., Kalshi, surpassed it in trading volume in October.Following its full relaunch in the U.S., the platform is expected to introduce its native cryptocurrency POLY, a fact confirmed by Polymarket's Chief Marketing Officer Matthew Modabber. This news has attracted more traders to participate in its prediction markets, as they seek to meet undisclosed short investment qualification requirements. As the prediction market space matures, becoming a legitimate fusion of information and finance, Polymarket has significantly expanded its influence by adding major partners.
