On 9 December 2025, the UK Financial Conduct Authority opened a consultation inviting crypto companies to comment on plans to overhaul how investment products and client categories are regulated.

Industry participants have until February and March to respond, as the UK increasingly weaves digital assets into its broader financial and legal framework.

Research released on December 8, 2025, identified a data aggregation error that causes most third-party dashboards to double-count Polymarket trades and overstate reported volume by about 100%, according to Paradigm. Adjusted calculations place October and November 2024 volumes at roughly $1.25 billion each, while major data providers move to update their metrics.

In November 2025, the U.S. Securities and Exchange Commission (SEC) ended a two-year investigation into Ondo Finance without recommending enforcement action.

On December 9, 2025, Storm Slivkoff, a research partner at Paradigm, said Polymarket’s trading volumes are effectively counted twice on most analytics dashboards due to redundant on-chain events. Summing the platform’s OrderFilled events records both maker and taker legs, making a $4.13 YES/NO trade show as $8.26 in reported volume. Paradigm built a simulator to show how different metrics behave across at least eight Polymarket trade types and to help analysts correct volume calculations.

On 9 December 2025, researchers released a snapshot that ranks blockchain networks by the number of unique wallet addresses rather than price or trading volume. The data shows Ethereum with just over 273 million addresses and BNB Chain with roughly 272 million, far ahead of Tron, Solana, TON and smaller chains like Polygon, NEAR and Bitcoin. The figures point to strong network effects at the top while mid- and lower-tier ecosystems steadily expand their communities.
