A Columbia study found that up to 60% of Polymarket’s volume may stem from wash trading, raising new concerns about artificial activity in prediction markets. The rapid growth of the prediction market Polymarket may not be entirely organic but instead inflated by artificial trading activity, according to research published by Columbia University. In an 80-page paper titled “Network-Based Detection of Wash-Trading,” which has not yet undergone peer review, Columbia researchers identified extensive wash-trading activity on Polymarket beginning in July 2024. That month, they found that wash trades accounted for nearly 60% of the platform’s total trading volume. “This activity persisted through late April 2025 before subsiding substantially, and once again increased to about 20 percent of volume in early October 2025,” they wrote.

Bitcoin bulls have held the price above the critical $100,000 support level, but a shallow bounce increases the risk of a breakdown. Will altcoins gain ground while BTC searches for direction?

Is ETH’s deflationary edge fading? Could XRP’s speed, compliance and liquidity network make it the next global bridge in digital finance? Since Ethereum’s Merge update in 2022, the network’s transition to a deflationary model has steadily reduced the supply of Ether (ETH), increasing its scarcity and reinforcing long-term investor confidence. The reduced supply has elevated ETH beyond a simple utility token, positioning it as a potential store of value within the broader cryptocurrency ecosystem. In contrast, XRP (XRP) has carved out a distinct role as a bridge asset, facilitating instant cross-border liquidity for banks and global payment networks. Read more

Some Republicans’ initial plans to have crypto market structure out of committee by November have been sidetracked by the government shutdown. The shutdown of the US government entered its 38th day on Friday, with the Senate set to vote on a funding bill that could temporarily restore operations. According to the US Senate’s calendar of business on Friday, the chamber will consider a House of Representatives continuing resolution to fund the government. It’s unclear whether the bill will cross the 60-vote threshold needed to pass in the Senate after numerous failed attempts in the previous weeks. Amid the shutdown, Republican and Democratic lawmakers have reportedly continued discussions on the digital asset market structure bill. The legislation, passed as the CLARITY Act in the House in July and referred to as the Responsible Financial Innovation Act in the Senate, is expected to provide a comprehensive regulatory framework for cryptocurrencies in the US.
