OpenAI is facing new legal challenges related to the mass shooting in Tumbler Ridge, British Columbia. Bloomberg posted on X that the lawsuits claim the AI company could have prevented the suspected shooter from accessing its widely-used chatbot, ChatGPT, prior to the incident. The legal actions argue that OpenAI's technology played a role in the events leading up to the attack, raising questions about the responsibilities of AI companies in monitoring and controlling the use of their products. The lawsuits highlight ongoing concerns about the potential misuse of AI technologies and the ethical obligations of developers in preventing harm.

Andre Cronje has expressed concerns that most decentralized finance (DeFi) protocols no longer adhere to the strict definition of DeFi, resembling more closely team-operated commercial systems. According to Odaily, this has sparked industry debate over whether 'circuit breakers' should be introduced to mitigate attack risks. In an interview, Cronje highlighted that early DeFi focused on immutable smart contracts, but many current protocols rely on upgradable contracts, multi-signature permissions, off-chain infrastructure, and manual processes. This shift has transformed them from 'immutable public goods' to 'operable profit-driven businesses.' He noted that recent security incidents, including attacks involving approximately $280 million and $293 million, have expanded industry risks from smart contract vulnerabilities to infrastructure, permission control, and social engineering attacks, akin to 'Web2-style risks.' To manage these risks, Cronje's Flying Tulip has recently implemented a circuit breaker mechanism, delaying or queuing withdrawals during abnormal fund outflows to provide a six-hour emergency response window, aiming to prevent systemic runs and further losses. However, this mechanism has sparked controversy. Michael Egorov argues that circuit breakers could introduce new centralized attack vectors if controlled by signatories or administrators, potentially becoming new security vulnerabilities or sources of freeze risks. He emphasized that DeFi design should minimize human intervention rather than increase manual control nodes. Industry analysis suggests this debate reflects DeFi's shift from the ideal model of 'code as law' to a practical framework of 'hybrid governance and operational control,' with security boundaries being redefined.

Silver prices have fallen to $72 per ounce, marking the lowest level since April 7, according to Odaily. This represents a daily decline of 1.53%. Meanwhile, the U.S. Dollar Index (DXY) has climbed to an intraday high of 98.77. In the oil market, both West Texas Intermediate (WTI) and Brent crude oil prices have seen short-term increases, with the latest reports showing prices at $105.75 and $107.79 per barrel, respectively.

In March 2026, prediction markets saw a total transaction volume of $25.7 billion, marking a 10.6% increase from the previous period. According to Odaily, the trading activity was predominantly concentrated among small retail users. Of the 1.29 million wallets tracked in the first quarter, 82.3% of users engaged in transactions below $10,000. The growth was mainly driven by micro, light, and moderately active user groups, reflecting a market structure characterized by high-frequency participation with low transaction sizes. Cryptocurrency assets served as the primary entry point for prediction markets, accounting for 39.6% of micro-user activity. Bitcoin-related event contracts attracted approximately 593,000 users in the first quarter, with a transaction volume of $5.42 billion, making it the most engaged crypto prediction market. Ethereum and Solana recorded transaction volumes of $1.19 billion and $420 million, respectively. In terms of category structure, sports markets led with a transaction volume of $10.1 billion, followed by political markets at $5 billion, with geopolitical-related transactions accounting for $2.41 billion. Overall, crypto-related markets reached a total transaction volume of $7.3 billion. Analysts suggest that the growth in prediction markets is primarily driven by 'category expansion' rather than an increase in single transaction sizes. Micro users were active for an average of 2.5 days, participating in 1.45 categories, while medium users increased their activity to 9.9 days, engaging in 2.34 categories, indicating a shift from single speculative activities to sustained participation across multiple markets.

数据显示，2026 年 3 月预测市场总交易量达到 257 亿美元，环比增长 10.6%，其中交易行为高度集中于小额散户用户。在第一季度追踪的 129 万个钱包中，82.3%的用户交易规模低于 1 万美元，增长主要来自微型、轻度及中等活跃度用户群体，市场整体呈现“高频参与、低单笔规模”的结构特征。加密资产是预测市场的主要入口，占微型用户活动的 39.6%。其中比特币相关事件合约在一季度吸引约 59.3 万用户，交易量达 54.2 亿美元，成为参与度最高的加密预测市场；以太坊与 Solana 分别录得 11.9 亿美元与 4.2 亿美元交易量。从品类结构看，体育类市场以 101 亿美元交易量位居第一，其次是政治类市场（50 亿美元），其中地缘政治相关占 24.1 亿美元，加密相关市场整体交易量达 73 亿美元。分析认为，预测市场增长主要依赖“类别扩展”而非单笔交易规模扩大。微型用户平均活跃 2.5 天、参与 1.45 个类别，而中等用户活跃度提升至 9.9 天、参与 2.34 个类别，显示用户正在从单一投机转向多市场持续参与结构。（The Block）

Standard Chartered has expressed confidence in the resilience of decentralized finance (DeFi) despite recent setbacks. According to NS3.AI, the bank described DeFi as "bent, not broken" following the KelpDAO exploit on April 18, which resulted in $292 million in losses and affected the AAVE platform. The incident led to a 38% decline in AAVE deposits and a 31% drop in active loans, as stolen tokens were used as collateral for borrowing other assets. Geoff Kendrick from Standard Chartered remains optimistic, projecting that tokenized real-world assets will achieve a market capitalization of $2 trillion by the end of 2028, a significant increase from $35 billion in October 2025.
