Goldman Sachs: Retail investors account for roughly 30% of US stock market trading volume, with their trading turnover hitting a new record high in June.

Bank of America CEO Brian Moynihan has joined a host of Wall Street leaders in voicing serious concerns over AI models such as Mythos developed by Anthropic. “This marks a huge shift in workload, and also relates to how quickly these tools can impact system vulnerabilities, as well as how fast we need to respond,” Moynihan said. In recent months, the rapid evolution of AI models has prompted the financial industry and the U.S. government to begin assessing potential threats. Anthropic claims that Mythos, which launched earlier this year, excels at identifying system vulnerabilities. Bank of America is among the Wall Street institutions granted access to Mythos; the bank has used the model to test its own systems and share information with peers. The model is not yet open to the public. Earlier this week, JPMorgan Chase CEO Jamie Dimon warned that widespread public access to the system would be “as dangerous as handing a ballistic missile to an individual.” (Jinshi)

According to Fortune, Visa has launched a stablecoin platform that provides one-stop stablecoin services for banks and fintech companies, helping them integrate stablecoins into existing payment, settlement and fund flow systems. Visa aims to make it easier for its roughly 15,000 financial institutions and over 200 million merchants to use stablecoins through this platform. The firm processes around $15 trillion in annual payments and has already settled billions of dollars worth of stablecoin transactions to date. The platform will integrate Visa’s existing stablecoin services, reducing the complexity of blockchain technology for its clients, allowing them to focus on optimizing payment experiences. Merchants using stablecoins will benefit from instant settlements and lower transaction costs. The platform will strategically launch with OUSD, a stablecoin introduced by Open Standard two weeks ago, as its foundational infrastructure, while also adding support for USDC and USDG, which Visa already backs. Visa is a partner of Open Standard, and American Express and Mastercard are also involved in OUSD-related collaborations.

Sleepagotchi is rebuilding the Web3 health economy by building an AI-powered decentralized health application. The project started as a "sleep-to-earn" mobile mini-game, where users earned digital collectibles for maintaining consistent sleep habits. The team later expanded it into a full-fledged health app that analyzes data from phones and wearables via AI to generate personalized health insights. Sleepagotchi CEO Kenny Wood noted that the team has found sleep to be the root cause of nearly all health and emotional issues, with poor sleep negatively impacting mood and overall well-being. The project now aims to combine on-device AI and utility-focused crypto infrastructure to deliver personalized health recommendations without sending sensitive biometric data to corporate cloud servers or on-chain. The app uses a decentralized multi-agent system, where sleep coaches, health coaches, meal planning agents, and shopping agents handle various tasks locally on users’ phones, with status data transmitted in real time. On the crypto mechanism front, Sleepagotchi plans to use its native stakable token, SLEEP, to support its future marketplace and advanced health tracking features. Users can access basic health insights and automated guidance for free, but additional AI queries beyond the daily free tier require payment in SLEEP. The project also plans to monetize via advanced health tracking subscriptions, marketplace listing fees, partner staking deposits, and affiliate revenue from its shopping agents. Sleepagotchi has secured $6.5 million in funding, with investors including 6th Man Ventures, Collab+Currency, Sfermion, 1kx, Alliance, and GSR. Project documents show it has over 2 million users and generated more than $100,000 in revenue during its three-week test period.

Moonshot AI’s official website has updated its new KIMI K3 model; users can access two versions—K3·Max and K3 Cluster·Max—after logging in, with an official full announcement expected soon. Earlier, sources revealed the model has a parameter scale of 2 trillion to 3 trillion, making it the largest AI model developed in China to date, with capabilities approaching those of models from leading U.S. AI lab Anthropic. This development signals that the gap between China and the U.S. in cutting-edge AI is narrowing. As the benchmark counterpart, Anthropic has not yet officially disclosed the exact parameter scale of its models. However, industry insiders widely speculate its Opus 4.8 model has around 1.5 trillion to 2 trillion parameters.

Crypto journalist Eleanor Terrett reported that the U.S. Senate passed a resolution by unanimous consent yesterday, stating that FTX founder Sam Bankman-Fried (SBF) should not receive a presidential pardon. The resolution, introduced by Senators Ruben Gallego and Cynthia Lummis, is an official political statement from the Senate recording its opposition to pardoning SBF. However, the resolution is not legally binding, so it will not prevent the U.S. president from pardoning SBF in the future, nor will it have a direct impact on his current legal situation.
