Investor Mark Cuban and "Big Short" Michael Burry recently issued warnings about the valuation risks of Nvidia (NVDA) and AI stocks. Cuban stated on the X platform that the current AI capital cycle bears similarities to the internet bubble of the 1990s, believing that Nvidia is playing the role of the IPO market back then, driving continuous capital inflow by supporting customers in purchasing AI chips.Burry, on the other hand, is concerned about the rising prices of Nvidia's credit default swaps (CDS) and claims that the scale of "circular financing" driven by Nvidia is expanding. He believes that some AI demand relies on financing support, and future revenues may be built on complex funding cycles. Previously, Nvidia's stock price fell about 5% in a single day, with a market value shrinkage of approximately $250 billion. The IMF and the Bank for International Settlements have also warned about the systemic risks that AI circular financing may bring. However, Nvidia CEO Jensen Huang responded that the related criticisms are "absurd."

Jiang Yi, Director of the Policy Research Office of the National Development and Reform Commission, stated at a press conference on July 31 that in the first half of the year, China's pace of independent innovation in artificial intelligence has accelerated. Domestic companies such as Deep Exploration and Dark Side of the Moon have successively released open-source large models with parameter scales reaching "trillion" levels, and the global download volume of domestic large models has surpassed 10 billion times. The next step will focus on strengthening research and development in cutting-edge areas such as the basic theory of large models, training and inference efficiency, multimodality, and intelligent agents, and accelerating the layout and construction of national artificial intelligence application pilot bases, while vigorously cultivating intelligent derivative enterprises.Jiang Yi pointed out that there will be a coordinated approach to high-quality development and high-level security, accelerating the legislative process of the "Artificial Intelligence Law", constructing a "development---regulation---security" closed-loop system, establishing and improving technical monitoring, risk warning, and emergency response mechanisms, and adhering to the development concept of "human-led, for human use, and benevolent to humanity," actively responding to the impact of artificial intelligence on economic operation and employment distribution.

A 24-year-old German genius faced a margin call after a 4x leveraged bet on AI was hunted by Wall Street, and after Citadel took over at a discount, the next day the stocks surged by 15%-29%.

Chief Economist of Bitfire Group, Fu Peng, stated that the AI industry is currently in a transitional period from the midstream to the downstream. The infrastructure layer, represented by Nvidia, has entered a mature stage, displaying characteristics of established stocks. However, the downstream application layer has yet to see a milestone breakthrough similar to ChatGPT. The next 10 to 18 months will be a transitional period for the industry cycle. He indicated that the competition in the second half of AI will no longer be about the story of repeatedly burning money to build infrastructure, but rather whether AI, as an efficiency tool, can generate stable payments, profits, and diffusion after entering real industries.He also mentioned that current market funds are following a logic of narrowing focus, prioritizing the elimination of speculative assets that are peripheral, highly elastic, and lack cash flow support, while continuously concentrating on the most core and highest certainty targets. Pure liquidity assets at the denominator end, such as Bitcoin, often digest valuation pressure before traditional stock markets.He further noted that DRAM and HBM storage are ultimately commodities, subject to the laws of commodity cycles. When the industry fundamentals are extremely certain and volatility drops to very low levels, the excessive accumulation of off-market financial leverage often becomes an invisible killer that triggers a sharp decline. Even when a company's fundamentals are sound, prices can fluctuate dramatically during deleveraging.

CryptoQuant analyst Darkfost stated that since December of last year, the supply of Bitcoin held for over one year has continued to increase, with the recent monthly average reaching +217,000 coins, indicating that many holders who bought at higher prices are still holding on.However, he pointed out that while this builds a solid foundation for the market, it also reflects the current weak demand—during the strong bullish rebound, the supply held for over one year has consistently been negative, as short-term holders rushed in during the bull market while long-term holders took profits. The analyst believes that Bitcoin is building the necessary foundation for a healthy bullish recovery, but this will take time, and rebuilding real demand is a long-term process. Patience is needed at present, but the overall trend is positive.

According to a report by the South China Morning Post citing informed sources, ByteDance's AI business has achieved an annual revenue of $4 billion, the highest known level in the domestic market, but still far behind leading AI companies in the United States. Previously, ByteDance announced through an internal email the integration of the Feishu and Doubao product teams and GTM system, with Doubao head Zhao Qi leading the product line and Volcano Engine head Tan Dai responsible for the new ToB GTM organization "Creativity Service Platform," aimed at building "stronger AI product competitiveness and customer service capabilities."This integration is the largest adjustment to the ToB business since ByteDance's business segmentation in 2021. The Doubao enterprise version, developed with the participation of the Feishu team, has already entered internal testing with some clients. The report pointed out that ByteDance's AI revenue mainly comes from enterprise API calls of the Doubao large model, AI cloud services, and enterprise-level AI solutions.

According to The Defiant, ENS Labs Chief Operating Officer Katherine Wu released an executable draft proposal for the establishment of the ENS Foundation on Thursday, abandoning the plan to transfer the DAO operational wallet to a new entity after weeks of opposition from representatives to previous versions.As disclosed, the draft will keep approximately 54.6 million ENS tokens and an operational wallet holding about 16 million dollars in ETH and stablecoins under the control of token holders. The only ENS token transaction in the proposal is a one-time transfer of 1 million tokens, solely for the compensation of foundation staff with a multi-year vesting period. The foundation's board will gain management rights over an approximately 65 million dollar donation fund treasury, but each transaction must go through a time lock, and the security committee has the right to cancel.ENS DAO officials summarized this revision as authorizing the foundation to manage the donation fund while token holders retain control over the protocol, the remaining ENS held by the DAO, the operational wallet, and the appointment and dismissal of foundation directors.
