The U.S. stock market's AI sector suffered a "Black Tuesday", with Micron and SanDisk plunging over 13%, and both the optical module and storage sectors were not spared.

X (formerly Twitter) has announced the launch of its "Original Content Reward Program", which aims to reward creators who provide original perspectives, professional analysis, news reporting, creative content, and comments. X stated that it will immediately stop accepting new applications for its Revenue Sharing Program. Existing Revenue Sharing users will continue to receive earnings until September 7, 2026, with their final three payments scheduled around August 14, August 28, and September 11. Starting from September 8, eligible existing creators can apply to join the new Original Content Reward Program. The new program distributes earnings based on "valid impressions" from original content—defined as views from X Premium users’ home feeds where posts are at least 50% visible. The first payment under the new program is expected to be issued on August 28. Eligibility requirements include: being at least 18 years old, having an account in good standing, subscribing to X Premium or Premium+, holding at least 500 verified followers, accumulating at least 500,000 impressions from verified users’ home feeds over the past 90 days, and consistently publishing original content. X emphasized that the new program prioritizes rewarding original writing, threads, reporting, analysis, videos, images, design works, and comments with unique value. Content such as simple reposts, scraped content from other platforms, secondary posts lacking substantial analysis, or content using automated tools to generate engagement will not qualify for rewards. X noted that it will focus future support on creators who bring unique perspectives, professional expertise, and creativity to the platform.

JPMorgan noted that despite the overall strong performance of the U.S. corporate earnings season, stock prices have responded relatively weakly to earnings beats, with even some tech companies seeing share declines after reporting strong financial results. The bank attributes this phenomenon to multiple factors, including the market having already priced in high expectations for corporate earnings, investors being overly concentrated in tech sector positions, and the market’s focus gradually shifting from short-term performance to companies’ future capital expenditure plans. Particularly in the tech sector, investors are reassessing whether companies’ large-scale investments in areas like AI infrastructure will deliver long-term returns, with earnings beats alone no longer sufficient to support further stock price gains.

The XRP Ledger (XRPL)’s latest software version 3.3.0 introduces multiple upgrade proposals, including the “Confidential Transfers” feature designed to deliver enhanced privacy protection for institutional users. The feature encrypts token balances and transfer amounts while retaining visibility into accounts and token types, and is primarily targeted at Multi-Purpose Tokens (MPT) on XRPL, with use cases covering tokenized financial assets such as funds and bonds. Using encryption technologies like zero-knowledge proofs, the network can verify transaction validity without disclosing specific amounts. Per CoinDesk, XRPL currently holds around $1.38 billion in on-chain real-world assets (RWA), including approximately $845.7 million in RLUSD. In addition to RLUSD, there are over $530 million in tokenized assets on XRPL, issued by entities including Ondo, VERT Capital, Archax, and Société Générale. Beyond Confidential Transfers, XRPL version 3.3.0 includes five other proposals: Batch, Sponsor, Permission Delegation, Dynamic MPT, etc., addressing institutional needs such as batch transactions, fee sponsorship, permission management, and dynamic adjustment of token attributes. However, these upgrades have not yet been officially launched; they require sustained support of over 80% from XRPL trusted validator nodes for two weeks before activation. The market is watching whether institutions like Aviva and Ondo, which have already issued assets on XRPL, will adopt this privacy feature.

According to monitoring by TradingBeats (formerly Hyperinsight), a crypto whale opened a 40x short position on 930 Bitcoin at an entry price of $64,213, and currently holds an unrealized loss of $710,900, with its latest liquidation price standing at $65,306.

Citrini analyst Jukan stated that South Korean PCB and packaging substrate manufacturers are expected to sustain their strong Q2 performance, with further improved profit expectations for Q3. Taking Daeduck Electronics as an example, the company’s Q2 revenue reached 401 billion won, up 63% year-over-year; operating profit hit 70.3 billion won, surging 3,599% YoY. Simmtech recorded revenue of 514.6 billion won in the same period, up 51% YoY, while its operating profit rose 1,035% YoY to 62.9 billion won. TLB posted revenue of 88.2 billion won, up 38% YoY, with operating profit growing 86% YoY to 12.8 billion won. Jukan pointed out that Daeduck Electronics’ core advantages lie in FC-BGA, FC-CSP semiconductor packaging substrates and multi-layer PCBs (MLBs) needed for AI data centers; Simmtech focuses on packaging substrates and storage module PCBs; TLB mainly supplies server DDR5 and enterprise SSD-related PCB products. He noted that as leading industry players such as Taiwan’s Unimicron prioritize allocating production capacity to high-value ABF substrates and reduce BT substrate capacity, some BT substrate orders may shift to South Korean manufacturers, bringing new growth opportunities for Daeduck Electronics and Simmtech. Additionally, Jukan emphasized that SOCAMM is emerging as a new growth variable. With NVIDIA’s next-generation AI platforms, Vera Rubin GPU and Vera CPU, set to enter the shipment phase, demand for SOCAMM PCBs is expected to heat up, benefiting related suppliers Simmtech and TLB and further driving growth in the AI infrastructure supply chain.

Serenity stated in a post that the White House has finally ramped up investment in critical minerals and materials, a "surprising" policy move that will help advance the construction of U.S. critical supply chains. Among publicly traded firms, FEAM secured $8 million in funding for boron material development, while HREE received $4.8 million earmarked for magnetic rare earth materials. Additionally, the U.S. government has allocated funding to private enterprises, including a $150 million investment in Niron Magnetics and $85 million in Standard Bauxite. Serenity noted that while these funding sums are just "pocket change" for the U.S. government, they can leverage extensive downstream industrial applications and play a key role in reducing critical material supply chain risks. However, he added that current investment levels remain insufficient to fully resolve supply chain issues, requiring more funding in the future to accelerate the implementation of critical mineral projects and mitigate industrial chain development risks. Serenity emphasized that he does not hold stocks in any of the aforementioned companies and only endorses the policy direction.
