SemiAnalysis: Kimi K3 significantly reduces KV (Key-Value) transmission bandwidth, but AI network demand will not shrink as a result.

According to South Korea’s Maeil Business Newspaper, SK Group Chairman and Korea Chamber of Commerce and Industry Chairman Choi Tae-won stated that driven by the expansion of artificial intelligence (AI), demand for AI semiconductors is projected to rise by at least 60% to 100% next year compared to this year, while overall memory chip demand will also grow by at least 50% to 60%. Choi noted that the additional supply each company can increase next year is very limited, so the supply-demand gap may widen further, with global firms currently scrambling for memory chip supplies. He added that existing expansion plans are still insufficient to meet the rapidly growing demand; SK’s current strategy is “build wherever possible”, but equipment, personnel and construction timelines continue to restrict capacity release. Choi also pointed out that current memory chip prices have deviated from normal ranges, and PC and smartphone manufacturers cannot keep passing cost increases to consumers. Semiconductor enterprises should not limit supply to maintain high prices; even if their profit margins decline, they should expand output and grow the market. Otherwise, excessive prices may attract new competitors and trigger government interventions. He further stated that the AI industry is facing shortages of infrastructure such as GPUs, storage and power, and new bottlenecks may emerge in the future. Regarding the possibility of a stock split for SK Hynix, Choi said the plan has not been fully studied, and adjustments for Korean domestic stocks and American depositary receipts (ADRs) need to be evaluated together.

The Kobeissi Letter stated in a post that the three-week volatility of U.S. momentum stocks relative to the S&P 500 index has surged to four times, hitting an all-time high. This ratio has more than quadrupled over the past several weeks. The momentum stock group includes high-growth tech stocks at the center of the AI boom, such as NVIDIA, AMD, Palantir, D-Wave Quantum, and CoreWeave. By comparison, the ratio peaked at around 2 times during the 2020 COVID-19 market crash and roughly 1.8 times during the dot-com bubble burst. The current level is significantly higher than those periods. Meanwhile, the U.S. momentum stock index has dropped 24% since July, marking its largest monthly decline since the 2008 financial crisis. The stocks that previously performed the strongest are quickly losing market favor.

Renowned crypto trader Doctor Profit announced in a post that he has closed all his cryptocurrency short positions, including Bitcoin shorts established in the $115,000–$125,000 range, another Bitcoin short in the $79,000–$82,000 range, and over 100 altcoin shorts opened in recent months, noting that all these positions have generated significant profits. He also said he has repurchased Bitcoin spot at $64,000, marking his first long-term allocation since September 2025. His plan is to invest 5% of his planned capital daily in spot Bitcoin purchases when the price is in the $54,000–$64,000 range, for up to 20 days total; if the price approaches $54,000, he will increase his buying activity. Doctor Profit pointed out that the current market is showing clear "herd behavior": investors who were previously bullish on Bitcoin up to $150,000 at high levels are now widely waiting for the cryptocurrency to drop to $40,000–$50,000, and are targeting September or October as the bottom of the four-year cycle. When a large number of investors are waiting for the same price level and time point, the market may not move as expected, so he chose to build positions in advance and judges that this cycle’s bottom may arrive earlier than the market’s general expectation. He also cited regulatory clarity, asset tokenization infrastructure, and progress in institutional adoption as the structural reasons for his shift to buying, and retracted his previous prediction that Bitcoin would fall to $40,000–$50,000. However, he still holds all his S&P 500 short positions, arguing that the crypto market has completed a large repricing, while U.S. stock valuations remain elevated.

Zcash has launched its new full-node client Zakura 1.0.0, the first implementation component aimed at scaling its private transaction throughput from the current ~1 transaction per second (TPS) to payment-network-level capacity. Maintained by Sean Bowe, an early Zcash zero-knowledge cryptography contributor, and Dev Ojha, head of Valar Group, the client operates independently of the Zcash Foundation and is funded via private ZEC donations. Built on the Zcash Foundation’s Zebra client, the team provides an ~11GB blockchain snapshot, allowing new nodes to sync up in two minutes—an approximately 680x speed improvement. Its compatibility mode also replicates the legacy zcashd interface, enabling wallets and exchanges to continue operating after the original client’s maintenance ends on July 18. The team notes that Visa and Mastercard process over 50,000 transactions per second, a benchmark it has set as its minimum target. To reduce the verification burden of large-scale private transactions, Bowe’s Tachyon project is developing recursive proofs, which let nodes validate thousands of proofs with a single proof. Valar Group is building private information retrieval (PIR) technology, allowing wallets to access relevant transaction data without exposing their query content. Zakura is also testing a fast block propagation system that delivers new blocks to all nodes in half a second. Its upcoming testnet is the Ironwood upgrade, set to activate on the mainnet on July 28. Ironwood will use a "rotating door" mechanism to restrict inflows and outflows of the Orchard privacy pool, mitigating risks of fake ZEC entering circulation due to prior zero-knowledge proof vulnerabilities.
