According to a cnbeta report on market capitalization, domestic DRAM memory pioneer Changxin Technology has officially surpassed internet giant Tencent to become China’s most valuable listed company, reaching a market capitalization of 3.5 trillion RMB ($485B). This seismic realignment represents the crowning of China’s state-backed semiconductor self-reliance drive over traditional consumer internet platforms, reflecting national strategic priorities that are fundamentally reshaping the global technology supply chain.

Tech & AI

China’s generative AI landscape took a massive leap forward as Alibaba open-sourced its flagship Qwen3.8-Max model, a 2.4-trillion-parameter system whose weights are now public, matching global closed-source systems in long-term autonomy and agent capabilities. On the same night, DeepSeek launched the formal version of its V4 Pro model, scoring just 0.1 points behind Anthropic’s Fable 5 on the Terminal Bench agent evaluation, though the startup simultaneously announced a sharp 11x API price hike during peak hours to manage skyrocketing compute demands. These rapid open-weights advances contrast sharply with Google Gemini’s delayed release schedules, with sources attributing Gemini’s multi-month delays to severe chip shortages, internal divisions, and the high-profile exit of AI pioneers Jeff Dean and Oriol Vinyals to launch a rival startup. Meanwhile, Elon Musk is heavily turning to natural gas to power his massive xAI and SpaceX “Colossus” supercomputers in the US, utilizing off-grid generators to bypass years-long utility connection delays as AI electricity demands reach unprecedented heights. To bolster its voice assistant, Apple is offering a unique pay-per-use licensing model, discussing a multi-million dollar budget to pay publishers for real-time news in Siri AI.

Consumer & Devices

The explosive global demand for AI chips is squeezing consumer devices, as a report on the death of sub-$100 smartphones reveals a 64% drop in ultra-low-end US phone sales as RAM and NAND flash components now consume over 64% of their manufacturing costs. Legacy hardware is also buckling under heavy AI workloads; Tesla HW3 motherboards are overheating to 96°C and bricking after FSD OTA updates, a hardware crisis that highlights the protection offered by China’s strict “approve-before-push” regulatory policy that bans heavy updates on under-powered hardware. In contrast, premium niche features are thriving, as Sony’s Xperia 1 VIII reported strong sales due to its stubborn retention of the 3.5mm headphone jack and microSD slot, which premium users highly value. Meanwhile, folding screens continue to struggle with durability, with iFixit’s teardown of the Samsung Galaxy Z Fold8 showing severe hinge vulnerabilities to fine dust and awarding the device a dismal 4/10 repairability score.

Gaming

The Chinese gaming industry saw the dark resolution of its most notorious tragedy as legal details of the Yoozoo Games poisoning case were officially published, detailing how former executive Xu Yao meticulously manufactured multiple lethal toxins to poison founder Lin Qi over corporate disputes before being executed on May 21. In the corporate sphere, Netflix is scaling back its gaming ambitions by shutting down internal studios like Night School (creator of Oxenfree) to focus on lower-risk external IPs. On a more positive note, Warner Bros. officially confirmed Hogwarts Legacy 2, marking a heavy reinvestment in its billion-dollar franchise following the original’s record-shattering 40 million sales.

Science & Space

For future space exploration, China’s 2035 lunar base construction plans propose deploying quadruped robotic dogs to handle water-ice mining and habitat assembly, shielding human astronauts from extreme lunar hazards. In astrophysics, an international team studying a magnetar has captured the strongest evidence of vacuum birefringence, confirming Werner Heisenberg’s 1936 quantum prediction that “vacuum is not empty” by measuring highly polarized X-ray emissions through intense magnetic fields. Additionally, astronomers captured a supernova shock breakout of the Type Ic supernova SN 2026gzf, a rare event that reveals the violent, final-decade mass-loss histories of massive Wolf-Rayet stars.

封面故事

根据 CNBeta 关于市场估值的报道，国内 DRAM 存储龙头长鑫科技正式超越互联网巨头腾讯控股，成为中国市值最大的上市公司，收盘市值达到 3.5 万亿元人民币。这一历史性的市值重组，标志着中国以国家支持的半导体自主可控战略正式超越了传统的消费互联网平台，也反映出正在从根本上重塑全球科技供应链的国家战略优先级。

前沿科技与人工智能

中国生成式 AI 领域迎来重大突破：阿里开源其旗舰大模型 Qwen3.8-Max，这款 2.4 万亿参数的超大规模模型首次对外开放权重，在长期自主性和智能体能力上比肩全球顶级闭源系统。同夜，DeepSeek 正式上线 V4 Pro 商业版本，在 Terminal Bench 智能体评测中与 Anthropic 顶尖模型 Fable 5 的差距仅剩 0.1 分，但为应对极度紧缺的算力需求，API 价格在高峰时段大幅上调 11 倍并引入峰谷定价。与中国开源力量的突飞猛进形成鲜明对比的是，谷歌新一代 Gemini 模型发布再度延期，多方消息称其正深陷芯片短缺、内部资源内讧的泥潭，且 AI 元老 Jeff Dean 和 Oriol Vinyals 宣布离职携手创业。与此同时，马斯克大举转向天然气发电，计划依靠数十台燃气轮机为 xAI 和 SpaceX 的“Colossus”超级数据中心及 Texas 的太瓦级芯片厂自备供电，以绕过美国公共电网长达数年的并网延迟。在生态构建方面，苹果则正探讨数亿美元预算，拟采取浮动报酬机制，向新闻出版商付费以引入实时资讯到 AI 版 Siri。

消费电子与智能设备

全球 AI 算力热潮正严重挤压低端消费电子市场，一项 关于千元以下智能手机消亡的行业报告 显示，受存储芯片价格飙升影响，美国 100 美元以下手机销量暴跌 64%，内存和闪存占其零部件总成本比例已突破 64%。老旧智能设备在重载 AI 下也暴露出巨大缺陷：特斯拉 HW3 主板在更新 FSD 后过热至 96℃ 并频繁趴窝，这一危机凸显了中国“先审核、后推送”智能汽车监管政策的前瞻性，该政策明确禁止向算力不达标的老旧硬件推送重载算法。相比之下，高端细分市场则凭独特卖点突围：索尼 Xperia 1 VIII 销售表现极其强劲，因其固执地保留了微型 SD 卡插槽和 3.5 毫米耳机孔而获得极高用户评价。然而，折叠屏领域的铰链和防尘难题依然无解：iFixit 对三星 Galaxy Z Fold8 的拆解 显示其铰链在微小灰尘测试中会发出可怕的嘎吱研磨声并导致无法正常展开，最终仅给出 4/10 的极低可修复评分。
