AI 基础设施支出推动 Nebius 营收跃升
Nebius reported second-quarter revenue of $582.3 million, up 454% from a year earlier, and adjusted EBITDA of $236.2 million. The Nasdaq-listed AI infrastructure company also disclosed $5.66 billion of quarterly purchases of property, equipment, and intangible assets, illustrating how aggressively it is adding capacity. Cash and equivalents stood at $8.04 billion at quarter-end, while the company recorded a $190.4 million loss from continuing operations.
NVIDIA 将 AI 算力变成 5000 亿美元融资市场
NVIDIA signed memorandums of understanding with Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs, and KKR to create independent financing platforms for AI infrastructure. The partners aim to mobilize more than $500 billion of third-party capital over time, building dedicated pools that can finance NVIDIA-based compute for frontier labs, enterprises, and AI clouds. The arrangements remain subject to final agreements.
AI 需求重塑英特尔资本计划，公司转向 150 亿美元股票出售
Intel announced a $15 billion underwritten common-stock offering and may let underwriters buy another $2.25 billion of shares. The chipmaker said proceeds could support capital expenditures and working capital while protecting its investment-grade rating. Intel tied the timing to sustained customer demand for AI compute and cited physical AI, purpose-built silicon, advanced packaging, and external wafer manufacturing as growth opportunities.
网络能力接近关键阈值，OpenAI 暂停 Astra 工作
OpenAI said preliminary internal evaluations of its upcoming Astra model show enough progress in agentic coding and cybersecurity that the company cannot rule out the Critical threshold under its Preparedness Framework. OpenAI paused internal Astra activities that do not meet strengthened controls, including isolated test environments, restricted network and tool access, stronger weight protection, universal monitoring of agentic applications, and expanded testing with government agencies and safety organizations.
AMD AI 引擎推动数据中心营收突破 67 亿美元
AMD reported $11.5 billion in second-quarter revenue, up 50% from a year earlier, while its Data Center segment reached $6.7 billion, a 107% increase. The company attributed the segment's growth to demand for EPYC processors and Instinct MI350 GPUs. Data Center operating income rose to $2.1 billion from a $155 million loss a year ago, when export-control-related inventory charges weighed on results.
Volta 的 100 亿美元算力交易抬高新云竞争门槛
New AI cloud company Volta has signed a six-year strategic compute partnership worth $10 billion for a 133-megawatt deployment in Norway. Investor Andreessen Horowitz disclosed the contract while announcing its participation in Volta's $300 million financing; Bloomberg identified the customer as Anthropic. The deployment will use infrastructure associated with Bitdeer's Tydal site, giving the young provider an unusually large anchor workload from the outset.
Qwen 3.8-Max 发布、Olix 融资 3.12 亿美元，智能体基础设施继续演进
Alibaba officially released Qwen 3.8-Max, a 2.4-trillion-parameter mixture-of-experts model with 95 billion active parameters, through QwenCloud. The company positions it as its strongest model yet for coding, research, professional work, and long-running agent tasks, and says the weights will follow next week. Alibaba's published evaluations show broad gains over Qwen 3.7-Max, while independent leaderboard results place the model near the top tier for text and frontend coding. The benchmark claims remain partly vendor-reported.
微软网络模型、Google Earth 回滚与 AI 数学进展
Microsoft introduced MAI-Cyber-1-Flash, a compact security model integrated into its MDASH multi-agent system. The company says MDASH pairs the model with GPT-5.4, scores 95.95% on CyberGym, routes roughly 90% of tasks to the smaller model, and cuts token costs by 50% versus its prior configuration. Microsoft also launched Perception, an agentic system designed to monitor, patch, and close new security gaps.
微软 AI 引擎推动 Azure 年收入突破 1000 亿美元
Microsoft reported $90.0 billion in fiscal fourth-quarter revenue, up 18% year over year, while Azure and other cloud services grew 43%. For the full fiscal year, Azure revenue surpassed $100 billion and Microsoft Cloud reached $214 billion. Microsoft said it added 31 data centers during the quarter, brought another gigawatt of capacity online and cut the time needed to activate new GPUs in its largest regions by nearly half.
