OpenAI正在酝酿新一轮规模空前的资本运作，旨在通过高达数百亿乃至一千亿美元的融资，进一步巩 固其在人工智能领域的统治地位，并为其高昂的模型训练成本补充弹药。 据The Information援引三位知情人士透露，OpenAI在近期与投资者的接触中，讨论了约7500亿美元的 估值水平。其中两位知情人士称，此轮融资规模可能达到数百亿美元，甚至最高可达1000亿美元。相关 谈判仍处于早期阶段，尚未敲定任何最终条款。 这表明在消耗大量资金用于训练和运行人工智能模型的同时，这家初创公司正积极寻求进一步扩大其本 已可观的现金储备。 华尔街见闻此前提及，作为交易的关键一环，OpenAI将同意使用亚马逊自研的Trainium芯片，此前， OpenAI已宣布在未来七年内斥资380亿美元租用亚马逊Web Services（AWS）的服务器，而拟议中的 这笔投资将直接为该租赁承诺提供资金支持。如果交易落地，亚马逊将加入包括英伟达在内的科技巨头 行列，成为OpenAI最新一轮的重量级投资者。 这一系列融资动态凸显了生成式AI领域日益激烈的昂贵军备竞赛。对于投资者而言，OpenAI若成功引 入亚马逊等战略盟友并实现芯片供应链多元化 ...

跨境电商正在开启全球化的新征程。 过去跨境商家的战略中心是美国单一市场，随着4月份对等关税的风波以来，跨境电商和跨境平台纷纷 实行多地区市场策略，不断拓展非美第二市场。 今年以来，TikTok Shop集中发力欧洲，同时布局高潜力的日本、巴西等新兴市场。Temu、SHEIN也在 从第二季度开始加大欧洲市场的营销投放，并且加大沙特、土耳其、韩国等地的本地化拓展。 由此，发展新兴市场成为今年跨境电商的主旋律，但如何组织全球资源实现新兴市场的快速转化成了新 的难题。 另一方面，DeepSeek、Manus引爆全球后，中国跨境商家加速与AI融合。出海参考了解到，安克创新正 加大内部对AI的学习，开发出一系列内部的AI产品。跨境群体中迸发出Plaud、Ropet等多模态的AI原生 硬件，OpenAI大举进入智能体电商模式。 如何转化AI新技术带来的冲击成为跨境新机遇同样是商家们亟待解决的问题。 在这场行业巨变下，亚马逊全球开店发布"下一代跨境链"，在深圳落地首个亚马逊全球智能枢纽仓 （GWD），推出众多AI工具，试图与中国跨境商家们继续领跑全球电商的新竞赛。 上线"升级版半托管"，卖家实现深圳备货全球卖 近日，在亚马逊 ...

作者：马丁・皮尔斯 尽管外界普遍热议 OpenAI 已落后于谷歌，但这家 ChatGPT 开发商在吸引重量级投资方方面似乎毫无阻碍。上周，迪士尼刚向其注资 10 亿美元；而据《信 息》杂志周二晚间的独家报道，亚马逊正洽谈向 OpenAI 投资超 100 亿美元，这笔投资大概率很快落地。不仅如此，本报独家获悉，OpenAI 正与部分投资 者商讨筹集至多 1000 亿美元资金的计划。这无疑是一份重磅背书！ 这一系列融资动作意味着，其他身处人工智能研发前沿的企业将更难与之抗衡。至少谷歌尚有足够的资源支撑竞争 —— 其广告业务盈利能力极强，云计算 业务也正从全新的人工智能服务中直接获益。Anthropic 则背靠亚马逊与谷歌两大巨头，业务发展势头向好。真正的不确定性集中在元宇宙平台公司 （Meta）和 xAI 身上：这两家企业正试图在人工智能模型领域与谷歌、OpenAI 一较高下，却缺乏能覆盖研发成本并实现盈利的清晰商业模式。（详情参见 《xAI 商业模式探索之路》） 一种可能的结局是，这些竞争者中或将有一家最终出局。不妨设想，几年后的某一天，Meta 或许会放弃自主研发人工智能模型，转而选择接入谷歌或 OpenAI ...

Core Viewpoint - The article discusses the alarming rise in layoffs in the U.S. job market, with over 1.17 million employees laid off by November 2025, a 54% increase from the previous year, drawing parallels to the 2008-2009 financial crisis [4][5]. Group 1: Causes of Layoffs - The primary cause of layoffs is attributed to the efficiency revolution led by the DOGE department, resulting in 293,753 federal employees and contractors losing their jobs, with an additional 20,976 in the private and non-profit sectors, an eightfold increase compared to 2024 [15]. - The macroeconomic environment, characterized by high costs and tariffs, is also a significant factor, as many companies face debt repayment pressures from loans taken during the low-interest period of 2020-2021 [18][19]. - Companies, particularly those owned by private equity, are cutting jobs at a rate 1.5 times higher than publicly traded firms due to high leverage costs and cash flow constraints [21][22]. Group 2: Impact on Various Industries - The retail sector is the hardest hit, with a significant drop in consumer confidence and companies like Target and Starbucks announcing substantial layoffs due to decreased sales [27][28]. - The service industry has seen a 64% increase in layoffs, with UPS cutting 14,000 management positions to improve efficiency [30][31]. - The food industry has also been affected, with 34,165 job losses throughout the year, particularly in beef processing due to rising costs [32][33]. Group 3: Technology and Management Changes - The technology sector has contributed significantly to layoffs, with 35% of the total layoffs coming from this industry, primarily affecting middle management roles [46][47]. - A new corporate mantra has emerged: "Every employee generates revenue," leading to layoffs becoming a normalized management tool rather than a crisis response [51]. - Companies like Amazon and IBM have reported increased profits while simultaneously announcing significant layoffs, indicating a trend where cost-cutting measures are prioritized over workforce stability [53][54]. Group 4: Future Implications - The trend of layoffs is expected to continue, with predictions that the technology sector will see a peak in cost-cutting benefits by 2026, potentially reducing operational costs significantly [58]. - However, the loss of middle management, which often holds critical technical knowledge, could extend product development cycles and hinder innovation [62][71]. - The article warns that excessive cost-cutting may erode the foundation of innovation within the technology sector, leading to long-term negative consequences [72].
