A severe selloff cascaded across global markets as investors grew increasingly jittery over high-flying technology stocks and frothy artificial intelligence valuations. South Korea’s Kospi Index plunged 10% from a record high as traders dumped chip heavyweights, fueling a broader retreat in US equity futures and emerging market gauges. The rout marks a critical test for the AI-driven rally, with megacap tech names sustaining heavy losses while market watchers look to upcoming corporate earnings to potentially rescue the sector.

A vicious global tech sell-off sent shockwaves through international markets, underscored by a massive 10% collapse in South Korea’s Kospi as investors aggressively dumped semiconductor and artificial intelligence darlings.

Markets & Economics#

International markets took a severe hit as the rotation out of the “Magnificent Seven” bled into global equities, headlined by historic drops in memory chip giants SK Hynix and Samsung that triggered a 10% plunge in South Korea’s Kospi. Concurrently, the U.S. Treasury issued a 60-day sanctions waiver allowing Iranian oil sales, easing energy supply concerns and unlocking billions in revenue for Tehran as peace talks progress. Domestically, the S&P manufacturing PMI printed better than expected at 55.7, but underlying data revealed factory job cuts running at their highest levels since 2009 amid escalating costs. Adding to the geopolitical momentum, the U.S. Senate advanced an Iran war powers resolution to end hostilities, though Republican leaders are demanding a formal vote on any final deal to review potential sanctions relief.

According to a cnbeta report, China’s entirely domestically built “LingSheng” supercomputer has reclaimed the global #1 spot on the Top500 list with a sustained performance of 2.19 EFlops. The system introduces an “Online Acceleration” CPU architecture that integrates AI matrix acceleration units, marking a significant milestone in Sino-US supercomputing competition and enabling massive AI-driven scientific research without relying on traditional heterogenous GPU architectures.

Google’s stock suffered a massive drop after two key AI figures—AlphaFold co-creator John Jumper and Transformer co-author Noam Shazeer—left for Anthropic and OpenAI respectively, as reported in this cnbeta coverage. Expanding its own AI footprint, Qualcomm is in advanced talks to acquire AI chip startup Modular for approximately $4 billion to challenge Nvidia’s infrastructure dominance.

Fable 5 wrote a Windows kernel in 38 minutes Anthropic’s restricted cybersecurity model, Fable 5 (a limited version of Mythos), successfully wrote a bootable, NT-compatible Windows kernel in Rust from a blank directory in just 38 minutes. The model correctly implemented the scheduler, memory manager, and trap machinery, while autonomously debugging its own hardware emulation issues. It’s a staggering demonstration of frontier capability that shifts the security conversation from whether an AI can write a Trusted Computing Base (TCB) to the urgent bottleneck of how humans can formally verify code produced at this speed.

Closer to the Material, Ryo Lu | Compile 26 from Cursor is a highly recommended watch that rejects the “black box” slot-machine model of AI dev tools in favor of a transparent “Glass” UI paradigm. It offers a sharp, philosophical architecture discussion on why exposing an agent’s planning, state, and tool execution is necessary to preserve engineering judgment and taste as software generation costs approach zero.

Meta’s redesign of battery internal architecture—abandoning standard wound “jelly rolls” for die-cut stacked layers—demonstrates that when software efficiency reaches its limits, scaling edge compute requires fundamentally re-engineering physical hardware components to reduce impedance and prevent system brownouts.

Dutch lithography giant ASML has begun shipping its monumental $400 million High-NA EUV machines to Intel, a massive 150-ton bet designed to push the physical limits of chipmaking,. By enabling the production of transistor features as tiny as eight nanometers, this behemoth of a machine is the undisputed linchpin of the global semiconductor supply chain and will dictate the pace of AI hardware scaling for the next decade,.

Tencent has quietly rolled out its first native AI assistant, “Xiaowei” (小微), placing a highly visible green-eyed AI entry point directly on the WeChat homepage. This is arguably WeChat’s most significant update in years, as Xiaowei is deeply integrated into the app’s ecosystem, allowing users to execute tasks like searching their Moments timelines, summarizing chat histories, and directly calling mini-programs. By utilizing a user’s private social graph and chat memories as a unique context window, WeChat is leveraging its proprietary WeLM model to create a deeply personalized AI that general-purpose third-party chatbots simply cannot replicate.

Why I Love My Bad Days | Alexi Pappas | TED. Olympian Alexi Pappas shares her coach’s brilliant “rule of thirds”: when chasing a dream, you should feel good a third of the time, okay a third of the time, and completely terrible a third of the time. It is a remarkably practical psychological framework that recontextualizes your worst days as proof that you are pushing the boundaries of your potential, rather than failing.
