China's CXMT flips to $11.5B profit as memory prices ride the AI wave

Two stories that put the AI boom's hard infrastructure on the front page: a Chinese memory chipmaker just printed its first massive profit, and an AI-powered brand-protection tool has booted a popular open-source game off Google Play with a takedown that doesn't even name a single infringing asset.

CXMT, China's largest memory chipmaker, reported roughly $22.4 billion in H1 revenue and about $11.5 billion in profit — more than double its full-year 2025 sales and a sharp reversal from a year-ago loss. The numbers, reported by Bloomberg, confirm what memory buyers have been saying for months: AI-driven demand for HBM and high-density DRAM has finally turned China's domestic memory champion into a real cash machine. The story matters because CXMT is the only credible Chinese alternative to Samsung, SK Hynix, and Micron, and the HBM market is one of the tightest chokepoints in the entire AI build-out. A profitable CXMT means Beijing's chip self-sufficiency push just got its strongest commercial proof point — and a second source for the world's hottest memory category. The catch: U.S. export controls still keep the most advanced HBM out of CXMT's hands, so this profit is mostly standard DRAM and DDR5 riding a price upcycle, not a true HBM breakthrough.

Luanti, the open-source voxel game engine formerly known as Minetest, was pulled from Google Play after a DMCA takedown notice generated by Tracer.AI, an AI-driven brand-protection service used by Microsoft's Mojang. The notice claimed Luanti was shipping copyrighted Minecraft assets but did not name a single asset, file, or texture — Luanti ships with no games or assets at all, only an engine that loads community-uploaded content. This is the latest in a string of bogus AI-generated copyright claims that have hit open-source projects with no resources to fight back, and it shows a real-world failure mode of agentic enforcement: a model files a confident-looking legal notice, a platform complies automatically, and the burden falls on the victim to file a counter-notice and wait out a 46-day clock. The takeaway isn't that brand-protection AI is bad — it's that platforms still treat AI-generated notices as trustworthy by default, and open-source maintainers pay the price.

What to watch: whether Google's counter-notice process restores Luanti quickly, and whether Microsoft/Mojang or Tracer.AI acknowledge that an AI agent should not be filing legal notices without human verification.

If your open-source project can be taken down by an AI you don't employ, who is on the hook when the takedown is wrong?

Mistral unveils Le Chonk: a 1T-parameter open-weights model

The biggest open-weight release outside China lands in public preview today, and the country that spent the week promising its own frontier model just put a price on the ambition. Mistral has opened a public preview of Mistral Large 4 — codenamed "le Chonk" — a 1 trillion-parameter mixture-of-experts model with 49 billion active parameters, natively multimodal, which the company calls its largest and most capable model to date. The preview API is live today on Mistral Studio at $1.36 per milli

Google signs 3.6 GW power deal, a quarter of it new nuclear

Grid capacity, not chips, is becoming the binding constraint on the AI buildout — and on the same day, the labs told an Australian inquiry they can live with mandatory incident reporting. Google has contracted 3.6 GW of power from Constellation Energy across the PJM grid — the largest electricity deal in the region's history, and the biggest single power commitment any AI company has made. The agreement covers 3,590 megawatts over 13 states, with 890 megawatts of new nuclear capacity coming fr

Korea probes AI agents in bank hacks as president cites 'signs'

South Korea opened a formal investigation into whether AI agents drove a wave of bank breaches — and it isn't the only AI story moving money today. President Lee Jae Myung said "signs" point at AI models, and the probe is now at the highest level a national banking sector has seen. Speaking at a cabinet meeting, Lee said that "in some hacking incidents, signs have emerged of AI being used, causing considerable public concern and anxiety," and police have since opened a full-scale investigation

Open Source Radar — October 6: nothing leaves your machine

Today's trending board is all projects we ran earlier this week, so the fresh signal comes from the Product Hunt launch slate instead — three open-source tools that share one instinct: your phone, your pixels and your MCP traffic should stay on hardware you control. All three verified at the source. iphone-use (Rust, MIT, about 59 stars) is computer-use for a real iPhone: an agent reads the screen as text, taps, swipes and types over WebDriverAgent, and every action comes back with an honest v
