Deep Dive — OpenAI pulled its models out of Cursor. The fine print is the story.

On August 28, 2026, OpenAI notified SpaceX that it is exercising a contractual right it kept in its pocket for exactly this moment: the wind-down of its agreement to provide OpenAI models to Cursor, with a proposed shutoff date of November 12, 2026. The cutoff is not the news. The cutoff is the procedural part. The news is that OpenAI chose to make this public, name names, cite specific past contract violations as its reason, and explicitly carve out its next frontier model — Astra — from anythi

Deep Dive — Zhipu and MiniMax just broke the "sell the unlock" rule in Hong Kong

For eight months, the story of China's two publicly listed large-language-model companies was a story about gravity. Zhipu and MiniMax went public in Hong Kong in January, tripled and quadrupled, then spent the summer giving it back — Zhipu's stock halving from its peak, MiniMax losing nearly half its value in a single session when its own shares unlocked in July. On Monday, gravity broke. Zhipu hit its first post-IPO lockup expiry — the moment when early investors are finally free to sell — an

Big Tech's $160B paper-profit illusion hinges on Anthropic and OpenAI IPOs

The Q2 earnings beat looked enormous. Alphabet's net income tripled. Amazon's nearly did. New reporting from the Financial Times says more than $160 billion of those profits came from "other income" — mark-ups on the cloud giants' own stakes in AI labs, not from new ads, new shoppers or new AWS customers. The number is real under accounting rules and almost entirely unreal in cash. Whether it stays on the books depends on the next two IPOs. The mechanics are simple and circular. Alphabet booked

SoftBank hands OpenAI $5.5B in warrants to lock in Stargate

Two stories this hour on how the AI build-out is actually being paid for — and what happens to the open web once the scrapers show up. SoftBank's energy arm handed OpenAI roughly $5.5 billion in stock warrants, and the paperwork surfaced because SB Energy is about to go public. SB Energy, the SoftBank subsidiary building out the data center campuses behind Stargate, is preparing to file for a US IPO as soon as this week, targeting between $5 billion and $7 billion in proceeds. Buried in those I

Owner.com lands $240M Goldman Sachs round for its AI-native restaurant OS

A restaurant-management platform is the latest unlikely beneficiary of the AI capital flood, and the size of the round shows just how much the category has matured in twelve months. Owner.com raised $240 million in a round led by Goldman Sachs Alternatives, with the company positioning the capital as fuel for what it calls an "AI-native" platform built specifically for independent restaurants, not a bolt-on chatbot stapled to legacy point-of-sale software. The round, announced this week, marks

a16z's $1.1B Machine Age fund, Meta's India VP heads to OpenAI

Capital is finally catching up to the bottleneck. Andreessen Horowitz said Thursday it is standing up a $1.1 billion "Machine Age" fund dedicated to the physical layer of AI — chips, memory, interconnects, data centers, robots, and the cooling, electrical, and real-estate buildout they all need. The pitch is unusually blunt for a16z: the firm calls AI's advance a "social and national imperative," and says the next decade of returns will belong to whoever can ship faster, cheaper, and more power-

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

South Korea picks SK Telecom, KT, and Kakao to run AI-for-All

South Korea has picked SK Telecom, KT, and Kakao to run "AI for All," a public-utility program that will give every Korean citizen free, unlimited access to frontier AI chatbots and agents by the end of 2026 — and the government is putting real money behind it. South Korea just made AI a public utility. The Ministry of Science and ICT on Friday selected three operator consortiums — led by SK Telecom, KT, and Kakao — out of six applicants to run "AI for All," a program that will hand every Korea

Micron: HBM uses 3x the wafer of DDR5, and the gap keeps growing

AI's appetite for memory is colliding with a hard physical limit, and the chipmakers are running out of room to hide it. Two stories from the last 24 hours — one from a conference stage, one from a balance sheet — show the same problem from different sides. Micron used its Hot Chips 2026 presentation to make the case that the silicon cost of HBM, the stacked memory every AI accelerator relies on, has quietly tripled against ordinary DDR5, and the gap is widening with every generation. A single

Unisound's agent business clears 5B yuan in H1, token revenue jumps 500%

Two Chinese AI stories landed today that point in opposite directions on what "working" looks like at scale: a Hong Kong-listed industry-agent company posted real growth on a Palantir-style model, and one of the country's largest healthcare AI products inked a deal to plug authoritative Western medical journals into its doctor-facing app. Hong Kong's "AGI first stock" delivered a clean H1: revenue of 5.62 billion yuan, up 38.7% year over year, with the agent business alone accounting for roughl

OpenAI's Codex ships a 'Persistent' mode that runs until you stop it

The always-on agent race got a real code drop today. OpenAI is wiring a new "Persistent" setting into Codex's reasoning-effort menu — the closest a frontier lab has come to shipping a product around the idea of an agent that doesn't politely end its turn after a few minutes. Codex in Persistent mode is told to "continue working until put to sleep," according to a file in the Codex core that WIRED spotted in a recent pull request. That phrasing is doing the real work: today's reasoning modes sto

Nvidia pauses revenue-sharing deals with AI cloud firms

Nvidia's plan to become more than the chip supplier to the AI boom — to finance the data centers themselves and share in their revenue — just hit a speed bump. Nvidia has paused the revenue-sharing and credit-support deals it struck with AI cloud companies, people familiar with the matter told The Wall Street Journal, with Reuters confirming the move. The program, first announced in July, was Nvidia's bid to co-build "AI factories" with cloud providers — supplying Blackwell GPUs while taking a
