Penguin Solutions (PENG) is down about 40% from the 52-week high its best quarter ever bought it, thanks to its own $750 million convertible notes deal. The stock fell again Monday even as chip stocks like Broadcom and Micron rebounded and the broader market closed roughly flat.
Microsoft (MSFT) is testing Moonshot's Kimi K3 for Copilot to cut its Azure AI bill by $600 million
Microsoft is testing Moonshot's Kimi K3 for Azure and Copilot, hoping to cut AI costs by $600 million, the same week the model's launch gave chip stocks a rough ride and its maker began prepping a $30 billion Hong Kong IPO.
Nvidia (NVDA) and Microsoft (MSFT) don't just sell OpenAI chips and cloud time. They also fund the bill.
Nvidia, Microsoft, Oracle, Broadcom, AMD, and CoreWeave have promised OpenAI close to a trillion dollars combined, and some of them are OpenAI's investors as well as its vendors. Here's how the money actually loops, and where it's already showing strain.
I gave five AIs a pretend $10,000 to pick 5 tech stocks. Four bought Nvidia (NVDA). Claude went rogue.
ChatGPT, Gemini, Grok, Meta AI and Claude each picked five tech stocks to hold for six months. Four bought Nvidia. Claude went the other way. Every pick is here and the scoreboard runs monthly.
Broadcom just picked its next supplier, and it is not Samsung Electronics or SK Hynix.
Samsung Electro-Mechanics and LG Innotek, not Samsung Electronics or SK Hynix, are racing to supply Broadcom with the substrates its AI chips sit on. One has already won Broadcom's business and is shipping glass substrate samples. The other is fielding trillion won investment offers to catch up.
China's Xi Jinping just launched a 29-nation AI bloc. That's bullish for US AI stocks (NVDA, PLTR)
Xi Jinping used the 2026 World AI Conference in Shanghai to launch a 29-nation World AI Cooperation Organization and take a shot at US chip export controls. History says Washington answers moves like this with money, and that is bullish for the US AI trade.
Chips got smoked today. Tomorrow's CPI report at 8:30am decides what happens next.
Arm, Coherent, Micron, AMD and Nvidia fell between 3.5% and 7.5% Monday while Microsoft, Apple and Amazon finished green. The selling stayed inside crowded AI infrastructure names. Tuesday's 8:30am CPI report could send the same stocks sharply either way, and the real risk isn't even in the data yet.
SK Hynix's $28 billion Nasdaq debut names Leopold Aschenbrenner's fund as a cornerstone investor
SK Hynix's record roughly $28 billion Nasdaq listing (SKHY) drew a cornerstone commitment from Leopold Aschenbrenner's Situational Awareness fund. The twist: the fund's single biggest disclosed position is a bet against the chip sector, which makes an anchor check into a memory chipmaker the story worth watching.
Samsung's record beat couldn't stop a memory stock selloff, and Micron (MU) is caught in it
Samsung posted a record 89.4 trillion won ($58.5 billion) Q2 operating profit, up 18-fold year over year, and the stock still opened lower. Memory names like Micron, SanDisk, and Western Digital are down sharply while the broader Nasdaq 100 barely moved. This is still developing after-hours and can change fast.
Broadcom (AVGO) and Apple (AAPL) extend their chip deal through 2031, and AI is part of it now
Broadcom filed two sentences with the SEC about extending its Apple chip deal to 2031. The 3.7% pop came from reporting about an unconfirmed AI chip, not from anything Broadcom actually said. Here's what's confirmed and what isn't.
SemiAnalysis says Nvidia's Kyber AI rack is delayed to 2028: what it means for NVDA, AMD, and the photonics trade
SemiAnalysis says Nvidia's Kyber NVL144 rack is delayed more than a year to 2028, its backup design was scrapped, and Rubin Ultra was quietly cut in half. NVDA barely moved and AMD jumped instead. Here's what it means for the wider photonics trade, from Coherent and Lumentum to POET Technologies.
Micron (MU), Nebius (NBIS) and chip stocks jump on Hyperliquid's weekend tape
Real markets are closed for July 4th, but tech and chip stocks are trading green right now on Hyperliquid's 24/7 stock perpetuals. Micron, Marvell and Nebius lead the bounce, and the S&P 500 and Nasdaq perpetuals are up too. Here is the full read, and why Monday could look nothing like this.
Do politicians actually beat the stock market? What the data says
Nancy Pelosi, David Rouzer, Ro Khanna and more: do members of Congress really beat the stock market? What the research and the yearly reports actually show, and whether copying their trades works.
Chips had their third worst day of 2026 and the S&P barely noticed (MU, INTC)
The S&P 500 closed within a whisker of flat on July 1 and the chip trade still had its third worst day of the year. Micron fell 10.5 percent, Intel lost 9 percent, and Meta gained almost 9 percent on the other side. Here is the damage report.
The AI stocks that led and lagged the first half of 2026
The first half of 2026 split the AI trade in two. Memory and chip-supply names like Micron (MU, +304%) and Intel (INTC, +278%) soared, while marquee names lagged and AI software fell, with Palantir (PLTR) down about 34%. Here is the full scoreboard and what it means.
Smart money is piling into AI neoclouds: Nebius NBIS, SharonAI SHAZ and Cerebras CBRS
Several top funds disclosed 5%+ stakes in AI compute names this spring: Leopold's Situational Awareness in Nebius (NBIS) and SharonAI (SHAZ), Tiger Global in Cerebras (CBRS), and Lone Pine in miners turned AI data centers TeraWulf (WULF) and Hut 8 (HUT).
The hidden chokepoints behind the AI chip boom
Everyone watches Nvidia and TSMC. But the AI chip boom rests on a few obscure materials, often from one company, country, or town: ABF substrate, photoresist, high-purity quartz, neon and gallium. Who controls them, and how big the risk really is.
It is not just the chips: optics, memory and the neo-clouds all sold off this morning
The whole AI build-out sold off Monday morning, not just semiconductors. Optical names like Coherent (COHR) led the drop, memory (MU) and the neo-clouds fell hard, and Nebius (NBIS) was the lone holdout. What is going on.
What is a chip foundry? Why almost every AI chip is made by one company, TSMC (TSM)
Nvidia, Apple and AMD design chips but do not make them. A plain-English guide to what a semiconductor foundry is, the fabless model, why TSMC (TSM) makes around 70 percent of the world's chips, and the packaging bottleneck holding back AI.
The AI shortage keeps moving: from GPUs to memory, and now to hard drives (STX, WDC)
The AI shortage keeps rotating down the supply chain: first GPUs, then compute and networking, now memory, and hard drives are the leg lighting up next. The pattern, the stock moves at each stage, and what could be next.
The AI stock map: every layer of the trade, from sand to software
A top-to-bottom deep dive on the AI supply chain, from the machines that make the chips down to the hyperscalers writing the checks, and how every layer pushes and pulls on the others.
