NOAA’s Climate Prediction Center moved from El Niño Watch to El Niño Advisory on 11 June. The distinction is not cosmetic. A watch says an event is likely to form; an advisory says it has arrived. The June discussion put a 63% probability on a very strong event during November through January, which would put it among the largest in the record back to 1950, and a 97% chance conditions persist into early spring 2027.

Sandisk closed Wednesday at $1,350.50, down 5.4% on the session, then traded down toward $1,257 after the fiscal fourth quarter release. The stock is up roughly 490% year to date and has been the best performer in the S&P 500 in 2026. Its fifty-two week range runs from $40.53 to $2,354.39, the high set on June 22. Market capitalization sits near $200 billion on 148.1 million shares outstanding, with a beta of 4.

Beijing moved on four fronts on Wednesday and only one of them made the headlines. Exports of drones, their key components and related technologies now face case-by-case scrutiny when the destination is the United States, effective immediately, with no access to the licence facilitation measures that normally speed shipments through. Six American entities went onto the countermeasures list. A seventh was added under a separate justification. An investigation opened into imported office equipment running foreign system software.

Tempus AI reported GAAP net income of $5.6 million for the quarter ended June 30, the first positive bottom line in its public history, and the number is almost entirely an accounting event. Loss from operations widened to $75.9 million from $61.8 million a year earlier. The line that closed the gap was $97.4 million of fair value changes on marketable equity securities, non-cash and non-recurring by construction. Strip it out and Q2 was a larger operating loss on slower growth.

New survey data puts support for in-class cellphone bans for middle and high school students at 77% of US adults, up from 74% last year and 68% in 2024. Opposition sits at 18%. Nine points in two years is a fast move for a public opinion question, and the direction is what makes it interesting. Most policy questions with this profile — restricting something a majority of households own and use constantly — tend to soften as people work out how the restriction would affect them personally.

A wave of funding just landed on agent supervision, and the practical question for anyone running infrastructure is what the tooling does that existing monitoring and access control do not. Three capabilities are genuinely new. The rest is repositioning. Action chain tracing Traditional application monitoring records requests, latencies, errors, and traces across services. An agent produces a different shape of telemetry: a sequence of tool calls, each individually valid, chosen at runtime by a model whose reasoning is not in the log.

London-based Agon has emerged from stealth with a $7 million pre-seed and a $23 million seed round, developing sovereign AI training infrastructure aimed at European defense customers. The company is being funded against a gap that European defense ministries have been describing publicly for two years. Applying machine learning to intelligence, surveillance, targeting, and electronic warfare requires training runs on classified data, and training runs require compute at a scale that no European defense ministry owns internally.

I’ve spent two years arguing that AI detection tools are close to worthless. I still think the studies showing they flag non-native English speakers at higher rates are damning, and I still think any university disciplining a student on the strength of a probability score is committing an injustice it will eventually have to apologize for. None of that has changed. But there’s a category of case where the objection collapses, and we just watched a clean example of it.

Published cryptanalysis results on HAWK and AES show that AI systems can now absorb existing cryptanalytic work, convert it into new attacks, and extend those attacks beyond what the original research achieved. No cipher was broken. The capability being demonstrated is the automation of the research process that produces breaks, which is a different and more consequential claim. For anyone running a cryptographic migration programme, the significance is about scheduling rather than about any single result.

Arm reported first-quarter revenue of $1.29 billion, up 22% year over year against a $1.26 billion consensus, with royalty revenue up 22% to $715 million and a second-quarter profit forecast above estimates. Qualcomm reported third-quarter revenue of $9.95 billion, down 4%, guided fourth-quarter profit below estimates, and told the market that revenue from Apple will fall faster than previously expected. The stock dropped more than 7% after hours. Those two prints describe the same handset market from opposite ends of the value chain, and only one of them is shrinking.
