This one was a heavy news week, the kind where you sit down to write your ten things and realize half the country was watching the same handful of them. A government stepping into the AI business. The biggest stock debut in history. Inflation back above four percent. The World Cup on our own soil. Some weeks the world hands you the list. How do you write about a week like that without just reciting it back?
Same deal as always. I go through what actually happened across the stuff I follow, and I write it down plain, the numbers and the names first, then a little of what I make of it. This is my hour to slow down and pay attention. Ten things, one sitting. Let's go.
AI, and the Money Behind It
1. The government drew a line by nationality, and Anthropic couldn't draw it, so it shut the models off for everyone
On June 12 the Commerce Department directed Anthropic, under export-control rules, to suspend access to two of its models, Claude Fable 5 and Claude Mythos 5, for foreign nationals. Not for everyone. For foreign nationals, whether they were inside the United States or outside it, and including Anthropic's own foreign-national employees.
Anthropic disabled both models for every customer instead. Segmenting a live product by the nationality of the person typing into it was not something it could practically do, so it turned them off across the board. Claude Opus 4.8 and the rest of the lineup stayed up.
The trigger, as officials described it to the company, was a technique for getting around Fable 5's safeguards on cybersecurity work, the kind that involves finding software vulnerabilities. Nobody has said publicly who found the technique. Anthropic pushed back hard and said it had not been given detailed written support for the government's position. It argued that a narrow potential jailbreak was a thin reason to recall a model deployed to hundreds of millions of people, and that applying that standard across the industry would "essentially halt all new model deployments for all frontier model providers."
I use these tools every day to run my business, so this one landed in my actual workflow and not just my news feed. But the part I keep turning over isn't the shutdown. It's that the order was written in terms of who you are rather than what the software does, and that turned out to be a line a modern software company can't draw. A model doesn't know your passport. So a rule aimed at some users became a switch thrown on all of them, including Anthropic's own staff.
One update, since this is going out after the fact: the administration lifted the restriction on June 30 and both models went back up worldwide. Eighteen days, start to finish. That doesn't change what the episode showed, though. It might make it worse, because the whole thing got walked back almost as fast as it was imposed.
That's going to keep happening. We're regulating something delivered instantly to everyone on earth using categories built for physical goods crossing a border, and when the categories don't fit, the fallback is the blunt instrument. Was the government wrong to worry? I don't think so. But the shape of the tool it reached for guaranteed the collateral damage, and that part was foreseeable.
2. SpaceX went public in the biggest IPO in history, and an analyst put fair value at less than half of it
On June 12, SpaceX listed on the Nasdaq as SPCX at $135 a share. It raised about $86 billion once the greenshoe was exercised, against a $75 billion target, which makes it the largest initial public offering ever run. The stock opened at $150, closed its first day at $161, up 19 percent, and finished the day worth roughly $2.1 trillion. The order book ran more than twice oversubscribed, somewhere around $150 billion chasing the raise, with about 30 percent of the offering set aside for retail buyers. Only about 5 percent of the company actually floated.
Here are the two numbers to hold against that. In 2025 SpaceX booked $18.7 billion in revenue and lost $4.94 billion. And Morningstar, looking at the same company on the same day, called it significantly overvalued and put fair value at $780 billion, against the $1.77 trillion the IPO implied.
I just wrote a whole piece on Musk, so I've been thinking about him a lot lately, and this is the part that gets me. Ordinary people can now own a slice of the rocket company, and they clearly want to. But a professional analyst looking at the same filings landed at under half the price. You don't get a gap that size out of rounding. Those are two completely different stories about what the company is.
You're not buying this year's books. You're buying a bet on what it becomes, and only five percent of it is even trading, which is part of why the price does what it does. That's the whole game with Musk, and I find him genuinely fascinating. I'd also read the fine print twice before putting my own money behind the story.
3. ChatGPT became the fastest app ever to reach a billion users
Around mid-June, estimates from app trackers had ChatGPT crossing one billion monthly users worldwide, making it the fastest app in history to get there, roughly three years after launch. For comparison, Google Maps, Chrome, YouTube, and TikTok each took somewhere between five and eight years. Google's Gemini app, meanwhile, was reported at more than 900 million monthly users, up from around 400 million a year earlier.
Whatever you think of these tools, the speed of adoption is the story. No consumer technology has ever scaled this fast, not the smartphone, not social media, nothing. And I say this as someone who was slow to it myself, and then didn't look back. A billion people didn't decide to use this because a billion people are experts. They used it because it turned out to be genuinely useful for very ordinary things. That's usually the sign a technology has stopped being a novelty and started being infrastructure.
The Economy Tightens Its Jaw
4. Inflation jumped to 4.2 percent, a three-year high
On June 10, the government reported consumer prices rose 4.2 percent over the year in May, the first reading above four percent in three years, up from 3.8 percent. Almost all of it was energy. Gas prices were up 40 percent over the year, driven by the oil disruption from the war in the Middle East. Here's the nuance that matters, though: strip out food and energy, and core inflation was actually tame, up just 2.9 percent. So the pain was concentrated at the pump, not spread across everything.
That distinction is the whole ballgame, and it's exactly what a scary headline flattens. So which one is this? A four-handle is genuinely alarming if it means broad prices have gotten loose again, if the thing is running through rent and groceries and the insurance renewal the way it did three years ago, because that kind takes years and a lot of pain to put back in the bottle. It's a different and far more survivable thing if what you're really looking at is a war and a pipeline, the kind that eases when the oil moves again. My read is mostly the second one. But mostly isn't entirely, and a long enough energy spike has a way of leaking into everything else, so this is one to keep an eye on rather than wave off.
5. The Fed held rates, and the new chair declined to say where they go next
On June 17, at Kevin Warsh's first meeting as chair, the Federal Reserve voted unanimously to hold its benchmark rate at 3.50 to 3.75 percent. Warsh was sworn in on May 22, so this was his opening statement to the markets, and what he mostly said was less.
The statement was cut sharply shorter and stripped of the easing-leaning forward guidance the Fed had been issuing under Powell. What replaced it was a flat promise: the committee will deliver price stability. The projections did the rest of the talking. All but one participating policymaker now expects rates to stay where they are or go up by the end of the year, with the median landing at 3.80 percent for 2026, and the officials tied the inflation pressure to the war with Iran. The missing dot was Warsh's own. He declined to submit a rate projection at all.
For a couple of years the entire conversation was about when the Fed would start cutting and make money cheaper again. This is the week that conversation flipped. If you run anything that depends on borrowing, and most businesses do, your base case quietly changed.
The detail I keep chewing on is the chair withholding his own dot. You can read that as humility, a man refusing to pretend he knows where rates are in eighteen months. You can also read it as a chair who doesn't want to be held to a number. Probably both. Either way it's a deliberate reduction in what the Fed tells you in advance, and anyone planning around cheap money later this year is now planning on less information than they had in May.
Medicine and the Body
6. A big study found younger generations are aging faster on the inside, and tied it to cancer showing up young
On June 22, WashU Medicine researchers published a study in Nature Medicine covering 154,169 young adults from the UK Biobank and 10,262 from the US All of Us program. They measured biological age against actual age, and found that every standard deviation the body ran ahead of the birthday came with about an 8 percent higher risk of an early-onset solid cancer. People in more recent birth cohorts carried bigger gaps than people born earlier, and by a lot: the group born between 1965 and 1974 came in 23 percent higher than the one born between 1950 and 1954.
The detail that makes it more than a headline is that the aging is organ-specific, and so is the cancer. An immune system that looked older than its owner was associated with early-onset lung cancer. Fat tissue that looked older than its owner was associated with early-onset colorectal cancer. Different systems running ahead, different diseases arriving early.
This is the kind of study that stops me cold, because it points at something a lot of us have felt and couldn't name. It isn't saying your birthday and your body are the same thing, which anyone who works around aging already knows. It's saying the gap between the two may be widening for younger people, and that the gap has consequences.
The honest caveat is that this is an association, not proof, and nobody has established what is driving it. But if it holds up, the payoff is a blood test that tells you how fast you're actually aging, organ by organ. In my line of work I watch the consequences of that gap every day, decades after the point where anyone could have done anything about it. A number you could see at thirty, while the arithmetic still runs in your favor, is the sort of thing I'd want to know. Wouldn't you?
7. The FDA approved the first antibiotic pill from a family that until now only came through an IV
On June 17 the FDA approved Utebzi, generic name tebipenem pivoxil, for complicated urinary tract infections including kidney infections. It is the first oral carbapenem ever approved. Carbapenems are the heavy artillery of antibiotics, and until now you got them through a line in your arm.
Two qualifiers the headlines mostly skipped. It is approved for adults who have limited or no alternative oral treatment options, so it is not a first-line pill. And GSK and Spero, who developed it together, expect it to actually reach US patients by the end of 2026, so it was an approval, not an arrival. The PIVOT-PO trial had it performing no worse than the IV standard, with diarrhoea and headache as the common side effects, all mild or moderate.
This is a small story that's bigger than it sounds. A pill that does the work of an IV can be the difference between going home and staying in a hospital bed for a few days. Anyone who has watched an older relative get admitted purely so somebody can run antibiotics through a line, and then watched the week go with it, the bad sleep and the worse food and the particular indignity of a gown that ties at the back, knows precisely what that costs, in money and in plain misery. I've sat in those rooms. Nobody gets better faster for being there.
No flashy breakthrough here. It's the quiet, practical kind that improves ordinary weeks for ordinary people, and I've come to appreciate that more than the flashy kind.
Wonder, Power, and Play
8. A Chinese company unveiled a grid battery made from salt instead of lithium
On June 22, the battery giant CATL introduced what it's calling the first field-validated sodium-ion battery for grid storage. The claimed specs are serious: units of more than 30 megawatt-hours, a 15,000-cycle life that works out to 25 or 30 years, and strong performance in deep cold, holding most of its capacity at 20 below. First deliveries are set for this fall.
The reason this matters is chemistry class simple. Lithium is scarce, contested, and expensive to dig up. Sodium is basically salt, which is everywhere and cheap. If you can build grid batteries out of salt, you loosen one of the tightest knots in the whole clean-energy story, the fight over a handful of minerals. These are company-claimed numbers on grid hardware, not something in your car yet, so I'm holding it loosely. But the direction, cheaper storage from abundant materials, is the thing that quietly decides whether the energy transition is affordable or not.
9. The Webb telescope read the weather on a planet 900 light-years away
Around June 10, a team led out of the Max Planck Institute used the James Webb Space Telescope to study an ultra-hot gas giant called WASP-121b, and found its dawn and dusk are wildly different worlds. The dayside runs around 2,770 Kelvin, hot enough to tear water molecules apart. The nightside is roughly 1,000. Fierce winds pile heat onto the evening side, so morning and evening on this planet have measurably different chemistry. It's the clearest proof yet that we can map conditions on a planet this far away.
There's no use for this, and that's exactly why I like it. A puffed-up, roasting gas giant 900 light-years off is nothing like Earth and will never matter to my Tuesday. But that we have built instruments which can sit here, on this one small planet, and read the difference between the morning side and the evening side of a world nine hundred light-years off, close enough to say the mornings are hazier than the evenings, is the part that gets me and I don't think it should stop getting me. The same toolkit, pointed at gentler planets someday, is how we'll eventually go looking for another Earth. We're building the eyes now, on the easy targets.
10. The World Cup kicked off in our own backyard, and a marquee drought ended in basketball
On June 11, the World Cup opened in North America, hosted for the first time by three countries at once, the US, Canada, and Mexico, with an expanded 48-team field and 104 matches. It began at the Estadio Azteca, where Mexico beat South Africa 2 to 0 in front of more than 80,000 people. Two nights later, in a different sport, the New York Knicks won their first NBA championship in 53 years, closing out the Finals behind a 45-point clincher from Jalen Brunson, capping a Finals that included the largest comeback in the event's history.
I'm putting these together because they're the same kind of story, the one where something a whole city or a whole country has been waiting on for years finally arrives. Fifty-three years is longer than I've been alive, and Knicks fans who were kids the last time are grandparents now. And a World Cup on American soil, the first in 32 years, turns a summer into an event you share with strangers. I don't follow either one that closely, honestly. But I never get tired of watching a long wait finally end. There's a lesson in it that has nothing to do with sports.
A Note to Myself
That's the week. Ten things, one heavy sitting.
The thread this time is power, I think. Who has it, who's reaching for it. A government reaching into a tech company. A trillion dollars of it changing hands in a single stock debut. A central bank deciding how expensive your money's going to be. And then, right alongside all that, a telescope reading the weather on a distant planet and a city crying over a basketball game. Both things are the world. It's good to hold them in the same hour.
Mostly for me, like always. But if you read this far, thank you. See you next week.
