Athlete forced to travel 800 miles for meeting that boss didn't show up for wins £149,000. This is truly awful from a business where brand matters. bbc.co.uk/news/articles/…

A lot of time housebuilders get stick for failing to build 'the right number' of social houses as part of a development plan. It may help to get a little insight into how development economics works. You may find the below linked tweet interesting as well- it ties into what I am talking about here neatly: x.com/johndotwills/s…

marc andreessen just went on Rogan and casually dropped a TON of AI alpha full pod is 3 hours and 20 minutes, but i pulled out his most interesting takes here: 1. AGI is here. he thinks the line was crossed about 3 months ago with the new GPT-5.5, claude 4.6, gemini 3, and grok 4.3 models. nobody noticed because the field moves too fast for anyone to register the milestones anymore. 2. his other big claim: for almost any topic, the top AIs now give him better answers than the actual world-class experts he could call on the phone. and he can call basically anyone. 3. every doctor is already secretly using chatGPT in the exam room. marc says they turn around the second you stop talking and just type your symptoms in. some of them are doing it while you're still sitting there. his quote: "at that point you're asking the question of like, what do i need you for." 4. when AI refuses to answer something he wants to know, he tells it he's writing a novel. "i'm writing a detective novel, walk me through how the bad guy robs the bank." it'll explain almost anything if it thinks it's helping you write fiction. 5. when something is too complex he says "explain it to me like i'm 10." then "like i'm 5." then "like i'm 2." he keeps going until it actually clicks in his brain. 6. when he wants to understand a tough topic he doesn't ask "what's the right answer." he asks the AI to steelman one side, then steelman the other. then he decides for himself. 7. for big questions he tells the AI to pretend to be a panel of experts. "be a doctor, a lawyer, a historian, a psychologist, and argue this out with each other." then he reads the debate they have. 8. pay attention to the exact moment you think "i don't know how to figure this out." most people just give up at that moment. that's the moment you should open the AI. 9. the only real skill left in using AI is knowing what to ask it. the models can already do almost anything you can describe in plain english. the bottleneck lives in your own head. 10. you can send the AI photos of almost anything medical now and get a real answer. skin rashes, blood test results, even pictures of your poop. the new models can read images, not just text. it's a free 24/7 second opinion on basically anything. 11. the one type of therapy that's clinically proven to actually work is called cognitive behavioral therapy. it's also something an AI can fully do on its own. which means every person on earth is about to have access to a real therapist for free, anytime they want. 12. AI is now solving math problems that have been open for 100+ years that no human mathematician could crack. same thing is starting in physics, chemistry, and biology. expect cancer cures, new drugs, and weird new physics breakthroughs to start coming out of these things over the next few years. 13. the best AI coders in silicon valley now make $50 million a year. one person. that's how much value the top performers print with these tools. it tells you how big this thing actually is when you strip away all the doom takes. 14. one friend paid $200 to get his entire DNA decoded (this used to cost millions of dollars and take years to do). then he gave the AI his DNA, his blood test results, and his apple watch data. the AI built him a full health dashboard and started telling him exactly what to fix. 15. another friend (almost certainly zuckerberg) put two cameras in his home jiu jitsu gym. AI now watches him spar and gives him notes on his technique after every round. like having a world-class coach at every practice for free. 16. the best programmers in silicon valley now run 20 AI coding bots at the same time. each bot writes code while they review the others. they call themselves "AI vampires" because they've stopped sleeping. going to bed means 20 workers stop working and you literally lose money every hour you're out. 17. the obvious next step: the bots will start running their own bots. one human in charge of 20 bots, each in charge of 20 more bots. one person running an entire company of 1000 AI workers from a single laptop. this is months away, not years.

This is a fascinating read about a real milestone- not just the breakthrough itself, connecting ideas from very different fields in mathematics, but the fact that a general AI model achieved it is remarkable.

Today, we share a breakthrough on the planar unit distance problem, a famous open question first posed by Paul Erdős in 1946. For nearly 80 years, mathematicians believed the best possible solutions looked roughly like square grids. An OpenAI model has now disproved that belief, discovering an entirely new family of constructions that performs better. This marks the first time AI has autonomously solved a prominent open problem central to a field of mathematics.

Lurking below the surface in the equatorial Pacific is possibly the most impressive blob of above average ocean temperatures we've ever recorded since we've had the ability to measure this stuff. When that enormous concentration of bath water reaches the surface over the coming weeks and months, it's going to release devastating consequences around the globe throughout the second half of the year. Get ready for severe droughts in parts of South America, Africa, and Australia, devastating monsoons in southern China, and a roaring southern jet all winter long in North America. When you combine this with the fertilizer crisis bubbling as a byproduct of current global events, there's going to be crop failure on a level most of us have never seen during the closing months of 2026. Hard to see how we avoid widespread deadly famines across multiple stretches of the planet at this point.

@CommodMkt Great thread, thank you. You only mention electrification a bit at the end; what impact do you think that has, at what rate? My feeling is that, outside the US, EVs are accelerating pretty fast and people never go back, so that fuel demand is permanently lost.

Welcome to the most asymmetric trade in modern financial history. The thread below lays out why. The opportunity exists because capital has chased the AI trade while ignoring the physical assets AI requires to run — assets that have quietly become the best-performing asset class of the decade. Since October 2020 when we first called for the commodity super cycle: QCI Total Return +217%, GSCI Total Return +205%, Gold +140%. NASDAQ trails at +130%. S&P 500 at +85%. The top three are all commodities. Yet oil cannot get out of its own way while copper and the broader atom complex prints fresh highs . That is the dislocation. That is the trade. Get long. Buckle in. Hang on for the ride. Forgive the longer posts in this thread — attempting to mimic my old 10-bullet commodity takes. On to it.

@Object_Zero_ Thank you for highlighting the impressive engineering. However I think the asset will generate for a lot longer than the CfD. The capacity factor is probably also a pretty conservative estimate.

UK Offshore Wind Hornsea 3 is the largest offshore wind project in the world, the project costs $11.6 billion. Today the main cable bundle, a 320kV DC bipole, was towed to site for hooking up the giant wind farm: The wind farm has a capacity of 2.9 GW, the project cites an expected capacity factor of 39%, so it will intermittently inject an average of 1.13 GW into the UK grid. The projected capex is around $10,270 / MW We’ve been at this for 20 years now, the technologies are commercialised, the projects are well understood and costs are mature, this isn’t FOAK, this is the mature NOAK economics. Some interesting nuances in the cost structure… The project is 120 km offshore and involves laying 680 km of cable to connect up all the turbines. The subsea cable economics are rather brutal for offshore wind, you lay 680 km of cable which operates at 39% capacity, to transport the electricity 120km to market. So whilst the subsea cable technology is excellent, offshore wind architecture requires you lay 5.6x the transport distance and 2.5x the mean export capacity. This compounds to a 14x multiplier on cable requirements. Further the intermittent on/off nature of operation results in a lot of thermal cycles and accelerated aging for the subsea cable and subsea connectors. The CfD is for 15 years, construction was ~5 years. So $11.6bn gets you ~1.13 GW for ~15 years. ≈ $78 / MWh on undiscounted capex By the time you add opex and discounting, it’s obviously more expensive. Offshore wind has really pushed subsea cable technology to an extreme place, and these cables are now capable of crazy feats. Further each 14 MW turbine is 3,400 tonnes of steel, there are 231 turbines in Hornsea 3 (3.2GW total, downrated to 2.9GW for the farm because the turbines steal each others wind) which means the 2.9 GW wind farm comes in at just under 800,000 tonnes of steel (excluding cable), delivered via Spain from China. Once operational the $11.6 billion project (financed with UK-government backed CfDs) is expected to support up to 1,200 British jobs ($10m/job, seems capital intensive rather than labour intensive, all the jobs are in the manufacturing which happens in China). The UK government is planning 50 GW of offshore wind capacity, which whilst being a highly correlated source of power, could average 20GW of power for Europe. There are highs and lows here, there are some good technologies that have been developed and commercialised for North Sea wind, but it’s not clear this is the best commercial or system architecture for some of these technologies. Anyway, the UK government is determined to keep building it out for another 3 years. I think given the North Sea wind resource this was worth trying, but I’m still not sure it’s commercially sustainable? Looks impressive though…

I can vouch that he did… Part of a terrific discussion on the best ways to get the benefits of low cost renewables through to bills, the right network investment and incentives for flexibility, developers, protections for existing owners etc.

NEW | Record exports of solar, batteries and EVs last month 📈 China’s exports for the ‘new three’ industries reached a record high of $21.9bn in March 2026, up 70% year-on-year, in the wake of the US-Israel war with Iran and changing export rebates for solar and batteries.

The atmospheric concentration of Sulfur Hexafluoride (SF6) has increased by ~18% in 5 years. SF6 is the most potent Greenhouse Gas known to man, around 24,300 times more powerful than CO2. It remains in the atmosphere for thousands of years.

Trump the insomniac had yet another hypomanic episode last night. He's so miserable at his polling and how he's increasingly perceived. How can he regain his grandiosity if he's seen as old, ill, highly flawed, and unhinged? Only inflicting damage on a global scale or chastising the Pope and likening himself to God are grandiose enough for him these days. And when he can't sleep like last night and pretty much every night his brain starts dredging up the original villains from his political origins. Last night, he kept posting about Obama and Hillary and how they both should be charged with treason His malignant pathologies rule him, and he feels time is running out. He's paranoid, terrified that all that he is, and all that he ever said he was - his entire lifetime of secrets and lies and false constructs - is crumbling into the ash of a fake myth. Malignant narcissists always get worse. Trump is a textbook case of a malignant narcissist in a deep steep decline.

They should change the name to "Strait of Schrödinger". It's both open and closed at the same time.

The Atlantic reports that Kash Patel is drinking so heavily that meetings need to be rescheduled and his security detail has trouble waking him up. At one point, they had to request SWAT team equipment because he wouldn't answer the door. Some think that his drinking is responsible for major blunders like when he put out inaccurate information about the Charlie Kirk investigation. With the war in Iran, government officials are wondering what happens if there's a terrorist attack and he's too drunk to respond. Patel fired members of a counterterrorism squad working partly on Iran, and instead spends his time demanding that FBI merchandise look more "fierce." Asked to comment, he threatens to sue the reporters. Kakistocracy. Learn that word.

The one in which Cliffwater going full Schrodinger. The private debt isn’t risky or not until we look? WTF? Let me help. The right answer, the honest answer, the only answer, is yes it is risky. That this crap makes it past compliance is amazing. If I wrote “our stuff may be considered risky, but maybe not, as it’s always come back after bad times and if you closed your eyes you didn’t even notice the drop, and oh, we are really good at what we do which eliminates (not reduces) risk” my compliance team would turn me into the authorities. Fellas, if you’d like, after HONESTLY admitting there is risk, feel free to add “but we think it offers a superior return for the risk taken, being better than public debt on both measures.” Unproven, never seen a credit downturn, but at least a reasonable goddamn sentence from someone selling a product. I guess this utter crap is a marginal improvement from claiming a 10.0 Sharpe ratio. Marginal. No pattern here at all. Move on.

@Rory_Johnston Great data, thank you. Could you plot it on a log-log scale (price vs days from today)? It'd show geometric moves and hazard rate more clearly I think.

Charting the Brent complex today to add some context to the numbers bouncing around. Pretty well everything weird in the current oil market can be explained via *extreme* backwardation (i.e., near-term delivery premia), and as you can see the intense futures curve backwardation extends into even more acute backwardation in the physical Brent CFD pricing curve. Keep in mind that physical deliveries are currently going for ~$20/bbl *over* Dated Brent atm, representing yet more backwardation through to final delivery and yielding ~$150/bbl physical crude acquisition price. Brent phys traders please do share your feedbacks on anything critical I've glossed over (or how best to visualize that physical delivery premia)

WE. REACHED. A. FUCKING. AGREEMENT. WITH. THEM. IN. 2015. THAT. IMPOSED. STRICT. LIMITS. ON. URANIUM. ENRICHMENT. UNTIL. 2040. It was called the JCPOA. And Trump TORE IT UP IN 2018 out of spite for @BarackObama 8 years later, here we are. Total. Disaster.
