SpaceX Blocked A U.S. And NATO Satellite to Assist a Russian Intercept After Crippling Ukraine's Air Defenses The Math Proves the Reality that Musk doesn't want you to see. On Oct 13-14, SpaceX restricted Starshield/Starlink during a 39-missile Russian attack, cutting Ukrainian drone intercepts by 23% and stranding U.S. personnel in Kyiv. Forty-eight hours later (Oct 15), SpaceX blocked U.S.-licensed NRO, Space Force, and NATO radar satellite ICEYE-X36 in orbit so Russia's COSMOS 2612 weapon could intercept it (99.89%-99.98% posterior) Our Model Demonstrates that the Russian intercept of the US/NATO ICEYE X-36 satellite (contemporaneous with the throttling of Starlink) would not have been possible, and almost certainly not been attempted, without SpaceX resources. At a material opportunity cost, Russia sprinted its COSMOS satellite to intercept ICEYE X36. Based on a previous attempt in June during which X36 maneuvered to evade COSMOS, Russia knew that this would be successful only if X36 could not maneuver. On October 15, SpaceX fixed X36 in place by issuing a collision alert for a sub-kilometer approach with its Starlink 35856 when SpaceX's own data shows that the actual distance was 4.8-5.0x as great. SpaceX issued no warning to COSMOS despite the fact that its sprint was far more threatening than the stable X36 orbit. SpaceX did not maneuver its Starlink 35856 satellite to clear the supposed collision risk. How, absent coordination with SpaceX, could Russia have known that SpaceX would take actions that (a) misrepresented the danger posed by X36, and (b) resulted in the fixing of X36 thereby enabling COSMOS's successful intercept? Thus, SpaceX was directly involved in simultaneously compromising Ukraine’s defensive and offensive capabilities. The conjunction of these two events makes innocent explanations untenable. The Pentagon Capture & Iran Round Two Trap: Pentagon CTO Emil Michael who cashed out $7M–$35M from Musk’s inner-circle SpaceX vehicles (M8/Gigafund 0.1 and M6/Valor M33 II) and KQ Partners / xAI (selling xAIfor $5M–$25M three days before taking over CDAO/OSCand 21 days before SpaceX bought xAI, while keeping M8, M6, M9, M10 & Nomadic open) and Pete Hegseth purged rival Anthropic in two hours, surrendered combat command over US drones used to attack Iran to Starlink’s "Terms of Service," and on October 2 named Musk Co-Director of Project Meridian to design the Pentagon's "Future of Warfighting" just as America enters Iran Round Twowith depleted Patriot/THAAD magazines and Russia feeding U.S. warship/aircraft locations to Tehran. SpaceX’s actions in Ukraine raise serious questions about its alignment with US security interests and its reliability as a cornerstone of US defense. These questions are particularly troubling given the effectively irreplaceable position SpaceX has been granted by the Hegseth/Emil Michael Pentagon. $SPCX $TSLA Our full quantitative analysis below w/ @streetwiseprof

funny how the # of customers hitting us up for neocloud capacity (even at large volume) is at an all-time high while neocloud stocks are at rock bottom wild divergence between fin bros and tech bros one side is pretty wrong. time will tell which :)

must feel good to be an Anthropic co-founder > help build chatgpt at OAI by training on world's collective knowledge > keep model weights closed to extract max profit from every token you sell > leave and launch a direct competitor > spend years and millions lobbying washington on how dangerous your own models are > get designated a supply chain risk by the pentagon and fail to ban OSS anyway > pay $1.5bn to settle over 500k pirated books (while watching equity value rocket past $2tn) > predict you will soon create a "country of geniuses in a data center", warn that half of entry level white collar jobs will vanish, and sell the dream of curing cancer > have your staff call it presumptuous to expect your company to make money > meanwhile have your company buy back your shares above fair value, then sell again in a second tender and into the IPO > pledge 80% to charity, which your own s1 calls "voluntary, revocable" and "not legally binding" > keep a fixed 50.1% of the votes through one share, even after selling 98% > help pick the trustees who pick the board > park 5% of the company in a "public benefit fund" you co-run > have shareholders cover the private jet for personal use > call it a public benefit corporation anyway

BREAKING: Microsoft, $MSFT, is offering buyouts to 60,000 workers as part of the company’s efforts to cut costs amid AI adoption, per Bloomberg. Personnel on select teams in the US, Canada, India, and the UK at a vice president level and below will be eligible. This reflects ~27% of Microsoft's total workforce.

Not mentioned: duration risk. Short term revenues Longer term compute contracts Everything is fine as long as demand for compute outstrips supply of compute. Maybe even better than fine, if prices are high enough on secondary markets. You just sell excess capacity to the market. But what happens when we reach supply-demand equilibrium? You’re kind of betting that doesn’t happen until those LTAs are expired. Otherwise… you’re trapped in a bad lease. Honestly, I’m getting REIT vibes and I won’t elaborate.

"The one thing you knew if you ever built a software company is that you cannot throw money at the problem." @bhorowitz wrote The Case for the Fat Startup in 2010, arguing that startups should raise enough money to squash their competition. He leads a firm renowned for pumping founders with cash. Joining @a16z's 2026 Just a Few Billy More fundraising tour, he's back to assure LPs that while this strategy was a failure for SaaS and NFTs, it will work for AI. Despite all the evidence that capital has a convex relationship with success, at every level and in every strategy, this is a noisy return to the "capital as a moat" nonsense of ZIRP. Surely, this has nothing to do with his firm's incentives to raise and deploy as much and as quickly as possible, or the desire to market large pools of capital as advantageous for founders.
Ben Horowitz (@bhorowitz):  The laws of physics of company building changed. You can throw money at problems now. "If you have the data and you have enough GPUs, you can solve damn near anything." Technical moats aren't dead. They're just turning into capital moats. Whoever spends more on data and compute can catch up (or stay ahead). Strong teams that are well capitalized get exponentially more leverage than before.

alright finally through the Anthropic S-1. Great quarter and I love the product, but I don’t like the governance structure, and I don’t know how much I trust Dario et. Al. to be a good steward of my money. In fact, they’re very clear that maximizing returns is not the goal. The demand for compute is creating an interesting dynamic where the LTAs are providing a kind of backstop against model risk… if OAI develops a better model and everyone switches over (again), Anthropic can always sell their spare compute for more than they paid. In fact, that arbitrage is basically the entire business! Anthropic has locked in a bunch of compute (read: commoditized tokens) and is selling those tokens for a profit. So the real test of this company comes when compute prices level off and their arbitrage utility margins compress. Perhaps the sale of the neoclouds was a bit hasty

If you think San Francisco is only 4-5 years behind NYC culturally then you are a philistine idiot. San Francisco is decades behind NYC and anyone with an iota of taste in their body knows this. NYC clears SF in food, night life, music, arts, fashion, urbanism, walkability, intellectual spaces, and exposed brick walls. If you have observed how people in the two cities even just dress and carry themselves you know it's a hydrogen bomb vs coughing baby situation. NYC has comedy clubs, theater, and intellectual life spanning EVERYTHING, not just AI and tech. In New York I can go see a play, get dinner in a dimly lit restaurant, and then get drinks with my friends for like $500. You can't do that in SF. In NYC I can go to a party in Brooklyn and meet amazing experimental visual artists who really don't like getting asked if their parents pay for their nice 1 bedrooms. Yesterday I went bar hopping during the day to catch all the Big 10 football games which is becoming a huge cultural mainstay in Manhattan. Yeah, we're culturally and intellectually superior to San Francisco tech nerds. Do I even need to mention the subway?

I wrote a few weeks ago that Amazon blocking agents would be an opportunity for Walmart. Now Walmart is building an MCP server so agents can shop there directly. Amazon has a huge ($50B+), high-margin ads business to protect. Walmart has a much smaller ecom business, and thousands of physical stores. Walmart also cares about being disintermediated, but even if an agent does the shopping online, people will still walk into Walmart stores to buy things. So Walmart has another way to maintain that relationship with customers, while potentially picking up some of the purchases Amazon is turning away. xitter.cf/jgreze/status/21049883… xitter.cf/TechCrunch/status/2112…
As Amazon blocks AI agents from shopping on its site, Walmart is taking the opposite approach, introducing new technology that lets AI agents make purchases on customers' behalf, with controls over spending and transaction approvals. spr.ly/6019BHXyoW

100%. If you can’t give a high level yes/ no within 10 minutes of meeting a founder and their company, you’re probably allocating in the wrong asset class.
I think the startup world has made fundraising way too much of a full-time job. Founders spend six months pitching 100 VCs, tweaking decks, chasing introductions, and answering the same questions over and over. Then they finally raise $5M, celebrate for a week, and start preparing for the next round. At some point, when do you actually build the company? I’ve seen founders who are incredible at raising money but surprisingly average at running a business. Fundraising is an important skill, but it’s not the business. Your job isn’t to convince investors you’re building something valuable. It’s to actually build something valuable. The best fundraising strategy is having a business investors can’t ignore.

Heard from VC LPs this week. It was our AGM, so I had a ton of convos. Theme is liquidity and differentiation. Some quotes 👇🏻 - “we see a huge difference btw the posture of the GPs who do public + private and those that just do VC/Growth. They are living in different realities.” - “every GP is raising again faster than we thought, either because they just blew through the money, or because they want a war chest for when the market trips over itself” - “Across the top GPs, everyone is in market. TVPIs look amazing - differentiation is DPI, concentration and portfolio mgt” - “We really need the PE guys to start selling some stuff!!” - “If Anthropic IPO goes great, we are worried it sets the bar too high for everyone else. And if it doesn’t go great, then the bar is even higher…”

Fuck your priors! Fantastic interview. Instant follow. I used to wake up for dawn patrol in high school.
New @ThePeelPod with @orenzeev He manages $2.7B across 11 funds with no team. He has no meetings, doesn't write investment memos, and has never shown an LP a single slide from a deck. We get in to the 30-minute conversation that turned into his first fund, why most partners add negative value, the days his calendar is empty enough to surf on a Tuesday, his fund that had only five companies (and why diversification is a lie), how Navan went from a $90M run rate to zero in a month (and survived), why he does cross-fund investing, refusing DPI when LP's want it, and the 30-year history of Israel's startup economy.

Hot take from S.F. compute: “Within the next 6 months, most AI startups will not be able to buy compute. The world’s compute is sold out. To get capacity, you’ll need to sign up for a new cluster. However, it’s becoming increasingly difficult to get capacity online from folks who are not investment grade. Startups are not investment grade.” I hope this is wrong, but I think many entities are unprepared for compute shortages and demand being much higher than what Wall Street expects, and so high demand and high interest rates will cause a big problem for everyone.
