@unusual_whales Are any of these named orgs breaking the law? Or are they simply following existing tax legislation, set in place by members of congress?

I can’t listen while I’m distracted by a purple head blemish stuck on a shiny dome without explanation. Is it to hide something ugly? Does it keep the contents from spilling? If that’s the case I think the mouth should also be taped. The redhead acts like any of this BS matters.

After redefining premium travel, we’re raising the bar again – coming soon on our new A350-1000s. The only U.S. airline flying them. This means: 💺 all-new Delta One suites with 3+ inch longer beds 📺 our largest screens yet (24” in Delta One) 🔌 outlets and Bluetooth at every seat 🍹a refreshment station for snacks and drinks 😌 and more room to stretch in every cabin But that’s not all. More of our fleet are getting a glow up, starting with the A330s. All part of how we’re investing in a better experience for you ✈️

I honestly thought this map was made up Hundreds of supertankers, the kind that carry two million barrels each, are currently racing toward the US Gulf Coast from every direction. Atlantic, Indian Ocean, around Africa, the scenic route, the "we were heading to Saudi Arabia but NVM" route. Iran closed the Strait of Hormuz and everyone panicked. Oil hit $126 a barrel. Gas hit $4 a gallon. Cable news did the thing where they put a red banner on screen and say "CRISIS" in a font that suggests you should be hoarding toilet paper. And then something happened that nobody in media seems interested in reporting, for obvious reasons. The world just... switched suppliers? Like changing your internet provider except the internet provider is the entire effing global energy economy. American oil exports are approaching record levels. Gulf Coast refineries are running at 95% capacity. Supertankers that were mid-ocean on their way to the Persian Gulf literally turned around and headed to Texas. That's not a metaphor. Ship tracking data shows them doing U-turns in the Indian Ocean. Meanwhile China, which was getting 45% of its oil imports through Hormuz and paying basement prices for sanctioned Iranian crude, is now competing with Japan and Europe for the same expensive American barrels. Chinese manufacturers are already raising prices 20% on goods headed to the US. So to summarize: Iran played its biggest card and the main result is that the United States became the world's emergency gas station and China's cheap energy subsidy evaporated. This is either the most elaborate coincidence in the history of geopolitics... or someone planned the sequence Venezuela -> Iran -> profits! I'll let you figure out which one

@IdWalkThat @HealthRanger @Knesix Good question… I’m guessing that oil tankers full of oil wouldn’t be heading to the US to unload when the US is only selling… But I might be wrong.

@HealthRanger @Knesix I’m probably being stupid - but the original post specifically shows empty oil tankers heading to the gulf to presumably fill up. Your post is a really cool snapshot of all commercial shipping. Not comparable. Where did I go wrong?

This is incredible. Something is going on in the UK. The Home Office just changed its policy of arresting people for speech crimes, and not only that, it is directly addressing the grooming gang scandal in regards to ethnicity, religion, and cultural backgrounds. Why now? They’ve been denying that they did anything wrong for the longest period of time.

@birdabo My bet - there’ll be so many “permission” and “approval” and “confirm” steps for every single AI interaction via Siri (for our ‘safety’) that no one will actually bother.

Apple just turned Siri into a wrapper. the most genius business move in AI this year. iOS 27 will lets us use claude, gemini, grok, perplexity, and more through Siri. install the app, toggle it on in settings. they spent years trying to make Siri compete. they couldn’t. so they turned the iPhone into an AI marketplace instead. every AI company now fights for a slot on 2.5 billion devices. Apple takes 30% of every subscription. no models to train. no data centers to build. no compute costs. just distribution. the middleman always win. the company that lost the AI race just figured out how to tax everyone lmao.

Starlink in flight Wi-Fi review: "I just tried Starlink Wi-Fi on United — and I can't believe they're not charging for this. This is a game changer. The experience itself was surprisingly seamless. Once I logged in on my phone, I used a QR code to connect my laptop instantly, because yes you can connect unlimited devices. I even uploaded a 40-second TikTok, something I’ve never attempted mid-flight because it usually requires leaving the app open and hoping it doesn’t fail. With Starlink, it took about five minutes and worked on the first try. I can guarantee I’ll notice the difference the next time I fly without Wi-Fi like I experienced on this flight."

@dangainor @nihalmehta @BillAckman @EniacVC @TechNYC Opinion on this opinion: If enough new Florida residents orginally supported the policies that helped degrade the place from which they escaped, and then (idealogically stuck) continue to vote the same way in Florida, they will simply replicate what they just fled.

@nihalmehta @BillAckman @EniacVC @TechNYC I support New York committing suicide. Every leftist, Marxist act of stupidity should be embraced. I want Wall Street to move to Florida. I want every major company and every rich person to leave the state. I want people to see what they voted for.

New York is about to make a massive mistake. The NY State Senate is advancing a proposal to decouple from federal QSBS (Section 1202) — the tax provision that lets startup founders exclude gains on qualifying exits. If this passes, founders would owe 10-13% in combined state and city tax on exits that are tax-free at the federal level and in nearly every other major tech state. Even worse: it's retroactive to January 1, 2025. This comes right as the federal government just expanded QSBS benefits and New Jersey moved to full conformity. New York wants to go in the opposite direction. As a seed investor in NYC who has backed hundreds of companies, I can tell you: founders are mobile. If New York becomes one of the most punitive states for startup exits, the best founders will simply build somewhere else — and the jobs, tax revenue, and innovation will follow. NYC has built something special over the last two decades. This proposal puts it all at risk for a short-sighted revenue grab. If you're a founder, investor, or anyone who cares about the NYC tech ecosystem — please sign the TechNYC open letter before Monday below 👇🏾👇🏾👇🏾 Keep building, NYC 🗽

I plan to buy and deploy large fleets around the country when possible. Should pay back and be positive FCF < 2 years…
Teslaconomics@Teslaconomics

I plan on owning my own Tesla Robotaxi fleet one day. And the more I run the numbers, the more I realize this new business could become one of the most powerful income opportunities I've ever seen. This is how I'm thinking about it. Based on many analyst models and Tesla’s long-term vision, a reasonable base case assumption is about ~$30,000 per year in net profit per Robotaxi to the owner. This is after things like Tesla’s platform fee, charging, tires, maintenance, insurance, and cleaning. Of course, the network is still early and Tesla is just beginning to roll this out in pilot programs in a few cities, so there’s no official real-world owner earnings yet... but using reasonable assumptions around utilization, pricing per mile, and operating costs, the math starts to get really interesting. If one Robotaxi can earn around $30,000 per year, here’s what a fleet might look like: • $100,000 per year → about 4 Robotaxis • $500,000 per year → about 17 Robotaxis • $1,000,000 per year → about 34 Robotaxis It may sound a bit crazy at first, but when you break it down, it starts to make more sense. These vehicles could potentially drive 50,000 to 100,000+ miles per year in high demand areas. If the economics land somewhere around $0.25-$0.50 profit per mile after all costs, you end up right around that ~$30k per vehicle per year range. And remember, the Tesla’s Robotaxi network is going to work a lot like Airbnb for cars. You add your vehicle to the network, Tesla handles the software, routing, payments, and rider experience, and they take a platform fee (often modeled around 25-35%). The owner keeps the rest after operating costs. Another thing that makes this interesting is the expected cost of the vehicles themselves. Tesla has talked about the purpose-built Cybercabs costing roughly $25k-$30k and Elon told me production is starting in 1 month! If that’s even close to reality, a fleet capable of generating around $1 million per year could theoretically cost somewhere around $850k-$1M in vehicles. That ROI is pretty freakin good! Now to be clear, none of this is guaranteed. I'm just thinking out loud and sharing it with you... a lot still depends on regulations, how fast unsupervised FSD scales, demand in each city, insurance costs, and how Tesla structures the network. But if the system works the way Elon has described it for years, owning a Robotaxi fleet could become one of the most powerful forms of passive income I've ever seen. And I plan on sharing the numbers with everyone on 𝕏 when the day comes. Personally, that’s why I’m paying such close attention. Bc one day, owning a fleet of autonomous Teslas working for me 24/7 might be the modern version of owning a rental property, except instead of tenants, you’ve got robots driving people around all day while you sleep. This next book of Tesla is going to be so exciting!
