ASML is the most important company you've never heard of.

The $300B+ Dutch firm makes the machines that make semiconductors. Each one costs $150m and access to them are a huge geopolitical flashpoint.

Here's a breakdown 🧵
1/ What *exactly* does ASML sell?

Its key product is an extreme ultraviolet lithography (EUV) machine, which uses advanced light technology to "print" tiny circuits onto Silicon wafers.

Only ~50 are made a year and ASML has a near monopoly on the machine technology.
2/ You def know ASML's main clients: Intel, Samsung and Taiwan Semiconductor Manufacturing Co. (TSMC).

They need EUV to keep Moore's Law ("# of transistors on microchips doubles every 2 years") alive and continue to advance computing.

Total ASML sales in 2020 = $16B+.
3/ The ASML story begins in 1984, as a joint venture between Dutch conglomerate Philips and an electronics maker called Advanced Semiconductor Materials Int.

The project had a very humble start: it was launched in a shed behind a Philip's building in Eindhoven, Netherlands.
4/ The venture's first product was called the PA 2000 stepper (think a slide projector "projecting" designs on silicon).

For years, the product failed to make headway against leading Japanese competitors (Nikon, Canon) and, in 1990, ASML was spun out as its own company.
5/ ASML scored its 1st hit product in 1991, giving it momentum to IPO in 1995.

Soon after, it acquired a # of US lithography firms and -- by the end of 1990s -- it had comparable market share to Nikon and Canon.

From there, ASML made 2 big bets that separated it from the pack.
6/ Both bets were made to keep up with Moore's law.

First: In 2006, ASML released its TWINSCAN system using immersion lithography (it utilizes water as lens to shrink the laser's wavelength = more circuits on chip).

It was ASML's first market-leading product.
7/ Also in the mid-2000s, ASML started spending huge R&D on EUV technology.

It was a massive risk, though: EUV lithography would require Samsung, Intel and TMSC to completely rebuild and redesign their fabrication plants.

From 2008-14, ASML put $5B+ into EUV research.
8/ The science behind EUV was established in the late 1980s. It was a US-led effort between the Dept. of Energy and industry (e.g. AMD, IBM, Intel).

ASML licensed EUV tech in 1999. Canon elected not to pursue it due to financial problems while Nikon chose to develop older tech.
9/ How EUV works today:

◻️ A tin droplet drops into a vacuum
◻️ It's pulsed by a high-power laser
◻️ Tin atoms are ionized, creating plasma
◻️ A mirror captures EUV radiation emitted by plasma
◻️ Mirror transfers EUV to wafer (wavelength=13.5 nanometers, basically X-ray level)
10/ The potential of EUV was so great that Intel, Samsung and TMSC -- all competitors -- jointly acquired 23% of ASML.

Intel put up the most: €2.5B for a 15% share (today, the firms have sold down most their stakes).

The first production-ready EUV machine was released in 2016.
11/ Why are EUVs so expensive?

ASML plays a role similar to Boeing for airplanes (also $100m+ products): it's an integrator of 4750 global high-value parts suppliers:

◻️ Tooling equipment (US)
◻️ Chemicals (Japan)
◻️ Lens (Germany)

(Nikon/Cannon do most production in-house)
12/ Why can ASML only produce 50 EUV machines a year?

◻️ Co-ordinating 1000s of suppliers is very difficult (just like an aircraft)
◻️ Each machine is custom (30+ variables to choose from)
◻️ Lead-time are long (speciality parts like the Zeiss lens takes 40 weeks to produce)
13/ The delivery process is nuts, too:

◻️ Each EUV weighs 180 tons
◻️ A disassembled EUV takes up 40 shipping containers
◻️ Shipping it (mostly to Asia) takes 20 trucks and 3 Boeing 747s
◻️ ASML teams must be on-the-ground to maintain them
◻️ The min spend to house EUVs is $1B
14/ Today, ASML has a 90% share in semi lithography (EUV and Deep UV).

EUV tailwinds are huge:
◻️ Semi CAPEX >$120B+ in 2021 (similar spend in following years)
◻️ Key sectors (esp. auto AKA Tesla chips) will see growth for years
◻️ Transition to 5nm process requires more EUV
15/ Even if machine sales slow, ASML's business is increasingly shifting to system maintenance, relocation and upgrades.

Over a 20yr lifespan of an ASML machine, services-based sales may reach 50% of the initial machine price (w/ high margins)...across a growing installed base.
16/ With chips needed in everything (data centres, AI, autos, mining), semis are the OIL of the 21st century.

The US has even blocked Dutch exports of EUV-licensed tech to China. As the Tech Cold War heats up, expect to hear more of ASML: the $300B+ giant that started in a shed.
17/ If you enjoyed that, I write threads breaking down tech and business 1-2x a week.

Matt Damon and Ben Affleck on Rogan taking about how Netflix has changed filmmaking.

A major considerations is dealing with distracted viewers. To keep them tuned in, “you re-iterate the plot 3-4x in the dialogue because people are on their phones.”

Then, in action films, you change the ordering of climatic fights.

In traditional action films, you’d have “three set pieces” in every act (I, II, III) and each would “ramp up” (spend the big money on third set piece).

But streaming has to hook viewers within 5 minute, so the incentive is to put a major battle or action sequence much earlier.

Also, the directors have less incentive to make a film look great because so many people watch on laptops and phones.

They do say that streaming allows for more bets on risky projects since the theatre economics are geared towards IP, sequels and super-heroes.

Example: an independent film with a $25m budget would spend $25m on marketing (1:1 ratio). But since it splits box office with the theatre, the film needs to make $100m (1/2 of which is $50m) just to break even.

They’re realistic about the state of film and call it a supply-demand issue. If the demand is for at-home viewing (eg. Netflix 300m+ subs), then filmmaking approach will change to feed the algo.

When there’s demand for theatre, Damon will go team up with Christopher Nolan to make “The Odyssey”.
A similar dynamic is happening to streaming TV shows. The incentives for story arc, dialogue and character types warped thr medium.

The Economist has a great piece on strategy sportsbetting apps use to throttle smart bettors:

▫️Skilled players are “sharps” and given “stake restrictions” if they play too well (bets are capped).

▫️Rest of players called “Square”.

▫️In 2025, 4.3% of active UK accounts had a “stake factor” below the maximum bet allowance of 100%.

▫️Sportsbook will take bets with a profit margin as low as 4.5%.

▫️If they are able to do good “player-profiling” and keep the “sharps” from playing, the profit margin can reach 10-20%.

▫️As important as keeping out “sharps” is hooking “whales”, the deep-pocketed players that are willing to keep playing (and losing) large sums.

▫️Some “whales” are actually “sharps” in disguise, though. They’ll lose a bunch of bets to lull the sportsbook then put down a massive bet when they have an edge.

▫️While there is a risk of a “whale” being a “sharp”, the value of a real “whale” is so high that sportsbook will take the risk

▫️“In March 2024 PointsBet, raised its share of online sports-gambling revenue in New Jersey from 11% to 24% after wooing a single cash-spouting customer away from DraftKings.” (I can confirm that this wasn’t me).

▫️How sportsbook profile players:

> Playing on Mobile is a good sign (where majority of people play)
> Playing on PCs is a bad sign (it’s easier to compare odds and run models)
> E-wallets are a red flag (sportsbooks prefer debit direct deposit that can attach a player to a single account; e-wallet is more anonymized and players can move cash between sportsbook more quickly to shop for the best odds)
> Women bettors are a red flag (most bettors are men and “sharps” often use women to place bets)

▫️First wagers are a major tells (typical bettors go after top leagues — NFL, NBA, EPL — and do so near the start of the game).

▫️Popular bets for “squares”: who will win, scoring margins and how star player will perform (also, they love multi-leg parlays).

▫️“Sharps” go after less popular leagues and place bets as soon as odds are published, when they are most mispriced. They also go after less popular bets such as “pts in Q3” or stats from a random player (“Sharps” rarely do parlays and don’t withdrawal winnings often).

▫️One gambling consultant tells The Economist that “By the time a customer places his first bet, [sportsbooks] are 80-90% certain they know the lifetime value of the account.”

▫️”Sportsbooks look at a player’s ‘closing-line value’ — a measure that compares the odds at which he bets with those available right before a match begins. If it is consistently ahead of the market over his first ten wagers, he is highly likely to beat the book in the long run.”

▫️Sportsbook mathematically monitor players and creates a new risk score every 6-8 hours (risk score = estimate of probability that customers will wind up unprofitable).

▫️E-wallet users, women and bets over $100 are flagged. These suspicious bettors are given 30% of maximum bet (and proven sharps only allowed 1%).

▫️High-skilled players will often get a “beard” to bet on their behalf. Most sportsbooks ban this practice but it is widespread.

▫️Safest “beards” are close friends and relatives because you can mostly rely on them to pay out any winnings. The “beards” try to look like degens (playing at 3am, bet non-stop and doing ridiculous parlays) before placing a winning bet.

▫️The most effective strategy for “sharps” is “whale-flipping”. Find a losing gambler, then ask to put a (likely) large winning bet amongst their pool of guaranteed losers.

▫️Once “sharps” max out the people they can use as “beards”, they tap professional networks called “movers”. These “movers” employ a bunch of “mules” who can put down bets on the behalf of the network. Low-end movers charge 10-20% while high-end movers charge 50% of winnings.

The invention of bánh mì is a combination of climate, trade and urban layout of Saigon in late-19th century designed by French colonist.

When the French captured the area in 1859, most economic activity in the region took place along the Saigon river.

The population built makeshift homes tightly bundled by the river banks. Outgrowth from this eventually lead to narrow alleyways between many buildings that is trademark of the city (the Khmer named the region Prey Nokor then French renamed it Saigon and then it was renamed to Ho Chi Minh City in 1976 after end of Vietnam War).

Over decades, the French created European street grids and built wide Paris-type boulevards in the city to funnel commerce to larger markets (also make the city easier to administer).

It was at these markets that French baguettes were introduced and traded.

Bánh mì bread is known for being flaky and crispy on the outside while fluffier on inside (so god damn good).

Two features of Saigon helped create this texture:

▫️Climate: The heat and humidity in Southeast Asia leads dough to ferment faster, which creates air pockets in bread (light and fluffy).

▫️Ingredient: Wide availability of rice meant locals added rice flour to wheat flour imports (which were quite expensive). Rice flour is more resistant to moisture and creates a drier, crispier crust.

Fast forward to the 1930s: the French-designed street layout is largely complete. Now, the city centre has wide boulevards intersected by countless narrow alleyways.

The design was ideal for street vendor carts. These businesses were inspired by shophosue of colonial architecture to sell all types of goods as chaotic traffic rushed by.

Vietnam has some of the most slapping rice and soup dishes, but many people on the move in the mornings wanted something more portable and edible by hand.

Bánh mì was traditionally upper class fare but it met the need for on-the-go food.

Just fill the bread with some Vietnamese ingredients (braised pork, pickled vegetable, Vietnamese coriander, chilies) along with French goodies (pate).

Pair it with cà phê sữa đá (aka coffee with condensed milk aka caffeinated crack) and you’re laughing.Image

Haven’t lived in Saigon for 10+ years but ate a banh mi every other day when I did.

While there, I also sold a comedy script to Fox (pitch: “The Fugitive meets Harold & Kumar set in Southeast Asia”).

It never got made but fun story to retell: readtrung.com/p/im-making-a-…
