When it rains, when the night runs late, or for no particular reason at all, we set a pot of water on the stove. We wait for it to boil, then drop in the noodles and the red soup base. A moment later a familiar smell fills the kitchen. That the smell is, more often than not, the smell of Shin Ramyun is something we never bother to register. To Koreans, ramen is, to a considerable degree, simply Shin Ramyun. Even when we eat some other ramen, we tend to perceive it as ‘ramen that is not Shin Ramyun.’ There is one reference point, and everything else is described by its distance from it.
The oligopolies so far had fairly solid walls. Tariffs kept newcomers out of sugar, cold logistics out of beer, brand value out of apartments. Ramen is an oligopoly too. But this wall has one feature the others lacked: it is lower than you'd think. And inside a low wall, astonishing things happen from time to time.
The Wall of the National Standard
More than half of the domestic ramen market belongs to Nongshim. Shin Ramyun alone has a purchase penetration above 34%, and adding Chapagetti, Neoguri, and Ansungtangmyun brings the penetration of Nongshim's brands to 52%. More than one household in two puts Nongshim in its shopping basket. Shin Ramyun took first place in the ramen market in 1991 and has held it for 35 years; in the 40 years since launch it has piled up 20 trillion won in cumulative sales and 42.5 billion packs sold. Enough to hand a few to every citizen of a fair-sized country.
This wall was built out of taste. The human tongue rarely betrays the flavors it was trained on young. For most of us, the ‘standard for spicy ramen’ is that Shin Ramyun taste, and however delicious a new ramen may be, it starts out in the position of being compared against the standard. To become the standard is to own the rules of the competition itself. Nongshim has held those rules for 35 years.
| Company | Flagship brand | Domestic position / 2025 |
|---|
| Nongshim | Shin Ramyun · Chapagetti · Neoguri | Unshaken no. 1 · revenue 3.51 trillion · operating profit 183.9 billion won (+12.8%) |
| Ottogi | Jin Ramen | No. 2 · revenue 3.67 trillion · operating profit 177.3 billion won (-20.2%) |
| Samyang Foods | Buldak | Lower tier at home · revenue 2.35 trillion · operating profit 524.2 billion won (81% overseas) |
| Paldo | Bibim Myun | Niche · seasonal sales |
One Spicy Flavor That Flipped the Standings
And here a scene appears that the earlier oligopoly stories almost never offered. Samyang Foods — whose domestic share doesn't come to even half of Nongshim's — overtook Nongshim in 2025 operating profit. Not because Nongshim did badly. Nongshim's 2025 revenue was 3.5143 trillion won (+2.2%), its operating profit grew 12.8% to 183.9 billion won, and its domestic operating profit alone jumped 62.6%. But Samyang Foods' 2025 revenue was 2.3518 trillion won (+36.1%), its operating profit 524.2 billion won (+52.1%). An operating margin of 22.3%. For a ramen company, the numbers feel slightly unreal.
The secret lies in a single spicy flavor: Buldak. Long stuck around perennial third place at home, Samyang Foods broke through to the outside world with this scorching-black stir-fried noodle. Buldak now sells in more than 100 countries, and 81% of Samyang Foods' revenue comes from overseas. A company that lived in Shin Ramyun's shade at home stands, beyond the border, with an entirely different face. In the semiconductor story earlier, I described the scene in which SK hynix, the eternal number two, passed Samsung Electronics in operating profit on the strength of HBM alone. The very same thing happened in ramen. Only with a jet-black stir-fried noodle instead of a fiery red broth.
What made this possible is that ramen's wall is low. No tariff, no cold chain, no decades of brand trust is absolute here. Let one new flavor seize people's tongues, and the standings flip more easily than you'd expect. What almost never happens inside the walls of sugar and apartments does happen inside the wall of ramen. This most common and cheapest of goods turns out to be the most dynamic oligopoly of them all.
When the Walls Close In, Go Outside
Samyang Foods' mutiny has, in fact, a larger backdrop: the space inside the wall is shrinking. The domestic ramen market hovers around 3 trillion won and barely grows. The population is falling, and the things people eat have multiplied. However hard you fight over the standings inside, the vessel itself will not widen. So, as if by prior agreement, the ramen companies turned their eyes beyond the wall.
The results are remarkable. In 2025, K-ramen exports crossed 2 trillion won for the first time ever. On top of a 3-trillion domestic market, 2 trillion in exports — the board itself has grown whole sizes larger. Samyang Foods already earns most of its revenue abroad, and even Nongshim, keeper of the national standard, now treats North America and China as its real battlefield. The broth once divided inside the wall now sells across borders. The amusing part is that whether you were first or third inside the wall matters very little outside it. Out there, entirely different rules and entirely different palates are waiting.
The Broth Is Hot, the Wallet Lukewarm
The circumstances of the people who make ramen, though, run at a somewhat different temperature from ramen's popularity.
| Company | Employees | Average annual pay | Average tenure | Revenue per employee | Operating profit per employee |
|---|
| Nongshim | 5,501 | 65.07 million won | 11.1 years | separate 500 million won | ~24 million won |
| Ottogi | 3,388 | 51.71 million won | 9.6 years | 880 million won | ~26 million won |
| Samyang Foods | 3,025 | 56.3 million won | 4.4 years | 630 million won | ~160 million won |
Basis: FY2025 (2025-12-31) annual report employee data; revenue and operating profit per employee on a separate (non-consolidated) financial statement basis.
Average pay at the three companies runs in the 50-to-60-million-won range — toward the low end among the companies that have appeared in this series. Samyang Foods is the especially interesting case. Average tenure: 4.4 years. The speed of the upset is stamped right there in the speed of the hiring — it means the company added that many people within just a few years. And its operating profit per employee is 160 million won, already six times Nongshim's. Yet its average pay still sits in the 50-million range. A company's jackpot and its employees' wallets part ways more often than you'd think.
The next story runs a little against the grain of everything so far. Up to now we have looked only at real walls. This time I mean to examine something that looks like a wall but isn't one. A company that makes a product all by itself in this country — and still cannot be called a monopoly. We go looking for the true face of the lookalike monopoly.
