What Consolidation Actually BoughtNarrow moat

SK hynix (SKHY) — moat facet

Oligopoly does not confer pricing power; it shortens the downturns, which over a full cycle is worth considerably more.

It is worth being exact about what an oligopoly gives a commodity producer, because the popular version is wrong. Three DRAM makers holding more than 90% of revenue1 does not let SK hynix set prices. Memory is still sold into a market that clears, and in 2023 that market cleared well below cost2.

World DRAM market revenue, US$ billion$78.7B2022$49.9B2023$91.6B2024$146.9B2025Gartner, June 2026: -15.4%, then -36.5%, then +82.7%, then +60.0%.
Consolidation did not stop the fall. It shortened it.

What consolidation buys is the ability to affect supply. When three producers cut output, supply actually falls and price responds within a quarter or two. When thirty producers cut, nothing happens, because each cut is too small to matter and every producer knows it, so none of them cuts at all. The 1990s memory industry was the second case, and it destroyed a generation of capital.

The practical consequence is that downturns are now shorter rather than absent. SK hynix went from a ₩9.1 trillion loss in 2023 to a ₩19.8 trillion profit in 20243. That whiplash is only possible in a concentrated industry; a fragmented one takes years to clear inventory.

For an owner the implication is about holding period rather than safety. Memory losses have become survivable events rather than existential ones, which is a real improvement and not the same as a moat.

Watch the industry's aggregate capex as a share of revenue. Discipline is a spending decision before it is a pricing outcome.

Moat trajectory: Holding steady

The three-player structure is intact and there is no sign of it becoming a two- or four-player one at the leading edge. What it buys — shorter downturns rather than pricing power — is unchanged.

The number that tests this moat
Reported
DRAM revenue, latest quarter
₩57.0tn in Q2 2026, from ₩17.1tn a year earlier (+233%)

What three producers buy is pricing that moves with their capacity decisions. DRAM revenue falling faster than bits shipped would mean the discipline has broken.

⚠ Threats to the moat
⚠ THREAT 01
Three Is Also Small Enough to Coordinate Badly
The same small number that makes discipline possible makes one participant's misjudgement unsurvivable for the other two.
