⚠ Three Is Also Small Enough to Coordinate BadlyModerate threat

SK hynix (SKHY) — threat to the moat

The same small number that makes discipline possible makes one participant's misjudgement unsurvivable for the other two.

A three-player market is not merely a smaller version of a thirty-player one. Each participant is large enough that its individual decisions move the whole market — which is how world DRAM revenue fell 36.5% to US$49.9 billion in a single year with only three producers in it1 — which means an error by any one of them is an error for all three.

The same small number that enables discipline makes one error unsurvivable.

If one producer decides to buy share — pricing aggressively to fill a new fab, or to establish a position in a product where it is behind — the other two cannot ignore it. The market is too concentrated for the volume to be absorbed quietly. What in a fragmented industry would be one firm's bad quarter becomes, with three participants, an industry-wide price event.

There is a specific version of this risk right now. A competitor that has lost HBM share and has the balance sheet to fight has an obvious incentive to price for position, and its memory business is a smaller share of a very much larger company.

What restrains it is that all three have lived through 2023 and none enjoyed it.

The number to watch is any producer's bit shipment growth running materially ahead of the other two. Share bought with price is visible in volume before it is visible in margin.
