Samsung’s quarterly profit just topped 100 trillion won. The AI memory boom paid for it

Samsung Electronics said on October 8 that it expects third-quarter operating profit of 107.4 trillion won, roughly $80 billion depending on the exchange rate used, the first time the company has cleared 100 trillion won in a single quarter. The preliminary estimate puts revenue at 195 trillion won.

The scale of the jump is striking even by the standards of the AI boom. Operating profit rose 783% from the same quarter a year earlier, and revenue rose 127%. Compared with the previous quarter, operating profit grew 20.1% and revenue 14%.

Memory is the whole story

The company did not break out results by division in its preliminary figures, but analysts attribute the surge to memory chips. Demand for server DRAM and high-bandwidth memory, the stacked chips that sit next to AI accelerators, has climbed as technology companies keep pouring money into AI data centers. Tight supply has pushed memory prices sharply higher, and Samsung, the world’s largest memory maker, captures that pricing directly.

Operating profit came in slightly ahead of analyst expectations of about 106.1 trillion won. Revenue, however, fell short of consensus estimates, a reminder that the profit is being driven more by price than by volume across the whole company.

The other side of the price spike

Higher memory prices are a windfall for the chip business and a cost for everyone who buys memory, including Samsung’s own phone and appliance divisions. Analysts have noted that rising component costs squeeze margins on smartphones and home electronics, and the same pressure runs through PC makers, server buyers and cloud providers.

What it means for businesses

• Budget for pricier hardware. Laptops, phones and servers with more memory are likely to stay expensive while AI demand absorbs supply.
• Do not assume AI tools get cheaper on schedule. Memory is one of the inputs to cloud computing costs. Price AI subscriptions and usage with some headroom.
• Watch the full report. Samsung’s detailed results later in October will show how much came from memory versus phones and displays, and how the company sees demand into 2027.

For investors and operators alike, the figures are the clearest signal yet that the AI buildout is no longer only a story about chip designers. The companies that make the memory those systems depend on are now among its biggest beneficiaries.
