Nvidia’s exit puts Korean HBM suppliers in focus, but long-term deals offer a buffer

Jensen Huang’s departure raises questions about Nvidia’s future memory-chip purchases, but Samsung and SK hynix have substantial long-term commitments and demand from other AI-chip makers to cushion the uncertainty. The Korean chipmakers’ exposure shows how a leadership change at an AI giant can ripple through the hardware supply chain, without making a sudden collapse in demand the obvious outcome.

NVIDIA Watch analysis

What happened

The Korea JoongAng Daily reports that Huang resigned from Nvidia and that CFO Colette Kress became interim CEO. The article says Samsung and SK hynix have invested heavily in high-bandwidth memory production for Nvidia, but argues that existing supply agreements are unlikely to take a major hit. The uncertainty lies more in Nvidia’s future orders and investment plans.

The report cites Daishin Securities estimates that SK hynix will supply 55% of Nvidia’s HBM4 this year, Samsung 28% and Micron 17%. It also says SK hynix’s DRAM and HBM capacity through 2029 is effectively sold out under customer commitments, while Samsung says its 2027 HBM capacity is booked. Both companies have multiyear agreements with customers beyond Nvidia.

Why it matters

HBM is a key component in AI processors, so changes in Nvidia’s purchasing could matter well beyond one company’s order book. But other firms building their own AI accelerators also need memory. The article’s argument is that a shift in chip demand could leave memory suppliers selling to a broader customer base, rather than simply selling less.

That is a plausible buffer, not a guarantee. The report also notes that Nvidia remains the leading AI-accelerator supplier, with a software and hardware ecosystem that competitors have struggled to match. The balance between Nvidia’s future demand and other buyers’ orders will matter more than boardroom drama alone.

Our read

This is a useful supply-chain question, not a reason to declare an AI-chip shortage over or an Nvidia-shaped hole in the market. Long-term deals give Samsung and SK hynix some visibility; the wider AI build-out may give them more customers. The interesting test is whether that second source of demand grows enough to give suppliers more leverage, rather than just a longer list of things to worry about.

What to watch

• What Nvidia’s next leadership team says about AI investment and memory purchases.
• Whether Samsung and SK hynix turn their wider customer commitments into durable demand.
• How Nvidia’s HBM4 supplier mix compares with the estimates cited in the report.

Discussion spark: If AI-chip demand shifts away from Nvidia, will HBM suppliers gain stronger bargaining power, or will Nvidia’s scale still set the terms?
