It looks like the chip shortage is going to last longer than expected. At the beginning of this year, it looked like the chip shortage might be over by early to mid-2027. That no longer seems to be the expectation.
As a reminder of the issue, the chip shortage has come about due to chip manufacturers migrating to produce the more profitable chips used by AI data centers. Recent predictions are that 70% of all memory chips manufactured worldwide will go to data centers for the rest of 2026 into 2027. To put that number into perspective, the first public AI model was introduced to the world in November 2022, and the demand for AI chips has grown since then. At that time, about 32% of chips went to the more traditional data centers used for cloud computing.
Electronics of all types rely on chips known as DRAM (Dynamic Random-Access Memory). A DRAM is comprised of a large number of tiny cells that contain one capacitor and one resistor. The simplicity of the structure makes it relatively easy to affordably manufacture chips in volume. The function of DRAM is to temporarily hold data in storage as the computer uses it, and to dynamically cycle in new data as needed during processing.
Broadband devices like Wi-Fi routers, cable modems, and the core electronics used for fiber and wireless networks use a type of DRAM called DDR4. A few other industries, like automotive and consumer electronics, also rely on DDR4 chips. DDR4 chips have less capacity and are cheaper to make than DDR5 chips used for computers and cellphones. By contrast, AI datacenters use HBM (high-bandwidth memory) chips. These are comprised of a three-dimensional stack of DRAM chips. HBM chips are larger and require more wafer space than normal DRAM, and the manufacturing process is more challenging. At least currently, there is a lot more profit in manufacturing the HBM chips.
Three companies have historically manufactured over 90% of all DRAM chips – SK Hynix Inc., Samsung Electronics Co., Ltd., and Micron Technology, Inc. All three companies have shifted a lot of manufacturing capacity to the HBM chips for AI. Micron fully halted the manufacture of DRAM for personal computers. SK Hynix converted its primary DRAM production line to AI chips in late 2024. DRAM wholesalers are alarmed that the average worldwide DRAM inventory in the supply chain has fallen from a normal 17-week supply in 2024 to a 2-4 week supply currently. All three companies have already pre-sold all of their DRAM capacity for the rest of 2026 and well into 2027.
Unfortunately, there is no short-term relief on the way. Micron is building a new mega-factory in Onondaga, New York, to manufacture DRAM that won’t benefit the supply chain until sometime in 2028. The company is expanding a factory in Taiwan that won’t produce new chips until at least the end of 2027. SK Hynix is investing $13 billion in a new factory in Cheongiu, South Korea, that will be completed at the end of 2027. Samsung is building as new factory in Gyeonngi Province in South Korea that won’t be completed until sometime in 2028.
It doesn’t seem realistic that any other companies will step in to fill the market void because of the complexity and intense quality control needed to make DRAM chips. This means a growing shortage of chips for telecom and other industries for the next two years. A few auto factories have already reduced the number of cars being built due to a lack of chips. For telecom, this is going to result in higher prices and longer waits to get electronics. This also means that ISPs at the bottom of the supply chain, those without the buying power of AT&T or Charter, will see the biggest impacts. Also note that ISPs are going to lose broadband customers who can’t afford to replace a dying computer. As always happens with a big price increase, I can’t imagine that chips will ever return to the old prices. The handful of manufacturers are going to expect higher profits from DRAM than in the past, and due to their monopoly, will be able to charge whatever they want.
