Bernstein Says Memory Bull Market to Last Until 2027 as AI Demand Rewrites the Cycle

Bernstein just reset the clock on the memory market. Analysts Gautam Chhugani and Mahika Sapra argue the current bull run in DRAM and HBM won’t peak until 2027, breaking the traditional four-year cycle. The call isn’t about hype. It’s about structural supply, long-term agreements, and an AI build-out that keeps eating memory faster than fabs can ship it.

Why 2027 looks different
Historically, memory flipped every 18 to 24 months. Oversupply killed pricing, margins collapsed, and stocks reset. This time, three forces are changing the math:
1. HBM scarcity: High-bandwidth memory for AI GPUs is sold out through 2026. Bernstein expects 2 to 2.5 times year-over-year increases in HBM average selling prices heading into 2027, spanning HBM3, HBM3E, and the incoming HBM4. Jefferies models 40 to 50 percent quarter-over-quarter gains in Q3 2026 alone, with peak ASP near $2.23 per GB by 2027. 2. Long-term agreements: Roughly 35 percent of total bits for FY27-29 are already under LTAs at a contracted $0.26 per GB, only 10 percent below spot forecasts. That puts a price floor near current levels and dampens the old boom-bust pattern. Hyperscalers are signing multi-year deals to secure supply, giving SK Hynix, Samsung, and Micron visibility they never had. 3. Capex reality: Fabs take years. Micron’s $200 billion build-out, SK Hynix’s Yongin cluster, and Samsung’s Pyeongtaek expansion won’t meaningfully add bits until late 2027. Meanwhile, AI training clusters are doubling every 6 to 9 months. Demand is growing into a wall.
Who benefits
Bernstein raised targets across the space. SK Hynix holds 62 percent HBM share and has removed price caps on 2027 contracts, shifting pricing power to suppliers. Micron is sold out of HBM3E through 2026 and just guided margins higher. Samsung is catching up on HBM3E qualification and still dominates commodity DRAM, where spot prices are now rising after two years of pain. Equipment names like ASML see order books stretching to 2027 because EUV layers per HBM stack keep climbing. Power and cooling suppliers like Infineon benefit as AI racks pull more watts per GPU.

What could break the thesis
The risk isn’t demand disappearing. It’s supply arriving faster than expected or AI budgets pausing. China’s domestic HBM efforts, potential export shifts, and a macro slowdown could cool orders. Still, Bernstein’s point is that even at the cycle peak, the floor is higher than any prior top. The downcycle, if it comes, starts from $0.26 per GB, not $0.08.

Market takeaway
Memory stocks have already moved. SK Hynix is up eightfold in 2026, Micron hit new highs, and ETF flows are broadening beyond Bitcoin into semis and infrastructure. Bernstein sees trading volumes peaking in 2027, with earnings growth into 2026 and multiple expansion as investors re-rate memory from cyclical to secular.

For portfolio positioning, the message is clear: AI isn’t just about GPUs. The memory behind them is booked, repriced, and contracted for years. If Bernstein is right, the bull market in bits runs until 2027, and the companies that control those bits keep the pricing power.
