Samsung Accelerates HBM4 Chip Development in High-Stakes Race Against SK Hynix
Samsung just fired the latest shot in the memory wars—and it's aimed straight at SK Hynix's HBM throne.
The HBM Arms Race Heats Up
While the broader tech sector obsesses over AI models, the real battle is happening several layers down. High Bandwidth Memory isn't just another component; it's the throttle on the entire AI engine. Whoever controls the supply controls the speed of innovation. Samsung's aggressive push into HBM4 development isn't about making a better chip—it's about dictating the terms of the next computing era.
Manufacturing Muscle vs. Market Momentum
SK Hynix grabbed the early lead, locking in deals with the biggest names in silicon. But Samsung isn't playing for second place. The company is leveraging its colossal manufacturing scale and vertical integration to close the gap. This isn't a sprint; it's a war of attrition where production yields and supply chain dominance will decide the winner. The market's betting on the incumbent, but never count out the sheer brute force of Samsung's fabrication might.
The Ripple Effect Beyond Memory
This fight stretches far beyond two Korean giants. Every major AI player—from NVIDIA to the hyperscalers—is watching with bated breath. A true, competitive HBM market means better pricing, faster innovation cycles, and more reliable supply. For the AI industry, that's the difference between exponential growth and hitting a hardware wall. The outcome of this duel will shape chip architectures for the next decade.
Finance's Cynical Take
Wall Street analysts are already modeling the revenue impact, proving once again that finance can turn a cutting-edge technological showdown into a bland spreadsheet—missing the forest for the meticulously forecasted trees.
The clock is ticking. Samsung's move ensures the HBM battle will be fought at a blistering pace, with the winner taking far more than just market share.
Samsung expands foundry and signs $16.5B Tesla chip deal
Samsung is also stacking wins in its foundry business. Jun said new chip deals with major clients have put this part of the company in a strong spot. He claimed the foundry is now “primed for a great leap forward.” One of those big deals is a $16.5 billion agreement with Tesla, signed last July.
Another Samsung co-CEO, TM Roh, gave his own outlook for 2026 and pointed to rising component costs and tariff walls as real threats. He also talked about reducing risks by changing how and where the company sources parts and ships products.
Across Asia, markets opened strong for the new year. South Korea’s Kosdaq ROSE 2.17%, closing at 945.57. The KOSPI Index ended at 4,309.63, up 2.27%. Hong Kong’s Hang Seng rose 2.76% to 26,338.47, and India’s Nifty 50 climbed 0.49% to 26,274.90. Australia’s S&P/ASX 200 closed at 8,727.80, up 0.15%.
Some Asian exchanges stayed shut for the holidays, including Japan and mainland China. Singapore’s Straits Times Index was up 0.32%, while the Sensex in India gained 0.56%. Meanwhile, Sapphire Foods dropped as much as 6.4% after revealing a merger plan with rival franchisee Devyani, before cutting back losses.
SK Hynix warns of harder fight in 2026 as demand for AI chips grows
Over at SK Hynix, CEO Kwak Noh-Jung said demand for AI-related chips had exploded faster than the company expected. Speaking in his own New Year address, Kwak said: “AI demand is now a given rather than an upside surprise.”
He also warned the business climate in 2026 could get worse, not better. According to him, tougher conditions are ahead, and competing in the memory business will demand bolder bets and more spending. His company is leading the HBM market for now, with a 53% share in the third quarter of 2025. Samsung is second at 35%, and Micron is far behind with 11%, based on fresh numbers from Counterpoint Research.
On the first trading day of 2026, Samsung shares jumped 7.2%, while SK Hynix went up 4%. That’s stronger than the KOSPI Index, which only rose 2.3%. Both companies hit record highs. It’s clear the market still sees plenty of money in the memory race, even with the risks piling up.
Some Asian markets were still closed for the holidays, including Japan and mainland China.
