Nvidia GTC Targets $1T AI Inference, HBM4 Supply Realignment — Brent Breaks $103

Investment Implications

Inference Splits in Two. HBM4 Demand Narrows to One.

As Nvidia formalized a two-stage inference architecture at GTC 2026 — while raising its AI inference market forecast to $1 trillion — the question of which supplier captures concentrated HBM4 demand is coming into sharper focus.

At the GTC 2026 keynote, Jensen Huang doubled his AI inference market outlook to $1 trillion by 2027, up from the $500 billion figure he offered in February. The number itself is impressive, but the more important detail is the architecture: inference is now formally split into two stages. Prefill — input processing — goes to the Vera Rubin chip; decode — output generation — goes to Groq chips, acquired last December.

The separation has direct implications for HBM. Prefill demands high-bandwidth HBM to process large matrix operations in a short window. Decode is comparatively less dependent on memory bandwidth. As inference architecture splits, HBM4 demand concentrates on the prefill chip (Vera Rubin). has already been selected to supply roughly two-thirds of the HBM4 required for the Vera Rubin platform. is moving fast — tripling HBM output versus 2025, targeting 50%+ HBM4 share of total HBM production — but holds the first supply allocation for Vera Rubin.

WEF projects AI data center power demand could increase 30x within a decade. As inference rivals training as an HBM demand driver, which supplier you're talking about matters far more. Yesterday's insight traced how AI demand ripples into materials markets (platinum group metals); today we look inside. The architectural split in AI inference is a direct signal reshaping revenue visibility for Korea's memory semiconductor suppliers.

The formalization of prefill/decode separation at the GTC keynote is essentially an uncertainty-clearing event. Worth watching: how quickly the Korea memory semiconductor sector prices this in.

Nvidia Doubles AI Inference Market Forecast to $1T — Prefill/Decode Two-Stage Architecture Formalized

Jensen Huang announced at GTC 2026 that the AI inference market opportunity would reach at least $1 trillion by 2027, doubling the $500 billion figure given in February. He unveiled a two-stage architecture splitting inference into prefill (Vera Rubin chips) and decode (Groq chips), and projected Vera CPU as a standalone business worth "tens of billions or more."

SK Hynix Selected to Supply Two-Thirds of Vera Rubin HBM4 — 2025 Operating Profit Hits Record KRW 47.2T

SK Hynix has been selected to supply roughly two-thirds of the HBM4 chips required for Nvidia's Vera Rubin AI platform. Its 2025 annual operating profit reached a record KRW 47.2T, surpassing Samsung Electronics, with cash and equivalents more than doubling year-over-year to KRW 34.9T. SK Group Chairman Chey Tae-won met directly with CEO Jensen Huang at GTC 2026 to discuss HBM4 supply and AI infrastructure cooperation. (Source: Yonhap News, Yonhap News)

Samsung Triples HBM Output, Unveils First HBM4E Sample

Samsung Electronics formally announced at GTC 2026 it would triple HBM production versus 2025, targeting HBM4 at more than 50% of total HBM output. The company also previewed its first seventh-generation HBM4E sample (16Gbps/pin, 4.0TB/s bandwidth — 23% faster and 21% higher bandwidth than HBM4). CEO Jensen Huang confirmed Samsung Foundry will manufacture the Groq 3 LPU. (Source: Yonhap News)

US EV Registrations Plunge 41% — Market Share Falls from 8.3% to 5.1%

New EV registrations in the US dropped 41% year-over-year in January 2026, with market share falling from 8.3% to 5.1%. The Trump administration's early elimination of EV subsidies and tariff policies are cited as the primary causes. Tesla and LG Energy Solution plan to jointly build a $4.3 billion LFP battery plant in Michigan, targeting production by 2027. (Source: OilPrice)

Iran Blocks Tankers Carrying 20% of World Oil Through Hormuz — Supply Disruption Twice the 1970s Scale

Iran continues to block tankers carrying roughly 20% of global oil supply through the Strait of Hormuz — a supply disruption approximately twice the scale of the 1970s energy shocks. Iraq, which has no viable Hormuz bypass, has cut production from 4.4 million b/d (pre-war) to roughly 1.4 million b/d, and Iraq's oil minister has opened direct negotiations with Iran.

UAE Shah Gas Field Fully Halted — Brent at $103.2, Up 50% Since War Began

In the first direct strike on production facilities rather than processing or storage, Iran has fully halted the UAE's largest sour gas field — the Shah gas field (12.8 billion scf/day, 4.2 million tonnes/year of sulfur). The Abu Dhabi Crude Oil Pipeline (ADCOP, 1.5 million b/d), the UAE's only Hormuz bypass export route, has also sustained repeated strikes, cutting UAE daily crude output by more than half since the war began. Brent crude is at $103.2 (+3%), up 50% from pre-war levels; European wholesale gas is at €52, up 73% from the pre-war level of €30. (Source: The Guardian, CNBC)

Asia Spot LNG Prices Double to 3-Year High — Asia Pivots to Coal Power Expansion

Asia spot LNG prices have doubled to a three-year high — the second supply shock in four years, following Qatar's Hormuz-driven shipping halt. Bangladesh, the Philippines, Thailand, and Vietnam are pivoting to coal power expansion. India, where 50-55% of city gas supply depends on Qatari LNG, is seeing state-owned fuel retailers (IOC, BPCL, HPCL) demand advance payments from dealers due to margin losses.

WTO Fisheries Subsidies Agreement Takes Effect — Harmful Subsidies Banned from $35B Annual Fisheries Support

The WTO Fisheries Subsidies Agreement, which entered into force in September 2025, bans subsidies for illegal, unreported, and unregulated (IUU) fishing and for fishing overstocked species. Of the roughly $35 billion in annual government fisheries subsidies, more than $5.3 billion was spent by the top ten harmful-subsidy countries on fishing in foreign waters as of 2018. China leads at $5.9 billion. (Source: Mongabay)

Everglades Restoration Boosts Carbon Sequestration 18% — Absorbs 14 Million Tonnes CO₂ Annually

The US Everglades restoration project increased carbon sequestration by 18% between 2003 and 2020, now absorbing roughly 14 million tonnes of CO₂ per year. However, approximately 82% of the freshwater wetland's sequestration is offset by net methane emissions — a stark contrast to coastal mangroves (18% offset). This is the first study to highlight the complexity of net greenhouse gas benefits from wetland restoration. (Source: Inside Climate News)

Japan Raises Permanent Residency Fees by 2,900% — Controversy Amid Labor Crisis

Japan's revised immigration law, passed by parliament on March 10, raises permanent residency application fees from ¥10,000 to a maximum of ¥300,000 — a 2,900% increase — and visa renewal fees from ¥6,000 to a maximum of ¥100,000. The intent appears to be screening out low-income migrants, but critics note the contradiction: Japan's working-age population is in structural decline alongside Korea's, and the direction of this policy runs counter to the labor needs of both economies.
