Huawei chip plans spark SMIC jump as LogicFolding targets 1.4nm by 2031
Chinese semiconductor stocks rose in Hong Kong and Shanghai after Huawei unveiled chip-design progress framed as a workaround under US export sanctions. At an IEEE symposium in Shanghai on May 25, Huawei semiconductor president He Tingbo introduced “LogicFolding” and the “Tau Scaling Law,” arguing that systemic architecture optimization can boost performance without relying on extreme-UV lithography.
Huawei said it has already mass-produced 381 chips using the Tau Scaling Law over the past six years. It also confirmed that its Kirin mobile chips incorporating LogicFolding are set to launch this fall.
The market reaction was immediate: SMIC, a key manufacturing partner for Huawei, jumped more than 17% in Shanghai on the news. The backdrop remains heavy: US controls target advanced semiconductor tools (including ASML EUV) and high-end AI chips used for training, where Chinese firms such as DeepSeek and ByteDance have faced sourcing challenges.
Huawei’s “1.4nm-equivalent” performance target is set for 2031, and investors will watch the fall Kirin rollout for measurable real-world results. If Huawei can demonstrate consumer-product gains, the narrative could shift from aspiration to evidence, even as SMIC’s leading process still trails TSMC by several generations.
Key takeaway for traders: Huawei chip plans are driving near-term sentiment in China’s tech supply chain, but the longer-term impact hinges on whether LogicFolding delivers repeatable performance against the sanctions-constrained baseline.
Bullish
The news is broadly bullish for risk sentiment around China’s semiconductor supply chain. Huawei chip plans triggered an immediate, concrete re-pricing of SMIC shares (+17% headline move), showing that traders are treating the LogicFolding/Tau Scaling Law announcement as a potential reduction in China’s dependence on the most advanced Western process tools.
In the short term, expect volatility and momentum flows into China-listed chip makers and AI-adjacent names as traders front-run possible wins from the upcoming Kirin launch. This resembles earlier “export-control workaround” headlines in tech, where markets often overreact initially and then fade unless follow-up benchmarks confirm the story.
In the medium to long term, the bullish case depends on verification. The 1.4nm-equivalent target is for 2031, so near-term price action likely remains headline-driven until the fall Kirin chips provide measurable performance/efficiency data. If results disappoint, momentum could reverse quickly; if results confirm, the theme could support sustained sector bids, improving market stability within the broader tech complex—although geopolitical risk remains a persistent overhang.
