AI boom drives Southern Taiwan Science Park revenue past NT$1.7 trillion in 1H26

NT$1.7 trillion in H1 2026 is not a growth headline — it is a structural repricing signal. The 28.57% YoY surge at Southern Taiwan Science Park reveals that AI compute demand has simultaneously maxed out three supply bottlenecks: CoWoS advanced packaging capacity, HBM stacking yield, and EUV lithography delivery cycles. This is a supply-constrained regime, not a demand-side story. On compliance, CHIPS Act tax credits and BIS export controls operate as a structural hedge: firms in the park capture U.S. subsidies while remaining subject to entity-list restrictions on equipment procurement. Compliance cost has become an embedded margin haircut, not a one-time line item. Competitively, Samsung P4 and Intel Ohio target 2027 production, attempting to replicate STSP ecosystem density. But two decades of foundry-OSAT-EDA co-evolution cannot be replicated by capex alone. The moat is supply-chain response velocity, not wafer output. 12-24 month outlook: AI inference chips will depend on advanced packaging more than on logic node advancement. ABF substrates, glass interposers, and Chiplet interconnect standards will become the next pricing-power battleground.
