TSMC’s Q2 2026 gross margin guidance of 65.5-67.5% at a 31.7 USD/NTD rate sets the baseline, yet Polymarket’s tightly clustered odds around 67-70% reflect trader bets on upside from elevated capacity utilization and productivity gains in advanced nodes. Q1’s 66.2% result beat expectations on stronger-than-anticipated loading and cost controls, with 3 nm and 7 nm processes driving 74% of wafer revenue. Offsetting factors include modest dilution from Arizona and other overseas fabs plus higher input costs amid geopolitical tensions. AI accelerator demand continues to support pricing power, but currency swings and the pace of 2 nm ramp preparations introduce the main variables that could shift the final print within or outside the guided range before July reporting.
