Strong semiconductor and AI-related exports have propelled South Korea’s growth momentum into Q3 2026, with September shipments surging 83.5% year-over-year and driving broad upward revisions to full-year forecasts, including the IMF’s recent lift to 3.3%. Q2 GDP expanded 3.7% YoY, yet Q3 data may reflect some moderation amid softer domestic consumption, persistent inflation near 2.9%, and uneven labor-market gains. Trader sentiment on Polymarket remains closely balanced between the 2.5–2.9% and 3.0–3.4% brackets because the advance GDP release on October 27 will clarify whether the export-led rebound sustains above 3% or eases into the mid-2% range, with oil-price pressures and global demand risks as key swing factors.
