Taiwan's stock market jumped on Tuesday in heavy trading, good news for investors riding the chip boom.

• The main Taipei index rose nearly 2%, with turnover topping NT$1 trillion.
• Chip-related names drove the gains, keeping Taiwan's market close to record territory.
• Nvidia put $3.5 billion into MediaTek's record $3.9 billion bond sale, a strong vote of confidence in Taiwan's chip supply chain.
• Higher costs are showing up elsewhere: Taiwan's airlines are raising international fuel surcharges from Sept. 7.

Outlook: Taiwan's market should keep tracking global AI and chip demand, with Nvidia's spending the main thing to watch.
