Taiwan's biggest company is riding the artificial-intelligence wave to new heights.

According to the Taipei Times, Taiwan's benchmark TAIEX index closed at a new high, soaring more than 1,200 points as contract chipmaker Taiwan Semiconductor Manufacturing Co (TSMC) broke its own closing records. The paper attributed the surge to optimism over global AI demand.

The rally extended to TSMC's US-listed shares. Blockonomi reported that the stock (ticker TSM) climbed 2% to $473.50 after the investment firm Susquehanna raised its price target to $575, citing AI chip demand that continues to exceed supply.

The momentum reflects TSMC's central role in the AI boom. As AD HOC NEWS noted, the company is extending its lead in AI, with its shares benefiting from strong momentum across the chip sector.

TSMC manufactures the advanced processors that power AI systems for many of the world's largest technology firms. When demand for AI hardware outpaces what factories can produce, as the sources describe, it tends to lift both TSMC's business and the broader market that depends on it. That helps explain why a single chipmaker can pull an entire national stock index to a record.

Why it matters: TSMC sits at the heart of the global AI supply chain, so its record run is a signal of just how much money and confidence the world is pouring into artificial intelligence.
