Taiwan's market capitalisation has passed USD $5 trillion, the Taiwan Stock Exchange said, adding that the milestone was reached at the end of May.
The exchange attributed the rise to investor demand for companies linked to artificial intelligence, semiconductors and related technology sectors. It expects nearly 40 companies to apply for listings this year, including more than 15 from the AI supply chain.
The figures highlight Taiwan's growing weight in global equity markets as international investors seek exposure to AI infrastructure and chip production. Taiwan holds a central position in both industries through its concentration of manufacturers, designers and systems companies.
Foreign participation remains high. At the end of April, overseas investors represented 49.4% of total market capitalisation and accounted for about 35.5% of average daily trading value, according to the exchange.
Technology shares dominate the market. According to the exchange, 81.44% of total market value is in technology-related sectors, giving investors broad access to companies across the AI supply chain, from chip design and semiconductor manufacturing to systems integration and software-led applications.
Listing pipeline
Recent fundraising data point to strong issuance activity and rising valuations. In 2025, IPO applications reached 45 companies, the highest level since 2008, while total fundraising rose to about USD $27 billion, nearly double the level a year earlier and a record for the market.
New entrants have included companies linked to the semiconductor and AI supply chain, such as Hon Precision and V5 Technologies, as well as healthcare and life sciences groups including HCmed Innovations and Heron Neutron Medical. The mix suggests investors are backing not only core computing infrastructure but also sectors that may benefit from wider adoption of advanced computing.
The exchange is also trying to broaden investor attention beyond the market's largest names. It cited programmes such as Power Up Plan 2.0 and the Taiwan Pristine Stock Index as efforts to raise the profile of smaller growth companies.
Global capital
The Taiwan Stock Exchange has also expanded measures to link local issuers with overseas capital. These include cross-border product cooperation, such as the Taiwan-Japan ETF collaboration, and the IR Engage Platform, which helps coordinate meetings with institutional investors and distribute company information.
For issuers, support extends beyond the listing process, the exchange said. It highlighted work on governance, internal controls, financial management and disclosure, all of which can affect how investors assess listed companies and how easily they attract long-term capital.
Sustainability reporting has become another part of that push. The exchange provides an ESG disclosure platform, an information hub and reporting support, alongside net-zero advisory services and carbon-credit matching work with the Taiwan Carbon Solution Exchange.
That reflects a broader trend in Asian capital markets, where exchanges are trying to attract global funds by improving disclosure standards and expanding the tools companies can use to reach investors. Taiwan's pitch rests on its concentration of technology businesses and the strategic importance of its semiconductor sector.
Sherman Lin, Chairman & CEO of TWSE, made that case in direct terms. "TWSE is more than an exchange; it's a glimpse into the future powered by AI. At the intersection of capital and innovation, TWSE is where global capital connects to the companies building the real-world backbone of AI, and where innovation moves from lab to investable growth. With TWSE, engineering can turn AI into reality, and capital can turn that reality into a global industry," Lin said.
The exchange operates listing, trading, settlement and market surveillance in Taiwan's securities market. Its latest figures show how closely its fortunes are tied to the global race for exposure to AI and advanced semiconductor production, with technology-related sectors accounting for more than four-fifths of total market value.
