Taiwan Semiconductor (TSM) Stock Rallies on Massive $1.5T Chip Market Projection

Table of Contents TSM shares finished trading at $399.80 on May 13, climbing 0.63% during regular hours, before advancing another 1.55% to $406.00 in after-hours activity. Taiwan Semiconductor Manufacturing Company Limited, TSM Taiwan Semiconductor Manufacturing Company has unveiled a dramatically higher projection for the worldwide semiconductor market, now expecting it to exceed $1.5 trillion by the end of the decade. This represents a substantial 50% increase from the chipmaker’s earlier $1 trillion estimate, with the company unveiling these revised figures just before its annual technology symposium held in Taiwan this Thursday. Artificial intelligence demand serves as the primary catalyst behind this significant upward revision. The foundry giant anticipates that AI and high-performance computing will comprise 55% of the total $1.5 trillion market — translating to approximately $825 billion. Mobile phone applications rank as the second-largest segment at 20%, while automotive chips account for 10%. One metric particularly captures attention: AI accelerator wafer demand is expected to expand elevenfold during the four-year period spanning 2022 to 2026. Such extraordinary growth rates are uncommon in industry projections, and this forecast clarifies why TSMC is pursuing a construction strategy that would have appeared overly ambitious only several years ago. To address this anticipated surge in demand, TSMC has announced it’s accelerating capacity additions throughout 2025 and 2026. The semiconductor manufacturer intends to develop nine distinct phases of wafer fabrication plants and advanced packaging facilities within this year alone. Production capacity for its most sophisticated chips — the 2-nanometer process node and the upcoming A16 technology — is projected to grow at a 70% compound annual rate spanning 2026 through 2028. This figure bears repeating for emphasis. TSMC’s CoWoS packaging methodology, extensively utilized in Nvidia’s artificial intelligence processors, is predicted to expand at an over 80% CAGR between 2022 and 2027. CoWoS technology has emerged as a critical constraint in AI chip manufacturing, and TSMC is unmistakably channeling substantial resources toward addressing this limitation. At TSMC’s Arizona operations, the initial fabrication facility has commenced chip production. The second plant is scheduled to receive manufacturing equipment during the latter half of 2026, while construction proceeds on a third facility. The company has also finalized acquisition of an additional substantial land parcel within the state for future development, with construction on a fourth fab anticipated to commence this year. Production volume from the Arizona manufacturing complex is projected to nearly double year-over-year during 2026, achieving yields that TSMC states will be equivalent to those achieved in Taiwan. Regarding Japan, the first fabrication facility has entered volume manufacturing. Plans for the second Japanese fab have been enhanced to produce 3-nanometer chips rather than the originally planned less advanced process node, addressing stronger-than-anticipated customer demand. In Germany, TSMC’s fabrication plant remains under construction and progressing according to schedule. Initial production will focus on 28nm and 22nm chips before transitioning to more sophisticated 16nm and 12nm manufacturing processes. TSMC’s previous $1 trillion market forecast, now elevated to $1.5 trillion, demonstrates how rapidly the artificial intelligence infrastructure buildout has transformed the economic calculations for the broader semiconductor sector.
