TSMC has fully divested its stake in Arm Holdings, selling approximately 1.11 million shares at US$207.65 each for a total of US$231 million, the company disclosed on April 29, 2026. The transaction generated roughly US$174 million in retained earnings.
TSMC said the sale reflects a strategic adjustment in its financial investment portfolio. The company no longer holds any Arm shares.
TSMC originally bought into Arm at US$51 per share — a total of nearly $100 million for roughly a 0.2% stake — when the SoftBank-owned chip architecture company listed on Nasdaq in September 2023. That IPO drew a who 's-who of the semiconductor industry as anchor investors, including Apple, Nvidia, AMD, Intel, Samsung, Google, and MediaTek. TSMC trimmed its position in February 2024, selling 850,000 shares for about US$102 million, before exiting entirely with this week's transaction.
TSMC said its original investment was aimed at strengthening ties with customers across the chip design and manufacturing ecosystem.
Industry analysts view TSMC's total divestment from Arm as a strategic decoupling. As Arm evolves into a silicon producer with its AGI CPU initiative, it moves into a competitive gray zone with TSMC's other Tier-1 clients. By liquidating its stake at a 3x gain, TSMC not only secures massive liquidity for its 2nm expansion but also restores its position as a strictly neutral foundry partner in the increasingly fractured AI silicon landscape.
