Intel shares climbed 2.25% in European premarket trading, while Arm saw a 3.5% jump following Son’s comments at an annual shareholder meeting in Tokyo. Though Arm’s stock has already tripled this year, Son suggested the company’s current valuation is merely an opening act, projecting a potential tenfold increase in its long-term worth.

Beyond his optimism for Arm, Son highlighted the strategic necessity of Intel’s manufacturing footprint. He argued that tech giants are increasingly seeking to diversify supply chains away from Taiwan Semiconductor Manufacturing Company, positioning Intel as a vital alternative. Son further underscored Intel’s status as a critical national security asset for the United States.

SoftBank maintains significant skin in the game, holding an 86.39% stake in Arm and a 1.73% stake in Intel. Having invested $2 billion in the Santa Clara-based chipmaker as recently as August 2025, Son’s endorsement serves as a direct effort to bolster market confidence in his portfolio’s core semiconductor holdings.
