Billionaire Masayoshi Son  Put 66% of Its $18 Billion US Portfolio Into 1 Stock

On August 14, 2026, Masayoshi Son’s SoftBank Group (OTC:SFTBF) disclosed via 13F that it had funneled 66.81% of its disclosed US equity portfolio into a single name: Intel (NASDAQ:INTC | INTC Price Prediction). The position, held as of June 30, 2026, totaled 86,956,522 shares valued at $12,141,739,167. For a fund of SoftBank’s scale, that level of single-stock concentration is a directional bet on an American semiconductor turnaround.

What Son Bought, and Why the Size Matters

The other holdings look almost decorative next to Intel. Symbotic (NASDAQ:SYM) sits at 9.85% ($1.79B) and T-Mobile US (NASDAQ:TMUS) at 9.23% ($1.68B). Everything else, including SoftBank’s fintech basket of Klarna, Chime, eToro, Nu Holdings, and Inter & Co, rounds to noise against the Intel weighting.

Son’s team was not chasing momentum blindly. Recall that SoftBank had already committed a $2.0 billion strategic investment into Intel that closed in Q3 2025, alongside NVIDIA (NASDAQ:NVDA)’s $5.0 billion equity investment. The 13F confirms Son doubled down at scale, buying the recovery story rather than trimming into strength.

The Underlying Thesis

Intel’s operating fundamentals justify at least part of the aggression. Q2 FY2026, reported July 23, 2026, delivered revenue of $16.128 billion, up 25.4% year-over-year, and non-GAAP EPS of $0.42 against a $0.22 estimate. Data Center and AI revenue jumped 59% YoY to $6.262 billion. CEO Lip-Bu Tan called it “the strongest revenue growth in more than 15 years” and flagged the seventh consecutive quarter of exceeding financial expectations.

The bigger signal is capex. Zinsner guided 2026 capex above $20 billion, with 2027 significantly higher. That is a company building physical AI infrastructure with government support behind it, precisely the “critical asset” profile Son historically pays up for (the same power, cooling, and networking suppliers behind that buildout are the subject of a free report we put together here: 7 Stocks Powering the AI Boom). Intel’s Q3 2026 guide sits at $15.8B to $16.8B in revenue with 42% non-GAAP gross margin.

The Symbotic position ties in. Symbotic owns 35% of Exol, a SoftBank joint venture running warehouse-as-a-service under an approximately $11 billion contract, targeting a $500B+ annual TAM. T-Mobile is the legacy Sprint merger residue with a $18.2 billion 2026 stockholder return authorization.

What This Means for Retail Investors

The timing was not flattering. Between June 30 and August 14, 2026, Intel fell 26.59%, from $139.63 to $102.50. Son’s disclosed cost basis inside the quarter cannot be inferred from a 13F, but the position was underwater on a mark-to-market basis by the time the filing hit. Even so, Intel remains up 329.59% over one year. Analyst consensus target sits at $114.88, with a forward multiple near 81x. That valuation demands foundry execution, not just CPU tailwinds.

INTC price target

Son’s thesis is coherent, but the 67% concentration is a leveraged expression of it. Retirement-focused investors do not need to replicate the sizing to participate. Intel is investable on its own turnaround merits at a rational weight. Following Son’s conviction is defensible. Following Son’s position size is not.
