AI Analysis · Q1 2026

SoftBank Group's U.S.-listed 13F portfolio contracted by more than $4 billion in the first quarter, falling from $15.5 billion to $11.4 billion — a 26% decline that stands out even against a volatile quarter. The dramatic reduction was not the result of broad market losses alone. The portfolio actively shed a giant T-Mobile position, unloading close to two-thirds of the stake in a single quarter and pulling roughly $3.7 billion from a single line item. That single trade more than accounts for the quarter-to-quarter AUM decline, which means the rest of the book largely held its value against a period when the Nasdaq was under pressure. The remaining portfolio is highly concentrated in just a few large AI and telecommunications-oriented positions. Intel became the anchor at 33.6% of the book, or $3.84 billion — a holding size that makes this portfolio structurally sensitive to semiconductor-cycle swings. Symbotic, SoftBank's warehouse-automation AI bet, sits in second place at $2.12 billion, followed by a slimmed-down T-Mobile exposure of $2.10 billion. Taiwan Semiconductor Manufacturing rounds out the top four at $671 million, slightly increased from the prior quarter and pointing toward continued conviction in the semiconductor supply chain despite Intel's outsized weighting. What the portfolio is not — or no longer is — is a T-Mobile-heavy communication-services vehicle. That prior-quarter identity was true: TMUS represented $5.79 billion, or 37% of assets. That concentration is now gone. The quarter also saw four positions liquidated, including Lemonade, Circle Internet Group, a small Uber stake, and a token Coinbase position — a sweeping cleanup late-stage fintech and crypto-screening round. But there were no new entries of any meaningful size; the trust appears to have converted the freed capital into cash rather than rotated it into new themes. This is a portfolio in deliberate contraction, rebalancing away from a telecommunications-heavy prior structure toward a tighter, more semiconductor-concentrated, and less diverse book.

The quarter's defining transaction is the T-Mobile US reduction. At year-end 2025, TMUS accounted for $5.79 billion, or 37.4% of the entire portfolio — a weighting that already represented outsized single-name risk tied to a single U.S. wireless carrier. By March 31, that position had been cut by nearly 65%: shares outstanding dropped from 28.5 million to 10 million, value fell to $2.10 billion, and the position's share of book compressed from 37.4% to 18.4%. In dollar terms, SoftBank pulled $3.69 billion from TMUS alone in a single quarter, making it the dominant driver of the portfolio's overall AUM contraction. This is not a trimming motivated by a negative thesis on T-Mobile specifically — the position was not fully exited, just normalized — and it may reflect the trust's broader discipline of managing single-name concentration risk in positions that had grown too large.

That freed capital, however, was not recycled into new holdings. The changes summary records zero increased positions and only a single new entry: Ethos Technologies at $35 million, a nearly negligible addition. Combined with four positions that were liquidated entirely — Lemonade (worth $65.9 million at exit), Circle Internet Group, a token UBER position of $1.5 million, and an even smaller Coinbase remnant — the quarter's net trading activity points to a portfolio that raised cash rather than rotated it. This is worth noting because it suggests the portfolio manager was not chasing new AI or fintech themes into the weakness but rather paused deployment, presumably to wait for clearer entry points after a volatile Q1.
