Multiple credible, high-authority news reports based on regulatory SEC filings confirm that SoftBank sold its Nvidia stake during the fourth quarter as part of a portfolio adjustment. Reuters directly states that SoftBank dissolved its Nvidia stake in Q4, with contextual framing that this was part of broader strategic asset realignment. MSN, Finbold, and MarketBeat reports echo this point, noting the sale volume amounted to over $5 billion worth of shares and aligning it with institutional rebalancing. Although exact share counts are not always specified in every outlet, some coverage implies that the quantity sold was consistent with more than 32 million shares based on valuation and price at the time, supporting numerical plausibility. There are no credible reports contradicting this claim, and all evidence points to the sale occurring in Q4, linked to portfolio changes, making the statement highly probable.
