Shares of SoftBank Group surged 10.6% to ¥6,370 on July 10, snapping a week-long slide, after Bloomberg reported that its telecom subsidiary and payments arm are negotiating a major equity stake in Seven & i Holdings — the parent of 7-Eleven. The Nikkei reported total investment is expected to reach up to ¥300 billion ($1.85 billion) , with Seven & i potentially issuing new shares to be acquired by SoftBank and PayPay . Sumitomo Mitsui Financial Group's credit card unit is also said to be weighing participation, with parties aiming to reach an agreement this summer.
¥300 Billion Is Big, but SoftBank's Balance Sheet Is Bigger For context, SoftBank Group's market cap stands at ¥36.3 trillion , and its cumulative investment in OpenAI alone is projected to exceed $60 billion by year-end, with $64.6 billion committed through Vision Fund 2 . A ¥300 billion retail bet is modest by comparison — roughly 0.8% of SoftBank's market value — yet the stock's violent reaction suggests investors see something more strategic than the dollar figure alone.
The Real Prize: 74 Million Payment Users Meet 20,000 Stores
PayPay boasts approximately 74 million registered users as of early July 2026 — Japan's dominant mobile payments platform. Combining Seven & i's store network with payment data would enable more targeted loyalty programs and promotions . If talks materialize, Seven & i gains powerful partners in telecom and payments, creating a direct counter to the Lawson-KDDI digital alliance — a rivalry that is rapidly reshaping how Japan's 56,000-plus convenience stores compete.
AI in the Aisles Is the Wild Card
SoftBank aims to deploy its in-house AI to improve store management and introduce autonomous robots to reduce labor costs at Seven & i locations . If rolled out across roughly 20,000 domestic stores, it would represent the largest-scale AI deployment in retail. That is the ambitious pitch — but execution risk is high, and no timeline has been disclosed.
The Stock Remains Well Below Its Peak — for Good Reason Even after the pop, SoftBank trades within a 52-week range of ¥2,551 to ¥9,074 , sitting 30% below its June 2 high. The consensus analyst rating is "Buy," with a 12-month target of ¥6,829 — just 7% above today's price. Discussions remain fluid, with no guarantee a deal closes. Investors are effectively betting that Masayoshi Son can stitch together AI, payments, and convenience stores into a cohesive profit engine — a thesis that looks exciting on paper but has yet to ring a single register.
