SoftBank's Portfolio Presents a Tale of Two Strategies

SoftBank's PayPay IPO fuels growth hopes, but its flagship U.S. AI data center faces major legal and regulatory threats, creating a pivotal moment for investors.

As SoftBank Group prepares to report its annual results in May, investors are weighing two powerful but opposing forces within its portfolio. On one side, the recent IPO of its digital payments champion, PayPay, is generating significant analyst optimism. On the other, a flagship U.S. artificial intelligence project faces mounting legal and regulatory threats that could undermine a cornerstone of the conglomerate's infrastructure strategy.

The positive momentum stems from PayPay's debut on the Nasdaq in March 2026, the largest U.S. listing for a Japanese company in ten years. With the post-IPO quiet period over, Wall Street banks have initiated coverage with bullish outlooks. Jefferies issued a buy rating with a $28 price target, while Bank of America and Wolfe Research each set targets of $26. Analysts highlight PayPay's dominant position in Japan's QR-code payment market, where it controls approximately 64% of transactions and serves about 72 million registered users—roughly 60% of the country's population. With Japan's cashless payment ratio still at just 42.8%, far below South Korea's 99%, the government's target of 65-80% provides a clear growth runway. Furthermore, only around 14% of PayPay's payment users currently hold an account with its affiliated PayPay Bank, pointing to substantial untapped cross-selling potential.

However, this optimism is tempered by serious challenges facing SB Energy's ambitious "Piketon AI Data Center Complex" in Ohio. A local citizen initiative is gathering signatures for a state constitutional amendment that would impose a strict construction ban on data centers with a peak load exceeding 25 megawatts. They need roughly 413,000 valid signatures by July 1. This poses a direct threat to SoftBank's plans, as the envisioned Ohio complex is slated to reach a colossal 10 gigawatts at full build-out—more than half of the United States' entire current data center capacity concentrated at a single site.

Simultaneously, a dispute over electricity tariffs is before the Ohio Supreme Court. A new rate aims to prevent residential customers from subsidizing grid costs for large data centers, requiring major consumers to pay for at least 85% of their committed capacity for twelve years. Industry groups are challenging this rule as discriminatory.

The project's very foundation was shaken by a February 2026 U.S. Supreme Court ruling that struck down a tariff program the U.S. government used as leverage in trade negotiations. This specific program formed the diplomatic framework for Japan's $550 billion investment pledge in the U.S., which included the Ohio initiative. The first construction phase alone carries an estimated price tag of $30 to $40 billion. Without the tariff pressure, the incentive for SoftBank to uphold its commitments may diminish as financial risks rise.

This strategic uncertainty is already influencing institutional investors. The Hennessy Japan Fund significantly reduced its position in SoftBank Group in the first quarter of 2026, selling 470,800 shares—a 41% cut—at an average price of 4,548.57 yen. SoftBank's share price has reflected the pressure, declining about 16% since the start of the year.

All eyes now turn to the upcoming earnings presentations. SoftBank Corp. will report on May 11, followed by SoftBank Group on May 13. Management will need to detail how the Ohio hurdles impact financial planning, especially after shifting 60% of its assets into AI investments. Additionally, the financing structure for its $40 billion stake in OpenAI will be scrutinized. Each tranche is funded separately via unsecured bridge loans with twelve-month maturities, a structure market observers interpret as banks anticipating an OpenAI IPO before year-end. How investors assess this balance sheet burden will be a key test.

While PayPay offers a bright spot of growth and validation, the fate of the Ohio mega-project underscores the complex geopolitical and execution risks embedded in SoftBank's aggressive pivot to AI infrastructure. The May results will reveal how the group navigates this stark divergence within its own portfolio.
