U.S. investors can buy SoftBank Group Corp. stock through over-the-counter (OTC) markets using the ticker symbols SFTBY or SFTBF, both available at most major online brokerages. SoftBank’s primary listing trades on the Tokyo Stock Exchange under ticker 9984, but you don’t need direct access to a Japanese exchange to invest. Here’s how each option works and what to expect.
Three Ways to Buy SoftBank Stock
SoftBank Group trades under three symbols, and the one you choose depends on your brokerage and how much complexity you’re comfortable with.
- SFTBY (ADR, OTC) — This is the most accessible option for U.S. investors. SFTBY is an American Depositary Receipt, which means a U.S. bank holds the underlying Japanese shares and issues dollar-denominated receipts that trade on the OTC market. You buy and sell in U.S. dollars during regular U.S. market hours. Most major brokerages support this ticker.
- SFTBF (Ordinary Shares, OTC) — This represents the actual ordinary shares of SoftBank Group trading on the U.S. OTC market. It’s less liquid than SFTBY, meaning fewer shares change hands each day, which can result in wider bid-ask spreads and slightly less predictable pricing.
- 9984.T (Tokyo Stock Exchange) — SoftBank’s primary listing in Tokyo, priced in Japanese yen. Few U.S. retail brokerages offer direct access to the Tokyo Stock Exchange. Interactive Brokers is one of the notable exceptions. Buying here requires a currency conversion to yen, and you’ll trade during Tokyo hours: 9:00 a.m. to 11:30 a.m. and 12:30 p.m. to 3:30 p.m. Japan Standard Time, which translates to roughly 7:00 p.m. to 2:30 a.m. Eastern Time depending on the season.
For most U.S. investors, SFTBY is the simplest path. It trades like any other stock in your brokerage account, settles in dollars, and doesn’t require navigating foreign exchange or overnight trading sessions.
How to Place the Trade
If you already have a brokerage account, buying SFTBY takes the same steps as buying any U.S.-listed stock. Search for the ticker, enter the number of shares, choose a market or limit order, and submit. A limit order is worth considering here because OTC stocks can have wider spreads between the highest price a buyer is offering and the lowest price a seller will accept. Setting a limit lets you control the maximum price you’ll pay.
If you don’t have a brokerage account yet, you can open one online at firms like Fidelity, Charles Schwab, or Interactive Brokers, typically in under 15 minutes. You’ll need a Social Security number, a government-issued ID, and a linked bank account for funding. Most accounts can be funded and ready to trade within one to three business days.
Some brokerages charge a small fee for OTC trades on top of their standard commission, so check your platform’s fee schedule before placing the order. A few brokerages also charge a foreign settlement fee on ADR transactions.
What You’re Actually Buying
SoftBank Group is not a single-product company. It’s a holding company with a sprawling portfolio of technology investments, and owning its stock means you’re getting indirect exposure to all of them.
The most prominent asset is Arm Holdings, the semiconductor design company whose chip architecture powers most of the world’s smartphones. SoftBank holds a controlling stake in Arm, which is publicly traded on its own under the ticker ARM on the Nasdaq. This single holding represents a significant portion of SoftBank’s total value.
Beyond Arm, SoftBank operates the Vision Fund, a massive investment vehicle focused on technology companies across sectors like AI, fintech, and logistics. The Vision Fund’s performance can swing SoftBank’s reported earnings dramatically from quarter to quarter. SoftBank also owns SoftBank Corp. (a separate publicly traded Japanese telecom company), a stake in LY Corporation (which operates Yahoo Japan and the LINE messaging platform), the fashion e-commerce site ZOZO, the mobile payment service PayPay, and dozens of other companies.
The company has been expanding into AI computing infrastructure, with investments in chipmakers and computing platforms like Graphcore and Ampere Computing. When you buy SoftBank Group stock, you’re essentially buying a bet on the future of technology through the investment decisions of its founder, Masayoshi Son.
Taxes and Fees on Dividends
If SoftBank pays a dividend, Japan withholds tax before it reaches you. Under the U.S.-Japan tax treaty, the withholding rate for U.S. residents is 10%, potentially plus a small income surtax of 2.1%. So if SoftBank declares a dividend, you’ll receive about 90% of it in your account.
The good news is that you can typically claim a foreign tax credit on your U.S. tax return for the amount Japan withheld, which prevents you from being taxed twice on the same income. If you hold the shares in a taxable brokerage account, you’ll report this on IRS Form 1116. In a retirement account like an IRA, you generally can’t claim the credit, so the foreign withholding becomes a permanent cost.
ADR holders may also be charged a periodic custody fee by the depositary bank that manages the underlying shares. These fees are usually small, often a few cents per share per year, and are typically deducted from dividend payments.
Liquidity and Pricing Considerations
SoftBank’s primary market is Tokyo, where the vast majority of trading volume occurs. The OTC-traded SFTBY and SFTBF tickers see much lower volume. On quiet trading days, this can lead to wider spreads and prices that lag slightly behind the Tokyo market.
Because the Tokyo Stock Exchange operates overnight in U.S. time zones, significant news can break while U.S. markets are closed. The OTC price will adjust when U.S. trading opens, sometimes with a gap up or down. If you place a market order before checking the overnight Tokyo session, you could end up buying at a price that reflects news you haven’t seen yet. Checking the 9984.T closing price from Tokyo before placing your U.S. order is a practical habit.
Currency Risk
Even when you buy SFTBY in U.S. dollars, you’re exposed to fluctuations in the Japanese yen. SoftBank’s underlying assets and earnings are denominated in yen (and various other currencies for its global investments). If the yen weakens against the dollar, the value of your ADR shares can decline even if SoftBank’s stock price in Tokyo stays flat. The reverse is also true: a strengthening yen can boost your returns. This currency effect is built into the ADR price automatically, so there’s nothing extra you need to do, but it’s a real factor in your total return.
