SoftBank's PayPay Acquires 40% Stake in Binance Japan, Eyes U.S. Stock Market Debut
October 9, 2025
In a strategic move to capitalize on Japan's rapidly growing crypto market, SoftBank's mobile payment subsidiary PayPay has acquired a 40% stake in Binance Japan, aiming to integrate cashless payments with digital assets.
This partnership will enable users to purchase cryptocurrencies directly using their PayPay balance and withdraw proceeds to PayPay accounts, making crypto transactions more accessible.
The alliance seeks to leverage PayPay's extensive user base and infrastructure alongside Binance's blockchain technology to enhance financial services in Japan.
SoftBank has historically been cautious about crypto but is now positioning PayPay for a potential U.S. stock market debut valued at over $10 billion, signaling a significant shift in its strategy.
PayPay has expanded internationally, launching in South Korea and confidentially filing for a US stock exchange listing of American depositary shares, with plans to further grow its global presence.
The investment, made for an undisclosed sum, reflects SoftBank's broader interest in expanding its footprint in the crypto industry, which includes exploring investments in stablecoins like Tether.
Binance's entry into Japan, a highly regulated market, offers a strategic opportunity to bolster its global legitimacy following regulatory challenges elsewhere, with Binance Japan operating since August 2023.
The recent rally in Binance's native token BNB, which hit around $1,300 and a market cap of approximately $182 billion, underscores increased market interest and the potential impact of this partnership.
The success of this collaboration depends heavily on operational execution and regulatory approval, which will influence PayPay's market positioning and its IPO timeline amid volatile market conditions.
Japan's evolving regulatory landscape, including plans to recognize crypto assets as financial products and issue yen-pegged stablecoins, has facilitated such collaborations and positioned the country as a forward-looking crypto hub in Asia.
This partnership extends PayPay's ecosystem into Web3 finance, with future services expected to include direct crypto trading, innovative financial products, and educational initiatives to promote digital assets.
The alliance aims to lower barriers to crypto adoption among Japanese consumers, fostering familiarity and confidence in digital assets, while also supporting PayPay's broader goal of expanding beyond Japan into regions like South Korea, Taiwan, and the US.
