SoFi Technologies, Inc. SOFI and Nu Holdings Ltd. NU are often grouped as digital banking disruptors, and the comparison makes sense. Both use mobile-first platforms to attract customers, deepen relationships through cross-selling, gather deposits, extend credit and add investing or other financial tools. Both are also using artificial intelligence to improve engagement and decision-making, while scale is increasingly turning their technology-led models into durable earnings engines.
The difference is where the growth comes from. Nu already operates at enormous scale across Brazil, Mexico and Colombia, so its next phase depends increasingly on monetizing existing customers, expanding credit carefully and entering new markets.
SoFi is smaller, but its U.S.-focused ecosystem is becoming broader, with lending, banking, investing, technology services and digital-asset infrastructure working together. This gives SoFi more visible room to raise products per member and diversify revenues. Both have execution risks, but their growth paths are becoming increasingly distinct rather than interchangeable. This contrast matters for investors.
The Case for SOFI
SoFi’s strongest advantage is that its ecosystem is starting to work more like a connected financial platform than a collection of separate products. Members reached 15.8 million in second-quarter 2026, up 35% year over year, while products grew 42% to 24.4 million. Moreover, 51% of new products came from existing members. The cross-buy trend supports higher lifetime value without requiring the same acquisition spending for every new service.
SoFi Plus strengthens that argument. The paid membership passed 200,000 subscribers, and many members added another product afterward. SoFi can increasingly turn checking, investing, credit and lending into one relationship. Compared with Nu, whose scale is already massive, SoFi has more room to deepen a much smaller member base.
The revenue mix is also improving. Fee-based revenues represented 39% of second-quarter adjusted net revenues, while the loan platform business, interchange, brokerage and technology services expanded the ways SoFi can earn without relying solely on balance sheet lending. This diversification could make growth more durable and capital efficient over time.
Recent product expansion adds another layer. SoFi expanded private-market access through funds from CAZ Investments and AngelList, while its Payward partnership connects Big Business Banking, the SoFi Exchange Network and SoFiUSD with Kraken. These initiatives could strengthen investing, payments and enterprise relationships if adoption develops as planned.
Execution still matters, especially in credit and technology services. Yet the combination of accelerating cross-buy, stronger fee generation, new enterprise capabilities and a broad U.S. product set gives SoFi the more compelling growth setup versus Nu.
