Five Things the Market Is Missing About SoFi

SoFi generated $4.8 billion in revenue in 2025, up from $2.1 billion in 2023. That's a 128% increase in two years. More telling: the growth rate accelerated from 30% in 2024 to 85% in 2025.

This isn't financial engineering. It's genuine product adoption. SoFi's member base has expanded from 5.2 million to over 9.4 million, with each new cohort using more products than the last. The average member now uses 2.8 SoFi products, up from 1.9 two years ago.

We've tracked fintech growth trajectories since the sector emerged, and very few companies sustain this kind of revenue acceleration past $2 billion in scale. SoFi has managed it by cross-selling lending, banking, investing, and insurance products through a single app — a strategy that's working because the unit economics improve with each additional product per member.

SoFi swung from negative $300 million in operating income to positive $1.7 billion in just two years. The operating margin went from negative 14% to positive 18.2%.

This wasn't achieved through cost-cutting. Revenue grew so fast that fixed costs — technology infrastructure, regulatory compliance, brand marketing — were leveraged over a much larger revenue base. The incremental margin on each new dollar of revenue exceeds 40%, which means profitability compounds faster than revenue from here.

At 28x forward earnings, SoFi is cheaper than Block (28x) despite growing twice as fast. The 8 holds and 2 sells on the street suggest analysts are anchored to the old loss-making SoFi. The data has moved past them.

SoFi received its national bank charter in 2022. Three years later, the impact is visible in every financial metric.

As a chartered bank, SoFi can hold deposits (now exceeding $24 billion) and lend against them directly, rather than funding loans through warehouse facilities and securitisations. The cost of capital dropped from 5-6% to 2-3%, instantly expanding net interest margins by 200-300 basis points.

The deposit base is growing at 35% annually and is predominantly direct deposit — the stickiest form of consumer banking relationship. Once a member's salary hits their SoFi account, the switching costs become enormous. This is the fintech moat that traditional banks fear.

SoFi's technology platform segment — built on the Galileo payments infrastructure and Technisys core banking software acquired in 2022 — processes over 160 million accounts for third-party clients. These are other fintechs and banks that use SoFi's infrastructure to power their own products.

The platform segment is growing at 40% annually with 55% gross margins. It's a genuine SaaS-like business embedded inside what the market treats as a consumer lending company.

If you value the tech platform at 8x revenue — conservative for a 40%-growth, 55%-margin software business — it's worth approximately $6-8 billion. That means the market is valuing SoFi's consumer banking franchise at just $13-15 billion. For a bank with $24 billion in deposits growing at 35%, that's absurdly cheap.

SoFi was founded as a student loan refinancing company. The pandemic-era moratorium on federal student loan payments crushed this business for three years. Payments resumed in late 2023, and refinancing volumes have been recovering since.

Student loan refinancing was historically SoFi's highest-margin lending product, with net interest margins exceeding 4%. As the $1.6 trillion student loan market normalises and borrowers seek lower rates, this segment could add $500 million-$1 billion in annual revenue by 2027.

The market treated the moratorium as a permanent impairment. It wasn't. And the recovery in this segment represents pure upside that's barely reflected in current estimates.
