SoFi Technologies vs. Upstart: Which Fintech Stock Is the Better Long-Term Buy?

The article argues SoFi is the better long-term fintech play, citing 38% adjusted revenue growth in 2025, a forecast 30% increase in 2026, and projected 72% growth in adjusted net income in 2026. It also notes SoFi’s first full year of GAAP profitability in 2024, 13.7 million members, and a forward P/E of 27.8 after shares fell 38% in 2026 and trade 50% below their record, while Upstart remains highly cyclical despite expected 40% revenue growth in 2026. The main overhang for SoFi is Muddy Waters’ short report and related litigation, but the piece characterizes the allegations as not yet a reason to panic.

Analysis

The market is treating this as a binary quality-vs-cyclicality debate, but the real divergence is balance-sheet optionality. SOFI’s business model should be more resilient to a slower macro backdrop because it monetizes a broader customer relationship and can cross-sell into deposit-funded products; that creates a compounding flywheel if credit stays orderly. UPST, by contrast, is still a throughput machine: when funding is cheap and credit is benign, operating leverage works hard, but its earnings power can shrink abruptly when rate volatility or spread widening disrupts partner appetite.

The short-report overhang on SOFI is a near-term sentiment risk, but it also creates a cleaner setup if management can continue showing benign charge-offs and deposit growth. The key second-order effect is that any loss of confidence in reported economics would not just compress the multiple; it would raise deposit funding costs and slow member acquisition, turning an accounting dispute into a real business issue. That makes the next 1-2 quarters more about proof than narrative, especially around credit trends and funding mix.

UPST has more upside torque if rates keep falling, but that is not a durable edge. The market is likely underestimating how much of UPST’s model is effectively long duration credit spread exposure disguised as AI underwriting; if unemployment ticks up while rates fall, the signal could be mixed rather than bullish. The better contrarian view is that SOFI’s multiple is already discounting litigation risk and some skepticism, while UPST still prices in a cleaner cyclical rebound than the macro may deliver.

Key Decisions for Investors

• Long SOFI vs short UPST as a 3-6 month pair trade: prefer the name with recurring funding advantages and broader monetization; target 15-25% relative outperformance if credit remains stable and rates stay rangebound.
• Buy SOFI on weakness only after management updates next quarter: use the short-report event as a timing filter, not a thesis breaker; risk/reward improves if the stock stays >15% below recent highs while fundamentals hold.
• Avoid chasing UPST on any rate-cut rally; use strength to fade via call overwrites or short-dated put spreads, since the business still screens as high beta to funding conditions and loan volume elasticity.
• If you want convexity on a downside macro surprise, express it through UPST puts rather than SOFI shorts: UPST should re-rate faster if credit spreads widen or unemployment rises over the next 1-2 quarters.
