SoFi wins the long-term fintech battle not because it avoids cycles, but because it survives them with profitability intact

SoFi Technologies reported 38% adjusted revenue growth in 2025 and forecasts 30% growth in 2026. That momentum isn’t just top-line expansion — it’s flowing straight to the bottom line. SoFi achieved its first full year of GAAP profitability in 2024. Adjusted net income jumped 112% last year and is projected to soar 72% in 2026. Its customer base now stands at 13.7 million, up 161% in three years. This isn’t speculative traction. It’s scaling with discipline.

Upstart, by contrast, performs only when conditions tilt in its favor. Its AI-driven lending platform, which analyzes over 2,500 variables and bypasses FICO scores, thrived in 2020 and 2021 when rates fell. But when rates rose in 2022 and 2023, loan volumes dropped, revenue shrank, and the company posted substantial net losses. Cyclicality isn’t a bug in Upstart’s model — it’s baked into the architecture. The company projects 40% revenue growth in 2026, but that forecast hinges on rate stability, a condition the past five years have not provided.

Muddy Waters issued a short report in March alleging SoFi inflates profits and understates loan losses. SoFi disputes the claims and is pursuing legal action. CEO Anthony Noto bought $500,000 in shares post-report. As a federally chartered bank, SoFi operates under stringent regulatory oversight — a structural check Upstart lacks. Even if scrutiny intensifies, SoFi’s path to profitability is already proven. Upstart, meanwhile, is applying for a national bank charter, seeking lower-cost capital through deposits. But that move would pull it toward the very traditional lending model it was built to disrupt — and further expose it to rate cycles.

The better long-term fintech play isn’t the one that wins in ideal conditions. It’s the one that keeps gaining ground when conditions turn. SoFi’s growth is broad, its profits real, and its valuation — trading 50% below its peak at a 27.8 forward P/E — reflects tempered expectations. Upstart may ride AI hype and sell-side optimism of 31% annual EPS growth through 2028, but performance in falling rates proves only half the story. The full story requires surviving the rise. The fintech stock with consistent financial gains and regulatory stability is better positioned for long-term investor returns.
