📈 Rate-arbitrage fintechs implode as their cost of capital rises
Neobanks and consumer-lending fintechs funded at exorbitant valuations are fundamentally an arbitrage on zero rates — take money at 0%, sell it at 1%, keep the spread. At a 2-3% cost of capital the model implodes, so the whole funded neobank/lending cohort comes under pressure.

⚖ Why this verdict
fully deterministic — evaluate.py replays this from daily closes; nothing below is editable or hand-set
- Window: 2022-03-26 → 2023-03-26 — first mention + 12-month horizon, then the window locks.
- The call: ▼ SHORT SOFI (primary play). SOFI fell 38.0% over the window → direction-adjusted R = +38.0% (the call made money).
- Benchmark: holding SPY over the same window returned -11.7%
→ α = +38.0 − (-11.7) = +49.7%
— what this call made or lost against just owning the index. This is the number the verdict uses.
Stock-selection read: +26.2% — did SOFI move the predicted way relative to the market. The two only differ on a SHORT: this call beat the index outright.
- Rule fired:
▶ HIT — R ≥ +10% AND α ≥ +5 ✓ (R 38.0, α 49.7)· PARTIAL — R ≥ +5% OR α ≥ 0· MISS — everything else
- Credit: supporters of a HIT earn 1.0 each, opposers the inverse — this feeds the scoreboard weights. supported: Chamath

SUPPORT
“Neobanks are another example. The number of Neobanks that have been funded at exorbitant valuations, where the problem is all of these financial services companies are essentially an arbitrage on rates. When rates are zero, they take that money at 0% and then they can go and execute a business model and sell that money at 1% and take the difference. But when their cost of capital is 2 or 2.5 or 3%, the whole business implodes on them. So you're going to see a bunch of these financial services companies get under pressure.”
