📈 Payment processors are middlemen with no pricing power
Chamath's read of Adyen dropping 40% in a day: Stripe, Adyen and PayPal are middlemen who must reflect their merchants' pricing power, so take rates and profit share compress structurally and margins can only be defended by cutting staff and levering opex. The surplus accrues to the buyers - Uber, McDonald's, DoorDash - not to the processors, making this a race to the bottom.

⚠ CONFLICTING IDEA ON THE SAME TICKER
— the board is arguing with itself; net it before trading (ticker view →)
⚖ Why this verdict
fully deterministic — evaluate.py replays this from daily closes; nothing below is editable or hand-set
- Window: 2023-08-18 → 2024-08-18 — first mention + 12-month horizon, then the window locks.
- The call: ▼ SHORT PYPL (primary play). PYPL rose 14.4% over the window → direction-adjusted R = -14.4% (the call lost money).
- Benchmark: holding SPY over the same window returned +28.8%
→ α = -14.4 − (+28.8) = -43.1%
— what this call made or lost against just owning the index. This is the number the verdict uses.
Stock-selection read: +14.4% — did PYPL move the predicted way relative to the market. The two only differ on a SHORT: this call was right about direction relative to the index but still cost money versus holding it.
- Rule fired:
· HIT — R ≥ +10% AND α ≥ +5· PARTIAL — R ≥ +5% OR α ≥ 0▶ MISS — everything else
- Credit: supporters of a MISS earn 0 each, opposers the inverse — this feeds the scoreboard weights. supported: Chamath, Sacks | opposed: Jason | proxy-sensitive: GPN→PARTIAL (+11.5%)

SUPPORT
“The thing to remember about all these businesses, Stripe, Adyen, PayPal, is that they're middlemen businesses, which by definition means that they don't have pricing power... So your margins over time tend to be compressed and over time your share of profits tend to be compressed and you have to give up a lot... So the real takeaway is that this is a very tough, tough business that is a race to the bottom.”
