📈 AI adoption disperses the S&P — short the index, own the category killers
The Mag 7 have decoupled for the first time in years (Meta +18, Microsoft +13, Nvidia +8, Amazon -3, Google -8, Tesla -20, Apple -21 YTD) and the same sorting now runs through the S&P 493, whose average member grows single digits on a 12% margin. Firms that rebuild their operations with AI take the share and margin of the ones that don't, so the index itself is the wrong thing to own: the trade is to short the broad market and hold a handful of category killers. Thomas Laffont frames it as the best stock-picker's market in decades, Chamath will not be long the 493, and Friedberg says it is the first time in twenty years he would short the S&P and pick winners.

⚖ Why this verdict
fully deterministic — evaluate.py replays this from daily closes; nothing below is editable or hand-set
- Window: 2025-06-21 → 2026-06-21 — first mention + 12-month horizon, then the window locks.
- The call: ▼ SHORT RSP (primary play). RSP rose 19.1% over the window → direction-adjusted R = -19.1% (the call lost money).
- Benchmark: holding SPY over the same window returned +25.8%
→ α = -19.1 − (+25.8) = -44.9%
— what this call made or lost against just owning the index. This is the number the verdict uses.
Stock-selection read: +6.7% — did RSP 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, Friedberg, Thomas Laffont

“I'm wondering if this is the year where we've seen the greatest divergence amongst the Mac 7, right? ... now the market is saying, wait, hold on, we might start to see diverging performance.”

“why would you belong any of these 493 companies that may turn around and one day just get decapitated by something you don't even know that's getting cooked up by a couple of kids in a garage using open AI or GROC or what have you?”

SUPPORT
“I think it's the first time you could probably argue that you could go short the S&P and pick a couple of winners. ... I do think that this is such a transformative moment that if you really have a sense for what's possible, you could start to see category killers emerge out of the S&P, and it's an opportunity to short the S&P and pick a couple of winners.”
