📈 Builders green-light supply once the inflation boogeyman dies
Homebuilders have the capital but not the economic justification to build while they fear inflation, rate hikes and demand destruction. Once breakevens roll over, builders return in size, green-light projects and housing supply kicks back up aggressively — with a populist NIMBY-reform tailwind as young buyers get locked out by institutional bidders.

⚖ Why this result
fully deterministic — computed from daily closes on the scoring date; nothing below is editable or hand-set
- Window: 2021-06-13 → 2022-06-13 — first mention + 12-month horizon, then the window locks.
- The call: ▲ LONG ITB (primary play). ITB fell 20.1% over the window → return (sign flipped for a SHORT) = -20.1% (the call lost money).
- Benchmark: holding SPY over the same window returned -10.7% → vs SPY = -20.1 − (-10.7) = -9.4% — what this call made or lost against just owning the index. This is the number the result uses.
- Rule fired:
· RIGHT — return ≥ +10% AND beat SPY by 5+· HALF — return ≥ +5% OR beat SPY at all▶ WRONG — everything else
- Credit: supporters of a WRONG earn 0 each, opposers the opposite — this feeds the scoreboard. supported: Jason | opposed: Chamath, Sacks

OPPOSE
“restoration hardware sells overpriced crappy furniture into a housing market that's basically shut down because refi rates are at 5%. ... We have massive NIMBYism up and down the stack that prevents us from building the housing supply we need.”

SUPPORT
“I think what's happening now becomes the catalyst to break the NIMBYism. ... And, you know, you guys know I have a housing company in my portfolio. And they are getting absolutely deluge with people begging them to do affordable housing in different locations.”
