📈 US housing is millions of units short and demand is off the charts

Jason's framing of the other side of the real-estate story: while office sits in massive oversupply with no demand, single-family housing is roughly 7 million units short with demand off the charts, which is an incredible market for developers. Sacks pushes back that residential is not a good market either because financing costs, not vacancy, are the binding constraint.

⚖ Why this verdict

fully deterministic — evaluate.py replays this from daily closes; nothing below is editable or hand-set

  1. Window: 2024-02-09 → 2025-02-09 — first mention + 12-month horizon, then the window locks.
  2. The call: ▲ LONG ITB (primary play). ITB fell 0.0% over the window → direction-adjusted R = -0.0% (the call lost money).
  3. Benchmark: holding SPY over the same window returned +21.4%α = -0.0 − (+21.4) = -21.4% — what this call made or lost against just owning the index. This is the number the verdict uses.
  4. Rule fired:
    · HIT — R ≥ +10% AND α ≥ +5
    · PARTIAL — R ≥ +5% OR α ≥ 0
    ▶ MISS — everything else
  5. Credit: supporters of a MISS earn 0 each, opposers the inverse — this feeds the scoreboard weights. supported: Chamath, Friedberg, Jason | opposed: Sacks | proxy-sensitive: XHB→PARTIAL (+6.7%)

“Paradoxically, on the other side, we have this incredible market for developers, which is, gosh, there's not enough homes. I think we need 7 million more homes, and the demand is off the charts for homes, yeah?”

“I keep trying to explain residential is not a great market either because interest rates have spiked up. So there's not a vacancy problem. Multifamily developers are still able to lease the units. They're still able to rent. The problem is their financing costs have shot through the roof.”
Friedberg
Friedberg equities w=0.87 · n=120 · E211 (2025-01-18) · sentiment · strength 1 ▶ 28:44 SUPPORT
“There is a home building dearth right now in the United States. So this is an amazing opportunity because they can now move to LA, build homes.”
