🏛️ Medicare price negotiation compresses pharma pricing power and biotech returns
The IRA's prescription-drug price cap and Medicare negotiation authority — the second-largest line in the bill — permanently lowers the price the largest buyer in the market pays, cutting pharma revenue, the R&D it funds, and the returns available to biotech investors. Sacks calls it price fixing with a downstream hit to new-drug funding; Friedberg thinks the drug-count effect is small but concedes biotech IRRs fall from ~48% to ~28%.

⚖ Why this result
fully deterministic — computed from daily closes on the scoring date; nothing below is editable or hand-set
- Window: 2022-08-20 → 2023-08-20 — first mention + 12-month horizon, then the window locks.
- The call: ▼ SHORT XBI (primary play). XBI fell 9.8% over the window → return (sign flipped for a SHORT) = +9.8% (the call made money).
- Benchmark: holding SPY over the same window returned +7.3%
→ vs SPY = +9.8 − (+7.3) = +2.5%
— what this call made or lost against just owning the index. This is the number the result uses.
Direction-only read: +17.1% — did XBI 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:
· RIGHT — return ≥ +10% AND beat SPY by 5+▶ HALF — return ≥ +5% OR beat SPY at all· WRONG — everything else
- Credit: supporters of a HALF earn 0.5 each, opposers the opposite — this feeds the scoreboard. supported: Chamath, Friedberg, Sacks | proxy-sensitive: IBB→MISS (-0.1%); PFE→HIT (+22.0%)

“And, you know, they're in the midst right now of completing a massive facility. I think it's in Virginia where they'll be able to make as much insulin as is needed for the entirety of America for no more than 35 bucks a dose.”

SUPPORT
“Well, I mean, you're saying that these drug companies are going to make a lot less money. Well, obviously, that's going to have a downstream impact in the willingness to fund new drugs, new investment, new R&D.”

SUPPORT
“And so I'm hopeful that this will actually provide a more effective market force in allowing the biggest customer in the market to negotiate prices and that the VCs, instead of making 48% IRR, they'll ultimately make 28% IRR on the investments that they're making in biotech startups.”
