Bullish Case: Known: ADPT ~22.58 and flat; ADPT IV surface shows a hotter put wing but comparatively cooler around the $20–25 strike region, consistent with priced uncertainty rather than collapse. Helium’s AI forecast is +4.08% and ADPT return-surface likelihood clusters in modest positives (+0–+30%) for near-term holding. Calibrated vs Mar/May: limited big upside so far, favoring a warm-band re-rate after Jul 29.

Bearish Case: Known: ADPT options sit in backwardation and the implied-vol surface shows a much higher left tail (puts) than right tail (calls), with insider selling after an 85% run. Inferred: hedging/risk-off demand around event dates. Uncertain: whether Jul 29 guidance or Medicare/MRD momentum disappoints. ADPT return-surface still allocates non-trivial probability to large negatives (to ~-70%). If SPY vol wings rise, ADPT’s beta (~2.07) can magnify drawdowns. Calibrated: -20% to -35% hasn’t hit recently, but is still priced.

Potential Outcomes:

1. 45%: Post–Jul 29 beat on revenue/MRD; ADPT 25C/30C IV falls vs 25P; +5–20% move.
2. 30%: Earnings confirm only; backwardation persists; SPY wings stay bid; -5–+7% chop.
3. 20%: Guidance/Medicare or MRD miss; put-skew steepens; -20–-35% drawdown.
4. 5%: Deal/upgrade surprise; volatility compresses; +40–+80%.

Oracle (conditional): if 25P IV jumps into earnings, odds tilt bearish; if skew eases, defined-risk upside becomes more credible.
