Bullish Case: Custom AI ASIC ramp, Google revenue contribution scaling into FY2029, and the Polariton plasmonics acquisition give MRVL durable interconnect differentiation. Calls traded 48% above puts, bullish risk exceeds bearish by 6%, and term structure is in contango (~56% Oct vs ~67% Jun-2027) — pricing calm. The Helium density mode sits right at $260-262.5 vs spot $251.9; a reclaim of $262.36 (week-ago level) opens $280+ into Nov expiries.

Bearish Case: AI forecast is -1.45% with -0.2 correlation to realized moves, 90-day tape is -7.4%, and the Aug 28 post-Q2 drop shows guidance fatigue. Option volume sits at the 9th percentile — thin flow means crowded 10/02 260-270 calls can unwind fast. SPY surface shows a hot downside wing (~35 vol at $439 tail), so any macro de-rate hits high-beta MRVL toward the $220-230 density shoulder.

Potential Outcomes:

1. 32% — Range $245-265 through Oct: contango holds; falsified by IV spike or break of $245.
2. 26% — Upside $270-285 by Nov 21: call dominance 48%; falsified by call/put flip.
3. 22% — Pullback $225-245: Helium -1.45% + thin volume; falsified by holding >$255 on dips.
4. 12% — Vol event ±12%: earnings/news; falsified by flat IV.
5. 8% — Break <$220: SPY de-rate; falsified by put skew cooling.
