Bullish Case: Flat SABR term structure with very high, strike-invariant IV on the vol-surface, and a return-surface likelihood cluster around small positive % gains. Helium’s IV sits above market’s (mild underpricing of risk), but the uncertainty-diff isn’t wildly negative—compatible with mean reversion. Since late April/May, price is +6–7% from ~$1.76 to $1.88, aligning more with my earlier “small-gain” base-case than bearish tails. Bias: ~$1.94–$2.00 into Jun 18 / Jul 17 expiries.

Bearish Case: Downside tail remains priced: far-dated puts show extreme IV (01/21/2028 0.50P ~500%), and the return surface has nontrivial negative-return likelihood. SPY’s vol surface is steadier (teens–20s), so SABR-specific shocks could dominate. Helium–market uncertainty is slightly positive, implying market may under-price stress. If SABR loses ~$1.80–$1.85 into Jun 18 and lower-strike put IV re-bids (surface brightens), a -5% to -10% drift toward ~$1.70–$1.78 is plausible.

Potential Outcomes:

1. 45%: +0–4% by Jul17 if SABR stays >1.85 and 6/18 call IV doesn’t expand.
2. 25%: -2–+2% if SPY IV remains ~teens/20s and SABR mean-reverts.
3. 20%: +5–15% if SPY IV upticks and SABR call skew steepens (realized vol beats term structure).
4. 10%: -8–20% if SABR <1.75 and lower-strike put IV re-bids after any credit/dilution scare.

Oracle: IV/price divergence vs 1.85/1.75 tends to forecast the next leg.
