Bullish Case: VST at $149.58 sits well below both Helium's density peak (~$152.5-155) and the market-implied peak (~$155), implying upward drift. Contango term structure (Helium 36-38% near-term vs market 42-45%) and a bullish risk tilt (+8% calls over puts, 43% call-volume excess) support a grind toward $155-160. The $4.2B DOE loan, Meta/AWS PPAs, and Goldman's PJM bullishness anchor contracted cash flows through 2027 guidance of $7.4-7.8B EBITDA.

Bearish Case: VST is -22.9% YoY and just -7.9% on the week despite the DOE loan rally fading — the Oct 6 pop was event-driven and mean-reverts. Helium's return surface shows fat left tails down to -48%, and Helium IV (58-62% Nov 7-14 uncertainty bands) exceeds market IV near-term, signaling elevated downside repricing risk. ERCOT forward softness pushes 2027 toward guidance's low end, and the $4.2B loan remains conditional, unfunded.

Potential Outcomes:

1. Grind higher to $155-162 (35%) — density-mass pull toward $152.5-155; falsified by close <$147.
2. Range $148-155 (30%) — contango theta decay, low volume (3rd percentile) suggests drift; falsified by IV spike >55%.
3. Pullback to $140-147 (20%) — DOE-loan pop unwind, ERCOT softness; Helium puts at 53-55% IV price this.
4. Slide below $140 (10%) — macro/SPY vol stress or interconnection-pause headlines; falsified by 11/20 put IV collapse.
5. Breakout >$165 (5%) — loan funding, Comanche Peak milestone.
