Prior comparison unavailable: the published 2026-09-06 edition is verified but ends at 6 Sept, 16:59 UTC; this window requires 6 Sept, 16:54 UTC.
A structured watchlist was not recorded or could not be verified in the prior edition; prior-watch outcomes remain unavailable.
Next daily cutoff: measurable checks
These checks are reconstructed from this edition’s stored endpoints; they were not recorded in the original report.
Hold the observed level: SOL 1W ATM IV ≤ 53.53 percent at . Current level 53.53; threshold is the current observed endpoint.
Full retrace: SOL 1W ATM IV ≥ 54.67 percent at . Current level 53.53; threshold is the previous observed endpoint.
Measurement basis and receipt
These are observed-level conditions for the next aligned cutoff, with no forecast or trade action. Spot uses exact index endpoints where available; ATM IV is quoted in percent and its change, RR25 and BF25 in volatility points. Derived from verified legacy artifact endpoints.
RR25 moved towards puts, averaging -2.32 volatility points to 1.27 volatility points across the four available headline tenors. Negative RR25 denotes a richer 25-delta put wing under the call-minus-put convention.
BF25 was broadly unchanged, averaging +0.06 volatility points to 4.23 volatility points across the four available headline tenors. BF25 measures the average 25-delta wing premium over ATM IV.
Contracts with fewer than 2 full days to expiry remain in the tables but are excluded from headline rankings. Settlement proximity, time decay, changing liquidity and fewer quotes can exaggerate their changes.

Completed-session cross-asset context
Crypto volatility against US equity risk.
SOL 30-day implied volatility was 3.5 times VIX, while its 30-session return correlation with SPX was low at 0.25.
Implied-volatility premium
SOL 30-day ATM IV was 50.73%, against VIX at 14.53: a 36.20-point spread and 3.49× ratio.
Realised-volatility regime
SOL reported crypto realised volatility was 76.48%, versus SPX reported realised volatility of 8.30%. The spread ranked at percentile rank 59.5% of 222 prior observations.
Equity co-movement
Return correlation with SPX was 0.252 over 30 aligned sessions and 0.383 over 60 sessions. VIX9D, VIX and VIX3M closed at 11.97, 14.53 and 17.61.
RV comparison basis unverified: this edition does not record the recognised provider methodology for both horizons and annualisation conventions. The displayed spread rank does not establish matched-horizon comparability.
As of 04 Sept 2026, 20:00 UTC. Implied volatility and completed-session realised volatility use their respective observation windows shown above.
Changes use these stored market-snapshot baselines. The comparison baseline may differ from the snapshot used in the previous published edition.
Original report summary
Solana options shifted toward puts: Solana’s one-week RR25 fell 3.33 volatility points to -0.14 volatility points, leaving one-week put volatility richer than call volatility. Solana’s front-end ATM IV across the one-week, two-week and one-month tenors averaged 53.18%. Solana’s front-end ATM IV fell 0.62 volatility points. Solana’s one-week ATM IV fell 1.14 volatility points to 53.53%. Long-dated comparable tenors were unavailable.

Current surface characteristics
Where normalized model Greek intensity is highest.
These are comparable Black-forward Greeks for a one-SOL ATM-forward call at each listed expiry—not portfolio exposure, open interest or a prediction of dealer positioning.
Thresholds are asset-specific policies recorded in this edition. Each window is assessed independently; returns spanning gaps are excluded. Partial estimates may miss volatility during gaps.

Fixed tenors
Fixed-tenor measures are published only when listed expiries bracket the target at both comparison snapshots. Targets outside either observable range are suppressed, not extrapolated; headline rankings use only supported tenors.
Smile reconstruction
Listed-expiry smiles are reconstructed from stored SVI total-variance parameters on a fixed log-moneyness grid.
Ultra-short expiries
Expiries with fewer than 2 full days remaining stay in detailed tables but are excluded from headline rankings. Settlement proximity, time decay, changing liquidity and fewer quotes can exaggerate their changes.
