Thesis

  • ETH was trading around $2,486-$2,488 on September 8-9, 2026, giving a cushion of about $86 (3.5%) above the $2,400 strike (cites: f1, f2)
  • With ~2.5 days until the noon ET September 11 resolution candle, ETH's realized daily volatility (typically 3-4%) implies a one-standard-deviation move of roughly 5-6% over the horizon, so the strike sits about 0.6-0.7 standard deviations below spot (cites: f1, f2)
  • The resolution is a single 1-minute Binance candle close, which adds minor microstructure noise relative to a daily close, slightly widening the effective outcome distribution
  • The retrieved facts give only a spot level with no trend, positioning, or volatility data, so I cannot adjust away from a driftless random-walk assumption in either direction

Base rate

For a crypto asset sitting ~3.5% above a strike with ~2.5 days to expiry, a driftless lognormal with ETH's typical ~60-75% annualized volatility implies roughly a 70-75% chance of finishing above the strike.

What would prove this wrong

A sharp ETH selloff of more than ~4% over the next two days, e.g., driven by a broad risk-off move or crypto-specific negative catalyst, would flip this market toward NO.
