IBIT options and the new CBOE weekly landscape

IBIT liquidity and fees

I select IBIT for any position I expect to manage because the 0.02% median bid-ask spread beats ARKB’s 0.05%. The 0.25% sponsor fee exceeds the 0.14% charged by MSBT or the 0.15% from Grayscale’s Mini Trust. On a $10,000 position over ten years, the 0.25% fee costs $265 against $149 at 0.14%. However, the liquidity supports more market makers who tighten those spreads. Crossing a spread 0.03 percentage points wider twenty-four times a year costs 0.72%, which overcomes the 0.11 percentage point fee saving of moving to a cheaper fund. IBIT trades over 52 million shares on an average 30-day basis and holds $60 billion in net assets. The fund uses both Coinbase Custody and Anchorage Digital, a federally chartered digital asset bank, to reduce the risk that a single custodian failure causes a total loss of access. IBIT, alongside Fidelity’s FBTC, absorbed 83% of new spot Bitcoin ETF inflows in the first quarter of 2026. IBIT holds four times the assets of the third-largest spot Bitcoin fund. You, the active trader, know that liquidity provides its own value. I still question if the extreme concentration of assets in one fund creates too much systemic risk.

Managing Greeks with CBOE weekly contracts

The November 2026 launch of CBOE weekly contracts changes how traders handle volatility. The $2 billion notional open interest in these contracts shows how participants use Greeks to hedge. Delta measures the sensitivity to the underlying price, while Gamma measures how fast that Delta shifts. A 0.30 delta call implies a 30% chance of expiring in the money. If a call has a 0.52 delta and a 0.07 gamma, a $1 increase in the price pushes delta to 0.59. Theta decay follows an acceleration curve, and it runs 3 to 5 times faster in the final week than at 60 days out. Vega measures how much an option price moves for each 1 percent change in implied volatility. Market makers rebalance approximately every 1 to 2 minutes to maintain delta neutrality. The $2 billion notional open interest in the new CBOE weekly contracts reflects how traders use the Greeks to manage the aggressive time decay of Theta and the rapid acceleration of Gamma as expiration approaches.

Comparing market players

Fidelity’s FBTC faces different pressures as market maker spreads compress in its options market. The SEC delay of the portfolio margin rule creates a different reality for those seeking leverage. I would skip the IBIT fee if I only wanted a set-and-forget IRA. IBIT holds 770,000 BTC, which provides the depth needed for large orders. IBIT ranks as the 11th most liquid ETF in the US with 34,825,921 shares of average volume and the 18th largest by average notional. The SEC may spend up to 240 days reviewing an application before finalizing a digital asset ETF.
