Bitcoin faces $6.44 B options expiry, key strikes at $75k and $80k

Bitcoin traders are gearing up for the expiration of roughly $6.44 billion worth of BTC options on Deribit at 08:00 UTC on Friday, Aug. 28. The expiry involves about 81,700 contracts, each representing one Bitcoin.

Option composition and strike concentration

There are 44,639 call contracts and 37,061 put contracts, giving a put‑to‑call ratio of 0.83. The largest call notional sits at the $75,000 strike ($236 million) followed by the $80,000 strike ($157 million). More than $500 million of total notional value lies within 5 % of Bitcoin’s current market price.

Potential market impact

Deribit’s chief risk officer notes that the tight concentration near $75k‑$80k could trigger increased gamma‑hedging activity as the price approaches these levels. Depending on dealers’ net positions, hedging could either pin Bitcoin near a strike or amplify moves through it.

Volatility dynamics

Approximately 20 % of Deribit’s open interest is set to expire, and the Deribit Bitcoin Volatility Index (DVOL) rose about 30 % over the prior week. The volatility term structure shifted from backwardation to contango, and the call‑put skew moved from negative to positive, indicating higher implied volatility for calls.

Price context and max‑pain level

At the time of reporting, Bitcoin traded near $78,970, down 1.4 % over 24 hours but up 22.9 % over seven days. The max‑pain estimate sits around $68,000, but Bitcoin is trading roughly $11,000 above that level, and max‑pain is not a reliable price target.

What to watch

• Whether Bitcoin holds near the $80,000 strike, slides toward $75,000, or breaks through the clustered strikes.
• Potential intraday volatility spikes as dealers adjust hedges.
• Post‑expiry volatility contraction once short‑term hedging demand eases.
