[Bitcoin Traders Await $15 Billion Options Expiry, Bulls Eye $100,000] According to a report by Bitcoin Magazine on September 25, as cited by Jinse Finance, approximately $15 billion worth of Bitcoin options are set to expire during the quarterly settlement on Friday (September 25). Contracts expiring on September 25 account for over one-third of Deribit's total open interest in BTC options. Market sentiment leans bullish: the put-to-call ratio is 0.70, with the largest call positions concentrated at strike prices of $85,000, $90,000, and $100,000. Bitcoin is recently trading around $84,258, down 2% on the day, but still significantly above the "max pain" price of $76,000 and just below $85,000 (the most concentrated call strike). The market is watching whether this level will act as resistance before expiry. The article notes that large expirations are often accompanied by volatility, but market makers' hedging can help mitigate this. Recent strength has been driven by factors such as the U.S. Treasury expanding buybacks, a weakening dollar, and Bitcoin breaking above its 365-day moving average.
