Bitcoin Options Expiry Clears $16B in Open Interest; Traders Eye $95K

September 25 Expiry Clears Massive Notional Open Interest

Bitcoin's September 25 quarterly options expiry on Deribit cleared roughly $15.6 billion in open interest, according to Bitcoinist reporting. The settlement occurred as Bitcoin traded around $83,600, below the week's near-$87,000 high but remaining well above its earlier trading range. However, the size of the notional figure masked a smaller and less visible question: which contracts actually produced payments. Exchange rules determine what a winning holder receives, but those rules do not retroactively clarify the pre-expiry mechanics that shaped which positions were genuinely exposed.

Market Context and Altcoin Momentum

Bitcoin's position near $84,000 after the September expiry came as XRP and Solana continued outperforming BTC over the week despite the large derivatives settlement. The divergence suggests that while Bitcoin remained stable through the options clearing, capital was rotating into alternative Layer 1 tokens, at least over that seven-day window.

Traders Position for End-of-Month Rally

With the quarterly expiry behind them, traders are now building large butterfly spread structures betting on Bitcoin hitting $95,000 by the end of October. Butterfly spreads—a multi-leg options strategy that profits in a narrow band around a target price—suggest positioning for a moderate rally rather than a sharp breakout. The concentration of these bets at the $95,000 level indicates traders view that price as a credible near-term target over the next 30 days, roughly an 11% move from current spot levels.
