Approximately $1.81 billion in Bitcoin and Ethereum options will expire this Friday, with market positioning clearly favoring bullish outcomes. Coinbase Markets data shows the overall put/call ratio for BTC options stands at 0.66, while the 24-hour volume ratio has dropped to 0.37, indicating accelerated call buying. ETH options reflect similar sentiment with an open interest put/call ratio of 0.61 and a 24-hour volume ratio of 0.55. BTC call open interest is heavily concentrated at the $90,000 and $100,000 strike prices, signaling trader expectations for upside momentum. ETH call interest is more distributed across the $3,000 to $4,000 range. Recent trading activity has leaned further toward calls, particularly in Bitcoin, suggesting derivatives markets are pricing in potential gains ahead of the weekly expiry event.
