BTC options tilt bullish as calls dominate

TLDR

Bitcoin (BTC) options markets currently show a clear bullish tilt, with call contracts dominating open interest and trading volume on major venues.

1. On Deribit, upside call strikes around 70,000 and 72,000 hold nearly 5 billion dollars of notional open interest, with calls far outnumbering puts.
2. Across the broader BTC options market, calls make up about two thirds of contracts and most recent volume, signaling paid demand for upside even as overall exposure edges lower.
3. The key watchpoints are July and August expiries around these strikes and legislative or macro news, which could turn these levels into price magnets or reversal zones.

Deep Dive

1. Size Of The Bullish Call Cluster

Deribit, the leading BTC options venue, has a concentrated cluster of call positions at the 70,000 and 72,000 strikes that together account for nearly 5 billion dollars in notional open interest, or about 18% of its BTC options book, with calls at these strikes vastly outnumbering puts.

Data cited by Laevitas shows roughly 39,000 calls versus 3,800 puts at 70,000, and about 37,900 calls versus 1,200 puts at 72,000, a heavily skewed call to put ratio that points to strong upside positioning.

Much of this has been built via bull call spreads and outright call buying linked to ethereum/">optimism around the US CLARITY Act, according to a recent analysis of this cluster.

2. What The Bullish Tilt Really Signals

Market wide options data shows BTC options open interest around 33.20 billion dollars, down slightly from the prior day, but calls still represent about 66% of outstanding contracts and roughly 55% of 24 hour trading volume, indicating traders continue to pay for upside exposure even while trimming some leverage.

Spot BTC has pulled back to the mid 60,000s, so the call dominance is less about aggressive new longs and more about maintaining medium term bullish structures while using puts for protection and tactical hedging.

The skew suggests a two track market: investors holding longer dated upside exposure via calls while some flows rotate into shorter dated puts for downside insurance and volatility trades.

3. Levels, Expiries And The Main Risks

On Deribit, the biggest open interest concentrations are upside calls at 70,000, 72,000 and 80,000, with near term expiries on July 31 and follow up activity around August 7, meaning these strikes can act as magnet levels as expiry approaches.

A key risk is that the original driver behind some of these structures, optimism on the CLARITY Act passing soon, has faded as political leaders signal delays, which could see traders further scale back upside bets if legislative progress stalls.

Macro factors such as Federal Reserve policy and ETF flows also intersect with this options skew; a hawkish rates backdrop or sustained ETF outflows could push traders to close calls or lean more on protective puts, reducing the bullish tilt.

Conclusion

BTC options data currently shows a call heavy, upside focused market structure, with large clusters of bullish exposure at 70,000 to 72,000 and calls dominating both open interest and recent volume.

If those call clusters persist and spot BTC drifts higher into key expiries, options positioning could reinforce upward moves, but fading legislative optimism, macro uncertainty and increased put hedging mean the bullish tilt can unwind quickly if sentiment turns.
