Bitcoin options open interest hits 34.5 billion

Bitcoin options positioning has turned sharply defensive ahead of the June 26 quarterly expiry, with total open interest reaching about $34.5 billion and downside protection dominating across markets.

Bitcoin is trading near $63,000, roughly 50% below its October 2025 peak of $126,000, as traders brace for potential volatility tied to a large wave of expiring contracts.

Derivatives skew signals downside risk

Put activity and trading volumes have climbed to multi-year highs, reflecting strong demand for protection against further declines. More than 70% of outstanding put contracts are positioned to profit from moderate price drops, reinforcing a bearish structure.

Between $57,000 and $61,000, put exposure exceeds $3 billion, while another $2.7 billion sits between $61,001 and $65,000. In contrast, nearly 78% of call options are struck above $72,000 and remain out-of-the-money, leaving them at risk of expiring worthless unless Bitcoin rallies more than 14% before settlement.

One major derivatives platform controls about 79% of global market share, with roughly $13 billion in contracts expiring this week alone, concentrating risk into a narrow time window.

Institutional markets reinforce cautious stance

Data from the Chicago Mercantile Exchange show put open interest has exceeded calls since November 2025, with positioning heavily concentrated in near-term maturities. Earlier this year, 25-delta put implied volatility surged to 95%, signaling that regulated traders were aggressively pricing downside risk.

The 25-delta risk-reversal indicator has remained negative since August 2025, indicating persistent demand for protective puts even during periods of price recovery.

Spot market flows weaken support

ضغط in derivatives markets is unfolding alongside weakening demand in spot markets. U.S. Bitcoin ETFs have recorded continuous outflows since mid-May, including roughly $6.4 billion withdrawn over the past month.

At the same time, total options and futures open interest has dropped significantly from October highs of $65 billion and $90 billion, respectively, to about $35 billion and substantially lower levels in futures.

This decline suggests reduced participation and thinner liquidity, limiting the market’s ability to absorb large positioning shifts.

Macro uncertainty adds pressure

Broader market conditions remain unsettled as Federal Reserve policy expectations shift. A more hawkish outlook, including reduced expectations for rate cuts and the possibility of further tightening, has weighed on liquidity-sensitive assets such as Bitcoin.

Higher yields in traditional markets are drawing capital away from risk assets, adding to the headwinds already visible in derivatives and spot flows.

Expiry dynamics highlight key price levels

Options pricing models point to a “max pain” range near $77,500 to $78,000, well above current prices. Other trading venues estimate a lower range between $66,700 and $69,000, underscoring uncertainty over where Bitcoin could gravitate into expiry.

The gap between current levels and these estimates highlights the scale of repositioning required to shift the current bearish structure.

Outlook remains fragile into expiry

Traders are watching three key pressures into the end of the quarter: the concentration of roughly $13 billion in expiring contracts, the continued dominance of protective puts, and sustained ETF outflows reducing demand.

Unless spot prices rebound sharply or capital flows stabilize, Bitcoin is likely to remain under short-term downward pressure as the market navigates one of its largest recent expiry events.
