Bitcoin and ether are heading into a closely watched options expiry on Deribit, with traders assessing whether the event could influence price action into the end of the week. The setup is notable not just for its size, but for the gap between current spot prices and the so-called max pain levels, which sit materially higher for both assets.
At the time referenced in the source material, bitcoin was trading at $87,278 and ether at $2,936. Against that backdrop, the upcoming Friday expiry has drawn attention because large open interest remains concentrated at strikes above spot, reinforcing a market structure that still reflects longer-term bullish positioning even as near-term sentiment has softened.
Bitcoin Expiry Size Stands Out
For bitcoin, roughly 150,000 BTC in open interest are set to expire this week on Deribit, representing about $13.19 billion in notional value. The max pain level is $101,000, far above spot, indicating a significant distance between where bitcoin is currently trading and the level where option writers would experience the least aggregate loss at expiry.
The put/call ratio of 0.61 suggests the options market remains tilted toward calls despite recent weakness in spot price. That does not eliminate downside hedging activity, but it does show that bullish positioning still dominates the broader derivatives landscape.
Open interest rankings reinforce that point. The heaviest call positioning for December 2025 expiries is clustered between $100,000 and $140,000. In particular, the $100,000 and $112,000 call strikes each hold more than 15,000 BTC in open interest. On the downside, the most prominent put positioning is concentrated around $85,000, which is much closer to current spot but still less dominant than the large call blocks overhead.
Short-dated trading activity has also remained active. In 24-hour volume rankings, near-term $85,000 puts and $100,000 calls were among the most actively traded contracts. That combination points to a market preparing for volatility while still preserving upside exposure in later-dated structures.
Ethereum Shows an Even Stronger Call Bias
Ethereum’s expiry profile is smaller in absolute dollar terms but still significant. The source material places Friday’s ether options expiry at about $1.66 billion in notional value. Here too, the max pain level is above current spot, with ETH max pain at $3,400 versus spot at $2,936.
The put/call ratio of 0.50 indicates an even stronger call bias in ether options than in bitcoin. This suggests that, while traders are aware of short-term uncertainty, the options market continues to reflect a preference for upside participation.
Open interest is especially concentrated in high-strike calls. The $4,000, $5,000, and $6,000 call strikes each carry more than 50,000 ETH in open interest, according to the source. By contrast, puts are more heavily grouped around the $2,600 and $3,000 strikes, but they do not match the scale of the major upside call clusters.
Over the previous 24 hours, ETH options volume showed relatively balanced activity between calls and puts, although calls retained a slight edge. The most active contracts were concentrated around shorter-dated premiums near $2,650 and $3,000, a sign that traders may be positioning for either a rebound in spot or a volatility spike ahead of expiry.
What Max Pain and Positioning May Signal
Max pain is often watched as a reference point into expiry, though it does not guarantee that spot prices will move toward that level. In this case, both bitcoin and ether have max pain levels that are well above current market prices. That divergence matters because it highlights how options positioning can remain structurally optimistic even when spot prices are trading lower.
For bitcoin, the rising max pain curve above $100,000 aligns with demand for long-dated, higher-strike calls. For ether, sustained growth in options open interest over the year — including during cooler market periods — suggests that participation has remained resilient. The source specifically notes that this pattern may reflect ongoing institutional involvement in ETH options markets.
At the same time, short-dated contracts are seeing meaningful turnover, which points to a market that is not complacent. Traders appear to be balancing two views at once: a willingness to defend or speculate on long-term upside, and a near-term need to hedge against event-driven volatility around expiry.
Why Friday’s Expiry Matters
Large options expiries can affect market tone by influencing hedging flows, short-term positioning, and trader psychology, especially when open interest is substantial and concentrated around visible strikes. With $13.19 billion in BTC notional and $1.66 billion in ETH notional approaching expiry, this week’s Deribit event stands out as one of the more important derivatives milestones in the period covered by the source.
The setup leaves room for multiple outcomes. Spot prices could remain under pressure, drift toward key strike areas, or simply see traders roll positions into later maturities. But regardless of the exact path, the combination of heavy notional value, call-heavy open interest, and max pain levels above current spot suggests this expiry could play a meaningful role in setting the market’s short-term tone into the weekly close.
In short, the derivatives market is signaling a mix of caution and optimism. Near-term volatility risk appears elevated, yet the broader structure in both BTC and ETH options still leans bullish. That tension is likely to keep traders focused on Deribit through Friday’s settlement window.
