Bearish COIN 330P expiring 9/19/2025

A notable options trade in COIN (Coinbase) shows a significant bearish position being established through a large put sweep. The trade involves the $330 strike put expiring on September 19, 2025, approximately 2 months away. The put option was bought above the ask, signaling urgency and intent. The trade occurred with a spot price of $379.66, meaning the put is currently out-of-the-money by about $49.66.

The volume for this contract is 1,498 contracts. Compared to an open interest (OI) of 3,467, this results in a V/OI ratio of approximately 0.43. While this doesn’t confirm new positioning alone, it does indicate a meaningful influx of new interest relative to existing positions. Notably, the premium paid totals $1.8 million, with each contract purchased at $13.37, across a size of 1,325 contracts. The sweep order type further emphasizes aggressive buying behavior, often linked to institutional activity. This combination of large premium outlay and urgency in execution suggests a strategic hedge or speculative bet on downside movement in COIN’s price over the near term.

Volume and Open Interest Data

Bearish COIN 330P expiring 9/19/2025 Volume and Open Interest Data

The options activity for the COIN $330 put expiring September 19, 2025 shows a major surge in volume on July 28th, 2025. Specifically, 3,345 contracts traded hands — a massive increase compared to previous days. This spike in volume was accompanied by a modest rise in open interest (OI), which increased by 46 contracts to 3,467. This suggests that much of this volume may have involved opening new positions, though not all.

The contract price also surged from $10.17 to $13.93. This implies that the premium rose sharply in tandem with the increased activity, potentially reflecting growing bearish sentiment or volatility expectations. Despite the elevated activity, the implied volatility (IV) stayed relatively stable, ending at 61.24%. The stable nature of IV could indicate that this move was more directional than volatility-driven. Overall, the data suggests institutional-sized buying interest in short-dated COIN puts, potentially as a hedge or speculative play on downside risk.

Trade Side Distribution

The trade side distribution for the COIN $330 put expiring on September 19, 2025 reveals a strong directional bias in put buying activity. 65% of the premium ($1.8 million) executed above the ask while the remaining 35% ($935.4K) occurring at the bid. No trades were executed at the ask, below the market, or at the mid. This strongly underscores the urgency of the aggressive above-ask buys.

The distribution suggests that buyers were highly motivated, willing to pay a premium to secure their positions, a hallmark of institutional or high-conviction activity. The dominance of above-ask executions supports the notion of increased bearish positioning or protective hedging. This aligns with the elevated volume observed in recent trading.

Additional bearish sentiment on COIN was found across the trading tape today. Specifically, a sizable bearish position was initiated in COIN via the $345 put option expiring August 22, 2025. The trade suggests short-term downside protection or speculation. The order involved the purchase of 1,626 contracts at a price of $8.57, totaling a premium outlay of $1.4 million. The trade was executed above the ask, indicating urgency and strong conviction from the buyer.

Notably, the order type is a sweep, which suggests the buyer was willing to execute across multiple exchanges to fill the order quickly. As observed before, this a common tactic for institutional players. With the spot price at $387.69, this put is out-of-the-money by $42.69. The volume (1,628) is significant relative to the open interest (2,084). This skew yields a volume/open interest ratio of ~0.78, signaling a strong burst of new activity. This trade, paired with the elevated premium and aggressive execution, reinforces a bearish or hedged outlook on COIN.
