Coinbase closed at $145.45, up 5.53% from the prior session.
The session’s large options trades skewed clearly bearish. A single block print dominated the tape: a $812,000 purchase of long-dated puts at the 125.0 strike. With spot at $145.45, this was an out-of-the-money position, and the size points to institutional positioning for material downside or portfolio hedging rather than a simple short-term sentiment trade.

Options Indicators
Coinbase currently has an implied volatility of 73.30%, and with an IV percentile of 54.98%, its volatility sits in a neutral historical range rather than at an extreme. Combined with an IV/HV ratio of 1.15, this suggests the options market is pricing in somewhat higher forward volatility than recent realized movement, but overall option premiums are not especially cheap or especially expensive relative to Coinbase’s own recent history.
The Call/Put volume ratio is 1.61, indicating that across the broader options complex, call volume outpaced put volume. However, this ratio is dominated by smaller retail-sized orders and does not offset the bearish signal from the large institutional put block. Traders should treat the call/put ratio with caution when large-trade flow is pointing the other direction.
Large Trades
A PUT buy worth $812,000 targeted the 125.0 strike expiring on 2026-12-18, with 1,400 contracts purchased. With COIN referenced at $145.45, this option was out of the money at the time of the trade, making it a relatively lower-cost bearish position that needs a meaningful downside move to gain substantial intrinsic value. Strategically, this kind of single-leg put purchase points to outright downside speculation or portfolio protection, and the buyer was clearly positioning for weakness in COIN over a longer-dated horizon.
Overall, the large-trade flow in COIN was bearish. The only displayed block was a long put position, and the absence of offsetting bullish large trades suggests traders using size were focused on downside exposure rather than upside participation. Taken together, the bulk-order activity indicates cautious to negative sentiment, with expectations tilted toward a decline in COIN or a need to hedge against that risk.
Strategy Reference
For traders who agree with the bearish institutional signal but want to avoid paying for expensive long-dated premium, a bear put spread may be preferable. For example, buying the 125.00 put and selling the 100.00 put in the same 2026-12-18 expiration would reduce upfront cost while still capturing downside toward the lower strike. Alternatively, if a trader is neutral-to-bullish and believes the institutional put was simply protective flow, selling an out-of-the-money put below major support near 110.00 with closer-dated expiration would offer a low assignment probability while collecting elevated premium from the 73.30% IV environment.
