Coinbase Global, Inc. ended at USD 164.51, a decrease of 4.42%.

Large option activity showed a dominant bear call spread collecting $173,900 across the 182.5/190 call strikes, both expiring in 2026. The trade sold premium above spot and pointed to institutional expectations for capped upside. Overall call flow slightly outpaced puts, but the notable bulk-order was entirely a short-call structure, reflecting fading confidence in a sustained rally well into next year.

Options Indicators

COIN’s implied volatility stands at 66.24%, while its IV percentile is 23.11%, indicating that although the absolute IV level is still high, it sits near the lower end of its own historical range. In other words, current option pricing is relatively cheap compared with where COIN options have traded over the past year, and the IV/HV ratio of 0.70 suggests implied volatility is running below realized volatility rather than at a premium. The Call/Put volume ratio is 1.09, showing only modestly higher call activity despite the bearish large trade, which suggests retail or smaller order flow still retains some upside interest while institutional-sized positioning leans defensive.

Large Trades

A call credit spread collecting $173,900 was the standout large trade, structured as a same-direction double-sale call combination with the short 182.5 call and short 190.0 call, both expiring on 2026-09-18. With COIN referenced at $164.51, both strikes were out of the money, making this an out-of-the-money bear call spread designed to collect premium through time decay while expressing the view that the stock is unlikely to rally above the short-call zone by expiration. The trade was established for a net credit of $173,900, which points to a neutral-to-bearish stance: the seller benefits most if COIN stays below 182.5 and, more broadly, if upside remains contained rather than accelerating.

Overall, the bulk-order flow leans bearish. The only highlighted large trade was a premium-selling call spread placed entirely above the current stock price, which suggests traders are comfortable fading upside and positioning for COIN to remain range-bound or rise only modestly into expiration. The absence of offsetting bullish large trades reinforces the message that institutional-sized activity is currently skewed toward restrained upside expectations and a mildly negative directional outlook.

Strategy Reference

For traders sharing the bearish view but seeking lower margin requirements than the double-sale structure, a 185/195 call credit spread expiring in 2026 could capture a similar premium-selling profile while capping loss above the upper strike. Sellers preferring a higher probability of profit may select the 200 strike short call, which sits further out of the money and lowers assignment risk, though it also reduces the net credit received.
