A significant options trade was spotted for OPEN (Opendoor Technologies Inc.). The trade was a large bullish call sweep with a strike price of $5 and an expiration date of August 15, 2025. The position involves an order at the ask, further suggesting aggressive bullish intent. The trader purchased 2,002 contracts at a price of $1.78, totaling a premium of $358.4K. Notably, the total volume for this strike is 50,488 contracts. Compared to an open interest (OI) of just 4,045, this yielded a very high V/OI ratio of approximately 12.48. This strongly indicates that most of the volume is from new positions rather than the closure of existing ones.
With less than a month until expiration, this short-dated option trade reflects confidence in a substantial upside move in OPEN. The spot price at the time of the trade was $4.73. This deems the strike to be slightly out-of-the-money (OTM), which adds to the directional conviction. The use of a sweep order type further confirms urgency and an intent to fill quickly across multiple exchanges.

The chart and historical data for the OPEN $5 Call expiring 08/15/2025 shows a dramatic surge in volume. On July 21st, 2025, 51,542 contracts traded hands in a single day. In stark contrast, the open interest (OI) sat at 4,045 contracts. This disparity between volume and OI yields a Volume/Open Interest (V/OI) ratio of over 12.7.

This strongly suggests significant market expectations for a large move in the underlying asset. This volume surge, particularly with virtually no prior open interest, reinforces the view that institutional-sized bullish bets are being placed aggressively for a short-dated upside move in Opendoor Technologies Inc.
