A notable options trade was observed for SPY involving a large bearish position. Specifically, a put option with a strike price of $610, expiring on August 15, 2025, was bought above the ask price, indicating urgency and/or conviction. The spot price of SPY at the time of the trade was $627.08, placing this put out-of-the-money. The trade type was a Sweep, often used to gain quick execution across multiple exchanges and signaling a strong directional bet.
The trade involved 4,572 contracts at a premium of $3.88 per contract, totaling approximately $1.8 million in premium paid. The total volume for the day was 6,080 contracts. Compared to an open interest of 64,482, this results in a Volume/Open Interest (V/OI) ratio of approximately 0.094. While the V/OI ratio is modest, the size and execution style of the trade suggests a large institutional player potentially hedging or speculating on downside risk.
This sweep order, aggressive pricing, and sizable premium make it a noteworthy bearish signal to watch for short-term SPY movement.
Volume and Open Interest Data
Historical data shows significant and sustained trading activity in the SPY 610 Put options expiring August 15, 2025, particularly over the last several sessions. Daily volumes have remained elevated. They’ve peaked at 10,426 contracts on July 22nd, 2025, while open interest (OI) has steadily climbed from 63,802 on July 18th to 64,482 on July 22nd. This indicates new positions are being opened rather than closed. The steady increase in OI (+2,610 on July 18th alone) alongside rising volume supports the view that this is accumulation rather than profit-taking.
Meanwhile, the option price has declined from $4.00 to $3.35. However, implied volatility (IV) remained relatively stable, suggesting a potential fade in bearish sentiment. This could also be due to underlying price movement rather than volatility shifts. Overall, this data points to ongoing institutional activity building a sizable bearish position. Steadily rising volume-to-OI confirms strong market interest in this short-dated put.
Trade Side Distribution
The trade side distribution for the SPY 610 Put expiring August 15, 2025 reveals a clear bullish bias in bearish positioning—a seemingly paradoxical but insightful observation. A dominant 67% ($1.8 million) of the total premium traded was executed above the ask. This indicates aggressive buyers eager to enter the trade, likely expecting further downside in SPY. An additional 15% ($396.2K) traded at the ask, further confirming buyer dominance.
Only 19% ($493.4K) traded at the bid, with zero activity at the mid or below bid. This further strengthens the conviction that buyers are actively targeting this strike despite the contract being out-of-the-money. This skew toward “Above Ask” activity often signals institutional accumulation. In this specific case, it likely reflects a high-conviction bearish bet or a strategic short-term hedge.
Dark Pool Transactions
The dark pool transaction data for SPY on July 22, 2025, reveals three large block trades totaling over $15.8 million in notional value. All occurred within a very short time window. The trades include:
- 10,000 shares at $627.88 for $6.3M at 12:07 PM,
- 7,820 shares at $629.08 for $4.9M at 1:30 PM, and
- 7,378 shares at $628.65 for $4.6M at 1:44 PM.
The consistent high-volume execution and tight price range near $628–$629 suggest institutional positioning. Such positioning likely had strategic intent rather than passive flow. These trades occurred as large SPY put sweeps were also being executed. These coinciding events potentially signal hedging activity or positioning in anticipation of future downside. When analyzed alongside the options flow, these dark pool prints strengthen the bearish outlook, pointing to increased institutional interest and tactical maneuvering behind the scenes.
