As of today the top ten most active stock option contracts traded are listed below (from most traded to least).
- Citigroup (C) August 3 Call Option
 - Citigroup August 5 Put Option
 - Citigroup December 3 Call Option
 - Citigroup August 3 Put Option
 - Citigroup August 5 Call Option
 - Plains All American Pipeline, L.P. (PAA) August 45 Call Options
 - SPDR Financial (XLF) August 12 Call Options
 - SPDR S&P 500 (SPY) August 100 Call Options
 - Citigroup August 10 Call Options
 - Citigroup September 4 Call Options
 
The reason Plains All America Pipeline 45 Call options were among the most active is most likely a dividend play, as they spin out $0.905 a share tomorrow. However I find it very strange that the Citigroup Inc. (C) 10 strike August call options were among the most active today.
