Fans are being challenged to predict #WhosGonnaWin the 98th Running of the Indianapolis 500 Mile Race through an interactive social media campaign sponsored by Verizon.

Through Twitter and www.WhosGonnaWin.com, fans are invited to cast their vote by using the hashtag #WhosGonnaWin with the name of the driver they believe will take home the checkered flag in "The Greatest Spectacle in Racing."

One fan who correctly predicts the winner will be randomly selected to receive a visit from the 2014 Indy 500 champion accompanied by the Borg-Warner Trophy and a show car. Additional prizes will also be given to the contest winner. Other fans who correctly guess the race winner will be randomly selected and awarded prizes, and the driver earning the most fan votes will have $33,000 donated to his or her charity of choice.

Voting for #WhosGonnaWin begins ends when the command to start engines is given May 25. A full list of rules and regulations are available at www.WhosGonnaWin.com.
