The firm informed something similar also happened to gaming revenue during the last World Cup, four years ago.
Last month Wells Fargo said the trend was for annual growth in gaming revenue to be between 13 percent and 15 percent, but that annual growth would have to be 17.5 percent this month if it was to reach 14 percent in the second quarter of this year.
Nomura Securities predicts that gaming revenue this month will be US$2.92 billion, 12.2 percent more than a year ago.
