In 2005, Jupiter Research forecast that global mobile gambling services would generate revenues of more than $19.3 billion US dollars by 2009. In 2010, Gartner analysts showed the 2009 global mobile gambling revenues at $4.7 billion and forecast $5.6 billion for 2010. Such a large discrepancy between the 2005 forecast and the 2009 reality is attributed to the unexpected 2006 US prohibition of all internet based gambling.
The mobile gambling market, as of 2011 is still in flux. The European Union still does not have a unified mobile gambling legislative framework in place.

According to a Juniper Research report released in September 2010 the total sum wagered on mobile casino games is expected to surpass $48 billion US dollars by 2015. The report bases this prediction on (1) the high growth rates of mobile casinos, lotteries and sports betting providers in major emerging markets and China; (2) liberalization of mobile gambling legislation in Europe; (3) United States repealing the Unlawful Internet Gambling Enforcement Act of 2006, permitting people in the US to legally gamble online again.
A 2010 Gartner forecast sees 2014 global mobile gambling revenues reach $11.4 billion dollars.
