Growth in the Asia-Pacific region will be most important at a rate of 14 percent annually, largely due to the casino developments in Macau. The U.S. will remain the largest gambling market, and is likely to grow by 6.9 percent per year, from $53.4 billion in 2005 to $74.5 billion in 2010, according to the report.

The report also predicts a growth of the online gambling market by 100% from an estimated $5.1 billion this year to $11.4 billion by 2010.

Other markets identified for high growth are the UK, where new gambling legislation will lead to an estimated growth of 16.8 percent a year from $3 billion in 2005 to $6.6 billion in 2010.

New regulation for casinos will likely lead to an increase of the gambling markets in Singapore, Japan, Taiwan and Thailand.
