The financial services industry (including three major sub segments: investment services, banking and insurance) led all vertical markets in server revenue, as it accounted for 25.1 percent of worldwide server revenue in 2006, according to Gartner.

The communication market was a distant Number two segment for server revenue with 13,5% of global server revenue, and the government market was the Number three vertical with 11,5% of total server revenue.
"The financial services market has been the investment leader for all IT spending and the server market is no exception," says Kiyomi Yamada, senior research analyst at Gartner. "In 2006, many financial institutions faced challenges for operational risk management and regulatory requirements. This led to structural changes, and this, in turn, resulted in more server sales."
IBM was the leading vendor in the financial services market, accounting for 44,6% of server revenue in 2006. Hewlett-Packard was the second vendor in this market with a 26,7% market share, followed by Sun Microsystems in third place.
