Wow $2.9 billion global mainframe market ... that's almost 3% of the US federal government IT budget excluding Defence in 2022 ($74 billion). Gartner forecasts global IT spend in 2023 of $4700 billion (yes, just under $5 trillion). Maybe mainframe will reach 0.1% of that. Of course mainframe is soooo much more cost efficient, hence the very low $ spend needed for mainframe :)
