Two hundred invited guests at the Hugh James Exchange organised by the Cardiff law firm voted overwhelming in support of the proposal that it has achieved the business beacon status since it opened in 1999.
The "yes" vote was recorded by 94 per cent of the 200 strong audience at the Exchange which was addressed by the Group Chief Executive of the Welsh Rugby Union, Roger Lewis.
He said: "This year alone we attracted 61,000 people to the Oasis concert, 124,000 to two Take That concerts and 73,000 to the U2 concert. That was the biggest rock concert attendance ever in Wales.
"Speedway attracted 40,000 people, live on Sky and shown around the world, Monster Jam with almost 30,000 people was screened across the USA. The point I am emphasising here is the economic benefit of major non-rugby events the Stadium presents.
"Over 300 events have now been held at the Stadium since operations began, attracting over 10.6 million paying customers; or an average over one million paying customers per annum. It is by far the largest visitor attraction in Wales."
Fellow Exchange panellist, Mike Hall, the former Wales international and current Director of PMG Developments, said: "After the M4 or the barrage I struggle to think of another project that has generated so much value for Cardiff."
