Oracle is set to shun the United States and hold the next America's Cup in Europe.

It's understood there isn't the financial willpower in the US to stage the regatta with the State of California broke.

Commentator PJ Montgomery says Larry Ellison is also poised to announce the Cup will not be raced in mono-hulls.

He says we should know in the next couple of months that the America's Cup will be raced in multi-hulls in La Maddalena in Italy.

Montgomery says there could be a small revolution from challengers on Oracle's hands.

He says Team Origin has already indicated it is not interested in multi-hulls.
