Amazon is suing the Defense Department to overturn the award, potentially worth $10 billion to Microsoft.
In an email, public affairs officer Lt. Col. Robert Carver did not rule out the possibility that the award would be overturned, only the possibility that it would be split.
There was speculation earlier in the month that a court motion signaled the possibility to divide the contract between Microsoft and Amazon.
The Defense Department had filed a formal motion asking that certain technical aspects of the award to Microsoft be reconsidered, because a judge ruled some questionable.
The Pentagon awarded the contract to Microsoft Azure in October. Many thought the favorite was Amazon Web Services, which had created a similar common cloud for the CIA and other intelligence agencies.
