The source told AFP that the choice made by the administrators in charge of Ilva must still be approved by the government's economic development ministry.
Ilva was nationalised and placed under special administration in 2015 after the Riva family, which owned it, was accused of failing to prevent toxic emissions from spewing out across the southern city of Taranto.
The government quickly opened a tender for the steelworks which used to produce a third of the nation's output, wanting to keep the facility open in an area that suffers from high unemployment.
The ArcelorMittal-led offer was nearly 2 billion euros (USD 2.2 billion), according to Italian media.
ArcelorMittal and Marcegaglia have an agreement with the Italian bank Intesa Sanpaolo that it will join the consortium if their offer is approved.
ArcelorMittal has promised to invest 2.3 billion euros into Ilva in addition to the purchase price. Some 1.1 billion euros will go towards environmental cleanup while 1.2 billion will go into production improvements.
