The US government is offering to buy a controlling stake in an off-lease Miami-based audio streaming service for as little as $400 million, Bloomberg reported.

The bidding process is expected to end next week, with bids expected to be in the hundreds of millions of dollars, the news agency reported.

A bid could be the most expensive off-the-shelf audio service on the market, Bloomberg said.

The service, dubbed AudiLease, is currently available in the US but the government wants a stake in order to further expand its reach into Latin America and Asia.

In the deal, Audi leases the rights to a number of audio and video assets to a company it acquired in 2014, including rights to music, movies and other assets.

Audi will also own a portion of the service’s revenue.

The sale of the rights would be financed by an investment from the government.
