If not, we securely run geocoding batches of that size at Geocode Earth all the time at pretty competitive rates. We are flexible on data transfer, usually we have customers set up an SFTP server or an S3 bucket and send us the credentials. We spin up a ton of hardware in EC2 to geocode it real fast (<24 hours even for a few hundred million addresses), will work with any data format you need, and then send it back.
If you _do_ need to run it locally, we're also the creators of the Pelias geocoder(https://pelias.io), which is open source like Nominatim but supports more than just OSM data (which is not a comprehensive address source globally), so often can return better results. We can help you set it up if you need.
