Just from what I saw on the stream, I pulled out of left field that the total cost of the entire event, from build out of the rooms, to production, to hiring staff, website, prize fund, etc, to be 3 million USD.
I have it from a good source that almost $10 million was spent on tables, rooms, lighting, electronics, referees, camera crew, production, hotels, transportation, prize money, scorekeepers, announcers, Internet bandwidth, etc.
No expense was spared.
I wish that a live audience had been present, but given the venue, that was not possible.
Maybe next year.
