New Falcons stadium will be located in downtown ATL and owned by the state. The cost continues to rise (Falcons are responsible for all overruns but is currently around $1.2B I believe). The state is kicking in 200M in bonds, which bonds will be repaid by a hike in the hotel tax, which will be paid by mostly plebs from CLT and like townships who come to ATL to see MLB, a real NBA team, Final Fours, and eat meals at real restos.
Once built, the Falcons will pay the city $2.5MM a year for 10-12 days of use.
The GWCCA (Georgia World Congress Center Authority, the state entity that controls the GWCC, the GADome and will control the new stadium), will also be able to rent out the new dome for Final Fours, CFB Championship Games, a Superbowl, the new ATL MLS team, concerts, and all sorts of other high revenue generating events.
Falcons games and the above will also provide hundreds of part time jobs on event days, as well as collateral economic impact.
I am not sure of any other venture in which the city could make a $200M short term loan, and reap the same economic benefits, but I am sure the experts here will tell us otherwise.
