It's very expensive. But $5 billion in tax incentives helps:
"the report warns that the city’s new 467-m tax break may be overly generous, potentially costing $5.1 billion in lost property tax revenue over 37 years".
That's just too speculative. My viewpoint has always been no tax breaks on stadiums, headquarters, etc, but you just can't know what'll happen. At least if you give the break you have somewhat of idea that they'll be more incentivized
