There’s no doubt the Super Bowl crowds showered Indianapolis with cash all week. The question is, how much of it will stick after the big game is over? And how much will it mean to Indianapolis’ economy?

An estimated 150,000 visitors were expected to spend roughly $150 million in Indianapolis, according to projections by the Indianapolis Convention & Visitors Association and PricewaterhouseCoopers. And with record crowds showing up, those numbers could end up being even higher.

In normal circumstances, those dollars would swirl through the Indianapolis economy, producing other spending that pushes the economic impact to $300 million or $400 million.

The Super Bowl, however, is anything but normal. Many sports economists say much of the money spent here will disappear faster than a zipline rider whizzing over Capitol Avenue. That could reduce the true impact to $100 million. But even the millions the Super Bowl crowds spend will be a drop in the bucket compared with the $105 billion in goods and services produced every year in the Indianapolis metro area. So expect the benefits of the game to be more emotional than economic.

Indianapolis leaders insist the Super Bowl will prove to be a big economic win: in direct visitor spending, in boosting the city’s image, and in attracting more convention and tourism business.
