It’s no secret that championship rings can spur huge economic boosts for winning cities. Boston and Seattle, the respective homes of Super Bowl LX contenders, stand to benefit from such upswings after the game on Feb. 8.

But are home values a part of that economic phenomenon? According to Zillow, yes: The site’s Home Value Index shows that in 13 of the past 20 years, home values in the metro area of the Super Bowl champion grew faster than the national average, increasing by an average of $4,437 more than typical United States houses in the year following a championship win.

Both Seattle and Boston have benefitted from this trend in the past: When the Seahawks won the Super Bowl in 2014, Seattle home values increased by $13,667 more than the national average in 2015; when the Patriots won the very next year, Boston home values increased by $14,832 more than the national average the following year.

The city with the biggest boost was Tampa, though: When the Buccaneers won in 2021, average home values increased by $25,262 more than the national average in 2022.

However, Zillow analysts say homeowners in Seattle and Boston shouldn’t expect too much of a value boost if their city hoists the trophy on Sunday.

“While this is a fun trend, it’s highly unlikely that a championship football team is the driving force causing home values to grow,” Senior Economist Kara Ng said in a press release. “Regardless of the outcome, the good news is that we are trending toward a healthier market nationwide, with more homes for sale and buyers better able to afford them.”
