The Super Bowl, America’s biggest football event, is set for Sunday at Levi’s Stadium in Santa Clara, California. The Seattle Seahawks face the New England Patriots in a showdown that is expected to boost the San Francisco Bay Area economy by up to $630 million. Thousands of fans will flood the region, spending large amounts on hotels, food, and entertainment. Even fans unable to attend will spend heavily on watch parties and food, driving nationwide spending higher. The National Retail Federation expects Americans to spend a record $20.2 billion on the event, with 79 percent of that going to food expenses. Local reports predict the Bay Area will see between $370 million and $630 million in economic output from this single game. Last year, New Orleans earned $658 million and hosted 115,000 visitors during the Super Bowl. Some costs come with hosting the event. Santa Clara’s expenses are relatively small at an estimated $6.3 million, covering extra personnel and logistics. In comparison, Atlanta’s 2019 Super Bowl cost the city $46 million. Beyond immediate spending, the game also sparks infrastructure improvements. Houston launched its first light rail line just before hosting the Super Bowl in 2004. Las Vegas recently built a $1.9 billion stadium partly funded by hotel taxes to host the 2024 Super Bowl. Experts note the economic benefits tend to be short-term and focused on certain industries and areas. Michael Edwards, sport management professor at North Carolina State University, said, "The economic benefits are relatively short-term, not just in duration, but also in scope. They’re limited to certain industries and specific locations." For consumers, key game-day foods are slightly more expensive this year. Hosting a party for 10 now costs around $140 per person. Chicken wing prices dropped by 2.8%, while dips like salsa rose 1.7%. Vegetable prices and beer are also climbing. NBC, which will broadcast the game, sold out its Super Bowl advertising spots early at a record average price of $10 million for 30 seconds, up from $8 million last year. This surge in ad sales is supported by other sports events like the Winter Olympics. NBCUniversal chairman Mark Marshall said, "NBCUniversal has solidified itself as a sports powerhouse, and brands have taken notice." This big lineup of sporting events has also boosted Comcast’s stock, NBC's parent company, which rose more than 4 percent in the past five days.
