It's still 10 months before opening, but naming rights partner is already announced. SoFi is said to have agreed the most expensive contract of all NFL stadia. No wonder, the stadium has unprecedented price tag, too.

Just a month after Allegiant Stadium naming rights deal was announced in Las Vegas, the second superstadium under construction has secured its partner. And, just like the difference in scale, there is supposedly a difference in contract value that gives Los Angeles supremacy.

Official information includes only the duration of newly-formed partnership, expected to last 20 years. Unofficial estimates suggest, however, that it's also the most expensive deal to date. Given what we've seen in Las Vegas and Arlington, this means a sum upwards of $20 million per annum.

Even if true, it's still a relatively low percentage of the entire stadium's budget, possibly around 12%. At present SoFi Stadium is expected to cost $3.4 billion itself and somewhere around $5 billion including the surrounding complex.

Initilly it was planned that the stadium would open in 2019 but rainy early months of the construction process pushed inauguration date until August of 2020. That date has also changed more recently, seeing two Taylor Swift concerts become opening events in July of 2020.

Even without the pop star SoFi Stadium already has an impressive calendar. Along NFL games of Chargers and Rams the venue will host the 2022 Super Bowl, college football national championship game in 2023 and opening/closing ceremonies of the 2028 Olympics. During these top events capacity of the stadium should just slightly exceed 100,000.
