The San Francisco 49ers have already sold three-quarters of the seats at its new Silicon Valley stadium, thanks in part to the team's Super Bowl run.

The 49ers said Friday that fans and corporations have bought $403 million worth of tickets at the Santa Clara stadium that's set to open next year, when the team leaves Candlestick Park in San Francisco.

The new $1.2 billion stadium requires fans to buy seats that cost between $2,000 and $80,000, then purchase season tickets that cost $850 to $3,750 each year. The most expensive seats in the 68,500-seat stadium have already sold out.
