Candlestick Park
Plans were underway to construct a new 68,000-seat stadium at Candlestick Point. On November 8, 2006, however, the 49ers announced that they would abandon their search for a location in San Francisco and begin to pursue the idea of building a stadium in Santa Clara. As a result, San Francisco withdrew its bid for the 2016 Olympics on November 13, 2006, as its centerpiece stadium was lost. Groundbreaking for the Santa Clara stadium occurred on April 19, 2012. On May 8, 2013, the media announced that the name of the new stadium would be Levi's Stadium. The stadium opened on July 17, 2014, in time for the 2014 NFL season. The 49ers christened their new home a month after it opened.
Oakland Raiders
There had been discussions for the Raiders to share Levi's Stadium with the San Francisco 49ers. However, the 49ers went ahead without the Raiders and broke ground on the $1.2 billion stadium on April 19, 2012 and have since sold $670 million worth of seats including 70% of club and luxury suites, making it unlikely that the Raiders would continue to explore the idea of sharing the stadium as they would now be secondary tenants with little to no commercial rights over the highly lucrative luxury suites.
