just before going on-air that a format change would be implemented shortly, but was asked not to use the opportunity to say goodbye to listeners. Instead, mid-show, Thompson was signaled to give a final station identification; the station then began a stunt loop featuring songs and promotional announcements referring to betting, money, and winning. The promotions stated that a new format, billed as "the most unique radio station in the Bay Area", would launch on October 10, assuring listeners that they "can bet on it". On that day, KGO launched a sports talk format emphasizing sports betting, branded as "810 The Spread"; the new format has no local programming, and the station's schedule is primarily sourced from the BetQL and CBS Sports Radio networks, serving as a complement to sister sports stations KNBR-FM and KTCT. Sports KGO was the radio broadcast home for the San Francisco 49ers football team from 1987 to 2005. It has broadcast UC Berkeley Golden Bears Football games since 1974; since 2013, it also broadcast select California Golden Bears men's basketball games. The station began to air San Jose Earthquakes soccer games in 2023.

Listeners were encouraged to call in and donate money to help in the fight against these kinds of cancer. An auction was also held to help raise money. Notable items up for auction have included a trip with Gene Burns on a private jet to various destinations, such as Las Vegas and Italy, for a gourmet dinner. Cumulus Media has announced that it will not be continuing the KGO Cure-a-Thon charity event despite the fact it has raised millions of dollars for charity in the past. Solar power In March 2008, solar panels were installed at KGO's transmitter site in Fremont, California, to offset some of its power consumption during daytime hours. The effort is a testbed for Pacific Gas and Electric Company and is located near the Dumbarton Bridge. The solar system uses both CPV (SolFocus) and PV (Premier Power) arrays and provides about 17 Kilowatts, or 33% (one third), of the radio frequency (RF) power output from the 50KW transmitter (or about one-tenth of the total
