Anthopoulos and Jim Hendry were the top remaining candidates, after a source said the Braves moved away from their top target, Royals senior vice president and general manager Dayton Moore, who would have needed permission from the Royals to become Atlanta's president of baseball operations. Anthopoulos was most recently the Dodgers' vice president of baseball operations.
Atlanta has operated without a GM since John Coppolella resigned in October.
Anthopoulos will take over a Braves team looking to reestablish itself as a National League contender.
The investigation is expected to be completed within the next few weeks and the Braves are likely to face heavy penalties including the possible loss of prospects and restrictions on draft and free-agent dealings.

Rain will return on Wednesday and we'll remain with a slight chance of rain showers for the rest of the week ahead. Highs will quickly climb into the upper 50s and low 60's Friday before temps crash behind this front.
The former Toronto Blue Jays general manager and current Dodgers vice president of baseball operations will reportedly end the search for John Coppolella's replacement. He pulled off deals for the likes of Josh Donaldson, Troy Tulowitzki and David Price.
Anthopolous was a scout with the Expos and Blue Jays before becoming one of baseball's youngest-ever GMs.
Anthopoulos, a native of Canada, served as the Blue Jays GM from 2010-2015, after joining the organization in 2003. Sherman said Anthopoulos will make final baseball-related decisions.
The results of the investigation will determine Hart's future. The former Blue Jays GM will be taking over for John Coppalella, who was sacked following MLB's investigation into the team's activities in the global market.
