The Bucks – eyeing a first championship since 1971 – suffered disappointment in the playoffs last year, going out in a 4-1 Eastern Conference semifinals series loss to the Miami Heat.
That came after they had finished the regular season with an NBA-best 56-17 record.
The postseason blow prompted speculation over the future of Antetokounmpo, who has been named MVP for two straight years and is out of contract at the end of the 2020-21 season, when he will be eligible for a supermax extension.
Antetokounmpo will not rush to commit to the Bucks, even if he wants to stay, in a move likely to pressure team management to surround him with a stronger supporting cast.
"I do not know what the plan is," Antetokounmpo said to Aftonbladet when asked about his future while on vacation in Sweden.
"It depends on what decisions they make. If they make the right decision, I will be there for many years.
"If they do not, we will see. The NBA is business and we take it day by day. Hopefully we can succeed together.
"There are a lot of rumors. Everyone has opinions. But at the end of the day, I will do what is best for my family."
Antetokounmpo insists his chances of winning championships will always be the biggest factor in his decisions, even though his lucrative extension could range from between $228.2million and $243.7m.
The Greek added: "I do not see why I could not be in Milwaukee for several years.
"As long as Milwaukee and I are on the same page when it comes to being one of the best teams in the league and winning championships, that is fine.
"When it changes, it will not be good. It is easy, I want to be a winner. As long as we can win and create a winning culture, it will be good."
