The three-time NBA champion announced that he became an investor last September, making him the latest high-profile figure to own a stake in the Tractor Boys.
Haslem joins singer Ed Sheeran among the club’s celebrity investors, adding another global name to Ipswich’s ownership group.
The former basketball star shared the news with fans through a post on Instagram.
"Basketball has been my life, but I’ve always respected the culture and impact of football.”
"Proud to announce that last September, I became a minority owner of Ipswich Town Football Club.
"When I first saw the club’s motto “Running Towards Adversity” I knew this was a club I wanted to be part of. Something I’ve believed in my entire career. Then I met the people behind the club, and it became clear it was more than just words. It’s who they are. That’s the only kind of culture I want to be around.
"I’m excited to support what’s being built at Ipswich…both on and off the pitch.
"Miami to Portman Road. NBA to the Premier League. Let’s go, Blues! “
