The Milwaukee Bucks player — who once had money in dozens of bank accounts — is teaming up with Calamos Investments on an ESG fund.

The NBA superstar who once had cash in 50 different bank accounts is now involved in the world of exchange-traded funds. 

Milwaukee Bucks forward Giannis Antetokounmpo is working with Illinois-based Calamos Advisors on an ETF that will invest in sustainable companies. 

The new Calamos Antetokounmpo Sustainable Equities Fund will allow investors to bet on the performance of firms adhering to environmental, social and governance standards determined internally. It will exclude any involved in activities including animal testing, gambling, nuclear energy and alcohol, according to a filing. 

Calamos declined to disclose if Antetokounmpo had seeded the fund.

“The shared values between Calamos Investments and Giannis Antetokounmpo forge the foundation for a great partnership,” a representative for Calamos said in a statement. 

Antetokounmpo, a two-time most-valuable player known as the “Greek Freak,” is close with Avenue Capital Group founder Marc Lasry, who co-owns the Bucks.

Lasry said in April that Antetokounmpo had more than four dozen bank accounts, with each of them holding up to the Federal Deposit Insurance Corp. coverage limit, before Lasry stepped in. 

Anthony Tursich and James Madden — portfolio managers at Calamos Investments — will manage the ETF’s investments. Both are alums of Portfolio 21 Investments, an early leader in sustainable investing.
