Giannis Antetokounmpo stayed put at the trade deadline. However, that did not stop him from making a headline-grabbing move away from the court.

On February 6, 2026, the Greek Freak announced that he is investing in Kalshi through his personal company, Ante Inc. The announcement immediately raised questions across the NBA and sports business world. What exactly is Kalshi, and why is one of the league’s biggest stars putting his name behind it right now?

Antetokounmpo confirmed his involvement through a company press release and his social media account, marking his first direct investment in a federally regulated financial trading platform. “I love the Kalshi markets and have been checking them often recently,” Antetokounmpo said. “I like to win. It’s clear to me Kalshi is going to be a winner, and I’m excited to be getting involved.”

The investment comes shortly after the February 5 trade deadline passed with Milwaukee keeping its franchise cornerstone. While Giannis remains focused on his on-court return from a right calf strain, this move shows his growing interest in long-term business positioning beyond basketball.

What Is Kalshi and How Does It Work?

Kalshi operates as a federally regulated exchange overseen by the Commodity Futures Trading Commission. Unlike sportsbooks such as FanDuel, DraftKings, or BetMGM, Kalshi is classified as a derivatives market rather than a gambling platform.

Because of that distinction, Kalshi is available nationwide across the United States.

On the platform, users trade “Yes” or “No” contracts tied to real-world outcomes. Prices range from 1 cent to 99 cents, reflecting the market’s perceived probability of an event occurring. If the outcome is correct, the contract settles at $1. If it is wrong, it settles at $0.

Importantly, users trade against other users, not the company itself. Kalshi collects transaction fees but does not take positions on outcomes, functioning more like a stock exchange than a sportsbook.

Markets span economic data, political outcomes, and sporting events, with sports-related contracts generating the majority of user engagement.

Is Kalshi Legal and Regulated in the United States?

Kalshi’s federal approval allows it to operate across all 50 states under CFTC authority, bypassing the state-by-state licensing model required for sportsbooks.

That said, the platform has faced challenges from several state regulators, including New Jersey, Nevada, Massachusetts, and Maryland, who argue that sports-based contracts conflict with local gaming laws. Kalshi continues to contest those claims by asserting federal jurisdiction over derivatives trading.

The exchange was founded by MIT graduates Tarek Mansour and Luana Lopes Lara and is backed by investors including Sequoia Capital and Charles Schwab. Its regulatory framework includes safeguards against insider trading, manipulation, and deceptive practices.

Why Did Giannis Antetokounmpo Invest in Kalshi and What Does It Mean for the Brand?

Antetokounmpo’s involvement brings immediate credibility and visibility.

With a global following exceeding 20 million across social platforms, his backing strengthens Kalshi’s public profile during an ongoing period of regulatory scrutiny. The company has confirmed that, as an active NBA player, Antetokounmpo is prohibited from trading on NBA-related markets under its terms of service.

“As an active player in the NBA, Antetokounmpo will be forbidden from trading on markets related to the NBA,” Kalshi stated, citing its insider trading and integrity policies.

This partnership reflects a broader trend of elite athletes pursuing ownership stakes rather than traditional endorsement deals, a move permitted under NBA collective bargaining rules that allow players to hold up to 1 percent ownership in outside ventures.

Has Giannis Antetokounmpo Invested in Other Startups Before?

Kalshi is not Antetokounmpo’s first step into the business world. In 2024, he launched Build Your Legacy Ventures, a fund focused on early-stage companies in sports, entertainment, and technology. That initiative made its first investment in Unrivaled, a women’s three-on-three basketball league founded by Breanna Stewart and Napheesa Collier.

He also holds minority ownership stakes in the Milwaukee Brewers, Nashville SC, and the LA Golf Club, expanding his influence across multiple professional sports. For now, Antetokounmpo remains sidelined with a calf injury while Milwaukee looks ahead to the rest of the season. Off the court, though, his Kalshi investment signals a clear direction.

Rather than waiting for retirement to build his portfolio, Giannis is positioning himself inside emerging sports-adjacent financial markets while still at the height of his NBA career. As Kalshi continues to grow and defend its regulatory standing, his involvement adds both star power and legitimacy at a critical moment.
