US Open Under Fire: Jessica Pegula Slams Betting Sponsorship Double Standard

The tennis world is currently focused on the prestigious US Open, but a debate about ethics and integrity is brewing off the court. Jessica Pegula, currently ranked world number three, has issued a sharp warning. At the center of the criticism is the decision by the United States Tennis Association (USTA) to bring on the prediction market Kalshi as an official partner for the 2026 tournament. This agreement makes Kalshi the first Official Prediction Market Partner in the tournament's history, aimed at ushering in a new era of fan engagement. However, for the athletes on court, this development feels like a slap in the face.

Pegula argues that a double standard is at play. While major tournaments fill their coffers with revenue from the gambling and prediction industries, players have their hands tied. Strict anti-corruption rules in tennis categorically forbid professionals from gaining personal advantages through connections with betting providers. While this regulation serves to protect the sport's integrity, it creates a financial imbalance that Pegula has now publicly addressed. In a press conference following her second-round win, she voiced her frustration, pointing to the psychological burden that comes with the constant presence of betting advertisements.

Numbers and facts

The scale of the problem is backed by alarming statistics. A joint report by the WTA and World Tennis shows that sports bettors are a primary source of digital hate. During the 2025 season, gamblers were responsible for 42% of all verified online abuse directed at professionals. In cases of particularly severe abuse, this share even rose to 59%. These figures clarify that social media hate is not a marginal phenomenon but a systemic issue closely linked to the betting market. Pegula emphasized that players feel this negativity constantly, regardless of whether they win or lose their match.

Other professionals, such as Matteo Berrettini, have also spoken out. Berrettini recently revealed that his family received death threats during Roland Garros, directly linked to sports betting. He called for stronger protections for players, especially younger talents who often lack the psychological resilience to handle such massive intimidation attempts. The USTA maintains that the partnership with Kalshi includes strict safeguards to preserve sporting integrity, but for those affected, a bitter taste remains.

Background

Kalshi differs from traditional bookmakers in that it functions as a prediction market. Users trade contracts on yes-or-no outcomes, which is often legally classified differently than classic gambling in the US. Nevertheless, the principle for the end consumer is similar: one bets money on the outcome of a sporting event. The USTA sees this as an opportunity to increase fan engagement via digital platforms and on-court signage. The fact that this is happening at a time when discussions about player protection and match-fixing are gaining momentum worldwide is causing significant friction.

“Players can’t do anything off of a betting type of sponsorship. But the tournaments profit off of a lot of that stuff. We get a lot of hate for it on social media. So, it’s tough when you see that, and then they’re a big sponsor.” - Jessica Pegula, WTA Professional Athlete

Why it matters for German players

For German tennis fans and casual bettors, this international debate has direct relevance to the domestic market. In Germany, the State Treaty on Gambling 2021 (GlüStV 2021) is the ultimate standard. Anyone wishing to bet on tennis in Germany should do so exclusively with providers listed on the so-called whitelist of the Joint Gambling Authority of the States (GGL). These licensed providers must follow strict rules, such as the cross-provider deposit limit of 1,000 euros per month, monitored via the LUGAS system. Furthermore, a stake limit of 1 euro per spin applies to online slots, highlighting the focus on player protection.

Pegula's criticism reminds German players how important a regulated environment is. While international markets often advertise aggressively, the GGL in Germany focuses on prevention. Illegal providers from Curacao or Malta may offer higher limits but lack comparable player protections and often fail to pay out winnings in case of a dispute. Those who want to be safe should only use platforms with a German license, as this also ensures connection to the OASIS lockout system. This protects not only the player's wallet but also indirectly the integrity of the sport, as licensed bookmakers work closely with authorities to prevent match-fixing.

What it means for GGL-licensed casinos

For licensed operators of online slots and sports betting in Germany, this development means increased sensitivity towards sponsorship and social responsibility. The GGL strictly monitors how advertising is placed to protect vulnerable groups like minors or those at risk of gambling addiction. The US Open debate shows that the industry is under global scrutiny. German providers who adhere to the rules of the GlüStV 2021 can position themselves as a serious alternative. By communicating transparently and implementing consistent player protection, they can regain the trust lost due to aggressive practices in the gray market.
