Altenar rejects Sportradar’s Swiss arbitration push

• Altenar opposes Sportradar’s motion to relocate their New Jersey antitrust case to arbitration in Zurich.
• The dispute centres on Sportradar’s control of NBA, NHL, MLB and ATP data under a 2021 partnership agreement.
• A related antitrust claim against Sportradar from data firm Sportscastr settled in February 2026.

Altenar has confirmed it will contest Sportradar’s attempt to move their antitrust dispute out of the US District Court for the District of New Jersey and into private arbitration in Zurich.

The Malta-based sportsbook technology provider sued the Nasdaq-listed data giant in March 2026, accusing it of abusing its position as principal data supplier to major US sports leagues and the ATP tour.

Data at the centre

Altenar’s original complaint, filed in the New Jersey court, accuses Sportradar of restricting access to data supplied by the NHL, NBA, MLB and ATP. Altenar says that data is essential to price and operate its sportsbook services in the US.

The claim alleges the conduct breaches Section 2 of the Sherman Act, restricting competition in the market for live official league data. The complaint states:

“Sportradar is trying to maintain its market dominance by unfairly eliminating its competitors. It is relying on its monopoly on sports data to squash businesses with a competing offer, despite previously decrying other companies for doing exactly the same.”

The New Jersey case runs alongside a parallel UK claim Altenar filed in London’s High Court, where Altenar is represented by Geradin Partners.

Home-turf dispute

Sportradar has asked the New Jersey court to send the dispute to arbitration in Switzerland, citing a binding clause in a master partnership agreement (MPA) the two companies signed in 2021.

Sportradar is headquartered in Switzerland, and Altenar’s lawyers argue the move is designed to keep proceedings away from US courts and public scrutiny.

Altenar maintains the antitrust claim belongs “in federal court, not private arbitration in Zurich.” In a court filing, Altenar’s lawyers wrote:

“Sportradar is entitled to arbitrate the disputes it actually agreed to arbitrate. It is not entitled to use the MPA as a shield against the Sherman Act in the very market the agreement carved out.”

Altenar is represented by Cahill Gordon & Reindel LLP in the US and is seeking an injunction along with damages worth several million dollars, a figure yet to be disclosed.

Not the first fight

Altenar’s case is the second antitrust challenge brought against Sportradar in two years.

In March 2025, data firm Sportscastr (PANDA Interactive) expanded a patent lawsuit against Sportradar and Genius Sports to include anti-competitive claims, accusing both of locking data access behind product purchases.

That case, overseen by Judge Rodney Gilstrap in the US District Court for the Eastern District of Texas, was settled in February 2026 after Sportscastr and Sportradar reached an agreement, according to court records.

Altenar argues the pattern is compounded by Sportradar’s own market position. The company has simultaneously launched its turnkey sportsbook platform ORAKO and owns betting tech supplier NSoft, both of which compete directly with Altenar for operator contracts.

Sportradar has continued expanding its league data footprint elsewhere, including a multi-year deal supplying Kalshi with official league data.

Radio silence

An Altenar spokesperson, told SBC News:

“Sportradar’s global headquarters are in Switzerland; it feels safe there. Its motion to send this case to confidential Swiss arbitration is a transparent attempt to shield itself from US justice and public scrutiny. Altenar looks forward to its day in court.”

A spokesperson for Sportradar said the company “does not comment on pending litigation.”

The Nasdaq-listed group, whose backers include the Canadian Pension Plan Investment Board alongside investors Michael Jordan and Mark Cuban, has faced heightened scrutiny this year, including a 23% share price drop following short-seller allegations in April, which prompted CEO Carsten Koerl to publicly reject the claims as an unfounded attack.

A ruling could land either way. New Jersey’s judge may keep the case in open court, or send it behind closed doors to Zurich under the 2021 agreement.

Sportradar isn’t the only gatekeeper of official league data, but it’s one of the biggest. How this plays out could loosen or tighten that grip for every sportsbook and prediction market chasing the same feeds.
