Sportradar's Prediction-Market Inflection Meets Its Brazil Discount

The flywheel finally spins

Sportradar’s third quarter was not a routine beat. “Sport Radar generated revenues of 363 million an increase of 70 million or 24% compared with the third quarter of 2025.” — Craig I. Felenstein, Chief Financial Officer · 2026-11-03 Adjusted EBITDA rose 21% to $102 million, a 28.2% margin, and the company still carries no debt, $190 million of cash, and a fully undrawn $250 million revolver. But the more important line was qualitative: prediction markets moved from pipeline to P&L.

Carsten Koerl framed it directly: “this is the first quarter we saw the benefits of the extension of our flywheel in prediction markets with exchanges.” — Carsten Koerl, Chief Executive Officer · 2026-11-03 That is the change. Polymarket now uses Sportradar across 20 leagues, Kalshi is a partner, Novig is the third exchange, Robinhood is the first broker, and roughly 10 market makers have signed. The product is not generic data resale; it is a prediction market feed built for the lowest possible latency, enriched with deep official data. The regulatory wedge is official data: the NBA recently authorized prediction markets requiring official data, and three of the top four U.S. leagues have cleared Sportradar to supply it.

This is a genuine shift from the prior posture. A year ago Koerl was explicit about the gating factor:

as long as we have not a clarity on this, how the predictive markets are taxed. I think it is very, very difficult for us and for the market to see that we can really invest here.

But the scale is still small. “There are well over 300 market makers” — Carsten Koerl, Chief Executive Officer · 2026-11-03, and Sportradar has roughly 10. One broker is signed. The deals carry fixed and variable components, so the contribution is real but not yet linear. Management is careful not to size prediction markets separately in guidance. The phrase “early innings” is not just modesty here; the contract count says it is true.

IMG, Atrium, and the per-share lever

The other engine is IMG. One year in, integration is running ahead of the original 25% revenue synergy target. Sportradar gets $50 million from IMG this year and another $50 million next year, and it is selling the content through an 800-plus client base that is far larger than IMG’s original distribution. That is why the quarter’s 37% growth in betting and gaming content revenue is not just a rights pass-through; it is the distribution machine working.

The portfolio cleanup is equally important. The sale of Atrium Sports for $170 million removes a non-core coaching and scouting business that made up nearly all of the sports performance revenue line, with standalone EBITDA margins slightly above 30%. That sale will dilute reported growth and margin optics, but it sharpens the story and adds cash. Meanwhile, Sportradar has repurchased 28 million shares for about $408 million year to date — roughly 24% of its beginning free float. At a $4.2 billion market cap, that is not a token buyback. Craig Felenstein was blunt about the logic: “we do believe that there are significant opportunities to repurchase shares” — Craig I. Felenstein, Chief Financial Officer · 2026-11-03. The company is using both the Atrium proceeds and operating cash to lean into the dislocation it sees between its share price and intrinsic value.

Brazil, MLB, and the unchanged guide

So why did the stock story not feel cleaner? Because the guide was unchanged, and the offset is messy. Management reiterated 2026 constant-currency revenue growth of 19% to 21%, or $1.518 billion to $1.538 billion reported, and adjusted EBITDA growth of 24% to 27%, or $360 million to $368 million. That is a strong outlook. But it is not a raise, even with prediction-market revenue arriving for the first time.

The reason is Brazil. The provisional measure signed in September remains in effect while Congress and the Supreme Court weigh the industry’s request for an injunction. Sportradar estimates Brazil-related revenue at a little over $60 million annually. Craig Felenstein sized the near-term modeling impact: “the 60 million that we talked about as a current kind of run-rate annually for the business on the top line side” — Craig I. Felenstein, Chief Financial Officer · 2026-11-03. The cost-out has not started, so if Brazil does not return, there is a revenue hole before there is a savings offset. That is why an otherwise good prediction-market quarter did not become a guidance raise.

MLB is the second exogenous risk. A lockout is possible, and analysts asked about it again. Sportradar’s answer is the same as it was in March: contractual protections exist, and the portfolio can substitute ATP, PGA, WNBA, and other tier-one content. “For us, the impact will be very limited if there is impact.” — Carsten Koerl, CEO · 2026-03-03 That may be true, but it is also the kind of line management has used before. The market will want proof in the Q4 guide, not just contractual language.

The deeper strategic point is that traditional OSB market growth has slowed. Craig said plainly: “Today, the traditional OSB market is growing a lot less than that.” — Craig I. Felenstein, Chief Financial Officer · 2026-11-03 Prediction markets are the replacement TAM. That is also why the rapid expansion is raising competitive intensity, which Sportradar benefits from on the data side but also has to navigate on the regulatory side.

The read-through

Sportradar is no longer selling a prediction-market concept. It is selling a live feed, settlement data, market-maker connectivity, and customer acquisition into a market that Coinbase also flagged as a growth vector on its own call — Prediction Markets are becoming an investable theme, not a novelty. Sportradar sits underneath that theme as a toll road. If prediction-market volumes scale, the incremental margins should be high because the company is reusing the same rights, technology, and teams that already power sports betting.

But this is still a show-me story. The first positive revenue contribution is real. The contract count is not yet large. Brazil could remove a meaningful revenue stream before cost savings catch up. MLB could interrupt a season. And PlayRadar, the 24/7 iGaming channel arriving early next year, is still a startup inside a mature company. Management’s aggressive buyback is the strongest signal that they believe the value gap is wider than the noise. The quarter’s real message is narrower: the prediction-market flywheel has started turning, but the market is not yet willing to pay for it while Brazil and baseball remain unresolved.
