BetMGM trims 2026 revenue outlook as prediction markets bite

BetMGM cut 2026 revenue guidance and kept Adjusted EBITDA unchanged after a Q1 update exposing how much pressure prediction markets are putting on regulated US sportsbooks. The Entain-MGM JV posted Q1 net revenue of $696 million (up 6% YoY), with iGaming at $481 million (+9%) doing the heavy lifting while OSB was pressured by unfavourable sports results and higher acquisition costs. Q1 EBITDA was $25 million; FY EBITDA $300–$350 million was maintained but flagged at the lower end.

What changed in the guidance?

BetMGM lowered its top-line to $2.9–$3.1 billion while keeping EBITDA at $300–$350 million, signalling a pivot toward defending profitability over chasing revenue. Q1 net gaming revenue per active player rose in iGaming and exclusive content deals helped retention, but OSB faced materially higher customer-acquisition costs. The trade-off is clear: less inefficient OSB marketing, more spend on higher-return areas to protect EBITDA.

Why prediction markets are inside the story

The most consequential line in the BetMGM update is the explicit reference to “competitors positioning as ‘prediction markets'” inflating CAC. That ties the operator’s quarterly miss directly to the regulatory and competitive arc covered in our analysis of how iGaming and prediction markets defined Q1 2026 gambling earnings. The cheap interpretation is competitive crowding; the harder reading is that prediction-market venues (Kalshi, Polymarket, others) are buying the same paid-search and creator-channel inventory regulated sportsbooks rely on, lifting the cost-per-acquired-customer for everyone. That has been a structural backdrop for US sports betting since late 2025 and BetMGM is the first major operator to put a guidance-level number on it.

Chief executive Adam Greenblatt framed the quarter as on-track strategically despite the OSB headwind:

“Although it has been a steady start to the year, BetMGM is delivering on our strategic plan, carrying forward the initiatives that drove our transformation in 2025. We are generating sustainable, profitable growth and paying cash to our parent companies. Our iGaming business is growing at scale, and our online sports business continues to strengthen despite a challenging market in Q1.”

How peers and the wider sector should read it

For the broader US gaming sector, the BetMGM cut is a leading indicator that the prediction-market-versus-sportsbook competition is now visible in quarterly results. Expect DraftKings, FanDuel and ESPN BET to address CAC pressure on their next calls. The same backdrop is fuelling consolidation talk, including the ongoing Fertitta-led $7 billion takeover bid for Caesars. The pattern: when revenue growth slows but iGaming runs, operators either defend EBITDA (BetMGM) or pursue M&A (the Caesars track).

What happens next

Three observable markers will resolve how the year plays out. First, BetMGM’s Q2 update — whether the OSB CAC line stabilises or worsens; flat is good news, another step up is a warning. Second, the Alberta launch on July 13, 2026: a clean opening with strong early registrations would offset some of the OSB drag and is the most concrete near-term catalyst. Third, regulator and Congressional action on prediction-market event contracts — any CFTC restriction or legislative reclassification of sports event contracts would directly relieve the CAC pressure that just cost BetMGM a guidance step. Until those signals land, the BetMGM update is the cleanest evidence yet that the prediction-market boom is not a sportsbook-adjacent story; it is a sportsbook-economics story.
