AGA Reports 4.6% US Gaming Revenue Growth As Prediction Markets Challenge Sportsbooks

Casino floors carried the market. The verticals built for the next decade did not.

US commercial gaming revenue rose 4.6% year on year in May 2026, according to the American Gaming Association’s Commercial Gaming Revenue Tracker published on 16 July. The growth was almost entirely land-based. Sports betting revenue fell 1.8% to $1.34 billion, its second contraction of the year, and state sports betting tax receipts declined 2.4%. The AGA attributes much of the pressure to prediction market platforms operating outside state regulatory guardrails. The industry has spent the year celebrating milestones, from record quarters to the people shaping them, with the latest Gaming Hall of Fame class honouring four of its long-standing figures. This month’s data is a reminder that the celebration and the pressure are running side by side.

The numbers behind US commercial gaming revenue May 2026

Traditional casino gaming expanded 4.5% to $4.68 billion. Slot machines produced $3.39 billion, up 4.6%. Table games added $933 million, up 3.9%.

Sports betting handle came in at $12.06 billion, down 0.4%. Strip out Missouri, a market that did not exist a year ago, and handle fell 2.7%. Hold dropped 16 basis points against May 2025, which compounds the problem: less money staked, and less of it kept.

iGaming reached $1.03 billion, up 14.7%. Still the fastest growing segment in the US. Still slowing, month after month, because no new state has come online since 2024.

Regulated gaming delivered $1.53 billion in state gaming tax revenue, up just 0.7%. That figure lands very differently once you see it against the record totals the sector was posting only a few quarters ago, tracked in our earlier report on the AGA’s US commercial gaming revenue record. The trajectory has clearly flattened.

The competitor that does not pay tax

Here is the line that will get quoted in every state house this autumn. Kalshi alone handled nearly $15 billion in sports betting volume in May. Every regulated US sportsbook combined handled $12.06 billion.

The AGA estimates prediction market platforms have deprived state governments of over a billion dollars in gaming taxes since the start of 2025, with seniors’ pension plans and responsible gaming programmes among the funds affected. Skill machines and so-called sweepstakes casinos sit in the same untaxed bracket.

What US commercial gaming revenue May 2026 means for operators

Licensed sportsbooks are absorbing tax, compliance cost, responsible gaming obligations and marketing restrictions while a parallel product takes handle with none of it. That is not a customer acquisition problem solvable with a better free bet. It is a cost base problem.

For CMOs, the practical read is that state-by-state CAC models built on 2023 assumptions are now carrying a competitor those models never priced in. For founders and platform heads, the question is whether to lobby, litigate, or build into the category. Several large operators have already signalled the third option. That tells you something about their confidence in the first two.

The caveat worth holding

Hold volatility is real and one month proves nothing on its own. May is a thin sporting calendar. A run of favourite-heavy results can move national hold by more than 16 basis points without any structural cause at all.

But handle is the cleaner signal, and handle is falling on a like-for-like basis. Punters are staking less in regulated books. That is harder to explain away with a bad month of results.

Future outlook

Watch three things over the next six to twelve months. First, whether any state successfully asserts gaming tax authority over prediction market sports contracts, which would set the precedent everyone else follows. Second, whether iGaming growth can survive another year without a new state, because the current deceleration curve reaches flat somewhere in 2027 without one. Third, the September to January window. Football season is when the volume gap becomes politically impossible to ignore.

The land-based floor saved the headline this month. It will not be asked to do that forever.
