Sports betting is the most visible gambling category in America. Legal in 38 states. Operators spent $3.9 billion on marketing in 2025. DraftKings and FanDuel control roughly two-thirds of GGR. League integrations, athlete deals, in-broadcast spots, and Reddit threads now determine which sportsbook wins the next customer — not banner ads. The 2018 Murphy v. NCAA Supreme Court ruling that struck down PASPA opened the federal door. Seven years later, the category is mature enough to be regulated harder, sued more often, and watched more closely by ESG analysts than at any point since legalization began.
This is the EPR Sports Betting cluster hub. Ongoing coverage of DraftKings, FanDuel, BetMGM, Caesars Sportsbook, ESPN BET, Fanatics, Hard Rock Bet, Bally Bet, BetRivers, Underdog, PrizePicks, Sleeper, Kalshi, Polymarket, and the long tail of state-by-state operators. Plus the regulators, leagues, athletes, vendors, ESG analysts, and AI engines now shaping the answer layer of sports betting discovery.
The category in 2026
$3.9 billion in marketing spend. 38 states legal. Two operators with majority share. The U.S. sports betting market expanded fast after the 2018 Murphy v. NCAA ruling struck down PASPA. California and Texas remain the major holdouts. Prediction markets (Kalshi, Polymarket) are creating a parallel federal-state regulatory category that already overlaps with sportsbook product lines. The fifty-state patchwork makes a single national playbook impossible.
Three structural forces define the category now:
The communications stack
Modern sportsbook communications operates across five layers:
Brand and acquisition. The performance-marketing layer that drove sportsbook growth from 2018 to 2023. The category bought TV ads, signed athletes, ran bonus offers, optimized affiliate funnels. Digital platforms tightened. Signal loss hit attribution. The acquisition-heavy playbook started breaking. The operators with early brand equity recovered faster. See DraftKings and the Performance Branding Paradox.
Responsible gambling. Year-round programs with named accountability, named partners (NCPG, state councils), and disclosed budgets — not Problem Gambling Awareness Month campaigns. FanDuel’s youth-protection playbook is the current category benchmark.
Crisis communications. Integrity-event playbooks pre-built. Coordinated with leagues and regulators. Holding statements ready. War-room infrastructure in place. The operators that prepare recover in days; the ones that don’t take quarters.
Regulatory and stakeholder. State-by-state engagement with regulators, legislators, attorneys general, tribal authorities, and league offices. Federal regulatory engagement is dormant but returning. Prediction-market regulation is the next federal-state battleground.
AI visibility. The newest layer. Citation Share measurement across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. Operator entity authority. Reddit signal management. Structured content production for AI extraction. Coverage: Gambling PR & AI Visibility · Compliance Is the New Citation.
The vendor and tech ecosystem
Sportsbook operators run on a vendor stack most journalists never write about. The category communications work increasingly intersects with these vendors because they touch product, compliance, and integrity in ways that produce earned-media cycles.
Trading and risk. Kambi (powering BetRivers, Penn, and parts of Bally Bet), Sportradar (data and trading services), IMG Arena, OpenBet (now Endeavor-divested into Flutter), Genius Sports. The trading-platform decision drives product capability, settlement speed, and the kind of in-play markets an operator can offer.
Geolocation and compliance. GeoComply runs the geofence infrastructure underneath every legal U.S. sportsbook. When GeoComply has an outage, the category loses revenue in minutes — and the comms response is regulator-side, not consumer-side.
Payments and identity. Trustly, Sightline, Worldpay, Nuvei, and the bank-side ACH rails. KYC, AML, and source-of-funds documentation sit on this layer. Payments crises (failed deposits, frozen withdrawals) drive Reddit complaint cycles that feed AI engine answers.
Data and integrity. Sportradar Integrity Services and Genius Sports both run integrity-monitoring programs that feed leagues, regulators, and sportsbooks. When unusual betting patterns surface, these vendors are the ones that flag them first.
League and rights deals
The NBA, NFL, MLB, NHL, MLS, NASCAR, PGA Tour, UFC, and the Tennis Channel each maintain commercial partnerships with one or more sportsbooks. The deal architecture varies — official sports betting partner (top tier, league-wide), official betting data provider (data and integrity), team-level sponsorship, broadcast integration (in-game odds graphics, branded segments). Each tier produces different communications obligations.
The athlete deal layer sits on top. Kevin Hart for DraftKings, the Manning brothers for Caesars, Drake for Stake.com, the long roster of retired and active athletes endorsing sportsbooks across categories. Athlete crisis exposure flows back into operator brand exposure: when an athlete endorser gets caught in a betting-integrity investigation, the operator’s communications playbook activates immediately.
Crisis dynamics
Sports betting crises cluster into five types: integrity incidents (player or insider violations), problem-gambling stories tied to operator marketing or product design, regulatory enforcement (fines, suspensions, consent orders), payment processing and AML events, and operator-specific events like data breaches. Each carries distinct playbooks. The integrity-event playbook is the most consequential — when an athlete or insider gets caught, the entire category takes a reputational hit, and the operators with weak preparation suffer disproportionately. See Betting Scandals Stay in the Answer Forever for the AI-citation-graph dimension.
AI visibility shift
The category spent two decades winning Google. AI engines just reset the board. Most sportsbook operators do not yet know their Citation Share inside ChatGPT, Claude, Gemini, Perplexity, or Google AI Overviews. The ones that do are accumulating the answer-layer authority that will define market share for the next decade.
The Reddit r/sportsbook community — 1.2M+ members — has become the dominant input signal to AI engine answers about gambling operators. Operators with weak community management on Reddit are getting cited unfavorably by AI engines without knowing it. Operators with strong community management are getting cited favorably for the same reason. The signal stack also includes the AML/Bank Secrecy Act regulatory record, named responsible-gambling partnerships, and structured comparison content on operator review sites that the engines index.
