BetMGM is the third-largest US sportsbook, backed by MGM Resorts and Entain’s combined infrastructure. Its prop offering stands out for three features competitors don’t match: Edit My Bet (live parlay modification), cross-sport parlays, and MGM Rewards integration that converts betting volume into real-world hotel and dining rewards. The trade-off: BetMGM’s vig escalates on lopsided lines more than FanDuel or DraftKings, and winner treatment follows industry norms. For agents, BetMGM provides a solid third data point alongside DraftKings and FanDuel for cross-book prop comparison.
BetMGM at a Glance
BetMGM is the third-largest legal sportsbook in the United States by gross gaming revenue, trailing FanDuel and DraftKings. It operates as a 50/50 joint venture between two giants: MGM Resorts International — the Las Vegas-based casino and hospitality empire — and Entain (formerly GVC Holdings), one of the world’s largest online gambling operators headquartered in the UK.
The joint venture was signed on July 30, 2018, just weeks after the Supreme Court struck down PASPA in May 2018 and unlocked legal sports betting nationwide. Both parents invested an initial $100 million each. The logic was straightforward: MGM brought the brand recognition, the physical footprint across 30+ US resorts, and regulatory relationships; Entain brought the sports betting technology platform, trading expertise, and decades of online gambling operations in Europe.
BetMGM posted $2.8 billion in revenue for 2025, a 33% increase over 2024, split roughly $1.82 billion from iGaming and $903 million from online sports betting (up 63% year-over-year). More importantly, 2025 marked BetMGM’s first profitable year — adjusted EBITDA flipped from a $244 million loss in 2024 to a $220 million profit, a $464 million swing. The venture returned $270 million in cash to its parent companies in Q4 2025 and is targeting $500 million in adjusted EBITDA by 2027.
As of March 2026, BetMGM Sportsbook is legal in 23 states plus Washington D.C. and Puerto Rico: Arizona, Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Mississippi, Missouri, Nevada, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, Washington D.C., West Virginia, and Wyoming. Missouri was the most recent launch on December 1, 2025.
BetMGM commands approximately 13% of US sportsbook gross gaming revenue — firmly third behind FanDuel (~44%) and DraftKings (~34%). Within iGaming specifically, BetMGM holds a stronger 21% market share, reflecting the strength of MGM’s casino brand in states where online casino is legal.
Why BetMGM for Props
BetMGM’s prop value proposition isn’t about having the deepest menu (DraftKings wins that) or the tightest vig on every line (FanDuel edges it on lopsided markets). BetMGM’s advantages are structural and experiential.
Edit My Bet is the standout differentiator. No other major US sportsbook lets you modify a live parlay — swapping legs, adding picks, increasing stakes, or removing a losing selection — without tearing the whole ticket apart. If you build a five-leg One Game Parlay and one leg looks doomed by halftime, BetMGM lets you surgically remove it. DraftKings forces you to scrap and rebuild.
Cross-sport parlays let you chain prop bets from entirely different sporting events — an NFL player prop with an NBA total with a Premier League goal scorer — on a single ticket. DraftKings and FanDuel have added versions of this, but BetMGM’s implementation was early and remains well-integrated into the app experience.
MGM Rewards integration is the physical-world edge. Betting activity on BetMGM earns MGM Rewards points redeemable across MGM’s 30+ resort properties — Bellagio, Aria, MGM Grand, Borgata, Beau Rivage, and others. For anyone who visits Las Vegas or Atlantic City, this loyalty loop adds tangible value that no pure-play digital sportsbook can replicate. Hotel rooms, dining credits, show tickets, and spa access convert your betting handle into real-world perks.
Lion’s Boost promotions offer daily enhanced odds on pre-selected props and parlays. These are BetMGM’s version of odds boosts — the house takes a reduced margin on specific featured bets, typically tied to marquee matchups. Lion’s Boosts are among the best recurring promotions in the industry for prop bettors, often offering genuinely positive expected value on the boosted line.
Prop Bet Types on BetMGM
BetMGM’s prop architecture follows the same core taxonomy as every major US sportsbook — player props, team props, game props, and novelty props — with BetMGM’s particular strengths showing in futures markets and cross-sport combinations.
Player Props
The heart of BetMGM’s prop offering. Player props are wagers on individual statistical performance within a game.
BetMGM structures player props in three primary formats:
Over/Under lines — BetMGM sets a statistical threshold and you bet whether the player exceeds or falls short. Example: Luka Doncic over/under 31.5 points. The most common and most liquid player prop format.
Yes/No props — Binary outcomes. Will Derrick Henry score a touchdown? (Anytime TD Scorer.) Will a pitcher record 8+ strikeouts? BetMGM also offers First TD Scorer and Last TD Scorer at longer odds.
Head-to-head matchups — Two players paired against each other on a specific stat. Who records more receiving yards: Ja’Marr Chase or Amon-Ra St. Brown? No spread, no total — just the head-to-head comparison.
Team Props
Wagers isolating a single team’s performance. BetMGM offers team totals (Eagles over/under 27.5 points), first team to score, team to reach a scoring threshold first (first team to 20 points), team total touchdowns, team sacks, and team turnover props.
Team props are valuable for bettors who have a view on one side but not the game total. The game total might sit at 48.5, but BetMGM’s team prop lets you bet the Lions specifically over 24.5.
Game Props
Structural events within the contest involving both teams. BetMGM’s game prop menu includes: overtime (yes/no), total field goals, both teams to score 20+, first scoring method (touchdown/field goal/safety), highest-scoring quarter, and period/half derivatives including first-half spreads and first-quarter totals.
Novelty and Special Props
For tentpole events — Super Bowl, NBA Finals, March Madness, World Cup — BetMGM expands into novelty territory. Coin toss result, Gatorade color, national anthem duration, and similar non-athletic outcomes. BetMGM also posts deep futures markets year-round: Player Next Team, First Coach Fired, award winners, and season-long statistical milestones. This futures depth is a BetMGM strength relative to smaller competitors.
BetMGM’s Key Prop Features
One Game Parlay
BetMGM’s One Game Parlay is the platform’s core prop combination tool. It lets you combine multiple outcomes from a single contest on one ticket — spread, total, player props, team props, and game props all mixed on one bet.
The Parlay Builder supports over 400 bet types with custom odds generated dynamically as you add legs. As each selection is added, BetMGM’s pricing engine recalculates the combined odds accounting for correlation between legs. If you bet the Chiefs to win AND Travis Kelce over 75.5 receiving yards, those outcomes are positively correlated, and BetMGM’s adjustment reduces your payout accordingly.
BetMGM’s One Game Parlay offers more granular control than some competitors. The 400+ bet type pool means you can often find niche combinations — a defensive player sack prop combined with a team turnover prop combined with a first-quarter total — that other books don’t allow within their same-game parlay builders.
Edit My Bet
Edit My Bet is BetMGM’s flagship feature and the single biggest differentiator in its product lineup. Once you’ve placed a parlay, Edit My Bet lets you modify the ticket while games are in progress:
Increase your stake — If your parlay is looking strong through the early legs, you can add money to the position mid-game.
Swap selections — Change a pick within the parlay. Built a Monday Night Football parlay but need to swap a player prop after seeing the inactive list 90 minutes before kickoff? Edit My Bet handles it.
Add legs — Tack on an additional selection to an existing parlay. Add a halftime NBA money line to your in-progress SGP.
Remove legs — The most valuable function. If one leg of your parlay is clearly losing, you can surgically remove it rather than watching the entire ticket die. BetMGM recalculates the odds and adjusts the payout accordingly.
No other major US sportsbook offers this level of live parlay modification. DraftKings requires you to delete and rebuild an entire SGP if you want to change one leg. FanDuel’s cash-out feature lets you settle early but doesn’t allow structural edits. Edit My Bet gives BetMGM a genuine product advantage for parlay-heavy bettors.
Lion’s Boost
Lion’s Boost is BetMGM’s signature odds enhancement program. Daily, BetMGM selects specific bets or pre-built parlays and boosts the odds — sometimes significantly.
Lion’s Boosts typically spotlight major matchups: NFL Sundays, NBA playoff games, Premier League headliners, MLB postseason. The boosted odds represent a reduced margin for BetMGM, and in many cases the boosted line offers genuine positive expected value. Sharp bettors routinely monitor Lion’s Boosts as part of their daily edge-finding workflow.
The catch: Lion’s Boosts carry maximum bet limits (often $25–$50 per boost), preventing bettors from exploiting the reduced margin at scale. But for recreational and moderate-stakes bettors, consistently hitting +EV Lion’s Boosts is one of the simplest profitable strategies in legal US sports betting.
Easy Parlay
Easy Parlay is BetMGM’s guided parlay builder for bettors who want curated combinations rather than building from scratch. BetMGM’s algorithms suggest pre-built parlays based on popular picks, trending selections, and featured events. Each Easy Parlay shows the combined odds upfront and can be placed with a single tap.
Easy Parlays often come with boosted odds, blending the Lion’s Boost concept with the convenience of not having to construct a multi-leg ticket manually. For recreational bettors, Easy Parlay lowers the friction of same-game and cross-sport parlay construction.
Live Betting and In-Game Props
BetMGM offers live props across all major sports, with odds updating dynamically based on game state. Live SGP creation is supported — you can build a One Game Parlay during a live game with adjusted lines reflecting what’s already happened.
BetMGM’s live betting interface is smooth but the vig on live props is noticeably wider than pre-game. This is consistent across the industry — the speed of live markets and the risk of delayed information force sportsbooks to build in extra margin. BetMGM’s live vig escalation is more pronounced than FanDuel’s, particularly on non-50/50 outcomes.
Props by Sport on BetMGM
NFL Props
BetMGM’s most popular and deepest prop market, with comprehensive coverage across every game on the schedule.
Quarterback props: Passing yards, passing TDs, completions, interceptions, rushing yards, longest completion, passer rating brackets.
Skill position props: Rushing yards, receiving yards, receptions, anytime TD scorer, first TD scorer, last TD scorer, longest reception, longest rush, carries, targets.
Defensive props: Sacks, interceptions, forced fumbles, defensive/special teams TD.
Kicking props: Total field goals made, longest field goal, total PATs.
Game/team props: Total points per team, first team to score, total touchdowns, first scoring method, overtime (yes/no), highest-scoring quarter, total punts, total penalty yards.
BetMGM’s NFL prop volume peaks for primetime games and expands dramatically for the Super Bowl. The Edit My Bet feature is particularly valuable for NFL parlays — with 90-minute windows between inactive announcements and kickoff, the ability to swap legs in response to lineup news is a genuine strategic advantage.
NBA Props
BetMGM’s second-deepest prop market, driven by the star-centric nature of basketball and high nightly game volume.
Standard props: Points, rebounds, assists, 3-pointers made, steals, blocks, turnovers, free throws made.
Combo props: Points + rebounds + assists (PRA), points + assists, points + rebounds. Combo props capture total statistical contribution in a single number and are uniquely popular for NBA SGPs.
Special props: Double-double (yes/no), triple-double (yes/no), first basket scorer.
BetMGM covers every regular-season NBA game with 100+ prop markets. Nationally televised games get expanded menus. NBA props drive significant One Game Parlay volume on BetMGM — the combination of high-scoring games, multiple stat categories, and star player concentration makes NBA the ideal sport for same-game prop combinations.
MLB Props
BetMGM splits MLB props between pitchers and batters, with pitcher strikeout props being the most popular and most modelable market.
Pitcher props: Strikeouts (the flagship MLB prop), earned runs allowed, hits allowed, innings pitched, outs recorded, first inning run (yes/no).
Batter props: Hits, home runs (yes/no), RBIs, total bases, runs scored, stolen bases, walks.
Game props: First team to score, run in the first inning (yes/no), total runs by team, extra innings (yes/no).
MLB player props must go 9 innings (8.5 if the home team is ahead) for action on BetMGM, or the outcome must already be determined. Batter props carry high single-game variance — 3-4 plate appearances make individual outcomes volatile. Pitcher strikeout props offer the best modeling surface because the sample per game is larger.
NHL Props
BetMGM’s NHL prop menu has expanded significantly, though it remains smaller than the Big Three US sports.
Player props: Goals (anytime/first goal scorer), assists, points, shots on goal, blocked shots.
Goalie props: Saves, goals against.
Game props: Total goals by team, first team to score, overtime (yes/no), period scoring props.
NHL prop betting carries lower volume than NFL/NBA/MLB on BetMGM, which means lines can carry more inefficiency. Fewer sharp bettors focus on NHL props, creating potential pricing opportunities for specialists.
Soccer Props
BetMGM covers the Premier League, Champions League, La Liga, Serie A, Bundesliga, Ligue 1, MLS, and international tournaments. With the 2026 FIFA World Cup approaching (June 11 kickoff, hosted in the US, Canada, and Mexico), expect BetMGM to massively expand its soccer prop menu.
Player props: Goals (anytime/first/last scorer), assists, shots on target, shots taken, cards (yellow/red).
Team props: Total goals by team, first team to score, clean sheet (yes/no).
Game props: Total goals, both teams to score (yes/no), total corners, total cards, halftime result.
Golf Props
BetMGM offers deep golf coverage across PGA Tour, Masters, and major championship events.
Tournament props: Outright winner, top 5/10/20 finish, to miss the cut, head-to-head matchups (72-hole and per-round).
Round props: Player round score over/under, birdies in a round, bogey-free round (yes/no).
BetMGM’s golf futures menu — including long-range tournament outrights and season award markets — is among the deepest in the industry.
Other Sports
BetMGM covers tennis (ATP, WTA — total sets, total games, aces, match winner), UFC/MMA (method of victory, round of finish, total rounds, fight to go the distance), college football and basketball (with state-specific restrictions on player props), and niche offerings including motorsports, darts, and cricket.
BetMGM Vig Analysis
Vig — the sportsbook’s built-in margin — is where BetMGM’s pricing shows a consistent pattern: competitive on coin-flip markets, escalating on lopsided lines.
Main Market Lines
BetMGM’s NFL and NBA spreads and totals are typically posted at -110/-110, equating to a 20-cent line and approximately 4.5% vig. This is industry-standard and competitive with DraftKings, FanDuel, and Caesars.
Player Props
On balanced player prop markets, BetMGM posts standard -110/-110 lines — the same 20-cent vig you’ll find at DraftKings and FanDuel. The divergence happens when lines move away from 50/50.
BetMGM consistently offers less favorable prices on the underdog side of lopsided prop lines. A market priced -200/+160 on FanDuel might sit at -200/+150 on BetMGM. That 10-cent difference on the plus-money side is a systematic pattern, not an occasional occurrence. It extends across props and into live betting, meaning bettors taking the less likely outcome consistently get worse prices at BetMGM than at FanDuel.
For over/under player props near the center line, BetMGM’s pricing is indistinguishable from the competition. The gap only appears — and grows — as the probability distribution becomes lopsided.
Same Game Parlays / One Game Parlays
Parlay vig compounds with each leg. Each selection carries its own margin, the correlation adjustment adds additional house edge, and BetMGM’s One Game Parlay pricing follows the industry pattern of approximately 16%+ hold on parlays versus 4.5% on straight bets. The opacity of correlation pricing means the actual house edge on SGPs is difficult to calculate precisely but consistently exceeds straight bet margins by a wide margin.
Vig Comparison Context
| Market | BetMGM | DraftKings | FanDuel | Pinnacle |
|---|---|---|---|---|
| Main spread/total | ~20 cents | ~20 cents | ~20 cents | ~5 cents |
| Player props (balanced) | ~20 cents | ~20-25 cents | ~16-20 cents | ~5-8 cents |
| Player props (lopsided) | ~30-40 cents | ~25-30 cents | ~20-28 cents | ~8-12 cents |
| SGP/OGP | ~16%+ hold | ~16%+ hold | ~15%+ hold | N/A |
| Live props | ~30-50 cents | ~25-40 cents | ~20-35 cents | ~10-15 cents |
The AgentBets Vig Index tracks live overround across sportsbooks including BetMGM. Agents that route bets to the lowest-vig book on each individual market can capture pure execution alpha — getting the same position at a better price.
Betting Limits and Account Restrictions
BetMGM’s house rules state a minimum wager of $0.50 and a maximum of $10,000,000. In practice, BetMGM determines maximum wager amounts per patron on all events, including propositions and futures. The posted maximum is a theoretical ceiling; your actual limit depends on your account history and the specific market.
BetMGM limits winning bettors consistent with industry practice. If you consistently profit on props, beat closing lines, or display sharp betting patterns, BetMGM will reduce your maximum stake. This is identical to the policy at DraftKings, FanDuel, Caesars, and every other regulated US sportsbook.
For player props specifically, BetMGM voids straight bets on players who don’t play. If a player is ruled out on the injury report before the game, BetMGM removes all player prop markets for that individual.
Winner treatment summary: BetMGM is neither the most aggressive limiter (DraftKings holds that distinction) nor the most tolerant. Casual and moderate bettors will never encounter limits. Professional-level prop bettors should expect eventual restrictions and plan their account management accordingly.
Maximum payout rule: BetMGM’s house rules state that maximum payout limits can only be established through limiting the amount wagered — they cannot retroactively reduce a winning wager’s payout after the bet is placed.

Agent Strategy for BetMGM Props
An autonomous prop betting agent uses BetMGM data within the Agent Betting Stack:
Three-book triangulation: Ingest prop lines from BetMGM, DraftKings, and FanDuel simultaneously. BetMGM’s systematic vig escalation on lopsided lines means it’s often the worst price on plus-money props — but it also means BetMGM occasionally misposts the favored side at a better price than competitors when its models disagree with the consensus.
Lopsided line exploitation: Because BetMGM’s vig pattern is predictable (tight on balanced markets, wide on lopsided ones), an agent can focus on markets where BetMGM’s line diverges from FanDuel or DraftKings on the balanced side. When all three books post similar lines on a prop but BetMGM offers a better price on one side, the implication is that BetMGM’s model assigns different probabilities — and the difference is edge, not vig.
Lion’s Boost arbitrage detection: An agent can automatically compare Lion’s Boost odds against sharp market prices to identify +EV boosts. Many Lion’s Boosts offer genuine positive expected value at their maximum stake. Systematically capturing these micro-edges across daily boosts compounds over time.
Cross-book execution: Use BetMGM for price discovery and line comparison, but route execution to whichever book offers the best price on each specific market. The AgentBets Vig Index provides real-time vig comparison to automate this routing.
BetMGM vs. the Competition

|---|---|---|---|---|
| US Market Share (GGR) | ~13% | ~34% | ~44% | ~5% |
| States Available | 23 + DC + PR | 26 + DC | 24 + DC | 20+ |

| Odds Boosts (Props) | Lion’s Boost (daily) | Profit Boost | Odds Boost | Daily boosts |
| Prop Vig (Balanced) | ~20 cents | ~20-25 cents | ~16-20 cents | ~20-25 cents |
| Prop Vig (Lopsided) | ~30-40 cents | ~25-30 cents | ~20-28 cents | ~30-40 cents |

| Live Prop Betting | Yes | Yes | Yes | Yes |
| 2025 Revenue | $2.8B | $6.1B | ~$6.4B (est.) | ~$1.5B (est.) |
BetMGM’s competitive position is clear: it’s not the deepest prop menu (DraftKings), not the tightest vig (FanDuel), but it offers the best parlay management tools (Edit My Bet), the strongest physical-world loyalty program (MGM Rewards), and consistent Lion’s Boost promotions that provide genuine +EV opportunities.
State Availability and Restrictions
BetMGM is live in 23 states plus Washington D.C. and Puerto Rico as of March 2026. Key regulatory notes:
College sports restrictions: Several states prohibit or restrict player prop betting on college sports. In states like New York, Massachusetts, and others, BetMGM will not offer player props on college football or basketball games. Game props and team totals may still be available depending on the jurisdiction.
State-specific feature availability: Not all BetMGM features are available in every state. Some states restrict same-game parlays, live betting, or specific prop categories based on local regulations. Always check BetMGM’s state-specific terms.
Geo-fencing: BetMGM requires physical presence within a legal state to place bets. The app uses GPS verification. You can create an account from anywhere but must be within state borders to wager.
Puerto Rico access: BetMGM is one of the few major US sportsbooks available in Puerto Rico, providing access to bettors on the island.
The Bottom Line
BetMGM occupies a clear third position in the US sportsbook hierarchy — not the most innovative, not the cheapest, but the most structurally integrated with physical-world gambling infrastructure. The MGM Resorts backing gives BetMGM advantages that pure-play digital competitors cannot replicate: a 30+ property loyalty network, the brand equity of the most famous casino brand in the world, and the operational expertise of a company that has been taking bets since long before PASPA fell.
For prop bettors specifically, BetMGM’s value comes from Edit My Bet (unmatched in the industry), consistent Lion’s Boost promotions (frequent +EV opportunities), and solid prop depth across all major sports. The vig penalty on lopsided lines is the primary drawback — if you frequently bet plus-money props, FanDuel will consistently offer better prices.
For agents, BetMGM serves as a critical third data source for cross-book comparison. The systematic vig pattern (competitive on balanced, wide on lopsided) creates a predictable pricing fingerprint that agents can exploit when BetMGM’s model disagrees with the consensus. And the betmgm key on The Odds API makes integration straightforward.
