The Potomac Summer Poker Open will bring more than two weeks of tournament poker to MGM National Harbor this August, with PokerNews reporting that the series is powered by BetMGM Poker and will run from August 5 through August 17, 2026. The 13-day festival carries an overall guarantee of more than $1.5 million spread across 23 events, giving the Washington, D.C. area a substantial live poker destination during the heart of the summer tournament season.
Schedule and Guarantees at MGM National Harbor
MGM National Harbor, located just outside the nation’s capital on the Maryland side of the Potomac River, will host the full slate of events inside its poker room over the two-week window. Organizers have built a schedule around 23 tournaments carrying a combined guarantee north of $1.5 million, a structure designed to give players of different bankrolls multiple ways to enter the series. The lineup mixes lower buy-in volume events with higher buy-in showcase tournaments, a format that has become standard for regional series looking to draw both recreational and grinding players over a sustained stretch.
Because the series spans nearly two full weeks, players traveling from outside the region have room to plan around specific events rather than a single weekend, one reason multi-flight series have grown popular across the industry.
Main Event Structure: $750,000 Guaranteed
The headline attraction of the Potomac Summer Poker Open is its Main Event, a $3,000 buy-in tournament carrying a $750,000 guarantee. The tournament will use a two-flight starting structure, with players able to enter on either August 14 or August 15. Survivors from both flights will combine for Day 2 on August 16, and the field will play down to a champion at the final table on August 17.
That four-day arc, two starting flights followed by a combined Day 2 and a decisive final table, mirrors the structure used at many of the largest events on the calendar, including the multi-flight format popularized by the World Series of Poker. Readers newer to tournament poker who want a refresher on how starting flights and final table play work can find a breakdown in Poker Pro Academy’s WSOP guidewhich covers the mechanics behind large-field tournament structures like the one the Main Event will use. A $3,000 buy-in against a $750,000 guarantee suggests organizers expect a healthy turnout from both local grinders and traveling professionals, given the venue’s proximity to a major metropolitan population center.
Robert Anderson Returns to Defend His Title
Robert Anderson enters this year’s series as the defending Main Event champion, having won last year’s edition out of a field of 377 entries. That turnout produced a prize pool of $1,017,900, and Anderson’s victory was worth $211,915 in first-place money. Defending champions returning to a series carry a natural storyline, and Anderson’s title defense will be one of the threads PokerNews and other outlets are expected to follow as the 2026 Main Event field takes shape across its two starting days.
Should this year’s field approach or exceed the 377 entries from 2025, the $750,000 guarantee would likely be exceeded, pushing the eventual prize pool and first-place payout above last year’s marks. Guarantees are a floor, not a ceiling, and prize pools routinely outstrip the advertised number when a Main Event draws a strong field.
NLH Opener, Monumental Stack, and Mixed-Game Events
The Main Event is far from the only tournament on the schedule. The NLH Opener carries a $600 buy-in and a $500,000 guarantee, and it will run across seven separate starting flights, making it the most accessible high-guarantee event of the series for players who want a lower buy-in with a shot at a large field-driven prize pool. The Monumental Stack follows a similar model at a $500 buy-in with a $100,000 guarantee spread across six starting flights.
Beyond those two multi-flight events, the schedule includes a rotation of mixed-game tournaments for players looking for variety beyond no-limit hold’em. Events are planned in TORSE, pot-limit Omaha, 8-Game Mix, and Big O, giving mixed-game specialists a reason to travel even if they skip the larger no-limit fields. The series also includes bounty tournaments, which reward players for eliminating opponents in addition to the standard payout structure, along with a run of satellites that let players win their way into bigger buy-in events, including the Main Event, for a fraction of the direct cost. Players unfamiliar with how bounty formats or satellites change basic strategy may want to review the fundamentals in Poker Pro Academy’s how to play poker guide before trying an unfamiliar game type.
BetMGM Poker’s Role and What Players Should Know
The series is powered by BetMGM Poker, which continues to expand its footprint in live tournament poker by attaching its brand to regional series like this one. BetMGM Poker has a new-player promotion tied to the platform that includes a 100% deposit match up to $1,000, along with up to $75 in tournament tickets for new sign-ups. As with any online poker promotion, the offer is informational rather than a guarantee of any outcome, and players should treat it as they would any deposit bonus: read the terms, understand any wagering requirements, and only play with money they can afford to lose. Poker is an entertainment product with real financial risk, and players should be at least 21 and located in a jurisdiction where BetMGM Poker operates legally before engaging with the platform.
What the Series Means for the Summer Festival Calendar
The Potomac Summer Poker Open lands in a part of the calendar when the live poker community’s attention is often split between multiple regional series happening in parallel. A 13-day run with a $1.5 million-plus overall guarantee and a $750,000 Main Event gives MGM National Harbor a series substantial enough to draw attention on its own, without needing to compete directly with the largest series on the national calendar.
PokerNews has indicated it will provide live reporting throughout the series, beginning with Day 2 coverage of the preliminary events and continuing through the Main Event final table on August 17. That kind of sustained coverage typically means chip counts, hand histories, and player interviews will be available as the series progresses, giving fans who cannot attend in person a way to follow the action through to whoever succeeds Robert Anderson as Main Event champion.
For players considering a trip to MGM National Harbor this August, the schedule’s mix of accessible buy-ins, mixed-game variety, and a marquee Main Event gives the Potomac Summer Poker Open a shape similar to other successful regional series: something for the grinder chasing a multi-flight guarantee, and something for the serious player targeting the $750,000 Main Event.
