ACR Poker opened its Online Super Series on Sunday 8 November 2026 with the same $20 million guarantee it carried in May and a different set of Main Events underneath it, according to the schedule the room published for the 8 to 24 November run.
The $215 Main Event guarantee falls from $1 million to $750,000, the $66 doubles to $500,000, and the two biggest hold at $1.5 million each. The published schedule lists 143 events, down from 171 in May, split into a Day Series and an Evening Series with separate leaderboards.
The four Main Events still carry $4.25 million between them. The money has come off the buy-in that only just covered its guarantee in May and gone onto the cheapest Main Event, which is now asked to find twice the field.
How the ACR OSS November 2026 Main Event Guarantees Moved
Four Main Events, four buy-ins, and two of the four guarantees changed. ACR's release gives the $4.25 million total; the per-event figures below are the ones on the schedule itself.
| Buy-in | November 2026 guarantee | May 2026 guarantee | Change |
|---|---|---|---|
| $2,650 | $1,500,000 | $1,500,000 | Held |
| $1,050 | $1,500,000 | $1,500,000 | Held |
| $215 | $750,000 | $1,000,000 | Down $250,000 |
| $66 | $500,000 | $250,000 (single day) | Doubled, now multi-flight |
VIP-Grinders is an ACR Poker affiliate partner. The top two guarantees are unchanged from May, when the $2,650 and $1,050 events each carried $1.5 million.
Why did the $215 Main Event guarantee drop?
The May edition's $215 Main Event is the likely reason. According to results reported after that series, it drew 4,844 entries and finished with its prize pool sitting on the $1 million guarantee rather than above it.
Nobody at ACR has said the two are connected, and the room's releases carry no May wrap-up. The schedule is the only statement: the same buy-in now carries a quarter less.
What Each Guarantee Needs to Fill
A guarantee only matters against the field it needs. Using ACR's usual split, where $2,650 puts $2,500 into the pool and $66 puts $60 in, each Main Event has a break-even number of entries.
These figures are VIP-Grinders arithmetic, not ACR's, and they assume the standard buy-in split. The $2,650 Main Event needs 600 entries to cover $1.5 million and the $1,050 needs 1,500. The $215 needs 3,750 to cover $750,000, and the $66 needs 8,334 to cover $500,000.
Set those against May. The 4,844 entries the $215 drew then would clear its new break-even by more than a thousand, so the cut gives the event headroom it did not have at $1 million.
Which OSS Main Event is most likely to overlay?
The $66. In May it was a single-day event with a $250,000 guarantee, and reported results put its final pool at $252,000, which on the same split is about 4,200 entries. Doubling the guarantee asks for roughly twice that field, spread over five flights instead of one.
If the flights on 8 and 15 November come in light, the 22 November flight is where the value sits. Players who bag more than once can combine stacks for Day 2, which keeps entries flowing into the later flights.
How the Day Series Differs From the Evening Series
The format change is the two-track schedule. Events are tagged to one of two tracks by start time, each with its own leaderboard, and ACR says the two leaderboards together carry more than $77,000 in added cash and tournament tickets.
- The Day Series has 77 events with earlier Eastern Time starts, aimed at European players.
- The Evening Series has 66 events with later Eastern Time starts, aimed at US players.
- Some Evening Series events are flagged for a separate weekly leaderboard for US players.
- Players can score on both leaderboards in the same series.
May's leaderboard contest paid $30,500 across High and Low divisions. The November boards carry more than double that while the schedule has shrunk.
What do the Day and Evening leaderboards pay?
The published prizes put $7,500 plus a January Venom ticket at the top of the Day Series board. The Evening Series winner gets $5,000 plus a January Venom ticket.
ACR's own release gives only the combined total. Treat the split as the schedule's figure rather than the room's statement.
The Three Sundays That Decide the Series
Every Main Event flight but one lands on a Sunday, and the Day 2s follow on 22 and 23 November. The $66 opened with two flights on 8 November; the three bigger events start on 15 November.
| Event | Day 1 flights | Day 2 |
|---|---|---|
| $2,650 Main Event | 15 and 22 November | Monday 23 November, 1:30 pm ET |
| $1,050 Main Event | 15 and 22 November | Monday 23 November, 1:30 pm ET |
| $215 Main Event | 15 and 22 November, turbo flight 23 November | Monday 23 November, 1:30 pm ET |
| $66 Main Event (turbo) | Two on 8 November, two on 15 November, one on 22 November | Sunday 22 November, 1:05 pm ET |
Stacks from more than one qualifying flight combine for Day 2 in all four events. The $215 also gets a turbo flight on 23 November, the day of its Day 2, a late route in for anyone who missed both Sundays.
The series ends on 24 November, the day after the three big Main Events play their Day 2s. That leaves a Tuesday of closing events once the biggest pools are settled.
Moneymaker Mystery PKO Plays Its Day 2 on 22 November
The one named event on the schedule belongs to ACR Pro and 2003 champion Chris Moneymaker. The $109 Moneymaker Mystery PKO carries a $1 million guarantee and a $100,000 top mystery bounty, with Day 1 flights running since 1 November.
Day 2 is on Sunday 22 November, the same day as the $66 Main Event's Day 2. Qualifying stacks from multiple flights combine, as they do across the Main Events.
The Moneymaker name has carried a $109, $1 million guaranteed mystery event on ACR since the Mystery Million debuted in November 2025 and returned in February 2026. The November 2026 version runs as a Mystery PKO, with its Day 2 inside the OSS.
What Comes Next for the Series
ACR published running totals during the March and September editions, and the first for November will show whether the two opening $66 flights put the doubled guarantee on track. The 15 November flights are the first real test of the $215 at its new level.
The results from 22 and 23 November will settle the question this edition poses: whether moving $250,000 from one Main Event to another was a read on the field or a bet against it. The May edition of the Online Super Series is the comparison to keep open.
