ACR Poker Posts $5M in OSS XL Main Event Guarantees
Three tiered buy-in Main Events run simultaneously this Sunday under the OSS XL banner.
ACR Poker is running three simultaneous Main Events this weekend under its Online Super Series (OSS) XL banner, posting a combined $5 million in guaranteed prize money, according to Card Player.
Why It Matters
A $5 million guarantee spread across multiple buy-in tiers gives recreational and high-stakes players alike a concrete reason to log on this Sunday. Tiered Main Events reduce the winner-takes-all pressure of a single flight structure, broadening the addressable player pool and typically driving higher overall registration numbers. For ACR Poker — which operates under the Americas Cardroom brand — hitting or exceeding guarantees strengthens its reputation in a competitive online poker market where overlay risk is a persistent operator concern. Players should note that poker tournaments involve significant financial risk; a buy-in does not guarantee a return.
Context
The OSS XL is ACR Poker's expanded variant of its long-running Online Super Series, designed to compress high-volume tournament action into a concentrated weekend window. As of September 2026, ACR Poker remains one of the few major online poker rooms accessible to U.S. players, giving its series outsized relevance in a market starved of licensed competition. Three-tiered Main Event structures — typically spanning low, mid, and high buy-in brackets — have become a standard tactic among poker networks seeking to maximise field sizes without cannibalising entry fees.
What's Next
Registration windows for all three OSS XL Main Events are open this week; players should check ACR Poker's tournament lobby directly for exact buy-in amounts and late-registration deadlines. Final results and overlay figures will clarify whether the $5 million guarantee was met — a key data point for assessing the series' long-term viability.
