The Winning Poker Network’s flagship series will run on ACR Poker, PokerKing, and BlackChip Poker from March 1st to 23rd, 2026. The schedule features over 750 tournaments, including multiflighted events and different Omaha tournaments — we’ve compiled all the key information in this article.

Details of 2026 Spring OSS XL

  • 754 tournaments with a $50,000,000 guarantee
  • 39 tournaments of 5 Omaha variants with a focus on 5C PLO8
  • 5 Mystery Bounty tournaments
  • 4 Main Events
  • 1 newest special tournament named after Phil Nagy
  • Buy-ins from $0.55 to $10,300
  • Guarantees from $250 to $2,000,000

Stud Is Gone but Omaha Is Full-Packed

For some unknown reason, in the spring of 2026, ACR Poker decided to remove 7 Card Stud tournaments from the OSS XL schedule and expand the Omaha tournament schedule, with a particular focus on PLO5.

We’ve grouped all of these tournaments into tables by date to make it easier for you to navigate.
