News Three Huge OSS Main Events Headline This Sunday Americas Cardroom May 15, 2026 The $20 Million Online Super Series is already rolling, but this Sunday is when things really start to heat up. On May 17th, three of the biggest OSS events arrive, giving you a shot at massive guarantees across multiple buy-in levels. The action starts at 11:05am ET with three Day 1A flights: $2,650 buy-in Main Event – $1,500,000 GTD $1,050 buy-in Main Event – $1,500,000 GTD $215 buy-in Main Event – $1,000,000 GTD Each Main Event features two starting flights, with Day 1B scheduled for Sunday, May 24th. Players who advance from either flight will return for Day 2 on Monday, May 25th, when the race toward the final tables continues. And you don’t need to buy in directly to take your shot. There are plenty of affordable satellites running, giving players a chance to win their way into these big events without breaking the bank. Sunday’s three Main Events are the biggest immediate draw, but they’re just part of the story. The $1,000,000 GTD Main Multi-Flight is already underway, giving you more chances to build a stack before Day 2 on Monday, May 25th. The event has a $630 buy-in, with Day 1 flights continuing throughout the series. The Mystery Bounty schedule is packed, too. The $109 buy-in Mystery Bounty Multi-Flight comes with a $750,000 guarantee and returns for Day 2 on May 25th. Two more Mystery Bounty events are also in play, with a $150,000 GTD tournament at the $33 level and a $75,000 GTD event for just $5.50. Both wrap up on Sunday, May 24th. Don’t forget about the Leaderboard competitions, either. They’re already underway, with $30,500 in prizes up for grabs across the High and Low divisions. Every deep run can do more than boost your bankroll. It could also move you up the standings, and all Leaderboard prizes are fully funded out of our own pockets. Sunday is just one part of the bigger OSS push. The series runs through May 25th, with more than $20 million guaranteed across 171 events and buy-ins starting from just $5.50.
