Onyx High Roller Series 2026: Eibinger and Vyborov Take Top Prizes

From a record-breaking Pot-Limit Omaha field to a seven-figure comeback in the No-Limit Hold'em Grand Slam, the early stages of the series have already produced some of the most compelling narratives of the 2026 season.

The series made an immediate impact with Event #9, the $10,000 PLO Opener, which proved that the four-card format is rapidly becoming a favorite among the high-roller elite. Surpassing the earlier No-Limit Hold'em opener with ease, the tournament drew 232 entries, creating a massive $2,180,800 prize pool.

Russia’s Artur Vyborov emerged as the champion, though his path to the trophy was anything but easy. After an early exit, Vyborov re-entered with a slim 20-big-blind stack and picked his way through a final table featuring specialists like Laszlo Bujtas. In a dramatic heads-up showdown against Aren Bezhanyan, Vyborov overcame a dominant pre-flop hand by completing a flush on the river, tripling his career earnings and taking home $450,000.

If you need a lesson in never giving up, look no further than Matthias Eibinger’s run in the $50,000 NLH Grand Slam. Before the event, Eibinger described his experience in Cyprus as a "disaster," having fired four bullets in the $100k Championship and two on Day 1 of the Grand Slam without a single cash. His luck finally turned on his third and final bullet.

Eibinger showcased incredible discipline at the final table, famously folding more than 60 consecutive hands before striking at the perfect moment.
