A bettor who goes by the X username FoaznPoker has gone viral for losing $50,000 after Jannik Sinner‘s upset loss in the French Open.

Italy’s Sinner was on a months-long, 30-match winning streak going into the tournament against 56th-ranked Juan Manuel Cerundolo of Argentina. The Athletic reports he was -300 to win the French Open before the start of the tournament, which would have marked a rare 1-to-3 payout.

However, Sinner lost in the second round against Cerundolo, having received medical attention between the third and fourth sets, likely do to the 90-degree Fahrenheit heat.

Through the sports betting site Kalshi, user FoaznPoker bet $50,000 with 98 percent odds for a max payout of $50,949.07 — a profit of approximately $950 — on Sinner’s win. The user also bet another $5,000 on a separate betting site for a potential max profit of $50.

Foazn posted screenshots of his bet to X on Wednesday night, with the caption: “If you saw $999.07 on the ground, you’d pick it up, right? Jannik Sinner,” followed by the lock and key emoji and, “Couple things: Sinner is GUARANTEED to win, Foazn won’t wake up at 5am to watch. I make money in my sleep; you wake up to make money #levels.”

The user has since made a series of X posts about the massive loss, writing, “Kind of annoyed I wasn’t $999.07 richer when I woke up and instead will be 10 minutes after. Life of a grinder I suppose,” followed by, “If you could burn $55,000 under the Roland Garros heat, you’d do it, right? Ruined all my hard work on Kalshi and FD this year. Tough.”

Foazn added, “In the last 3 days I’ve made -$53,569.73 by picking up money off of the ground. That works out to -$6,517,650.48/year. Why aren’t more people doing this?”

The internet has erupted with reactions to the bettor’s now-viral X post, with big names like Darren Rovell and Jimmy Kimmel‘s cousin, who goes by Cousin Sal, getting in on the action:
