MULTI-MILLION DOLLAR RINSE: Full single-post summary for people with normal sleep schedules of the most insane rinsing of bond bots I've seen firsthand, in which PM bonders appear to have lost 7 figures🤯 Scene: Last MLB game of the night (Giants vs Angels) bottom of the 10th inning tied 6-6. The time is ~1:15am EDT - With the bases loaded, Devers hits what is normally a ground rule double. The initial final score shown is an 8-6 Giants win (due to an official MLB scorer error). Video below in thread - Over 13.5 runs, Giants -1.5, and Giants team total o7.5 runs bond to 99c thanks to bots - MLB rules state that a walk off ground rule double cannot score multiple runs and in this scenario counts as a single instead of a double - People start to realize this and insane action comes in to unbond the above markets. Prices go absolutely haywire, touching 1c and 99c multiple times - Kalshi closes and settles the totals & team totals markets while at least one (if not all) of the listed source agencies (MLB / Fox Sports / ESPN) still showed the final score as 8-6. PolyUS does the same for settlement of Giants -1.5 - However, the Kalshi spread (run line) markets remained open longer. Source agencies had then changed the final score to be 7-6. Market volume on the spread balloons from under 12,000 to 5 million (!) between the start of the bottom of the 10th inning and final market settlement - Despite Kalshi settling the total as over 13.5 based on an 8-6 final score, per their CFTC rules, the spread must now settle Angels +1.5 as a win, and it does - PolyInt settles Angels +1.5 as a win as well, rinsing botters there too and appearing to make the total losses for traders assuming a 8-6 final score "multi-millions" across all exchanges - Sportsbooks all appear to have paid out incorrectly initially as well, but it seems all of them have resettled based on the 7-6 final score. CFTC certified exchanges on the other hand don't quite work the same way as sportsbooks. - I fail to make riches since my 1am brain was staring at just the totals market and didn't notice the spread market had stayed open longer until it was too late - I'm aware of some of the big winners, but am yet to hear who specifically were the big losers on this score adjustment - Kalshi volume on the two "incorrectly" settled markets: 1.1mil on o/u 13.5 runs, ~60k on o/u 7.5 Giants team total. No idea or guess on how much was traded on the PolyUS "incorrectly" settled spread market. I would not expect a refund if you had the wrong side of these markets since the settlements appear to have complied with the sites' CFTC rules, but we'll see TLDR: An official MLB score correction post-game made some grinders rich and rinsed others (mostly botters, I assume). Per the sites' CFTC rules, it appears all markets were settled correctly despite being inconsistent settlements
