@camusafk @PredMTrader @judyshel @rigatohni Yeah unfortunately poly mentions are much less volume usually. And the new fees probably wont help too much. Kalshi has done great embracing the category and obviously the graph shows its working

Mentions on Kalshi did $179 million total volume in February 2026. The rate of growth is parabolic multiplying nearly 50x in just 6 months. At this rate we are on pace to do more monthly volume than the entire stock market by Q3 2027...

@douglas_sh_base @PredMTrader @judyshel @rigatohni 180 million x50 every 6 months for next 18 months is 22.5 trillion in monthly volume. If we changed the nfl to having multiple superbowls a year it could maybe even happen sooner too

Learned from @Foster on the GP/SP podcast that it’s pretty easy to see when recs are selling their shares out of pure fear

@anon629186391 @RookeBrollins @Kalshi Maybe not perfect but definitely the best out there right now. I know of just a handful of markets i've been in recently where they've paid multiple 6 figures to pay both sides 🤷‍♂️

Of all the Poly announcements today, this one makes me feel the best. If you're gonna trade a platform, you should trust that the platform will take responsibility when an issue on their end causes losses to users. For those who weren't aware, a few months ago @RookeBrollins lost ~50k due to a UI bug on Poly, and is now getting a refund. Kalshi has been great in this regard in my experience, often refunding losses that are their fault from bugs, outages, and poor rules. Sweet to see the same happening on poly nowadays :)

Update: While I have been largely silent about this on X so far, I can now announce that @Polymarket has agreed to fully refund the loss caused by the glitch, not in small part thanks to the patient work of @chrund1e, @kea1on and Candiey, really underappreciated team (1/3)

@DrSlipz @PredMTrader Yeah, a good chunk is catching mistakes, some are good longshots that paid off (like time POTY). I'm not some super predictor calling 1% picks weekly

Super fun time chatting on here with @goldenpants013 and @Sports__Proj - We talked about a ton, even talked about way back when I was doing chores to play Full Tilt Poker tourneys when I was like 10/11 lol Give it a listen😁
GoldenPants13@goldenpants013

New Episode of the POD out today. Myself and @Sports__Proj interview @Foster - one of the most successful non-sports traders on Kalshi & Poly. Some great stuff in here including a middle on the "Best AI" market, non-sports RFQs and why Foster is willing to buy anything for 1c⬇️
