Real-time whale wallet tracking, cross-platform arbitrage, new-market alerts, daily research and a private desk of serious traders. Every tool, one membership, and the first 30 days cost nothing.
If you trade Polymarket or Kalshi with any regularity, at least two of these are you.
By the time a market shows up on your feed, the wallets that matter are already positioned. You're buying their exit.
A tracker here, a Discord there, a news feed you refresh by hand. Nothing connected, nothing ranked, nothing that pings you.
Polymarket and Kalshi disagree on the same outcome more often than you'd think. That gap goes to whoever sees it first. You're not looking.
Without a journal and peer review, every trade is a one-off. You can't compound what you never measured.
I didn't start Probability Lab to sell a Discord.
I started it because I was trading Polymarket and Kalshi off gut feel and five open tabs, and I knew the wallets on the other side of my trades had better information than I did. So I built the tools I wanted to exist: wallet tracking that actually shows who's positioning, alerts that reach me before the crowd, a scanner that watches both platforms for price gaps while I sleep. Then I put them in one place, with the traders I'd actually want to compare notes with.
The first 30 days are free because a month inside is a better pitch than anything I could write on this page.
Not a roadmap. Everything below is running today, and new tools ship to every member at no extra cost.
See which wallets are winning and what they're buying right now. Follow the ones with real track records, get pinged when they move, mirror the trades you'd never have found on your own.
New markets are mispriced most in their first hours. Get notified the moment one lists on Polymarket or Kalshi, before liquidity and attention pile in.
Curated market-moving news, filtered down to what actually changes a probability, so you stop refreshing feeds and start acting on them.
Finds markets that are effectively decided but still trading below where they'll resolve. The low-drama setups most people scroll straight past.
Log every position, tag your reasoning, and see what's actually working on a performance calendar. The difference between a hobby and a process.
One briefing a day on what moved, why it moved, and which markets it touches next. Three minutes to read instead of an hour to scroll.
The same market is often priced differently on Polymarket and Kalshi at the same time. Arbitrage Finder scans both platforms continuously and surfaces those gaps the moment they appear, ranked by spread size, so the biggest opportunity is always at the top.
Daily research, a full course, a searchable reference library and a private community of people trading the same markets you are.
Trade ideas posted with the reasoning attached, so you can judge the logic before you copy the position.
Structured video training from first market to full process. Expected value, sizing, risk, selection.
A searchable written reference for the moment a rule, a resolution source or a term stops you mid-trade.
anyone else see the 6¢ gap on the shutdown market? kalshi still hasn't caught up
yeah, but check the resolution wording. they don't count a CR as avoiding it
good catch. that's why the gap exists. sizing it small.
A small community of people who trade these markets seriously. Post an idea, get it pressure-tested before you size it.
Every month we pick the single best call from the community alpha channel. The winner gets $100 and a free month. No points, no grinding. The best thinking wins.
This is what a serious month inside looks like. By the end of it you'll know whether it pays for itself. That's the point of the trial.
We'd rather you skip the trial than take it and never open the tools.
That's what comparable tools, research services and training cost on their own. You get all of it for one price, and the first month for none.
Same markets. Same capital at risk. The only variable is your inputs.
Start the trial. Use every tool, read every call, sit in the desk for a full month. If it isn't for you, cancel in two clicks any time before day 30 and you're never charged. No forms, no retention call, no "are you sure" loop. We'd rather earn the second month than trap you in the first.
From people trading the same markets you are.
One membership, nothing held back. Start today, decide on day 30 with a month of your own results in front of you.
The markets don't wait for you to get organised. The trial costs nothing, the price lock ends when the next tool ships, and both of those are true today.
$0 today. Then $99/mo, locked in. Cancel any time before day 30 and pay nothing.
