Hey 👋 Dave here, solo founder of Tickerbook.
This started a few months ago when I noticed the same contract "Fed cuts at the May FOMC "was trading at 0.35 on Polymarket and 0.41 on Kalshi. Same event, same day, 6 cents apart. Looked again the next morning — still there, different number. Looked again the next week — structural.
Turns out this happens on hundreds of contracts. Kalshi is US-regulated, Polymarket is permissionless and global, and their user bases + fees + liquidity profiles mean prices diverge in ways that don't close themselves. Nobody was surfacing it in one place.
So I built Tickerbook. It reads both books as one:
→ Arbitrage scanner — cross-venue mispricings with net edge after fees
→ Dutching — multi-outcome events where the full basket costs less than $1
→ AI briefs — structured research on any contract (powered by Claude Sonnet 4.6)
Important: we're not a broker. No custody, no execution. You trade on the venues themselves. Tickerbook is a research tool — that's the whole product.
Launch pricing: $29/mo for the first 1,000 members, locked for life. Then it goes to $49. There's a free tier too.
Would genuinely love your feedback. What's missing? What's confusing? If you trade prediction markets, I want to hear it. 🙏
