Tenki
Tenki is a prediction market AI research tool from Whimsey Labs for Kalshi and Polymarket: it scans thousands of markets across both platforms and flags opportunities where prices diverge from the evidence. Note: the old name AI Sports Picks for Kalshi Traders (NBA/NFL/NHL/NCAA) is outdated — the product has pivoted from pure sports picks to all-category research, and is currently in a Waitlist pre-launch phase, not yet live.
Core capabilities
- Continuous market scanning: monitors thousands of markets on both platforms 24 hours a day, narrowing down to the few opportunities worth a close look
- AI mispricing detection: compares market traded prices against evidence-backed fair probabilities, surfacing divergences for review
- 3–7 daily picks: a short list each morning with evidence, price gaps, and what would have to happen for the call to be wrong
- Verifiable reasoning trails: We show our work — every pick carries bull/bear arguments on both sides plus sources, rejecting black boxes
- Public track record pledge: every settled result will be published, losses included, bad days not deleted (fulfilled only after launch)
- One feed for two markets: side-by-side comparison across both platforms, covering the categories its models handle best (macro/Fed, for example)
Use cases Active traders who live on Kalshi/Polymarket but hold full-time jobs with no time to sweep the board, and data-driven regulars who want a second pair of eyes plus checkable homework; curious newcomers can learn from its mispricing logic. Not for high-frequency trading or anyone needing automatic order placement — it does research only, no orders, no API.
Unique strengths It bills itself as the Bloomberg of prediction markets: it runs no markets and places no trades, only narrow-and-deep research picks. Differentiation lies in verifiable evidence chains + time-aware LLM reasoning, advocating one source for both platforms, with a publish-losses-included transparency pledge ahead of most signal services.
Editorial verdict The concept and founding team (Michael Ulin, with a McKinsey/ZestyAI/Paxton background; related companies have raised $78M+ combined) are credible, but the product cannot be purchased yet and neither track record nor pricing can be verified, with the historical messaging having flip-flopped repeatedly. Overall 2.5/5: register for the Waitlist first, and evaluate paid tiers only after launch and publication of dated results.

FAQ
Is Tenki free?
No. There is no permanent free tier, only a promised free trial of about 2 weeks after launch; the current free Waitlist signup is an audience-building move and does not constitute a free product tier (is_free=false).
What can Tenki be used for?
It scans thousands of prediction markets on Kalshi/Polymarket and uses AI to find opportunities where traded prices diverge from the evidence, outputting 3–7 research picks daily with evidence chains and two-sided arguments. Research only — no order placement, no automated execution.
What is Tenki's relationship to the Japanese weather site tenki.jp?
None — pure name collision. tenki.jp is the largest weather media outlet run by the Japan Weather Association (a registered trademark); Tenki is Whimsey Labs' prediction-market AI tool. Distinguish them in searches and beware copycat sites.
Can I pay to use Tenki now?
Not yet. The site is in a Launching soon · Waitlist state, and its FAQ self-answers Not yet available; there is no pricing page (/pricing 404). The $10/$12 monthly figures in third-party listings are old historical figures — withdrawn and unreliable.
Is the claimed 76% accuracy / 59% win rate credible?
Not as evidence of real performance. All figures are self-reported by the vendor with no third-party audit, and they have been pulled from the site; it now only pledges to publish the full record (losses included) at launch. Wait for checkable, dated public results before judging.
How does Tenki differ from Kalshi/Polymarket's built-in AI?
Platform built-in AI (such as Kalshi's xAI Grok and Polymarket's institutional data) is free but confined to one platform; Tenki is a third-party paid research layer across both platforms, and its price premium must be backed by a credible track record — a promise not yet fulfilled.
Who is Tenki suitable for?
Active traders with full-time jobs who trade on Kalshi/Polymarket but lack time to sweep the board, and quant-leaning, data-driven newcomers. Not for high-frequency traders, those needing automatic order placement or managed accounts, or users whose main battleground lies outside its covered categories.
Does joining the Tenki Waitlist incur any charge?
No. The site states plainly: No card now — you're just claiming your spot. Signup is free with no card required, and comes with launch-priority access plus about 2 weeks free after launch; decide on a paid subscription then.
