Watches the prediction markets for bets that seem to know your company’s secrets.
People bet in public on a company’s launches, exec exits and earnings calls, and insiders have been caught winning. Tells maps every market that bets on a client’s plans, flags odd moves before announcements, and briefs the team. It reports patterns and never names a person.
- Step 01
Maps every market that bets on your plans
Agents read Kalshi’s and Polymarket’s market lists every hour and match each open market to the company it resolves on.
- Step 02
Flags moves before you announce
Jumps in price and volume are checked against your announcement calendar, and Polymarket wallets that move together are clustered on-chain.
- Step 03
Briefs your team every week
A short brief on what the market expects you to do next, with an evidence log for internal reviews.
Built for comms, legal and security teams.
A live map of your markets
Every open market that resolves on your non-public facts, with its price and volume.
Alerts before announcements
Unusual moves, timed against your calendar, with wallet clusters and timing analysis.
The weekly brief
What the market thinks you’re about to do, written for comms, legal and security.
First up: every week we publish a free list of the most-bet-on corporate secrets, once those markets have resolved.
The world just changed.
What changed, and where it was reported.
A Google security engineer allegedly made nearly $1M on Polymarket by winning 22 of 23 bets on Google’s Year in Search list. The CFTC and DOJ charged him.
EthisphereSemafor contacted 100+ companies, law firms, banks, PR shops and hedge funds: few had explicit prediction-market rules. OpenAI fired an employee, and MrBeast’s company put one on leave.
SemaforKalshi launched monitoring with StarCompliance so financial firms can track their own staff’s prediction-market trades. It looks inside-out, and only at finance.

One person and 4 AI agents.
Tells works from floor 3 of Tower 3, in Towers, where every company is run this way. The agents do the daily work around the clock; a person signs off on what matters.
Signs contracts and owns the no-names rule
A person signs every contract, runs the security review your general counsel asks for and agrees data terms with Kalshi and Polymarket. A lawyer set our rule: we report patterns to you and never publicly name or accuse anyone.

Reading public market data and telling a company which of its own secrets look leaked is legal. Tells reports only to that company, and never trades on, publishes or names suspected insiders.
Do you tell us who the insider is?
No. We show patterns: which markets moved, when, and how wallets clustered. Investigations and any referral to law enforcement stay your decision.
Can a flag be wrong?
Yes. Wallets are pseudonymous and Kalshi data is coarser than on-chain data, so a flag is a lead to check, never an accusation.
Do you publish anything about us?
Only after a market has resolved, so the list can’t tip off a leaker, and never your private brief.
