Mentat vs Kalshi
CFTC-regulated event contracts — full compliance, full centralization.
Context
Kalshi is the first US-regulated event contracts exchange, operating under CFTC oversight as a designated contract market. The result is full legitimacy with US institutional users and zero permissionless surface area. Markets are listed by Kalshi staff, settled by internal data review, and traded only by KYC US residents. Mentat is the opposite tradeoff.
At a glance
| Dimension | Mentat | Kalshi |
|---|---|---|
| Regulatory posture | Permissionless protocol; jurisdiction = front-end concern | CFTC-regulated DCM |
| Settlement | On-chain zkTLS proof | Staff review |
| Market creation | Permissionless + curated | Staff-listed |
| User access | Global, wallet-only | US KYC only |
| Auditability | On-chain accounts + proof artifacts | Internal records |
| License | Apache-2.0 | Proprietary |
Resolution
Kalshi resolves markets via internal staff review of designated data sources. There is no on-chain settlement, no public proof, and disputes route through Kalshi customer service. For regulated US event contracts this is fine. For permissionless markets it is the wrong architecture. Mentat resolves through verifiable zkTLS proofs against the same kinds of canonical sources Kalshi uses internally — but the verification is public and on-chain.
Market creation
Kalshi markets are listed by Kalshi staff after CFTC review. A self-listing pathway exists in principle but is heavily gated. Mentat lets any user draft a market through the AI pipeline; curators approve quality; the protocol deploys to Solana.
Jurisdiction
Kalshi is US-only and KYC-mandatory. Mentat is permissionless at the protocol level. Any deployment can layer its own jurisdiction-specific compliance on top; the base protocol does not assume one.
Liquidity
Kalshi has institutional market makers and reasonable depth on flagship markets. Mentat will need to bootstrap liquidity post-M5; we are honest about that.
Chain & economics
Kalshi is centralized off-chain. Mentat is on Solana.
When to choose what
Choose Kalshi if you are a US institution that needs CFTC-regulated, KYC-compliant event contracts and you are willing to pay for centralized settlement. Choose Mentat if you want permissionless, cryptographically-settled, globally accessible markets.
FAQ
Is Mentat a Kalshi replacement?
No — they solve different problems. Kalshi is the right answer for US-regulated institutional event contracts. Mentat is the right answer for permissionless, on-chain, cryptographically-settled markets.
Could a Kalshi-style operator use Mentat under the hood?
Yes. A regulated operator could deploy the protocol as their on-chain settlement layer while running KYC + market listing through their own compliance stack.
