Kalshi vs Robinhood, Polymarket, PredictIt: How the Platforms Compare

A verification-first comparison of Kalshi, Robinhood event contracts, Polymarket, PredictIt, and sportsbooks. Historical regulatory records are separated from facts that must be checked in each platform's current terms.

By Kalshi View Editorial Team · Published August 10, 2026 · Corrected August 12, 2026

Quick answer: The CFTC designated KalshiEX as a contract market in 2020 and entered an enforcement order involving the operator then doing business as Polymarket in 2022. CFTC records also document PredictIt's no-action-relief history. Those dated records do not establish any platform's current access, products, fees, limits, liquidity, or custody. Robinhood and every other current offering must be checked in the exact contract disclosure.

Robinhood event contracts	No frozen product claim is made on this page	Exact legal entity, venue, contract terms, availability, fees, limits, and settlement procedure

PredictIt	CFTC record concerning no-action relief	Current operating status, available markets, eligibility, limits, fees, and settlement terms

Kalshi vs Robinhood event contracts

CFTC DCM

Kalshi

The 2020 CFTC order establishes KalshiEX's designation as a contract market. For an actual trade, the current market page and full rule text must establish the contract, order mechanics, limit, close time, determination source, and payout.

Open the exact market rules, not only the title.
Check the live spread and depth for the intended quantity.
Use the current official fee schedule and order preview.
Confirm the named source and determination procedure.

Brokerage

Robinhood

Do not infer a venue, carrying entity, limit, fee, or settlement process from the Robinhood brand alone. Open the exact current event-contract disclosure on Robinhood's official platform and record the terms that apply to that contract.

Identify the legal entity and execution venue.
Check eligibility and geographic restrictions.
Read fee, limit, funding, and settlement disclosures.
Compare the same event and deadline, not similar headlines.

Comparison rule: compare exact contracts, not logos. Two products can reference the same event while using different deadlines, definitions, source agencies, fees, limits, and dispute procedures.

Kalshi vs Polymarket

The CFTC's January 2022 order is evidence about conduct and registration at that time. It is not a current product sheet. A present-day comparison must separately verify operator identity, eligible jurisdictions, custody, funding, fees, market resolution, dispute procedures, and contract availability from official current sources.

What does the CFTC record say about PredictIt?

CFTC documents record the no-action-relief framework and a later withdrawal decision associated with PredictIt. This page does not turn that historical record into a claim that PredictIt is currently open, closed, listing, or not listing markets. Those facts require a dated current source.

Event contracts vs sportsbook wagers

Products can reference the same sports outcome without being interchangeable. Compare the legal entity, venue, applicable regulator, exact payout rule, fees or embedded spread, position limit, dispute process, account protections, and jurisdiction rules. Tax treatment is fact-specific; this page makes no categorical tax claim.

Risk checklist for every platform

Eligibility: confirm that the person, account, and location are allowed under current terms.
Contract: save the exact event definition, deadline, settlement source, and dispute procedure.
Execution: include displayed fees, bid-ask spread, depth, and partial-fill risk.
Custody and funding: identify who holds funds, withdrawal conditions, and whether any insurance statement actually applies.
Loss: calculate the maximum loss and do not treat regulatory status as a performance guarantee.

Frequently Asked Questions

How is Kalshi different from Robinhood event contracts?

The durable official fact is that the CFTC designated KalshiEX as a contract market in 2020. Robinhood product availability, the carrying entity, venue, fees, limits, and settlement terms must be checked in the exact current contract disclosure. Compare products contract by contract rather than treating the brand names as interchangeable.

Is Kalshi better than Polymarket?

There is no source-backed universal answer. The CFTC's 2020 Kalshi designation order and its 2022 Polymarket enforcement order are historical regulatory records. They do not by themselves prove current access, liquidity, fees, custody, or product coverage. Verify the current official terms that apply to your jurisdiction.

What does the CFTC record say about PredictIt?

CFTC records document the no-action-relief framework and later withdrawal decision associated with PredictIt. A historical agency document should not be used as proof of the platform's current operating status, available markets, limits, or eligibility; verify those separately from current official sources.

Are event contracts the same as sportsbook wagers?

They can reference the same event but use different contracts, venues, rules, regulators, fee structures, and settlement procedures. Product classification and legal or tax consequences are jurisdiction- and contract-specific, so read the exact terms and obtain professional advice where needed.

What should I compare before choosing an event-contract platform?

Check current eligibility, the legal entity and venue, contract rules, named settlement source, fees, spread and depth, order types, position limits, custody and funding terms, dispute procedures, and withdrawal conditions. Save a dated copy of the exact terms used for the decision.

Does CFTC oversight remove trading risk?

No. Regulatory status does not insure a trading balance, guarantee liquidity, eliminate operational risk, or prevent a contract from settling against the position. Read the exact rules and calculate the full downside before trading.
