Kalshi Review 2026

Is Kalshi Legit and Safe?

Yes. Kalshi is a CFTC Designated Contract Market (DCM) — the same federal license class as CME Group — continuously active since 2021. It maintains segregated customer funds, operates in all 50 US states, and generated $263.5M in fee revenue in 2025 at a $22B valuation (March 2026). The App Store rating (4.8/5, 282,000+ ratings) reflects the actual user experience. Kalshi is the most-regulated retail prediction market in the US.

What Is Kalshi?

Kalshi is a CFTC Designated Contract Market (DCM) — the only fully regulated US exchange offering retail investor access to event contracts on macroeconomic indicators: monthly CPI reports, FOMC interest rate decisions, quarterly GDP readings, and unemployment data.

The platform was founded in 2018 by Tarek Mansour and Luana Lopes Lara, both former Goldman Sachs employees. Kalshi raised a Series E at an $11 billion valuation in 2025, backed by Sequoia Capital, Y Combinator, and a group of institutional investors. It generated $263.5M in fee revenue in 2025 — a figure that includes sports market revenue, which represents the majority of overall volume.

The inflection point for Kalshi's institutional standing came in January 2026, when Federal Reserve economists published a research paper analyzing Kalshi's CPI and FOMC market data from 2021 to 2025. The finding: Kalshi's market-implied probabilities outperformed Bloomberg consensus forecasts for both the monthly CPI print and FOMC rate decisions. It was the first peer-reviewed validation of a CFTC-regulated prediction market as a superior macroeconomic forecasting tool.

That research transformed the perception of Kalshi among serious investors — from "interesting fintech product" to "empirically validated economic intelligence tool." This review is written for that audience.

Pros and Cons

Fee Structure: The Exact Formula

Kalshi's fee is not a flat percentage. It is a per-contract formula published on kalshi.com/docs/fees. Understanding it matters because the fee changes with contract price — trading at 50¢ costs materially more than trading at 10¢ or 90¢.

Fee = 0.07 × number_of_contracts × price × (1 − price)

Taker fee cap: $1.75 per 100 contracts
Maker fee cap: $0.44 per 100 contracts

The shape of price × (1 − price) is a parabola that peaks at price = 0.50 and falls to zero at the extremes. That is why uncertain contracts cost more to trade: Kalshi charges the most where the most information is priced in.

Worked examples

Three concrete trades, each 100 contracts, to show what the formula returns in practice:

Read the table this way: a trader who buys 100 contracts at 30¢ pays $1.47 in taker fees (0.07 × 100 × 0.30 × 0.70 = 1.47). At 50¢ the raw formula yields 0.07 × 100 × 0.50 × 0.50 = $1.75 — which is also where the taker cap bites, so any 100-contract trade priced between roughly 35¢ and 65¢ pays the $1.75 cap rather than the formula value. At 90¢ the cost drops to $0.63. Maker orders (resting limit orders that provide liquidity) pay the same formula but with a much tighter $0.44 cap per 100 contracts — which is where nearly every maker trade sits.

Fee comparison to competitors: At the $1.75-per-100-contracts cap, Kalshi's effective taker rate is ~1.75% on a $100 notional — slightly above Polymarket US's Θ=0.06 formula cap of ~$1.50 per 100 contracts (which also pays maker rebates), and far below PredictIt's 10% of profits plus a 5% withdrawal fee. For investors who cannot or will not custody USDC (which Polymarket requires), the Kalshi-vs-Polymarket comparison does not apply. For active macro trading in USD, Kalshi's cap-plus-formula structure is predictable and bounded.

Cash APY: Interest on Idle Collateral (3.75–4%)

Kalshi pays 3.75–4.00% APY (as of 2026-Q1) on uninvested USD collateral sitting in your account — interest credited monthly on balances that have not been deployed into open contract positions. This feature is unique among retail prediction markets in the US. Polymarket pays 0% on USDC balances because on-chain stablecoins do not earn native interest. PredictIt pays nothing on deposited USD. Fanatics Markets and Underdog do not advertise any yield.

For macro investors sizing positions ahead of CPI / FOMC / GDP releases, the practical implication is material: capital that is waiting for the right entry earns a competitive money-market yield rather than sitting idle. A $25,000 idle balance generates roughly $940–$1,000/year in interest at the current rate — effectively offsetting a meaningful share of round-trip trading costs across active positions.

Rates are set unilaterally by Kalshi and can change with Fed policy or platform economics. Verify the current APY at kalshi.com before assuming it for portfolio planning. This is not FDIC-insured — it is interest paid by Kalshi on funds held in the exchange's segregated accounts, backed by Kalshi's own treasury management.

Economic Markets: The Investor Differentiator

Kalshi's economic indicator contracts are the primary reason this site exists. No other CFTC-regulated prediction market platform offers these markets. Here is what is available and how to use each:

The CPI market is the most widely used by institutional observers. Kalshi structures it as a series of binary contracts covering different outcome ranges — for example: "Will March 2026 CPI print 3.0%–3.4%?" Each contract's price is the market-implied probability of that outcome. The full set of contracts forms a probability distribution over all possible CPI readings.

This distribution is more informative than a Bloomberg consensus point estimate. If the consensus is 2.8% but Kalshi's distribution shows 38% probability at 3.0% or above, the market is communicating meaningful upside inflation risk that the consensus number obscures. Portfolio managers who use this signal can size inflation hedges accordingly before the BLS release.

The FOMC market works similarly, with contracts on each possible rate outcome at each meeting (hold, +25bps, +50bps, -25bps, etc.). The implied probability distribution is a continuous, real-time complement to the CME FedWatch tool — and per the Fed's own research, more accurate.

Regulatory Status and Trust Signals

Kalshi's regulatory profile is the strongest in the retail prediction market space:

• CFTC Designated Contract Market (DCM) since 2020 — same license class as CME Group, CBOE, and other major US derivatives exchanges. Requires meeting 23 CFTC Core Principles covering financial surveillance, customer fund segregation, position limits, and audit trail maintenance.
• Available in all 50 US states — unlike Fanatics Markets (23 states + 4 US territories) and Underdog (33 states), Kalshi's DCM license provides nationwide access without state-by-state regulatory negotiation.
• $263.5M in fee revenue (2025) — financially stable, not solely dependent on venture funding. Sports markets generate the majority of this revenue, but the economic indicator markets operate from the same regulatory and financial infrastructure.
• App Store: 4.8/5 (iOS, 282,000+ ratings) — a large and representative sample. Use this for trust assessment, not Trustpilot (see below).
• Federal Reserve validation (January 2026) — Fed economists explicitly studied and validated Kalshi's forecasting accuracy. This is not a marketing claim; it is a peer-reviewed research finding.

A Note on the Trustpilot Rating

Kalshi's Trustpilot score is 2.4/5 based on approximately 90 reviews. We do not use this in our scoring, and we advise investors to disregard it for the following reasons:

The Trustpilot sample is dominated by complaints about ACH withdrawal delays (a banking infrastructure issue affecting US fintechs broadly) and a small number of unauthorized charge disputes. Neither issue is related to the economic trading experience. Trustpilot's review mechanism also attracts disproportionate participation from dissatisfied users — the 282,000+ investors who use Kalshi's mobile app and rate it 4.8/5 are simply not filing Trustpilot reviews.

We use the App Store rating as our UX trust signal. It is three orders of magnitude larger, represents active platform users rather than a Trustpilot-aware subset, and reflects the mobile experience that most Kalshi users actually have.

Tax Reporting: The Operational Advantage

Kalshi provides IRS Form 1099 to all US traders with taxable activity. The form is generated automatically and made available through the Kalshi platform dashboard by the standard IRS deadline. It covers net gains and losses across all contract categories.

For context: Polymarket does not issue a 1099. PredictIt deducts 10% on profits at the platform level but provides no 1099. Opinion Trade has no US tax reporting infrastructure.

Two additional considerations for tax-aware investors:

1. Section 1256 potential: Contracts traded on CFTC-designated contract markets may qualify for Section 1256 treatment — which taxes gains 60% as long-term capital gains and 40% as short-term, regardless of holding period. Whether Kalshi's specific contracts qualify depends on their structure. Consult a tax professional who has reviewed the relevant IRS guidance on Section 1256 contracts and Kalshi's contract terms.
2. Mark-to-market accounting: Section 1256 contracts, if applicable, require mark-to-market accounting at year-end — open positions are treated as if closed at fair market value on December 31. This affects year-end tax planning for active traders with significant open positions.

Withdrawing from Kalshi

Withdrawals are where most new Kalshi users hit friction, and where Kalshi's 2.4/5 Trustpilot rating originates. The good news: the mechanics are simple, there are no platform fees, and processing times are in line with the wider US fintech norm for ACH. The bad news: first-time withdrawals are slower than subsequent ones because of secondary KYC checks. Here is the full picture.

Supported methods

• ACH to a linked US bank account — the default method for most users. Requires linking a bank via Plaid or manual routing/account number. No fee.
• Wire transfer — used for larger withdrawals or when ACH limits are insufficient. Kalshi does not charge a wire fee; your receiving bank may. Faster settlement (same-day / next-day) than ACH.
• Robinhood / Webull users — funds withdraw through the host brokerage's standard cash-sweep and payout flow, not directly from Kalshi. 1099 reporting also flows through Robinhood/Webull in that case.

Always confirm the current list of supported methods on help.kalshi.com before initiating a withdrawal — the payment-rails landscape for CFTC DCMs can shift with banking-partner changes.

Processing time, fees, limits

• Typical processing: 1–3 business days for ACH; same-day or next-business-day for wires. Weekends and bank holidays extend the window.
• Platform fees: None. As of April 2026, Kalshi does not charge a fee for ACH or wire withdrawals per the published fee schedule. Your receiving bank may charge an incoming-wire fee on larger wires — check with your bank.
• Minimum withdrawal: Effectively $10 (matches the minimum deposit); Kalshi does not publish a higher floor.
• Maximum withdrawal: Kalshi does not publish a hard cap for most accounts. Very large withdrawals may be reviewed under standard CFTC DCM anti-fraud surveillance before being released — consistent with any regulated exchange.

Tax form issuance

At year-end, Kalshi issues IRS Form 1099 (typically 1099-B for contract trading activity) to any US trader with reportable activity for the year. The form is posted to your Kalshi dashboard by the standard IRS deadline (late January / early February for the prior tax year), and the IRS receives a copy directly — you do not need to forward it. Because Kalshi is a CFTC-designated contract market, Section 1256 60/40 long-term/short-term treatment may apply to qualifying contracts; consult a tax professional who has reviewed your specific trading history. Contrast: Polymarket, PredictIt, and Opinion Trade do not issue 1099s, leaving tax tracking to the user.

Common withdrawal issues

These are the issues that drive the Trustpilot complaint volume. None are deal-breakers, but knowing them upfront saves a support ticket:

• Delayed first withdrawal. Your first withdrawal typically takes 3–5 business days instead of 1–3 because Kalshi runs a secondary KYC re-verification on the outbound payment rail. This is a CFTC DCM compliance step, not a Kalshi-specific delay tactic. Plan your first cash-out around this.
• Same-day bank-linking deposits. If you link a bank and fund the account on the same day, those specific funds are usually held for a short settlement window before being withdrawable. Deposits made via an already-established link do not have this hold.
• Account-value freezes during disputes. If you open a chargeback or dispute against a Kalshi deposit at your bank, Kalshi freezes the withdrawable balance until the dispute resolves. This is industry standard across CFTC DCMs and is not specific to Kalshi — but it shows up in Trustpilot complaints as "Kalshi froze my account."
• KYC re-verification on large withdrawals. Withdrawals that meaningfully exceed your typical pattern may trigger a one-time identity re-verification. Submitting the requested documents promptly clears it in 1–2 business days.

How Does Kalshi Make Money?

Investors evaluating Kalshi should understand its revenue model before committing capital — because a platform's incentives shape its long-term behavior toward users. Kalshi's 2025 fee revenue was $263.5M, and its business model is unambiguous: it is an exchange that earns on trading activity, not a broker that earns on your directional bets.

Primary revenue: transaction fees

The bulk of Kalshi's revenue is the per-contract fee documented above — 0.07 × contracts × price × (1 − price), capped at $1.75 per 100 contracts for takers and $0.44 per 100 contracts for makers. At scale across billions of contracts traded per quarter (sports + economic + political), this is the engine. The fee cap keeps large institutional trades profitable for the user while keeping Kalshi's revenue proportional to activity rather than notional size.

Market-making spread (as an exchange, not a broker)

Kalshi is a CFTC-registered exchange — a Designated Contract Market — not a broker. That distinction matters for how it earns. Unlike a broker that takes the other side of customer trades (and therefore profits when customers lose), Kalshi runs a central limit order book where buyers and sellers transact with each other. Kalshi earns on the spread between resting bids and offers via its own designated-market-maker arrangements, but it does not warehouse customer risk or take directional positions against user flow. This is structurally closer to CME Group or CBOE than to Robinhood.

Institutional and API pricing

Kalshi offers a separate institutional pricing tier for API-based traders (market makers, hedge funds, quant shops) — including volume-based rebates and co-location arrangements. Specific rates are negotiated and not publicly listed. This tier, combined with Platinum-program retention perks for high-volume retail, accounts for the long tail of platform revenue beyond retail fee capture.

Not a revenue source: interest on customer deposits

This is the cleanest contrast to Robinhood's model. Robinhood earns a material share of revenue on the interest differential between customer cash balances and the rate it pays users. Kalshi does not: the 3.75–4% APY it pays on idle collateral is returned to users, not retained as net interest income. Kalshi does earn on its own corporate treasury (segregated customer funds must be held in qualifying institutions under CFTC rules, and Kalshi captures any yield spread above what it pays users), but customer-facing product economics do not depend on suppressing the user's interest rate. There is no asset-management business, no payment-for-order-flow in the equities sense, and no proprietary trading book against customer orders.

Kalshi on Robinhood and Webull

In 2025, Kalshi launched distribution partnerships with Robinhood and Webull, allowing their combined user base of 25M+ to access Kalshi's event markets directly from existing brokerage accounts.

This matters for investors for several reasons:

• No new account required — same login, same funding, same portfolio view as existing stock/ETF holdings
• Tax reporting flows through existing Robinhood/Webull 1099 infrastructure
• Prediction market positions visible alongside traditional investment positions — enabling more integrated portfolio analysis

For investors already on Robinhood or Webull, this is the lowest-friction path to Kalshi access. For investors not on these platforms, opening a Kalshi account directly takes approximately 10 minutes with standard KYC documentation.

Who Kalshi Is Best For

Kalshi IS the right choice if you:

• Are a macro investor, portfolio manager, or trader who wants to use CPI and FOMC markets as portfolio positioning tools
• Are US-based and prefer USD deposits with no crypto wallet requirements
• Need IRS Form 1099 for tax filing — or want to minimize year-end tax compliance burden
• Are an existing Robinhood or Webull user seeking the path of least friction
• Prioritize regulatory certainty — Kalshi's 5-year CFTC DCM track record is the strongest in retail prediction markets
• Trade event markets across politics, economics, and sports from a single regulated venue

Kalshi is NOT the right choice if you:

• Are outside the US — Kalshi is US-only with strict geofencing
• Are a crypto-native trader comfortable with USDC and non-custodial wallets who prioritizes fee minimization — Polymarket's taker cap (~$1.50 per 100 contracts) is modestly lower, and it pays maker rebates
• Primarily trade international political events (non-US elections, geopolitical developments) — Polymarket's global coverage is far superior
• Are a political market specialist who values historical data depth over economic indicator access — PredictIt has operated US political markets since 2014

Final Verdict

Kalshi is the top pick for macro investors and anyone who wants regulatory certainty. Its exclusive CFTC-approved economic indicator markets — CPI, FOMC, GDP — are unavailable anywhere else, and Federal Reserve research validates their forecasting accuracy over Bloomberg consensus. If you trade with USD, want 1099 tax reporting, and need all-50-state access, Kalshi is the clear choice.

The 4.6/5 score reflects that Kalshi is nearly optimal for macro investors — losing marginal points only for its US-only access (which limits applicability for international readers) and its taker fee structure (which is higher than Polymarket's, though only relevant for traders who can access Polymarket via USDC).

If you are reading this as a US-based investor looking for a regulated, USD-native platform to trade economic indicators with automated tax reporting, Kalshi is the correct answer. There is no competitor for this specific use case.
