Our Take
Polymarket has the highest liquidity and the broadest global market selection of any prediction market in existence. The CFTC-regulated U.S. relaunch (December 2025) is genuine — and U.S. users currently have access to sports markets via QCX LLC, with politics, crypto, economics, and other categories coming soon. Access is still via invite-only waitlist with USDC-based infrastructure and fiat on-ramps. If you want the deepest markets and are comfortable with crypto mechanics, Polymarket is the right platform. If you need plug-and-play USD, Kalshi is cleaner.
Key Strengths
Highest Global Liquidity
Polymarket consistently leads all prediction markets by trading volume. Deep order books on major political, economic, and sports events mean tighter spreads and better fills.
Broadest Market Selection
1,000+ markets across politics, economics, sports, crypto, science, entertainment, and culture. More event categories than any U.S. competitor.
CFTC-Regulated (US Relaunch)
QCX LLC (d/b/a Polymarket US) received CFTC DCM designation on July 9, 2025 (acquisition closed July 21, 2025). The amended order renaming it Polymarket US was issued November 25, 2025. U.S. residents can now trade legally under federal oversight.
Geopolitics Markets Are Fee-Free
Geopolitical and world events markets carry zero trading fees. Fees apply to crypto (up to 1.80%), sports (up to 0.75%), politics, economics, finance, culture, tech, and other categories. Makers always receive rebates.
No Crypto Required
U.S. users can deposit via credit card, bank transfer, Coinbase Pay, or Robinhood Connect. The USDC conversion happens automatically — no crypto wallet needed.
iOS App Available
Polymarket launched its iOS app December 3, 2025. Mobile experience is solid with real-time pricing and portfolio tracking.
Key Considerations
US Access Is Invite-Only / Waitlist
As of April 2026, U.S. access is rolling invitations — not fully public. You may need to wait weeks or months for access.
MoonPay Card Deposits: ~4% Fee
Depositing via credit or debit card runs through MoonPay with approximately a 4% conversion fee. Not from Polymarket, but it's real and material for smaller deposits.
USDC Infrastructure Learning Curve
Funds are held as USDC on Polygon. Withdrawals go to a wallet. If you've never used a crypto wallet, there's a learning curve — though fiat on-ramps reduce day-to-day friction.
No Fund Segregation (Smart Contract Custody)
Unlike Kalshi, funds are held in smart contracts — not segregated bank accounts. This is different risk, not necessarily worse, but important to understand.
No Leverage
All positions are fully collateralized. No margin or leverage available.

What Is Polymarket?
Polymarket is the world's largest prediction market by trading volume— a platform where you trade event contracts on real-world outcomes. Founded in 2020 by Shayne Coplan, Polymarket grew into a global platform with over 1,000 active markets before re-entering the U.S. market in late 2025.
After a 2022 CFTC settlement ($1.4M, January 2022) that required U.S. users to be blocked, Polymarket returned through an entirely new regulatory path. In July 2025, Polymarket acquired QCX LLC for $112M. The CFTC approved Polymarket's amended operational structure in November 25, 2025, making QCX LLC (d/b/a Polymarket US) a designated contract market under federal law.
Each contract trades between $0.01 and $0.99 and represents the market's implied probability of an outcome. Contracts are priced in USDC — a stablecoin pegged to the U.S. dollar. U.S. users can deposit fiat through card, bank transfer, Coinbase Pay, or Robinhood Connect without ever owning crypto directly.
The international Polymarket platform (not available to U.S. residents) offers the full 1,000+ market catalog. Polymarket US is currently sports-focused, with politics and other categories listed as coming soon.
Regulatory Note
Polymarket operates as a CFTC-regulated DCM through QCX LLC (d/b/a Polymarket US). Polymarket acquired QCX LLC for $112M in July 2025. CFTC approved operations via amended order November 25, 2025. U.S. users access Polymarket through the Polymarket US venue (QCX LLC). The international platform operates separately and is not available to U.S. residents. In April 2026 (announced April 20), Polymarket raised at a $15 billion valuation.
Market Categories
Polymarket's platform has the broadest market catalog of any prediction market. U.S. residents on Polymarket US (QCX LLC) currently see sports markets only (NFL, NBA, NHL, MLB, college, soccer, UFC). Politics, crypto, economics, culture, and geopolitics are listed as coming soon per the official App Store listing.
US Users: U.S. users should verify the live Polymarket US product directly before funding an account. Sports markets are the clearest current category, and broader rollout should be treated as product-dependent until it is live on the current U.S. venue.

Fees
Polymarket's fee structure is tiered by market type. Only geopolitics/world events markets are fee-free. Crypto markets carry up to 1.80% taker fee; sports up to 0.75%; politics, finance, tech up to 1.00%; economics, culture, weather up to 1.25%. Makers receive rebates on all fee-enabled markets. On the CFTC-regulated On the CFTC-regulated Polymarket US (sports) venue, sports markets carry a probability-based taker fee peaking at 0.75% at 50/50 odds (near-zero for heavy favorites or underdogs). Makers receive a 25% rebate. As of March 30, 2026, the sports taker fee increased from 0.44% to 0.75% at 50¢ price.
In plain English
Most bets on Polymarket are completely free. They only charge fees on crypto price predictions (up to about 1.8 cents per dollar at 50/50 odds) and a few sports markets (less than half a cent per dollar). If you place limit orders instead of market orders, you actually get paid back — makers never pay fees.
On the US-regulated version, you pay 30 cents for every $100 you trade. If you place limit orders instead of market orders, you actually get paid 20 cents back per $100.

Sports Fee Detail
All sports markets (effective March 30, 2026) — trading fee formula: C × p × 0.0175 × (p × (1-p)). Max effective rate: 0.75% at 50¢ at 50¢ price. Makers receive 25% rebate.
In plain English: Up to 0.75 cents per dollar on sports markets (raised from 0.44% on March 30, 2026). On a $100 position at 50¢, you'd pay about 75 cents in fees.
Crypto Fee Detail
All crypto direction markets (15-min, 5-min, 1H, 4H, daily, weekly — expanded March 6, 2026). Trading fee formula: C × p × 0.25 × (p × (1-p))². Max effective rate: 1.80% at 50¢. Makers receive 20% rebate. Peak effective rate raised March 30, 2026 (was 1.56%)
In plain English: Up to about 1.8 cents per dollar at 50/50 odds on crypto price prediction markets. On a $100 position at 50¢, you'd pay about $1.80 in fees (raised from 1.56% on March 30, 2026).
Hidden Cost: MoonPay Card Deposits
Depositing via credit or debit card runs through MoonPay, which charges approximately 4% for fiat-to-USDC conversion. This fee is from MoonPay, not Polymarket, but it's real. For deposits under $100, it's significant. Use Coinbase Pay, bank transfer, or direct USDC to avoid it.
Deposits & Withdrawals
U.S. users can fund Polymarket without owning crypto. Multiple fiat on-ramps convert dollars to USDC automatically. Withdrawals go back to a wallet or exchange — not a bank account directly. Here's the full picture:
| Method | Timeframe | Fee |
|---|---|---|
| Credit/Debit Card (MoonPay) | Instant deposit | ~4% MoonPay conversion fee |
| Bank Transfer | 1–3 business days | None from Polymarket |
| Coinbase Pay / Robinhood Connect | Near-instant | None from Polymarket |
| Direct USDC (Polygon) | ~1 minute (chain confirmation) | Polygon gas ~$0.01–$0.05 |
| Withdrawal (to wallet) | Minutes (Polygon) | Polygon gas ~$0.01–$0.05 |
Withdrawal Reality Check
Withdrawing from Polymarket sends USDC to a crypto wallet — not a bank account. To convert back to dollars, you'll need to sell USDC on an exchange (Coinbase, Robinhood, etc.) and then initiate a bank transfer. This adds a step compared to Kalshi's direct bank withdrawal.
Institutional Partnerships & Ecosystem
Polymarket has rapidly become the most partnership-dense prediction market platform on earth — with exclusive sports league deals, institutional investment, AI infrastructure partnerships, data integrations, and a growing acquisition portfolio.
Sports & Media Partnerships
MLB (Major League Baseball)
Exclusive Prediction Market Exchange Partner
MLB named Polymarket its exclusive prediction market exchange partner. The CFTC and MLB also signed a first-ever Memorandum of Understanding for sports integrity (March 19, 2026) — the first time the CFTC has signed an MOU with a professional sports league.
Institutional & Technology Partners
Acquisitions (2025–2026)
Why This Matters
MLB, La Liga, MLS, ICE, Palantir, Dow Jones, and Google aren't casual partnerships — they're the architecture of a legitimization campaign. The CFTC-MLB MOU is particularly significant: it's the first time the federal derivatives regulator has formally partnered with a professional sports league on prediction market integrity.
Liquidity & Execution
Polymarket leads all prediction markets on liquidity. For major political and economic events, Polymarket typically has millions of dollars in volume per market with spreads under 2 cents. Even for mid-tier markets, depth is better than on any U.S. regulated alternative.
High Liquidity
- • US presidential elections
- • Fed rate decisions
- • BTC / ETH price milestones
- • Major geopolitical events
Spreads: 1-2¢
Medium Liquidity
- • Congressional races
- • Sports events (NFL/NBA)
- • International politics
- • CPI / GDP data
Spreads: 2-5¢
Low Liquidity
- • Niche international events
- • Far-dated contracts
- • Emerging market politics
- • Very new markets
Spreads: 5-15¢+
Execution on Polymarket is on-chain (Polygon), which means fills are fast (under a minute for most orders) but not instantaneous like a centralized exchange. For large positions, check order book depth before placing. Market orders execute at the current best available price.

Trust & Resolution Rules
Polymarket's trust model is different from Kalshi's. Funds are held in smart contracts on Polygon — not in segregated bank accounts. Resolution is governed by UMA Protocol, a decentralized oracle system with its own dispute process.
Smart Contract Custody
Funds are held in audited smart contracts on Polygon — not by Polymarket directly. Polymarket cannot unilaterally freeze or seize your funds. This is a different trust model from custodial platforms, with its own tradeoffs.
UMA Protocol Resolution (International)
International markets resolve via UMA's decentralized oracle. Disputes can be escalated through UMA's dispute process, and outcomes are determined by UMA token holders as a last resort. The system is transparent and on-chain.
CFTC Oversight (US Venue)
Polymarket US (QCX LLC) operates under CFTC oversight as a designated contract market. This adds regulatory accountability for U.S. users that the international platform did not have.
Edge Case: Market Cancellations
Polymarket has voided markets where resolution was contested or unclear (e.g., pre-taped show markets where outcomes were known in advance). The decentralized resolution system provides transparency but isn't immune to disputes. Check the resolution source on each contract before trading.
Edge Case: Resolution Disputes
When sources are delayed or ambiguous, UMA token holders vote. This process is transparent and on-chain but can take time. For international markets, the dispute window and process differ from Kalshi's centralized rules — read the contract resolution criteria carefully, including any fallback clauses that can flip a market to 50-50 if the trigger event doesn't occur in time.
Smart Contract vs Segregated Funds
Polymarket funds sit in audited smart contracts. Kalshi funds are held in segregated accounts at regulated banks. Neither is inherently superior — they're different risk models. Smart contracts are transparent and non-custodial; segregated accounts have CFTC-mandated protections and are more familiar to traditional investors.
Taxes
Polymarket taxation involves two layers: event contract gains (like Kalshi) and potential crypto-related tax treatment (USDC is pegged to USD but its treatment can vary). Here's what to know for 2026.
1099 Reporting
Polymarket US (QCX LLC) may issue tax forms as required under applicable law for U.S. users. Tax reporting obligations are still being defined as the platform is new in the U.S. market.
Ordinary Income (Likely)
Event contract gains are generally treated as ordinary income. USDC pegs to USD so gains from the stable value itself are minimal, but any appreciation or trading gains may be taxable as ordinary income.
Tax Disclaimer
This is general information, not tax advice. Polymarket's USDC-based structure adds complexity vs. pure USD platforms. Keep records of all deposits, trades, and withdrawals. Consult a qualified tax professional familiar with both event contracts and crypto taxation.

Who Should Use Polymarket?
Best For
High-volume traders who need deep liquidity
Polymarket's order books are the deepest in prediction markets globally. If you're moving significant size, this is where the liquidity lives.
Sports bettors exploring prediction markets
Polymarket US currently focuses on sports. If you're a sports bettor who wants to understand prediction markets, this is the most relevant U.S. option right now.
International traders and crypto-native users
The global Polymarket platform has the widest market selection and works natively with USDC. Crypto-comfortable users will find it intuitive.
Traders who want the broadest market catalog
If you want to trade on global events, international politics, or niche outcomes, Polymarket's international platform has no peer.
Not Ideal For
Traders who want immediate open access
Polymarket US access is still invite-only via waitlist as of April 2026. If you need instant account access, Kalshi is open to eligible US users without a waitlist.
Traders who want simple USD deposits and withdrawals
Withdrawals go to a USDC wallet, not a bank account. Converting back to dollars requires an extra step via a crypto exchange. Kalshi is simpler for USD-only flows.
Users who can't get off the waitlist
U.S. access is invite-only rolling invitations as of April 2026. You may not be able to use Polymarket US immediately.
Traders who want traditional custody
Polymarket uses smart contract custody on Polygon — not segregated bank accounts. If you prefer traditional regulated fund protection, Kalshi's model is closer to a traditional exchange.
Summary
Polymarket is the largest and most liquid prediction market on the planet. The December 2025 U.S. relaunch via QCX LLC (CFTC-regulated DCM) is a genuine milestone — but U.S. access is currently limited to sports markets on a waitlist basis. The international platform has unmatched depth and breadth, but is not available to U.S. residents.
The core tradeoff: Polymarket gives you the best liquidity and broadest markets, but you trade in USDC (not USD directly), withdrawals require a crypto wallet step, and U.S. users are currently constrained to sports. If those tradeoffs work for you, Polymarket is the best market in the world. If they don't, Kalshi is the cleaner USD-first alternative with a broader U.S. market menu today.
