Best Prediction Market Platforms 2026

We scored every major prediction market platform across 9 categories — regulation, fees, liquidity, market selection, withdrawals, user experience, deposits, tax tools, and customer support. Each score follows our published methodology with defined rubrics and publicly documented criteria.

The field exploded in 2026. In March, three platforms mattered. As of July, we score eight — plus one FIFA-partnered newcomer we profile but haven’t scored — and monthly industry volume has hit roughly $24 billion. Here’s where they stand:

Every scored platform is legitimate. None is right for everyone — the best choice depends on where you live, what you want to trade, and how you want to fund your account. This page breaks down the differences.

Last updated: July 13, 2026 — added five 2026 entrants (OG, ProphetX, Underdog, Fanatics Markets, Novig) and the ADI Predictstreet profile; raised Polymarket to 7.1 after its US platform opened fully; updated state availability for the expanded sports-contract fights. | Scoring basis: Published rubrics, public fee schedules, regulatory filings, user review analysis, and community research.

Quick Comparison

How We Score Platforms

Every platform is evaluated across 9 weighted categories using defined rubrics. Regulatory safety carries the highest weight (20%) because if your money isn’t protected, nothing else matters. Fees, market selection, and liquidity each carry 15%. The full scoring framework, rubric definitions, and testing protocol are published on our methodology page.

Scores reflect what each platform is today, not what it may become. When platforms change — new features, fee adjustments, regulatory developments — we update scores and publish changelogs. Rankings follow scores, not affiliate commissions.

#1: Kalshi — Best Overall (7.4 / 10)

Kalshi remains the benchmark: the longest-running CFTC Designated Contract Market in the group, its own clearinghouse, legally mandated fund segregation, and the widest regulated market selection — politics, sports, economics, culture, crypto, climate, and more. Volume keeps validating the platform: June 2026 set a record above $31 billion in notional volume, up roughly 70% month-over-month on World Cup demand.

The weaknesses haven’t moved: withdrawals to a different bank can take up to 90 days, customer support has a documented pattern of non-responsiveness, and the state-level fight over sports contracts has widened — sports markets are now geofenced in seven states (AZ, IL, MA, MD, MI, MT, OH), and a July 2026 New York federal ruling let state gambling enforcement proceed. Non-sports categories remain available everywhere.

Best for: US residents who want the most regulated platform with the most to trade. Key scores: Regulation 9.0 | Markets 9.0 | UX 8.0 | Withdrawals 5.0 | Support 4.0

#2: Polymarket — Best Trading Mechanics, Now Open in the US (7.1 / 10)

The biggest rankings move of 2026. Polymarket US — run by QCX LLC under a CFTC exchange designation — ended its waitlist in May and opened to all US iOS users with debit card, Apple Pay, and bank funding. No crypto required. Taker fees max out at 1.25¢ per contract (cheaper than Kalshi’s formula), makers earn rebates, and liquidity remains the deepest in the industry: Kalshi and Polymarket combined cleared $44.8 billion in June.

What keeps it at #2: US access is iOS-only for now (Android and web pending), Nevada is paused, tax documentation is unconfirmed, and support remains the weakest of the major platforms. The global platform is still crypto-only and unavailable to US residents.

Best for: Fee-sensitive and high-volume traders, politics specialists, non-US residents (global platform). Key scores: Fees 9.0 | Markets 8.5 | Liquidity 8.0 | Support 3.0 | Tax 3.0

#3: OG — Best of the New Wave (6.7 / 10)

Crypto.com’s OG launched February 3, 2026 on serious infrastructure: North American Derivatives Exchange (Nadex), a CFTC-registered exchange and clearinghouse with federal registrations since 2004. The funding stack is the broadest in the field — PayPal, Venmo, Apple Pay, Google Pay, instant bank — and the market slate spans sports (with four-leg parlays), politics, economics, crypto, forex, and culture. Settlement is free: hold to expiry and pay nothing beyond the 2¢-per-contract open fee.

The gaps are trader-facing: no limit orders (everything executes at market), no visible order book, ACH-only withdrawals, and thin liquidity outside major sports.

Best for: Casual traders who value funding convenience; New York residents (live there since June 2026, where Kalshi faces enforcement). Key scores: Regulation 8.5 | Deposits 8.0 | Liquidity 5.5

#4: ProphetX — Best for Serious Sports Traders (6.7 / 10)

ProphetX won dual CFTC approval (exchange + clearinghouse) in June 2026 and launched nationwide except Nevada a week later. It’s the most trader-shaped sports platform available: back or lay any outcome, set your own prices, and pay fees only when you profit — 2% of net winnings, 0% on parlays, nothing on losses. The iOS app rates 4.8★, the highest in the field.

It’s sports-only by design, liquidity thins beyond the major leagues, and deposits skip cards and PayPal entirely (bank via Aeropay, crypto, or wire).

Best for: Profitable sports traders — the fee structure is unbeatable if you win; exchange-style price setters. Key scores: Regulation 8.0 | Fees 8.0 | UX 8.0 | Markets 5.5

→ Read the full ProphetX review

#5: FanDuel Predicts — Easiest On-Ramp (6.4 / 10)

Seven months after its CME Group-backed launch, FanDuel Predicts is still the smoothest mainstream entry point: zero deposit fees on every method (including PayPal and Venmo, which nobody else offers), the friendliest interface, and financial markets nationwide with sports contracts in 18 non-sportsbook states including California, Texas, Florida, and Georgia.

The 2%-of-payout fee is consistently more expensive than Kalshi and Polymarket, there’s still no web platform, and while politics-labeled contracts began appearing in 2026, the category remains thin.

Best for: Beginners, existing FanDuel users, sports traders in non-sportsbook states. Key scores: Deposits 8.5 | Regulation 7.0 | Markets 5.5

→ Read the full FanDuel Predicts review

#6: Underdog Predict — Best In-App Convenience (6.3 / 10)

Underdog was the first fantasy operator to add CFTC-regulated event contracts (September 2025, via Crypto.com’s exchange), and in March 2026 it bought Aristotle Exchange — the CFTC-registered exchange previously owned by PredictIt’s parent — to eventually run its own. Flat ~2¢ contract fees, zero deposit/withdrawal fees, and a 2026 slate that added geopolitics, hurricane, and Fed markets to its sports core.

It’s a feature inside a fantasy app rather than a trading platform: Trustly-only withdrawals, 27-state footprint, and modest depth.

Best for: Underdog fantasy players — one tap, one wallet. Key scores: Regulation 7.5 | UX 7.0 | Liquidity 5.0

→ Read the full Underdog Predict review

#7: Fanatics Markets — Best Rewards (6.2 / 10)

Fanatics’ standalone prediction app routes to Crypto.com’s regulated exchange through its own CFTC-registered introducing broker. The slate is surprisingly broad — sports (including the official FIFA World Cup hub built with ADI Predictstreet), crypto, politics, and culture — and FanCash rewards pay up to 10% back on trades during the World Cup, win or lose.

Fees run higher than Kalshi’s at most prices (2.4¢ per contract, charged on both buys and sells), liquidity is thin, it’s 21+ in a 24-state footprint, and support is bot-only.

Best for: Fanatics ecosystem users and World Cup traders in non-sportsbook states. Key scores: Regulation 7.5 | Withdrawals 7.0 | Support 4.0

→ Read the full Fanatics Markets review

#8: Novig — Best Price, Least Protection (6.0 / 10)

Novig’s zero-commission peer-to-peer sports trading is genuinely the best pricing in the field, wrapped in a 4.7★ app. But today’s live product is still a sweepstakes — no federal fund protections — even though its exchange entity won CFTC designation on June 16, 2026. A regulated all-50-states launch is planned by end of summer, and this score gets rewritten when it ships.

Best for: Price-first sports traders in its 34 states who accept sweepstakes mechanics — or anyone waiting for the regulated launch. Key scores: Fees 8.5 | UX 8.0 | Regulation 4.5

→ Read the full Novig review

Not Yet Rated: ADI Predictstreet

The official prediction market partner of the FIFA World Cup 2026 launched June 8 with near real-time in-game settlement on soccer markets. Its US presence runs through the Fanatics Markets World Cup hub; the platform itself is Gibraltar-licensed with no US registration, and no verifiable fee schedule exists — so we’ve profiled it rather than scored it. Read the ADI Predictstreet profile.

Best Platform by Use Case

Best for Safety and Regulation

Winner: Kalshi (9.0/10) — its own CFTC exchange and clearinghouse with the longest operating record and a landmark 2024 federal court win. ProphetX and OG run the same dual structure with shorter track records; Polymarket US is close behind since going fully live.

Best for Low Fees

Winner: Polymarket (9.0/10) — near-zero global fees; US taker fees capped at 1.25¢/contract with maker rebates. For profitable sports traders: ProphetX — 2% of net winnings only, so losing trades cost nothing and parlays are free.

Best for Beginners

Winner: FanDuel Predicts — familiar brand, PayPal/Venmo funding, simplest interface. Kalshi remains the better platform to grow into. See our full beginners ranking.

Best for Politics and Elections

Winner: Kalshi — the deepest regulated US politics markets. Polymarket US now offers regulated politics access with better prices on overlapping markets; OG and Fanatics carry politics categories with thinner books.

Best for Sports

Winner: ProphetX for active traders (back/lay, fees on winnings only); Kalshi for breadth and liquidity where sports markets aren’t geofenced; FanDuel Predicts or Fanatics Markets for casual trading in CA/TX/FL/GA.

Best for Crypto Users

Winner: Polymarket (global platform) for non-US users — native USDC on Polygon. US residents wanting crypto funding: OG’s parent is Crypto.com, and Kalshi and ProphetX both accept crypto deposits via Zero Hash.

Best for International Users

Winner: Polymarket (global) — every other platform on this page is US-only.

How to Choose

1. What do you want to trade?

• Politics, economics, news → Kalshi or Polymarket US
• Sports, actively → ProphetX; sports, casually → FanDuel Predicts, OG, or Fanatics
• A bit of everything → Kalshi for regulated breadth, Polymarket for global breadth

2. How do you want to fund it?

• PayPal/Venmo → FanDuel Predicts or OG
• Bank transfer → any major platform; Kalshi and ProphetX are free via ACH
• Crypto → Polymarket (global), Kalshi, OG, or ProphetX

3. Where do you live? Sports-contract availability now varies meaningfully by state — check our legality checker before choosing a platform for sports trading.

Still unsure? Start with Kalshi — the widest selection, strongest regulatory record, and full web/mobile coverage. Add Polymarket US (if you’re on iOS) for better pricing on overlapping markets. There’s no exclusivity; most active traders hold multiple accounts.

What We’re Watching

• Novig’s regulated launch: zero-commission trading on a CFTC exchange in all 50 states, promised by end of summer 2026, would pressure every sports-focused platform.
• Polymarket’s Android/web rollout and its April 2026 filing to bring US users onto its global exchange — either would strengthen its #2 case.
• The state-vs-federal sports fight: the July 2026 New York ruling against Kalshi is headed for appeal; the CFTC’s proposed event-contract rulemaking (comments close August 2026) could redraw the map.
• Underdog’s native exchange: the Aristotle acquisition gives it its own CFTC registrations; a native launch would upgrade its regulatory score.
• Tax guidance: the IRS still hasn’t issued definitive prediction-market tax rules. Platforms with real documentation will gain an edge when it does.

We update scores when platforms make meaningful changes, with changelogs on each review page.

Common Questions

What is the best prediction market platform in 2026?

Kalshi, at 7.4/10 — the strongest combination of regulation, market breadth, and liquidity, validated by record June 2026 volume above $31 billion. Polymarket (7.1) is closing fast now that its US platform is fully open on iOS. The right answer varies by use case: see the use-case picks above.

Are prediction markets legal in the United States?

Yes, on CFTC-regulated platforms — that now covers seven of the nine platforms on this page. The contested territory is sports contracts, geofenced in roughly seven states with litigation ongoing. See our legal guide and state-by-state checker.

Which prediction market has the lowest fees?

Polymarket for most traders (near-zero global, capped 1.25¢/contract US). ProphetX for winning sports traders (2% of net profit only). Novig charges nothing but is sweepstakes-based today. Run your own numbers with our fee calculator.

How much money do you need to start?

$10 covers the minimum deposit on most platforms, and contracts cost under $1 each. $50–100 is a practical starting bankroll. See Your First Prediction Market Trade for a walkthrough.

Are prediction markets safe?

The regulated platforms hold customer funds under federal segregation rules — a real structural protection, though not FDIC insurance, and never a guarantee against trading losses. Sweepstakes products (Novig today) and offshore platforms (Polymarket global, ADI Predictstreet direct) carry meaningfully less protection. Details in each platform review.

What changed in 2026?

Almost everything: five new platforms launched or won CFTC approval, Polymarket opened fully in the US, the World Cup drove record volumes ($44.8B combined Kalshi+Polymarket in June), and the state-vs-federal legal fight over sports contracts escalated to criminal charges in Arizona and a New York enforcement ruling. This page’s March 2026 version compared three platforms; today it compares nine.
