Best Prediction Markets in December 2025

Tagos is a next-generation prediction market that combines decentralized, on-chain trading with AI-powered forecasting tools — a combination that no other platform on this list offers. Built on a transparent blockchain architecture (primarily Arbitrum and Polygon), Tagos allows users to trade yes/no contracts on real-world outcomes spanning politics, financial markets, sports, and geopolitical events, with no platform trading fee beyond network gas costs.

The AI layer is Tagos's genuine differentiator. The platform integrates GPT-based crowd intelligence models that synthesise historical resolution data, market sentiment, and user performance records into probability estimates. These are displayed alongside market prices, giving traders a reference point beyond raw order book depth. User accuracy is tracked publicly across a leaderboard system, and strong historical performance earns reputation scores that influence position sizing access.

Account setup requires a Web3 wallet (MetaMask, Rabby, or WalletConnect-compatible) and USDC funding. There is no direct fiat on-ramp on the platform itself, though third-party on-ramp providers can be used to convert local currency to USDC. For users in Southeast Asia, this typically means buying USDC on a local exchange (Binance, OKX) and bridging or transferring to the Tagos wallet address.

Fees are genuinely low — network gas on Polygon is a fraction of a cent per trade, and gas on Arbitrum is similarly cheap. There are no platform trading fees, no withdrawal fees, and no deposit fees. Revenue is generated through liquidity mining incentives and a small percentage of protocol-level activity rather than user-facing charges.

The mobile experience is well-optimised for a Web3 application, with a responsive design that handles order entry, position tracking, and leaderboard views clearly on smaller screens. The referral programme and community XP rewards give active traders additional incentive to engage beyond pure P&L.

Tagos is the strongest choice for globally-connected, crypto-native traders who want uncensored access to prediction markets without geographic restrictions. US availability is in beta rollout. For traders in Vietnam, Indonesia, and the Philippines — where decentralised finance tools are widely used — Tagos is the most accessible and technically sophisticated option.

Polymarket is the largest decentralised prediction market in the world by trading volume, having processed over $18 billion in cumulative volume through 2024 and 2025. Built on Polygon — a low-cost Ethereum Layer 2 — Polymarket allows users anywhere in the world to trade USDC-denominated yes/no contracts on thousands of real-world events, from elections and central bank decisions to crypto price milestones and sports outcomes.

The platform is non-custodial by design. Trades are executed entirely on-chain, positions are held in smart contracts rather than with a counterparty, and market outcomes are resolved through a decentralised oracle system (UMA protocol). This means Polymarket has no ability to freeze user funds or manipulate outcomes — a structural guarantee that regulated platforms cannot match.

For users in Southeast Asia, Polymarket is highly accessible. There is no geographic restriction for non-US users, and funding requires only USDC and a Web3 wallet. USDC can be purchased on major exchanges (Binance, OKX, MEXC) available in Vietnam, Indonesia, and the Philippines, then transferred directly to a Polygon wallet address. Gas costs on Polygon are typically under $0.01 per transaction.

Market selection is the deepest of any platform on this list — thousands of active markets at any given time, including many that are unavailable on regulated US exchanges due to regulatory scope limitations. Popular categories include US and global elections, Federal Reserve rate decisions, cryptocurrency prices, sports championships, and geopolitical events.

Liquidity on top-tier markets (US elections, major crypto events) routinely reaches millions of dollars per market, with tight spreads between bid and ask prices. On smaller or more exotic markets, liquidity can be thin, and execution on larger position sizes may require patience.

The one limitation for US residents has historically been geographic restriction, though a CFTC-approved channel began expanding US access in late 2025 through a regulated partner. For everyone outside the US, Polymarket remains fully open and is the default choice for serious prediction market traders.

Kalshi is the first and most established CFTC-regulated event contract exchange in the United States. Founded in 2020 and licensed by the Commodity Futures Trading Commission, Kalshi occupies a unique legal position: it is the only platform that can offer event contracts on a regulated basis to US residents across all 50 states, including financial and economic outcome markets that are unavailable anywhere else in a legally compliant form.

The platform operates on a simple binary structure: users buy Yes or No contracts priced between $0 and $1 (or $0 to $100 in some markets), with the winning side receiving $1 (or $100) per contract at resolution. USD funding is direct — ACH bank transfer, wire, or debit card — with no crypto required. This makes Kalshi the most accessible prediction market for users who want to keep their trading entirely in traditional finance infrastructure.

Market categories include Federal Reserve interest rate decisions, employment reports, inflation data, GDP growth, electoral outcomes (subject to regulatory approval), and select sports markets. The regulated status means Kalshi cannot list some markets that Polymarket and Tagos offer freely — political betting markets, for example, have faced regulatory review — but the markets that are available benefit from high institutional participation and deep liquidity.

The trading interface is the most sophisticated of any prediction market platform: order books with visible bid/ask depth, price history charts, volatility indicators, and market research pages. Idle uninvested cash earns interest. The mobile app is polished and fully featured.

KYC requirements are strict — government-issued ID plus Social Security Number for US residents, full identity verification for non-US users. Kalshi is technically available to non-US users in supported jurisdictions, but the primary product is designed for and most useful to US residents with USD bank accounts.

For Southeast Asian users, Kalshi is the least relevant platform on this list due to the USD-banking requirement and US-centric market focus. It remains the benchmark for what regulated prediction markets can look like, and is the best choice for any US-based trader who wants a legally compliant, fully regulated experience.

Robinhood entered the prediction markets space in 2024–2025 by integrating event contracts directly into its existing brokerage app — the same platform used by over 20 million US retail investors for stocks, ETFs, and crypto trading. The event contract product is powered by Kalshi on the backend, meaning the actual market infrastructure, liquidity, and resolution are Kalshi's, while Robinhood provides the front-end wrapper and funding integration.

The core value proposition is convenience. Users who already hold a Robinhood brokerage account can trade prediction market contracts without setting up a separate account, completing additional KYC, or moving funds to a new platform. Positions in event contracts sit alongside stock and crypto positions in a single portfolio view. Funding draws from the existing brokerage cash balance.

Market access mirrors Kalshi's catalogue — economics, finance, and select sports outcomes — since Robinhood is reselling Kalshi's listed contracts. The key trade-off is fee structure: Robinhood adds approximately a 2x markup on fees versus trading the same markets directly on Kalshi. For occasional traders, this is negligible. For active traders or those with large position sizes, the fee differential adds up meaningfully over time.

The interface is deliberately simplified relative to Kalshi's full order book view. Robinhood presents binary outcomes as a simple buy/sell toggle without deep order book data or charting tools. This reduces complexity for new users but removes the analytical tools that experienced prediction market traders rely on.

Robinhood event contracts are available to US residents only, subject to the same state-level availability as Kalshi's product. The platform's existing user base makes it a natural entry point for retail investors curious about event contracts who do not want to research and sign up for a separate prediction market platform.

For prediction market traders outside the US — including Southeast Asia — Robinhood is not available. For US-based beginners specifically, it remains the lowest-friction way to start with prediction markets if you already have a Robinhood account.

Crypto.com is one of the largest cryptocurrency exchanges globally, with over 100 million registered users across more than 90 countries. Its entry into CFTC-regulated event contracts in late 2024 through its US partner CDNA (Crypto.com Derivatives North America) extended its platform into the prediction market space for US users, offering sports, politics, and economics markets within the familiar Crypto.com app ecosystem.

The product operates as a licensed event contract exchange within the US regulatory framework. Market categories at launch included US sports (NFL, NBA, MLB), political events, and macro-economic outcomes. Crypto.com also provides exchange backend infrastructure and liquidity to partner platforms — Fanatics Markets and Underdog both use Crypto.com's regulated exchange infrastructure — making it a significant behind-the-scenes player beyond just its consumer-facing product.

For existing Crypto.com users, the integration is seamless. Event contracts appear in the same app as spot trading, staking, and the Crypto.com Visa card. Deposits can be made via bank transfer, card, or existing crypto holdings, with automatic conversion at deposit time. This is the most connected prediction market experience for crypto-native users who already manage their digital assets on Crypto.com.

The fee structure is competitive at approximately $0.02 per contract (in line with Kalshi). Funding via crypto is supported alongside traditional fiat methods, giving it a broader appeal than purely USD-based platforms. The $50 sign-up bonus in CRO tokens provides a modest incentive for new users.

Availability for the US-regulated event contract product is restricted by state — New York and several other states are excluded. Non-US users of Crypto.com can access the broader exchange but not the CFTC-regulated event contract markets specifically.

For traders in Southeast Asia, Crypto.com's standard exchange products (crypto spot, staking, card) are accessible, but the prediction market event contracts are US-regulated and geographically restricted. Global prediction market access for SEA users remains better served by Polymarket and Tagos.

Fanatics Markets is a CFTC-compliant event contract platform launched in December 2025 by Fanatics — the largest sports merchandise and sports betting company in the United States, with an existing customer base of over 100 million sports fans. The prediction market product represents Fanatics' push into the regulated financial events space, leveraging Crypto.com's regulated exchange backend for market infrastructure and liquidity.

The platform launched on iOS and Android simultaneously, with an initial focus on sports markets — NFL, NBA, college football — alongside select finance and politics categories. Fanatics Markets is available in 24 US states, including major markets like California, Texas, and Florida. Importantly, it is available in states where traditional sports betting is illegal, since event contracts under CFTC regulation occupy a different legal category to state-licensed sports wagering.

The target user is a sports fan who wants to express an opinion on game outcomes, player performance, or championship results using financial contracts rather than traditional bets. The interface is built for this audience — simplified, visually engaging, and sports-first in its information hierarchy. There is no order book view or advanced charting; the focus is on accessibility for users who may have no prior trading experience.

Age restrictions are stricter than most platforms at 21 and older, which is unusual for a CFTC-regulated exchange (most require 18+). The rationale appears to align with Fanatics' existing sports betting products. No sign-up bonus or referral programme was available at launch, which is a notable gap given that competitor platforms like Kalshi and Crypto.com both offer welcome incentives.

As a December 2025 launch, Fanatics Markets has a very short operating history. Liquidity is building, customer support processes are new, and the market category range is still expanding. Users comfortable with limited track record in exchange for the Fanatics brand's mainstream credibility may find it an appealing on-ramp.

For users outside the US — including Southeast Asia — Fanatics Markets is not available. It is a US-only product.

Underdog Fantasy is one of the most popular daily fantasy sports apps in the United States, with a user base built on its Best Ball NFL product and pick'em style fantasy contests. In 2024–2025, Underdog expanded into CFTC-regulated prediction markets, offering sports-focused event contracts within its existing app — positioning itself as a destination for sports fans who want to graduate from fantasy contests to financial event contracts on real outcomes.

The prediction market product runs on the same Crypto.com regulated exchange infrastructure used by Fanatics Markets, meaning the underlying market structure, liquidity pools, and settlement processes are shared across both platforms. Underdog's differentiation lies in its existing sports community: millions of users who already engage deeply with game-by-game player performance statistics and have formed habits around the app's daily fantasy interface.

Market categories at launch focused on sports — primarily NFL, NBA, and college football outcomes — with limited initial coverage of non-sports markets. The interface mirrors the clean, visually-driven style that made Underdog successful in fantasy: outcome cards with probability meters, simplified yes/no positioning, and position tracking in a familiar format. There is no professional-grade order book or analytical tooling.

Fees align with the underlying exchange structure at approximately $0.02 per contract. Funding is via standard ACH bank transfer or debit card — no crypto funding option at launch. Withdrawals process via standard ACH timelines.

Underdog's prediction markets are available in a subset of US states. State-level availability depends on CFTC regulatory status and local financial product rules — not the same map as sports betting availability, since these are categorised as financial contracts rather than sports wagers. The 18+ age requirement is standard for financial products.

For traders in Southeast Asia, Underdog is not accessible — it is a US-only product built specifically for the domestic sports fantasy and prediction market audience. Global prediction market access remains better served by Polymarket and Tagos, both of which have no geographic restrictions outside the US.
