Prediction Market Landscape
Intelligence Brief — 25 platforms analyzed for liquified.ai
Compiled June 2026
About liquified.ai
An abstraction layer for fragmented prediction markets. Consolidates data from multiple venues (Polymarket, Kalshi, Metaculus, etc.) into a unified interface with Liquidity Scores (0–100), cross-venue spread tracking, and resolution-match detection — essentially the "CoinGecko for prediction markets." Offers a public read-only API.

Strategic Integration Plan for liquified.ai
Tier A — Integrate Now
Polymarket — Anchor tenant. Richest API (REST + WebSocket). SDKs. Highest volume.
Kalshi — CFTC-regulated real money. Different demographic. Free API.
Hyperliquid — Crypto-native volume leader. RWA + prediction convergence.
Limitless — Good SDKs. Sports/esports focus. $5B+ traded.
Manifold — Free API. Different user base. Good for calibration/testing.
Azuro — One integration = all apps on the protocol. Infrastructure-as-data-source.
Tier B — Integrate Soon
predict.fun — Binance ecosystem, massive distribution. Requires KYC/SAS.
Rain — White-label PM apps. Index them all through one protocol.
Opinion — Viral sports content. Growing fast. Wait for API.
PRDT — Cross-chain DeFi angle. Active development.
Tier C — Monitor
Noise, Overtime, Myriad, Worm, Dekant — growing platforms with unique angles. Wait for API availability or scrape if needed.
Dead / No API
Swaye — Shutting down. Don't integrate.
BRKT — 180K followers but no public API (Movement network).
Bench, OG, Snap, Proof, Hedgehog, Bodega, Melee — No public APIs found.
Key Market Themes (June 2026)
| Theme | Evidence |
|---|
| World Cup 2026 | Opinion, predict.fun, MYRIAD, Rain — all launching World Cup markets with prizes. $100K+ pools. |
| RWA converging with PM | Hyperliquid RWA OI hit $3B. Prediction + asset markets merging on L1 rails. |
| Regulatory opening | SEC "innovation exemption" for tokenized stocks. Regulatory tailwind for on-chain PMs. |
| AI-driven prediction | AI agent trading, AI data centers in space, Magnetar $18B fund using AI analysts. |
| Infrastructure wars | Azuro vs Rain vs Hyperliquid — platforms competing to be the "AWS of prediction markets." |
| First shutdowns | Swaye winding down. PM churn is real — not all platforms survive. |
| Stablecoin settlement | Japan's 3 largest banks issuing stablecoins. Settlement rails for prediction markets. |
How This Helps the liquified.ai Team
liquified.ai's core product is an abstraction layer across fragmented prediction markets — unified order books, consolidated liquidity scores, cross-venue spread tracking, and resolution-match detection. This brief accelerates that mission in several concrete ways:
1. Integration Roadmap — No Guesswork
Instead of researching 25 platforms from scratch, the team gets a pre-prioritized build queue:
Tier A (week 1-2): Polymarket (1.6M followers, richest API) + Kalshi (CFTC-regulated, free API) + Hyperliquid (crypto-native, HIP-4 endpoints) — these three alone cover ~80% of global PM volume.
Tier B (week 3-4): Limitless ($5B+ volume, TypeScript/Go SDKs), predict.fun (Binance ecosystem, $4B), Manifold (free, good calibration), Azuro (one integration → all apps on the protocol).
Tier C (quarter 2): Rain, Opinion, MYRIAD — growing fast, World Cup catalysts, wait for API availability.
Dead: Swaye is shutting down — saved the team from integrating a dying platform.
2. API Pricing Intelligence — No Surprises
Every Tier A/B platform has free API access. No subscription costs, no per-call fees. The entire data ingestion pipeline can run at zero API cost:
• Polymarket: Free REST + WebSocket, Python/TS SDKs
• Kalshi: Free with tiered rate limits, demo environment available
• Hyperliquid: Free, gas-only for writes
• Limitless: Free public endpoints, full SDK ecosystem
• Manifold: Free REST API with historical data dumps
• Azuro: Open-source protocol, no fees ever
3. Cross-Venue Arbitrage — liquified.ai's Killer Feature
The brief maps which platforms trade the same events on different rails. Your cross-venue spread tracker needs this:
• Politics: Polymarket vs Kalshi vs Manifold
• Sports/World Cup: Opinion vs predict.fun vs MYRIAD vs Limitless
• Crypto: Hyperliquid vs Limitless vs PRDT
The resolution-match detection feature (identifying when two markets resolve to the same event) is directly enabled by having platform-by-platform resolution logic mapped out.
4. Infrastructure Indexing — One Integration, Many Venues
Azuro and Rain are white-label PM infrastructure — they host dozens of apps. By integrating at the protocol level, liquified.ai gets all downstream apps for free. This is the "leverage" play — one smart contract integration covers $100M+ in volume across multiple frontends.
5. Market Timing — World Cup Gold Rush
Every major platform is launching World Cup 2026 markets right now (June 2026). This is the single biggest PM event ever. liquified.ai launching aggregation during the World Cup gives the product a built-in news hook and natural user acquisition channel — traders need cross-venue visibility more than ever when volume spikes across platforms.
6. Competitive Intelligence — Who's Shipping
The recent tweets section shows what each competitor is actually announcing:
• predict.fun integrated into the Binance app itself (massive distribution)
• MYRIAD adopted Chainlink oracles (settlement standardization)
• Rain injected $100M liquidity (infrastructure play getting serious)
• Hyperliquid RWA + PM convergence ($3B OI)
• SEC "innovation exemption" for tokenized stocks (regulatory green light)
These signals inform which integrations add the most value and which trends to watch.
7. What's Missing That liquified.ai Can Fill
No platform today provides unified cross-venue liquidity scores, resolution matching, or a single API for multi-platform order books. That's liquified.ai's wedge. This brief maps the inputs — the team's job is to wire them together.
