— Predictions Intelligence Service / N° 002

The predictions
knowledge base
for AI agents.

Evens is the data layer AI agents call when they need real-time prediction-market intelligence. Consensus prices across Kalshi and Polymarket, cross-venue arbitrage, whale signals, and topic-level synthesis. One MCP install. One source of truth.

Why now

Two market
conditions just changed.

01

AI agents are buying real-time data.

Tavily, Perplexity API, Exa, Linkup, Serper — each crossed $10M ARR selling "data for AI agents." Tavily alone runs ~100M monthly requests. None of them touch prediction markets.

02

MCP became the integration surface.

Claude Code, Cursor, Windsurf, ChatGPT Apps all consume MCP. Forrester predicts 30%+ of enterprise vendors ship MCPs in 2026. The only listed predictions-market MCP today has 29 generic tools and no positioning.

“Tavily owns horizontal web-search for agents. Evens owns the predictions vertical.”

Built & running

The infrastructure
already exists.

We've spent the past year building the canonical data layer underneath the rebrand. ~80% of the work for the agent product is repackaging what's already in production.

Canonical data model

75+ models normalising events, markets, references, prices across 4 venues.

Internal MCP server

70+ tools in production for sync, remap, template debugging.

REST + GraphQL + WebSocket

OpenAPI 3.1 documented. Live price feeds. Already used by paying customers.

Arbitrage scanner

Cross-venue spread detection with worked-payoff playbooks.

Whale tracker

Large-position detection across providers with size estimation.

Webhook + alert engine

Threshold rules with retry logic; ready to push signals to subscribers.

The wedge

One feature.
One install.
One brand line.

We're shipping a public, registered MCP server tuned for agent reasoning — not internal ops. Curated 10-tool surface, with one synthesis tool nobody else builds.

1

Read & signal tools

search_markets, find_arbitrage, recent_whale_trades, price_history. Reuses scanners already in production.

2

prediction_brief

Single-call synthesis. Topic in, full intelligence packet out. Today an agent needs ~5-7 separate calls to assemble this.

3

subscribe_alert

Agent registers a webhook for a price / arb / whale condition. Closes the loop — we push, they listen.

The killer tool is prediction_brief. Once an agent depends on its response shape, the response shape is itself a switching cost.

Defensibility

Four moats.
Compounding.

Distribution

Registered in the Anthropic MCP registry on day one. Every Claude Code, Cursor, and Windsurf user discovers Evens through claude mcp browse. First-mover lock-in on the install is structural.

Data flywheel

More agents calling = more usage signal on what queries matter = better-tuned synthesis = more agents calling. The same loop Tavily ran from $0 to $10M ARR in 18 months.

Multi-source synthesis

Polymarket / Kalshi will eventually ship single-venue MCPs. They can't ship cross-venue arbitrage, whale signals, or consensus pricing — that requires aggregator infrastructure.

Switching cost

Once an agent's prompts depend on prediction_brief's response shape, replacing the source means rewriting the agent. The response contract is itself the lock-in.

“What if Polymarket / Kalshi ship their own MCP?” They will — for their venue. Our moat is the multi-source layer they can't replicate.
