DeepNewz vs
SimpleFunctions.
DeepNewz is a news reader that surfaces prediction-market odds alongside personalised stories — a human-facing product for following events. SimpleFunctions is the agent layer underneath: causal-tree thesis decomposition with auto-evaluation heartbeats, autonomous trading with a 7-gate risk cascade, computed indicators across 48K contracts, and a 56-tool MCP server that lets any AI agent trade, reason, and calibrate against live prediction markets.

Verdict
Pick the one that fits how
you actually work.
Choose SimpleFunctions if
You are building agents, autonomous trading systems, or research pipelines — not a news feed. SimpleFunctions gives you calibrated world-model prices with public Brier scores, a causal-tree thesis system that auto-evaluates against live market signals, computed indicators (implied yield, cliff risk, liquidity availability score) across the full 48K-contract universe, Portfolio Autopilot with a 1M-context LLM and 7-gate risk cascade, and a 56-tool MCP server that drops into Claude Code or Cursor in one line.
Choose DeepNewz if
You want a consumer news experience where prediction-market odds are surfaced inline with relevant stories. DeepNewz is built specifically for that use case: a personalised AI news reader that contextualises each story with real-time market probabilities, designed for human readers rather than programmatic or agent clients.
DeepNewz pairs news stories with prediction-market odds for human readers. SimpleFunctions ships the agent layer: world model, theses, indicators, autopilot, MCP.
At a glance
Three things that
actually differ.
Everything DeepNewz gives you — prediction-market odds tied to real-world events on Kalshi and Polymarket — SimpleFunctions also gives you, on the same venues, via a normalised API across 48K+ active contracts.
On top of that, SF ships a causal-tree thesis system, an autonomous trading agent (Portfolio Autopilot, 1M-context LLM, 7-gate risk cascade), and 56 MCP tools that no current prediction-market news product exposes.
SF publishes live Brier scores at /api/calibration — Kalshi 0.20, Polymarket 0.12 on T-24h price, past 90 days — so you can audit SF's own accuracy programmatically, not just read it.

Methodology
Verified 2026-04 from public sources only — DeepNewz's documentation, public website, and publicly observable behaviour. We never claim non-public information about DeepNewz's internals. SimpleFunctions claims on this page are computed live from /api/calibration, /api/public/cross-venue/pairs, and /api/public/markets — you can re-verify them yourself with curl.
Use cases
Same data, different
best fit per scenario.
Scenario 01
An AI agent needs to monitor prediction-market probabilities and execute trades based on a structured causal thesis.
SimpleFunctions · best fit
SF is the native surface: POST /api/thesis/create decomposes the thesis into testable sub-claims, maps each to live contracts on Kalshi and Polymarket, and runs continuous evaluation heartbeats. Portfolio Autopilot can execute when conviction thresholds are met.
DeepNewz
DeepNewz is a human news reader and does not expose a programmatic API or agent interface.
Scenario 02
A retail reader wants to follow breaking news and immediately see what prediction markets are pricing for related outcomes.
SimpleFunctions
SF has no curated news reader UI; it exposes raw API endpoints and a CLI designed for programmatic access, not casual reading.
DeepNewz · best fit
DeepNewz is purpose-built for this: a personalised AI news feed with real-time prediction-market odds embedded per story, designed for human readers who want market context without querying an API.
Scenario 03
A researcher wants to compute implied yields and liquidity scores across the full prediction-market universe to find mispriced contracts.
SimpleFunctions · best fit
SF pre-computes implied yield (IY), cliff risk index (CRI), liquidity availability score (LAS), and event overround (EE) across 48K+ active contracts, accessible at /screen or via the MCP server.
DeepNewz
DeepNewz surfaces odds for newsworthy events but does not expose derived indicators or support bulk programmatic screening.
Scenario 04
A developer is integrating prediction-market context into a Claude Code or Cursor workflow via MCP.
SimpleFunctions · best fit
One line installs the full SF MCP server: `claude mcp add simplefunctions --url https://simplefunctions.dev/api/mcp/mcp`. All 56 tools — prices, thesis creation, orderbook, calibration — are immediately available in the agent context.
DeepNewz
DeepNewz has no MCP server; programmatic integration is not a documented use case.
Live data
The SimpleFunctions claims on this page are not marketing copy. Brier scores, market counts, and cross-venue pair counts are computed live from /calibration, /screen, and /api/public/cross-venue/pairs. All public, all free, all CC-BY-4.0.
FAQ
Does SimpleFunctions have a news feed like DeepNewz?+
No. SF does not have a curated human news reader. What SF does have is a thesis evaluation heartbeat that scans news as one of its signal sources when evaluating whether a thesis should update its confidence. That is a programmatic signal input, not a consumer news product. If you want to read news with prediction-market odds attached in a readable UI, DeepNewz is the right surface.
How does SF's causal thesis system work?+
POST /api/thesis/create takes a plain-language sentence and decomposes it into a causal tree of testable sub-claims. Each sub-claim is mapped to live contracts on Kalshi and Polymarket. An evaluation heartbeat then runs on a continuous cycle: news scan, price refresh, milestone check, LLM evaluation, confidence update. You can inject external signals via /api/thesis/{id}/signal. Public theses are forkable. No other prediction-market product exposes this.
What is Portfolio Autopilot and how does it differ from a news-based alert?+
Portfolio Autopilot is SF's autonomous trading agent. It uses a 1M-context LLM, draws on 13 data sources, and runs a 7-gate risk cascade — including a kill switch, position limits, drawdown gate, and regime check — before any order is placed. A news-based alert tells you something happened; Autopilot decides probabilistically whether that event warrants a trade and executes if gates pass.
Does DeepNewz have a public REST API?+
Based on publicly available information, DeepNewz does not document a public REST API. Its product is a consumer web and app interface for reading news. If you need programmatic access to prediction-market data, SF exposes a full REST API with an openapi.json spec, a 60-command CLI, and a 56-tool MCP server, with read operations requiring no authentication.
How does SimpleFunctions handle calibration and accuracy transparency?+
SF publishes its own Brier scores at /api/calibration, broken down by venue, category, and price bucket, refreshed continuously. Current figures: Kalshi 0.20, Polymarket 0.12 on T-24h price over the past 90 days. These are live numbers you can re-verify yourself with a single curl call. Most prediction-market data products claim accuracy without publishing a verifiable, queryable baseline.
What does 'agent-first' mean in practice for SimpleFunctions?+
SF is designed for AI agents as the primary consumer, not human dashboards. Concretely: a /.well-known/ai-world-state endpoint, an llms.txt and skill.md for LLM crawlers, an /api/agent/world snapshot (~800 tokens) with a delta endpoint for efficient context injection, a 56-tool MCP server compatible with Claude Code and Cursor, and an openapi.json for automated tool discovery. A human can use SF, but every surface is optimised for programmatic and agent access.
Can I use SimpleFunctions without writing code?+
Yes, via the CLI: `npm i -g @spfunctions/cli` gives you 60+ commands for prices, screening, thesis management, and orderbook queries. You can also add the MCP server to Claude Code or Cursor in one line and interact conversationally. The /screen page surfaces pre-computed indicators visually. That said, SF's core design is agent-first; if you want an integrated news-reading experience with market odds, DeepNewz is better suited.
