MarketCatalyst

What it is

MarketCatalyst is a browser terminal for US equities that answers one question per screen: what moved, and what the evidence for the move is. The features page lists 17 workspaces in five groups. Home holds a dashboard (tape, movers, earnings, heatmap) and a live news feed tagged to tickers. Markets holds the Earnings Hub (every report against consensus with the pre-market and after-hours reaction, guidance and a 10-quarter history), Movers (top 100 gainers and losers, unusual volume, weekly leaders, each with relative volume), a heatmap, Analyst Actions (upgrades, downgrades, initiations and price targets from 221 firms, with per-firm tallies) and Macro & VIX (economic calendar with estimate, actual and prior, VIX-sensitive stocks, market holidays). Research holds a screener with 20 presets and relative-strength, growth, technical-rating and liquidity filters, Themes, IPOs (performance against offer, the SEC pipeline, a calendar), Ownership (Form 4 insider trades and 13F holdings read from EDGAR), ETF Corner and AI Corner. Daily and weekly recaps, a portfolio and a watchlist round it out.

The AI layer is the pitch. "What Matters Now" is a rolling synthesis of the session, "Why It Moved" is a one-line explanation on hover for any ticker, and "AI Stock Read" summarises each stock page by trend, levels, strength and risk. The about page says the model writes over an in-house derived record and "does not forecast, it does not rank, and it does not recommend". Each stock page carries a candle chart with moving averages, volume and RSI; there is no charting workspace and charting is not what the product is bought for.

The publisher is MarketCatalyst Analytics LLC of Texas, per terms dated 22 October 2026. The domain was registered on 10 July 2026 and the Wayback Machine's first capture is from 14 October 2026. Nothing on the site names a founder, an address or a launch date.

Pricing

Three plans, all month-to-month, read from the home page on 27 October 2026:

• Starter, $0. All 17 workspaces on delayed market data and a daily end-of-day recap.
• Pro, $29 a month. Real-time data and alerts, the AI read in every view, portfolio and watchlist AI, scheduled recaps.
• Elite, $79 a month. Multiple portfolios and 13F tracking, custom alert rules, API access and data export, priority support.

No annual price is shown anywhere, and no trial is advertised; the terms say any trial, if offered, is one per customer per plan. Subscriptions auto-renew, cancellation takes effect at the end of the billing period, and there are no refunds for partial periods. Stripe is the processor.

The entry decision is simpler than the three columns suggest: on Starter the AI read exists only in the daily recap, so the $29 buys the product the marketing describes. The Elite step is for 13F tracking and the API.

Data & coverage

US equities, ETFs and index levels, with an options chain and IPO data. The terms say the service "is intended for users in the United States". Nothing on the site names a market-data provider: the terms attribute pricing, news, fundamental and analyst data to "third-party data providers, exchanges, public sources (such as SEC EDGAR)", and the privacy policy lists "market data providers" without naming them. Filings are the exception: Form 4 and 13F are read from EDGAR directly.

The delay on Starter is not stated in minutes. The terms say data "may be real-time, delayed, or end-of-day" depending on plan, that each panel labels itself live or end-of-day "where we can do so", and that "you should not assume any figure is real-time". Pro is sold as real-time; whether a professional-status attestation is required is left to the providers, which the terms say may ask.

The about page gives the history window as 10 reported quarters per name and 400 days of rolling retention under a published policy. Relative strength (a 1 to 99 rank), surprise and revision history, breadth and the technical ratings are computed in-house rather than taken from a vendor's scoring.

Integrations

A web app only, signed in with Google or email and password; no mobile app is mentioned. Recaps download as PDF with a 60-second audio version. Holdings are added by hand or by "Import from photo"; there is no broker connection. Alerts arrive at Pro, custom alert rules at Elite.

The API exists only on Elite and has no public documentation (the docs path returns 404). The terms limit it to "your own personal, internal research", forbid redistribution and any use in a public or commercial product, forbid using the data to train a model, and let the vendor change rate limits or withdraw endpoints at any time. Treat it as an export convenience, not a data feed. No MCP server, no spreadsheet add-in, no Python client.

Limitations

• The options chain may show made-up numbers. The FAQ says "some option figures are illustrative/simulated for demonstration" and the terms repeat it. Confirm any options price with a broker before acting on it.
• The product is weeks old and the vendor's own counts disagree. The features page says 17 workspaces, the FAQ footer says fourteen, and the vendor's submission to this catalogue said 16. Expect the surface to keep moving.
• No data provider is named, so there is no way to check exchange coverage, corporate-action handling or the delay on the free tier against a source.
• US only, by the vendor's own terms. No non-US listings, no futures, no forex, no crypto.
• The AI output carries its own disclaimer. The terms say it "may be inaccurate, incomplete, outdated, or misleading", and the model provider is not named.
• The terms say "not an alert service" while Pro sells alerts. The intent is clear enough (alerts are data notifications, not calls), but the terms also warn that alerts "may be delayed, fail to trigger, trigger in error".

Alternatives

For a research terminal with global coverage, financials and estimates, Koyfin is the established product at a higher entry price. Godel Terminal covers the same ground (earnings, analyst ratings, filings, holders, transcripts) through a Bloomberg-style command line and names its data sources. Finviz Elite is the screener and movers page without the AI layer, with CSV export. For the ownership workspace alone, Quiver Quantitative goes deeper into insider, congressional and 13F records, and the insider and 13F trackers category holds the rest.
