Today
The session in one read.
Up to nine stories a session — the data print, the company move, the narrative that lifted a group — each told with its evidence, dated, ranked by how much it mattered. A quiet day stays short.

From the tape to the record
- 01
Detect
From the 4 a.m. pre-market to the 8 p.m. close, tracked movers and candidate names are re-checked every few minutes; through the regular session the market's biggest gainers, losers and most active names join the scan. A move has to be big for the company: 0.9% over $200B, 2.4% for a small-cap.
- 02
Attribute
Each move is matched to the news that preceded it — a filing, a data print, a headline — and the catalyst is published with its evidence cited and dated. When nothing qualifies, the move is published without a driver. No guess.
- 03
Connect
Moves that share a story become a theme: a narrative that moved several stocks at once, tracked round by round as it evolves, with the stocks it reaches and the evidence behind it.
- 04
Record
Every published story, move and theme is dated. Each attribution carries its cited evidence; a move with no established driver is labelled as such. When better evidence changes an attribution, its citations and its time are updated with it. That archive is what you read — and what your AI assistant can read too.
One kernel, five screens
Pulse
Every notable move, live.
The feed of moves as they are detected, each with its catalyst or an honest "no driver established". Filter by sector or direction; follow stocks and themes to see only yours.
Themes
The narratives behind the tape.
Cross-stock stories that link today's movers: what drove them, which way the members went, how the story has evolved round by round. A theme names the cause, never a sector label.
Stock pages
Every stock, in context.
Open one ticker and its sector, its narratives, its move history with each attribution, and the peers it has been co-narrated with come with it.
Market & Calendar
Indices, macro backdrop, breadth and the sector heatmap; the week's economic releases with actual, consensus, previous and an editorial importance tier, and the earnings lane with the companies scheduled and their prior moves.
Seven languages. iOS, Android and the browser.
MCP · FOR CLAUDE, CLAUDE CODE AND OTHER MCP CLIENTS
Your AI assistant, with a market memory.
A model re-derives today's market from today's headlines. Connect What's Moving and it reads the record instead: what moved, its dated and cited attribution, which narratives it joined and how they developed — fourteen read-only tools over the same archive the app shows. The archive grows every session. Ask about a chart and the daily bars arrive with up to six indicators already computed, in the same call.

assistant
One narrative matches, first recorded in August. Its history shows which members moved, when and which way; the moves it references carry the cited evidence. Every attribution is editorial and dated; nothing in the record says what happens next.

Publisher, not advisor
-
No predictions, no advice.
Everything here is commentary on events that already happened — never a recommendation to buy or sell, never personalised.
-
Evidence, or no driver named.
Every attribution is editorial, cites its source and shows when it was made. When better evidence changes an attribution, its citations and time are updated with it. When no fact qualifies, the move is published without a driver.
-
We link to our sources. Judge them before you rely on them.
What we cite comes from public sources: wires, official releases, data prints and the press. We judge whether a source supports an attribution, but we do not verify every fact it reports.
-
Your watchlist never shapes the content.
Personalisation is a filter on what you see — structurally separate from what gets written.

FAQ
Is this investment advice?
No. What's Moving is a publisher of general, impersonal commentary on market events that have already occurred. It never tells you what to buy or sell, and never predicts.
Why not just ask a chatbot?
Ask one why a stock moved and it reconstructs an answer from whatever it finds at that moment. What's Moving was watching when it happened. It recorded the move when it was detected, kept the evidence with its own source and time, and dated its editorial attribution. When nothing qualified, it named no driver. Ask again next month and the record is the same, or updated and dated. Your own AI assistant can read that record directly: see MCP.
What counts as a move?
US-listed common stocks at or above $2 that surface on the market's mover feeds — biggest gainers, losers and most active — with a bar that scales with size: 0.9% for a company over $200B, 1.5% over $10B, 2.4% below that. Funds, SPAC shells, warrants and units are filtered out.
Why is the free tier delayed?
Timeliness is what Pro pays for. Free and anonymous readers get every new story, move and theme 15 minutes after it publishes; an assistant on a free account sees the last 30 days. Nothing else is held back.
Which AI assistants work?
Claude and Claude Code are verified: add the endpoint and sign in. Other MCP clients that speak Streamable HTTP and can send a bearer-token header can use a personal access token minted in the app under Account → AI assistants — see /connect/. The server is read-only.
How do I cancel or delete my account?
Cancel in your App Store or Google Play subscription settings; access lasts through the paid period. Deleting the account in the app (Account → Manage account → Security) removes your profile, follows and AI access tokens; it does not cancel a store subscription. See Privacy for what is retained while deletion completes.
