On Nimb, every Polymarket market belongs to one of seven categories: Geopolitics, Politics, Finance, Crypto, AI & Tech, Sports, and Climate & Culture. The category sets the circle's colour and where it sits on the map, and you can show one or several categories at a time.
A category is the broad subject area Nimb assigns to a market, shown as its colour on the map. Categories are the coarsest layer of market reading on the map: they tell you where the money is going across subjects before you look at any single market. Finer groupings are themes.
Which categories does Nimb use?
| Category | Colour | Typical markets | Share of 7D volume |
|---|---|---|---|
| Geopolitics | Red #E9473A | Wars and ceasefires, Iran, Israel and Gaza, Russia–Ukraine, foreign leaders | 23% |
| Politics | Blue #4C8DEB | Elections and nominations, US Congress and courts, elections abroad | 37% |
| Finance | Yellow #F2C431 | Fed decisions, rates, inflation, stocks and indices, IPOs, gold, silver and oil | 16% |
| Crypto | Orange #F2892E | Bitcoin and Ethereum prices, altcoins, token launches, crypto regulation | 6% |
| AI & Tech | Green #3FAF76 | Model releases and rankings, AI companies, big tech | 1% |
| Sports | Khaki #A9A383 | Football, US leagues, esports, tournaments and awards | 16% |
| Climate & Culture | Purple #9B7FE6 | Temperature and weather records, film and TV, music, awards, public health | 1% |
Shares are of the volume traded over 7 days by the 110 markets on the 7D map, from the snapshot of 2026-11-07 13:00 UTC, rounded; they shift with every data run. For current examples of each category, browse the market pages.
How is a market assigned a category?
Nimb starts from the tags Polymarket puts on each event, then corrects the cases where tags mislead:
- Tags first. Each event's Polymarket tags map to one category, checked in a fixed order: Crypto, AI & Tech, Geopolitics, Sports, Politics, Finance, Climate & Culture.
- Finance tags win over the others. If an event carries finance tags (stocks, commodities, gold, oil, the Fed, IPOs, economy) and no crypto tags, it goes to Finance.
- Titles break the remaining ties. If the title names a financial asset or indicator (gold, silver, WTI, Brent, NVDA, the S&P 500, Nasdaq, Treasury yields, the Fed, CPI, GDP) and no crypto asset, it goes to Finance; if it names a crypto asset and no financial one, it goes to Crypto.
Each market gets exactly one category. A market that spans two subjects, such as an election in a country at war, goes where its tags and title point first.
Why is gold under Finance, not Crypto?
Gold is a commodity, so it belongs with the other financial markets. Under the original rule, the tag order sent gold, silver, WTI oil, NVDA and S&P 500 markets to Crypto, because some of them carry tags (such as price-target tags) that the Crypto check matched first. Nimb's own tests flagged this, and the rule above (finance tags and asset names win unless a crypto asset is named) now puts them under Finance. A market such as "Will Bitcoin outperform gold?" would name both, and keeps the category its tags give it.
How many markets per category are shown?
Each timeframe shows 110 markets. Each category gets room in proportion to the money traded on its undecided outcomes, with at least 4 markets and at most 40% of the map, that is 44 markets. The floor keeps small categories visible; the cap stops one busy category from crowding out the rest. Selection runs for 24H, 7D and 30D; the shorter views reuse those lists (1H and 12H show the 24H selection, 3D the 7D one).
| Category | 24H | 7D | 30D |
|---|---|---|---|
| Geopolitics | 15 | 19 | 27 |
| Politics | 20 | 19 | 15 |
| Finance | 15 | 20 | 25 |
| Crypto | 12 | 7 | 10 |
| AI & Tech | 6 | 6 | 6 |
| Sports | 33 | 33 | 21 |
| Climate & Culture | 9 | 6 | 6 |
| Total | 110 | 110 | 110 |
Counts from the snapshot of 2026-11-07. Because of the floor, small categories such as AI & Tech get more places than their volume alone would give them. That is a choice for discovery, not a statement that they matter more. Selection rules are in market selection.
Can I filter by category?
Yes. Open "Categories" in the dock at the bottom of the map. Clicking a category while all are shown keeps only that one; clicking others adds them; clicking a shown category removes it. "All" brings back every category. Choosing categories resets the theme filter, and the themes list then shows only themes with markets in the categories you chose. The Nimb logo in the search bar also clears every filter. On the plain-HTML pages, /markets lists markets with their category.
What can categories not tell you?
A category is a label for browsing. Two markets in the same category can have nothing to do with each other, and markets in different categories can depend on the same event: a Fed decision is Finance, and its effect on Bitcoin is Crypto. For links between markets, see themes and factors. For the basics of what these markets are, see what are prediction markets.
From reading to execution
Use categories to narrow the map, then open a market and read it in the panel before you use the order ticket. More on the map's other layers in how to read the Nimb map.
