Live crypto market heatmap: treemap, sector grouping, real-time updates.

Token size on the heatmap is proportional to market capitalization. Bitcoin and Ethereum occupy the largest rectangles because they have the highest market caps. Smaller-cap tokens appear as smaller rectangles within their sector groupings. This sizing matches each token's visual weight to its economic significance, so the heatmap emphasizes the assets that move the most aggregate capital.

Green indicates positive price performance and red indicates negative price performance over the selected timeframe. Color intensity scales with the magnitude of the move: deep green for strong gains (above 5%), light green for modest gains, deep red for steep losses, and light red for modest declines. Neutral gray or very light colors indicate minimal price change. This color gradient makes extreme movers immediately visible across hundreds of tokens.

The Market Heatmap supports 1-hour, 24-hour, 7-day, and 30-day performance timeframes. Each timeframe recolors every token based on its price change over that period. Comparing the 1h and 7d views often reveals useful divergences: a token that is red on the 1h but deep green on the 7d may be experiencing a healthy pullback within a strong trend, while a token green on 1h but red on 7d may be a dead cat bounce.

The Market Heatmap refreshes with near-real-time price data, updating every few seconds. Market cap sizes and performance colors adjust continuously as prices change. During volatile market events, you can watch the heatmap shift in real time as sectors and tokens move, which gives you an immediate visual feed of market-wide price action that tables and charts cannot match.

Tokens are grouped by sectors including DeFi, Layer 1, Layer 2, AI, Gaming, Memes, NFTs, RWA, DePIN, Privacy, Oracles, CEX tokens, DEX tokens, and more. Sector boundaries are drawn on the treemap so you can visually distinguish sector-level performance at a glance. When an entire sector cluster shifts to deep green or red simultaneously, it signals broad-based sector rotation rather than isolated token moves.

The heatmap provides instant visual pattern recognition that tables cannot match. It reveals sector rotation (which sectors are gaining while others fade), relative strength (which tokens within a sector are leading versus lagging), and market breadth (whether gains are concentrated in a few names or broadly distributed). These patterns help identify where capital is flowing and which market themes have genuine momentum behind them.

Yes. The Market Heatmap is available free on Sharpe Terminal with no account required. All timeframes, sector groupings, interactive drill-downs, and real-time updates are accessible immediately. Heatmap data is also available through Sharpe's REST API, MCP server, and CLI tool for programmatic access.

Crypto market cap is calculated as current price multiplied by circulating supply, the number of tokens actually in public circulation, excluding locked, burned, or unvested tokens. For example, Bitcoin's market cap = BTC price x ~19.7M circulating BTC. Market cap does not account for illiquid tokens, so it can overstate true tradeable value for assets with shallow order books. It is the most widely used metric for ranking crypto assets by size and the basis for sector indexing and dominance calculations.

Circulating supply is the number of tokens currently available to the public and tradeable on exchanges. Max supply is the hard cap on how many tokens will ever exist: Bitcoin's max supply is 21 million, Ethereum has no hard cap, and most altcoins publish a fixed or inflationary schedule. Total supply sits between the two: all tokens that exist today including locked, staked, and team allocations. The ratio of circulating to max supply indicates future dilution, so a token with 20% circulating and 100% max supply will see 5x potential sell pressure as remaining supply unlocks.

A treemap is a data visualization that represents hierarchical data as nested rectangles, where each rectangle's area is proportional to a numerical value. In crypto market heatmaps, each token is a rectangle sized by market cap and colored by performance, with rectangles grouped by sector. A treemap shows market-wide patterns in one view: which sectors dominate capital, which tokens are biggest, and which are moving hardest. Treemaps are preferred over pie charts when comparing hundreds of items simultaneously because rectangles pack more efficiently than slices.

Use a heatmap when you want to read the whole market at once: sector rotation, breadth, relative strength, extreme movers. Use a sortable table when you need to rank, filter, or export a specific list of tokens by a specific metric. They pair well: scan the heatmap to see where capital is flowing, then switch to a sortable view to drill into the tokens or sectors that stood out. Sharpe's Market Heatmap and Market Cap rankings cover both.

Basic market heatmaps are fine for casual reference but thin on sector analysis and programmatic access. Sharpe's heatmap adds explicit sector groupings, 4 timeframes, interactive drill-down into token details, real-time updates, and a free API, MCP server, and CLI. It also cross-links into the rest of Sharpe: click a sector cluster to open the full Sector Tracker, or click a token to open that coin's Futures page.
