A night of fireworks over the AI stock market.
Bubble-Market shows the biggest AI-related US stocks as glowing cores in a night sky — around the clock, weekends included — priced from the perpetual contracts that track them on major crypto exchanges.
How to read it
- Size is market cap: the price shown × shares outstanding. Pre-IPO names use an approximate private valuation instead.
- Height is the move over the selected window — 1 hour, 24 hours, 1 week or 1 month — with 0 % at the middle of the sky and the legend on the left. Switching the window relaunches the show.
- Colour runs from green (up) to red (down), stronger the bigger the move. Winners bloom with sparks; losers rain embers.
- Shells at the bottom pick a view: the whole AI list, its divisions (chips, equipment, hyperscalers, infrastructure, software), other tech names, and pre-IPO perpetuals.
Where the prices come from
Each stock is priced from its perpetual contracts on several large crypto exchanges, combined into one indicative price weighted towards the most liquid venues. Perpetuals trade continuously, which is why the map moves when the stock market is closed — the contract then drifts on its own supply and demand while its reference index stays at the last close.
These are not share prices. They are derivative prices that normally stay close to the shares but can diverge, especially outside US market hours. Data refreshes every few minutes; the top-right corner says when it was last updated, and a banner appears if it is running late.
What-if tools
- Pop (needle) deflates a stock by the chosen percentage. Every other stock then moves by that shock times its correlation with the one you touched, computed from the last day of hourly prices. The page switches to a blue-and-orange scenario palette so it can never be mistaken for the market; “Scenario off” brings the live numbers back.
- Pump (manometer) inflates a stock by the chosen percentage, with the same correlated ripple through the others.
- Shake a stock to see only its most correlated names, lined up from the most positively correlated at the top to the most negatively at the bottom.
- Shift-click any stock, or use the pointer tool, for its detail panel: price, changes, a 30-day sparkline and the contract facts.
