Prediction markets
The BanterBubbles alternative for prediction markets
Love seeing markets as bubbles? PredictionBubbles brings the same visual immediacy to a different kind of market — questions about what happens next. Banter Bubbles visualizes assets and their prices; this board visualizes what markets believe.

See what prediction markets are watching
Every bubble represents a market question. Instead of the price of an asset, it shows the market's current probability for an event — size follows the selected board view (money traded by default), color is the probability.
This is the actual board, live — the embed carries its busiest 300 markets, and the full set with every control (view, sort, venue, category, search) is one click away. From markets to meaning: will it happen, when, how likely — and what changed today?

Why PredictionBubbles is different
Events, not assets
Banter Bubbles visualizes crypto and stock assets. Every bubble here is an event market: “Will Bitcoin reach X?”, “Will the Fed cut rates?”, “Will the bill pass?” — the question is the object, not the ticker.
Probabilities, not price moves
An asset bubble says “+4.2%”. A prediction bubble says “63%” — the price of a contract that pays $1 if the event happens, which reads as the market's implied probability. Implied, not oracular: the exact meaning always depends on the market's own resolution rules, and the pages say so.
Polymarket + Kalshi in one board
Two prediction venues share the picture, so the same question can be read — and compared — across both.
Opportunity discovery
The board ranks by more than size: opportunity score, 24-hour movement, activity, volume and open interest each answer “which markets deserve attention right now?” — and the sure-bet scanner flags linked markets whose prices disagree, every 15 minutes.
Live market signals
Follow any market for push alerts on 5+ point moves and fresh news, and fresh scanner findings post to the Telegram channel: t.me/predictionbubbles.
Prediction-market context
Every bubble opens into its own page — current odds, probability history, volume and open interest, related markets, headlines where available. From “something moved” to “here is why this market is interesting.”
The mental model
Asset bubbles ask
“What is moving?”
Bitcoin · Ethereum · Nvidia · Tesla — each bubble an asset, its price and its move.
Prediction bubbles ask
“What might happen?”
Will Adanech Abiebie be the next Prime Minister of Ethiopia?
0.5%implied probability
Each bubble a question, priced by people betting on the answer.

When BanterBubbles is the better choice
If you want to scan crypto or stock assets, compare price movements, watch volatility and follow asset-specific news, Banter Bubbles is built for exactly that use case. PredictionBubbles is a different instrument: it is built around prediction markets — questions about future events, their implied probabilities, and how those probabilities change. Different problem, different tool.
Questions the market is watching
Straight from the current export — one market from each of the board's biggest categories, with the numbers the board is showing right now. An asset tracker has no shelf for questions like these.

How PredictionBubbles works
Every 15 minutes the pipeline pulls the open markets from Polymarket and Kalshi, prices each one as a probability, and redraws the board. Bubbles are sized by the selected view — money traded by default — and colored by how likely the market says the event is. Click a bubble for the market's own page: odds history, depth, related markets. The same sweep feeds the sure-bet scanner and the Telegram feed.
Questions
What is the difference between BanterBubbles and PredictionBubbles?
Banter Bubbles visualizes asset markets — crypto and stocks — as bubbles sized and colored by price data. PredictionBubbles uses the same visual idea for prediction markets: each bubble is a real-world question, sized by money traded and colored by the market's implied probability.
Is PredictionBubbles a BanterBubbles replacement?
No. If you want to track asset prices, Banter Bubbles is built for that. PredictionBubbles answers a different question — what markets think will happen — and plenty of people will want both.
Does PredictionBubbles track crypto?
It tracks crypto event markets — questions like “Will Bitcoin reach X by December?” — not coin prices. The board has a Crypto category with every such market the venues carry.
Does PredictionBubbles track stocks?
Not stock prices. Where the venues run event markets about companies or the economy — earnings, rates, indices — those appear in the Finance category as questions with probabilities.
What are prediction-market probabilities?
A contract that pays $1 if an event happens trades at some price — say 63¢ — and that price reads as the market's implied probability of the event. It is the crowd's live estimate, not a forecast by this site, and it moves as people trade.
Where does PredictionBubbles get its data?
From Polymarket and Kalshi's public APIs. Prices are the venues' own — this site displays them and says which venue each number belongs to.
Is PredictionBubbles free?
Yes. The board, the market pages, the surebets scanner and the alerts are free, and none of it needs an account.
Is PredictionBubbles a betting site?
PredictionBubbles is an information tool. We display prices published by Polymarket and Kalshi. We do not accept wagers, hold funds, or offer accounts.
Can I embed PredictionBubbles?
Yes — the embed builder generates an iframe of the live board, filtered to whatever slice fits your page.
How often does PredictionBubbles update?
Prices refresh every 15 minutes, and an open board re-polls itself so a tab left open stays current.
