Directional edgeProp desks and discretionary traders: what you can get, where, at size, and what a fair price says about the contract you quote.
RiskSportsbook trading and risk: your line against the exchange consensus, with the exchange's depth as the confidence.
Research and mediaResearch teams and publishers: one vendor for the sports and prediction-market layer, every number carrying its read time, with a coverage audit alongside the data.
Why StreetSpread

The record, and what we build on it.

SEVEN VENUES, AS QUOTEDONE RECORD

Cleaned, aggregated data

Seven venues read at the same instant, matched into one instrument with a stable identifier, fee-adjusted, the raw quote kept, and our own coverage audit alongside. Everything else here is built on this record.

One game on seven venues: each venue's price now against where it opened, with every sportsbook's hold

One id per bet

Seven venues read at the same instant and matched to one instrument: the exchanges' microprices beside each book's de-vigged line, its hold, and where each opened.

What an order fills at on Kalshi and on Polymarket as its size grows, net of each venue's fee

Cross-venue pricing and execution

The best venue after fees on every matched pair, the depth on both sides, and what an order actually fills at down the real ladder. A stale book is declined, never guessed.

The six busiest contracts on Kalshi and on Polymarket over 24 hours, each in the venue's own unit

Volume and flow

Volume from one minute to 24 hours in each venue's own unit, open interest, the hour's prints and the largest of them, and signed order flow from the venue's own tape. Kalshi reports contracts and Polymarket dollars; every row says which.

A contract charted four ways: candles with moving averages, MACD and RSI, then Heikin-Ashi, renko and point-and-figure

Charts

Any contract on any venue, in the bar style and indicator set you ask for, from 5-minute to daily bars, ticking live inside the AI chat.

One contract's factor card: its market-neutral move against the two-sigma flag, its Greeks, its loadings and the same bet on the other exchange

Factors and Greeks

One card per contract, the way it reads in the chat: beta, residual and a market-neutral rotation score flagged at two sigma; momentum, flow, liquidity and favourite loadings; delta, gamma, theta and vega adapted to binary contracts.

SSX, BLITZ and VOTE, hourly levels over a week

Indices

Nine category tickers rebased to 100 at inception: SSX across the exchanges; BLITZ, BASE, HOOP and ICE for the sports; VOTE, CHIP, SHOW and COIN for politics, tech, entertainment and crypto. Divisor and aggregate published, so every level can be replicated.

Snapshots observed on each venue against the one-a-minute expectation

The record

Our own coverage audit served next to the data, per venue, and a same-instant archive since April 2026 to replay any rule at the prices that were actually there.

The first panel is a diagram. Every chart under it is a read of the live board on Tue Oct 13, 2026, between 7:29 and 11:31 PM ET.
