We just shipped a standalone CLI for PMXT.
Query, trade, and stream prediction markets from your terminal. Polymarket, Kalshi, Limitless -- one interface.

We've temporarily paused parquet file uploads to archive.pmxt.dev while we sort out an issue. Uploads will resume soon, and we'll backfill anything we missed.

Built with PMXT ๐ฅ
Built a tiny CLI for scanning prediction-market spreads.
It uses PMXT to match equivalent markets across Kalshi Polymarket, streams live order books, and shows the live YES prices side-by-side.
Screenshot: French Open markets with live cross-venue spreads.

Trump posted the USโIran ceasefire deal at 21:50 UTC on May 23.
Polymarket had been pricing it for 7 hours and 32 minutes.
By the time the post hit, 85% of the move was already done.

This data is free using the PMXT API. Crazy others are charging hundereds of dollars for this...
What the Polymarket book did around SpaceX Starship Flight 12 ignition.
In the hour before launch: 79ยข โ 88ยข as confidence built. The minute it lifted off: 88ยข โ 99ยข, ask side vanished, market resolved YES.

All archive data now live via API
Remember when we dropped the full Polymarket order book archive? 30M rows per hourly dump, raw parquet files, everyone loved it
The problem: you had to download 500MB-1GB parquet files, write your own parser, reconstruct the book yourself from tick deltas
That's over. You can now query historical order books directly from the API. 4 lines of Python. ๐งต

Kalshi has the best price 44% of the time. Polymarket has it 42%. It's a coin flip. $22B or $15B, neither platform consistently beats the other on price. And the gap depends entirely on what you trade.
The category matters more than the platform.

Kalshi just raised $1B at a $22B valuation. They claim 90% of U.S. prediction market activity. So they must have the best prices, right? We checked 1,812 liquid markets. Not even close.

This is why a cross-venue aggregator is so important!!!
"Prediction markets are efficient" is one of those things everyone says and nobody checks.
We checked.
Across 2,991 prediction markets, traders overpay ~50% of the time vs. the best available price.

@HyperliquidX's first BTC outcome market did 3x the volume of Polymarket and Kalshi combined.
@devpmxt now supports it.
9 prediction markets. One SDK. Trade and fetch data from all of them in one line.

Good work, @trylimitless!

A core idea of the rebrand video was to align it with our $2 billion volume milestone
By the time we posted it, we already hit $3 billion
$1 billion in <2 weeks
