Prediction markets, explained in 90 seconds.
No finance background needed. Three ideas are enough to understand exactly what the engine does, and why it never needs to predict anything.
Two venues, two prices.

Kalshi$0.45
$0$0.50$1$0.00
3¢ gap

cost $0.97
+$0.03 locked, YES or NO
YES on one venue, NO on the other: one of them always pays $1. Pay less than $1 in total, and the difference is yours.

02How it works
Four steps. Under one second.
The engine accounts for both possible outcomes. Follow an operation from the price difference identified to the result obtained.
108 msExecution window
01 · Ingest
Read every order book, 40 times a second.
A persistent, low-latency mirror of every active market on Polymarket and Kalshi. Full depth, no polling: the engine listens to the venues' live streams.
Round-trip 24 ms · 31 ms · 1 204 markets tracked
02 · Match
Recognise identical markets.
A language-model pipeline maps both venues to canonical contracts, so "Trump wins 2028" on Polymarket and its Kalshi twin are treated as the same question, priced differently.

03 · Price
Calculate the gain after costs.
Fees, price changes during execution, settlement risk and USDC/USD conversion are all included. The engine starts the operation if the remaining difference exceeds the required threshold.

04 · Execute
Take both sides. Atomically.
Buy YES on the cheaper venue and NO on the other, simultaneously, within a single 108 ms window. If one leg fails, the other is unwound instantly.

04FAQ
The questions people ask before they write to us.
Straight answers. If yours is missing, just ask.
Your question is not here? Write to us: a human replies in under 20 minutes.
Write to usWhere do my funds go?
Your funds are transferred to NeuralBet and placed in a Morpho-type vault. They are used for arbitrage operations. You can follow every transaction in the mini app.
What happens when there is no arbitrage opportunity?
The engine sits flat. We would rather earn zero than force a bad execution. On a calm day, it completes fewer than 100 arbitrages; on a volatile day, more than 200.
How do you charge?
Only on profits. Neural Bet keeps 50% of the profits generated, and nothing else: no subscription, no management fee, no hidden cost. If the engine makes no profit, you pay nothing. Every figure on this site is already net of this share.
Is this legal where I live?
Yes. Neural Bet operates within a fully legal framework. We do not accept US clients (citizens or residents of the United States), nor persons subject to US sanctions. Rules vary from one country to another: write to us and we will review your jurisdiction with you.
