Arbitrage the future.

Neural Bet is an autonomous arbitrage engine. It finds price gaps between Polymarket and Kalshi and takes the same position on both sides in 108 ms. It never predicts an outcome: it locks the gap.

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.

Idea 1 of 3

A market is a question.

"Fed cuts rates in June?"
YESNO
$0$0.50$1
$0.42=42%chance it happens

A YES share pays $1 if it happens, $0 if not. Its price is the probability the crowd gives it.

Idea 2 of 3

Two venues, two prices.

"Fed cuts rates in June?"
Polymarket$0.42
Kalshi$0.45
$0$0.50$1$0.00
3¢ gap

Polymarket and Kalshi price the same question separately. For a few minutes, they disagree.

Idea 3 of 3

Buy both sides for less than $1.

YES $0.42NO $0.55always pays $1.00
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.

See it for yourself

Choose the price gap between the two platforms and an amount. Whatever the market decides, the result is the same.

Same result either way. That is what "delta-neutral" means: the engine earns the gap, not a guess.

02How it works

Four steps. Under one second.

Delta-neutral by construction: the engine wins whichever side resolves. Follow one opportunity from the order book to the locked profit.

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.

Canonical id mkt_a9f2 · PM + KAL
03 · Price

Compute the true edge after frictions.

Fees, slippage, settlement risk, USDC/USD conversion: everything is priced in. If the net gap clears the threshold, the engine fires.

Gross 4.12% → net 2.81%
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.

Under the hood
Non-custodial

Your funds stay yours.

Same model as Morpho vaults: deposits go into a non-custodial vault. The engine can allocate them to its strategies, never withdraw them. You follow your position in real time and withdraw whenever you want.

Capacity

Up to $5M, same engine.

Position sizing adapts to book depth. We never push through the book, and never ask you to.

Transparency

Every day, published.

Your capital is tracked in real time in your client space, and the track record is updated every day, negative days included. Nothing is smoothed, nothing is hidden.

04FAQ

The questions people ask before they write to us.

Straight answers. If yours is missing, just ask.

Write to us
Do you hold my funds?
No. Neural Bet works like a Morpho vault: your deposit goes into a non-custodial vault, not into a Neural Bet account. The engine is only allowed to allocate the funds to its arbitrage strategies, never to withdraw them. You stay the owner of your position, follow it in real time and can withdraw whenever you want.
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.

Performance disclosure

Every figure on this site comes from the engine's daily results, as recorded on the Neural Bet owner dashboard. One result per day since March 11, 2026, published as is, negative days included.

  • Net of fees. Figures are shown after Neural Bet's share (50% of profits). They are what clients are credited.
  • Not compounded. Profits are credited daily and not reinvested: the cumulative return is the sum of the daily returns. The growth chart of $10,000 follows the same method.
  • Daily close. Each day closes at 2:00 am, Paris time. The day in progress is only added once it has closed.
  • Examples. The animation at the top of the page and the simulator use example prices to explain the mechanism. They are not live results.

Risks. Arbitrage reduces market risk but does not remove every risk: a venue can fail or suspend a market, two venues can settle the same question differently, an order can be only partly filled, and stablecoins and regulations can change. Past performance is not indicative of future results. Capital is at risk.
