You're not losing to the market.
You're losing to the machines.

Polymarket has become an algorithmic battleground. Machines read faster, trade faster, and never sleep. Every forecast you build has probably already been priced in by a bot ... before you finished reading the question.

The problem isn't what you know. It's how fast you can act on it.

An AI agent with four minds.

Everything a good trader does. Running for you 24/7.

Thinks

Reads the news. Checks historical base rates. Weighs structured data. Produces its own probability estimate for every market.

Calculates

Flat 1-3% position sizing, scaled by confidence in the call. Drawdown circuit breakers, daily loss caps, and event correlation guards. Never over-exposed. Never emotional.

Learns

Tracks its own accuracy by category and Brier score. Every 50 resolved trades it proposes calibrations for you to approve. Delfi gets sharper the longer it runs.

Explains

Every trade comes with its full reasoning: the probability estimate, the research sources, the gates it cleared, and the risk logic. You see what Delfi saw. You see why it traded.

Every trade passes through
three independent systems

01

Probability Engine

Delfi reads every active market and produces its own probability estimate, grounded in news, historical base rates, and structured data.

02

Position Sizer

Every trade is sized flat at 1-3% of bankroll, scaled by Delfi's confidence in the call. Two independent gates, direction agreement and minimum win probability, must clear before a dollar moves. Low-confidence calls get a smaller stake, not a skip.

03

Risk Manager

Before any trade executes, Delfi checks the portfolio: daily loss caps, drawdown circuit breakers, event correlation guards. If the book is already stressed, Delfi passes.

There are three kinds of Polymarket bots ... and then there's Delfi

Arbitrage bots compete on speed. Copy-trading tools compete on who to follow. Delfi competes on accuracy, discipline, and transparency, all at once.

Delfi is the only AI agent on Polymarket that combines deep reasoning with institutional-grade risk math. Everything else is a subset.

Delfi's estimates closely match real-world outcomes. That is the definition of calibration. The dashed line is perfect calibration; the teal line is Delfi.

New to Polymarket?

Polymarket is a marketplace for real-world questions. Each question trades between 0% and 100%, and the price is the crowd's probability. A question trading at 44% means the market thinks there's a 44% chance it resolves yes.

But the markets are often wrong. People bet on what they want to be true. They anchor on headlines and ignore base rates. A patient reader can forecast outcomes more accurately than the crowd. The hard part is doing it consistently, sizing each trade correctly, and walking away when the read isn't strong enough.

Delfi does all of that for you. It reads every tradeable market, builds its own forecast, sizes each trade to its confidence, and acts when the forecast clears every gate.

You don't need to be a prediction market expert. You just need an account with Delfi.

Before Delfi I was scrolling Polymarket at 2am like an idiot. Now I scroll it once a week and check P&L. Got higher returns and less anxiety.

Every Polymarket bot I looked at was a black box with marketing attached. No probability model, no sources, no sizing logic. Delfi shows all three on every trade. I can still disagree with a call, but I can't accuse the thing of being opaque. That's rare.

I'd never placed a Polymarket trade before. I connected a wallet with $400, picked the conservative risk profile, and let Delfi run. Three weeks in, I'm up roughly $150 and I check the Telegram summary over coffee. I still don't really understand prediction markets.

I tried three other Polymarket bots before Delfi. One was a copy-trading tool, one was an arbitrage scanner, one just didn't work. Delfi is the only one that actually thinks about each market.

Q&A before you sign up

Delfi is an autonomous AI agent that trades on Polymarket for you. It continuously scans every active prediction market, produces its own probability forecasts, and backs those forecasts with small, confidence-scaled stakes, all within the risk limits you set.
Most Polymarket bots are either arbitrage scanners (exploiting price inconsistencies at high speed), copy-trading tools (mirroring top traders), or basic momentum systems. Delfi is none of those. It's a reasoning-based AI agent that evaluates each market the way a sharp human trader would, with research, probability modeling, and calibrated risk sizing.
You lose money on that trade. Delfi is probabilistic, not psychic. It aims to be right more often than it is wrong, not infallible. Over hundreds of trades, calibrated forecasting compounds into real returns. On any single trade, anything can happen. All losses are capped by the daily and weekly risk limits you set during onboarding.
No. You can sign up for Delfi free today and explore the product without a Polymarket account. When you're ready to trade live, Delfi will guide you through connecting a wallet. If you're new to Polymarket entirely, Delfi is actually one of the easiest ways in. You get the benefits of active trading without having to become an active trader.
Delfi never custodies your funds. Your capital stays in your own Polymarket wallet. Delfi only has execution permission. It can place trades within the limits you set, but it cannot withdraw funds or transfer them anywhere. You can pause trading or revoke permissions at any time.
You can register for free and explore every feature: watch Delfi evaluate markets, read its reasoning, and review its live performance. When you're ready to trade live, subscriptions start at $69 per month, or $45 per month on the annual plan (a 35% saving).
In the United States, Polymarket is regulated under the CFTC following its QCX acquisition and amended order of designation. Delfi operates as an automated trading tool on top of a regulated exchange. In the United Kingdom, the European Union, Canada, Australia, and many other jurisdictions, prediction market rules vary widely. Some countries permit it, some restrict it, some prohibit it outright. Confirm legality in your own region before trading. If in doubt, consult a local regulator or legal advisor.
Yes, any time. Use the /stop command in Telegram or the emergency stop button in the dashboard. Open positions remain open until resolution. No new trades will be placed until you resume.

Stop reading. Start trading.

Sign up in three minutes. Delfi will take care of the rest.
