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.

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 as a small flat fraction of bankroll, scaled by per-archetype multipliers you control. Delfi backs the market favourite on every tradeable market that clears its archetype skip list and risk gates. The forecaster's job is to tune those gates over time, not to second-guess the crowd on individual trades.

03

Risk Manager

Before any trade executes, Delfi checks the portfolio: daily loss cap, weekly loss cap, drawdown halt, streak cooldown, dry-powder reserve. 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's estimates closely match real-world outcomes. That is the definition of calibration. The dashed line is perfect calibration; the teal line is Delfi.

Your funds. Your keys.
Your machine.

Delfi runs on your computer, not ours. Your Polymarket key never leaves your OS keychain. Delfi reads it only when it places a trade. Your wallet stays invisible to us by design.

  • ✓ We never see your wallet address.
  • ✓ We never custody your capital.
  • ✓ We never know which trades you make.
  • ✓ We could go offline tomorrow and your bot would keep running.

Try Delfi without risking a cent

  • Start in Simulation Mode.
    Every decision is what Delfi would make live. The only difference is that the capital is paper.
  • Watch Delfi prove itself.
    Let Delfi run for a day or a week. Read the reasoning, check the P&L, see how it handles volatile news. You decide when the track record is enough.
  • Switch to Live when the numbers convince you.
    Paste your Polymarket private key into Delfi and toggle to Live. Delfi keeps running at the same settings. Only the capital is real now.

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.

Common questions

Delfi is an autonomous Polymarket trader that runs entirely on your machine. It continuously scans every active prediction market, produces its own probability forecasts, and backs those forecasts with small, flat-sized stakes, all within the risk limits you set. You install it once like any other desktop app.
In an encrypted file on your machine, owned only by your user account. Delfi reads them only inside its own process; they never travel to any server we control. We can't see your wallet address even if we wanted to.
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 runs locally on your machine, never custodies your funds, sizes every trade by the same flat-fractional math regardless of how strong the signal looks, and shows you the full reasoning on every position.
You lose money on that trade. Delfi is probabilistic, not psychic. It aims to be right more often than wrong, not infallible. Over hundreds of trades, sizing discipline plus following the market favourite compounds into real returns. Daily and weekly loss caps you set during onboarding stop a bad streak from compounding.
$249 once. No subscription. All future updates included. Beyond that, you pay your model provider directly for forecasting API usage and Polymarket on-chain fees for trades.
Not to start. You can install Delfi and run it in Simulation mode forever, with synthetic capital and the same forecasts and risk math as live mode. When you want to switch to Live trading, you'll need a funded Polymarket account and its private key, both of which you already control.
Delfi never custodies your funds. Your capital stays in your own Polymarket wallet. Your private key lives in your OS keychain, not on Delfi servers. Delfi reads it only inside your process, only when signing a trade: never at rest, never in logs, never transmitted. We can't withdraw funds, transfer them, or see your wallet address. You can pause Delfi or delete the app at any time.
Yes. Delfi runs locally and does not phone home for trading decisions. Once installed, the app runs entirely on your computer.
Any time. The dashboard has an emergency stop button. Open positions stay open until they resolve. No new trades are placed until you turn it back on.
Polymarket and prediction markets are regulated differently in every jurisdiction. Some permit it, some restrict it, some prohibit it. Confirm legality in your own region before trading. If in doubt, consult a local advisor.
