Automated arbitrage across prediction markets. BTC Up/Down module on @Solana. 90ms execution. Powered by @jup_predict. Runs 24/7.

[PolyArbiter @PolyArbiter]

We built the cleanest BTC Up/Down bot on Polymarket.
⁠
We engineered the entire stack from scratch around one principle: never bet on outcomes, only capture mispricings.
⁠
How it works:

When YES + NO sums to less than $1.00 on Polymarket’s 15-min BTC market, the engine fires both sides atomically via Jito bundles. Total cost: $0.97. At resolution, one side always pays $1.00. Locked profit: 3 cents per dollar deployed.
⁠
BTC’s direction is irrelevant. The math already paid.
⁠
We don’t predict. We capture.
⁠
Architecture:
- Yellowstone gRPC at 1-5ms orderbook latency
- Jito atomic bundles, both legs fill or neither does
- 91ms median detection-to-fill
97.8% fill rate over 30 days
- Auto-hedge engine for partial fills in 4.2s

How to plug in:
1.Sign up at PolyArb (link in bio)
2.Copy PolyArb dedicated RPC URL from the dashboard
3. Open @jup_predict on Solana
4.Paste the RPC into Settings → Custom RPC
5.Activate the BTC Up/Down module

Free to use. Profit-share only. No subscription. No upfront cost.

This is the week the BTC Up/Down module was built for.

BTC -10%. $1.5B liquidated. Polymarket’s 15-min market repricing every few seconds. The engine just recorded +94% capture volume vs last week.

While leveraged traders got wiped, our users are still green.

How to use the engine:

1.Sign up at PolyArb
2.Copy your dedicated RPC URL
3.Paste into Jupiter Predict on Solana
4.Activate the BTC Up/Down module

Free to use. Profit-share only.

Throttles. The engine sizes to available depth, not to a fixed target so during the cascade it took smaller positions rather than eating slippage.

The trade-off is real: we left some spread on the table on the deepest mispricings because the book couldn’t support full size. But zero failed legs and sub-1% drawdown across the week was the priority. Glad it held up on your end 🙏🏼

[PolyArbiter @PolyArbiter]

@sh1bvm1 The +18% median is across 740 wallets, not our personal P&L. Profit-share exists so we only get paid when users make money. Different model from subscriptions for a reason.

[PolyArbiter @PolyArbiter]

One month ago we shipped the most powerful BTC Up/Down bot in the market. Free to use, profit-share only.

It’s been printing ever since.

The mechanic: when YES + NO sums below $1.00 on Polymarket’s 15-min BTC market, the engine fires both legs atomically. Both land in the same Solana block or neither does. One side always settles at $1.00. Profit is locked the instant the legs fill before the market even moves.

You plug in once. The engine does the rest.

5.Activate the BTC Up/Down module

5 minutes. That’s the whole setup.

Nothing else executes BTC Up/Down like this.

@cryptobullying 😂

[PolyArbiter @PolyArbiter]

@0xCristal Best stack in crypto right now. Boring on purpose 🥱🤝

[PolyArbiter @PolyArbiter]

@kaivornxbt That’s the entire thesis. Prediction is variance. Capture is math. Glad you’re on the right side of it 🤝

[PolyArbiter @PolyArbiter]

@slash1sol That’s not adjustment to luck. That’s adjustment to math working 🪄

[Polymarket Developers @PolymarketDevs]

Scheduled CLOB maintenace tomorrow, May 27 at 12:10 UTC.
- Intermittent trading for ~5-10 min during the window.
- Brief post-only mode after restart (~2 min) before normal matching resumes.

@parlettodotbet @jup_predict When profit locks at fill, outcomes cluster around the median instead of fanning out more wallets doesn’t widen the distribution, it just confirms it 👌🏻

[PolyArbiter @PolyArbiter]

@3jack23 @jup_predict 97.6% fill on $40K size is solid depth-aware slicing holds up well at that capital. Glad the numbers line up on your end 🙏🏻

[PolyArbiter @PolyArbiter]

@polybacktest @jup_predict 👀

[PolyArbiter @PolyArbiter]

@5aigdo @jup_predict Usually one mispricing sliced into multiple fills (depth limits prevent firing the full size at once). Sometimes it’s distinct events back-to-back windows opening with their own mispricings. Check the market IDs in your fill history to tell them apart

[PolyArbiter @PolyArbiter]

@connorcrd @jup_predict Agreed it’s the stat that actually matters. Returns get the attention, but drawdown tells you whether the execution holds. 1.3% over 30 days means the atomic legs are landing clean

[PolyArbiter @PolyArbiter]

@RetroChainer @jup_predict That’s what removing the prediction looks like 😉

[PolyArbiter @PolyArbiter]

@0xCristal @0xwhrrari @jup_predict Locked at fill. Settlement just delivers what’s already yours 🤝

[PolyArbiter @PolyArbiter]

@kaivornxbt @jup_predict 🤝

[PolyArbiter @PolyArbiter]

@recogard @jup_predict That’s the design. Median is median because most wallets cluster tight around it atomic execution keeps variance low across the board 🤝
