Polymarket Trading Bots: Why Avoid Rotating Residential Proxies

Polymarket’s volume is exploding right now. The prediction market is a goldmine, and tons of developers spinning up bots to try and catch those split-second arbitrage opportunities.

Coding the strategy is one thing, but many people fail at step one: Infrastructure.

Specifically, if you are new to this, you are probably making the rookie mistake of treating this like a standard web scraping project and blindly using Rotating Residential Proxies.

Let’s skip the strategy logic for a second and talk about the two things that actually hurt your wallet: Bandwidth costs and Connection stability. If you choose the wrong proxy type, your bot might burn through your capital in proxy fees before it even makes its first trade.

The "Bandwidth Black Hole"

First, you need to understand how Polymarket data works.

If you are just scraping a webpage once an hour, it doesn't matter. But if you are doing high-frequency trading or real-time monitoring, you must use WebSockets. You need to listen to the Order Book stream in real-time, not sit there polling the API like a caveman.

This is where standard "Pay-As-You-Go" ($/GB) rotating residential proxies become a trap:

1. The Cost is Insane: WebSocket data flows 24/7. Especially during major events, the order book updates thousands of times per minute. You might think it’s just text data, but it adds up fast. Running a full monitor can burn through gigabytes daily. If you are paying per GB, you are going to cry when you see the monthly bill.
2. Disconnects are Fatal: The definition of a "Rotating" proxy is that it rotates. Usually, the IP changes every few minutes. The moment the IP changes, your WebSocket connection drops. By the time your bot reconnects, that arbitrage opportunity is gone.

The hard truth: Using pay-per-GB rotating proxies for WebSockets is basically burning money.

Why ISP Proxies (Static Residential) Are the Real Solution

At IPOasis, we support a lot of live crypto quant teams. The ones running stable, profitable bots? They are almost exclusively using ISP Proxies.

Here is why ISP Proxies are the industry standard for this:

1. Unlimited Bandwidth (Fixed Cost): ISP Proxies are usually priced per IP, not per GB. This means whether you process 10GB or 10TB of data, your cost is locked in.For a bot that needs to run 24/7, Fixed Costs are king. You don't need to stress about your data usage or limit the number of markets you monitor just to save a few bucks.
2. Stable Like a Server, Real Like a Home User: This is the "secret sauce" of ISP proxies.

• To Polymarket: Your IP looks like it belongs to Verizon, AT&T, or Comcast. It has a high Trust Score and looks like a real residential user (so Cloudflare won't block you).
• Under the hood: These IPs are hosted in data centers. They offer enterprise-grade latency and stability.

Simply put: You need a dedicated line that never disconnects and has unlimited data. That is an ISP Proxy.

Practical Advice: How to Configure Your IPOasis Proxy Pool

To save money while maximizing performance, I recommend a Hybrid Architecture. Don't put all your eggs in one basket:

Scenario A: Market Monitoring (WebSockets) -> Must Use ISP Proxies

This is your lifeline. Get a few high-quality Static ISP IPs from IPOasis.

• Setup: Route your WebSocket connections through these static IPs.
• Benefit: Zero disconnects, zero data anxiety. You can subscribe to hundreds of market tickers and receive millisecond-level updates without worrying about the meter running.

Scenario B: Scanning/Metadata (REST API) -> Can Use Rotating Residential

When you need to hit the /markets endpoint frequently to discover new events, you need to rotate IPs to avoid rate limits.

• Setup: Use IPOasis Rotating Residential Proxies here.
• Benefit: You get a fresh IP for every request, bypassing WAF limits. Since you are just pulling light JSON lists, the bandwidth usage is negligible, keeping costs low.

Final Thoughts

In quant trading, your strategy is the software, but your proxies are the hardware. If your hardware fails, your software is useless.

Don't lose money on slippage or missed trades just to save a few pennies on cheap, unstable proxies.

If you are serious about building a professional Polymarket bot, do it right from the start. IPOasis ISP Proxies are optimized for this exact scenario—low latency, unlimited bandwidth, and high purity.

Don't let a bad network connection be the reason you miss the next big trade.
