Nothing Ever Happens: Polymarket bot that always buys No on non-sports markets

My general observation is that people tend to underestimate the likelihood of black swan events (covid, financial crisis) even as it's pretty obvious they're happening. And then when they do accept it, they react too far the other way and assume it's never going to end.

I've had success playing the markets in these specific cases. I did fritter away a lot of my gains from the financial crisis thinking I was a genius market timer. But I learned my lesson and didn't waver once I jumped back in after covid.

In both cases I got out before a bulk of the crash and timed the bottom almost to the day. Lucky I know, but I had reasons for both. For the financial crisis it was when Bill Fleckenstein closed his bear fund and put it all in MSFT. For covid it was when it looked like the lockdown was working and NYC hospitals weren't going to completely fall over like Northern Italy or Wuhan.

For any non black-swan scenarios, I assume I'll never get one up on the masters of the universe and just leave everything in blended age-appropriate funds.

I'm very concerned about an AI crash and the future of white collar work in general. But it feels more like a slow death to me than a black swan. So I'm just hedging with bonds and cash and stocks that hopefully don't crash as hard in a recession.

This is what markets like Polymarket boil down to. Normies can't win. Some will, of course, but that's just chance and there's no way if ensuring it's you.

It's really no different than a casino: if you ever find yourself with more money than you walked in with, cash out and leave.

Best strategy for most people though is to simply not participate and you'll break even.

I've backtested this kind of strategy, and it had a good return (like 100% APR), but then I realized it was cheating by knowing when things are going to resolve. Often times it's not clear. Your return depends a lot on how quickly you can get your money out. I never got around to trying a strat that doesn't know the resolution time, which actually has to be manual cause it takes some judgement to pick things that you expect to resolve soon.

Also requires a lot of volume to be "predictable" obviously, since 1 loss sets you back 10-20 wins. It's surprisingly hard to find reasonable-liquidity markets after all your filtering. Many have huge spreads or thin books. Scare quotes around "predictable" because you never know if others will use this strat or a lot of unlikely events will happen due to insiders.

Another thing, just like the author, I was excluding sports in all the above. Yes Polymarket is famous for letting people bet on world events etc, but turns out it's still more about sports. Betting on the overdog in sports markets seems more appealing because there are plenty of those events with large volume, they're kinda homogenous, you know exactly when they resolve, and they're harder to rig. I simply never got around to putting real time or money into the overdog strat.

nice to see heroku still alive...

I drew the same analogy. You put up $0.95, a YES gambler only puts $0.05 (ignoring spread); you're providing "insurance" in case of a YES. In theory, even if the market prices reflected the true probability of the event happening, the more expensive side should be netting some "insurance premium" on average, right? Not sure, and idk how to observe if that's happening.

Polymarket is also holding onto the money in the meantime. Idk what they do with it, but it's not like some other platforms where they at least work with a bank to earn you some tiny interest on it.
