They admit no returns.
But it does seem like a fun project and nowhere does it say anything about returns or profits so not scammy imo just funny meme backed code
The bot has zero risk management and I have a strong disclaimer on the github it is essentially a meme.
73% of all polymarkets do resolve to No though.
There's a good dataset on huggingface if you wanted to do some data science
I bet the average price for a no bet across these markets is 73 cents.
Edit: conversely, if the average no costs _more_ than 73 cents, but the 73% of all polymarkets resolve to No, that would imply that an everything-always-happens strategy is profitable (neglecting slippage)
The whole premise of gambling is that they don't
I wonder what it means exactly. Typical Polymarket looks like this:
X happens before May. [Yes][No]
X happens before June. [Yes][No]
X happens before July. [Yes][No]
...
So even if X ended up happens in December, it's still 12.5% Yes and 87.5% No?
Successful project imo.
I laughed. That's inspired. Quite the nerd-snipe as well, based on the rapidly accumulating threads on effectiveness, probabilities and markets.
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.
didn't look at the numbers, but this one sentence reminds me of selling options for 'passive income' (don't do that)
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.
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.
One of my go-tos on this is the Fukushima nuclear accident. IIUC there were plenty of folks in Japan who knew of the high risk. Perhaps many interested in nuclear energy outside of Japan, too.
But the average adult if asked about the prospect of a major nuclear incident occurring say, "tomorrow," would narrow their eyes in skepticism. There's almost an instinctual level seeding of doubt.
This can be a good thing. LK-99 was an excellent test of the dissonance from dramatic changes in reality and costs of inaccuracy.
The greatest VCs I have known are exceptional at suspending disbelief to test their ability to basically shape world building.
Consider this bot running on us military outcomes or something.
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.
It gives us normies a way to see what the powerful are thinking.
And, I'm not even contemplating gambling addiction. There's a huge market of people that just go to Vegas once or twice a year and come home thousands of dollars poorer. But they don't need it, they may not gamble outside of Vegas, or nothing that would signal an addiction.
If Polymarket were regulated like a casino, I’d actually have no problem with it.
You can make money off of all sorts of stuff. You can "sell" the bets, so there's lots of live pump and dump.
We've gone full circle. The bookie with no neck that smelled like onions was more honest than these platforms.
Like with this bot, I have no idea if that will still lead to actual positive returns. This might just be a remnant from a time when these betting lines were set less intelligently. But all things being equal, it seems logical that "boring" bets would have a better return in the long run than "exciting" bets as long as some betters are at least partially motivated by entertainment.
There's probably a lot of knowledge like this that sports betters have built up over decades that could apply to these new forms of non-sports gambling.
Here's how the mechanism works: I find that something is statistically worth $0.70 but I am able to buy it for $0.60 and statistically sell it for $0.70 (in the average). I make $0.10 each trade on average. Until you come along, copy my strategy and change $0.60 to $0.61 to frontrun my trades. Then someone else does it for $0.62. Until the market finally reprices to $0.70 where it should be. The guy who tries $0.71 loses money and stops, and then it goes back to $0.70. It's a stable feedback loop.
There are lots of positive EV strategies lying around in these inefficient markets that Citadel hasn't (yet) descended upon. The best advice I can give is if you find one, trade the hell out of it and don't open source it or tell anyone about it, because as soon as more people run it, it will cease to be positive EV and then after that it becomes an infrastructure game.
If it's popular on Github it probably doesn't work.
If you found something that works and is paying your rent, don't put it on Github. My 2 cents.
Yes, you can find positive EV trades on Wall Street as well. I've been diving into this a lot lately, all I can say is it's 10X harder to find strategies that work on Wall Street than prediction markets.
With one exception.
The one easy long-lasting anomaly to exploit on Wall Street which actually does NOT exist on prediction markets: "American stocks go up most of the time". This is actually a massively exploitable structural anomaly (you just buy and hold forever and effectively reap the rewards of a biased coin) and the source of the anomaly is mostly US monetary policy, US foreign policy, and US tech expertise put together. However, it still is an anomaly. The thesis that SPY will continue going up forever is also predicated on these things continuing to work the way they have in the past.
> yes this has to buy below 0.73 long term, the bot has a configurable ceiling set at 0.65 and checks for new markets buying closer to .5
What other question would you like to be backtested? This one is fairly easy
For example, for markets that are between 60 and 70, is it the case that around 65% of them resolve to yes?
I guess you want to take a certain time before out finishes, so focus on sports.
If you put all your money on no, you get 4% if you win, and if Jesus comes back and you lose, money won't matter.
This locks up your money in the meantime, right? If so, considering the fed funds rate is 3.64% (and you can probably get higher rates on stablecoins), a huge chunk of those "winnings" is going to be eaten up by the opportunity cost of the money.
Who does "you" refer to in this sentence? Polymarket itself?
I'm pretty sure if Polymarket itself decides it wants to screw you, you're gonna lose no natter what your strategy is.
(Manifold doesn't use real money, so there's more "free money" lying around waiting to be picked up than on most real-money markets)
