Can someone explain what arbitrage (arb) means in the context of PI? Simply buying low and selling high before market conclusion I assume?

I bet on poll markets fairly regularly but it's always with the method Necc0 is describing (arbitrage/arbitration/whatever). The goal is to get negative risk. It really only works if you start buying NOs as soon as the weekly market opens. That way there's maximum time for crazy swings to buy lower NOs and sell your old higher NOs. If it's late in the week don't bother.

Here's an old screenshot:



if you look under the risk column you'll see that no matter what the average ended up being I would win AT LEAST $17.85. The gain is low because at the time I only had about $150 to invest.

And here is from the Texas primary, when I only had like $70 invested:



The best part about it is, if you manage to get negative risk, PI will add your winnings to your account even if the market hasn't closed yet!

You can make a pretty decent return on investment without obsessively watching the site. You just have to be willing to sit on the longer markets where you know what is going to happen but the pay off is a ways away. Or bet on shorter markets with the goal of picking the position to ride until the market closes instead of playing the swings. There's a lot less gain, but if you do it right there's not too much risk either.

It also has the advantage of keeping you from maxing out on a position only to see it evaporate in the time it took you to drive home.

This. If you think Hillary will be the next president, there are 7 contracts out there you can buy in at around ~70 cents each. Sure, you have to wait ~4 months to see if you're right, but its a ~30% ROI.

Just so you know, buying the shares at 70 means .30 in profit per share, which makes it more like a 45% ROI.

Who will win the White House?
Which Party will win the WH?
Will the next president be a WOMAN?
Will dems win landslide?
Will reps win landslide?

The last two are 370 EV or better, but if you think your guy will win you can bet "no" on the other's contract for more bucks.

There's also the state EV markets, where you can still get good buys on probable wins.

Directly Hillary wins markets:
Who will win the Election.
Which Party will win the Election.
Will a Woman Win the Election
Will the Republicans get at least 370 Electoral College votes. No on the contract.

Weaker Hillary wins markets:
Who will be the next Supreme Court Justice. Yes on Garland.
Will the Senate confirm any SCOTUS nominee before Obama leaves office. Yes on Garland.
Will the Senate vote on any SCOTUS nominee before Obama leaves office. Yes on Garland.

Even weaker Hillary wins markets:
Democrats get at least 370 Electoral College votes.
2016 voter turnout. No on B6, probably no on B5, pick your poison on the rest. 2012 had 129 million, 2008 had 131 million.

The various who will win X state markets also are tied to Hillary winning, but not all directly. Also there are states like New York, California, Texas, and Utah that probably don't matter unless either Trump or Hillary are crushing beyond all reason.

I included the 10% profit penalty, and the 5% withdrawal fee, assuming you put in fresh funds just for these markets and then immediately withdrew it all once you won


You can add "Will Republicans control the white house & congress after 2016" to this list

True, but now's a good time to start putting in some low rear end bids so you're first in line when Trump inevitably gets a convention bounce and everyone believes the sky is falling.

That's another part of the FTC no-action letter. As far as I know the RNOM markets are the only other ones to hit it. You have to wait for other traders to back out before you'll be allowed to place orders.

Didn’t PI formally request that the FTC lift this particular limit?

Was that shot down, or is it still working its way through the bureaucracy?

Do you mean arbitrage? That poo poo is hard for me to understand but I think it comes with practice. Some people must have their own self-built calcs.

Or do you mean simple yes/no markets?

I mean a tool where you can see how PredictIt would calculate your risk in a linked market. It would be a thing where you can set the number of markets in the linked contract, and then for each market you can set the prices for NO, and the number of shares you have. Then you could play around with the numbers to see how the risk changes.

I had an excel spreadsheet that would calculate this for me but it was from before linked markets when arbitrating was much more lucrative. I was occasionally pulling 8-12% ROI after all fees. It was mostly driven by the sheer number of somewhat valid Republican nominees and it being significantly cheaper to buy YES on a preferred candidate vs. NO on everyone else. That's not the case any longer.

so I know very little about brexit outside of reading a few articles weekly, but Gove just declared he wouldn't invoke article 50 until 2017 and I believe May has already said the same thing

I just bought some NOs here for 81c - market has barely moved in response: https://www.predictit.org/Contract/2982/Will-the-UK-trigger-Article-50-before-October-1#data

e: but I guess this Andrea Leadsom is the new Leave candidate? And she has 17% in the Who Will Be the Next PM market, so maybe this isn't as mispriced as it looks. That said, "Before Oct 1st" seems impossible right now, whether the winner is Leadsom or May

Yeah no one thought they'd ever be able to actually invoke article 50 until next year considering the UK won't have a new PM until September if they're lucky. That market isn't going to move much at all unless we get a real surprise on PM.

Lynch said that because she was getting questioned over hanging out with Bill the other day. I'm not sure if it's any different than Obama's "nobody is above the law" statements. I probably don't follow this story closely enough though, given my NO holdings :v:

There has not been a single bit of good news that has come out about this, other than apparently the passage of time. If you think that there's no way she'll get indicted, you probably should have already maxxed bet against it ("maxxed" being a relative term for the maximum you are comfortable with, it is relative). I seriously can't imagine anyone being like "Wow if anything I feel MORE confident about this not happening than I did for the previous six months of it being within ten percent of its current price."

What I'm struggling to understand is, in markets like these, there's little foreseeable reason to get out and sell your shares at .75. Yet we see hundreds of shares for sale at .75, .8. Why is that? Do people have open sell orders open for 'no'?

It could only be open sell orders for no or open buy orders for yes, right?
