Yeah, if you think she's gonna win and feel comfortable betting money on it, then go for it.

However, sometimes you can familiarize yourself with the rules of a contract and try to maximize chances of winning that way. For example, if candidates X and Y are both running for Senate, and you feel confident that candidate X will win, all things being equal, I would recommend buying some [Candidate Y No] shares. If X wins, you win. If Y wins, you lose. But if Y wins but then gets hit and killed by a bus the next day, you'll still win, as Y will never be sworn into office. I've never had anything like that happen in any of the markets I've bet on, but it doesn theoretically give you an edge. That being said, if [Candidate X Yes] shares are cheaper than [Candidate Y No] shares, then you need to weigh the possibility of increased returns versus a slightly increased chance of winning. Really, that's a personal calculation that you need to make on a case-by-case basis.

So I read thru this multiple times, and all I can say is: wut. :psyduck:

Click on the link that says: Your Risk in this Market Is: $X.XX

It will give you the breakdown of your payouts for each contract, and your total risk for the market. In this case, you probably had another contract in that market and so your overall risk increased. As has been said, it can be unintuitive. But it can also be profitable: if every YES contract in the market adds up to 110c or more, you can guarantee a profit by shorting every contract because your overall risk will go negative. In that case, PI just credits you the negative risk. So for that market I had negative risk of $35 (PI gave me back $35), plus I'd win $30 more if 217- hit.

Here's another example:
I have the full $850 invested in four different contracts. But because they act as a hedge against one another (I can only lose one), this combination of bets only "costs" me $614. So my payout if none of the above hits will be my maximum risk ($614) plus the payout for that scenario $473. If I sold one of the contracts at 99c I would take the profit, but at the same time as PI credits me the profit it would subtract from my account the additional risk I'm exposed to.

Really, that's a personal calculation that you need to make on a case-by-case basis.

Also this is, all things considered, correct. NO covers you for significantly more outcomes than YES - including the hit by a bus thing. Also, NO shares are often cheaper than the YES shares for the same outcome.

On the Pelosi thing, one of the scenarios being discussed is that Republicans could vote for her. In that scenario, a higher number of Democrats could vote no and she could be speaker. So it's not precisely the case that they represent the same thing. Figuring out what scenarios could happen that would gently caress you over is part of the game.

Also this thread is making me realize how inured I've become to betting larger amounts.

best way to understand negative risk is a thought experiment.

say you have a market with two contracts. one contract will resolve yes, the other no. you can buy yes or no in each contract. somehow you are able to buy a share of no at 1c in each contract. so the contract that resolves yes loses you a cent in that contract, but you gain 99c in the other. you are guaranteed a profit of 98c in this market no matter what. now note the yes shares at the time you bought each cost 99c, so they add up to 198c.

now do this for the same setup, but you bought no shares at 2c. leads to a guaranteed 96c profit. and note the yes prices add up to 196c.

now keep doing this increasing the prices you bought no at. you’ll eventually see buying no at 49c in one contract and 50c in the other is the least, though guaranteed, profitable negative risk arrangement. and those yes shares would add up to 101c

BUT WAIT! there is one element we forgot for the sake of making that explanation as clear as possible—fees!

basically, after including fees, the least, though guaranteed, profitable negative risk arrangement is when the yes side of your no shares add up to 109c.

The rules include written answers, though I am still new at this and have yet to be totally burned by a predictit ruling.

quote:

On or before December 31, 2018, Donald Trump, while serving as president, shall provide sworn testimony, whether written or oral, to Robert Mueller or one or more other members of the Special Counsel for the United States Department of Justice team, in the course of their investigation of Russian interference with the 2016 presidential election or related matters. Disclosure by the White House, the Special Counsel team, and/or an authorized representative of the Department of Justice that such testimony occurred must take place on or before that date.

PredictIt’s decisions and determinations under this rule shall be at PredictIt’s sole discretion and shall be final.

There could also be some question about what constitutes a disclosure that such testimony took place, but with Giuliani going on record that seems unlikely as well.

I think really this market is an opportunity to make money on the difference between the title and the rules- the title sounds like a face to face interview while the rules are pretty broad.

The comments are typically 60% hapless chuds raging out, 30% pure trolling/bait, and 10% whales styling on the chuds/idiots/trolls and bragging about winning.

Oftentimes you can tell when a market is ripe by the sheer volume of chudspam. They almost universally just pick the Republican to win/outperform regardless of anything else

Abel basically covered this, but if you see a market where the "Sell Yes" prices add up to 110+, it's pretty much guaranteed negative risk if you short every contract. You can test this by buying one share of each contract.

The most profitable "best" way to do this is to try to short at even higher than the "sell yes" price, but this means you are hoping that your orders will fill before the price moves. "Sell Yes" is the price at which you can short right away.

How's that going so far? I got into a negative risk position by shorting everyone hoping it would be not any of them, but then changed my mind and sold everything for +$3. Hooray.

Just now starting to draw out some of my winnings for the year that I can't find dumb markets to stash them into. Already have maxes in shorting all of Comey, Ohr, Abedin, Clinton, and Comey charges.
