The terms of the bet are such:

I have staked 25k mana against David's (@dlin007) 90k mana.

David wins the bet if Trump outperforms his final (morning of election day) RCP polling averages (Trump vote share, not margin) in all three of MI, WI, and PA, and does so by an average of at least 2.5%. I win otherwise.

TLDR: therefore, what you're betting on in this market is the outcome of this bet; resolves YES if I win (Trump doesn't significantly outperform) and NO if David wins (Trump significantly outperforms).

@Joshua @SemioticRivalry and @shankypanky are arbitrating and provided escrow.

I MAY bet in this market. If the resolution is at all controversial, then the team of 3 mods listed above will determine the resolution! If they decide to resolve the bet to some PROB or cancel it, then this market will resolve accordingly (although I really don't see why or how that would happen). I would ask those 3 mods to therefore not bet in this market to avoid the appearance of impropriety!

I've set the close date well after the election in case it comes down to a recount or something stupid, but hopefully this should resolve shortly after the election (as soon as the bet resolves itself).

lol RCP, ben you get a free win

Ben indeed got a free 0.4 percentage point boost though it did not matter a single bit.

@benshindel Can this resolve now? I see David already conceded.

@TimothyJohnson5c16 ya I haven’t been paid out yet, but I’m assuming the arbiters are just taking their time, I’ll ping them

bought Ṁ3,000 YES

It does look increasingly likely that I will end up surviving and winning this bet (although we will wait for vote counts to be finalized, etc). I thank @dlin007 for being a great counter-party! It was a pretty close one, and looks like the polling error from the RCP vote share will end up being about 1.8%.

I'll note that as the results stand now, it looks like this bet would have resolved the same way if we'd bet based on margin of victory (1.6%) instead of vote share, and also if we'd used Silver Bulletin or 538 instead of RCP (with either vote share or margin, all about 2.1-2.3%) though it would've been a bit closer! There's surprisingly only about a 0.7% difference between the most and least favorable (to me) of these selections.

@benshindel yeah, it was looking like I was going to win on election night, but the later counts have doomed me. You can resolve in your favor. I was directionally right, but got undone by hubris, so I can still claim a moral victory

Not looking good, friends... but at least I hedged on this market!

@benshindel I hate this market. The vote share thing is such a trap. I also overlooked the undecided/third party number in polls vs results

@PlainBG ya, I’m sorry, but the resolution criteria for this market had to match the exact terms of the bet, and those were the terms

@benshindel Not your fault and I'm not asking you to the change the terms

Forgot to check this morning, but I don’t think they’ve changed since then

@benshindel

RCP forecasts Trump vote share at 47.8 in MI, 48.2 in WI, and 48.5 in PA.

He needs to outperform all 3 and by an average of 2.5 points to win!

bought Ṁ173 YES

It looks pretty good for you now!

Current count:
PA - 50.5%
WI - 49.7%
MI - 49.7%

sold Ṁ185 NO

@TimothyJohnson5c16 Yes indeed! (I've been selling my hedged shares for the last 20 hours or so)

lol RCP, ben you get a free win

@nikki it’s like within 0.5 points of Silver Bulletin I’m p sure

@nikki I mean currently there's a 0.2% difference between RCP and Silver Bulletin in PA, 0.6 in WI, and 0.5 in MI, and I'd expect those to narrow as we get closer to election because RCP is pure polling and Silver Bulletin is modeling predicted final vote share

@benshindel RCP is a hack poll aggregator, not "pure polling"

They make stupid assumptions like polling error being correlated across years

@nikki I’m not trying to defend them tbh, but I do think they’re quite in line with other polling aggregators this cycle

@nikki lol indeed!

@dlin007 @benshindel I was competely vindicated. They were the most R biased polling average this year.

Also I can't read. These numbers are from Nate's polling averages, not his model.
