election

Here’s the Polymarket…market… for bets on the outcome of the US midterms in November over the last 7 days. You’ll notice a 7 percentage point (13% relative to a 54pp baseline) increase in the expected probability of the leading outcome. That’s a very big change, most of which happened over 3 days. In a $12.8 million market where the largest shareholder has $73k on the line, that is a very, very big move.

I don’t have any insight into what is happening here, I would simply note that there was to my knowledge no singular news item or event that appears to have sparked this. It’s just a great example of what makes betting markets so interesting. There is some tacit knowledge held by a relatively small number of inviduals, but within and through this market this information has now become at least partially observable in the form of a price. Now, to be extra, super, you just won’t believe how clear about this, I don’t have any insight to lay on top of this, no personal model to share, and I would strongly advise very nearly everyone against trying to participate in this market for personal profit. But, nonetheless, this is useful information. If you made me choose between a world with sports gambling or everything else gambling, I might very well choose “everything else.” At least the world captures some value from the revealed information that is, at least in part, subsidized by enabling a very real and serious addiction. I don’t know that we can say anything similarly positive about sports gambling.

Update: longer timeline as of 10am this morning (7/11 to 9/21)

Amendment 1: Partisan Election of Members of District School Boards

Currently, school district boards are locally elected and they do not have a party affiliation listed on the ballot. If passed, the amendment would permit party affiliation to be on the ballot. Partisan primaries would also be introduced, reducing the number of candidates in the general elections. The argument in favor is that party affiliation itself communicates information to voters. Removing that information forces voters to abstain, vote randomly, or to vote based on other information.

An argument against is that, in Florida, only registered party members may vote in primaries. If passed, parties will endorse particular candidates according to the primary results, winnowing the field. I happen to live in a county with an overwhelming republican majority, so the party-endorsed candidate will probably win. The outcome will be that the median republican primary-voter will choose the winning candidate in the primary rather than the median voter during the election. Voting “YES” aggregates information from a smaller set of voters.

I’ll vote NO.
