Show HN: Did prediction markets do any predicting this midterms?

I've heard so much about how prediction markets are the guiding light in this dark world. But when put head to head against polls or Nate Silver's FLIPR model, they are really a wash. Especially looking at flipped or close-by-polls races, there is no alpha compared to a traditional poll-based model. Was this obvious to everyone else too? Can we treat them like the entertainment they are and tax them for the terrible ads?

What’s with the mouse cursors? I can barely read this on mobile because it’s covered with “guest” pointers

I think it would be less distracting if they updated at a reasonable rate. If the pointer events were serialized using a small binary format, the update rate could be raised dramatically with minimal bandwidth increase over the current implementation.

Neat idea, thanks. Why show the cursors on here? I found them somewhat distracting and am not sure what purpose they're serving.

It's an interesting idea but I closed the page without reading it because it was so distracting.

I really think the main factor in determining if prediction markets are valuable is their predictions from outside election day. Once the “blue tsunami” was “expected” most of the markets shot overwhelmingly in one direction as the night wrapped up. You need to have a boundary for comparison that isn’t influenced by election night. Starting at 5AM is a decent cut point but I would argue the final poll date is the best comparison.

Love or hate PolyMarket, it should be on this list too.

Who are these people?

what are people suggesting is the "right" way for prediction markets to indicate that they are accurate? what should prediction market prices be if they are predicting accurately?

if you can predict accurately, you will win all your plays. If who you are predicting is the favorite, and the favorite wins, you will earn less money than if you can predict the upsets. That's what the markets do, you do the predicting, the market rewards you.

I'm actually not a fan of prediction markets for reasons.

But, them being "a wash" with fancy-pants models and expensive, not super-efficient polling processes is actually pretty remarkable.
