well, the polls feed into polymarket predictions

yeah but their role will be much smaller. it's like asking people which burger they want to buy - Big Mac or Whooper. nice data point but def not enough to determine who will sell more burgers in Q4. that's why hedge funds use more complex prediction models.

If there aren't polls, how does the prediction market know how to price?

yeah, I don't think polling is going away. If anything, the polls were mostly correct and it was the media interpreters / modelers that made them less accurate.

If there is no market research on burgers, how does the hedge fund know how to prize McDonald's and Burger King? 

They analyze many things - social media sentiment, how many trucks leave their warehouses, how efficient they're at operations and so on.

Ofc with stocks it's easier because a lot of data is public, but I'm pretty sure you can gather a lot of data from politics, too. I'd be surprised if bigger hedge funds haven't been doing it for some time given how much impact these results have on stock prices.
