Early voting totals, polls and markets seem to indicate either GOP landslide—or an Election Day collapse (because so many voted early, some GOP voters stay home because of perceived lead, strong turn out from Dems, indpts and dual hate break for Harris).

Kalshi at $100M in volume negating “Americans can’t bet” argument. Robinhood launching trading will also add liquidity. Maybe some big trader will take EV+ Kamala 3x bet in size over the weekend.

The main thing I've learned from prediction markets (lifetime P&L roughly one used Mazda Miata, so don't take me too seriously) is that "buy an outcome based on available information and wait for it to happen" is pretty much always a bad trade. "Buy what is mispriced today" is much better. (not prediction advice)

Is there a way to arbitrage between various prediction markets markets?

Yes, there are many ways. An easy one is to buy contracts across multiple platforms. Since probabilities sum to 1 you can lock in a payout. For example, buy YES Harris for 35 cents on Polymarket and YES Trump at 55 cents on Kalshi. Congrats, you bought dollars for $0.90.
