How likely is a Red Wave on Nov 8?

Ask the prediction market that President Biden is trying to shut down. [The CFTC withdrew its "no-action" letter to PredictIt in August.]  

The contract which pays $1 if Republicans win the Senate is trading at $0.64 (in RED), implying a 64% probability.  The market is also predicting an 89% chance of a Republican House.  

Note that these kinds of prediction markets are easy to set up and can help Firms make more accurate predictions about their industry, and about their own strategies.
