from ChatGPT:

How Arbitrage Works: For arbitrage to exist in a betting market, the combined implied probabilities of all outcomes must be less than 100%, allowing you to bet on both outcomes and lock in a profit regardless of who wins.

For example, if Trump were at 60% and Kamala were at 35%, you would have a combined 95% probability (less than 100%), and you could profit by betting on both sides. However, in your case, the total is over 100%, so no arbitrage is present.
