Currently, Gnosis Impact suggests that it would be highly advisable to not implement GIP1. This is because currently, one would be able to sell GNO for $154 under the condition that GIP is not implemented.
Why is no one doing this? Well - mainly since it is an arbitrage opportunity that is not extremely unlikely to occur. One could right now do the trades (and incur gas costs) and end up with a significant paper gain that however will only materialize if GIP1 is not implemented.
Given the current state of voting:
After 48 and ~40k GNO voted 99.9% voted for the proposal it seems highly unlikely that it will not be implemented.
So both assets DAI-no and GNO-no already right now have a value of close to 0 and for those assets the market will not be able to do price finding.
Long story short - market prices for DAI-no/GNO-no and DAI-yes/GNO-yes can only be found as long as it is still open which decision will be made and thus all of those 4 assets have value.
To not confuse voters I suggest changing the “Gnosis Impact” display to only show the prices if changes for the decision being made are between 15% and 85%.
