what do you think about ARM and instacart ipo?

There are two very different companies but usually when it's so popular i think it will be well above ipo price on first day and then drop in a week? but ARM is suppose to be valued at above its previous market value. while instcart valuation has crashed so it is more of a value buy unless if you think it's valued less. $Arm Holdings (ARM.US)$ $Instacart(Maplebear) (CART.US)$
