Not entirely true - since people had to enter a single point on their demand curve as a price and quantity of shares (instead of their entire demand curve) the market clearing price was artificially low. Hence the price pop on day one. To think about it more in depth - assume I enter a bid of 100 shares at $100. If the market clearing price is $50, I’ll be awarded 100 shares at $50. However, I was willing to buy far more than that at a higher price, so I’d go buy more shares on the open market, driving the price up.
