When a player corporation gets to a certain size, that corporation can “go public” just like in the real world, they perform an IPO or an Initial Public Offering. The total assets the corporation has divided by a hundred thousand is that corporations starting volume. It’s volume or number of shares it has starts at $10 per share but doesn’t go over the corporations initial starting price. So this means that if corporation “XYZ Traders” were to go public with $10million credits (the minimum to go public with), their initial share count would be 100. If a corporation wants to create more shares, they can do so, but it will decrease the value per share. Example…

total assets / 100,000 = volume @ $10
volume = 100 @ $10

So if a corporation wants to immediately create 100 more shares…
100 shares = $10, 200 shares = $5, 1000 shares = $1

Stock prices can’t go below $1.
