You could make one asic that supports all algorithms, and re-uses parts that overlap, or you could even create one asic per algorithm. This substantially increases the amount of design effort required, which puts it rather out of reach for smaller companies. But Bitmain could easily pull together a design effort of that scale, so they are even further advantaged there.
