Hyperinflation usually occurs for one of two reasons:

1. Supply-side shocks such as disruptions in oil production, food production, etc. that cause shortages, leading to massive spikes in price. This happened in the 1970s during the oil crisis and led to stagflation. Zimbabwe had a crisis in food production, leading to hyperinflation.

2. Lots of foreign-denominated debt. Latin American countries experience hyperinflation because their debt is usually in USD rather than their domestic currency. Printing money to service foreign debt leads to hyperinflation. Weimar Germany had this problem when attempting to pay back the foreign-denominated debt reparations.

It's very rare to see demand-induced hyperinflation. That occurs when countries print way beyond the capacity of their economy to handle. If the US was at full capacity utilization and full employment, then an increase in the money supply beyond that would lead to inflation. But currently, the US is nowhere near full employment or full capacity utilization, so the threat of high inflation/hyperinflation is - to put it bluntly - nonsense.

You could make the argument that the stock market is overvalued because of current policy, but that is not hyperinflation.
