According to CoinMeta, as reported by Glassnode, BTC's treasury company is currently in a profitable state, but has hardly made any purchases. The cost basis of BTC they hold is approximately $80,000, and since September 18th, the price has been above that level. In a profitable situation, purchasing behavior can be self-reinforcing: purchases drive up prices, higher prices boost their stock value, which in turn provides funds for more purchases.
