To clarify, OP appears to be referring to the fact that more than 0.3% of all bitcoins are being held in P2TR addresses now.

23.2% of all UTXOs are P2TR outputs (see e.g. https://dune.com/murchandamus/bitcoins-utxo-set): https://i.stack.imgur.com/zvQIV.png

And about 38.5% of all transactions in the last week had at least one P2TR input (via https://transactionfee.info/charts/transactions-spending-taproot/): https://i.stack.imgur.com/XdZdC.png
