The statement is strongly supported by the evidence. Deribit's official X account (Sources 2 & 9) directly issued an 'Options Expiry Alert' for 'over $4.5B in crypto options'. A Yahoo Finance article (Source 6) explicitly confirms the date as 'Sept. 5' and attributes the data to Deribit. Another source (Source 1) provides a breakdown of Bitcoin and Ethereum options that corroborates the total amount, calculating to $4.56 billion.
