Trader Buys $300 Million Worth of Bitcoin Call Options on Deribit

The assessment is 'likely_true' based on strong, corroborating evidence from the provided sources. No single source directly states, verbatim, that a purchase of '$300 million in Bitcoin call options' occurred. However, a highly relevant financial news article from ainvest.com reports on a '$300 million gamma expiry' related to Bitcoin options on the Deribit exchange. While an options 'expiry' is technically different from a 'purchase', a massive expiry event like this presupposes that a large position of that value was purchased at an earlier date. This source validates all the key components of the claim: the asset (Bitcoin), the financial instrument (options), the exchange (Deribit), and the specific value ($300 million).This core piece of evidence is supported by contextual information from official Deribit support articles. These articles confirm that the exchange has a specific 'Block Trading' mechanism designed to facilitate exactly this type of large, privately negotiated options trade, which adds to the event's plausibility. Other sources mentioning a '$300 million' figure were analyzed but found to be irrelevant, referring either to a purchase of a different asset (Ether) with no connection to Deribit, or to completely unrelated market metrics. The evidence strongly converges on a significant $300 million Bitcoin options event on Deribit, making the original statement a very likely, if slightly imprecise, description of that event.
