The next president of Argentina will be Javier Milei after his opponent Sergio Massa conceded on Sunday evening, saying "Argentines chose another path." With roughly 87% of the votes counted, Milei had 56% of the tally versus Massa's 44%, according to Bloomberg. Trading quietly through most of the weekend, bitcoin began rising late Sunday afternoon on chatter about a strong showing for Milei. Following Massa's concession, the crypto is higher by around 2% over 24 hours at $37,150. "We have to understand that the central bank is a scam," Milei said earlier this year when asked about bitcoin. "What bitcoin is representing," he continued, "is the return of money to its original creator, the private sector."

On Friday, the notional bitcoin (BTC) open interest, or the U.S. dollar value locked in active bitcoin options contracts, rose to a record high $15 billion. The figure has more than doubled since late September, topping the $14.36 billion peak registered during the bull-market days of October 2021. Back then, BTC traded above $60,000; today it's about $37,200.

At press time, notional options open interest had dropped back to $13.8 billion. In contract terms, open interest stood at over 376,000 BTC, nearly double the October 2021 tally, but well short of the record 433,540 BTC of March this year. On Deribit, one options contract represents one bitcoin.
