According to Cointelegraph, Bloomberg ETF analyst Eric Balchunas said that although he and ETF analyst James Seyffart still believe that there is a 90% chance that the Bitcoin spot ETF will be approved before January 10, they have not raised the probability beyond this number.
Although unlikely, if the spot Bitcoin ETF is rejected this month, it is likely that the SEC wants "more time" rather than an outright rejection. Because the time and effort invested by the SEC and Bitcoin ETF issuers means that Bitcoin ETFs are unlikely to be rejected outright at the last minute. If the SEC rejects it, the fund issuers may follow Grayscale's footsteps and file separate lawsuits against the regulator.
