The Securities and Exchange Commission won’t appeal a court’s scathing reversal of its decision not to let Grayscale convert its bitcoin trust into a more investor-friendly exchange-traded fund, Reuters reported Friday, possibly clearing the way for the first bitcoin ETF in the U.S.

The markets regulator had until midnight Friday to decide on challenging the court’s decision. The Reuters report suggests the SEC will let that deadline come and go without appealing.

In August, the D.C. Circuit Court of Appeals ruled that the SEC’s denial of Grayscale Investment’s application to convert the Grayscale Bitcoin Trust (GBTC) into an ETF was invalid and must be reviewed, calling it an “arbitrary and capricious” rejection. The court said that federal agencies are required to “treat like cases alike.”

“The Securities and Exchange Commission recently approved the trading of two bitcoin futures funds on national exchanges but denied approval of Grayscale’s bitcoin fund,” Circuit Judge Neomi Rao said in August.

SEC spokespeople didn’t immediately respond to a request to confirm the agency’s decision.

It’s unclear how the SEC will proceed in its next round with Grayscale’s application. The agency still has the authority to deny it for other reasons besides the ones courts shot down, though Grayscle could challenge those again in court.

Grayscale first applied to convert its closed-end fund into an ETF in October 2021. GBTC is the largest cryptocurrency fund in the world and has been trading at a discount to its bitcoin holdings since February 2021. That discount reached almost 50% at one point but has since retreated to levels around 17%.

Grayscale has long advocated that the conversion of GBTC to an ETF would eliminate the discount as it would close the gap between the price and the underlying bitcoin. The structure of ETFs allow for a creation-redemption model which means new ETF shares can be created to meet demand or redeemed to reduce supply.

Grayscale – a unit of Digital Currency Group, which is also the parent of CoinDesk – is among a number of other entities that have filed for bitcoin spot ETFs. BlackRock and Fidelity are among those also awaiting approval from the SEC.
