The United States Securities and Exchange (SEC) has begun accepting filings by exchanges in a sign toward approval of listing a spot Bitcoin ( BTC ) exchange-traded fund.

On Jan. 5, the Nasdaq Stock Market filed 19b-4 amendments for spot BTC ETF applications from asset managers BlackRock and Valkyrie, with others expected. The filings are one of the last stages in the SEC approval process, but S-1 documents must be completed in order for U.S. exchanges to begin listing shares of investment securities with direct exposure to crypto.

Some experts have speculated that final approval for the spot Bitcoin ETFs will drop before Jan. 10 — the deadline for an offering from ARK Invest and 21Shares. A potential approval could mean greater adoption of crypto in the U.S. and worldwide.
