The race for the United States’ first spot exchange-traded fund has officially begun after new 19b-4 filings by the Chicago Board Options Exchange (CBOE), which will “ultimately start the clock” for an SEC decision.

On Sept. 6, the CBOE filed two 19b-4 applications to the United States securities regulator, requesting for the ARK 21Shares Ethereum ETF and VanEck Ethereum ETF investment products to be listed on CBOE’s BZX Exchange.
