This is the third version of this headline I've published in this newsletter. And the answer may finally be yes: A spot bitcoin exchange-traded fund (ETF) may begin trading in the U.S. in the coming weeks.

Excitement over a spot bitcoin ETF – a regulated financial product that would give institutional and retail investors easier exposure to bitcoin's price without requiring them to invest directly in the asset – continues to grow.

The U.S. Securities and Exchange Commission (SEC) faces a Jan. 10 deadline for approving an application from Ark 21 Shares. It's widely seen as the final date by which the SEC may approve or reject the more than a dozen outstanding applications.

A number of signs point to an approval in the near future – like continued meetings between SEC staff, exchanges and would-be issuers, as well as a flurry of filings.

SEC staff met with representatives from the markets that want to list the products – the New York Stock Exchange, Nasdaq and Cboe Global Markets – on Wednesday afternoon, an individual told CoinDesk.

Fox Business first reported that the meetings were taking place, saying SEC attorneys from the Division of Trading and Markets met with representatives from the exchanges.

Over the past few weeks, SEC staff have also met with issuers to address various aspects of their S-1 filings, including having all issuers use a cash creation and redemption model instead of in-kind.

Cash creation means what it sounds like: Authorized participants will purchase shares of the ETFs from the issuers using cash, rather than directly acquiring the underlying asset.

Companies like BlackRock and Grayscale have argued before the SEC that the regulator should be comfortable with and allow in-kind creation. Georgetown University Associate Professor James Angel similarly argued in a letter to the regulator that only allowing cash creation would end up adding fees and other frictions to the various parties.

An individual familiar with an issuer's efforts told CoinDesk last month that issuers had been meeting with the SEC to pitch the regulator on allowing both cash and in-kind creations.

"If you offer cash and in-kind, you have more market participants, tighter spreads on the ETF, closer tracking to the underlying assets … and greater investor protections," the individual said.

However, the individual also noted that there may be a few reasons why the SEC may not want to allow in-kind creations at this moment simply due to how existing rules are structured.

The SEC may need to update its rules for how broker-dealers handle custody transactions before it can allow in-kind, the person suggested as one possible reason for the reticence.

"I think many of the issuers believe that they don't want the introduction of a bitcoin ETF to be the thing that forces the SEC to update the rules and regulations for how broker-dealers handle bitcoin," they said. This isn't an insurmountable problem – the SEC could allow other intermediary businesses handle trading for in-kind creations and redemptions, for example.

Also on Wednesday, Fidelity filed a form 8-A, which allows exchanges to list shares. While this form doesn't in and of itself mean the product has been approved, it is a procedural step that must be taken if approval does arrive. An individual at another would-be issuer said their company would also have to file a form 8-A.

James Seyffart, an analyst with Bloomberg Intelligence, said the filing is a registration that's needed for the shares to begin trading.

"What will actually dictate SEC approvals is 19b-4 and S-1 approvals," he said.

Bitwise previously filed a form 8-A, according to another SEC filing.

"There are two primary things that I'm watching and that others should be watching if they're interested," Seyffart said. "These ETFs need a 19b-4 approval order and they need a completed and effective prospectus, aka an S-1. Without both of those things, the ETFs cannot begin trading."

In the meantime, we have seen a number of amended filings addressing the cash creation model and naming authorized participants.

And seemingly riding on the wave of excitement, the T-REX Group (yes, really) filed for a number of inverse and long spot bitcoin ETFs, presumably in anticipation of a spot trust product approval. None of these actions are smoking guns, but they all hint at a likely approval.
