Shares of some of the top publicly traded Bitcoin mining companies have fallen amid a broader market decline, even after the U.S. Securities and Exchange Commission clarified on Thursday that mining operations “do not involve the offer and sale of securities.”
MARA (MARA), CleanSpark (CLSK), and Bitdeer (BTDR) are among the mining companies showing losses so far Friday, though they've all rebounded somewhat since earlier in the morning. Riot Platforms (RIOT), meanwhile, is relatively flat on the day after being down earlier Friday.
As of this writing, MARA and BTDR are both down about 1.5%, while CLSK has fallen by 4.5%. None of them showed a significant bounce after the Commission’s guidance circulated on Thursday afternoon, and they're currently underperforming relative to leading indices like the Nasdaq Composite and S&P 500, are down 0.03% and 0.4% respectively Friday as of this writing.

Bitcoin, Dogecoin in the Clear After SEC Says Crypto Mining Doesn't Violate Securities Law
The U.S. Securities and Exchange Commission said Thursday that proof-of-work mining—which underpins Bitcoin and some other blockchain networks—does not violate U.S. securities law. In its latest guidance to clarify rules for the fast-moving industry, the regulator said that mining operations do not need to register their actions as they "do not involve the offer and sale of securities." Securing crypto networks has been a controversial issue in the past, with the SEC under the previous administr...
Other major publicly traded crypto firms are also down on the day, with leading American crypto exchange Coinbase (COIN) dipping 1.4% and top Bitcoin treasury reserve firm Strategy (MSTR) down 1% so far Friday.
Consensus mechanisms like proof-of-stake (PoS) or proof-of-work (PoW)—the ways in which many major blockchains secure their networks and verify transactions—have drawn the ire of the SEC in the past. For example, in 2022, former SEC Chairman Gary Gensler indicated that proof-of-stake assets like Ethereum or Solana could be considered securities.
Thursday’s guidance, which makes specific mention of the proof-of-work consensus mechanism, didn’t do much for the price of the top mined assets like Bitcoin or Dogecoin either. The coins are down 0.1% and 1.1% in the last 24 hours, respectively.
The last day’s slide continues a poor trend for publicly traded Bitcoin miners, who recently reported a loss of more than $23 billion in collective market cap in a month’s span, according to a JP Morgan report.

Trump's SEC Is Ending Crypto Lawsuits and Investigations—These Are the Biggest
The momentum has shifted in the yearslong battle between top crypto companies and protocols and the U.S. Securities and Exchange Commission under the new Trump administration. The regulator, which now has a crypto task force led by longtime industry advocate Hester Peirce, is moving away from what Pierce and others have called “regulation by enforcement” to less hostile engagements with crypto. Thus far, those words have rung true with the SEC recently backing away from fights with multiple to...
The SEC’s latest mining guidance adds to a slew of crypto-positive headlines connected to the Commission, including a handful of dropped investigations and lawsuits, such as those focused on notable companies like Coinbase and Ripple.
