SEC freezes Nasdaq’s Bitcoin options approval as CME wages jurisdictional turf war
The SEC granted Nasdaq conditional approval for QBTC Bitcoin options in May 2026 on an expedited basis, initiating the regulatory process for the product. Nasdaq designed QBTC options to track the Nasdaq Bitcoin Index, which divides the CME CF Bitcoin Real Time Index by 100. CME's Bitcoin futures and options use the same underlying CME CF Bitcoin Real Time Index benchmark as Nasdaq's QBTC options. CME Group filed a jurisdictional challenge around June 11, arguing Bitcoin is a commodity and Nasdaq's options should fall under CFTC oversight. The SEC's conditional approval required CFTC exemptions before Nasdaq's Bitcoin options product could officially launch. The full SEC commission froze Nasdaq's QBTC options approval around July 31 following CME's jurisdictional challenge, opening a public comment period through August 24. CME operates regulated Bitcoin futures and options under the CFTC framework and views Nasdaq's product as competing through the wrong regulatory channel. Nasdaq structured QBTC to fit securities regulations, aiming to leverage its existing infrastructure and customer base on Nasdaq PHLX. The SEC's review has delayed the product launch, with no guarantee the original approval will be reinstated after the comment period ends. Two possible outcomes include Nasdaq registering QBTC with the CFTC or restructuring the product to fit SEC jurisdiction, though the latter is unclear. CME argues that exemptions cannot simply transfer regulatory authority from the CFTC to the SEC, prompting the SEC to review jurisdiction carefully.
SEC to review Nasdaq bitcoin options approval after CME challenge
In May, the SEC granted Nasdaq PHLX conditional approval to list cash-settled bitcoin index options under the ticker QBTC, pending CFTC exemptions. The CME Group challenged this approval in June, arguing that bitcoin is a commodity and options tied to it fall under CFTC jurisdiction, not the SEC's. The SEC's May approval assumed the CFTC would grant exemptions allowing Nasdaq and the Options Clearing Corporation to offer the product through the securities market. However, the CME argued that agencies cannot use exemptions to transfer regulatory authority from one agency to another, contesting the approval's basis. Nasdaq's proposed contracts would use CME CF benchmarks for both their underlying index and final settlement price, linking them closely to CME's data. The approval remains suspended while the full SEC commission reviews the earlier decision, with QBTC trading halted during this period. Interested parties have been invited to submit comments supporting or opposing the approval by August 24, as the stay has been in place since June 11. If the CME's position is upheld, the SEC would lack authority to approve QBTC, requiring Nasdaq to register under CFTC regulations or redesign the contracts. The CME already operates regulated bitcoin futures and options markets, while Nasdaq's QBTC would compete without registering under the CFTC framework. The CME's petition warned that approving QBTC could set a precedent allowing securities exchanges to list derivatives on other commodities, expanding regulatory ambiguity.
Bitcoin mining capitulation: difficulty falls 19.9% as miners pivot to AI
Bitcoin mining difficulty has dropped 19.9% from its all-time peak, marking the third deepest decline since ASIC hardware became standard. This decline is notable for both its depth and duration, extending approximately 287 days, one of the longest sustained contractions in Bitcoin history. The July 25, 2026 adjustment showed a negative 0.74% change, the ninth downward adjustment of that year. A previous major drop in June 2026 was 10.09%, ranking as Bitcoin's 11th largest single downward difficulty adjustment ever. Bitcoin's difficulty adjustment occurs every 2,016 blocks, roughly every two weeks, recalculating mining difficulty based on block arrival times. If blocks arrive slower than one every ten minutes, difficulty decreases, indicating that hashrate has left the network. Miners have switched off machines because operating costs exceed revenue or they have found more profitable uses for their power capacity. The current mining capitulation is visible across hashrate, difficulty, miner selling, and hashprice, with surviving miners converting facilities into AI data centers. The economics of mining have deteriorated, causing a meaningful share of the global fleet to shut down while others pivot to alternative revenue sources. This decline has no single policy catalyst, unlike previous drops caused by China's 2021 mining ban or the 2018 bear market contraction. The current contraction results from a lower Bitcoin price, rising energy costs, post-halving revenue compression, and a structural shift in mining business models. After the April 2024 halving, miners receive 3.125 BTC per block, half the reward they earned before, impacting mining profitability.
Metronome Discloses $15.7 Million Synth Shortfall, Blames Oracle Lag in Swap Module
MetronomeDAO revealed a $15.7 million shortfall in synthetic tokens due to delayed price data exploited by trading bots in its swap feature. The shortfall corresponds to about 6,367 msETH and 4.57 million msUSD tokens circulating without collateral backing. This deficit represents roughly 31% of all msETH and 16% of all msUSD tokens in existence, risking losses for liquidity providers. Metronome's swap module allows zero-slippage exchanges between msETH and msUSD, relying on Chainlink's ETH/USD price feed for valuation. Chainlink's price feed updates only when market moves exceed thresholds or after set intervals, causing latency issues in price accuracy. On the Base network, the ETH/USD feed was outside its 0.15% accuracy band 18.5% of all minutes since Metronome's launch there. The feed's response time worsened significantly between March and July 2026, marking the protocol's worst five-month period. Trading bots exploited the lag by swapping synths when the on-chain price lagged behind the real market, gaining value unfairly. Metronome re-priced all 241,292 swaps, totaling $3.6 billion in volume across Ethereum, Optimism, and Base, using exact oracle readings at execution. The protocol's core promise is that every synthetic token is backed by a corresponding debt position with more collateral than its value. Metronome charged swap fees of 0.45% on Base and 0.55% on Ethereum, assuming no bot could profit from price gaps smaller than these fees. The issue was caused by Chainlink price latency at swap execution, a factor Metronome's fee design failed to properly account for, especially on Base.
A major Japanese Bitcoin mining pool just pulled the plug on its Bitcoin service just as 3 mega-miners claimed 60% of the network
A major Japanese Bitcoin mining pool, SBI Crypto, ceased its Bitcoin service as three mega-miners claimed 60% of the network. SBI Crypto's official block list showed July 29 as its latest block, with its share falling from 0.9804% to 0.6192%. By July 31 at about 11:22 UTC, Foundry held 26.67% of attributed blocks, AntPool 17.13%, and F2Pool 16.21%. At the same time, SBI Crypto's share dropped to 0.72%, estimated at 6.8 exahashes per second, reflecting a significant decline. SBI Crypto's seven-day average hashrate fell from 16.222 EH/s on June 30 to 5.817 EH/s on July 30, marking a 64% decrease. The top three pools already held 64.8% of the network in the July 20 weekly bucket, prior to SBI's cutoff. Aggregate pool records do not reveal where SBI Crypto's lost hashrate was redirected after the shutdown. SBI Crypto scheduled a full Stratum shutdown by 23:59:59 UTC, with its website remaining open for historical data and payout status. The final payout schedule and the end dates for API and portal access were not specified following the shutdown announcement. Later on July 31, a Hashrate Index reading showed Foundry USA, AntPool, and F2Pool collectively held 60% of recent blocks. Weekly data indicated a more complex distribution of hashrate, with some pools like Luxor rising and others like Braiins falling. Bitcoin's market dominance stands at 58.51%, with the total crypto market valued at $2.14 trillion and $36.93 billion in 24-hour volume.
