The U.S. Securities and Exchange Commission is reviewing a proposed rule change filed by Cboe BZX Exchange for six leveraged commodity exchange-traded funds designed to deliver three times the daily performance of their respective benchmarks. The products were launched by Volatility Shares LLC and cover gold, silver, Bitcoin, Ether, crude oil, and natural gas. According to the filing details cited by ChainCatcher, the SEC’s initial review period runs for 45 days after publication in the Federal Register. The Bitcoin and Ether funds would invest primarily in front-month and second-month futures contracts listed on the Chicago Mercantile Exchange rather than holding spot Bitcoin or Ether directly. They would also hold cash and cash equivalents for collateral or margin purposes. Before any of the funds can list, the SEC must approve the exchange’s proposed rule change, and the trusts’ Form S-1 registration statements must become effective. Each fund must have at least 100,000 shares outstanding at listing, and authorized participants would be able to create or redeem shares in cash in blocks of 10,000.

The U.S. Securities and Exchange Commission is reviewing a proposed rule change filed by Cboe BZX Exchange for the listing of six leveraged commodity exchange-traded funds that aim to deliver three times the daily performance of their underlying benchmarks. The products, sponsored by Volatility Shares LLC, cover gold, silver, Bitcoin, Ether, crude oil, and natural gas. According to the filing details cited in the report, the SEC’s initial review period runs for 45 days after publication in the Federal Register. The funds are structured to operate as commodity pools rather than investment companies. For the Bitcoin and Ether products, the investment strategy would focus primarily on front-month and second-month futures contracts traded on the Chicago Mercantile Exchange, instead of holding spot Bitcoin or Ether directly. The funds would also hold cash and cash equivalents for collateral or margin purposes. Before any of the products can begin trading, the SEC must approve the exchange’s proposed rule change, and the trusts’ Form S-1 registration statements must become effective. Each fund would also need to launch with at least 100,000 shares outstanding, while authorized participants would be allowed to create or redeem shares in cash in blocks of 10,000.

The week of Aug. 17-23 is packed with events that could draw close attention from crypto traders, policymakers, and market infrastructure operators. On Aug. 19, President Donald Trump is expected to attend a White House gathering of crypto and prediction-market executives, with CEOs from Coinbase, Ripple, Gemini, Robinhood, Polymarket, and Kalshi also set to join, according to CoinDesk. The event is expected to warm up the first formal meeting of the U.S. Commodity Futures Trading Commission’s newly formed Innovation Advisory Committee. A day later, the Federal Reserve will release minutes from its July policy meeting, where the Federal Open Market Committee voted 9-3 to keep the federal funds rate at 3.5% to 3.75%. Markets will be looking for clues on how many officials saw a case for a rate hike and what evidence could shift the broader committee. Elsewhere, South Korea will roll out tighter rules for single-stock leveraged products and expand review standards for crypto operator registration. The same week also includes a series of exchange and network updates, including Binance delistings and precision changes, Coinbase product launches and support changes, Upbit service suspensions, a planned bitcoin eCash hard fork, and Manus data migration steps tied to its return as an independent company.

UBS reported a sharp increase in call-option exposure tied to BlackRock’s spot Bitcoin ETF, iShares Bitcoin Trust (IBIT), in its latest 13F filing. As of June 30, the number of underlying shares represented by the bank’s IBIT calls rose from 80,000 in March to 1.95 million, a jump of about 2,338%, or roughly 24 times in one quarter. Over the same period, UBS’s non-option IBIT holdings increased 11.94% to 407,900 shares, while its put exposure fell from 303,300 shares to 143,300, a decline of 52.75%. The report said UBS’s total IBIT position was worth about $90 million, up roughly 230% in the first half of the year. The filing, however, does not reveal whether those positions were held for clients, market making, hedging, or the bank’s own directional view, making any straightforward bullish interpretation incomplete.

Hedge fund manager Paul Tudor Jones increased his stake in BlackRock’s spot Bitcoin ETF in the second quarter after spending the past year selling, while sharply reducing his call option exposure on the same fund. According to CoinDesk, citing a 13F filing, Jones’ Tudor Investment raised its holdings in iShares Bitcoin Trust (IBIT) to 688,529 shares, worth about $22.9 million as of June 30. That marked an increase of 109,446 shares from the previous quarter, or 18.9%. At the same time, the firm cut its IBIT call position by 85.2%. The number of underlying shares tied to those calls fell from 998,000 in March to 148,000. The shift indicates a move away from using options to express a bullish view and toward holding the spot ETF directly. Even so, the position remained relatively small. The report said the stake was still 91.4% below its 2024 peak and accounted for about 0.03% of Tudor’s reported 13F securities. ABMedia also noted that Jones has long viewed Bitcoin as a hedge against inflation, and the latest portfolio adjustment was consistent with that stance.

Harvard University’s endowment kept its position in BlackRock’s spot Bitcoin ETF, the iShares Bitcoin Trust (IBIT), unchanged in the second quarter, according to its latest 13F filing. As of June 30, the fund held 3.0446 million IBIT shares worth about $101.4 million, the same share count reported at the end of the first quarter, halting two straight quarters of reductions. The filing shows Harvard had cut the position by 21% in the fourth quarter of 2025 and by another 43% in the first quarter of 2026. IBIT now accounts for roughly 2.4% of Harvard’s disclosed $4.26 billion U.S. equity portfolio. The endowment’s gold exposure remained larger, with holdings in iShares Gold Trust and SPDR Gold Trust totaling about $171.2 million. Harvard had already exited BlackRock’s spot Ether ETF position valued at $86.8 million and added no new Ethereum-related exposure in the second quarter. The filing also shows SpaceX as Harvard’s largest single stock holding at 12,935,100 shares worth $2.21 billion, or about 52% of its roughly $4.3 billion disclosed U.S. stock assets. Other institutions reported mixed IBIT activity, with Mubadala and the Abu Dhabi Investment Council unchanged, JPMorgan increasing its position, and Morgan Stanley trimming its stake.

Harvard University’s endowment stopped cutting its position in BlackRock’s iShares Bitcoin Trust (IBIT) in the second quarter, according to its latest 13F filing cited by The Block. The filing shows Harvard Management Company held 3,044,612 IBIT shares as of June 30, valued at $101.4 million, unchanged from the prior quarter after two straight quarters of selling. The endowment had reduced the position by 21% in the fourth quarter and by another 43% in the first quarter. IBIT ranked 11th among Harvard’s 19 disclosed holdings and accounted for 2.4% of its $4.26 billion portfolio. The filing also showed that Dartmouth College made no changes to its three crypto ETF positions, while their combined value fell from $14.6 million to $12.4 million during the quarter. Abu Dhabi sovereign wealth fund Mubadala likewise kept its IBIT stake unchanged at 14,721,917 shares worth $490.1 million, making it the second-largest holding in its 13F portfolio.

Solana recorded about $5.8 billion in tokenized stock spot DEX trading volume in the second quarter of 2026, up 114% from the previous quarter, according to Techub, citing CryptoBriefing. The figure marked a record high for the category. Backed Finance’s xStocks suite was identified as the main driver of the increase, offering tokenized assets pegged 1:1 to U.S. stocks and ETFs. Raydium emerged as the leading venue for trading these assets, with cumulative volume surpassing $3 billion as of June 27. During the second quarter, Solana accounted for roughly 95% to 97% of global tokenized stock DEX trading volume. The report also noted a shift after the quarter ended: Robinhood Chain began to overtake Solana in daily trading volume in late July. The data points to Solana’s dominance in tokenized equity trading on decentralized exchanges during Q2, while also showing that competition picked up heading into the third quarter.
