Nasdaq has filed for crypto asset manager 21Shares to list a spot Sui exchange-traded fund (ETF) in the US, initiating the Securities and Exchange Commission’s review process.

The stock market’s May 23 19b-4 filing, which asks the SEC to list the 21Shares SUI ETF, follows 21Shares’ April 30 submission of its S-1 registration statement to the SEC, which asked the regulator to approve trading of the proposed fund.

Both regulatory filings are needed for the Sui (SUI) tracking fund to gi live, with the 19b-4 filing kicking off the SEC’s review process. The agency must decide whether to accept, reject or delay the application within 45 days and it can delay its decision multiple times, for a maximum review period of 240 days.

The SEC must decide on 21Shares’ application by Jan. 18, 2026, at the latest.

21Shares proposed BitGo and Coinbase Custody as the custodians to hold SUI on behalf of the trust, however, the filing did not include details on a management fee or ticker.

Canary Capital is the only other asset manager that has submitted 19b-4 and S-1 filings to list a spot Sui ETF, filing the forms on April 8.

21Shares said in its 19b-4 filing that the SUI token powers the Sui network and serves four main purposes: it can be staked to earn rewards, used to pay gas fees, function as a liquid asset for Sui applications and serve as a governance token.

The Sui ecosystem is largely focused on decentralized applications and has been dubbed a potential Solana killer.

SUI is the 13th-largest cryptocurrency, but its $12.3 billion market cap remains a fraction of Solana (SOL)’s $92 billion market cap, according to CoinGecko.

21Shares aims to add to SUI offerings

21Shares already lists a Sui exchange-traded product in Europe, on the Euronext Paris and Euronext Amsterdam stock exchanges.

Those listings have contributed to SUI-based exchange-traded products having $317.2 million in assets under management (AUM), according to a May 26 report from CoinShares.

Flows into SUI ETPs increased by $2.9 million between May 16 and May 24, and only trails Bitcoin (BTC), Ether (ETH), Solana and XRP (XRP) in terms of net assets.

A third individual, suspected of being connected to the recent kidnapping, torture and attempted extortion of an Italian tourist in New York City, surrendered to law enforcement on May 27.

33-year-old William Duplessie was taken into custody by the New York Police Department (NYPD) and will be charged with “kidnapping and false imprisonment of an associate,” NYPD Commissioner Jessica Tisch said.

The incident comes amid a string of kidnappings and ransom attempts targeting crypto investors and their loved ones, prompting additional security measures from investors and industry executives.

According to reporting from The New York Times, Duplessie and crypto investor John Woeltz, who was previously arrested by police in connection with the case, both had connections to an NYC-based crypto hedge fund.

Duplessie negotiated his surrender with the NYPD over the course of several days leading up to his arrest.

Italian tourist kidnapped and drugged in an attempt to steal crypto

Michael Valentino Teofrasto, a 28-year-old Italian tourist in New York City, was kidnapped in Manhattan and held captive for weeks before managing to escape and alert law enforcement authorities.

Teofrasto said the suspects bound him, stole his passport and mobile device, and subjected him to physical beatings, which included being shocked with a Taser.

The victim also said the suspects repeatedly hit him with a firearm and would submerge his feet in the water while tasing him in an attempt to get him to reveal his crypto private keys.

The tourist was reportedly held in a luxury townhome in the SoHo neighborhood of Manhattan and escaped the luxury townhome where he was being held.

Once free, Teofrasto flagged down a police officer and relayed the kidnapping incident to the official.

Following his incident report, NYC police arrested crypto investor John Woeltz and charged the investor with kidnapping for ransom and three other felony counts.

Woeltz is expected to appear in court for an additional hearing on May 28 and is currently being held in custody without bail while awaiting trial.

Key takeaways:

SharpLink Gaming establishes the first ETH treasury, backed by Ethereum co-founder Joe Lubin. SharpLink will invest $425 million to acquire 120,000 ETH.

Ethereum futures open interest hits an all-time high of $36.1 billion, with ETH price climbing 4.5% on the daily chart.

Nasdaq-listed SharpLink Gaming (SBET) announced a $425 million private investment in public equity (PIPE), acquiring approximately 69.1 million shares at $6.15 each to establish the first Nasdaq-listed Ethereum (ETH) treasury company.

Spearheaded by Ethereum co-founder Joe Lubin, this move mirrors Strategy’s (MSTR) successful Bitcoin treasury strategy, which has yielded over $8.2 billion in gains in 2025, by leveraging stock and bond sales to acquire BTC.

Former Ethereum core developer and contributor Eric Conner highlighted the bullish implications of SharpLink’s move, noting its potential to create a “public ETH proxy for funds that can’t hold tokens directly.” 

Conner emphasized that the acquisition of 120,000 ETH — likely to be staked — could lead to “supply compression” by removing tokens from circulation. The Ether proponent also pointed to the “new narrative fuel” this provides, positioning ETH as a “digital reserve collateral” and potentially driving its adoption on mainstream balance sheets through an equity wrapper like $SBET.

However, crypto analyst VICTOR cautioned against over-enthusiasm, outlining the risk of leveraging gains from an altcoin still down 19% in 2025. 

In Q1 2025, Cointelegraph reported a sharp decline in Ethereum network fees, dropping to $605,000 from $2.5 million in just two weeks in March, alongside a noticeable decrease in decentralized app (DApp) activity. Although average daily fees on the Ethereum chain have stayed above $1 million since May 9, 2025, fees remain significantly lower compared to Q1 2024, as highlighted in the chart.

The SharpLink announcement triggered a surge in Ethereum futures market activity. Ether futures open interest (OI) hit a new all-time high of $36.1 billion, increasing $3.5 billion in 24 hours. Ether OI has increased by 72% over the past month, reflecting heightened trader activity.

Ether prices are also up 4.50% for the day, and Maartuun, a community analyst at CryptoQuant, indicated the likelihood of a leveraged-fueled pump for the altcoin. 

Over the past 30 days, Ether prices have gained 48%, with the markets exhibiting 10 leverage-driven pump signals. The majority of these rallies — eight out of 10 — resulted in negative returns, while one rally triggered a short squeeze, driving prices higher, and another displayed neutral price action.

From a technical perspective, Ether’s price action on the daily chart posted a descending triangle, a bullish breakout pattern, which creates equal highs and higher lows, converging toward an imminent rally. 

The pattern is bordered by two trendlines, the upper resistance, currently around $2,700 and the ascending support line. A bullish breakout above $2,677 targets the pattern’s measured move, calculated by adding the triangle’s height to the breakout point. This projects a target range of $3,100–$3,200, aligning with prior resistance levels around $3,100 and $3,400.

The relative strength index (RSI) at 68.50 supports this bullish outlook. An RSI near 70 indicates strong momentum, with the indicator resetting after oscillating in the overbought region (above 70), suggesting the altcoin could be gearing up for a fresh rally. 

Anonymous crypto trader mo_xbt pointed out a “sandwich setup” for Ethereum. The analyst also believed that a $3,000 retest was imminent and said,
