Abstract

ProShares' GENIUS Money Market ETF (IQMM) shattered records with an "insane" $17 billion in first-day trading volume, far surpassing the debut of major Bitcoin ETFs. The fund, designed to hold assets compliant with the proposed U.S. stablecoin (GENIUS Act) regulations, is intended for use as reserves by stablecoin issuers. While speculation suggested a major issuer like Circle could be behind the volume, it was clarified the initial funding came from internal ProShares funds for cash management. Separately, the stablecoin sector received a significant regulatory boost as the SEC reduced its capital "haircut" on stablecoin holdings from 100% to 2%, a move hailed by Circle's CEO as a major win that will foster greater adoption in capital markets.

A money market fund targeting issuers regulated under the U.S stablecoin law, GENIUS Act, has made a new record for debut trading volume.

The ProShares GENIUS Money Market ETF (NYSE: IQMM) saw a whopping $17 billion in trading volume.

For context, BlackRock’s iShares Bitcoin ETF (IBIT) saw $1 billion in day-one volume, while its other product, the BlackRock ESG ETF, saw $2 billion.

This was eight times the previous record, noted Bloomberg ETF analyst Eric Balchunas.

He added,

“Insane: That $17B is going to show up as flows/assets tonight. Where is $ coming from? Either way, I was wrong about this ETF.”

Is Circle behind the record debut?

Responding to Balchunas, another ETF expert, Nate Geraci, speculated,

“Would assume ProShares cut a deal with one of the major U.S.-based stablecoin issuers...Looking at assets, believe that would only leave Circle.”

But Ben Johnson, head of client solutions at Morningstar, clarified that the product was funded by other ProShares funds for easier cash management purposes.

So, why GENIUS Act-inspired? The U.S stablecoin law has several instruments that can be used as reserve assets for issued stablecoin tokens. Some of the permitted reserves include cash and cash equivalents, short-dated U.S. Treasury bills, and money market funds focused on cash management.

This makes it easier to redeem and to cater to rising demand if users cash out en masse from stablecoins into fiat without triggering a bank run or risking broader financial markets.

And that’s where the ProShares ETF falls: an MMF focused on stablecoin reserves, likely in the hope that issuers may opt for it for easier cash management, too. It’s unclear whether it will attract these potential issuers.

Why the SEC’s 2% ‘haircut’ is good for stablecoins

Meanwhile, the stablecoin sector got another win after a recent SEC guideline. The regulator said payment stablecoin will now have 2% haircut, similar to money market funds.

In the past, stablecoins had a 100% ‘haircut’, meaning holding them had no capital benefit. If you had $100 million, it would be seen as $0 for capital purposes. Now, it can be valued at $98 million.

The change means stablecoin holders can have more trading inventory, loan capacity, and overall financial activity.

For his part, Jeremy Allaire, CEO of Circle, hailed the move as positive for stablecoin adoption.

“This is a big win for USDC adoption in capital markets. Great progress.”


Final Summary

  • ProShares’ GENIUS Act-inspired ETF set a new record, hitting $17 billion in day-one trading volume.
  • Circle CEO hailed the SEC’s 2% haircut for stablecoin as a likely catalyst for USDC adoption.

An Open-Source AI Tool That No One Saw Predicted Kelp DAO's $292 Million Vulnerability 12 Days Ago

An open-source AI security tool flagged critical risks in Kelp DAO’s cross-chain architecture 12 days before a $292 million exploit on April 18, 2026—the largest DeFi incident of the year. The vulnerability was not in the smart contracts but in the configuration of LayerZero’s cross-chain bridge: a 1-of-1 Decentralized Verifier Network (DVN) setup allowed an attacker to forge cross-chain messages with a single compromised node. The tool, which performs AI-assisted architectural risk assessments using public data, identified several unremediated risks, including opaque DVN configuration, single-point-of-failure across 16 chains, unverified cross-chain governance controls, and similarities to historical bridge attacks like Ronin and Harmony. It also noted the absence of an insurance pool, which amplified losses as Aave and other protocols absorbed nearly $300M in bad debt. The attack unfolded over 46 minutes: the attacker minted 116,500 rsETH on Ethereum via a fraudulent message, used it as collateral to borrow WETH on lending platforms, and laundered funds through Tornado Cash. While an emergency pause prevented two subsequent attacks worth ~$200M, the damage was severe. The tool’s report, committed to GitHub on April 6, scored Kelp DAO a medium-risk 72/100—later acknowledged as too lenient. It failed to query on-chain DVN configurations or initiate private disclosure, highlighting gaps in current DeFi security approaches that focus on code audits but miss config-level and governance risks. The incident underscores the need for independent, AI-powered risk assessment tools that evaluate protocol architecture, not just code.
