Monthly Crypto Roundup by CoinsDo: May 2026
May 2026 was a month where the policy machinery kept moving and the price action stopped cooperating.
Bitcoin posted its first negative month since February, ETF flows reversed in record fashion, and Ethereum broke below $2,100 for the first time in 2026. But the regulatory calendar delivered more in four weeks than it had in the previous twelve: the Clarity Act passed Senate Banking Committee, the CFTC opened the door to US-regulated perpetuals, and SoFi became the first national bank to put a stablecoin directly into a retail banking app.
The split is the story.
Market Performance
Bitcoin opened May around $77,000, climbed above $80,000 by mid-month, and gave most of it back. By May 29 it was trading near $73,500, finishing the month down about 4.5% and ending a two-month winning streak.
Ethereum had a worse run. After holding $2,100 for three consecutive weeks, it broke through on the third test and closed near $2,075, down 12.6% — its worst May since 2022 and a sharp break from the +24.7% gain it posted in May 2024 and +41.1% in May 2025. Solana relatively outperformed at -2.1%.
The unusual feature was the divergence with US equities. The S&P 500 cleared 7,568 in late May, posting record highs, while spot Bitcoin ETFs logged their longest sustained redemption streak ever. Risk assets rallied; crypto sold off.
Points of Interest
- Bitcoin ETF outflows hit a record nine-day streak with $2.8 billion drained
Between May 15 and May 28, US spot Bitcoin ETFs recorded nine consecutive trading days of net outflows totalling approximately $2.8 billion — the longest withdrawal streak since the products launched in January 2024. Extended through May 30, Decrypt put the cumulative figure near $2.97 billion across 10 sessions. BlackRock's iShares Bitcoin Trust accounted for roughly $2.04 billion of the outflow, including a $527.8 million withdrawal on May 27 — IBIT's second-largest daily outflow on record. For the month overall, crypto.news reported $2.43 billion in net outflows, the largest monthly withdrawal of 2026 and a dramatic reversal from April's $1.97 billion in inflows. Ethereum ETFs lost roughly $401.6 million for the month, ending the brief positive run.
- The Clarity Act cleared Senate Banking Committee in a 15-9 vote
On May 14, the Senate Banking, Housing, and Urban Affairs Committee voted 15-9 to advance H.R. 3633, the Digital Asset Market Clarity Act of 2025, sending the first comprehensive Senate crypto market structure bill to the floor; analysis via Troutman Pepper). Two Democrats — Senators Angela Alsobrooks and Ruben Gallego — crossed over to support the bill, with Alsobrooks playing a leading role in shaping the compromise language on stablecoin yield.
The committee moved despite a formal rejection of the Tillis-Alsobrooks stablecoin compromise on May 9 by the three largest US banking trade groups — the Independent Community Bankers of America, the Bank Policy Institute, and the American Bankers Association— which warned that activity-based rewards on stablecoins would erode bank deposit funding. A floor vote remains the next hurdle, with several committee members signalling they would seek further changes on illicit finance and ethics before voting yes.
- The CFTC approved the first US-regulated Bitcoin perpetual futures
On May 29, the CFTC issued an Order for Approval to KalshiEX to list BTCPERP — the first true perpetual contract (no fixed expiration) on a US-regulated exchange. The same day, the CFTC issued a no-action letter clearing Coinbase Financial Markets to route US customers to Deribit perpetuals through Coinbase Bermuda, with Bitcoin, ETH, and stablecoins eligible as margin collateral. Perpetual futures account for roughly 78% of global crypto derivatives volume — around $85.7 trillion in 2025 — almost all of it offshore. Bringing them onshore is the regulatory shift that has been waiting in the wings for years.
- SoFi launched the first US national bank stablecoin on a retail banking app
On May 27, SoFi rolled out SoFiUSD to its nearly 15 million members, becoming the first US national bank to offer a stablecoin directly to retail customers on a public blockchain. The token is dollar-backed, redeemable 1:1 through SoFi Bank, and operates on Ethereum and Solana.
SoFi also announced plans to build a mechanism for converting SoFiUSD balances into tokenized deposits that may qualify for FDIC insurance and earn interest, and to list SoFiUSD on Bullish for institutional trading.
As Loeb & Loeb noted in their analysis, the mechanic — non-yield-bearing payment stablecoin for movement, yield-bearing tokenized deposit for storage, conversion between — is the first practical implementation of both halves of the GENIUS Act framework.
- Paxos won SEC approval as the first blockchain-native clearing agency for US equities
On May 28, the SEC granted Paxos Securities Settlement Company full registration as a clearing agency under Section 17A, making it the first blockchain firm authorized to operate as a central securities depository for traditional equities in the US — positioning it alongside legacy post-trade frameworks like the DTCC.
The approval is the result of seven years of engagement with the SEC, beginning with a 2019 no-action letter and a 2020 settlement pilot that processed equity trades for AT&T and General Electric. Same-day or near-instant settlement of US stock transactions on blockchain rails is no longer a thesis. It is registered infrastructure.
- Crypto hacks dropped 90% from April's $651 million to roughly $68 million
After April's worst-month-since-2022 figure, May was the third month of 2026 with under $100 million in crypto-related losses. CertiK confirmed approximately $68.3 million lost across exploits, scams, and security breaches, with about $2.6 million attributed to phishing.
PeckShield's parallel count put the figure at $81.7 million across 40 incidents — an 87.4% month-on-month decrease. The largest single event was an $11.5 million exploit on the Verus Protocol cross-chain bridge on May 18, followed by THORChain at roughly $10.1 million.
Cross-chain bridges still accounted for $28.6 million or about 42% of CertiK's monthly total. The structural vulnerability that drove April's catastrophe is unchanged, just less actively exploited.
Macro Backdrop
April CPI, released May 12, came in at 3.8% year-over-year — the highest reading since May 2023 — with energy up 3.8% for the month and accounting for over 40% of the headline gain
Gasoline was up 28.4% annually, and the ongoing US-Iran conflict — now in its third month — continues to feed the energy line. Rate-cut expectations have collapsed, with traders now pricing virtually no cuts through the end of 2027.
The Fed held at 3.5-3.75% at its late-April meeting and did not meet in May. Jerome Powell's chairmanship ended May 15, though he plans to stay on as governor with his term running through early 2028.
The macro backdrop explains the ETF outflows more cleanly than any crypto-specific narrative. With US equities at record highs and rate cuts off the table, institutional capital rotated into equity momentum rather than Bitcoin.
Final Thoughts
April felt like a month where the institutional story got stronger and the security story got harder. May was the opposite on both counts.
The security improvement was real. $68 million against April's $651 million is not a rounding error. But the institutional story took a sharp step back. $2.8 billion in nine days is the largest sustained ETF redemption since the products launched, concentrated in BlackRock's flagship, against a backdrop of equity markets making new highs without crypto.
The regulatory wins were genuine. A Senate Banking markup, the first US-regulated perpetuals approval, a national bank stablecoin in a retail app, and a blockchain-native clearing agency at the SEC — any one of these would have been a notable month. All four in four weeks is the kind of policy progress the industry has been chasing for two years.
The disconnect is what makes the month worth paying attention to. The infrastructure under crypto kept getting more regulated, more bank-grade, more integrated with traditional finance. The price action acted like none of it mattered. Both can be true at the same time, but they usually aren't for long.
