Five of the largest unions in the United States, including the AFL-CIO and the SEIU, sent a joint letter to senators urging them to vote against the Clarity Act. The letter, dated May 10-12, 2026, comes just days before the Senate Banking Committee is scheduled to consider the bill on May 14.
The unions’ main argument: The legislation could jeopardize workers’ retirement savings by opening the door to the infiltration of digital assets into public pensions and 401(k) plans. These accounts collectively hold approximately $39 trillion.
What the Clarity Law Actually Does
The Clarity Act is designed to establish a regulatory framework for crypto markets, governing how digital assets are classified, traded and supervised at the federal level.
Supporters, including Coinbase and other major players in the crypto industry, argue that the bill would support institutional adoption and foster innovation.
Michael Saylor, the Bitcoin evangelist who transformed MicroStrategy into what is essentially a leveraged Bitcoin fund, expressed his support. He views the Clarity Act as an “institutional validation for BTC” and believes it could enable the creation of entirely new yield markets built around digital assets.
Why unions oppose
The letter to senators argues that the Clarity Act allows for “inordinate risks” in digital assets, risks that could ultimately destabilize the economy as a whole for American workers.
The American Bankers Association also expressed concern that the Clarity Act could undermine existing financial protections. When unions and banks agree on something, it’s worth paying attention to. These two groups occupy opposing positions in most political battles.
The broader regulatory standoff
Critics argue the bill goes too far in the other direction. Rather than protecting consumers, they argue that this essentially gives crypto companies a lighter regulatory touch than traditional financial institutions enjoy. This asymmetry, unions warn, could create systemic risks if pension fund managers start investing in digital assets under the new framework.
The timing of the union letter is deliberate. With the committee vote scheduled for May 14, the window to influence senators is narrow.
What this means for investors
If the Clarity Act fails in committee or is significantly amended, expect a period of prolonged regulatory uncertainty. This tends to weigh on both symbolic valuations and the institutional appetite for this space.
The deeper risk is more subtle. If the union-backed opposition succeeds in portraying crypto regulation as a threat to pension security, it will also poison future legislation.
To watch: the committee vote on May 14 is the immediate catalyst. But the real clue will be whether senators who previously supported the Clarity Act will begin to protect their positions in response to pressure from unions.
