The former head of the Commodity Futures Trading Commission will leave the Blockchain Association after the vote on the Crypto-Asset Market Clarity Act fails.

The Blockchain Association said Friday that Summer Mersinger, a former commissioner of the US Commodity Futures Trading Commission, will step down as chief executive officer on October 16 and leave the advocacy organization at year’s end. The announcement comes after one of the group’s legislative priorities suffered a significant setback in Congress.

Leadership returns to a familiar name

Kristin Smith, the Blockchain Association’s former chief executive, will return as interim CEO when Mersinger steps down. Mersinger joined the association in June 2025 after leaving the Commodity Futures Trading Commission three years before her second term as commissioner was scheduled to end.

Mersinger described her move from the commission to the industry association as an effort to build a unified case for clear rules in Washington. She said she came from the Commodity Futures Trading Commission because she believed the industry deserved clear rules of the road and a credible, unified voice making the case for them. The association highlighted her work advancing the Guiding and Establishing National Innovation for US Stablecoins, or GENIUS Act, and helping provide regulatory clarity at the Securities and Exchange Commission and the Commodity Futures Trading Commission.

The Senate bill that stalled

The organization did not mention the Digital Asset Market Clarity Act in its announcement about the leadership change, even though the measure has been under consideration in the Senate and the Blockchain Association repeatedly urged lawmakers to support it.

Earlier this month, the Digital Asset Market Clarity Act failed to gain enough votes from Democrats and Republicans in a cloture motion. A cloture motion is a procedural step used in the Senate to end debate and allow legislation to advance. Many experts expect the bill to remain in limbo until 2027.

What the transition means for policy watchers

For readers tracking crypto legislation, the leadership change shows how a stalled bill can reshape an advocacy organization’s next chapter. The Blockchain Association did not immediately respond to questions about Mersinger’s plans for 2027. The immediate question is whether the association will keep its focus on stablecoin rules and regulatory clarity while the Digital Asset Market Clarity Act remains unresolved.

Separately, the Commodity Futures Trading Commission issued a warning over risky prediction market “mention” contracts. The warning shows that regulators are still examining new digital-asset products while Congress remains divided over broader market legislation.
