U.S. Senator Cynthia Lummis of Wyoming has disclosed another bitcoin purchase, revealing that she bought between $50,001 and $100,000 worth of BTC on August 16. According to the filing, bitcoin was trading at roughly $45,000 at the time of the transaction, underscoring that the senator continued to accumulate the asset even after earlier market volatility.
The purchase was reported through a periodic transaction report, or PTR, the disclosure mechanism used by members of Congress to report certain financial transactions. Lummis has built a public reputation as one of the most outspoken bitcoin advocates in Washington, and this latest filing reinforces that image by showing she continues to personally hold and add to her BTC position.
Disclosure Filed After the Reporting Deadline
The filing, however, was submitted outside the 45-day reporting window required under the Stop Trading on Congressional Knowledge Act, better known as the STOCK Act. The law requires members of Congress to disclose purchases and sales of individual stocks, bonds, and commodity futures valued above $1,000 within 45 days of the transaction.
A spokesperson for Senator Lummis’ office said the delay stemmed from a filing error. According to the explanation provided to CNBC, once the issue was identified, the office worked with the Ethics Committee to correct it. The spokesperson characterized the matter as an honest mistake and said it was resolved without penalty.
While delayed congressional financial disclosures often attract public scrutiny, the explanation from Lummis’ office framed the issue as procedural rather than intentional. The available reporting did not indicate any broader enforcement action beyond the corrected filing.
A Longtime Bitcoin Supporter
Lummis has been one of the most consistent pro-bitcoin voices in U.S. politics. Her support for the asset is not new, and it has extended beyond policy rhetoric into her own investment decisions. Earlier in the year, as bitcoin fell below $30,000, she indicated that she intended to buy the dip rather than step back from the market.
At the end of June, she commented publicly on the price decline and said she was excited by the pullback because it created another opportunity to purchase more BTC. That statement now appears to align with her later August transaction, which suggests she followed through on that stance as the market stabilized above prior lows.
Lummis has also said she first bought bitcoin in 2013 at around $330 per coin. As of the end of June, she reportedly held five bitcoins. That historical entry point has often been cited as evidence that her conviction in bitcoin is long-term and predates the recent wave of political and institutional attention around digital assets.
BTC as a Store of Value
Beyond the latest purchase itself, the disclosure is notable because it comes alongside Lummis’ continued framing of bitcoin as a strategic financial asset. In earlier remarks made in February, she said she sees bitcoin as a strong store of value not only for individuals, but also for corporations and governments.
Her most direct argument has been that bitcoin should be considered part of a diversified portfolio. She previously said she still views BTC as an “excellent store of value” and believes it should be part of every individual person’s investment portfolio. That statement places her among the highest-profile elected officials in the United States to make such an unequivocally favorable case for bitcoin ownership.
For market observers, the combination of personal exposure and public advocacy is significant. Unlike officials who comment on digital assets only from a regulatory or macroeconomic perspective, Lummis has repeatedly demonstrated that her support is backed by direct participation in the market.
Why the Purchase Matters
The disclosure offers a window into how some policymakers view bitcoin not merely as a speculative instrument, but as a long-term asset with preservation-of-value characteristics. Lummis’ comments fit within a broader narrative often embraced by bitcoin supporters: that BTC can serve as a hedge against monetary debasement and as a durable asset for long-term holders.
At the same time, the delayed reporting component highlights the continued sensitivity surrounding financial disclosures by elected officials. Even when transactions involve widely discussed assets like bitcoin, transparency and timing remain politically important. In this case, the senator’s office said the matter was corrected and closed without sanctions.
Ultimately, the filing shows two things clearly: first, that Lummis increased her exposure to bitcoin with a purchase valued between $50,001 and $100,000; and second, that she remains firmly committed to the view that BTC deserves a place in mainstream investment portfolios. For supporters of digital assets, that makes her one of the most prominent political advocates for bitcoin adoption in the United States.
