When members of Congress trade stocks, people tend to watch closely. Sometimes they're looking for conflicts of interest—a lawmaker on the banking committee buying bank stocks right before a key vote, that sort of thing. Other times, the story is just about the trade itself: what they bought, when they bought it, and for how much.

This story is a bit of both.

Congresswoman Sheri Biggs (R-S.C.) recently filed her periodic transaction report, and it shows she—or more precisely, her spouse through a professionally managed account—bought between $100,000 and $250,000 worth of the iShares Bitcoin Trust (IBIT) on March 4, 2026.

This wasn't her first dip into the Bitcoin ETF pool. She disclosed an identical-sized purchase of IBIT back on July 9, 2025. So, she's essentially doubling down.

The timing of the March buy is interesting from a market perspective. Bitcoin was in a bit of a slump in early 2026. On the day of the trade, March 4, it was bouncing between $67,437.41 and $74,051.80. As of today, it's trading around $77,238.50. So, if you're scoring at home, that's a trade that's currently in the green. It looks like buying a dip, and so far, it's working.

From a conflict-of-interest standpoint, this trade is arguably less eyebrow-raising than some others. Biggs sits on the Foreign Affairs, Homeland Security, and Science, Space and Technology committees. She's not on the Financial Services Committee or any panel directly crafting crypto legislation. Her committee assignments don't scream "insider info on Bitcoin ETFs." The red flags here are less about policy access and more about the sheer scale of her trading activity and her past reporting habits.

And that's where the story gets a little stickier.

Biggs has been flagged before for late disclosures. Her July 2025 purchase of IBIT was reportedly filed past the legal deadline set by the STOCK Act, the law designed to prevent congressional insider trading by requiring timely reporting. As the data firm Quiver Quantitative pointed out at the time, "We just came across new STOCK Act violations. Representative Sheri Biggs filed dozens of trades made past the reporting deadline. Her husband bought up to $250K of Bitcoin, $IBIT, on July 9th. Pro-crypto legislation was passed a week later."

The trades are made by her husband and portfolio managers, which Biggs could argue means she wasn't personally directing each trade. But the law is clear: the responsibility for reporting on time still falls on the member of Congress.

This latest IBIT purchase is just one line in a much larger ledger. According to data from Quiver Quantitative, Biggs and her family have disclosed a total of $11.27 million in transactions over time, buying and selling stocks, ETFs, debt securities, and corporate bonds. So far in 2026, she's reported $487,000 in transactions. Most of her recent disclosures are for corporate or government debt, not individual stocks. Her last disclosure for individual company stocks was back in March 2025. The data also estimates her net worth at $15.3 million.

So, what's the takeaway? You have a congresswoman with substantial wealth, engaged in active securities trading through managed accounts. She's shown a specific, repeated interest in a Bitcoin ETF, buying it again when the price was down. And she has a history of filing the paperwork for these trades late.

It's less a story about a single trade and more a profile of how a modern member of Congress navigates—and sometimes stumbles over—the rules governing their own financial portfolios.
