Bitcoin ETFs see scrutiny as Avenir 13F shows IBIT stake

Did Avenir keep IBIT unchanged? Latest filings suggest no

Recent headlines suggested avenir group left its iShares Bitcoin Trust (IBIT) stake unchanged. A review of the latest 13F-linked disclosures indicates the position instead increased across 2025.

By March 31, 2025, Avenir Group IBIT holdings reached about 14.7 million shares, valued near US$691 million, up from 11.3 million at end-2024, as reported by Weex. The figures show active accumulation rather than stasis.

By September 30, 2025, the disclosed stake was 18,297,107 IBIT shares, or roughly US$1.189 billion, as reported by Cointime. The trajectory contradicts the notion that Avenir kept IBIT “unchanged.”

Overall, the data depict an upward allocation path through 2025, with later-quarter stabilization better explained by filing timing and valuation conventions than by a static policy.

Why Avenir’s IBIT allocation matters for institutions

IBIT accumulation by a large allocator is a signal of durable demand for regulated spot Bitcoin exposure. For institutions, it informs liquidity access, operational fit with custodial rails, and portfolio construction around digital-asset beta.

“PANews reported on February 14 that Avenir Group disclosed that it held 18,287,323 shares of BlackRock IBIT in Q4 2025,” as reported by PANews. This suggests a large, steady position after a multi-quarter build.

Earlier in the adoption cycle, approximately US$384 million in Bitcoin ETFs appeared in a 13F filed August 2, according to the U.S. Securities and Exchange Commission (SEC). That early sizing helps contextualize subsequent scale-ups.

At the time of this writing, IBIT last closed at 38.29 and traded at 38.56 after-hours, based on data from NasdaqGM. This market color is descriptive context, not forward-looking guidance.

Immediate impact: verification steps and reporting-lag context

For readers reconciling headlines with filings, start by comparing the most recent quarter’s 13F line items to third‑party summaries, then align share counts and reported values by quarter‑end date.

SEC 13F filings are backward‑looking, reflect U.S.-listed positions only, and value holdings at the quarter’s final trading day. Moves after quarter‑end, and before the filing deadline, do not appear in that report.

Apparent discrepancies between preliminary coverage and filed data often stem from this timing gap, different valuation timestamps, or naming conventions for ETF tickers in portfolio reports.

Where to verify Avenir’s IBIT in SEC 13F

Consult the firm’s Form 13F for the relevant quarter and locate the iShares Bitcoin Trust (IBIT) entry. Confirm the reported share count and market value stated for the quarter‑end date.

How 13F timing and valuation affect interpretation

Form 13F captures a point‑in‑time snapshot at quarter‑end and covers U.S.-listed securities. Because reporting is delayed, interim trading activity is not reflected, and valuations mirror the specific quarter‑end pricing.
