The Valkyrie Bitcoin Miners ETF (NASDAQ:WGMI) and the iShares Bitcoin Trust ETF (NASDAQ:IBIT) both market themselves as ways to play Bitcoin, but the past twelve months have exposed how little they actually have in common. With Bitcoin down 43.36% over one year and 30.48% year to date, the simple expectation would be that both funds bled together. Instead, WGMI is up 243.77% over the past year while IBIT is down 43.61%. That gap is the entire story.
What Each Fund Is Actually Betting On
IBIT is the simplest crypto product on the market. 99.93% of the fund sits in spot Bitcoin held through the iShares Bitcoin Trust, with the rest in cash. There is no active management, no equity overlay, no operational complexity. If Bitcoin moves 1%, IBIT moves roughly 1% minus fees. The bet is purely directional on the digital asset itself.
WGMI is something completely different wearing similar branding. It is an actively managed equity basket of Bitcoin mining companies including MARA, CleanSpark, Riot Platforms, IREN, Cipher Mining, Core Scientific, and TeraWulf. These businesses have always carried operational leverage to Bitcoin: they spend dollars on power and hardware, earn coins, and live or die by the spread. But the implicit bet has shifted. Many of the largest WGMI holdings, including Core Scientific, TeraWulf, and IREN, are now repurposing data center capacity to host AI and high-performance computing workloads. That secondary revenue stream is what disconnected the fund from Bitcoin this cycle.
Where The Divergence Shows Up
Year to date, IBIT has tracked Bitcoin almost perfectly, falling 31.78% against Bitcoin’s 30.48% drop. That is exactly the behavior the prospectus promises. WGMI broke the historical pattern entirely, climbing 74.44% YTD as miners signed multi-year AI hosting contracts at margins that dwarf mining economics. Investors who bought WGMI expecting amplified Bitcoin beta accidentally bought an AI infrastructure proxy.
This is the risk hiding inside WGMI: the fund’s returns are now driven by data center deal flow, energy contracts, and equipment financing as much as by Bitcoin. When the AI hosting narrative cools or a single large holding misses on a contract, the same operational leverage that powered the rally will reverse hard. Mining equities have historically exhibited amplified downside relative to Bitcoin during drawdowns, and the April 2024 halving compressed mining margins structurally.
The Practical Comparison
| Factor | WGMI | IBIT |
|---|---|---|
| Exposure | Mining equities + AI/HPC pivot | Spot Bitcoin, 99.93% allocation |
| Expense ratio | ~0.75% | 0.33% |
| 1-year return | +243.77% | -43.61% |
| YTD 2026 return | +74.44% | -31.78% |
| Tax form | 1099 (standard equity) | Grantor trust treatment |
| Single-stock risk | High, concentrated basket | None |
The Verdict
For an investor seeking direct Bitcoin price exposure, IBIT is the cleaner structural fit. It costs 0.33%, tracks the asset cleanly, and carries no company-specific blowup risk. The current Bitcoin price near $60,832 is the only variable that matters.
WGMI is a different product now. It belongs in a portfolio that wants exposure to AI data center buildout dressed in crypto clothing, with the understanding that mining margins remain a swing factor. The 287-percentage-point one-year return gap proves these funds are not substitutes. IBIT fits a bullish Bitcoin view, while WGMI fits a thesis specifically about miners monetizing power and racks for AI workloads, with the understanding that the next reversal in that narrative is likely to be violent.
