Spot Bitcoin ETFs did more than open retail access. They created a clean benchmark that forces every Bitcoin-linked equity to justify itself. Once IBIT, FBTC, and ARKB existed, the question for $MSTR, $MARA, $RIOT, $CLSK, and $COIN became sharp: what are you adding that the wrapper does not already deliver?
The answer is different for each ticker, and the filings show why.
Start with $MSTR. The company disclosed aggregate fair market value of approximately $64.04 billion as of April 26, 2026, at $78,258 per BTC, per the May 5 10-Q. Operating revenue ran at $354.25 million for the period ending September 30, 2025. The Bitcoin position dwarfs the software business by more than two orders of magnitude. $MSTR is a capital allocation vehicle for accumulating Bitcoin at a scale retail cannot replicate. The dominant variables are Bitcoin price, capital markets access, and the premium or discount the equity trades to net asset value. The software revenue is an accounting artifact.
The Wrappers Solve Custody, Not Analysis
IBIT, FBTC, and ARKB exist to pass Bitcoin price through with minimal friction. All three carry a BTC Exposure Score of 90. Filing footprints are thin because there is no operating business to disclose. Event Momentum sits at the floor for all three, reflecting no earnings, no production updates, no capital raises, and no insider transactions to generate filing density.
The variables that matter for these wrappers are AUM, flows, trading liquidity, and premium or discount to net asset value. None of those variables appear in the equity filings of $MSTR, $MARA, or $COIN.
The IBIT versus $MSTR price gap makes the point. Over the 30 days ending May 15, 2026, IBIT gained approximately 5.3%. $MSTR gained approximately 23.6%. That 18-point spread is not alpha. It is operating leverage, financing activity, and a shifting market appetite for the premium-to-NAV trade layered on top of the same underlying Bitcoin move.
Miners Trade On Operations, Not Just Price
$MARA, $RIOT, and $CLSK hold Bitcoin, but the Bitcoin is an output of mining operations, not the thesis. $MARA disclosed approximately $2.41 billion in aggregate fair market value as of March 31, 2026, per the May 10 10-Q. $RIOT disclosed approximately $1.07 billion as of March 31, 2026, per the April 29 10-Q. $CLSK disclosed approximately $813.22 million as of March 31, 2026, at $68,222 per BTC, per the May 10 10-Q. Real positions. But not the equity story.
The equity story runs through production. $MARA reported revenue of $174.61 million for the period ending March 31, 2026. $RIOT reported $167.22 million for the same period. $CLSK's latest loaded revenue was $766.31 million for the period ending September 30, 2025. Those lines reflect hashrate, energy cost, fleet utilization, and post-halving margins. A miner with expensive power and aging ASICs underperforms a miner with cheap power and modern fleet hardware even when Bitcoin rallies.
The 90-day performance dispersion through May 15, 2026 makes that concrete. $RIOT gained approximately 54%. $MARA gained approximately 57%. $CLSK gained approximately 33%. All three sit in short-term uptrends, but only $RIOT carries a long-term uptrend classification. Three miners, nominally the same Bitcoin exposure, 24 points of spread between best and worst over 90 days. That is operating divergence, not Bitcoin divergence.
COIN Is A Volume Business First
Coinbase is the hardest ticker to slot. It is an exchange, a custodian, a staking provider, and increasingly a financial infrastructure business. Revenue for the period ending March 31, 2026, was $1.41 billion. Bitcoin exposure runs through transaction revenue, custody fees, and modest holdings, but trading volume drives the model.
$COIN's 30-day price change through May 15, 2026, was approximately negative 0.24%, essentially flat, while miners and $MSTR moved sharply. That divergence is the exchange model at work. Near-term revenue depends more on whether people are actively trading than on where Bitcoin settles. A sustained low-volatility Bitcoin environment compresses $COIN's margins without destroying the business, because services and custody revenue provide a floor.
Filing Density Tells You Where Risk Lives
$MSTR's Filing Risk Score sits at 80, driven by ATM programs, convertible notes, and 8-K disclosures from active capital markets work. $RIOT's filing-risk signal is at 90, the highest in this group, reflecting elevated disclosure cadence from capital activity and operational filings. $MARA and $CLSK sit in the elevated range.
IBIT, FBTC, and ARKB all carry filing-risk signals in the watchlist range. The gap reflects what operating companies do: production updates, financing rounds, insider transactions, and risk-factor revisions. Wrappers have almost none of that. Their risk is Bitcoin price risk, full stop.
$COIN sits between the poles. Its Event Momentum is elevated, consistent with regulatory filings, earnings disclosures, and product announcements that come at the pace of an active operating business. Exchange filing cadence looks different from miner cadence, and both look different from a treasury holder's.
Each Category Fails Differently Under Stress
A Bitcoin drawdown hits all four categories, but the transmission path differs. ETF wrappers transmit the drawdown directly and proportionally. $MSTR amplifies the drawdown through leverage and the collapse of any premium to NAV. Miners watch revenue per block compress while fixed energy costs hold, squeezing margins and sometimes forcing balance-sheet Bitcoin sales. $COIN sees trading volume fade and transaction revenue with it, partially offset by custody and services.
Recovery diverges the same way. Miners recover when Bitcoin price rises and energy stays contained. Treasury holders recover when Bitcoin price rises and capital markets stay open for new financing. Exchanges recover when volatility and volume return, regardless of Bitcoin direction. ETF wrappers recover when Bitcoin recovers.
The Other Reading
The strongest objection: Bitcoin dominance sat at 58.2% on May 18, 2026, with a crypto Fear and Greed reading of 28, classified as fear. When fear dominates and Bitcoin leads the tape, correlations across wrappers, miners, treasury holders, and exchanges compress toward 1. Everything sells together. In that regime, the category framework here looks academic. A trader getting dumped out of $RIOT and IBIT on the same day does not care about hashrate margins versus expense ratios.
The objection is real, but it does not undermine the framework. Correlation compression during stress is a feature of every sector. Equity correlations rose to nearly 1 across megacap tech in March 2020. Nobody concluded that sector analysis was wrong. The point is not that miners and wrappers move independently every day. The point is that the recovery path, the valuation anchor, and the monitoring variables differ. When $RIOT recovers, the question is whether hashrate and energy margins improved. When IBIT recovers, the question is whether flows resumed. When $MSTR recovers, the question is whether the premium to Bitcoin net asset value expanded. Asking the wrong question produces the wrong answer.
The Wrapper Forces The Question
The practical consequence of spot Bitcoin ETF approval is that every other Bitcoin-linked equity now has to justify itself against a clean, low-cost benchmark. For miners, the case is operating leverage to Bitcoin price plus margin discipline. For $MSTR, the case is capital markets velocity and the willingness of the equity market to pay a premium for accumulation at scale. For $COIN, the case is volume, regulatory positioning, and the build-out of services revenue. For IBIT, FBTC, and ARKB, the case is already complete.
The question is now explicit for every operating company: what are you adding beyond the wrapper, and at what cost?
