Five categories, one investor inbox: the Bitcoin equity universe has fractured

Treating IBIT, $MSTR, $RIOT, and $COIN as interchangeable Bitcoin exposure misreads every position. They sit in four different categories, with four different dominant variables, and the 90-day price tape proves it.

Over the 90 days ending May 18, 2026, $RIOT gained roughly 58%, $CLSK gained about 45%, and $MARA gained around 62%. $MSTR gained 29.5%. The three spot ETF wrappers, IBIT, FBTC, and ARKB, each gained roughly 13 to 14%. $COIN gained 14.1%. The miners delivered three to four times the ETF return. $MSTR delivered roughly double. $COIN matched the wrappers but got there through a completely different mechanism. The divergence is the argument.

The ETF Wrappers Are the Cleanest Signal

IBIT, FBTC, and ARKB do one job: hold Bitcoin and track its price. AUM, flows, trading liquidity, and premium or discount to NAV are the variables that matter. Each carries a BTC Exposure Score of 90, the direct-exposure ceiling, and a low Filing Risk reading consistent with minimal operating complexity. The 30-day and 90-day returns across all three line up within a handful of basis points, which is exactly what wrappers built to replicate the same asset should do.

There is no operating leverage amplifying the move in either direction. For investors who want Bitcoin without a corporate balance sheet, capital structure, or management discretion in the way, the wrappers are the cleanest read on spot price. They are also the baseline against which every other category in this universe should be measured.

MSTR Is a Leveraged Capital Allocation Story

$MSTR holds Bitcoin as its primary asset and uses convertible debt, ATM equity programs, and other capital markets tools to accumulate more. The software business generated $354 million in trailing revenue for the period ending September 30, 2025. The Bitcoin treasury dwarfs that operating business in economic significance.

The result is an equity that amplifies Bitcoin price through leverage. $MSTR's 90-day gain of 29.5% roughly doubled the ETF wrappers' 13 to 14%. The one-year decline of approximately 60% also far exceeded the ETF wrappers' one-year decline of roughly 27%. Leverage cuts both directions. $MSTR's BTC Exposure Score of 85 reflects the direct and leveraged nature of that exposure, and the dense filing cadence is driven by continuous capital markets activity rather than operating events.

The dominant variables for $MSTR are Bitcoin price, capital markets access, and BTC per share. Modeling $MSTR like an operating company misses the point. Modeling it like a pure Bitcoin ETF also misses the point, because the financing decisions introduce risks and return amplification the wrappers do not carry.

Miners Carry Operating Leverage on Top of Bitcoin Price

$MARA, $RIOT, and $CLSK are where the category fracture is most visible in the tape. $RIOT gained roughly 28% over the past 30 days and about 58% over 90 days. $CLSK gained about 12% over 30 days and 45% over 90 days. $MARA gained about 5% over 30 days and 62% over 90 days. All three crushed the ETF wrappers over the 90-day window.

The reason is operating leverage. Miners earn revenue by producing Bitcoin, and their economics depend on hashrate, energy cost, fleet efficiency, and Bitcoin price simultaneously. When Bitcoin price rises, miner margins expand faster than the price move itself because much of the cost base is fixed. The amplification works in reverse too. $MARA is down roughly 25% over one year while $RIOT has gained about 158% over the same period. Same Bitcoin price backdrop, completely different outcomes. Production economics, energy contracts, fleet composition, and balance sheet management create real differences within the miner group itself.

$RIOT's Filing Risk Score sits at 90, the highest in this universe, signaling an elevated disclosure cadence that demands explicit source review. $CLSK's filing activity is also elevated. For miners, the filing sections that matter are production updates, energy cost disclosures, and fleet expansion announcements, not the treasury line items that drive $MSTR's filings.

$MARA's trailing quarterly revenue was $174.6 million for the period ending March 31, 2026. $RIOT's was $167.2 million for the same period. $CLSK's latest loaded revenue was $766.3 million for the period ending September 30, 2025. These are real industrial businesses with real cost structures, and they require the same attention to revenue, margin, and capex that any industrial company demands.

COIN Answers a Different Question Entirely

Coinbase is the clearest case of a Bitcoin-linked equity that does not move with Bitcoin price in any simple way. $COIN's 30-day performance was negative roughly 8% while the ETF wrappers were roughly flat. The 90-day gain of 14.1% looks identical to the wrappers, but the mechanism behind it is completely different.

$COIN earns on transaction volume, custody, and services. When crypto trading activity is high, revenue rises. When it falls, revenue falls. The company reported $1.41 billion in revenue for the quarter ending March 31, 2026. That figure is the dominant variable, not Bitcoin spot. A Bitcoin price that grinds higher on low volume is worse for $COIN than a volatile Bitcoin price that drives heavy transaction activity.

$COIN's BTC Exposure Score of 70 reflects meaningful but not overwhelming direct sensitivity. The elevated filing risk reading is driven by regulatory complexity and the breadth of the business lines. The insider activity reading sits just below neutral, a pattern that does not stand out in either direction.

The Price Divergence Is the Argument

Over 30 days, $RIOT gained 28% while IBIT lost less than 1%. Over 90 days, $MARA gained 62% while $COIN gained 14%. None of this is random. It reflects miner operating leverage, $MSTR's capital structure amplification, the pure-beta design of the wrappers, and $COIN's volume-driven economics.

The Other Reading

The strongest objection to the category framework: over long enough horizons, all of these names collapse to Bitcoin price. If Bitcoin falls 50%, miners lose money on every block mined, $MSTR's leveraged treasury deteriorates, $COIN's trading volumes dry up, and the wrappers simply track the decline. From that vantage point, the category distinctions look like noise on top of a shared underlying exposure.

The one-year data gives the objection real teeth. $MSTR is down roughly 60% over one year. The ETF wrappers are down roughly 27%. Most of this universe sits in drawdown together. Correlation to Bitcoin price in sustained selloffs is high across every category here.

The objection still proves too much. The same logic would collapse equity analysis into a single macro factor for any sector with a shared input. Oil price explains a lot of variance across energy companies, but it does not make Exxon and a wildcat explorer the same investment. $RIOT gained roughly 158% over one year while $MARA lost roughly 25%, against an identical Bitcoin price backdrop. That divergence is entirely explained by operating and capital structure differences. The category framework is not a substitute for company-level work. It is the correct starting point for deciding which questions to ask of each filing.
