Bitcoin leads ETF flows, but Ethereum builds institutional base for Q2 showdown

Institutional flows across the top two crypto assets have been pretty split this cycle. According to SoSoValue data, Bitcoin [BTC] ETFs have pulled in $2.44 billion in net inflows this April, adding to March’s $1.32 billion. On the contrary, Ethereum [ETH] ETFs are lagging, bringing in about $540 million in net inflows. To put that in perspective, BTC ETFs have attracted nearly 4.8x more capital than ETH ETFs. On the charts, the impact is pretty clear. Bitcoin has been up about 13.5% in April, which is roughly 1.5x Ethereum’s performance over the same period. Because of that, the ETH/BTC ratio has already slipped about 3.15% so far in Q2, extending the weakness from the previous two quarters. In this context, calling Ethereum’s current cycle fully “institutional-led” feels a bit premature. That said, not everyone in the Ethereum camp agrees with that take. The key counterargument is coming from Tom Lee’s BitMine [BMNR]. Ethereum executives argue BMNR could actually outperform Bitcoin’s Strategy [MSTR] over time. The logic is pretty straightforward - BMNR accumulates ETH, stakes a portion of it, and then uses the staking yield to keep compounding its position. With 72% of BMNR’s ETH holdings currently staked, the model does have some real traction behind it. Still, the bigger question is whether BMNR-style accumulation is enough to offset the growing institutional flows into Bitcoin and actually help ETH close the gap on BTC’s performance. Notably, based on the flow data, it might still be a bit too early to completely dismiss Ethereum’s “institutional” narrative. Tom Lee’s case for Ethereum as the next "Wall Street” trade Unlike short-term holders, institutional players usually build positions with a longer-term mindset. Notably, Tom Lee’s entire case for ETH leans on this idea. Even with weaker ETF inflows, Ethereum still leads on several key on-chain metrics, ranging from about 65% dominance in the real-world assets (RWA) sector to over 50% of stablecoin market share, which translates to nearly $167 billion in on-chain liquidity. Now, when you look at the incremental growth across these sectors, Tom Lee’s case starts to hold more weight. According to DeFiLlama, the RWA market has expanded roughly 5x in just over a year, moving from around $4.1 billion to $25.6 billion. In this context, Ethereum’s 65% dominance means it is still capturing a large share of the fastest-growing sector, especially as more institutional-grade products like JPMorgan’s tokenized money market fund (MONY) start moving on-chain. Naturally, attention is now shifting to the stablecoin market.  Historically, stablecoins mostly served as a defensive tool. However, that role has clearly evolved. Stablecoins are increasingly becoming the core settlement layer of the crypto economy, reflected in roughly 25% market growth since 2025. In that context, recent remarks from Coinbase executive Jesse Pollak carry added significance, particularly for Ethereum.  From a longer-term perspective, with Ethereum holding around 50% of the stablecoin market share, it increasingly looks positioned to serve as the core infrastructure layer for AI-driven interfaces facilitating crypto payments. In short, ETH’s dominance across both liquidity and RWAs suggests a deeper Wall Street-style phase could still be forming this Q2 cycle, despite relatively weaker ETF flows. Final Summary Bitcoin leads institutional inflows, resulting in ETH/BTC weakness so far in the 2026 cycle. Ethereum has dominated RWAs and stablecoins, creating a key divergence that could support its institutional positioning against Bitcoin.
