Bitcoin vs. Ethereum vs. Solana ETFs: The Weekly Flow Scorecard Splits Sharply as BTC Gains 82.9 Million USD

Bitcoin vs. Ethereum vs. Solana ETFs: The Weekly Flow Scorecard Splits Sharply as BTC Gains 82.9 Million USD

The three flagship crypto ETF complexes told three very different stories during the September 28 to October 2 trading week. United States bitcoin ETFs recorded provisional net inflows of 82.9 million USD, ethereum ETFs posted 118 million USD in net outflows, and solana funds scraped together just 800,000 USD in inflows, according to Farside Investors data. The divergence lands at a delicate technical moment, with bitcoin hovering near 84,855 USD, ether around 2,681 USD and solana changing hands near 119.69 USD — and it suggests institutional allocators are no longer treating the major assets as one trade.

The Contenders

Bitcoin funds opened the week with 31 million USD in net inflows on Monday and added 66.2 million USD on Tuesday, absorbed a 148.7 million USD withdrawal on Wednesday, then rebounded with 102.7 million USD on Thursday and a reported 31.7 million USD on Friday. BlackRock’s IBIT did the heavy lifting with 292 million USD in net inflows across Monday through Thursday, including its largest single intake of 195.6 million USD on October 1. Ethereum’s picture inverted: after a modest 17.1 million USD inflow on Monday, ether funds bled every subsequent session — 2.8 million USD, then 59.6 million USD, then 55.4 million USD, and a provisional 17.3 million USD on Friday. Solana’s 800,000 USD weekly intake looks almost statistical noise next to its 188.1 million USD haul the week before, while niche products diverged further still: Hyperliquid ETFs added 3.4 million USD and the tracked Zcash fund lost 77.6 million USD.

Tech Stack Showdown

Flow behavior tracks each asset’s institutional wrapper maturity. Bitcoin’s ETF complex is the deepest and most liquid, with issuers like BlackRock, Fidelity, Bitwise and Grayscale providing tight spreads and established market-maker support, which is why large Wednesday withdrawals were absorbed without price dislocation. Ethereum’s fund lineup is nearly as broad — Fidelity’s FETH, Grayscale’s ETHE and its mini fund, VanEck’s ETHV and Franklin’s EZET all posted losses this week — but ether’s narrative is currently contested between staking yield, L2 value capture and corporate-treasury demand, leaving allocators less unified. Solana’s ETF suite is the newest and thinnest, so its weekly numbers swing violently between nine-figure inflows and near-zero prints depending on a handful of large orders. The plumbing itself, not just sentiment, explains much of the divergence.

Community & Ecosystem

Issuer-level detail sharpens the contrast. Fidelity’s FBTC posted 167.9 million USD in weekly net outflows despite a 29.3 million USD Friday intake, Bitwise’s BITB lost 38.6 million USD and Grayscale’s legacy GBTC shed another 54.6 million USD, while ARKB added 25.5 million USD, Grayscale’s lower-fee BTC fund gained 24.9 million USD and Morgan Stanley’s MSBT brought in 9.4 million USD. On the ethereum side, FETH’s 74.1 million USD in outflows led the retreat, ETHE lost 27.9 million USD and BlackRock’s ETHA was the lone bright spot with 6.5 million USD in inflows through Thursday. Notably, Friday’s totals remain provisional — Farside showed blank entries for IBIT, ETHA and ETHB when checked on October 3 — so the final scorecard could still shift modestly. The prior week’s context matters too: bitcoin’s intake collapsed from 2.39 billion USD across five consecutive positive sessions, and ethereum reversed from 689.8 million USD of inflows.

Adoption Metrics

Zoom out and the weekly split reads less like rejection and more like digestion. Bitcoin funds recorded inflows on four of five trading days even in a down-shift week, extending a pattern in which dips have been bought at the ETF wrapper level. Ethereum’s outflows arrive despite a steady drumbeat of institutional plumbing news around tokenization and staking integrations, suggesting holders are rebalancing rather than abandoning the asset. Solana’s whiplash weeks — 188.1 million USD followed by 0.8 million USD — indicate an investor base still dominated by a small number of large allocators, amplifying single-decision noise. For allocators using ETF flows as a positioning signal, the actionable read is that conviction currently concentrates in the bitcoin complex, with ether in a wait-and-see mode tied to its next catalyst and solana in an options-like profile.

The Final Verdict

One provisional week does not break a trend, but the shape of this one is instructive. Bitcoin’s 82.9 million USD intake looks anemic next to 2.39 billion USD the week before, yet four positive sessions out of five — anchored by IBIT’s 292 million USD — show demand persisting at a lower gear while price consolidates below the mid-80,000s. Ethereum’s 118 million USD exit is the week’s real divergence, reversing a nearly 700 million USD inflow streak and putting pressure on the bullish case that ether follows bitcoin’s institutional playbook with a lag. Solana’s near-flat print confirms its funds remain a high-beta satellite position. With sentiment readings in Greed territory and the market awaiting the next macro catalyst, the ETF flow scorecard has become the clearest real-time map of where institutional conviction actually lives — and right now it points squarely at bitcoin.
