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.

IBIT pulling 292m monday through thursday while the whole eth complex goes negative for the week, allocators really did just pick a lane
Solana at 800k after 188m the week before? Those funds are too new to print steady numbers, the AUM base just isn’t there yet. Give them a year.
a year of paying management fees on products nobody trades. the SOL fund launch timing was terrible, right into the drawdown
too new is one thing but 800k for a whole week is a rounding error. the solana complex needs real market makers before these prints mean anything
a year is generous. the 188m week already proved demand exists for sol exposure, if the product cant capture it the allocators just move on to the next wrapper
The Wednesday 148.7 million BTC withdrawal getting absorbed without any price damage is the quiet tell here. Depth in those bitcoin funds is a different animal now.
absorbed is generous, the 148.7m was offset by IBIT alone. depth of one fund, not depth of the complex
292m of the week was ibit alone per the piece. one fund holding the whole complex up is strength right up until its first bad month
solana going from 188.1M to 800k in a single week is the real story here and everyone is staring at the BTC vs ETH fight instead
came here to say this. solana funds went 188.1m to 800k, thats basically a 99.5 percent cliff, and the headline is still framed as a btc vs eth fight lol
framing aside the eth outflows are the actual story here, 118m leaving in a week while btc prints green is a real rotation, not noise
strip IBIT out of the numbers and the entire complex is flat to red. one fund carrying the whole flows scorecard is fragile
IBIT doing 195.6 million in one session while the rest of the complex barely participates. One fund IS the market now.
and thats the hidden risk, when one fund IS the flow, one bad week at blackrock becomes a market event. concentration nobody prices in
exactly, IBIT at 195.6m in one session is more than double the weekly total of the entire eth complex. one quiet week at blackrock and the whole asset class flow story flips red
148.7m out on wednesday absorbed like it was nothing. five years ago that print would have been a red candle and a full twitter meltdown
ibit pulling 292m in four days while eth funds bled 118m is allocators voting with feet. solana scraping 800k at fund scale is basically a rounding error
solana at 800k weekly inflows is basically zero at fund scale. institutional demand there is one good quarter away from mattering or never mattering
118m out of eth funds in one week while ibit took 292m, the rotation story keeps getting harder to sell. whether 2681 holds decides if this is noise or a trend
everyone arguing btc vs eth and the zcash fund quietly bled 77.6m, worst print of the whole complex. flows coverage never covers the losers
zcash bleeding 77.6m is wild because that fund was the privacy trade for allocators who couldnt buy the coin. once it unwinds theres nowhere else to park that thesis
BTC absorbed a 148.7 million outflow on Wednesday and still ended the week green. That demand showing up on the dip is the part the scorecard framing missed.
eth bleeding 118m weekly while btc takes 82.9m is allocators simplifying books, not a verdict on the tech. solanas 800k is noise until its 8 figures
the friday 17.3m eth print was provisional, monday revisions keep flipping these weekly stories. wait for farside to settle before calling a rotation
even settled farside numbers get revised, but the direction holds either way. 118m out of eth funds while btc prints 82.9m green is rotation, not a data glitch
