Week in Numbers

Spot crypto ETFs logged $1.07 billion in net inflows across the August 3-7 trading week, according to InflowScan data — a sharp reversal from the prior week's $80.6 million in redemptions. The five-session run marked the strongest weekly total in over a month and reset the momentum picture heading into mid-August.

Bitcoin products absorbed $840.4 million, or roughly 78% of the week's net buying. Ethereum products drew $232.4 million. XRP and Solana funds were rounding errors by comparison, with combined net activity below $1.5 million. The concentration into the two majors is consistent with institutional rebalancing rather than broad crypto-basket buying.

Daily Flow Breakdown

Flows built through midweek and tapered into Friday, with every session positive — an uninterrupted five-day green streak that had not been recorded since June.

  • Monday Aug 3: +$124.2M ↑
  • Tuesday Aug 4: +$255.0M ↑
  • Wednesday Aug 5: +$305.3M ↑
  • Thursday Aug 6: +$237.2M ↑
  • Friday Aug 7: +$150.8M ↑

Wednesday's $305.3 million print was the standout — the largest single-session inflow of the week and the anchor of the run. The Thursday follow-through kept the tape one-way, while Friday's softer number points to some profit-taking into the weekend rather than a shift in the underlying bid.

ETF Leaderboard

BlackRock dominated the week's league table on both the BTC and ETH sides, according to InflowScan data. IBIT alone captured 64% of the entire week's net inflow.

  • IBIT (BlackRock): +$689.5M ↑
  • ETHA (BlackRock): +$202.1M ↑
  • FBTC (Fidelity): +$115.4M ↑
  • ARKB (ARK Invest): +$50.4M ↑
  • MSBT (Morgan Stanley): +$21.4M ↑

The outflow side was quiet. Grayscale's ETHE bled another -$4.7M ↓, extending its long-running redemption pattern. Volatility Shares' XRPT and XRPI, together with ProShares' SOLZ and UXRP, collectively shed roughly $2.5 million — small in absolute terms, but the direction is consistent with the underlying XRP price weakness.

The IBIT/ETHA concentration is the story within the story. BlackRock's two flagship products absorbed $891.7 million — 83% of net industry flow. That level of single-issuer share points to institutional allocators routing through the largest, most liquid vehicles rather than distributing across the issuer set.

Price Scorecard

Price action confirmed the flow bid, with the two majors closing higher and Solana finishing flat. XRP was the clear laggard.

  • BTC: $63,499 → $64,892 +2.2% ↑ (range $64,099-$65,423)
  • ETH: $1,883 → $1,915 +1.7% ↑ (range $1,891-$1,942)
  • SOL: $73.55 → $73.63 +0.1% ↑ (range $72.38-$74.33)
  • XRP: $1.086 → $1.020 -6.0% ↓ (range $1.012-$1.042)

Bitcoin's weekly range was tight — roughly 2.1% peak-to-trough — despite the size of the flow bid. That compression suggests the ETF buying is being absorbed by supply near the $65K handle rather than driving a directional breakout. Ethereum traded a similarly narrow band, capped below $1,942 for most of the week.

XRP's 6.0% decline against a modest ETF outflow of roughly $1.7 million across the four listed XRP products points to spot-market selling rather than fund-level rotation. The divergence between XRP and the majors is the cleanest signal in the week's tape.

Stablecoin Pulse

Stablecoin supply expanded only marginally. USDT added $110 million to close the week at $183.2 billion, and USDC grew $7 million to $72.0 billion, according to InflowScan data. The combined $117 million weekly print is small relative to the $1.07 billion in ETF inflows, which is consistent with capital rotating out of stablecoin float and into fund products rather than fresh dollars entering the system.

FlowScore Check

End-of-week FlowScores from InflowScan put ETH marginally ahead of BTC on flow momentum:

  • ETH: 60.56 / 100
  • BTC: 57.24 / 100
  • SOL: 53.38 / 100

All three sit in the moderate-positive zone. ETH's edge is modest but comes on materially smaller absolute flow ($232M vs $840M for BTC), which points to relatively stronger flow-per-AUM intensity on the Ethereum side. SOL's mid-50s reading despite negligible fund activity reflects the price stability rather than an active flow bid.

Week's Top Stories

  • BlackRock extends dominance: IBIT and ETHA led daily flow tables on four of five sessions, consistent with the weekly leaderboard picture.
  • EIP-8361 rejected: Ethereum validators signaled 99.7% opposition to a proposal targeting network inflation via reduced staking rewards, with Aave founder Stani Kulechov and Sharplink among prominent opponents.
  • Bitcoin security sprint: An AI-assisted audit surfaced 6,700 potential issues in Bitcoin infrastructure over 55 hours, though triage of genuine vulnerabilities remains open.
  • Treasury sanctions crypto exchanges: The US-Iran standoff extended into digital-asset infrastructure with fresh OFAC designations, adding a compliance overhang for exchanges with international counterparty exposure.
  • Coldcard hack and Clarity Act delay: A hardware-wallet incident and legislative slippage on the Clarity Act framework capped an otherwise constructive tape for institutional narrative.

The Read

The week's dominant signal is BlackRock's grip on flow share. When one issuer captures 83% of net industry buying across two products, the marginal ETF bid is functionally the marginal IBIT/ETHA bid. That concentration cuts both ways — it amplifies the impact when BlackRock's allocator base is active, and it removes the diversification cushion when that base steps back.

Bitcoin's tight range against $840 million of net inflow is the second signal worth tracking into the coming week. Price containment near $65,000 in the face of that flow points to persistent supply at the handle. A break above, if it comes, would historically be associated with a shift in the dealer-hedging posture rather than a marginal-bid story.
