TL;DR
Bitcoin closed near $62.8K on Sunday, down roughly 3% w/w, its worst week in six.
Spot Bitcoin ETFs bled $389.7M between Aug 10 and 14, the largest weekly outflow in six weeks.
July CPI printed 0.1% MoM and 3.4% YoY, in line with consensus.
SEC abruptly canceled its Aug 14 Regulation Crypto vote, delaying the first formal proposal.
Strategy sold another 1,690 BTC for $108.6M and raised $653M in fresh equity.
Week ahead: Trump crypto summit (Aug 19), FOMC minutes (Aug 20), Jackson Hole (Aug 27-29).
1. Weekly Opening Insight
The week revealed a disconnect that will shape September. Softer July CPI and PPI landed on Wednesday and Thursday, and by the old playbook, Bitcoin should have rallied. Instead, spot Bitcoin ETFs posted their heaviest weekly withdrawal in six weeks at $389.7M, BTC lost about 3%, and the CLARITY Act, Regulation Crypto, and the tokenization exemption all stalled in the same 72-hour window. Institutional allocators are trimming risk ahead of Jackson Hole, not chasing rate-cut trades on the print.
Here's what crypto investors should understand about the week ahead…
In Partnership With Roku
Blu Dot surpasses 2,000% ROAS with self-serve CTV ads
Home furniture brand Blu Dot blew up on CTV with help from Roku Ads Manager. Here’s how:
After a test campaign reached 211,000 households and achieved 1,010% ROAS, the brand went all in to promote its annual sales event. It removed age and income constraints to expand reach and shifted budget to custom audiences and retargeting, where intent was strongest.
The results speak for themselves. As Blu Dot increased their investment by 10x, ROAS jumped to 2,308% and more page-view conversions surpassed 50,000.
“For CTV campaigns, Roku has been a top performer,” said Claire Folkestad, Paid Media Strategist, Blu Dot. “Comping to our other platforms, we have seen really strong ROAS… and highly efficient CPMs, lower than any other CTV partner we've worked with.”
Using Roku Ads Manager, the campaign moved from a pilot to a permanent performance engine for the brand.
2. POLL

Best Performing Large-Cap: Ethereum (down 1.8%)
ETH held up best in the majors this week, closing near $1,874 on Sunday. Cooling inflation data and thinner selling in ETH ETFs kept the pullback shallow relative to the rest of the top four.
Worst Performing Large-Cap: XRP (down 3.5%)
XRP slipped to $0.99, losing the $1.00 handle as CLARITY Act cloture odds slid to 19% and XRP ETF weekly inflows registered a modest $2.25M.
What Drove Markets This Week
Softer CPI and PPI failed to spark a rally as ETF outflows resumed and the SEC delayed its Regulation Crypto vote, extending the institutional risk-off tone.

4. The Big Story of the Week
Spot BTC ETFs Bleed Almost $390M Despite Soft Inflation Print
What happened
US spot Bitcoin ETFs recorded $389.7M in net outflows between August 10 and August 14, the largest weekly withdrawal in six weeks per SoSoValue. Ethereum ETFs also ended the period slightly negative at $2.26M in outflows. Solana ETFs bucked the trend with $10.26M in inflows (August 10 marked the largest single-day since May).
Why it matters
The outflow arrived alongside benign inflation data. The CME FedWatch cut September hike odds to 42% after the CPI print, and Treasury yields fell across the curve. Yet allocators still pulled capital. Total net assets across US spot Bitcoin ETFs stood near $76.6B as of August 14.
Investor takeaway
Watch whether outflows persist through the Aug 27-29 Jackson Hole symposium. If Chair Warsh signals openness to easing, flows should reverse quickly. A second week of $200M-plus BTC outflows would confirm a broader de-risking cycle.

5. Key Market Developments
5.1 July CPI Cools to 3.4%, Core PPI at 4.2%
What happened
The BLS reported July CPI rose 0.1% MoM and 3.4% YoY, both in line with consensus. Core CPI eased to 2.5% YoY. Producer prices came in flat, with core PPI at 4.2% YoY, matching estimates.
Bull case
Two consecutive soft prints strengthen the case for a September pause, easing bond yields and supporting risk assets over time.
Bear case
Both readings were "in line" rather than "under." The three FOMC dissenters from July 29 have not softened their public stance, and headline inflation remains stubbornly above the 2% target.

5.2 SEC Cancels Regulation Crypto Vote
What happened
The SEC canceled its Aug 14 open meeting to propose Regulation Crypto, its first formal crypto-specific rulemaking. The separate tokenization innovation exemption was also delayed indefinitely.
Bull case
The proposal is only deferred, not withdrawn. The CFTC Innovation Advisory Committee convenes Aug 20 and may fill the vacuum on commodities-based crypto oversight.
Bear case
With CLARITY Act cloture set for Sept 15 and unlikely to hit 60 votes, both the legislative and regulatory tracks have stalled within the same fortnight.

5.3 Trump to Host Crypto CEOs at White House Aug 19
What happened
President Trump is expected to attend a Wednesday gathering with executives from Coinbase, Ripple, Gemini, Kalshi, Chainlink Labs, and a16z. SEC Chair Atkins, CFTC Chair Selig, Treasury Secretary Bessent, and Commerce Secretary Lutnick are expected to participate.
Bull case
The event functions as a prelude to the CFTC Innovation Advisory Committee's first meeting Aug 20, signaling executive-branch intent to keep moving on crypto policy.
Bear case
Optics without a vote. Polymarket odds for CLARITY passage in 2026 sit at 19% despite the summit.

6. On-Chain Data Insight
The Data
Top-20 crypto market cap totals $2.087T, with Bitcoin representing 60.84%, Ethereum 10.88%, and USDT+USDC together near 12.2%, per CoinStats aggregated data from August 15.
What the Data Shows
Nearly three-quarters of top-20 value now sits in Bitcoin plus dollar-pegged stablecoins.
What it might signal
Capital is defensive, not distributing. Altcoin rallies remain narrow and idiosyncratic (Chainlink, Curve, Worldcoin) rather than broad. Until stablecoin share compresses, altseason is mechanically unlikely.

7. Narrative Watch
The Jackson Hole Setup
Why it is gaining attention
Fed Chair Kevin Warsh delivers his first Jackson Hole address on Aug 27-29 after July 29's 9-3 hold. Traders are looking for a clean signal on the September FOMC meeting.
Why it could grow
Two soft inflation prints and a negative 23K July payroll give Warsh cover for a dovish tilt. Crypto has historically front-run Fed pivots by two to six weeks.
Why it could fade
Warsh has reduced Fed forward guidance since taking the chair, and the three hawkish dissenters remain vocal. A measured stance could trigger a sell-the-news reaction.

8. Investment Theme of the Week
Solana ETFs Quietly Diverge
Thesis
US spot Solana ETFs pulled in $10.26M last week, while Bitcoin and Ethereum funds bled. Cumulative SOL ETF net inflows stood at $1.16 billion as of August 14.
Catalysts
Solana's Aug 17 mainnet upgrade cuts slot times toward 350 milliseconds as the first step. Additional Solana ETF filings are expected, and tokenized-equity share on Solana continues to build fundamental usage.

Risks
Solana Company reported a Q2 loss of $30.3M on SOL write-downs. If BTC breaks $60K, correlation is likely to drag SOL with it despite the inflow story.

9. Smart Crypto Insight
Reading Divergence in ETF Flows
When Bitcoin ETFs bleed while Solana, XRP, and HYPE ETFs collect, the signal is rotation, not exit. Three of the six crypto ETF categories tracked by SoSoValue took inflows for the week ended August 14, even as the U.S. dollar hovered near recent lows.
The pattern for serious investors: when BTC dominates outflows during a mixed print, allocators are usually rebalancing toward smaller pockets of asymmetry, not liquidating crypto exposure. Track SoSoValue's weekly category snapshot rather than the headline BTC number alone.
10. Quick Hits from the Week
Cboe BZX filed to list 3x leveraged Bitcoin and Ether ETFs, adding leverage into a crowded long book.
Strategy sold another 1,690 BTC for $108.6M, its fourth 2026 disposal.
Coldcard exploit total climbed to 1,816 BTC (about $116M) drained from over 5,200 addresses.
Circle's Arc mainnet remains on track for a Sept 16 launch with 11 founding validators.
Riot Bitcoin mining platform signed a 20-year $9.1B lease at its Rockdale campus with a leading frontier AI lab.
11. Closing Macro Thought
Mid-August delivered a rare setup: soft inflation, softer labor, and softer regulation, yet risk assets did not rally. That signals allocators are waiting for Jackson Hole, not fading it. If Chair Warsh acknowledges the labor deterioration, September repricing arrives before the FOMC meets.
The next fortnight tests whether Warsh channels a pivot or holds the line, and whether the CLARITY Act clears its September window before the midterm cycle closes it.
