Cathie Wood just dropped millions on SpaceX, Block, Coinbase, and Nvidia in a single buying blitz

Zara Reyes & Cole Bryant

ARK Invest spent roughly $54 million across two days in early August 2025, buying $20–23 million of SpaceX on August 6 and $21 million of Block on August 7 as both stocks fell. The purchases spanned SpaceX, Block, Circle, Coinbase, and Nvidia — funded by trimming Shopify, Palantir, and Roblox.

Over August 5–7, 2026, ARK Invest — the actively managed ETF firm led by founder, CEO, and CIO Cathie Wood — executed a multi-stock buying campaign spanning AI infrastructure, space technology, and crypto platforms.

About this episode

Cathie Wood doesn't manage money quietly — but this week felt different. Over just two days, ARK Invest deployed more than $54 million across SpaceX, Block, Circle, and Nvidia, buying into price drops, not after them. The episode digs into what the actual filings show (share counts and dates, nothing more), and why the narrative that forms around those filings tends to outrun what they say. The SpaceX position is the most loaded. The company beat Q2 revenue expectations at $7.8 billion, up 92% year-over-year, and the stock fell anyway — on cash burn tied to AI infrastructure spending. ARK made it the largest new commitment in ARKK at 4.73% of the fund. A trillion dollars in market cap has evaporated since the IPO debut. That number isn't shrinking. The Circle timing is almost surgical: OCC national trust approval, then New York limited-purpose trust approval, then ARK in the market four business days later with 109,000 shares. By August 6, they'd added another 143,000. Circle is now a top-ten ARKK holding. The thread running through all of it is ARK's mandatory daily disclosure requirement — the same mechanism that made Wood famous for transparency is now the thing that makes every future move a public event. No quiet exits. Just the morning filing, and retail doing the math.

Frequently asked

How much did Cathie Wood spend buying SpaceX stock in August 2025?

ARK Invest purchased 181,830 SpaceX shares across four ETFs — ARKK, ARKQ, ARKW, and ARKX — on August 6, 2025, at an estimated cost of $20–23 million. That single-day buy brought ARK's total SpaceX position to roughly $281 million, making it 4.73% of ARKK, the fund's largest new commitment.

Why did Cathie Wood buy Block stock when it was dropping?

ARK Invest bought approximately $21 million of Block shares on August 7, 2025, the same day Block fell roughly 6%. The purchase fits ARK's documented pattern of buying into price drops rather than waiting for stabilization, treating negative sentiment as a mispricing rather than a signal to avoid the stock.

Why did SpaceX stock fall after reporting 92% revenue growth?

SpaceX reported $7.8 billion in Q2 revenue, up 92% year-over-year, beating expectations — but the stock fell on cash burn from heavy AI infrastructure spending, with Nvidia among its suppliers. Investors appeared unconvinced that revenue growth would outpace capital expenditure, contributing to roughly $1 trillion in market cap lost since the IPO debut.

Why did ARK Invest buy Circle stock in July and August 2025?

ARK Invest bought 109,129 Circle shares on July 31 — four business days after Circle received New York limited-purpose trust approval on July 27 — then added 143,000 more shares on August 6. The two purchases totaled approximately $17.3 million and 273,343 shares, making Circle 3.90% of ARKK and a top-ten holding.

Does ARK Invest have to disclose its trades every day?

Yes. ARK Invest operates under a mandatory daily disclosure requirement, meaning every trade becomes public the following morning. This transparency turns routine portfolio moves into immediate media events, removes ARK's ability to reposition quietly, and means retail investors can track — and react to — every buy and sell in real time.

Zara Reyes: Hey — did you see the ARK disclosures drop?

Cole Bryant: I woke up to seventeen texts about it, so yes.

Zara Reyes: Block. Twenty-one million. On the day Block falls six percent. That's the one that got me.

Cole Bryant: Stop — she bought into the drop in real time?

Zara Reyes: August 7th, Block is down roughly six percent, ARK drops twenty-one million on it. And that's just one day of a two-day, fifty-four million dollar campaign.

Cole Bryant: Okay wait — what else is in the two days? Because I saw SpaceX in there and I need to understand that one. That's the stock that's already lost, like, a trillion in market cap since the IPO debut.

Zara Reyes: A hundred and eighty-one thousand eight hundred and thirty shares across four ETFs — ARKK, ARKQ, ARKW, ARKX — on August 6. Twenty to twenty-three million dollars. One day.

Cole Bryant: Bro. And she trimmed — wait, who did she trim to pay for this?

Zara Reyes: Shopify. Palantir. Roblox. Gone — well, trimmed — to fund it. And all of this, by the way, while the Federal Reserve is holding rates but three officials just voted for a hike, September tightening odds are above sixty, and there's a seventy-million-dollar Coldcard wallet hack cratering crypto sentiment. She bought into all of that.

Cole Bryant: The Coldcard hack is wild as a cherry on top. Like the backdrop could not have been more red.

Zara Reyes: But that's the word I want to slow down on — 'campaign.' Everyone's calling this a coordinated campaign and I'm like, wait, what are the filings actually showing? Dates and share counts. That's it. That's what a mandatory daily disclosure gives you.

Cole Bryant: Okay but — three sectors, same two days? SpaceX on August 6, Block on August 7, Nvidia in there too — that's not a coincidence, bro.

Zara Reyes: No but that's exactly my point. ARK's daily disclosure mandate means every single trade goes public immediately — so what looks like a coordinated war room is actually just... Tuesday's filing becoming a media event by Wednesday morning.

Cole Bryant: The transparency IS the story.

Zara Reyes: The transparency IS the story. And here's what's actually new: SpaceX reports $7.8 billion in Q2 revenue, up 92% year-over-year, beats expectations — stock falls anyway on cash burn. Cathie buys INTO the fall. Not after it stabilizes. Into it. That's the pattern. It's like your friend who always buys concert tickets the day a bad review drops — they're not ignoring the review, they just think everyone else is overreacting to it.

Cole Bryant: Okay that is — wait, that actually makes the Circle thing click too, right? Because Circle gets OCC national trust approval, stock is volatile with the rest of crypto, ARK buys 143,000 shares on August 6. Same move.

Zara Reyes: Same exact move. Bad review drops — she buys the tickets. And because the disclosure is mandatory and immediate, by the time retail sees it, the narrative's already written. 'Cathie sees what the market missed.' But lowkey — the filing didn't say that. The filing said she bought shares on a specific date at a specific price.

Cole Bryant: So the trade and the story about the trade are — dude, they're inseparable at this point.

Zara Reyes: But that's exactly where the wrong take lives, actually. Because the take circulating right now is — '92% revenue growth, Cathie's obviously right, the dip is a buying opportunity.' And I'm like, wait. Wait. That's not what happened.

Cole Bryant: No, say it. Because I've seen that take everywhere today.

Zara Reyes: The stock didn't fall on a revenue miss. SpaceX beat. It fell on cash burn. AI infrastructure spending, Nvidia as a supplier — that's where the money's going. So '92% growth covers it' is just... it's not the argument. The argument is whether the burn ever stops.

Cole Bryant: Dude, okay — but doesn't growth at that scale eventually just outrun the burn? Like isn't that the whole — wait, no, actually I know what you're gonna say.

Zara Reyes: A trillion dollars in market cap gone since the IPO debut. That is not short-term sentiment.

Cole Bryant: Bro. It's like — okay, I had this image the second I saw the number. Your neighbor's house loses half its appraised value because the inspector found foundation cracks. And you turn around and buy the house next door at full price because you like the neighborhood demographics. Like, growth is the demographics. The cracks are still there.

Zara Reyes: And Elon's framing the cracks as strategic capex. 'AI-powered, Mars-colonizing vision' — that's the pitch. A trillion dollars of destruction is not a rounding error on that pitch.

Cole Bryant: No, I don't buy that it's obviously wrong — but I don't buy that it's obviously right either. And ARK just made SpaceX its largest new commitment. 181,830 shares, 4.73% of ARKK, roughly $281 million total. Across four ETFs. If this thesis breaks—

Zara Reyes: Four ETFs feel it. And the Circle and Coinbase piece — whether the daily disclosure model actually becomes a liability over the next 60 to 90 days — that's the part of this I want to get to, because it changes everything about how retail reads these filings.

Cole Bryant: Okay but the Circle timing is — dude, it's almost too clean to be accidental. OCC national trust approval, July 10. New York limited-purpose trust approval, July 27. ARK buys 109,129 shares on July 31. Like, that is four business days after the New York stamp.

Zara Reyes: Four days. And then August 6 she adds another 143,000 shares. That's 273,343 total across the campaign — seventeen-point-three million dollars. Circle is now 3.90% of ARKK. Top ten holding.

Cole Bryant: Stop — top ten?

Zara Reyes: Sitting right next to Coinbase — 1.6 million shares, two-forty-three million dollars — and Block. Three crypto infrastructure positions, all tightening at the same moment. And the CLARITY Act just hit Senate recess without a floor vote. So the regulatory framework is still wide open.

Cole Bryant: Wait — so she's stacking Circle, Coinbase, and Block while the actual law governing all of them hasn't passed? That's either genius hedging or — no, actually, wait — is it just that she doesn't know which framework wins either, and she's buying all three rails so it doesn't matter?

Zara Reyes: That's the coherence question. Is stablecoin infrastructure plus crypto exchange plus crypto-fintech one unified thesis — or is it three separate bets with one retrofit narrative stapled on top?

Cole Bryant: Bro. And TSMC is also in the same buy window — like, she dropped twenty-eight-point-seven million combined on SpaceX and TSMC, trimmed Amazon and Alphabet to do it. The thesis keeps expanding.

Zara Reyes: Which brings me to the part that actually keeps me up — the daily disclosure thing. Because the next 60 to 90 days, every single ARK move is a public performance. If Circle's valuation wobbles, if SpaceX selling pressure gets real — Wood doesn't get to quietly reposition. She has to add, hold, or exit on a fully public stage. And retail's watching with five years of underperformance already in their feed.

Cole Bryant: So the transparency that made the Cathie effect real — that's the same thing that makes the next move impossible to hide.

Zara Reyes: The one I'm not over? Four business days. OCC approves Circle, New York approves Circle, and Wood is in the market 96 hours later with a hundred-and-nine-thousand shares. That's not a thesis. That's a timer.

Cole Bryant: Mine is SpaceX at 4.73% of ARKK. Like — she made it the biggest new bet in the flagship fund while a trillion dollars of market cap is still just... gone. That number doesn't shrink. It's just sitting there.

Zara Reyes: And the next 90 days, every single one of those positions — SpaceX, Circle, Coinbase, Block — plays out on a mandatory public stage. No quiet exits. Just the filing, every morning, and retail doing the math.

Cole Bryant: Dude. Cathie Wood said 'radical transparency' and now radical transparency is — wait, it's the whole game. For better or genuinely terrible. I kind of love this storyline, bro.

Zara Reyes: Okay, I'm toasting the disclosure mandate. The most unintentionally chaotic brand lever in finance. Cheers to that.
