Cathie Wood’s ARK ETFs Roar Back With Record-Breaking Inflows
After years of outflows and underperformance, ARK’s flagship funds are seeing their biggest surge of investor cash since the 2021 boom.
Cathie Wood’s ARK ETFs are catching fire again, with investors piling back into the volatile, high-conviction funds after months of strong performance. Over the past week, the firm’s 13 U.S.-listed ETFs have attracted $3.7 billion in inflows, a huge sum for a lineup with $21.5 billion in total assets.
The surge was led by record-breaking single-day hauls. On Monday, the flagship ARK Innovation ETF (ARKK) took in $1.1 billion, followed by $1.4 billion on Tuesday—larger than any single-day inflows it saw even at the height of its popularity in 2021. 
The ARK Next Generation Internet ETF (ARKW) posted a $349 million inflow on Tuesday, its biggest ever.
Prior to this run, ARK’s ETFs were sitting on steep year-to-date outflows. Now, they’re $2.6 billion in the green for 2025.
ARKK alone accounted for $2.8 billion of last week’s inflows and now holds $8.6 billion, or 40% of ARK’s total assets. ARKW took in $707 million, pushing its assets to $2.8 billion.
Most of ARK’s other ETFs, including its second-largest, the $5.4 billion ARK 21Shares Bitcoin ETF (ARKB), have seen little flows activity compared to ARKK and ARKW.
From Peak to Plunge to Rally
It’s the most dramatic change in momentum for ARK since its peak. During the retail trading boom of 2020 and 2021, ARK ETFs were among the most popular products in the market. ARKK topped $28 billion in assets, while ARKW peaked near $10 billion.
But the 2022 bust was brutal for the funds. Both fell about 80% from peak to trough, and assets shrank dramatically. At one point, Wood famously sold Nvidia just before its historic AI-driven surge—a move that became a symbol of the firm’s post-bubble struggles.
That narrative has shifted this year. From an April low of around $40, ARKK has nearly doubled in three months, helped by well-timed bets on Coinbase, Roblox, Shopify, Palantir, Robinhood, and the Circle Internet Group IPO. 
ARKW has also doubled off its lows and is now just 13% below its 2021 peak, compared with a 50% gap for ARKK (thanks in part to avoiding lagging health care names that have weighed on its more diversified sibling).
Echoes of 2020–2021
The timing of ARK’s rebound coincides with another wave of retail enthusiasm for meme stocks, “cult” stocks, and other high-volatility trades. The setup has shades of the pandemic-era boom that first propelled ARK to prominence.
After several years of underperformance and ill-timed calls over the past few years, the firm’s active strategies now appear better aligned with the trends driving today’s market.
Still, despite the rally, ARK remains far from its 2021 heights. Total ETF assets are still only a third of their peak above $60 billion, and some funds—like the ARK Genomic Revolution ETF (ARKG)—are still down nearly 80% from their highs (assets in that fund are $1 billion, down from a peak of $13 billion!)
Even so, this is the largest wave of inflows ARK has seen since its heyday. Whether it’s a sustainable comeback or a brief hot streak is unclear, but for now, Cathie Wood is back at the center of the action.
