Which ARK Fund? Comparing ARKK, ARKW, and the ARK Venture Fund

If you've looked at multiple ARK funds and wondered how different they actually are, the monthly N-PORT filings — holdings disclosures required of registered investment companies — give a clear answer. As of January 2026: ARK Innovation ETF (ARKK) manages $6.7 billion across 47 positions; ARK Next Generation Internet ETF (ARKW) holds $1.8 billion across 49. Twenty-eight securities appear in both — and three of those are new to the overlap since October 2025.

First, understand what you're always getting: the shared core

Those 28 shared names represent about 60% of ARKK's holdings by count and 57% of ARKW's. By portfolio weight, roughly 60% of ARKK and about 65% of ARKW sit in securities both funds hold simultaneously. If you hold one of these funds, you already have meaningful exposure to the other's core bet. The heaviest shared names — Tesla (TSLA), Coinbase (COIN), Roku (ROKU), Shopify (SHOP), Robinhood (HOOD), and Palantir (PLTR) — appear near the top of both funds with broadly similar allocations.

One interesting divergence: AMD (AMD) ranks 8th in ARKK at 4.0%, but holds 2nd place in ARKW at 7.0%. The overlap composition also shifted since October 2025: CoreWeave (CRWV) and Alphabet (GOOG) crossed from ARKW-only into both funds, and Broadcom (AVGO) appeared in both simultaneously. On the other side, Gitlab and Pinterest moved from shared to ARKW-only after ARKK dropped them.

Choose ARKK if life sciences and broad disruption matter to you

The holdings exclusive to ARK Innovation are where the funds genuinely diverge. Its two largest ARKK-only positions are both in healthcare: CRISPR Therapeutics (CRSP) at 5.5% and Tempus AI (TEM) at 4.9%. Below those, a cluster of genomics, gene-editing, and diagnostics names adds roughly 20% to ARKK's total weight — a theme with no equivalent in ARKW. Several of these positions moved up sharply from the prior period:

• Beam Therapeutics (BEAM) — 3.5%
• Teradyne (TER) — 3.6%
• Twist Bioscience (TWST) — 2.6%
• 10X Genomics (TXG) — 2.2%
• Archer Aviation (ACHR) — 2.1%
• Illumina (ILMN) — 1.5%
• Intellia Therapeutics (NTLA) — 1.8%
• Natera (NTRA) — 1.4%
• Veracyte (VCYT) — 1.3%
• Recursion Pharmaceuticals (RXRX) — 1.3%

ARKK also holds defense, automation, and aerospace names that don't appear in ARKW: BWX Technologies (BWXT) at 1.2%, Kratos Defense & Security (KTOS) at 1.3%, and Deere & Co (DE) at 1.5%. If the thesis you're expressing is "disruption broadly" — across biotech, robotics, energy, and defense, not just software — ARKK is the more complete vehicle of the two.

Choose ARKW if you want an internet-native and crypto emphasis

ARK Next's exclusive holdings tilt toward internet platforms, cloud software, and digital assets. The largest ARKW-only position is the ARK 21Shares Bitcoin ETF (ARKB) at 6.4% — an ARK-managed bitcoin product sitting inside the ARK Next portfolio itself. ARKW also holds the 3iQ Ether Staking ETF and 3iQ Solana Staking ETF, creating exposure across bitcoin, ether, and solana in a fund that doesn't otherwise hold any crypto directly. Alphabet (GOOG) moved into the shared category this period, but its ARKW weight jumped to 3.5% — now the fund's 8th-largest position. Other ARKW-only names include:

• CrowdStrike (CRWD) — 1.9%
• Cloudflare (NET) — 1.6%
• Datadog (DDOG) — 1.2%
• DoorDash (DASH) — 1.2%
• Rubrik (RBRK) — 1.2%
• MercadoLibre (MELI) — 1.2%
• Pure Storage (PSTG) — 1.2%
• Netflix (NFLX) — 1.1%
• Gitlab (GTLB) — 1.1%
• Genius Sports (GENI) — 1.1%
• Spotify (SPOT) — 1.0%
• Figma (FIG) — 0.7%
• Pinterest (PINS) — 0.9%
• Unity Software (U) — 0.9%
• Toast (TOST) — 1.0%
• Qualcomm (QCOM) — 1.0%
• Salesforce (CRM) — 0.5%
• Nextdoor (NXDR) — 0.8%

No biotech, no defense, no industrial names — ARKW's unique exposure is exclusively digital. If your interest is in the internet economy specifically, including the crypto infrastructure layer alongside public software names, ARKW is the more focused expression of that thesis.

What holding both actually means

If both funds interest you, it's worth seeing the overlap clearly before combining them. The 28 shared names as of January 2026 — Tesla, AMD, Coinbase, Roku, Shopify, Robinhood, Palantir, Roblox (RBLX), Circle Internet (CRCL), BitMine (BMNR), Amazon (AMZN), NVIDIA (NVDA), CoreWeave (CRWV), TSMC (TSM), Bullish (BLSH), Block (XYZ), Baidu (BIDU), Meta (META), Airbnb (ABNB), DraftKings (DKNG), PagerDuty (PD), Alibaba (BABA), Trade Desk (TTD), Broadcom (AVGO), Alphabet, and a few smaller names — represent most of ARKW's portfolio weight. Combining the two funds adds ARKK's exclusive names on top, but the majority of ARKW is already embedded in ARKK's positions. Three names newly joined the overlap this period (CoreWeave, Alphabet, Broadcom), and two left it (Gitlab, Pinterest) — a reminder that the overlap isn't static.

A different option entirely: the ARK Venture Fund for pre-IPO access

Three-fund overlap by security count, January 2026. ARK Venture Fund's 57 unique holdings dwarf the ETFs' exclusive positions — nearly all of those are private companies.

If neither ARKK nor ARKW has what you're looking for, it may be because the companies you're interested in — SpaceX, OpenAI, xAI, Anthropic — aren't public yet. The ARK Venture Fund holds all of them, alongside dozens of other private companies. Its January 2026 N-PORT filing shows $554 million in assets across 105 holdings — up from $380 million just three months earlier, and roughly 8× from a year ago. Eighty-five of those holdings, representing about 80% of the portfolio, are Level 3 securities: private company stakes valued using unobservable inputs, meaning the fund itself sets the prices rather than markets.

The largest private positions by reported weight — and a few notable changes from October 2025:

• SpaceX — ~10.9% (two share classes; now the largest single private position, up from ~7.7%)
• xAI — ~6.1% across three tranches (up from ~3.7% — the quarter's biggest mover)
• Figure AI — 4.1%
• Anthropic — 2.5%
• Neuralink — 2.7%
• OpenAI Group PBC — ~2.9% across three tranches (down from ~4.3%; the fund's disclosures now reflect OpenAI's public benefit corporation restructuring)
• Groq — ~2.9% (AI inference chips)
• Databricks — ~3.5% across three tranches
• Epic Games — 2.7% (up from 1.2%)
• Zipline — ~3.3% across three tranches (autonomous drone delivery; up from ~0.8%)
• Boom Technology — ~3.2% (supersonic aviation; up sharply from ~0.6%)
• Kalshi — 1.8% (prediction markets platform; new position)
• X-Energy Reactor Company — 1.4% (small modular nuclear; new position)

The fund also holds a mix of publicly traded names at smaller weights — CRISPR Therapeutics, Beam Therapeutics, Robinhood, Tesla, Coinbase, Archer Aviation — many of which overlap with ARKK and ARKW. The critical practical difference: ARK Venture Fund is an interval fund, not an ETF. It does not trade on an exchange. Redemptions are limited to defined windows — typically quarterly — and may be capped. The Level 3 valuations also mean reported weights reflect ARK's own pricing, not market consensus. Both factors are worth understanding clearly before comparing it to the daily-liquidity ETFs.

This data is drawn from N-PORT filings submitted to the SEC for the period ending January 31, 2026. Holdings, weights, and fund sizes reflect those filings and change with each monthly disclosure.
