If you want to invest more than $1M, here's how the Altcopy Index behaves today

Almost every "best Hyperliquid vault" guide — including parts of my own — quietly assumes you're investing a few thousand dollars. At that size, the only question that matters is which vault is good.

If you're putting in real money — a million dollars or more — the question flips. It stops being "which vault is best" and becomes "which vault can even hold my money without breaking?" Those are very different questions, and the second one is the one nobody on Hyperliquid's official page will answer for you. The Altcopy Index answers it by design. You may not love the answer. It's the honest one.

Why size is its own risk

A vault is a finite container. When you become a large share of it, three things go wrong at once, and all of them get worse the bigger you are.

You can't exit cleanly: to pay you out, the manager has to unwind a big chunk of the book, and in thin altcoin markets you sell against yourself for a worse price. You degrade the strategy: an edge that compounds on $100k often dies on $1M, because the trades that made the money no longer fit. And you become a single point of failure for everyone else in the vault. This is the whole reason the Index never holds more than 40% of any vault's capital — past that, you stop being an investor and start being the vault's problem. (If "how big is too big" feels abstract, read it through the lens of liquidity.)

So the Index doesn't just ask "is this vault good?" It asks "is it good, and can it absorb a real allocation without me wrecking it?" That second filter is what changes everything once you have size.

The uncomfortable arithmetic, on today's field

Here's the snapshot as I write this. The Index currently holds nine vaults. Add up the most each one can take — 40% of its capital — and the entire basket can absorb roughly $5.8 million before it would have to breach that cap somewhere.

That sounds like plenty. It isn't, because of how it's distributed. One vault — the single genuinely large open strategy on the board — accounts for about 88% of that capacity on its own. The other eight vaults, combined, can hold only about $700,000 between them. The investable corner of Hyperliquid today is one big vault and a scattering of small ones. That's not the Index's opinion; it's just the field.

How the Index actually behaves as your money grows

Because of that lopsided capacity, the Index quietly changes character as the money following it grows. It's a glide path, not a cliff:

• Up to ~$500k: genuinely diversified. The big vault is only ~14% of the basket; the small names carry the weight. This is the Index working as a fund of funds should.
• Around $1M: still an index, but tilting — the big vault is now roughly 30%, because the small ones are starting to fill up.
• Around $1.4M: the line. The big vault is about half the basket. Past here, calling it "diversified" starts to stretch the word.
• $2M and up: be honest with yourself — it's a position in one vault with a thin diversifying tail. By the $5.8M ceiling, it's ~88% that single name.

So, to answer the question in the title directly: if you want to invest more than about a million dollars today, the Altcopy Index behaves less like a basket and more like one large vault with garnish.

This is the rule telling you the truth

It would be easy to hide this. I could weight the Index by performance and show you a tidy, diversified-looking pie no matter how much money was behind it — right up until the day someone tried to actually deposit and found there was nowhere to put it. Plenty of products work exactly that way.

I'd rather the math embarrass me early than embarrass you late. The concentration isn't a flaw in the Index rule — it's the rule refusing to pretend a thin market is a deep one. The same honesty that makes the board recompute every number from scratch and flag the tiny-base mirages also forces it to admit when it simply can't diversify your size.

What to actually do with a million

Three honest options, depending on who you are:

• Accept the concentration. If you've done the work on the one large vault and you're comfortable, the Index at scale is essentially a high-conviction position in it. Just don't tell yourself it's diversified.
• Stay small per name, and be the whale on purpose. You can spread across the small vaults yourself, past the 40% line, accepting that you'll be a dominant holder and that exits will be slow. Sometimes that's a fine trade. Know that you're making it.
• Wait for the field to deepen. The Index re-derives every snapshot. The day a second large vault opens its doors, this entire glide path stretches, and a million diversifies comfortably again. Hyperliquid is young; this gets better with time, not worse.

This, by the way, is exactly the gap a future vault of vaults is meant to manage — sizing each allocation to what a vault can actually hold, and rotating as capacity opens up — so that following the Index at scale doesn't mean doing this arithmetic by hand. That's the road ahead, not today's reality.

For now, the most useful thing I can hand a large investor is an honest map of what the market can and can't absorb. That map is the live leaderboard — today's Index, today's capacity, recomputed from public data every day. Look at the TVL column with fresh eyes, and you'll see the whole problem in one glance.
