The Cap That Didn't Bite

On Tuesday, Palantir went up 29.45% in a single session.

PLTY — the YieldMax fund that sells options on Palantir, the one whose entire category is defined by giving away the upside — went up 26.22%.

That’s 89% of the move. From a fund that is supposed to cap exactly this.

I’ve been holding PLTY since November and I’ve written before about how these things actually work. I still had to go read the holdings twice. Because if your mental model of a covered-call ETF is the one everybody has — own the shares, sell calls against them, collect premium, eat a ceiling — then Tuesday shouldn’t have been possible.

It was possible. And the reason is more interesting than the number.

The receipt

Palantir reported Q2 after the close on August 3rd. Revenue $1.94B, up 93% year over year. EPS $0.41 against $0.33 expected. U.S. commercial revenue up 149%. Full-year guidance raised to $8.15B. The kind of quarter that doesn’t leave much room for argument.

No distribution came out in between, so that’s a clean price-to-price comparison — PLTY pays weekly, and its ex-date that week fell on the other side of the print. And this wasn’t the market bidding the fund to some silly premium either: PLTY’s published NAV came in at $36.77 against that $36.39 close. The fund’s own books moved. The gain was real.

Capture ratio: 89%.

For a product whose prospectus says, in so many words, that it “will capture only a portion of its potential gains if PLTR’s price increases,” 89% is not a portion. That’s most of it.

What everybody thinks is in the box

The phrase “covered call ETF” does a lot of damage.

It puts a picture in your head: a pile of Palantir shares sitting in a vault, and a manager selling call options against them every month. Under that model, the math on Tuesday is brutal and obvious. You sold someone the right to buy your shares at, say, $138. The stock went to $162.66. You participate up to $138, you pocket the premium, and you watch the other $24 walk out the door with the guy who bought your call.

You’d expect maybe half the move. Two-thirds if the premium was fat.

You would not expect 89%.

So I opened the box

Here is what PLTY actually held, from the fund’s own holdings page, as of August 5th. Net assets: $382.4M.

Notice what isn’t there.

There are no Palantir shares. Not one. Same story as MSTY — 84.5% of the fund is Treasury bills, and the Treasuries are the fuel tank, not the destination. The actual Palantir exposure is built entirely out of long call options.

And notice something else: every option line is a long position. Where are the calls this thing is famous for selling?

They’re there. They’re just not on the page.

Add it up: $323.19M of T-bills plus $143.24M of long calls is $466.4M of assets — against $382.4M of net assets. The difference is about −$84M, and that’s the written side of the book. Roughly 22% of NAV in short calls that the holdings table doesn’t bother to display.

Reason one: it isn’t a covered call fund anymore

This is the part that made me sit up.

YieldMax has quietly moved off plain covered calls. Their own primer on the change is titled Enhanced Covered Call Strategies Using Credit Spreads, and PLTY’s materials now describe a call spread writing strategy. The document is refreshingly blunt about the trade:

“Instead of only selling a call, you also buy a higher strike call. This creates a call spread, which lowers your premium income but limits the risk of capped gains if the stock surges.”

Their own worked example, on a $50 stock:

Read that table twice, because it’s the whole product. Half the income. In exchange, the payoff diagram stops being a flat line at the strike and starts climbing again above the long call.

A covered call sells one option, and that option is naked to the upside — the higher the stock goes, the more it costs you, forever. A call spread sells one option and buys a further-out one against it. Your loss on the written side stops at the width of the spread. Palantir going to $162 instead of $150 doesn’t cost the spread anything extra once it’s blown through both strikes.

Under the old structure, a 29% gap is an unbounded bleed on the short leg. Under a spread, the damage is a known, finite number that was fully priced in the moment the trade went on.

The ceiling didn’t disappear. It just stopped being a ceiling and became a step.

Reason two: the base is bigger than the fund

Count the contracts: 12,491 + 10,418 + 8,573 + 10,890 + 4,500 = 46,872 long calls. Each one controls 100 shares. That’s 4.69 million shares of Palantir exposure.

At Palantir’s pre-earnings $125.65, that’s $589M of notional sitting on top of $382M of net assets — about 154%.

Now, that’s the gross figure, and the written calls net off a real chunk of it, so don’t read “1.5x leveraged fund” into it. But the direction is the whole point. When you build exposure out of options instead of shares, the premium is a fraction of the notional, so a fund holding $382M can carry a base far larger than one share of PLTR per dollar of NAV. The cap applies to a slice of that base — not to the base itself.

Cap 30% of an oversized position and you can still clear most of a 29% day.

Reason three: it’s a ladder, not a wall

Look at the expiries again: August 7th, August 21st, September 18th. Strikes at 127, 129, 130, 135, 140.

That is not one trade. That’s a rolling book of them, staggered across three expiries and five strikes, put on at different times as Palantir drifted around $120–130 in the weeks before the print.

A single-strike covered call is a wall — the stock hits it and everything above is gone. A ladder is a series of speed bumps at different distances. A gap that clears all of them still leaves every long leg deep in the money, where each one moves nearly dollar-for-dollar with the stock. Those $127 and $129 calls expiring August 7th went from barely in the money to $35 in the money overnight. At that depth they behave like stock.

Reason four: the volatility crush works for the seller

The last piece is the one nobody outside options world thinks about.

Going into the print, Palantir options were priced for roughly a 12% move. That’s expensive. Every call the fund had written was stuffed with time value.

Then Palantir reported, the uncertainty resolved, and implied volatility collapsed — it always does. The fund is a net seller of that time value. So on the written legs, even the ones that went in the money, a large chunk of the extrinsic value the fund was short simply evaporated overnight. The intrinsic loss was real. The time-value gain partly paid for it.

This is the actual engine of the whole product, and it’s the one honest thing about it: these funds get paid to absorb volatility. Tuesday was a day when absorbing it happened to work out.

Now the honest half

If you’ve read anything else here you know what comes next, because a post that stopped at “look how well my fund did” would be exactly the kind of thing this site exists to not be.

The same structure that caught 89% on Tuesday is why the position is a loser.

Here’s my actual PLTY position, opened November 13th, 2025 on a defense-and-intelligence-demand thesis, as of today — after the 26% pop:

Down 36% on price. Down 6.8% counting every dividend. And that’s the good version — before Tuesday this position was −46% on price and −18% all-in. One of the best days a single-stock income fund has ever had moved me from “bad” to “still losing.”

The trailing twelve-month yield is 98.8%. The implied NAV decay is about 61% a year. Those two numbers are the same number wearing different clothes, and that is the trade: the fund converts its own share price into distributions and hands them to you. Leverage that catches 89% of a moonshot catches the same share of everything going the other way, and Palantir spent most of the last nine months going the other way. Palantir closed at an all-time high of $207.18 back on November 3rd, 2025. Even after a 29% melt-up, it closed Wednesday at $158.43.

I’ve written before that NAV decay is rust. Tuesday didn’t repeal it. It just gave the rust a very good day.

The takeaway

The thing I actually want you to take from this isn’t about Palantir, and it certainly isn’t “PLTY is better than you thought.”

It’s that the label on the fund is not a description of what’s inside it.

“Covered call ETF” is a category name someone at a marketing desk chose. What’s actually in PLTY is a Treasury collateral pool, a laddered book of long calls carrying more notional than the fund has assets, and a written overlay that is a spread rather than a naked short. Those are four different decisions, none of which is visible in the words “covered call,” and all of which determine what happens to your money on a day like Tuesday.

Everybody who was confident PLTY would badly lag that rally was reasoning from the label. The holdings page is free, it’s published daily, and it took me about ten minutes to find the $84M that wasn’t on it.

Read the holdings. Then form the opinion.
