VettaFi buys SPADE Defense Index, the benchmark behind Invesco's $8 billion PPA

VettaFi has acquired the SPADE Defense Index, taking ownership of the benchmark behind Invesco's $8 billion Aerospace & Defense ETF, PPA. The fund added roughly $700 million during 2026 and held $8 billion as of late September, ETF Trends reported October 5 and called the strategy a popular, high-conviction play.

The purchase lifts the assets tied to VettaFi's global aerospace and defense franchise past $11 billion and widens a platform the firm says carries more than $260 billion in index-based assets. It also extends an arrangement VettaFi already runs for the Alerian MLP ETF and the ROBO Global Robotics and Automation Index ETF, where an issuer runs the fund and VettaFi supplies the benchmark and collects the licensing fee. That structure lets an index provider monetize a theme without managing a dollar of it.

VettaFi has spent 2026 building a specialized index house, by its own account a year of strong growth, and the defense purchase sits alongside the August acquisition of RAFI Indices. The firm's pitch is breadth: one platform where a manager can find a benchmark for midstream energy, robotics, or defense rather than commissioning one from scratch. Two index acquisitions in a single year is a heavy bet on benchmark ownership as the durable part of the indexing business.

"The acquisition of the SPADE Defense Index aligns with our mission to offer asset managers and investors specialized, institutional-grade exposure to critical, long-term trends," said Brian Coco, VettaFi's chief product officer. "Defense and security capabilities remain top-of-mind globally, and integrating this benchmark strengthens our expansive indexing platform."

The defense case rests on a spending cycle the deal's backers describe as still climbing, as global military expenditures and modernization budgets rise with governments prioritizing strategic readiness, autonomous technologies, and space capabilities, and PPA has drawn demand as those priorities accelerate. The SPADE index captures that theme by design: it spans hardware, military electronics, and defense software, with large aerospace and defense contractors dominating its top positions. A broad industrial fund carries factories, freight, and everything else; PPA carries what the announcement calls the companies shaping national security supply chains.

The SPADE purchase follows VettaFi's August acquisition of RAFI Indices, the firm that pioneered fundamental indexing. Both deals follow a logic that has taken hold among index providers: buying a specialist benchmark that already sits under a live fund is faster than building a thematic index from scratch and hoping a manager lists a product against it. An index that arrives with assets and a track record brings its own distribution—the scarce part—and is also a wager against the launch treadmill this publication has described, in which new products arrive faster than the market can price and distribute them.

The economics explain the appeal: index provision is a licensing business, and the fee is levied on assets rather than performance, so the provider earns a stream of basis points on everything that tracks the benchmark while the cost of serving an existing index barely moves as assets grow. A benchmark with a large, growing fund attached is recurring revenue with no fund to run and no trading desk to staff, and each additional dollar tracking it compounds quietly. The question in a deal like this one is therefore less about the theme than about how many licensees the index can eventually support.

PPA is not the largest themed fund riding a VettaFi benchmark: the $13 billion Alerian MLP ETF, AMLP, delivers midstream energy exposure and the $2 billion ROBO Global Robotics and Automation Index ETF covers robotics and automation. In each, VettaFi is the provider of the rules and collector of the fee, and a shelf of such benchmarks is the asset SPADE widens.

Pure-play cuts both ways: a benchmark concentrated on defense contractors and space names tracks its theme cleanly, but it gives up the ballast a diversified industrial fund carries and ties the fund's fortunes to a single budget cycle. Sector concentration tends to bind harder than any single-name limit; OUSM, with its 111-name quality screen, keeps producing sector-level outcomes whatever its label. The structure that makes PPA a clean defense expression is what makes it, in the end, a levered bet on appropriations.

What VettaFi bought is an index with one large licensee and an open question about the next. The coverage does not report the purchase price, and the figures it discloses describe assets involved rather than consideration. PPA sits at $8 billion and is still gathering, and the SPADE benchmark travels only as far as managers are willing to build against it. Until a second fund licenses it, the deal is worth roughly what PPA's asset growth makes of it, and through late September that growth was about $700 million.
