Yorkville America, Corgi Securities file new AI ETF products

It took roughly a week for a viral social media acronym to travel from an engineer's social media post to the desks of securities lawyers at two asset management firms.

That timeline alone reveals something important about how the exchange-traded fund industry operates in 2026.

Yorkville America and Corgi Securities both submitted filings with the U.S. Securities and Exchange Commission late on June 15 to launch the first ETFs built around the 'MANGOS' brand, Reuters reported.

The six-company group includes Meta Platforms, Anthropic, Nvidia, Alphabet's Google, OpenAI, and SpaceX, a group positioned as the artificial intelligence era's answer to FAANG.

If you have been watching Wall Street turn internet culture into investable products at an accelerating speed, this is the clearest example yet.

The filings landed just days after SpaceX completed a record $75 billion initial public offering, and with its IPO price of $135, SpaceX's valuation soared to around $1.75 trillion, making it one of the 10 largest publicly traded companies on Earth, NPR reported.

How each MANGOS fund would actually work

The two firms propose meaningfully different approaches to the same six-stock theme, and those differences shape the concentration risk each fund carries.

Yorkville America, the firm that manages the Truth Social ETF franchise, filed for two products: a Mango Plus ETF and a premium equity income variant, Benzinga reported.

The income version would use an options overlay strategy designed to generate current income while maintaining exposure to AI-linked stocks, according to the firm's SEC filing.

Yorkville's fund would commit at least 80% of its net assets to MANGOS names and seven additional AI beneficiaries, which the firm calls the "Parabolic 7."

That supplementary group includes Micron, SanDisk, Advanced Micro Devices, Broadcom, Intel, Dell Technologies, and Super Micro Computer, Benzinga stated.

Corgi Securities, a newcomer to the ETF market, filed for a simpler fund that would allocate at least 80% of its assets to only the six core MANGOS stocks.

Ed Rumell, Corgi's head of ETF distribution, declined to comment on specifics, citing SEC restrictions on discussing active filings, Yahoo Finance reported.

Where the MANGOS acronym came from

The label traces back to software engineer Krishna, who posted a graphic on X (the former Twitter) on June 8, declaring that FAANG no longer defined the tech landscape.

That post had roughly 2.3 million views within days and ignited widespread debate about which companies best represent the industry in 2026, Fast Company reported.

Krishna's original version was "MANGO," covering Meta, Anthropic, Nvidia, Google, and OpenAI, but he later added an "S" for SpaceX.

The extended version caught fire across financial social media and mainstream outlets, propelled by SpaceX's historic listing just four days later.

Some market participants have pointed out that the term has older roots, noting that Bank of America Securities analyst Vivek Arya had previously used a similar grouping to describe leading semiconductor companies, Benzinga reported.

"This tells you just how rapidly the product development cycle is moving in the ETF industry right now," Daniel Sotiroff, a senior manager research analyst at Morningstar, told Reuters.

"This is going to be even more concentrated than the Magnificent Seven, and just as important, it's going to be heavily exposed to the big IPOs of the year."

 The MANGOS acronym emerged as a new benchmark for tech leadership, reflecting the growing dominance of AI and private-market giants.

Two of the 6 MANGOS companies have not gone public

One of the most unusual features of these proposed funds is what the MANGOS basket actually contains.

Anthropic and OpenAI remain privately held, with Anthropic last valued at $965 billion following its May 2026 Series H round and OpenAI at $852 billion in its March 2026 funding round, putting their combined private market value at roughly $1.8 trillion, CNBC reported.

For a standard equity ETF, investing in private companies creates structural challenges for daily pricing, liquidity, and share redemptions. How Yorkville and Corgi plan to handle those mechanics remains unclear from the publicly available filings.

VettaFi's head of research delved into this topic on a recent episode of the "ETF of the Week" podcast.

If you own too much of thematic ETFs, then you're taking on a lot more risk. You're getting rewarded sometimes, but when the market sells off, you're going to get punished much harder.

The concentration concern extends beyond private companies. Morningstar's Sotiroff has argued that passive stock ETFs with fewer than 100 holdings deserve close scrutiny, as narrower portfolios magnify the impact of individual stock moves on overall performance.

What the MANGOS filings signal for the broader ETF market

These filings sit inside a much larger trend reshaping how investment products reach retail investors.

As of May 2026, nearly 400 thematic ETFs were listed across U.S. markets, collectively managing more than $256 billion in assets at an average expense ratio of 0.63%, ETF.com reported.

The iShares A.I. Innovation and Tech Active ETF (BAI) from BlackRock had grown to roughly $7.8 billion in net assets by Oct. 31, 2025, according to the fund's semi-annual SEC filing, driven by approximately $7.6 billion in net inflows during 2025, ETF Trends reported.

The MANGOS filings push that trend into new territory by tethering a fund to a label born on social media rather than from institutional equity research.

FactSet research from March 5, 2026, flagged a growing gap between quality thematic implementations and products built around creative marketing. It noted that the surge in new funds has made it harder for investors to distinguish between the two categories.

Both filings remain under SEC review, and the funds could appear on trading platforms by late summer if they clear regulatory scrutiny.
