As someone newer to finance, I've found one the most interesting -- and challenging -- things is to create a new, creative financial structure. In general, (1) people are risk-averse and complexity-averse, especially when it comes to money, and so (2) financial institutions are good at providing shades of the same exact service with little innovation. Much of the financial system seem to be building and retaining trust, not coming up with cool new ways to build companies or structure deals.
The interesting things happen at the margins, by people who have the political capital and financial savvy to take risks. I think David Swensen and the Yale endowment embody accretive creativity -- and how these novel structures can only last so long. To me, Swensen's real genius was that he had a gut feel of the nuts and bolts of the financial markets, and a willingness (and persuasiveness) to try new things. In his short stint on Wall Street, he helped structure the first swap (something that is now commonplace and thus less profitable today). He was one of the first to see that Yale's endowment portfolio -- a majority stocks, bonds, and cash in the 80s -- could benefit from (a) the long-time horizon of venture capital and private equity, (b) the undiscovered-ness of these alternative asset classes, and (c) the diversifying ability of the asset classes. Like the swap, this Yale Model attracted initial good returns, which attracted imitators, which means more competition and lower returns. Regardless, these types of innovations (swaps, the Yale endowment model) seem to be structural ways for investors to have a temporary edge (and thus "alpha").
I've been keeping mental notes of these in the past couple years, and I figured it's worth putting them somewhere. I hope to add to this list as I see things, but I hope this will be a nice throughline to follow for the decades to come.
(1) Trump Media Discovers Nuclear Fusion - Bloomberg - What makes Matt Levine's Money Stuff column so great is that he has a knack for taking the most banal news snippets, breaking them down into simple terms, and then viewing them through a lens of incredulity. In this Dec 18, 2025 write-up, Trump Media (DJT) proposed a merger with TAE Technologies, a fusion power company. Through the popular media lens, this is just a money grab. But Matt Levine's take is more interesting (and les political): fundraising is hard, but meme stocks (like DJT) are incredible at it. What if more meme companies (cash-rich) acquired generally good businesses who are short on cash -- is that a win-win? It feels almost SPAC-like, and perhaps a new way for meme stock businesses to convert Reddit hype into future cash flows.
(2) New models of VC - In the canonical VC company, the fund invests in 30 seed-stage investments, hoping that one will return 100+ times, fueling the majority of the fund's performance (i.e. the "power law"). As VC has grown as an asset class, VCs have experimented with new models, including accelerators (e.g. Y-Combinator), incubators (e.g. Flagship Pioneering), asset class specialists (e.g. Electric Capital), celebrity-to-get-access VCs (e.g. Kevin Durant's 35V, Chainsmokers' Mantic VC), and alumni-affiliation-to-get-access (e.g. Alumni Ventures).
As venture funds have gotten massive ($5B in Thrive's latest fund), Thrive (and other VCs) have opted for "AI roll-ups," acquiring multiple companies in a sector and infusing them with AI. It feels like a mash-up of a PE fund and an AI incubator with hints of ETA (entrepreneurship through acquisition), and it's changed what the VC firms look like, too (e.g. larger investments in product/engineering teams). It (a) represents an interesting new model of VC... but (b) it's quickly gone mainstream (e.g. at General Catalyst, Lightspeed, 8VC). Perhaps it means the idea isn't that new after all; or that venture firms are nimble, reducing the time to test new ideas; or that this is one of the only ways to deploy all of a multi-billion-dollar venture fund. In other words, it's still early to tell if this approach will be a winner, or if this organizational/structural alpha has already been eroded.
