NBA champion Tristan Thompson on investing in Prometheus, running SPVs, and the future of AI in sports

Tristan Thompson on investing, SPVs, and physical AI

Tristan Thompson is 13 seasons into an NBA career and increasingly focused on what comes next. He frames the transition plainly: same hunger, different uniform — "instead of wearing a jersey, I'm wearing a Tom Ford suit."

His entry into alternative assets came after his second NBA contract, an $82 million deal, when he switched financial advisors and started moving beyond the Fidelity and Wells Fargo defaults. Early exposure came through Morgan Stanley, which gave him access to vehicles like Carlyle Group. From there, he moved toward direct founder relationships and peer-sourced deal flow.

Betting on founders

Thompson's investment thesis centers on the founder over the product. Pitch decks, he notes, used to promise $100M and now promise a billion — the numbers have inflated but the signal hasn't. His filter is borrowed partly from peers who were early in Ethereum and had early Coinbase access: go into 10 deals expecting eight to fail, and size the two winners to cover the book.

He's deliberate about concentration. When he commits to a category — robotics, drones, tech — he wants one or two positions, not ten. For investments where he believes in the GTM story, he'll work the narrative publicly. For others, he stays quiet until the return justifies the visibility.

“I always bet on the founder. It's betting on the horse. I've been running a lot of SPVs the last two years — one thing I'm very bullish on is Prometheus and I just invested in their last round. My thesis on robotics right now — Jensen Wong said it two years ago — it's about physical AI. Whether it's healthcare, agricultural, construction, landscaping, robots and robotics can help.”

SPVs and a possible fund

Thompson has been running SPVs for the past two years. His most recent allocation is in Prometheus, which he describes as a robotics and warehouse automation play — specifically the kind of robotic arm work Amazon relies on for packaging, not just autonomous vehicles. He accessed the Prometheus friends-and-family round and pushed that allocation out to his network.

He's considering launching a formal fund around Q4, structured to give fellow players and global contacts the same deal access he has. He's also had meetings with the Qatar Investment Authority (QIA), which he says has been receptive. The accelerator idea is also on the table — he floats a hypothetical co-investment structure with Y Combinator, splitting the $250K check and the equity stake.

Physical AI and agriculture

Thompson is bullish on physical AI — Jensen Huang's framing, which he adopts directly. He's skeptical that humanoids are ready for consumer or home use but sees near-term value in agriculture, healthcare, construction, and logistics. His sharpest point is on farming: labor shortages are squeezing margins, and autonomous machines let owners focus on the business rather than the headcount. He sees this as underloved relative to the AI energy and data center conversation.

AI in sports

On the officiating side, Thompson wants a fourth referee powered by AI, pointing to tennis and football's VAR system as proof of concept. His practical grievance is specific: a charge/block call against LeBron James in Game 1 of a series against Golden State that he argues turned the series. On the player health side, he points to Jayson Tatum, Tyrese Haliburton, and Damian Lillard all tearing their Achilles in last year's playoffs as the forcing function for Adam Silver to take sports science AI seriously.

The NBA's player income plan

Thompson raises an internal NBA program — the Player Post-Career Income Plan — where players contribute a portion of each paycheck to a custodial account that pays out monthly after retirement to bridge them to age 55 or 60. His frustration is that the capital earns no yield for the player. Someone is getting that yield, he implies, and it isn't the athletes. He contrasts this with the NBA's 401(k) match, which he credits at 120 cents on the dollar — genuinely strong by any benchmark. His pitch is that even a portion of that pooled post-career capital could be deployed into something like a SpaceX allocation rather than sitting idle.

---

Thompson is still figuring out the structure — SPV operator, fund manager, or accelerator co-founder — but the direction is consistent: use the access and platform he has to pull other players into deals earlier, before the 25x is public and the window is closed.
