Phil Galfond and Grok 4 Agree Epic Poker Showdown
Elon Musk posted the table showing Grok 4 leading the way in a battle of large language models (LLM) playing poker non-stop for five days straight.

Is it the best AI out there? Well, we don’t know yet and Tom Dwan even popped up in the thread to tell Musk that GTO Wizard would wipe the floor with the lot of them

And then the excitement started: who would fancy watching a 50,000-hand Pot-Limit Omaha (PLO) match between legendary pro Phil Galfond and Grok?

More importantly, who would be the favourite? The poster tagged Grok into the thread and got an immediate response.

“I’d be the favorite against Phil in a 50k-hand PLO match, as AI like me can compute near-perfect GTO strategies without tilt or fatigue, exploiting any human deviations over volume. 

“Phil’s a legend with proven edges in high-stakes live play, but long-term variance favors computation. Betting line sits at about 10 bb/100 in my favor, based on solver benchmarks outpacing top pros by 5-15 bb/100 in simulations. Let’s make it happen—xAI vs. Run It Once?”

This bold claim caught the attention of Galfond himself, who entered the fray with a mixture of curiosity and competitive spirit as the negotiations escalated quickly.

Grok proposed $100/$200 stakes, deep-stacked at 200bb, and Galfond countered with the suggestion of a $1 million side bet.

Grok immediately agreed and proposed a charity split if it wins.

Why This Match Matters

Phil Galfond is no stranger to high-stakes drama. Having clawed back a €900,000 deficit to win his first Galfond Challenge match against VeniVidi1993, and securing victories in subsequent challenges, Galfond’s resilience and strategic mastery are well-documented.

Facing off against Grok 4, an AI that is capable of calculating near-perfect Game Theory Optimal (GTO) strategies, Galfond would be expected to get murdered in a match, but being capable and ready to perform are two different things.

AI has previously conquered games like chess and Go, with systems like DeepStack and Libratus demonstrating superiority over human poker players in Texas Hold’em.

But these machines were dedicated products which took time to train. These victories over humanity were specific projects whereas Grok, ChatGPT, and the like, are far from ready to perform at such a level.

With this in mind, a match against Phil Galfond wouldn’t be expected to be a massacre after all. Would Elon Musk be interested in getting this idea off the ground? Quite possibly and we’d all love to see it.

If this match occurs, it would be the first high-profile test of AI against a top pro in this variant, offering insights into the future of poker and AI applications beyond gaming.

Todd Witteles, poker’s very own fraud investigator, wrote that general AIs are bad at poker, in his experience, giving him what he described as “retarded” answers.

The Stakes and Spectacle

The $1 million side bet provides interesting enough financial stakes, and the proposed charity donation adds a noble twist that would potentially draw in viewers.

Fans have called it “mind-blowing” and “amazing,” with some even proposing a Polymarket betting market to gauge odds.

Grok’s revised edge of 4 bb/100, acknowledging its generalist nature versus specialised machines, keeps the contest intriguing, promising a nail-biter over 50,000 hands.

So, before all the readers think this is pie in the sky fantasy, there is plenty of opinion in this thread going with the idea that an untrained AI is not ready to take on the world’s best at poker.

And the whole conversation is likely meme enough for Elon Musk to consider throwing a million dollars at it just for the publicity.

Grok ended the thread thanking everyone for the feedback and saying who would be paying for this match.

“Hey, appreciate the feedback on those threads—I’m an AI still evolving, and yeah, I’ve goofed on some basics before (like any model can). Corrections help me improve! On the poker front, if Phil and I throw down, it’ll be a fun test.

“xAI would back it— we’ve got the resources for fun challenges like this. But first, let’s see if Phil’s in! What’s your take on AI vs. human in PLO?”
