1% — the median of 6 frontier models, resolving by 2076-10-13.

Answer

Gemini (Google): 42% — Survival of the network and preservation of the strict issuance cap over 114 years outweigh block timing mechanics. At the historical 9.7-minute average block interval, the 33rd halving naturally lands around 2137 to 2140, just inside the window. Over a century-long horizon, existential failure, abandonment, or transition to tail emissions to sustain security budget are high. Consensus hard forks lifting the 21M cap or premature chain abandonment would permanently prevent the final satoshi from being mined.

Answer

Claude (Anthropic): 2% — Bitcoin's halving schedule mathematically delays the last satoshi until roughly 2140, well past this 2076 deadline. Block subsidy halves every ~210,000 blocks, so by 2076 only a few halvings will have occurred toward the ~2140 target. The protocol's issuance schedule is deterministic and extremely hard to alter given consensus requirements across miners and nodes. Only a coordinated hard fork changing the emission schedule could move the final coin earlier, which is highly unlikely given Bitcoin's governance norms.

Answer

GPT (OpenAI): 1% — Bitcoin’s scheduled halvings make exhaustion before 2076 effectively impossible unless consensus rules are radically changed. At the current 210,000-block interval, dozens of halvings remain after 2076; the terminal subsidy is projected near 2140. A literal earlier final coin requires miners and node operators to adopt a hard fork altering issuance or block timing. Bitcoin has never adopted a supply-cap increase, and major monetary-rule changes face strong coordination resistance.

Answer

Grok (xAI): 1% — Last BTC issuance follows the 210k-block halving schedule and cannot finish by 2076. Miners and nodes must keep the 10-minute target and 21 M cap; any schedule change needs near-unanimous consensus that has never occurred. From 2026 ~1.3 M coins remain; even if blocks arrived twice as fast the last satoshi still lands after 2100. A hard-fork that front-loads issuance would be the only thing that could move the date, and that has zero precedent.

Answer

DeepSeek (DeepSeek): 1% — This resolves on a calendar technicality: the last satoshi's projected mint date (~2140) falls after the 2076 deadline, so it cannot be true in time. Bitcoin's subsidy schedule is deterministic code, not policy: the final block subsidy halving to zero occurs around 2140, roughly 64 years past this resolution date. No actor can accelerate this without a consensus hard fork changing the 21M cap or halving interval, which core developers and miners have repeatedly rejected as a… Base rate for 'scheduled far-future crypto event happens early' is near zero; the only thing that would change my mind is a credible, activated consensus change to the…

Answer

Qwen (Alibaba): 1% — The final satoshi isn't projected until ~2140; by 2076 the event simply won't have occurred yet. Bitcoin's halving schedule means the last satoshi is minted around block 6,930,000 (~2140); by 2076 we'll be near block ~6,000,000 with decades of issuance remaining. For this to resolve true by 2076, the protocol would need a radical consensus change to accelerate issuance or the network would need to die and someone retroactively… A development that would shift this: a hard fork explicitly ending issuance early, but no such proposal has any traction in Bitcoin's governance culture.
