Y Combinator to wire $500k in 'whichever stablecoin still pegs by demo day'

Y Combinator will begin wiring its standard $500,000 investment in “whichever stablecoin still pegs by demo day,” according to an internal memo circulated to founders enrolled in its latest batch.

“If no stablecoin is within 15% of $1, the memo says the investment will be made in “YC Meal Credits, redeemable for office snacks and drip coffee at participating locations.””

The move formalizes the accelerator’s first broad-based exposure to what it described as “dollar-adjacent digital cash instruments,” and replaces the default practice of wiring U.S. dollars or a single pre-selected stablecoin.

Under the new framework, YC will deposit funds into a diversified pool of 17 dollar-pegged assets, ranging from major issuers to what the memo called “emerging regulatory curiosities,” then convert the entire amount into whichever one is “closest to $1.00 at the time of each company’s demo day slot.”

“The goal is to back founders while remaining neutral on which stablecoin survives the quarter,” a YC spokesperson said, adding that a proprietary “Peg Resilience Index” will determine eligibility.

Analysts at JPMorgan, in a note titled “Who’s Still at $1.00?”, said that from 2020 to 2024, 63% of the top 20 stablecoins by volume spent at least 20 consecutive minutes off their peg, with a median drift of 4.7%.

They estimated YC’s approach could reduce single-issuer risk by 82%, while increasing “narrative volatility” in investor update emails by approximately 240%.

Several founders in the current YC batch said the new policy had already influenced their treasury strategies, with one crypto infrastructure CEO confirming they now run weekly simulations of outcomes ranging from “USDC at $0.91” to “our entire round arriving in a token that only trades on one Bulgarian exchange during local business hours.”

“We’re basically long YC’s ability to guess which synthetic dollar won’t explode before we ship,” the founder said.

Stablecoin issuers privately welcomed the change, with one major player proposing a marketing partnership to temporarily re-peg its token to “1 YC-backed startup share” during demo day week, according to a person familiar with the discussions.

Regulators are “monitoring developments with routine bewilderment,” an SEC staff attorney said, noting that any formal guidance would likely follow “a 4,000-page risk disclosure, two partial government shutdowns and at least one stablecoin obituary.”

YC has created a Peg Review Committee that will meet hourly during demo day to track live prices, blockchain congestion and what the memo describes as “vibe-adjusted depeg risk,” backed by a dashboard that refreshes every 11 seconds and runs 3,200 probabilistic collapse scenarios per startup.

If, at the time of a company’s presentation, no stablecoin is within 15% of $1, the memo says the investment will be made in “YC Meal Credits, redeemable for office snacks and drip coffee at participating locations.”

The accelerator is also exploring extending the model to future batches by wiring funds on “whichever L2 hasn’t halted for upgrades that morning,” and piloting SAFEs indexed to the “continued operational status of global payment systems.”

According to the memo, YC ultimately aims to “modernize early-stage financing so that founders are not merely building against market risk, but against the ongoing viability of money itself.”
