Lightcone Infrastructure’s listed projects include LessWrong and Lighthaven. LessWrong supplies a durable home for arguments and discussion; Lighthaven supplies physical space. Together they form part of the environment in which people working on AI risk, rationality and related projects encounter one another and develop ideas. That practical infrastructure is its main role in this investigation.
The property story involves a large financing commitment. In March 2023, Oliver Habryka described a $20 million loan from Tallinn-owned Slimrock Investments Pte. Ltd., comprising $16.5 million for purchase and $3.5 million for renovations. Lightcone’s December 2025 fundraiser discussed mortgage servicing. A campus therefore appears in the graph through a continuing obligation as well as a community benefit.
A separate arrangement followed an FTX settlement. The 2025 fundraiser described a $1.7 million arrangement involving Tallinn and Survival and Flourishing Corp., with half of later grant recommendations withheld until $1.29 million had been offset. This connects future support to an earlier financing solution and makes the dependence more specific than the general observation that a donor supports an organization.
The organization’s significance is the combination of community infrastructure and the financial commitments required to maintain it. People can gain a forum, colleagues, visibility and working space through those resources. The network should consequently show the operators and funding obligations behind that environment alongside the writers and advocates whose work circulates through it.
Lightcone Commons coordinates donors and evaluators using a funding-allocation process adapted from SFF and Lightspeed Grants. Habryka is CEO and a confirmed evaluator. Platform fees and evaluator compensation make the funding service economically explicit.
The Corrigibility Research Fund identifies Lightcone Infrastructure Inc. as legal grantmaker and final approver. This is a documented responsibility beyond providing a platform.

From the investigation
A community, a book and a production channel
LessWrong's own history identifies Yudkowsky as its founder in 2009 and describes his writings as part of its philosophical foundation. Its FAQ records that the site began as MIRI property. Today, Lightcone Infrastructure lists LessWrong among the infrastructure it operates. This is a documented genealogy; it does not establish that Yudkowsky currently controls Lightcone.

Lightcone Commons is operated by Lightcone Infrastructure, the organization behind LessWrong and Lighthaven. It is distinct from the similarly named Lightcone Foundation already in the investigation.
Read the research & sources ↗Who can actually authorize a grant?
A smaller programme supplies a completed example. The Corrigibility Research Fund names Lightcone Infrastructure Inc. as its legal grantmaker and final approver. Max Harms manages the fund. On September 3 he announced eight awards totalling $132,000, following more than 100 applications, and directed future applicants to Commons. Ian Kahn was awarded $35,000 and Ben Saudek $3,000; Harms says both first contacted him after his appearance on the 80,000 Hours podcast. Here is a visible sequence from public communication to professional contact to funding. Fund structure , awards
