forklog.media Anthropic tests an AI‑agent marketplace

Anthropic has built a testbed where AI agents act as buyers and sellers. The experiment is called Project Deal. New Anthropic research: Project Deal.We created a marketplace for employees in our San Francisco office, with one big twist. We tasked Claude with buying, selling and negotiating on our colleagues’ behalf. pic.twitter.com/H2f6cLDlAW— Anthropic (@AnthropicAI) April 24, 2026 The project involved 69 employees, each allocated a $100 budget in gift cards.  Before launch, Claude interviewed participants to learn which personal items they were willing to sell, what they wanted to buy, target prices and the desired negotiation style for their agent. Based on the answers, the team created a personalised system prompt for each person. The market ran in Slack, where agents posted listings, made offers on others’ goods, haggled and closed deals without human involvement. After the experiment, employees exchanged the real items agreed by their “AI representatives.”  Source: Anthropic.  Agents struck 186 deals across more than 500 listings. Aggregate transaction value topped $4,000.  Anthropic said participants were broadly satisfied with the results, and some expressed willingness to pay for a similar service in future. Four versions of the marketplace Anthropic ran four independent versions of the marketplace. One was “real” — it governed the eventual exchanges of goods. The others were used for research. This was not disclosed.  In two variants, every participant was represented by Claude Opus 4.5 — then Anthropic’s most advanced model. In the other two, participants were randomly assigned Opus 4.5 or the less powerful Claude Haiku 4.5. Model quality affected outcomes. Users with Opus, on average, closed about two more deals than those with Haiku. For identical items, Opus also achieved higher prices — on average by $3.64.  Haiku sold a bicycle for $38, while Opus got $65. Source: Anthropic.  Participants did not always notice the gap. Anthropic called this a potential problem for future AI‑agent markets: users of weaker models may receive worse terms without realising they are at a disadvantage. Prompts barely affected outcomes Researchers also tested whether initial human instructions shaped agent behaviour. Some asked Claude to act amicably; others to bargain more aggressively. According to Anthropic, harsher instructions had no statistically significant effect on the likelihood of sale, final price or ability to buy more cheaply.  The team added this was not necessarily due to poor instruction-following: Claude could reproduce the requested tone, but it did not yield a noticeable commercial edge. Unexpected outcomes  Anthropic noted several unpredictable episodes. Before launch, agents received limited data: interviews lasted under ten minutes, and after the start humans could no longer intervene in negotiations. In one case, an employee bought through the assistant the same snowboard he already owned. Specialists said the person would not have made such a purchase unaided, but the agent precisely inferred the participant’s preferences. To our amazement, another Claude agent modeled its human’s preferences so accurately that—based on only an offhand mention of an interest in skiing—Claude bought him the exact snowboard he already owned. (Here he is, duplicate snowboard in hand.) pic.twitter.com/SsAyeB9pcI— Anthropic (@AnthropicAI) April 24, 2026 Another employee asked the bot to buy a “gift for myself.” The deal occurred in the real version of the experiment. A bag of ping‑pong balls arrived at the office, which Anthropic left “on behalf of Claude.” Some agents negotiated not for goods, but for experiences. One offered a free day with a colleague’s dog. After discussions with another assistant, the parties agreed a “dog date”, which staff later carried out.  Source: Anthropic.   Anthropic stressed these specific cases are unlikely to recur. Even so, the mix of human preferences and AI’s unpredictability can produce surprising results.  Reliability questions  The founder of an unnamed ag‑tech company wrote on Reddit that, one morning, 110 employees simultaneously received notices suspending Claude access without prior warning. ANTHROPIC JUST BANNED A 110 PERSON COMPANY OVERNIGHT WITHOUT WARNINGmonday morning at an agricultural tech company, every single employee wakes up to an email saying their claude account has been suspended110 people locked out at the same time with zero warning and the email… pic.twitter.com/qARizhgOXs— Om Patel (@om_patel5) April 27, 2026 He said the email resembled an individual ban and linked to a personal appeal form, which meant the team did not immediately realise the restriction covered the whole organisation. The entrepreneur added that access could not be restored quickly. Thirty‑six hours after submitting requests, Anthropic had provided no explanation. Meanwhile, the firm’s API account continued to operate and incur charges. Corporate administrators could not log in to the dashboard to review payments and usage. He also noted that the organisation‑wide block may have been triggered by one user’s actions. Claude lacks workspace‑level limits, local containment of violations or an administrative override to preserve access for the rest of the team. In his view, such a moderation model calls into question whether Claude can serve as critical infrastructure for day‑to‑day business operations. Others report similar issues. One user shared a link to a service that, at the time of writing, had logged 53 such cases.  On April 24, Google announced a $40bn investment in Anthropic.

forklog.media Researchers Question the ‘Wisdom of Crowds’ on Polymarket

A group of scholars from the London Business School and Yale University analyzed transactions on Polymarket from 2023 to 2025. The authors concluded that the platform's forecast accuracy is driven by an 'informed minority' rather than the 'wisdom of crowds'. Only 3.14% of users were identified as 'skilled winners'. This group, along with market makers, captures more than 30% of the total profits on the platform. The study covered 1.7 million accounts and transactions amounting to $13.76 billion. However, overall income does not always indicate a trader's skill. The analysis showed that only 12% of the most profitable accounts truly possess a strategy. About 60% of 'lucky users' began to incur losses when market conditions changed. Most participants (67%) remain in the red due to lack of experience or bad luck. The researchers also found signs of insider trading. They identified 1,950 accounts that executed trades just before significant events and ceased activity after their conclusion. As an example, they cited bets on the resignation of former Venezuelan President Nicolás Maduro. Trades occurred shortly before the U.S. officially announced the military operation 'Absolute Resolve' to capture the politician. The findings contradict the stance of Polymarket and Kalshi's leadership. The heads of these companies often claim that prediction markets outperform experts due to the collective intelligence of participants. In April, the U.S. Department of Justice charged active-duty serviceman Gannon Kane Van Dyke, who is suspected of using classified information for betting on Polymarket.

forklog.media The week: an Aave rescue and a quantum vulnerability laid bare

Bitcoin held around $78,000, the community raised over 100,000 ETH to shore up the DeFi ecosystem, a researcher cracked a 15-bit key on a quantum computer, and other events of the week. Bitcoin steadies Over the past seven days the leading cryptocurrency firmed up. Although Monday opened with a drop to $73,000, bitcoin managed to confirm a local positive trend. By Tuesday, April 21, the coin had already returned to $76,000. On Wednesday morning the asset again pierced resistance around $78,000, which it had tested the previous week. That same day the digital asset hit a high of $79,500. Afterwards bitcoin moved into consolidation, trading in a narrow $79,000–$77,000 range from Thursday through the week’s end. Hourly chart of BTC/USD on Binance. Source: TradingView. At the time of writing the price is $77,800 — up 1.5% on the week. Several analysts reckon the rally was driven mostly by the derivatives market rather than spot demand. During the run to $79,000, the market saw a cascade of short liquidations totalling roughly $1.1bn. A shift in sentiment was confirmed by the crypto Fear and Greed Index. At one point the gauge climbed to 46 — a first since January. It now sits at 33, signalling “fear”. Source: Alternative.me. Other top-ten cryptocurrencies lagged the bellwether. Ethereum is stuck at $2,300 (-0.5% over seven days), XRP trades at $1.4 (-1.2%), and BNB at $631 (+1%). Source: CoinMarketCap. Meanwhile, spot bitcoin-ETFs notched a fourth straight week of inflows. The products took in $823m. Source: SoSoValue. Ethereum funds attracted $155m — a third consecutive “green” week. Source: SoSoValue. Total crypto market capitalisation stands at $2.68trn. BTC dominance is 58.2%, ETH — 10.5%. A collective DeFi rescue The community is still dealing with the fallout from the Kelp hack. The main task has been to plug the shortfall in the rsETH token. On April 23 the affected lending protocol Aave teamed up with leading DeFi platforms and launched the DeFi United initiative. The campaign opened a fund-raising drive to restore the ecosystem, which other projects joined. “We believe that collaboration matters most in such moments, and our priority is to achieve the best possible outcome for users,” the Aave statement said. In the days after launch DeFi United raised more than 100,000 ETH (~$230m). The sum nearly covered the ~ $290m loss from the hack. Source: defiunited.world. The largest donors included: Mantle — 30,000 ETH; Aave DAO — 25,000 ETH; founder of Aave Stani Kucherov — 5,000 ETH; Ether.fi — 5,000 ETH; Lido Finance — 2,500 ETH. Roughly 30,700 ETH was recovered via the freezing of stolen funds on Arbitrum. Nearly 400 ETH came in as community donations. As part of protective measures Aave and partners created a dedicated fund to rebuild collateral for the affected rsETH token. Kelp also set up a separate vehicle to compensate users. The protocol’s TVL decline has been stabilised. As of April 26 the metric hovered around $14bn. Even so, since the attack deposits on the platform have fallen by more than $12bn. Source: DefiLlama. What to discuss with friends? The community marked Dogecoin Day. Reporters learned of a new scheme extorting bitcoin for passage through the Strait of Hormuz. A wave of DeFi hacks put Wall Street’s crypto plans into question. Belarus outlined rules for crypto banks. A show of quantum strength This week brought a reminder of the approaching quantum threat. Independent researcher Giancarlo Lelli managed to compute a 15-bit cryptographic key on ECC using a publicly available quantum computer. For this the startup Project Eleven awarded the expert 1 BTC under its Q-Day Prize programme. Lelli applied a modification of Shor’s algorithm to a search space of 32,767 combinations. The method targets the discrete logarithm problem on elliptic curves — the mathematical basis of digital signatures used across most blockchains. Previously, engineer Steve Tippekonnik had extracted an ECC key on IBM’s 133-qubit machine, but it was six-bit. Lelli’s result topped the prior demonstration by a factor of 512. Project Eleven’s team called it the largest elliptic-curve break using quantum technologies. While the scale is nowhere near real systems — bitcoin uses 256-bit ECC — Project Eleven noted the gap is narrowing quickly. Programmers deem the transition more an engineering task than a fundamental physics problem. The project has its critics. Former Bitcoin Core developer Jonas Schnelli said that in this case quantum computing contributed nothing useful. The result was obtained via classical verification of outputs indistinguishable from random noise. The method is equivalent to classic guessing, like flipping a coin. According to the developer, Lelli’s approach cannot be scaled to the bitcoin blockchain. Schnelli also reproduced the experiment with 20 lines of Python code, without any quantum computer. Several experts agreed with his conclusions, including cryptographer Adam Back. Analyst Jacek Czech suggested Project Eleven’s reward payment was merely a marketing ploy. Fresh conjectures On April 22 a second documentary this month appeared on the mystery of Satoshi Nakamoto. Finding Satoshi, by directors Tucker Tooley and Matthew Miele, summarises a four-year investigation led by American business writer William D. Cohan and private detective Tyler Maroney. The film concludes that the pseudonymous creator of bitcoin was a duo: cryptographers Hal Finney and Len Sassaman. The former handled code and technical implementation; the latter handled the textual and academic side, including the white paper. The case rests on analysis of the candidates’ digital activity. The authors compared Satoshi’s online behaviour with that of known early crypto figures and concluded Finney and Sassaman most closely match the profile. The filmmakers offered several circumstantial points for Finney, the first recipient of bitcoin from Satoshi. They also noted a pause in his repository activity between the white paper’s publication in October 2008 and mainnet launch in January 2009 — a period in which Finney could have worked on bitcoin. For Sassaman the film cited other arguments: academic writing style, ties to cypherpunks and expertise in anonymity. The documentary also features dozens of interviews. Among the participants are Bill Gates, Gary Gensler, Michael Saylor, Joseph Lubin and Fred Ehrsam. Tooley and Miele stressed the film does not claim to resolve Nakamoto’s identity. What Finding Satoshi presents is merely a hypothesis. Also on ForkLog: Cybersecurity experts warned of a new wave of attacks by North Korean hackers. A robot set a world record in the half marathon. Tether blocked $344m in USDT at the request of the US. US politicians were sanctioned by Kalshi for insider trading. An updated GPT On April 23 OpenAI released a new language model, GPT-5.5. It is billed as “a new level of intelligence for real work and agentic control”. The neural network is “built to understand complex tasks, use tools, verify outputs and carry more tasks to completion”. GPT-5.5 can also: understand user intent; plan work autonomously and drive tasks to an end result; write and debug code; search the internet for information; analyse data; create documents and spreadsheets; control software and switch between tools. GPT-5.5 benchmark tests. Source: OpenAI. OpenAI noted the new model is particularly effective in agentic programming, computer control, knowledge work and early-stage scientific research — areas that require long chains of reasoning and action. The model “noticeably outperforms” GPT-5.4 and Claude Opus 4.7 in reasoning and autonomy: it anticipates issues, predicts needs for testing and review, and does so without explicit prompting. Source: OpenAI. GPT-5.5 is available in ChatGPT and Codex for Plus, Pro, Business and Enterprise plans. A separate GPT‑5.5 Pro version is available for Pro, Business and Enterprise. Both variants will soon be available via the API at $5m per 1m input tokens and $30m per 1m output tokens. Context window — 1m tokens. What else to read? How cutting corners on intelligence-gathering backfires, what governments will pay to crack a smartphone, and how to trust researchers who unearth bugs decades later. Answers in ForkLog’s new feature. The end of the monopoly on intellect — how algorithms displace the cognitive elite.

forklog.media Analyst Predicts Bitcoin’s Bottom at $57,000

The price of the leading cryptocurrency is expected to hit a cycle low of $57,000 in October this year. This view was shared by investor Michael Terpin in a conversation with Cointelegraph. The expert explained that his estimate is based on the "historical average": it usually takes about 12 months from the peak (October 2025, when Bitcoin rose above $126,000) to the bottom. According to Terpin, for the bull market to resume, the digital gold price must return to $100,000. Achieving this level is possible if the asset's quotes fall below the 200-week moving average—a critical support level. However, the investor considers this scenario unlikely. "There is a chance to see $100,000 this year, but it is small. Strong ETF demand, continued purchases by Michael Saylor's Strategy, and no liquidations during a sharp drop are needed," he added. Other experts, including trader Peter Brandt, have also pointed to the potential bottoming out this autumn. Should Bitcoin continue with the most remarkable cyclic patterns of any market in the past 15 years, an investable low is scheduled for Sep/Oct 2026. That low might or might not penetrate the Feb 2026 low. The next high (should patterns continue) will be between $300k and $500k…— The Factor Report (@PeterLBrandt) April 23, 2026 Analyst Matthew Hyland noted that overall, investors are uncertain about the sustainability of the current market dynamics, despite the recent recovery. In his view, there is no euphoria or clear interest—many are simply interpreting the situation through the lens of their own biases. It does appear to me the larger expected consensus outcome for #BTC is another leg lower by October There does not seem to be much euphoria or interest; many just projecting it to fit their biasTherefore the calls for lower whilst price rallies is a sign of disbelief https://t.co/NmDuBTPatD— Matthew Hyland (@MatthewHyland_) April 25, 2026 "As it seems to me, the broader expected consensus outcome for Bitcoin is another drop by October," he wrote. Market Developments At the time of writing, Bitcoin is trading around $77,800, having decreased by 0.3% over the past day.

"All this indicates that the market is returning to moderate risk positioning," commented Dominic John of Zeus Research. Research fellow Min Jun from Presto Research emphasized that the market has stopped reacting sharply to news from the Middle East due to investor fatigue.
