Bitcoin as collateral, bStocks past $1 billion, and a 75% bailout call: October 11-18, 2026

From October 11, 2026 at 6:00 p.m. through October 18, 2026 at 6:00 p.m. in UTC-05:00, crypto traded two stories at once. On October 14 the Bureau of Labor Statistics reported September consumer prices up 0.6% for the month and 3.7% over the year, with gasoline up 9.1% and accounting for more than half the monthly increase. 1 The next morning an AI-infrastructure selloff took bitcoin to $79,950, its first trip below $80,000 since mid-September, before buyers brought it back to about $82,200. 2

Underneath that, the tokenized-stock business kept adding numbers. Aave counted close to $4 million in stock-backed loans on Base and $450 million in active V4 loans. 34 Binance put its bStocks product above $1 billion in assets. 5

The week's long-form material is Arthur Hayes, in two interviews published inside the window. No tracked leader published a new essay: Vitalik Buterin's blog feed still ends at "The cryptographic world computer" from September 27, and Hayes's Substack at "Safety First" from September 21.

Arthur Hayes gave two interviews this week, both recorded at TOKEN2049 in Singapore and both published after the conference ended. The first was The Rollup's, published late on the evening of October 12 and running 1 hour 2 minutes. 13 The second was 1000x, with Avi Felman, published on the afternoon of October 14 and running 48 minutes. 7

His answer on AI equities was blunt. Asked whether he is bullish on AI stocks, Hayes said: "No. I think we're wasting trillions of dollars of capital globally." 7 The argument behind it is about unit economics. Data centres get more expensive while compute gets cheaper, so the demand that arrives has to pay enough to service what was built.

Asked to put a number on it, he did. "I'd say it's probably 75% that these companies will not be able to afford the compute commitments without a government bailout," he said. 7 His reasoning: demand will not catch up fast enough to make those contracts profitable at the scale signed. He compared the likely response to 2008, when the United States, China and Europe all recapitalised their banks.

The trade follows from that, and he made it on his own timeline on October 15, the morning of the selloff. "Is AI finally going to dump? IDK but I wouldn't bet either way. Instead just trade the eventual multi-trillion dollar bail out. Long $BTC $ETH," he wrote. 14

On The Rollup he explained where the money comes from. Each 25-basis-point rate hike pushes roughly $25 billion of extra liquidity into financial assets, he said, and the quantity of money matters more than its price. 13 That is how yields and bitcoin can rise together. He added that US commercial bank balance-sheet assets are up about $200 billion, with banks now doing the credit creation the central bank has stopped doing.

The macro catalyst he named was France. If French borrowing costs keep climbing, he said, France would in effect leave the euro. Depositors and foreign bondholders would lose access to their capital through a bail-in, and the state would create banking reserves to buy French assets. 13 That is a forecast about a euro break, and the check on it is the spread between French and German government debt over the next several months.

His answer on the quantum warning was narrower than the framing around it. Asked whether bitcoin is most exposed, Hayes said the practical content of Justin Drake's advice was address hygiene: do not reuse addresses, use the most current signature type, and stay out of the first wave of wallets that would be caught. 13 "You don't need to be Usain Bolt... be faster than your friend," he said, describing who gets hit first. 13 Two days later Buterin's timeline carried hash-based signature aggregation, which is the cryptographic version of the same problem.

FLOP, his agent-currency project, gets one update worth holding: on October 11 he said the testnet ships "in a few weeks." 15

The anchor document of the week is a proposal Babylon Labs filed on Aave's governance forum on October 14. It asks Aave to accept native bitcoin as collateral through Babylon's Trustless Bitcoin Vaults, without a bridge, a wrapper token or a custodian holding the coins. 16

Here is the mechanism. A depositor locks bitcoin in a Taproot output on the Bitcoin chain, and the spending conditions are fixed in the script by everyone in the vault, the depositor included. To claim the coins, a party submits a zero-knowledge proof of an event on Ethereum; any eligible challenger can block a claim that lacks one during a fraud-proof window. Aave V4 accepts only ERC-20 tokens, so each vault is represented by a transfer-restricted ERC-20 that cannot leave the integration and has no admin key. 16

Two new spokes carry it. On the Babylon Spoke, native bitcoin is the only collateral and cannot be borrowed, and each liquidation seizes a single vault. The BTC Vault Swap Spoke lets a liquidator swap the seized vault for wrapped bitcoin at the oracle rate minus a discount, with the wrapped coin borrowed from the Aave Hub. Arbitrageurs holding redemption rights later repay that debt and redeem the bitcoin on the Bitcoin chain. 16

The commercial terms are spelled out. The first $500,000 of qualifying revenue each year goes entirely to the Aave DAO; above that, revenue is split in bands. A token-purchase allocation funds open-market buying of AAVE at 85% and BABY at 15%. 16 Every seized vault is backed by wrapped bitcoin borrowed from the Hub, which creates borrow demand for WBTC, Aave's largest bitcoin reserve and one of its least-used for borrowing.

The size of the pool this draws from is in the proposal. Babylon has activated more than 100,000 BTC since August 2024, peaked at 72,000 BTC and holds about 40,772 BTC, roughly $3.37 billion at the proposal's own valuation. 16 Kulechov's post announcing it ran four lines: "Native Bitcoin collateral coming to Aave. Borrow stablecoins against BTC." 8

Risk parameters are the part still missing. The proposal says Aave's risk service providers will supply them for both spokes, which makes their publication the next thing to read. 16

The rest of Kulechov's week was numbers. Aave said on October 16 that V4 active loans crossed $450 million, and he replied that new markets and deployments are coming. 417 On October 15 he amplified a third-party count showing V4 stablecoin deposits at $1.08 billion and borrows at $417 million, up 68% and 410% respectively over 90 days. 18 Aave's own count that day put stock-backed loans on Base at close to $4 million. 3

One product note completes the picture. USDC and USDT deposits on HyperEVM, Hyperliquid's chain, went live in the Aave mobile app on October 15. 19

Armstrong's own argument this week was about time. "The beauty of 24/7 markets is you can react to news at any time," he wrote on October 18, above Coinbase Markets' note that TSLA perpetual futures had traded after Elon Musk's Roadster event. "Perps and tokenized stocks fix this." 920

His product framing is broader than trading. On October 17 he said Coinbase is "working on making Coinbase the most AI-enabled financial account," so customers get more done with their money. 10 A day earlier he handed builders the feedback loop: point an agent at the Coinbase endpoint, attempt a transaction, and have the agent report where it got stuck. 21

His position on AI spending sits away from the cost-cutting crowd. Replying on October 16 to a report that Accenture would fund only $29 a month of Claude use per employee, he wrote: "NGMI You can control costs in many ways, but usage should be going up exponentially." 22

He also made his case for acquisitions, saying Coinbase has entrepreneurs running key components across the company and has improved at buying companies over time. 23 The related claim from Base, Coinbase's own layer-2 network, came from its lead Jesse Pollak on October 15: "our goal is to make Base the global stock market." 24

Binance published the number that mattered for its tokenized-stock business on October 15: bStocks assets above $1 billion, with users having converted more than $6 billion between bStocks and the underlying shares at 1:1 and zero conversion fee. 5 CZ reposted it, then spent the rest of the week on China.

The sequence started on October 14 with Solana's push into Shanghai. CZ wrote: "It's amazing to see that Solana was able to advertise and even get an office in China. @BNBChain was not able to do this, so far. Hopefully, what's good for one industry player is also good for the rest." 25 Within a day, a Solana event at a hotel in Shanghai was stopped, with several law-enforcement officers at the venue according to an attendee's account. 26 CZ responded: "Sad to see. Looks like they really didn't know the local policies? But it's not the first time either." 27

Commentators then accused him of setting the enforcement in motion. On October 16 he answered in four numbered points, the third of which is the operative one: "My X post was not the trigger. It's now emerged that the Bund building ad was taken down within 10 minutes... I only saw it on X 12-24 hours after the fact." 11 His first point was that he supports any blockchain making progress anywhere.

A separate thread that day was self-inflicted. Having cleared old reposts from his timeline, CZ wrote in Chinese that he had been testing an AI tool, had removed reposts only and no original content, and that nobody needed to over-read it. 28

His other amplification was institutional: BNB Chain opened a forum on October 17 for public comment on its next layer-1, and he pushed it to his followers. 29 He also confirmed that his book, Freedom of Money, reaches Japan on October 19. 30

Buterin published his own working setup on October 16, and it reads like a specification. He wrapped zkAPI, Tor, cover traffic and local prompt rewriting into a daemon for his agent harness: a separate Tor circuit per conversation, requests padded with random cover traffic, and every prompt rewritten by a local model first. 6

He named the limits himself. Tor is "far from optimal" for this, he wrote. The cover traffic holds against passive observers and weakens if the model provider works with the guard relay, so the job wants a purpose-built mixnet with a higher bandwidth multiplier. 6 He also said cheaper zkAPI deposit and withdrawal gas is coming to mainnet.

His second claim was about what zero-knowledge teams should optimise now. Congratulating ZKsync's Airbender team on October 15, he wrote: "At this point, I consider the battle for speed to be definitively won." The top priority for zkEVMs should shift fully to security. 31 The security work he listed has three parts: proving the arithmetic encoding matches the Ethereum specification, a hard ceiling on prover cost per unit of gas in a block, and a proof that the proof system itself is sound.

He spent the same day boosting the hash-based signature route. Reposting the Daisugi v0.3 release note, which verifies 20 SPHINCS signatures through a single aggregate proof, he put post-quantum signature aggregation in front of his audience. 32

His economics note came on October 17. Bitcoin mining splits its cost roughly 50/50 between compute capital spending and electricity, he wrote, while AI inference is almost entirely compute capital spending. 33 Mining pays roughly half its bill to power; inference pays almost all of it to hardware. The buildout Hayes called a waste this week runs on the second cost structure.

Cronje's product news arrived on October 16, when Flying Tulip shipped a new swap venue. His own summary: "Pure onchain swaps, no fees, no gas. Swap and earn yield, swap and use as collateral, or just swap and go." 12 The publisher's detail adds limit orders that earn while pending, a swap-to-lend route, and swapping from a wallet or from a platform balance. 34

The weekly update carries the numbers a reader can check. The Ethereum Lend supply cap for FT rose from 3.65 million to 4.75 million, and the WETH borrow cap went from 650 to 680. 34 Product TVL is $28.3 million. 35 Staked ftUSD yields 8.18% on Ethereum, 9.78% on Sonic and 1.65% on BNB Chain. 36

The buyback accounting explains the vehicle. Withdrawing FT from Perpetual PUTs releases the backing capital, which funds limit buy orders at net asset value, and that FT is burned; roughly $2 million has been bought back that way. Protocol revenue and fees fund separate buybacks at spot, $225,000 so far. 37 Two mechanisms, two funding sources. The first shrinks supply as users exit the put; the second depends on the venue earning fees.

The Federal Reserve meets on October 28, and the CME FedWatch tool showed a 27% probability of a 25-basis-point hike after the inflation prints. 2 A hike into a bond market that rallied through two hot inflation reports is the scenario Hayes's liquidity argument expects to help bitcoin.

FLOP's testnet is due "in a few weeks" by its founder's count, with the mainnet previously guided to the first quarter of 2027. 15

Aave's native-bitcoin proposal moves to its next governance step, and the risk parameters for the two new spokes are the part to read first. 16

The scoreboard for the tokenized-stock argument is split three ways, and each venue reports its own count: Aave's active loans and stock-backed borrows, Coinbase's perp and tokenized-stock volume, and Binance's bStocks assets. 45
