Linera Launches Babbage Testnet

June 17 — Per data from BlockBeats, SpaceX (ticker: SPCX) posted an initial free float ratio of just 4.25% after its IPO, the lowest among major U.S. tech debuts on record. That figure is derived by dividing the number of shares issued in the IPO by total post-IPO common shares outstanding. SpaceX offered 555.56 million shares in its IPO, with total post-IPO common shares hitting 13.08 billion. If the full greenshoe (overallotment) option is exercised, that initial free float ratio would climb to roughly 4.86%. By comparison, other major U.S. tech IPOs had higher initial free floats: Google (2004) at 7.23%, Zoom (2019) at 8.14%, LinkedIn (2011) at 8.30%, Snowflake (2020) at 10.12%, Uber (2019) at 10.70%, Reddit (2024) at 13.84%, and Rivian (2021) at 17.62% — making SpaceX’s IPO’s initial free float the lowest of the group. A low initial free float translates to a limited number of tradable shares in SpaceX’s early secondary trading. Paired with the company’s high fully diluted valua

Serenity’s June 17 post cited a TrendForce report claiming AMD is actively locking in CW (continuous wave) laser supplies via multiple large procurement orders, a move that may only mark the start of a growing supply bottleneck. The Western supply chain has very limited independent capacity left, with only SIVE, AAOI, and potentially Macom holding minimal room for additional orders. This crunch intensified after Lumentum and Coherent locked up their relevant production capacity via long-term deals with Nvidia. For transparency, Serenity disclosed it holds stakes in both SIVE and AAOI. Serenity added that Lumentum itself is facing CW laser supply constraints, leading it to source from Japanese vendors including Sumitomo and Furukawa—firms already operating at near-full production capacity. TrendForce further noted AMD’s push is aimed at ensuring its future capacity won’t be restricted by Nvidia and other major cloud service providers (CSPs). Following Nvidia and AMD’s moves, other hyp

WASHINGTON – The U.S. government announced a $500 million grant on Wednesday (June 17) to SandboxAQ for developing new chemicals and materials critical to domestic semiconductor manufacturing in the U.S., including alternatives to PFAS (per- and polyfluoroalkyl substances). The funding is part of research allocations earmarked under the Chips for America Act, as designated by former President Trump. Prior to this, the Chips for America initiative had allocated $150 million for investments in new semiconductor manufacturing equipment and $2 billion for quantum computing research. Backed by NVIDIA (NVDA.O), SandboxAQ was valued at $5.75 billion in April 2025 and has raised over $1 billion in total capital to date. (Golden Finance)

June 17 — Bitcoin has rallied 6% over the past week, climbing to roughly $65,000 after notching two consecutive weeks of double-digit declines. Research and brokerage firm K33 reports that the share of Bitcoin supply held by long-term holders has hit an all-time high, a potential signal the bear market is nearing its end. Vetle Lunde, K33’s Head of Research, pointed out that a key feature of the 2024–2025 cycle is the reactivation and potential selling of large volumes of long-dormant Bitcoin as prices hit new highs. But since 2026, reactivations of BTC that’s been inactive for over two years have been unusually low. As of June 6, only 218,421 BTC had been reactivated — in comparison, by that same date in 2024, 1.18 million BTC had been reactivated. Lunde said this shows a significant weakening of on-chain selling pressure in 2026 relative to the past two years. Lunde added that the drop in old coin activity indicates long-term holders are less willing to sell, and patient investors

On June 17, Bitcoin dipped below $65,000, edging closer to a critical short-term support level ahead of the Federal Reserve’s upcoming interest rate decision. The Fed will announce its rate decision at 2 a.m. Beijing time on June 18—this week’s primary catalyst for market volatility. Notably, this FOMC meeting is the first held since Kevin Warsh took over as the new Fed Chair, so his post-meeting press conference remarks are being closely watched alongside the rate decision itself. Trader Killa stated the FOMC could set the tone for the rest of June’s market moves. He pointed out BTC is currently building a bullish narrative around this event, though market outcomes are typically priced in well before official news releases. Drawing on recent history, Killa added that FOMC days usually spark more bearish reactions than bullish ones. He warned BTC needs to hold its bullish market structure around current levels (roughly $64,000); if it fails to do so, the crypto could retest its $60,00
